The evacuation work has been carried out in a tense and orderly manner. Although there are more than 100000 people to be evacuated, fortunately, the municipal government has a pre prepared evacuation plan, so far there has been no problem.

The military also relies on planting bombs in the evacuated shelters, and the air force uses ground penetrating bombs and other means to delay the alien invasion of the city as much as possible.

On the whole, the current situation has finally stabilized.

Although cities still have to give up, the fierce battle between humans and alien creatures has gradually become a drag on time.

On the human side, there is no effective means to curb the underground offensive of alien creatures, so we have to give up the cities along Dongting Lake. On the other hand, the alien creatures are due to the huge casualties.

Unlike the human side, where the armed forces rely on advanced equipment and do not suffer too much casualties, but consume a lot of ammunition, a large number of individuals have been wiped out in terms of alien creatures.

Even though the social structure of this alien creature is similar to that of insect swarm, and the combat progeny and worker ant progeny at the bottom belong to cannon fodder and consumables, they have been heavily damaged by human carpet bombing before, and continued mass destruction after that, which still makes the alien creature consume a lot of troops.

The success makes them from the original like flood surge, become now some successor powerless appearance.

But that doesn't mean alien life is not going to work.

Although the loss of a large number of combat and worker ant progenies has weakened the population as a whole, the underground mother and hatchery have not been damaged. For the alien species, it is only the hatchery that needs to hatch a few more rounds if they want to replenish their forces.

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

Although the incubation rate of the catalytic progeny will greatly shorten the life span of the progeny, and even affect the physical quality, it can replenish the number of the progeny in a short time.

Since they are all thrown directly into the battlefield and live for less than three minutes, there is no difference between using cheap instant progeny and using more expensive standard progeny, right?

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

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

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

After all, for civilizations that are still on the planet's surface, fighting mass wars is no match for their endless stream of creatures.

In the memory inherited from the ethnic group's genes, this ethnic group has invaded many living planets, relying on their amazing reproductive capacity and powerful combat effectiveness, and finally drowned the whole planet with offspring like a sea.

But this time, there seems to be something wrong with the planet they chose. Not only is the whole planet covered with ice and snow, but the whole planet is also short of organic matter and biomass. As a result, the population can only convert energy by absorbing geothermal energy, which greatly weakens their expansion speed.

In fact, if this group of alien creatures invades the blue star before the disaster, relying on their strong reproductive capacity, the biological invasion at this moment is not just a Dongting Lake area, but the entire Yangtze River Basin.

This is not known to humans at this time, but with the further study of extraterrestrial organisms, they will know this sooner or later.

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

Although it's not that there is no way to completely exterminate these creatures, Chen Xin is still entangled with the things at hand at this time, and can't spare time and think about how to exterminate these invasive 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, so that the high-level can consider using them.

However, at present, the high-level officials are not sure whether nuclear weapons can effectively kill and kill alien creatures. Considering the possible impact of using nuclear weapons in their own territory, the high-level officials have such an idea, but they are only prepared to use it as a last resort.

At present, the high level still hopes to rely on the conventional military force to solve the problem of these alien creatures emerging from the ground.

It's just that although the military can stabilize its defense line on the frontal battlefield, it can't effectively eliminate these alien creatures now.

After getting the information that most of the people in the rear cities have completed the evacuation work, the military has no longer adopted the tactics of hard top, and began to gradually withdraw the defense line, reduce the intensity of shelling and bombing, and reduce the consumption of ammunition.

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

Although many people make complaints about too many ammunition reserves, they have to destroy a lot of expired ammunition every year, but there is a logistic transportation replenishment process between the warehouse expired and the battlefield consumption.

It's really cool to blow up TMD in the front line, but the logistics is also a curse.

Under normal circumstances, the better the front-line bombing, the louder the voice of the logistics curse, which is proportional to the two.

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

Even though the country has a fairly perfect and powerful logistics system, there is still a limit to the amount of ammunition that can be sent to the battlefield and 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 used up, 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 will not be able to keep up.

After all, most of the people in the city have evacuated, and the corresponding ammunition supply has also been affected.

So the military decided to withdraw gradually after evaluating the situation on the battlefield.
