MTL - Returning from the Low-Magic World, I Created My Own Artificial Intelligence-Chapter 494 Put on armor! Fall of the old king

  Chapter 494 Armored! - The old king fell

  Although the beautiful professional team has discussed that the three-pilot aircraft itself cannot decide the final outcome.

  But as if entering no one's land, the performance of preparing to tear off a piece of meat even if they die, still made them feel nervous and dignified.

  Umbrella's special combat ability is too strong, even a limited counterattack is enough for them to suffer a lot of losses.

  At least none of them can guarantee to survive Umbrella's beheading operation!

  In this case, some necessary preparations are also necessary. While quickly sharing information to all places that may be attacked, at the same time immediately tweeted on social media

   "Umbrella dispatched a nuclear warplane! No matter whether it carries a nuclear bomb or not, the pollution caused by the flight alone will have serious consequences. What are you trying to do!"

   While talking, relying on the blessing of "Don Quixote", he quickly produced animated pictures and simple principles.

   Now the conflict between Damei and Umbrella can be said to have attracted worldwide attention.

  Even people at work are distracted.

  Worried that things will get out of hand.

  Now that Umbrella's fighter plane has just taken off, Damei's attitude of jumping immediately has really surprised many people.

  It’s just a triplane, as for it?

  But when they heard Damei’s words and saw Umbrella’s plane, everyone felt unbelievable!

   "What the hell? Straight into space?"

   "Fuck! Aerospace fighter!"

   "Nuclear-powered engine? Is this thing safe for people to go up? Is it dangerous?"

   "Hey, no wonder you are jumping. If Umbrella uses this structure, then the air heated by the reactor will spray out the pollution by the way, wherever it goes."

   "Actually, this is enough to show Umbrella's determination. I'd rather die than die!"

   "Hehe, you deserve it! This time, it was a beautiful fault!"

   "Retribution!"

   "..."

  Yoko, who was in Tokyo, was also paying attention to this matter at this time. When she learned that a plane was flying towards this direction, she was both excited and worried.

   "Hey, unfortunately there is only one plane, if there is more time..."

  However, just as she sighed, the air defense sirens blared outside!

  The sudden sound of the air defense alarm was so unexpected that Yoko's face was full of astonishment.

   Isn't it, so fast?

  But she soon realized that this quick and brief message had already taken up some time.

   And if it is really the speed they broadcast, it seems that it is normal to sound the air defense alarm now!

   Then Yoko came to the window, seeing the big and beautiful soldiers beside the armored vehicles below also began to panic, as if ready to evade at any time.

  Even if Umbrella is just a fighter plane, it still brings a huge deterrent!

  Because Umbrella's cutting-edge force is really strong!

   "Look above!"

  A soldier next to an armored vehicle pointed to the sky in horror and said to his teammates.

   Let the companions also look up.

   And many people nearby were watching them from the window. Seeing their reactions and raised fingers, they also looked up at the sky.

   It was broad daylight at this time, as if a meteorite with a tail flame appeared in the sky, something had entered the atmosphere!

  Many people were zooming in on Umbrella's mobile phone lens, and it was obvious that it was a speeding fighter plane!

   It is one of Umbrella's three fighters!

   Sure enough, they divided their troops into three groups, and this one was responsible for coming to Tokyo.

   This not only made many neon people feel excited and felt that the savior had come, but also made many people worry.

   It’s okay for such a big lala to come over!

  Although the speed is fast, why does it feel like the plane is slowing down? !

  The shooting looks like the bottom of the plane is moving in an inclined direction, which is not the standard direction of the nose aerodynamics. It seems that the wings are specially used to increase the force-bearing area to slow down!

   What went wrong?

   Almost when this idea just appeared on their side, and many people in other regions also watched this side worry through the live broadcast of these people.

  A string of anti-aircraft missiles is densely packed and galloping towards the fighter plane in the sky!

  In addition, you can also see that Damei's plane here has also taken off, and a large group of fighter planes are encircling the sky, dragging out airways in the air.

  The roar of fighter planes is deafening.

  In this kind of scene, under the situation of complete blockade and double-teaming, the nervous big and beautiful soldier at the beginning of the armored vehicle below finally breathed a sigh of relief and relaxed

   "Haha, I was taken aback. I didn't expect him to slow down at his own risk."

