Doomsday Bunker Upgrade

The evacuation work has been going on in an intense and orderly manner. Although there are hundreds of thousands of people to be evacuated, fortunately the city government has a pre-prepared evacuation plan, so far there have been no problems.

The military also relied on planting bombs in the evacuated shelters, and the air force used methods such as ground-penetrating bombs to delay the invasion of the city by alien creatures as much as possible.

Overall, the current situation has finally stabilized.

Although the city still has to give up, the fierce confrontation between humans and alien creatures has gradually turned into a delay.

On the human side, there is no effective containment method for the underground offensive of alien creatures, so they have to abandon the cities along the Dongting Lake, while on the part of alien creatures, it is because of the huge casualties.

Unlike the human army, which relied on advanced equipment and did not suffer too many casualties, but consumed a lot of ammunition, a large number of individuals were wiped out in terms of alien creatures.

Even though the social structure of this alien creature is similar to that of a swarm, and the bottom-level combat offspring and worker ant offspring are all cannon fodder and consumables, they were mass-killed by carpet bombing by humans before, and continued to kill on a large scale after that , or let the alien creatures consume a lot of troops.

They have successfully turned them from being as raging as a flood to being somewhat powerless now.

But that doesn't mean aliens are dead.

Although the loss of a large number of combat offspring and worker ant offspring has weakened the overall population of the colony, the mothers and hatcheries hidden deep underground have not been damaged. The replenishment of troops is just a matter of a few more rounds of incubation in the hatchery.

Especially when these alien creatures realize that they have lost a large number of individuals, and let the mother and the hatchery start to catalyze the hatching speed of the daughters, their replenishment speed will be faster.

Although the hatching speed of the catalytic daughter body will greatly shorten the life span of the daughter body, and even affect the physical fitness, it can replenish the number of daughter bodies in a short period of time.

Since they are all thrown directly into the battlefield and cannot survive for three minutes, there is no difference between using cheap instant offspring and using more expensive standard offspring, isn't there?

Although it is just a group of alien creatures, there is a highly intelligent individual in their group. Even without human intelligence, they can quickly learn this principle on the battlefield.

However, while continuing to add oil to the battlefield, the leader of the ethnic group is gradually changing his strategy, and began to recover the bodies of the dead offspring from the battlefield to recover biomass.

For this kind of alien creature, the battle is actually a quality war. As long as there is enough biomass, the group can hatch a steady stream of offspring and send them to the battlefield until the opponent is completely submerged.

After all, for civilizations that are still on the surface of the planet, fighting quality wars is no match for creatures like them that can have an endless supply.

In the memory inherited in the group genes, this group has invaded many living planets, relying on their amazing reproductive ability and powerful combat effectiveness, and finally submerged the entire planet with offspring like a vast ocean.

It's just that there seems to be something wrong with the planet they chose this time. Not only is the entire planet covered with ice and snow, but the entire planet's surface also lacks organic matter and biomass. As a result, the population can only convert energy by absorbing geothermal heat, which makes their expansion speed slowed down. greatly weakened.

In fact, if this group of alien creatures invaded the Blue Star before the disaster, relying on their strong reproductive ability, the outbreak of biological invasion at this moment is not just a Dongting Lake area, but the entire Yangtze River Basin.

Humans don't know this at this time, but with further research on alien creatures, they will know this sooner or later.

As for how to completely wipe out these alien creatures and expel them from the blue star, even Chen Xin still has no idea at this time.

Although it is not impossible to completely exterminate these creatures, Chen Xin at this time is still entangled in the matter at hand, and cannot spare time and thoughts to think about how to exterminate these invading alien creatures.

While organizing the evacuation of cities around Dongting Lake, high-level officials are also seriously considering the possibility of using nuclear weapons in the lake area.

After all, after the evacuation of the people around the city, the use of weapons of mass destruction such as nuclear weapons will be less restricted and restricted, allowing high-level officials to consider using them.

It's just that the current high-level officials are not sure whether nuclear weapons can effectively kill alien creatures. In addition, considering the possible impact of using nuclear weapons on their own land, although the high-level leaders have such an idea, they are only preparing to act as a last resort. The final scenario used.

Right now, the top management still hopes to rely on the military's conventional force to deal with these alien creatures emerging from the ground.

It's just that although the military can stabilize its defense line on the frontal battlefield, if it is said that it can effectively eliminate these alien creatures, I am afraid that the military cannot do it right now.

After knowing that most of the people in the rear city had completed the evacuation work, the military did not adopt hard-top tactics anymore, and began to gradually withdraw the defense line, reducing the intensity of shelling and bombing, and reducing the consumption of ammunition.

Sustaining high-intensity air force bombing and shelling can indeed effectively kill alien creatures, but the consumption of ammunition behind it is also amazing.

Although people often complain that the Yan Kingdom has too many ammunition reserves, and a large amount of expired ammunition is destroyed every year, there is still a logistical transportation and supply process between the expired ammunition in the warehouse and the consumption on the battlefield.

It's really cool to bomb FMD on the front line, but the logistics also need to be scolded.

Under normal circumstances, the more exciting the bombing on the front line, the louder the voice of scolding in the logistics will be, and the two are directly proportional.

After all, every bullet used on the front line needs to be transported up by logistics.

Even though Yan Kingdom has a fairly complete and powerful logistics system, there is still a limit to the amount of ammunition that can be sent to the battlefield and the front line in such a sudden large-scale war.

After such a long period of high-intensity fighting, the ammunition carried by the troops on the defense line has basically been exhausted, and the ammunition sent by the logistics has also consumed a lot. On the whole, if we continue to maintain the previous high-intensity firepower, The consumption of ammunition can't keep up.

After all, most of the people in the city have been evacuated now, and the corresponding ammunition supplies transported up have also been affected to a certain extent.

Therefore, after evaluating the situation on the battlefield, the military made the decision to gradually retreat.
