Apocalypse: I Built the Infinite Train-Chapter 451: Cliffside, Nuclear Explosion!

Empty! Empty! Empty!

The sounds of water pressure, collisions, and metal clashing filled every carriage of the Infinite. Outside the portholes, the murky seawater revealed only glimpses of a massive black-and-white patterned sea serpent, its body gradually elongating as the train descended.

In the deep waters, countless bioluminescent plankton emitting a ghostly green glow began to appear densely, clearly indicating the train was rapidly plunging downward.

“Laine, the descent is too fast. If we hit any pressure-resistant shell, it could cause severe deformation.”

“At this speed, if we crash straight into the super whirlpool array, we might all just disintegrate on the spot!”

Behind the Infinite, the Abyssal nuclear submarine carrying hundreds from the Falcon Sea Group was diving at a steep angle. Its ballast tanks were fully flooded, and the descent speed had reached its limit. Alarms blared inside the vessel, but Laine showed no hesitation, fixated on the target on the monitor and decisively issuing orders.

“Ignore everything else. Stick close to Lin. We only have one chance!”

Boom! Boom! Boom!

The continental shelf trembled, the seawater boiled, and the submarine base was collapsing on a large scale. The geothermal well's boiling lava completely engulfed the Deep-3 geothermal emplacement device’s release mechanism. Magma surged into the base’s tunnels and laboratories, everywhere was ablaze and bursting apart.

The sky had darkened completely;the black canopy merged indistinguishably with the churning sea surface, blurring the line between night and ocean.

Onboard the Infinite, the near-vertical descent had everyone on edge. The full-speed plunge caused the special metal pressure-resistant shell outside to emit metallic wails, accompanied by sharp ‘teng-teng-teng’ sounds. Everyone in the carriages held their breath at that moment.

Phase one: descending to the abyssal cliff at 2,260 meters.

Phase two: entering the underwater super whirlpool array of the Silent Abyss Whirlpool.

If the Infinite and the submarine survived phase two without being crushed by water pressure or torn apart by sea monsters, phase three would be to ride this deep-sea current out of the Haiyan Island waters.

However, at this moment, the Infinite, marked at level four, seemed like a lighthouse ignoring the terrain in this pitch-black sea area. Whether the creatures on the offshore island or the sea monsters deep underwater, all were gathering around.

So Lin’s plan was to use the geothermal core device to trigger a high-energy geothermal wave, clearing out the abnormal entities while drawing their attention with an even bigger “lighthouse,” then use the Silver Dragon Ten Thousand Mistakes’ dimensional bubbles to perform a vanishing act amid billions of sea monsters’ encirclement.

Lin knew his idea was bold and probably hard to achieve perfectly, but there was no other option. Detonating the geothermal well was the most likely effective plan. At that moment, Ding Junyi’s words struck a chord in Lin’s mind.

“Bloom?”

No way, not the Silver Dragon Ten Thousand Mistakes acting up now.

“What do you mean by bloom?!”

Ding Junyi said nothing, simply raising a vine to bring the Silver Dragon Ten Thousand Mistakes before Lin. His gaze fell on the purple flowing light inside the disaster plant’s roots, which now shone more brilliantly than ever. At the tip of the uppermost leaf, a white flower bud the size of a fingernail had sprouted.

This bud was clearly different from what they had seen before in the No. 5 Star Abyss. The petals seemed to shimmer with geometric fragments of light, as if projecting a dimensional space. In Lin’s view, several petals were slowly unfolding. His eyes narrowed as he stared into the center of the bud, which was pitch black inside. Just by looking, he felt that the dark core was expanding as if trying to suck him in, with countless points of cosmic light within the darkness.

13…

12…

At that moment, Tong Yan noticed that the time on his watch was running out. He felt himself sinking into the white darkness. Flickering images flashed across his vision.

A massive explosion that changed the sky and earth, illuminating the sea with a giant mushroom cloud. Roiling sea monsters, the white silhouette of the Oceanic Titan in the celestial ocean, the white vortex of the super whirlpool, screams inside the Limited train, the ticking of clocks, the metal die repeating numbers 5 and 6, and the countdown on his retina reaching 00:00:01 before the flood of blood.

Hiss!

The Silver Dragon suddenly snapped out of the white darkness illusion and took a deep breath, glancing at the countdown he had set on his watch.

15…

14…

What was happening?

In front of him, the abnormal bud on the Silver Dragon Ten Thousand Mistakes was slowly opening. At the same time, Ding Junyi’s voice came through.

“This is a disaster plant state more mature or advanced than the bud. I’m not sure what results will occur once it’s activated.”

Lin frowned, looking at Ding Junyi. “What does that mean? Can we use it now or not?”

“Yes.”

“Good!”