   "What can I do if I don't slow down? This is not a missile, it just hit me. Is it possible that I have to learn their flying skills when I come to Neon?"

  The soldier next to him was obviously also relieved.

  At the same time, in the underground air defense facility of the Daimei command camp in Yokosuka, after learning that Umbrella's plane appeared over Tokyo with such a big roar, it slowed down and was captured by a special radar.

  The commander gave the order to attack decisively while heaving a sigh of relief!

   "Don't be stingy with anti-aircraft missiles! Worry about the interception system on their planes, the threshold of defeating the planes must be reached! Be sure to shoot them down!"

  In fact, at first he really had no idea.

  A plane cannot be reversed. According to Umbrella's technology and tactics, beheading is enough!

  So he entered the underground bunker as soon as he got the news.

  As long as this bunker is not the center of the nuclear explosion, it is enough for him to command!

   I just didn't expect that the opponent didn't go straight to Yokosuka, but came to the sky above Tokyo first, and slowed down?

   This is not courting death!

   Just as the Aegis in Tokyo Bay began to explode, the Patriot air defense missiles on the roadbed also came out in full force!

   There are also fighter planes that took off ahead of time when they got the news, and the opponent is already unable to escape!

   "On the front line screen, I want to witness the fall of Umbrella with my own eyes!"

  The commander's domineering opening then connected him with the perspective of a P3 reconnaissance plane.

  P3 is mainly used for anti-submarine warfare at sea, and its flying speed is not fast, so it follows behind the main force.

   But it is also true, from the perspective of P3, you can roughly see the whole picture!

  The 'fireball' falling rapidly from the sky, the anti-aircraft missiles soaring into the sky, and a large number of F16 fighters constantly 'overtaking' passing behind, all highlighted the powerlessness of the fireball in the air.

   "Haha, dumplings are already made, it's hard to fly!"

  When Gaul was fighting beyond visual range, Umbrella directly wiped out the Gaul Air Force from a long distance, and then went back to replenish ammunition safely.

   But this time, directly into the city, into the core area, what can you do?

  The speed of anti-aircraft missiles is extremely fast, and can reach speeds above Mach 5. In addition, the fighter plane that fell from the sky still maintains a high speed even if it slows down.

   The first group of anti-aircraft missiles to arrive has densely covered the past!

   There was no expected laser interception, jamming bombs and evasion. In an instant, a large number of anti-aircraft missiles had hit the target and exploded!

   After the speed slowed down, it was still locked, and it was targeted by such a number of anti-aircraft missiles. There was no possibility of escape or escape.

  The superposition of anti-aircraft missiles cannot increase the probability of interception to more than 100%, but it can indeed reach close to 100% after the number is increased!

  A series of explosions appeared in the sky, bursting out clusters of fire and smoke from the explosion.

   "Oh, it's just that the first wave is gone..."

  The commander smiled slightly, admiring the exploding fireworks in front of him.

  At the same time, a large number of residents of Tokyo, as well as the handsome soldiers on the ground, and the pilots of the handsome fighter jets who were flying over also saw the flames from the serial explosions.

  In addition, many local and live viewers from all over the world also watched the smoke and dust in the sky.

  Some people sighed, while others sneered.

  But then it was a little surprising that the wreckage of the plane fell and never fell out of the remaining smoke.

  Fried to pieces?

  Impossible, anti-aircraft missiles are not armor-piercing projectiles, and planes are also unarmored, as long as the hit and speed are enough, it is the same as the difference between a javelin and a stinger.

  Anti-ship missiles generally cruise at subsonic speeds, and the warhead loads hundreds of kilograms of ammunition, but the ammunition load of anti-aircraft missiles is generally several kilograms.

  So even if enough missiles are hit, the wreckage will not appear.

   As for not being shot down, that is even more impossible. How could so many missiles bomb the plane and fail to be shot down.

  Besides, at the speed of that plane, it would have flown out of the smoke zone long before it was shot down.

   But amidst the doubts, under the gazes of all parties, there seemed to be two bright lights in the smoke.

  The airflow swept across, and the smoke and dust scattered!

  The 'figure' behind the smoke was revealed.

  A humanoid mech with a gorgeous appearance and a faint trace of the previous fighter is standing in the sky. A conical engine behind it exudes a faint blue light.

