Doomsday Bunker Upgrade

In the end, the high-level officials approved the application for the use of tactical nuclear bombs, intending to use air-launched missiles to shoot a tactical nuclear bomb into the tunnels that appeared on Honghu Lake, and then use nuclear explosions to destroy all the tunnels in the entire lake area.

According to calculations, the impact of the nuclear explosion will destroy most of the passages at the bottom of the lake, and the backflow of the melted lake water will completely seal off the passages that may still exist after cooling, which is enough to seal the passages from the bottom of the Honghu Lake in a short period of time. threat.

Aliens want to invade again, unless they can hollow out the ground of Honghu Lake one more time.

At the same time, traces of alien biological invasions have been found in other areas. According to the signs of alien biological activities detected so far, they have penetrated into the surrounding area of ​​Dongting Lake, and the entire activity area has covered more than half of the ancient Yunmengze. area.

Even Star City and Three Towns, two important cities, have successively discovered signs of underground alien biological activities, which has plunged the two places into a considerable degree of tension and preparedness.

In several other cities, tunnels dug by underground alien creatures have also been discovered one after another, and some cities have even directly become new war zones.

Under such circumstances, the high-level had to make a decision to let the troops retreat.

"Let the troops retreat and let go of the line of defense?" Chen Xin didn't understand this, and asked the headquarters.

They had just received the decision from the higher-ups to let the troops retreat. This order shocked Chen Xin a lot. He couldn't understand why the higher-ups had to choose. The retreat of the troops undoubtedly meant that the way was opened for alien creatures to let other It can drive straight to other surrounding cities, which will undoubtedly cause huge losses to the surrounding cities.

Although it was said that alien creatures had spread from the ground to the surrounding cities along the groundwater layer, in Chen Xin's view, this was still not a reason to abandon the existing defense line.

However, Chen Xin didn't understand. As a commander, he saw it more thoroughly than him. He explained to Chen Xin: "Academician Chen, it's not that the country wants to give up, but that we have to retreat now and readjust the defense line."

While speaking, he pulled out the map, pointed to the major cities around Dongting Lake that had been marked in red on the map, and said helplessly to Chen Xin: "These cities are important economic centers of Hunan and Hubei provinces around Dongting Lake. , Industrial cities, once invaded by alien creatures, the losses will be huge!

The reason why the state retreated the line of defense is to adjust the defense and focus on defending these important cities. Otherwise, if these cities are lost, not only will a considerable part of the industrial production capacity be lost, but also a large number of people will be affected, which will have a great impact on the country. "

Hearing such an explanation, Chen Xin understood a little bit, but he still frowned and asked, "But once the line of defense retreats, the area we need to defend will expand. With the current strength, we can't do it." Completely block these alien creatures, right?

Once they cross the line of defense, at the speed of reproduction of these alien creatures, they will quickly expand, and then what can we do to prevent their invasion? "

Chen Xin's worries are not unreasonable. Once the terrifying reproductive ability of alien creatures spreads, it will inevitably spread to other regions. At that time, it will not be a region that needs to be defended, but most regions of the country.

"The problem is that even if we continue to stick to the defense line, with the current expansion method of alien creatures, we can't completely block their expansion!" Can't help showing a wry smile, pointing to the cities marked in red on the map and said: "These cities are behind the line of defense. It stands to reason that these cities cannot be invaded if we block the frontal invasion of alien creatures, but traces of alien activities are still detected.

Academician Chen, it's not that we want to withdraw now! Instead, we have to withdraw. If the troops are not brought back, once alien creatures break through these cities like they broke through Honghu Lake, do you think we will drop nuclear bombs in the cities, or withdraw people to other places like this city? "

What he said made Chen Xin feel a little helpless. He wished he could make some big killer right now, and kill all these alien creatures in one fell swoop.

But the reality is that he can't do it.

Although he can create powerful bombs or other destructive weapons, once that kind of thing is used, let alone whether it can completely kill all alien creatures, the damage it will cause will be quite serious, so The consequences will also be borne by humans themselves.

Chen Xin would not have chosen to use such an extreme method to solve the problem if it hadn't come to a situation where there was no other way.

Before things get to the worst situation, it is obvious that this method, which may have huge sequelae, cannot be used anyway.

But if it was another method, Chen Xin had no idea or could not guarantee that all alien creatures could be wiped out.

After all, the breeding speed of these extraterrestrial creatures is too exaggerated, and they are all hiding underground. If you can't kill all the mothers and embryos once and for all, and prevent them from continuing to reproduce, it can't be called eradicating the threat of alien creatures .

This is undoubtedly unacceptable. After all, even if the vast majority of alien organisms can be exterminated in a short period of time, with their reproduction speed, they will have their current scale or even exaggerate in three or two years.

Therefore, Chen Xin must ensure that the threat of alien creatures can be eradicated once and for all. Even if their population cannot be exterminated, their threat to human beings must be eliminated.

"It would be nice if there was a way to kill them all at once. Now even if we throw a nuclear bomb, we can't guarantee to kill them all." Chen Xin hammered the table unwillingly, with a gritted teeth expression on his face. own inability to do anything about it.

There was nothing to comfort him about this. He could only shake his head, call the staff at the side, and start arranging for the defense line to retreat.

After all, it is the defense line that surrounds the entire Dongting Lake area. Where to retreat, where to continue to hold on, where to retreat first, where to retreat, and where to retreat after retreat...

All kinds of problems need to be coordinated and controlled with the staff. There are so many things to do, and there is really no time to comfort Chen Xin.

And Chen Xin didn't need to be comforted. After venting his grievances a little, Chen Xin regained his strength, left the headquarters, and walked towards the biological research room. He is now eager to get the biological Scientists study the data of extraterrestrial creatures, and find ways to deal with these extraterrestrial creatures from these materials.
