In the last days, people start an aerospace aircraft carrier

When the air return line was deployed, Su Xu was finally able to witness the scene of the city center.

Immediately, another group of enemies from the deep pit at the source of the gray mist also entered his field of vision.

Looking at the tide of monsters on the screen that densely covered every inch of the ground around the deep pit, his heart was slightly heavy.

These monsters can force mutants to migrate outward, and they will only be more brutal and fierce than mutants.

The human survivors have one more formidable enemy.

And being thousands of meters in the air may not always be stable.

Who knows what terrifying existence will come out of that deep pit.

Since there are types of these monsters that can intercept air targets, there may also be flying species.

The safest countermeasure is to find a way to fill or seal the pit.

Maybe you can try to get a nuclear bomb and throw it in?

He was deep in thought when a system prompt suddenly sounded in his head.

“Ding! Trigger the side quest [Contain the Invasion]. ”

“Mission Requirement: Destroy underground passages scattered around the world that connect unknown worlds.”

“Mission Reward: Rewards for each passage destroyed.”

Another side quest!

And the requirement is to destroy this pit.

Or use the description of the system, connect the underground passages of the unknown world.

Su Xu’s eyes froze.

The system’s mission requirements actually revealed two important pieces of information to him.

First, such deep pits are indeed not limited to Zhonghai.

Second, this pit connects to another world, most likely the gray mist and the world where these monsters come from.

This apocalypse is essentially another world’s invasion of Blue Star.

It is a pity that the system does not say how to destroy these passages, and he can only grope for it himself.

But since it is a passage to another world, landfilling will definitely not work.

It is not enough to make a lid on the surface to seal it.

Neither “Destroy” that meets the requirements of the mission will necessarily block monsters from another world.

It seems to be a more reliable means to get some nuclear bombs to blow up.

After all, a deep pit with a diameter of nearly three kilometers is not something that ordinary bombs can blow down, and even a small-yield nuclear bomb may not work.

In addition, it is necessary to consider the possibility that this passage has a self-defense mechanism similar to the wormhole in Pacific Rim.

Unfortunately, the gray material gushing out of the pit rolled up a violent air flow, making it impossible for the air-stranded nanorobots to approach.

He couldn’t get into what was going on.

Su Xu decided to bombard the inside of the pit first.

“All secondary guns lock onto the deep pit in the city center, firing a base ammunition into it!”

The Dawnhammer satellite has left its position to attack the Middle Sea and will not be activated until several hours later.

After all, in order to ensure the power of this space-based energy weapon, it is not in orbit where the previous quantum communication satellite is located.

The geostationary orbit at an altitude of nearly 36,000 kilometers is too high from the ground, and the energy attenuation of the particle beam is relatively large.

As a result, the Dawnhammer operates at much lower altitudes than in geostationary orbit.

With Su Xu’s order, the six triple auxiliary guns on the side of the space carrier slightly adjusted their pointing and locked the deep pit with the help of the stagnant return line.

Boom boom-

With a flash of fire, eighteen barrels opened fire in unison.

The stagnant loop on the ground clearly captured the shell firing into the pit, and then there was no movement.

The firing of the secondary guns did not stop, and shells were constantly pouring towards the underground passages.

When a base number of ammunition is fired, nothing changes are visible in the pit.

Gray matter and monsters are still pouring out of it.

The shelling of the space carrier is like shooting into a black hole.

Su Xu pouted: “It seems that at least ordinary attacks will not have any effect.” ”

Agent Hill, who had been silently watching, said at this time: “The monster that climbed up from the pit did not spread outside the city center. It seems that there is something that limits their range of activities. ”

“Oh?” Su Xu carefully observed for a while, “It’s true. ”

This is good news, at least the survivors in the city do not have to face this monster stronger than mutants for the time being.

“That’s the end of today’s action.” The time was approaching evening, and Su Xu was ready to leave work, “Closely monitor the city center, especially the movements of those monsters.” ”

“Tomorrow, we will go to Zhonghai University as scheduled to carry out rescue!”

From the results of current monitoring, the mutation of the deep pit does not pose a greater threat for the time being, except for making the mutant more active.

Since this is the case, there is no need to worry about it, and the rescue operation can continue.

And you have to hurry.

Otherwise, when the monsters that crawl out of the underground passage begin to spread to the periphery, not only will the rescue operation be more difficult, but the number of survivors may also usher in a wave of major reductions.

“I hope those monsters stay honestly for a little longer.” Su Xu said to himself, “Besides, it would be better if they could fight with mutants. ”

One mountain does not allow two tigers. I don’t know if these otherworldly invaders and the native mutants transformed by the gray mist of their world will fight each other.