  At the same time, the mechs were holding an anti-aircraft missile to play with.

   It seemed that after sensing the sight of attention, he reached out and crushed the missile and caused an explosion.

   But everyone found that even though the anti-aircraft missile exploded in his hands, it didn't cause any waves!

   Not even a trace of black marks left behind!

   "Umbrella's traditional formula, even the old godmother would not touch it, blackened or something, so it won't be..."

  A sound came out from the mecha, both external sound and radio frequency.

   "You guys seem a little disappointed that you were not shot down, but sorry, I'm an armored unit..."

  Chapter six hundred and eighty

  The anti-strike capability of modern aircraft carriers has been said many times. Ordinary anti-ship cruise missiles and even torpedoes cannot sink them, and anti-aircraft missiles are even more ridiculous.

  But the aircraft carrier has enough volume, and it has enough thick armor!

  However, now a plane, no, it should be said that it is a mecha, while hovering in the sky, while firing a volley of anti-aircraft missiles, it failed to leave even a trace, which really made everyone who saw this place stunned.

   Damn it!

   Umbrella!

  伱 What kind of thing did you take out!

   "Our company has signed a security maintenance agreement with Nihong. This time I came here just to understand the struggle, but you have no reason to attack me. Should I surrender, or should I send you away?"

  The mecha suspended in the air said these words very elegantly.

   Let the fighter planes that are still approaching rapidly respond by launching their own missiles!

  At the same time, the headquarters also issued orders hoarsely.

   "Use a cruise missile! If you can't hit it, even if you hit it, you have to knock it down!"

   Completely ignoring the fastest anti-aircraft missile like a fly swatter, the engine on the back of this mecha seems to start sucking in the surrounding air crazily.

  The next moment, the multiple injection ports on the upper and lower parts of the mech ejected highly compressed hot air.

  Relying on this huge thrust that can be changed at will, it is easy for the mecha to make all kinds of incredible actions and movements in midair!

   Almost like a flash, it wiped off cruise missiles one after another, and rushed towards the fighter group in front.

   And those cruise missiles that lost their targets all crashed into downtown Tokyo, setting off bursts of explosions.

   At the same time, the mech raised its hand and shook, and two wrist blades appeared, and then the direct high-frequency vibration instantly became blurred.

  唰~

   Cut a passing F16 in half like a hot knife cutting butter!

   Hot red marks can still be seen on the incision!

  Not enough ammo?

   Indeed, physical ammunition, even the projectiles carried by electromagnetic weapons, is limited in number!

  Attacking this number of targets is a bit wasteful.

  Then you can chop it!

  Residents in Tokyo, today is really full of twists and turns, and you can constantly see missiles and fighter planes falling from the sky.

   One after another, the fighter planes were cut off. Looking up, I watched the mecha rushing into the flock like a tiger rushing into the flock and mowing the grass like a tiger!

  A plane is like a kite with a broken string.

   Some exploded in the air, and some were cut into two sections and then fell!

   And that mecha, relying on the super mobility of the all-round jet and the unrivaled control technology of the driver, even if it explodes at close range, it seems to be able to follow the direction of the explosion to avoid damage.

   Even the explosion shock wave may not be able to catch up!

  Watch him chop down one plane after another like dancing on a tightrope!

   "Don't underestimate me!"

  An ace pilot kept pulling the joystick, and the plane swayed to the limit of the maximum acceleration.

   But the trajectory of the aircraft that needs to rely entirely on aerodynamics to complete the flight is really easy to capture. With a dodge, the mecha came to its side, and then without even looking at it, it cut the aircraft into two sections with a knife.

  The incision also emitted a melting red light, and then exploded in the air...

  All beings are equal in front of mechs!

   It doesn't matter whether it's an ace or a miscellaneous fish, whether it's running away or fighting.

   It's like an adult jumping into kindergarten, there is no way to compete!

  No matter how many there are!

   In a very short period of time, all the planes on the entire side were emptied directly.

  When the other planes that were flying over saw them, they turned around and left without looking back.

   threw beautiful arcs in the air one by one.

Just kidding!

  Send to die? !

  However, after annihilating the mecha of one plane, turning around, he directly pulled out a gun barrel to complete the splicing.

  The enlarged version of the Umbrella Electromagnetic Rifle appeared on the mecha, which made people feel terrifying!