“Lin Xian!!!” Lin grabbed the Silver Dragon Ten Thousand Mistakes cultivation pod tightly just as KIKI shouted in his earpiece, “We’re about to plunge into the deep-sea cliff!”

[Danger, I’m detecting a large number of biological signals outside the channel’s waters.]

13, 12…

Lin’s heart sank. “How many?”

Beep. Viola’s sonar image appeared on Lin’s power armor holographic screen, the circular scan path revealing the entire screen in blood-red!

Empty! Empty! Empty!

The Infinite crashed into a surging underwater current, the entire train violently shaking. The deepwater port below the offshore island was a steep dark slope. In the abyssal cliff area was a narrow ridge valley, where massive ocean currents suddenly accelerated, sucking seawater directly into the abyss below.

Thanks to this natural terrain and ocean current, the Federation had built a secret submarine base here, allowing silent and direct access to depths of 1,000 to 1,200 meters.

“This isn’t good!”

“What do we do? Should we fight our way out together?”

Voices from Ning Jing, Qian Dele, and others intersected.

“I can freeze a section of seawater to create an environment for our descent. Once we enter that whirlpool, maybe we can shake them off.” Laine’s voice came over the comm.

“Lin, just 300 meters to the channel exit!” Chen Sixuan shouted.

Beep beep, beep beep. The watch’s nightfall alert sounded repeatedly.

“Don’t worry about it. Everyone brace for impact. Laine, you just follow closely behind the Infinite!”

9…

8…

7…

In carriage three, Lin shouted and grabbed the Silver Dragon Ten Thousand Mistakes’ cultivation pod, flying towards the cockpit. The power armor adjusted its thrusters for rapid descent.

At that moment, several green vines grabbed Lin and the Silver Dragon Ten Thousand Mistakes, stabilizing him. Ding Junyi controlled the vines like her own limbs and quickly approached, her cold voice saying,

“I’ll help you!”

Click, click, click!

The vines twisted like countless nimble tentacles, quickly building a smooth path inside the carriage, then followed Lin towards the cockpit.

KIKI in carriage two immediately followed.

“Ryunosuke, head to the rear carriages. Stabilize the Infinite and the people inside!”

Ryunosuke responded instantly, using telekinesis to fly quickly to the upper carriages.

Lin bypassed carriages one and two, entering the bottom cockpit. Chen Sixuan, clad in battle armor, secured herself tightly in her seat. Viola monitored the entire train with precision. Seeing Lin arrive, Chen pointed at the multicolored giant serpent passing outside the window.

“We’re almost at the bottom of the cliff. That monster is blocking the passage. There must be plenty of abnormal entities outside. What now?!”

“We just break through!” Lin clenched his teeth fiercely. Ahead, underwater explosions roared, and the entire Infinite trembled under immense pressure.

“The explosion is imminent, KIKI, no matter what you see, smash through!”

“Got it!” KIKI responded loudly, unleashing her telekinetic power, a glowing light radiating from her body.

“Director Ding, countdown finished, initiate Silver Dragon Ten Thousand Mistakes immediately.”

“Understood.”

Empty! Empty! Empty!

The turbulent water surged as the Infinite’s descent speed increased, rapidly surpassing 900 meters, then 1,000 meters.

In view was the massive black-and-white patterned sea serpent’s body, resembling a towering underwater pillar descending straight down. Its diameter was shrinking, as if approaching its tail.

Meanwhile, the roiling vortex stirred up the seabed and cliff into a murky mess. The Infinite plunged into the turbid water, and the porthole lights vanished instantly, leaving only darkness. Now relying on the detectors and Viola’s precise full-range control, the Infinite continued its rapid descent.

Rumble!

Under a thunderous impact, the Infinite began violently shaking, as if thrown into a giant blender, spinning underwater. Inside the carriages, everyone was dizzy and subjected to repeated shockwaves. Lin knew the Infinite was breaking out of the vortex’s massive suction. His heart tightened as he fixed his gaze on the countdown.

Suddenly, the violent shaking stopped abruptly, and the explosive sounds inside ceased. The Infinite burst from the murky currents into calm waters. Its near-vertical diving posture stabilized. They had finally entered the deep-sea area of the Pacific Ocean!

“Lin!”

The sharp-eyed Chen Sixuan suddenly whispered. The sonar alarm emitted a piercing blast. Those who had just steadied themselves through the violent shaking looked out through the starry window, and everyone’s breath caught!

In the pitch-black water, countless enormous shadows blotted out the sea surface, filling the entire area. The Infinite’s lights illuminated only finned bone spikes, while deeper within, countless whip-like tentacles swayed like a sea forest.

Perhaps it was a single creature or countless ones. The sonar screen was all blood-red, unable to clearly identify their form or type.

At this moment, the Infinite and the Abyss-class nuclear submarine, having just burst from the current, were like worms floating before a swarm of deep-sea titans, all eyes staring.

