The zombie arm that was thrown away by Yu Lin fell at his feet. The stump of the arm, which had been separated from his master's main body, had dense reddish-brown protrusions on its surface, and these protrusions were rapidly bulging and expanding at a speed visible to the naked eye.

In just the blink of an eye, the surface of the entire zombie's arm has become like the skin of a toad, covered with dense bulges, and it looks extremely disgusting. Not only that, but the zombie stump arm actually wriggled like a maggot, and there was a gurgling sound of boiling liquid from inside it.

Suddenly, the zombie stump trembled strangely, and the entire stump rapidly expanded, like an inflated balloon, and the sound of liquid boiling from inside became violent.

At this moment, Yu Lin's heart was shocked, and an inexplicable sense of danger followed. The moment he felt the threat, his body was no longer under the control of Lin Siwei, and he reacted on his own, and kicked the ground with his legs, and the whole person took advantage of this force to fly straight towards the conference room.

At the same time as his body entered the door of the conference room, a low popping sound came from behind Yu Lin, followed by an unusually unpleasant stench. It was only then that Yu Lin's body returned to the control of his mind.

The situation of uncontrolled body has often happened these days, and Yu Lin is no longer surprised. His bodily functions have been comprehensively strengthened, resulting in his thinking often not keeping up with his body's movements, especially when encountering danger, often because his brain has not yet reflected, and his body has instinctively made strain. After these days of targeted training, this situation is gradually decreasing, and Yu Lin calls this situation a state of self-protection.

A carp bounced off the ground, Yu Lin walked quickly to the door of the conference room, he wanted to see what kind of danger could make his body enter a state of self-protection, you know, even if he faced hundreds of zombies in the corridor just now, his body still did not enter this state, but a zombie stump arm threatened his life.

The moment he walked out of the door of the conference room, Yu Lin was completely stunned, the wall outside the door, the ground seemed to have been corroded by strong acid, and a large number of potholes appeared, especially the place where the broken arm fell just now, it was corroded out of a pit with a diameter of about one meter and a depth of more than ten centimeters, and those places that had been corroded were still emitting bursts of pale green smoke, and the disgusting stench came from this pale green smoke.

Seeing the corroded potholes, Yu Lin's heart was afraid for a while, if it wasn't for his body entering a state of self-protection just now, he didn't dare to imagine what he would become after being affected by the explosion of the zombie stump just now, he didn't believe that his skin was harder than the cement floor, and it was more corrosion-resistant.

However, Yu Lin immediately realized a problem. He has killed a lot of zombies, but it is the first time he has encountered zombies whose corpses can explode and have their own corrosive attacks, which can be explained as the owner of this zombie stump arm is a mutated zombie!

Thinking of this, Yu Lin immediately began to look for the zombie whose arm was cut off by himself in the corpse group in the corridor, Yu Lin has always suspected that the types of mutant zombies are definitely not only iron fist zombies, there must be other mutant zombies, and this discovery also fully confirmed Yu Lin's thoughts.

After a short time, Yu Lin found this zombie with a broken arm hidden in the third row of the corpse group, unlike the shriveled bodies of other ordinary zombies, this zombie was like a corpse soaked in water for a long time, with pale skin and swollen body, especially the belly of this zombie, which was like a pregnant woman, bulging high.

At the first glance of the zombie, Yu Lin was sure that this zombie was definitely a mutated zombie, because this big-bellied zombie was hiding in the group of corpses and watching Yu Lin, and the zombie's eyes looking at Yu Lin were full of anger and killing intent, not as sluggish and indifferent as other ordinary zombies.

Where there is emotion, there is thought, and where there is thought, there is wisdom, and the performance of the big-bellied zombie also fully proves that the mutant zombie has wisdom.

This is Yu Lin's first close contact with mutant zombies, the last time he found the Iron Fist Zombie, because Yu Lin was hiding in the car and observing from a distance, he only saw the general situation of the Iron Fist Zombie, and did not really grasp the true strength of the Iron Fist Zombie.

This encounter with a new type of mutant zombie is a great opportunity for Yu Lin to understand the mutant zombies, as the saying goes, knowing oneself and knowing the other can win a hundred battles, Yu Lin now knows too little about mutant zombies, he wants to seize this opportunity to understand the ability of mutant zombies more clearly. Besides, he wanted to see how powerful he was now.

The big-bellied mutated zombies are mixed in with the zombie group at this time. From the perspective of mutant zombies, the big-bellied zombie has no other changes except for the bulging belly and the puffiness of the body, and people who see this kind of zombie for the first time can easily mistake it for an ordinary zombie.