   But then the mecha seemed to think of something again, and instead of pulling the trigger, it popped out the shoulder gun.

  BIUBIU~

   Two beams of high-energy lasers destroyed two fighters in an instant

   "Uh, I'm just showing off the operation, it's not that I don't have long-range weapons."

   It was still the driver's lazy voice, which made everyone's scalp tingle.

   Another terrifying weapon with such a large muzzle, and another shoulder-resistant high-intensity laser weapon!

this…

   What the **** is this? !

   "I don't like boring killings, surrender can live."

   "We Surrender!"

  The radio channel was almost returned in seconds, completely bypassing the commander in the air defense bunker.

   And when the mecha looked down at the armored vehicles below, those big and beautiful soldiers who were being targeted also quickly threw their guns aside and raised their hands.

   "Very good, the law and order in Tokyo is maintained, the task of repelling the robbers has been completed, remember to pay money..."

  Looking down at Tokyo, where the missiles and fighter planes crashed, Li Yao calmly announced the success of the mission...

  …

   "What? Mech, what nonsense are you talking about?"

Captain Henry was still talking in front of the reporter's live broadcast, commenting on Umbrella's "nuclear-powered aircraft", and while giving praise, he also pointed out shortcomings, how to deal with it in the future, and various conflicts. possible.

   is expressing that the biggest trouble with nuclear-powered fighters is the nuclear pollution produced after they are shot down.

  However, at this moment, the contact from Tokyo made him a little confused.

  I am a professional military personnel, and I used to be an ace pilot, so don't lie to me!

  What’s so good about mechs?

   Such a big target, so expensive, it’s just ridiculous to lose it with one missile.

   "Really! Be prepared! There have been a lot of surrenders on my side, and morale has been completely broken! It's really hopeless! I really can't win!"

  The commander of Yokosuka kept yelling into the walkie-talkie, his face was full of despair, and his eyes were bloodshot.

  In fact, he still has a lot of theoretical strength in his hands. One fleet sank, but morale has collapsed.

   Watching that rush into the group of planes and kill them randomly, shooting down a large number of planes like chopping melons and vegetables.

   There is melee and laser.

  Temo has unlimited firepower!

   Who has the courage to fight? !

   "You will definitely receive official news soon, I just remind you kindly as a friend! Take care, don't die..."

   After speaking, he sighed and hung up the dedicated line.

  Because the mecha had stopped outside the bunker at this time, the sharp blade in his hand cut it at will, like cutting tofu, peeling off a piece of reinforced concrete in the underground bunker!

  Although it is definitely not penetrated, it can be seen from this performance that as long as the opponent wants to come in, the most they can do is dig.

"I surrender…"

   After saying this to the radio, the commander seemed to have aged a lot.

  This is what is called not to worry about...

   heh~

  …

  Captain Henry on the other side was also a little confused when he heard the hangup over there.

  But at this moment, a signal response appeared on the radar, and a notification was given immediately.

   "The enemy has appeared, so fast!"

   "Don't panic, as long as you can find it."

  Henry said seriously.

  Two of the three planes accelerated into space, and the Tokyo one arrived first.

   What I am facing here should be the only one approaching in the atmosphere...

   But at this moment, he got an emergency contact again, this time from the headquarters, which made him feel a sudden, what the kid didn't say before was true, right?

   But before he got in touch, the radar officer said in horror

   "Too fast! Appearing! No reaction time!"

   At this moment, the clouds in the sky were instantly dispersed, and a gorgeous fighter plane swooped down at high speed, as if it was about to hit their aircraft carrier!

   Before Captain Henry got nervous, he stared wide-eyed at the plane that broke through the clouds and completed its transformation in the air. It really turned into a mecha!

   "Haha! Hahaha! This is the romance of a man!"

  There was a burst of wanton laughter from the public radio frequency and the external sound of the mecha.

   Then I watched the mech during the high-speed landing process reach out and draw out two large knives from behind, and then assembled them together.

   After assembly, it continued to pop out for a distance and became longer.

   It is really a forty-meter sword!

   "I am Gundam!"

  When~

  The high-speed mecha stepped onto the deck of the aircraft carrier before everyone could react. Due to the angle of the impact of the landing, a large amount of sparks erupted from the soles of the feet and the deck.

   Just one impact threw many planes on the deck into the sea.