Beep!

Instantly, the spirit value monitors of everyone aboard the Infinite and the Abyss-class submarine simultaneously blared.

Level 5 Mark!

All personnel locked on!

At this moment, Lin felt a chill surge from his feet to the crown of his head. He had no time to ponder whether there were S-level entities in the abyssal cliff ahead or if the numerous special-levels were the reason for the level 5 mark.

Silver Dragon looked at Chen Sixuan. Right then, the Silver Dragon Ten Thousand Mistakes’ flower bud hadn’t fully bloomed, and the time on Silver Dragon’s watch reached zero.

3…

2…

1…

Beep. Simultaneously with Tong Yan’s watch, the ground-based weapon’s detonation fuse beneath the reactor, planted by Silver Dragon, began.

At that moment, the Deep-3 geothermal nuclear emplacement device’s molten titanium alloy shell emitted a final dazzling blue light in the magma. The Hyperion directional constraint cannon’s superconducting rings suddenly contracted! The chain reaction device implanted in the reactor core activated instantly, and the fusion energy released by the honeycomb fuel rod arrays surpassed the critical point in a fraction of a second.

Above the offshore island, a golden-white star suddenly lit up the black sky and ocean!

No sound, only a blinding light that almost illuminated heaven and earth.

Within a 1.2-kilometer radius centered on the geothermal well, seawater was forcibly evacuated, creating a vacuum bubble a kilometer in diameter.

The swarms of sea worm snakes and countless abnormal entities burrowing into the seabed from the Sea Rock Prison were instantly vaporized by temperatures reaching 170 million degrees Celsius. The lava flow of the geothermal well was pushed back into the earth by the fusion shockwave.

The entire offshore island began to collapse like a sand tower from the center. When the prison’s high walls fell, the debris vaporized midair into sulfur smoke clouds. The steaming seawater carried the intense heat radiation, slamming back into the vacuum zone and forming a kilometer-high circular tsunami wall. 𝗳𝚛𝗲𝕖𝚠𝚎𝚋𝗻𝗼𝕧𝗲𝐥.𝚌𝚘𝐦

This enormous sea star swept away the storm clouds in the sky, creating a huge darkened void in the canopy. From high above, one could see countless sea monsters and abnormal entities near the island being wiped out, spraying a ring of black mist vapor diffusing across the sea surface.

Boom! Boom!

The contracting fusion fireball triggered secondary xenon-xenon fusion, sending a pulsating shockwave racing along the Pacific Ocean ridge. The seabed layers shattered and lifted like eggshells. The massive shockwave traveled through seawater and seabed, striking the abyssal cliff seabed ahead in seconds.

At this moment, the Infinite and the submarine drifting in the deep sea were like capsules shaking inside a water bottle, suddenly pushed below the cliff. Simultaneously, the dense sea monsters in the cliff were washed aside.

“Ah!!!”

Screams erupted inside the Infinite, tossed wildly by the water. Direction was lost amidst the terrifying currents. Outside the portholes, it looked as if the Infinite was racing past countless horrifying abyssal monsters.

Whirlpool-like giant mouths, ridge-like fin edges, compound eyes of a multi-jointed giant ringed creature...

Lin held Chen Sixuan tightly. The cockpit was stabilized by KIKI’s telekinetic power, while behind them, Ryunosuke also used his abilities to protect the passengers in the carriages from being torn apart by the violent turbulence.

At this moment, Lin seemed to hear strange cries—some like abyssal wails, others like earth’s crust groans. He raised his hand, pointing outside the porthole, ready to activate the Gravitational Lens.

Under the rotating headlamp light, a massive abyssal mouth lined with spiral sharp teeth like a volcanic crater surged forward with powerful water pressure suction, aiming straight for the Infinite as if to swallow it whole.

Lin’s eyes sharpened as he prepared to strike alongside KIKI.

Who could have predicted that in the next instant, several giant vines covered in deep red thunderbolts stretched forward at a visible speed, their diameter rapidly expanding from half a meter to several meters—each thicker and stronger than the Infinite itself. The spiraling vines pierced through and rammed the abyssal giant mouth, pushing it away and even using that force to shove the Infinite back toward the cliff below.

Lin suddenly turned to see Ding Junyi’s eyes glowing with a faint green light. The blood vine had somehow grown out from outside the Infinite’s cabin.

There was no time to think about what had happened. Lin acted decisively.

“Director Ding, now!”

Ding Junyi controlled the blood vine with her left hand and extended a slender green vine into the Silver Dragon Ten Thousand Mistakes’ cultivation pod with her right, gently plucking the blooming flower.

Puff!

In an instant, everyone on the Infinite and the submarine seemed to feel the boiling seawater noise vanish simultaneously, replaced by a faint bubbling pop in their ears.
