Even the strongest enemy can do nothing to them... Who can harm the undead who are already dead?

Even if they are completely dispersed, as long as those twisted Spiritual Qi are not purified, the shattered and tattered bones will still spontaneously form into a bloodthirsty monster again.

The only thing they fear is sunlight.

Therefore, they are called Night Demons.

In fact, the appearance of these Night Demons has alleviated the pressure on humanity to the maximum extent. They played an indispensable role in helping humans survive the most difficult initial period.

Although Night Demons are impartial, whether it is humans or mysterious races of the heavens, both are their targets for harm and devouring.

Yet, without a doubt, for humans who possess natural barriers, the mysterious races of the heavens attempting to siege are more troubled by these Night Demons.

For them, the only way to avoid alerting these Night Demons is to fly through the sky.

But the problem is that on the territory of the Empire, the Qisha Legion has already planted Magnetic Storm Coils in various places, making it highly likely for warships to get attracted to the ground and unable to take off.

Nuclear bombs, however, are no longer deployed.

After all, this is our land. The previous nuclear explosion by the Empire has already caused irreparable damage to Blue Star.

But many of the weapons that once made a name for themselves among the Chi Yu mysterious clan were retrofitted by Xu Lingjun and deployed within the Empire.

Plus, the appearance of Night Demons prevents them from fighting continuously day and night...

The invaders, obviously on enemy territory, clearly have already established a foothold.

Yet this battle is truly awkward, completely constrained.

As for these Night Demons, though unconscious, they have, in a certain sense, helped humans resist the mysterious races of the heavens...

Xu Lingjun naturally looks upon it with favor.

They are passively defending, and although they can’t say they are unaffected by these Night Demons, the impact is undoubtedly smaller than that on the mysterious races of the heavens. Moreover, during the day, they are not hindered in setting up Magnetic Storm Coils and other weapons everywhere.

When daylight arrives the next day.

Xu Lingjun goes to the border research institute.

To equip the warriors with the most advanced weapons as soon as possible, the Zhanzheng Academy set up a branch here, with Wang Qingya serving as the main research mentor, specifically in charge of researching the many magical theoretical weapons proposed by Xu Lingjun.

In recent times, he has assigned many powerful weapons, naturally paying attention to their progress.

Especially one of the weapons, which caught his attention immensely... If successful, without a doubt, reclaiming the Desperate Great Wall should not be a big problem.

At the same time. 𝗳𝚛𝗲𝕖𝚠𝚎𝚋𝗻𝗼𝕧𝗲𝐥.𝚌𝚘𝐦

Desperate Great Wall.

Once one of Blue Star’s three pillars, now, has completely fallen into the hands of the enemy.

After two years of modification, those defensive lines that once gave humans infinite security and full of technological splendor have now been fully transformed, with all the weapons aimed squarely at Blue Star...

Each cannon, ready to launch at any time, flashes with a cold metallic luster, along with the Satellite Cannons and antimatter bombs, all prepared to attack Blue Star at any moment!

These weapons look as if a demon is baring its claws and fangs, opening its mouth towards Blue Star, ready to pounce at any moment.

Unfortunately, these powerful weapons cannot actually be used against Blue Star.

Otherwise...

Even though Blue Star may struggle to resist the bombardment from the Cosmos, all the sacrifices made would not be only for a lifeless star, right?

Therefore, the Desperate Great Wall, plays more of a role in surveillance and as a vanguard.

Especially now, with various race leaders of the mysterious races of the heavens coming to campaign, gathering on this Desperate Great Wall.

By occupying this place... they can stand invincible.

On this morning.

At the first light of dawn, these leaders and chiefs of the various races, who had not slept all night, gathered together.

The Iron Wing Clan, Seyin Clan, Flame Race, and Silicon Based Clan, the first batch of mysterious races of the heavens to invade Blue Star, gathered together.

Led by the young leader of the Silicon Based Clan, Silicon Element.

In fact, most of the mysterious races of the heavens still develop by racial division. Although technologically advanced, they have no national boundaries, still divided by species.

Or, like the Great Xia, clearly the same race, yet divided into different nations, internally governing separately and fighting independently, which they find even more perplexing...

In the eyes of these mysterious races of the heavens, the truly correct approach is to concentrate the internal power of their race to respond fully to crises from the Cosmos.

Conflict should not arise from internal strife.

Our home is already fragile and can’t withstand harsh treatment.

Therefore, Silicon Element, although young.

But now that his father is seriously injured, without a doubt, he is the Master of Silicon, or the Young Master of Silicon.

"Yesterday’s night raid failed."

Silicon Element said heavily, "But it wasn’t fruitless. At least, we have indeed discovered that the enemy, besides the technological detection system, also has another type of defense detection system. No matter how we secretly attack, we cannot escape their surveillance. A surprise attack is meaningless to them."

His words were spoken with confidence.

During this time, as the flames of war escalated...