  Following the flames rubbing against the deck, the mecha turned around on the spot, took the 40-meter broadsword around, and cut off the bridge of the aircraft carrier in an instant!

Captain Henry and his entourage died suddenly on the spot, leaving another group of reporters and photographers who were filming the deck outside stunned. They watched the mecha turn around under the strong wind that was almost thrown into the sea. The latter bounce again jumped into the sky on the stern of the carrier.

   Then there was another burst of deformation and turned into an aircraft attitude accompanied by radio

   "Wow~"

  's strange cry, accelerated instantly and broke through the clouds again and disappeared...

   With many warships escorting and a large number of aircraft taking off, the aircraft carrier bridge was cut off in a flash, and then walked away!

   Taking the head of the enemy general among thousands of troops is like picking something out of a bag!

  As the other party left, everyone with a blank face could vaguely realize that they were more than this fleet.

   Is this in a hurry...

  Chapter 681 The Fall of the Old King

  The fighter plane that descended from the sky turned into a mech in the air, rubbed against the deck of the aircraft carrier and produced a series of sparks. With one turn and slash, the bridge was cut in two, and finally rose into the air.

   The whole time did not exceed one minute, leaving a mess on the deck of the aircraft carrier.

  The carrier-based aircraft that was blown into the sea, the bridge that melted molten iron and glowed red remained in the incision.

   And the surviving crew members who came out one after another were all dazed.

  The aircraft carrier was almost undamaged, the bridge was cut in half, and then the mecha was vacated.

  Looking at the sky that has turned away from the fighter planes, and now you can't even see a small dot, all the survivors on the aircraft carrier, as well as the beautiful soldiers from the nearby fleet, and even the fighter pilots who have already taken off.

   At this time, a kind of silence was maintained.

  The visual impact and shock before, if it weren't for the bare bridge on the aircraft carrier, it would feel like a dream, so unreal!

   Is this the mecha that was reported earlier?

   turned out to be true? !

this…

  Because deck reporters were taking pictures of takeoffs, the attack on the beautiful aircraft carrier was immediately known to the world!

   Straight to the point in less than a minute!

   And just watched the performance of chopping melons and vegetables in the sky above Tokyo, so it is completely predictable that if Umbrella's mecha is not in a hurry, there will be no problem in destroying this fleet!

  The 40-meter-long ship-slashing knife can't be carried by a ship!

   Obviously, the plane...

No!

   It should be that the target of this mech is the various fleets dispatched by Daxie!

  Although it departs from various bases around the world in all directions, with the maneuverability and performance of its aircraft attitude, combined with the speed of the previous attack, the battle may be completed within an hour or even half an hour!

   "Fuck! Is it really a mecha?"

   "I just said that the control platform in "Star World" is not right, it is too real, is this the application of Umbrella's mech technology?"

   "This shit! Just finished watching the feast of the game, and then the game is reflected in reality?"

  “I even once thought that the video in Tokyo was an AI-synthesized video.”

   "Hehe, I think so now..."

   "There is still one that hasn't landed yet."

"this…"

   "..."

   Regardless of the uproar caused by the outside world, Umbrella's mechs have always completed their tasks step by step.

  Tokyo Mecha dominated the audience, accepted the surrender of the beautiful garrison, and then went straight to Seoul.

  The Pacific Mecha swept all the big and beautiful fleets!

   The first team can be called a surprise attack, directly cutting the bridge.

   And when it arrived at the second fleet, it was already facing an imminent blockade.

   "Shoot him down! Be sure to knock him down! He will be knocked down!"

  All fighter planes took off early, and after discovering the traces in advance, the fleet commander was hysterical.

  After that, he saw the air fighter group being slaughtered like tigers like sheep.

  The maneuverability and acceleration are completely unreasonable. I don't know how the driver inside resists the acceleration!

  Air-to-air missiles that have a chance to hit can be directly attacked without damage.

  The cruise missiles that may pose a threat can't keep up with the opponent's speed at all!

   Not to mention the dexterity of switching at will, and the supplement of laser attacks from time to time!

  It is not possible to directly destroy warships with laser attacks, but destroying fighter planes and cruise missiles is a matter of choice!

   One after another fighter planes fell, and soon the remaining fighter planes also chose to escape, and were caught up and cut down one by one.

