Every time a creature migrates, it brings some scars to the fallen city. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Originally rich and prosperous, with a large population, and ranking high in the country, the first-tier cities are now a dead city, a corpse city, because of the arrival of an apocalyptic disaster.

Zombies are everywhere in the city, playing the role of hunters, wandering through the streets and corners of the city, looking for prey.

Once they find a trace of a survivor, they will pounce on them in a frenzy and tear them to shreds.

But now, more than three months have passed since the disaster, and the seasonal climate change has begun to enter the winter, the temperature has dropped sharply, and the cold has begun to hit.

The big city where there should have been millions of zombies rampant, after many diverts and spread outward, the attack of mutant creatures, and the mutants led the corpses to move away one after another, but the number of zombies in this big city has dropped sharply by four or five percent.

Don't think this is a good phenomenon, the decrease in the number of zombies does not mean that it will be safer, but it will be a more dangerous environment brewing.

Those mutants are intelligent, and they are constantly evolving like those mutant creatures, and since the catastrophe struck, all the creatures on the entire earth have passively entered a cruel race for survival and evolution.

In this race between existential crisis and evolutionary crisis, human beings have not found the right direction for evolutionary development, and have quickly fallen to the bottom of the food chain.

Since human beings have been reduced to the bottom of the food chain, as prey to be slaughtered and preyed, the larger the city, the more populous the city, the number of survivors will be quite large, and it should be a paradise for those zombie activities.

But now, even the mutants are starting to leave the city with their corpses and travel to other places, which shows that the potential danger in the city is growing.

Rapid changes in the environment will wary mutants who are intelligent and alert.

The reason why they would abandon such a large urban environment that is conducive to their evolution and development must be that there is something wrong with the city, which poses a great threat to their survival, so they will move away on a large scale.

Perhaps Xu Shenzhou was in it before, and the scope of observation and detection was limited, and there were certain limitations, so he did not find the reason.

But now, through Xu Shenzhou's meticulous observation of this wave of biological migration laws, he feels that he has found the answer from it.

Nuclear explosions and radiation may be just one of the factors that are not important and critical, and it is estimated that they are only the triggers for the large-scale migration of hidden organisms in cities.

The real main reason is probably the mutated plants scattered in the city that are very inconspicuous and look ordinary, but there are murderous motives hidden in them.

Xu Shenzhou felt that the most obvious thing was that after the nuclear explosion, although the nuclear radiation had not spread rapidly and affected the surrounding areas of the provincial capital, those mutated plants were extremely active.

At the same time, there was a smell in the air that made people feel like sulfur, and it was the smell that caused the mutated plants to start a round of madness again.

And it is those mutated plants that do not seem to be obvious, but they are in a state of crazy growth, and the green distributed throughout the city has almost covered a large area.

After looking at other places, Xu Shenzhou came back to look at Du Garden, and he would find that there were some subtle changes in Du Garden that could not be seen on the surface.

Now the plants in the Du Garden have spread and spread out, and at the same time, they have also wrapped around the villa complex where the camp is located, forming a green encirclement.

It was precisely because of this encirclement that some creatures were afraid to prevent the two groups of mass-migrating biota from wreaking havoc on this lucky refuge camp.

Xu Shenzhou knew how the radiation from the nuclear explosion would affect those mutated plants, but I was afraid that the radiation should also have a beneficial side to those plants.

Because the nuclear explosion only happened for a few hours, the breath that spread in the air made the mutated plants appear to be extremely active, and if the radiation spread to the vicinity, it is estimated that those plants will grow even more wildly.

In the garden, many buildings have been completely covered with plants, and the outline of the building itself can no longer be seen.

And the mutated plants around the hangar have covered the entire hangar, and at the same time began to extend to the top, which is the main reason why the big monster bird is ready to migrate away.

Haw!

At this time, Xu Shenzhou was interrupted by an anxious chirping of the big monster bird, so he once again focused his attention on the big monster bird.

The big monster bird seemed to have discovered Xu Shenzhou again, so it flew towards Xu Shenzhou.

Made, is there an end?

Xu Shenzhou saw the big monster bird and found him flying over again, and after scolding, he was ready to leave quickly, avoid the annoying big monster bird, and wait for her to move away.

However, this time, the big monster bird didn't seem to have the intention of attacking Xu Shenzhou, but after circling at a low altitude, it screamed a few times towards Xu Shenzhou.

After discovering this situation, Xu Shenzhou stood firm and looked a little surprised, what did the big monster bird want to do?

Lose!

At that moment, the big monster bird flapped its wings, and saw a stick-like object thrown down by her.

After Xu Shenzhou saw that thing, he was even more surprised in his heart, because what was left by the big monster bird was the sniper rifle he had lost in Du Yuan.

Ben was still thinking about finding an opportunity to go to Du Yuan to pick up the gun, but he didn't expect that the gun fell from the sky at this time and was thrown down by the big strange bird.

In order to avoid the gun falling from a high altitude and being broken, Xu Shenzhou quickly took an arrow step a few meters forward, and after seeing the landing point of the gun, when the rifle fell, he quickly reached out and caught it.

After a simple inspection, the gun was not corroded, there was no trace of damage, and it was still intact and usable, Xu Shenzhou couldn't help but feel relieved.

It's just that he began to wonder in his heart.

Ever since the mutated toad in the artificial lake was eliminated, the big monster bird first threw down a piece of crystal source that the toad had swallowed into its stomach and gave it to him, and that crystal source was the key to the gate of a confidential passage somewhere in Du Yuan.

And now, instead of attacking him again, the Great Monster Bird has returned to him the gun he had lost in the Nadu Garden, which seems to be a gesture of goodwill.

It's just that the big monster bird shows favor to himself for no reason, what is his intention?

Xu Shenzhou raised his head and stared at the big strange bird hovering in the low altitude and fell into deep thought.
