Doomsday Bunker Upgrade Chapter 577: The line of defense retreats

Finally, the senior management approved the application for the use of tactical nuclear bombs, intending to use an air-launched missile to drive a tactical nuclear bomb into the tunnels that appeared on Honghu Lake, and then use a nuclear explosion to destroy all tunnels in the entire lake area.

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

Aliens want to invade again unless they can hollow out the bottom of Hong Lake once more.

At the same time, traces of alien biological invasion have also been found in other areas. According to the detected signs of alien biological activity, they have penetrated into the surrounding of Dongting Lake, and the entire active area has covered more than half of the ancient Yunmengze's area.

Even Xingcheng, the capital of Hunan Province, and the three towns, the capital of Hubei Province, two important cities have successively discovered signs of underground extraterrestrial biological activity, causing the two places to fall into a considerable degree of tension and precaution.

And several other cities in the Dongting Lake area have also successively discovered tunnels excavated by underground alien creatures, and some cities have directly turned into new war zones.

Under such circumstances, the top management had to make a decision to withdraw the troops.

"Let the troops retreat and let go of the defense line?" Chen Xin was quite incomprehensible, and asked the general in the headquarters.

They just received the decision from the top management to let the troops retreat. Chen Xin was shocked by this order. He didn't understand why the upper management chose to choose. The retreat of the troops undoubtedly means that the way is opened for alien creatures. , so that it can drive straight to other surrounding cities, which will undoubtedly cause huge losses to the surrounding cities.

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

However, Chen Xin didn't understand, as the general in command was more thorough than him, he explained to Chen Xin: "Academician Chen, it's not that the country has to give up, but we have to retreat now and readjust the defense line. "

While speaking, the general adjusted 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 the two cities around Dongting Lake, Hunan and Hubei. An important economic and industrial city in the province, once invaded by alien creatures, will suffer great losses!

The country's retreat of the defense line is also to adjust the defense and focus on defending these important big cities. Otherwise, if these cities are lost, not only will a considerable part of the industrial production capacity be lost, but a large number of people will be affected, which will affect the country. very large. "

After hearing the general's explanation, Chen Xin could understand a little bit, but he still frowned and asked: "But once the defense line retreats, the range we need to defend will expand, with the current strength of the troops. , can't completely block these alien creatures?

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

Chen Xin's concerns are not unreasonable. The terrifying breeding ability of alien creatures will inevitably spread to other regions frantically once it spreads. At that time, it is not one region that needs to be defended, but most of the country. .

"The problem is that even if we continue to defend the line of defense, with the current expansion method of alien creatures, we can't completely block their expansion!" The city said: "These cities are all behind the defense line. It stands to reason that these cities cannot be invaded if we block the frontal invasion of alien creatures, but traces of alien biological activity are still detected now. .

Academician Chen, it's not that we want to withdraw now! Instead, we have to withdraw. If we don’t call our troops back, once the alien creatures break through these cities like Honghu Lake, do you think we will put nuclear bombs in the city, or will we evacuate people to other places like this city? "

The general's remarks made Chen Xin feel helpless for a while. At this time, he could not wait to come up with some big killer immediately, and he could kill all these alien creatures at once.

The reality is that he can't.

Although he can create powerful bombs or other destructive weapons, once that kind of thing is used, it will not be able to completely kill all alien creatures, and the damage it will cause will be quite serious. , and the consequences will be borne by human beings themselves.

Chen Xin would not have chosen to solve the problem in such an extreme way if he hadn't come to a situation where he had no choice in the end.

Until things are at their worst, it is obvious that this method, which may have huge sequelae, is not used in any way.

But if it is another way, Chen Xin has no clue or can't ensure that all alien creatures can be killed.

After all, the breeding speed of these alien creatures is too exaggerated, and they are all hiding in the ground. If you can't kill all the mothers and embryos once and for all, and prevent them from continuing to breed, they will not be called alien creatures. threat eradicated.

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

So Chen Xin must ensure that the threat of alien creatures can be eradicated once and for all, even if they cannot exterminate their populations ~IndoMTL.com~ to eliminate their threat to humanity.

"It would be great if there was a way to kill them all at once. Now even if you throw a nuclear bomb, you can't guarantee to kill them all." Chen Xin hammered the table very unwillingly, with a very serious expression on his face. Gritting his teeth, he hated his inability to do anything about this.

The general couldn't comfort him at all but shook his head, called the staff on the side, and started arranging the retreat of the defense line.

After all, it is the defense line surrounding the entire Dongting Lake area. Where to retreat, where to continue to defend, where to retreat first, where to retreat, and where to retreat after retreating...

All kinds of problems need the generals and staff to coordinate and control. There are so many things to do, and there is really no time to comfort Chen Xin.

And Chen Xin's side is not at the point where he needs to be comforted. After venting his grievance a little, Chen Xin regained his strength, left the headquarters, and walked towards the biological research room. He now urgently wants to Get biologists' research data on alien creatures, and find out how to deal with these alien creatures from these data.