   And compared to the first beheading operation, after facing the attack this time, Mori Ryuichi stepped on every big and beautiful battleship screaming strangely, and all the bridges were cut off.

   When it finally landed on a Littoral Combat Ship, it even cut downwards, cutting the entire battleship into two sections!

   Then when he went to the third fleet, what he faced was the signal of the fleet’s surrender...

  …

   "What? It's impossible!"

   “It’s all synthetic videos! It’s all fake news!”

  The pretty reporter personally appeared in front of the camera and explained frantically. At this time, reporters from all walks of life were already standing in front of the White House.

   But at this time, he was still stubborn and unwilling to admit it.

"That…"

   Before another reporter asked a question, the red meteorite brilliance appeared in the sky.

   F22s soared into the sky, and the anti-aircraft missiles poured down without reservation, and directly reproduced the battle situation in Tokyo in front of many reporters!

  Missiles and fighter planes fell all around like intensive bombing.

  The beautiful speaker completely ignored the pulling of the security personnel, and stood hysterically on the spot and shouted at the sky

   "Come on! I'm not afraid of you!"

  However, the mechas in the sky didn't take a second look, they just silently harvested various fighters over there.

  Although many of the reporters left behind started to flee, there are also many who are not afraid of death.

   Start shooting in this environment.

  Even if the wreckage of the fighter plane fell not far away, the heat wave could be clearly felt, but it still did not shake the last few fanatics.

  The pretty talker also stood there with an ugly face all the time, refusing any evacuation.

  I have just moved here, and I will never leave!

   With the last F22 being cut down.

  The black mech slowly landed on the lawn of the white house.

  The jet of air sent the weeds flying across the white house, and the strong wind swept the entire venue.

  The dark and cool fuselage is full of streamlined and smooth shell, and the air next to it seems a little distorted because of the high temperature of the anti-aircraft missile explosion.

  Standing on the remnant lawn will burn the nearby green lawn.

  The laser cannons on the shoulders and the wrist blades on the hands seemed to be still steaming hot.

   Witness the previous massacre in the air!

  Subsequently, Cheng Xue's cold voice appeared on the mecha external sound and radio frequency

   "Your Excellency, the speaker, now that you have been captured by me, it is up to you to decide whether to fight or not."

   And the speaker had no time to take care of his blond hair, which looked a little embarrassed because of the strong wind that landed before.

  I can only stand on the stage and still keep waving my fists

   "You are invading! This is aggression! We will never let it go! We have the strongest nuclear strike capability!"

  The hysterical voice was also expressed in front of the camera.

  As soon as the nuclear blackmail came out, it seemed that the whole world had entered the haze of a nuclear explosion.

   "Of course, this is your trump card, but after our satellites and space elevators are built, although all interceptions will not be achieved, the protection of Penglai is still not a big problem."

  Cheng Xue's voice seemed very calm, then raised the wrist blade in her hand and pointed it condescendingly at the other party.

   "Maybe, you can try..."

   Maybe you can give it a try!

  Calm, polite but with an indescribable domineering, everyone watching the live broadcast of the reporters couldn't help feeling suffocated.

   "So strong!"

   "How domineering!"

   "But Penglai can ensure that nothing will happen, other places can't."

   "There is no winner at that point."

   "Sane..."

   "Umbrella has a retreat, it doesn't matter, then the one who retreats must be beautiful..."

   Sure enough, the person who was clamoring to grow mushrooms and blackmailed him was like a **** that had been strangled, unable to respond for a long time.

  The other party's attitude is pushing one's side to the wall!

  Umbrella can at least ensure that Penglai is safe!

  Once it is really activated, human beings will go back at least fifty years!

   And Umbrella, who is sitting in Penglai, will be the final winner!

indeed…

   is lost!

   This time you are stronger!

   “We are willing to pay compensation.”

  The excited speaker finally sighed at this moment, letting go of his dignity.

  Global live broadcast, under the witness of everyone, under the threat of the three mechs, the bald eagle who has always dominated Bluestar lowered its proud head.

  It doesn’t matter if it’s true or false, and it doesn’t matter whether you will be convinced in the future.

...

  ——

   Update completed~

   There are only so many updates, there is no way, the rhythm is actually quite fast now, it is really impossible to read the content of these three days, the outline stream of consciousness...
