Then, within a few days, the number of reports skyrocketed and doubled, and city experts urgently consulted and quarantined the hospital — but it was too late. The "insane" attackers, their complexions turned gray, their muscles highly contracted and tightened, their reaction speed and strength became far greater than that of ordinary humans, and they were like wolves, in packs, easily breaking through the hospital quarantine area and rushing into the city.

At the same time, family members, patients, and medical staff who have been scratched and bitten by the first generation of infected people...... The first symptoms of madness also began to appear.

Can you imagine a day when you're walking down the street with your family and friends. You're just discussing the sensational "alien incidents" some time ago, most of them have been hunted down by the army, and the few remaining have been expelled from your city. You finally feel like you can breathe a breath of safe and free air, and you think it's all going back to its original track.

At this moment, in the calm and warm sunshine, in the noisy streets, there was a group of people like monsters, rushing out of nowhere and rushing towards you like lambs.

When you open your eyes again, you don't remember who you are.

......

It's like a drop of ink, falling into a bowl of clear water. The number of infected people is growing wildly at exponential multiples. No matter how capable a manager is, he will not be able to cope with such a rapid expansion that begins with the catastrophe of extinction from within! In just half a month, Xiangcheng almost fell.

The city is no longer the same city, and everyone's life is no longer stable and peaceful. Man-eating monsters began to hide on street corners, and more and more people disappeared, and screams and cries could often be heard at night. Those who fled the city were lost, and those who remained in the city were in a dream. Even the distance of 100 meters from home to the community convenience store has become unreachable and dangerous. The order of people's lives quickly collapsed, and panic filled the air like a fog. Here, it becomes like a dead city. People's beliefs almost collapsed.

Moreover, the human infected, who are like inferior beasts, seem to be born with the scent of their own kind, and they find those aliens in the city, and they are in the company of them, and they are at their command. The Xenomorphs not only have superpowers, but also retain intelligence, so such a team of infected people led by Xenomorphs haunt the city like the demons of hell.

After a period of loss of control and chaos, humanity finally fully understood what was happening, and the defense forces of all sides quickly assembled, all-out confrontation, and a strong counterattack. Humans and mutants are engaged in fierce snatching and fighting in every line of defense, every street, and every neighborhood in the city.

And the army that was originally stationed near Xiangcheng became the first generation of infected people because of the wounded who fought against the aliens in the early stage. Several waves of mutation broke out in the army, and the defense line almost collapsed completely. But in the end, the commanders took control of the situation strongly and decisively, and restored the army's combat effectiveness as quickly as possible.

At the same time, the xenomorph camp is not having a good time. They also had the wounded, and the mutation wave came just as suddenly. But their situation is different from that of humans, among the twelve wounded, eight of them were infected and mutated, and became the same as the aliens, with all their temperaments, six relatives who did not recognize them, and who were cruel and murderous, but they retained their intelligence, and their realms all jumped to varying degrees.

Of the remaining four wounded, two had neither mutated nor improved, and two had risen one level in their realm, but they had not mutated, and their temperament was normal, the same as before.

But the eight infected people led by Xiao Qinglong, at the very least, are also returning dogs, which is enough to become a murderous and terrifying force!

Fortunately, there is also a Li Chenglin, who is even more ferocious and terrifying than them! If it weren't for her crazy iron-blooded crit attack to repel the infected in one fell swoop, the management office of the Xiangcheng Xenomorph Alliance would be wiped out from within, just like some cities.

The human army and the xenomorph management office, which had recovered their vitality, quickly turned their heads, one bright and one dark, and returned to the city, thundering to rescue and counterattack in an all-round way.

Since then, all infected people, including xenomorphs, xenomorphs, and humans, have been referred to as "mutants". Their team, known as the "Mutant Army".

......

In the first year, only xenomorph riots broke out across the country, the xenomorph alliance secretly suppressed them, and the human authorities encircled and pursued them, and everything was still under control.

The following year, the mutation tide broke out, and a nationwide catastrophe came, with countless human casualties, xenomorphs suffered heavy setbacks, and mutants were everywhere. Every city has become a battlefield, and the battle is scorching.

Now, in its third year. The human defense line is growing stronger and more advanced. And the battle situation in each city tends to be clear and different.

Some cities have been completely occupied by mutants and become their nests, humans have disappeared, and all xenos have died in battle. For example, in Guicheng, west of Xiangcheng, it is said that Lin Day, the leader of the mutant army who has been promoted to the Great Green Dragon Realm, is entrenched there.

In some cities, the two sides are still fighting to the death, seizing land inch by inch, such as Liaocheng in Northeast China. Due to their agility, mutants are scattered throughout the city. Moreover, those who were infected in the early stage were asymptomatic and no different from normal humans. So in the city, it is difficult to use weapons of mass destruction to catch them all.

In some cities, human beings have gained absolute control, and this is the case in Xiangcheng. Several core areas of the city, as well as some important towns and villages, have been completely controlled by humans, and fences have been fenced off and safe zones have been established. Basically, humans in the safe zone have been able to return to most of their normal lives.

Outside of the safe zone, there are the Fallen Zones occupied by mutants, and the Ownerless Zones, which are completely degraded. There are both humans who have not been able to evacuate in the unclaimed zone, and mutants who roam.

Lu Weizhen's home is in the unclaimed area. However, where Li Chenglin is, he is the uncrowned king. There are almost no mutant troops in the vicinity who dare to approach, only scattered mutants with no IQ, who will occasionally haunt. The few humans hiding around her are all protected by her.

In addition, Xiangcheng's external defense line is also complete, orderly and solid, so it has almost become a refuge for people in some nearby cities to dream of reaching.

Obviously, the success of the defensive battle of Xiangcheng is inseparable from Li Chenglin. Because in the past few years, she has secretly led her subordinates to hunt and kill most of the high-level mutants. This greatly reduces the pressure on the human army.

Sometimes, forced by the situation, Li Chenglin is also unforgivable in broad daylight. Therefore, the human leaders of Xiangcheng have long known about the existence of this force. But I don't know if it's because I'm instructed by my superiors, or if I don't have time to clone myself, for the power of aliens, human beings adopt the principle of not asking or not being on the line. I don't come close to negotiate joint defense with them, and I never get embarrassed. The human army passed through this area, and it was all a detour.