However, Yu Lin, who saw the power of the explosion of the zombie arm just now, did not dare to underestimate this mutated zombie at all, Yu Lin even guessed that if this zombie was killed, it might burst as a whole, and the power of a stump arm was already so terrifying, so what would be the effect of the explosion of the whole zombie?

Yu Lin couldn't estimate the power of the big-bellied zombie after it exploded, but Yu Lin would soon know, because he didn't plan to let go of this mutated zombie, as long as he killed all the zombies in the corridor, he would naturally be able to test out what the destructive power of the big-bellied zombie was.

Yu Lin swung his knife again and rushed into the corpse group, but because he knew that there was a mutated zombie in the corpse group, Yu Lin was extremely careful, he quickly detoured between the corpse group and the conference room, every time he approached the corpse group, he just quickly killed the first few zombies, and immediately retreated to the door of the conference room.

Although this kind of attack greatly reduces the progress of killing zombies, and at the same time consumes more physical strength, but it is the safest method, Yu Lin suspects that the big-bellied zombie will have other attack methods, he doesn't believe that this mutant zombie only has the attack method of ** bomb.

Although the efficiency of killing zombies is not very high in such a roundabout attack, after all, Yu Lin's physical fitness is very strong now, and after a few minutes, he has still killed dozens of ordinary zombies.

While killing these ordinary zombies, Yu Lin also discovered a problem. No matter how Yu Lin cleaned up the zombies in the front row, there would be ordinary zombies to fill the vacancy immediately, but the position of the mutated zombie had never changed.

Moreover, Yu Lin also noticed that whenever he was about to kill the ordinary zombies that were blocking the mutant big-bellied zombies, the mutated zombies would immediately let out an extremely sharp hissing sound, and then the ordinary zombies behind him would rush forward and block in front of him.

What does this mean, this shows that this big-bellied mutant zombie is controlling ordinary zombies! Does this also indicate that all mutant zombies can control ordinary zombies? This discovery shocked Yu Lin.

If Yu Lin's guess is correct, then it indicates that there is not only an evolutionary group among the zombies, but also an intelligent group with a strict hierarchy, if that is the case, then, with the huge number of zombie groups, the hope of humans to regain control of this world will become extremely slim.

In fact, Yu Lin doesn't care what the world will be like in the future, it doesn't have much to do with him, he is not a savior, and he doesn't have the ability and obligation to save the world, he just wants to survive in this apocalyptic world with his lover and friends.

In order to achieve this goal, he must also learn as much as possible about the zombies and defeat the zombies, only in this way can he and his lover and partners survive in this apocalyptic world together, which is the goal he is now striving for.

Yu Lin continued to kill ordinary zombies while observing the situation of the big-bellied mutant zombies. After a period of careful observation, Yu Lin found that there was a limit to the number of ordinary zombies controlled by the big-bellied mutant zombies, and the number of ordinary zombies blocking in front of the mutant zombies did not exceed twenty each time, that is to say, this mutant zombie could only control twenty ordinary zombies at one time.

However, this big-bellied mutant zombie is also very cunning, he always hides his body in the corpse group, as long as the ordinary zombies controlled by him are eliminated by Yu Lin, the next batch of ordinary zombies will be controlled by him and blocked in front of him.

In this narrow corridor, the big-bellied mutant zombies have taken advantage of the location and people, and if Yu Lin wants to kill him, he must kill all the hundreds of zombies in the corridor.

However, after a period of fierce fighting, Yu Lin also found that the big-bellied mutant zombies, except for the initial body explosion attack, did not use other attack methods, and Yu Lin simply did not fear, and began to slaughter ordinary zombies with one mind.

That's right, slaughter. If it was before, Yu Lin would definitely not be able to fight against such a large number of ordinary zombies, even if he used the zombies' fear of sunlight, his physical strength would not be able to support him in such a high-intensity battle.

However, through the battle just now, Yu Lin found that he still didn't fully understand his own abilities. According to what he knew, his physical indicators in all aspects had only increased by 1 to 2 times, but he had ignored his recovery ability, and he could recover his strength on his own in battle, which greatly increased his combat endurance.

At this time, Yu Lin had already engaged in a high-intensity hand-to-hand fight with the zombies in the corridor for twenty minutes, but he did not feel the slightest lack of physical exhaustion, except for the feeling of heat and dryness in his body due to long-term vigorous exercise, he didn't even feel uncomfortable breathing. Such a discovery surprised and delighted Yu Lin.

In fact, in a sense, Yu Lin can no longer be called a human being, although the CR project is a human gene enhancement plan, but after changing the gene sequence, human beings have essentially become another creature, just like zombies, a new species after human mutation.
