"Zhang Fan, don't worry, I will protect Xu Sulan!"

Li Yihui followed Zhang Fan and said with a smile on his face.

He could have climbed down directly from the fourth floor window, but he chose not to and took the stairs with Zhang Fan specifically, naturally to show off.

Although Li Yihui has a strong sense of justice, he is still a young man in his early twenties after all, and there is some comparison in his heart with Zhang Fan.

Especially, before, he was helpless in the face of the crawling zombies and could only escape with everyone. However, Zhang Fan survived the attack of the mutated zombie.

In addition, he went upstairs with the determination to die, but when he went up, he found that Zhang Fan was exercising leisurely. This contrast made him feel extremely unhappy.

At this moment, after finally finding an opportunity, Li Yihui naturally did not want to let it go, as if he had found a reason to be better than Zhang Fan on this track.

"There's no need to tell me, I don't care either!" Zhang Fan said calmly.

Such a calm tone made Li Yihui a little unhappy, feeling that his strength was not enough.

"You are just pretending, you must care about Xu Sulan..."

Li Yihui pretended to be profound, showing a look like I've seen through you a long time ago, and said with a smile: "You must like Xu Sulan very much, that's why you always protect her. I know people like you very well, and I don't dare to express my love.

Buried deep in my heart..."

"hehe!"

Zhang Fan sneered and did not make any further response.

Love? Like?

Hearing these two words suddenly made him want to laugh. When the apocalypse comes, who is qualified to hope for love?!

In this way, the two of them arrived on the second floor, entered a classroom at random, and prepared to leave.

Li Yihui glanced out the window and teased: "There are three zombies down there. Do you want me to help you lure them away?"

"Need not!"

Zhang Fan responded casually and was about to climb out of the window, but the next second, he looked at a zombie on the ground not far away, feeling a little dazed.

It was a zombie that looked very similar to an ordinary zombie. The only difference was that the zombie's head seemed slightly larger, and its cheeks were bulging as if it were blowing up balloons.

"This gesture..."

Zhang Fan suddenly thought of something, his pupils shrank instantly, and he shouted: "Get down quickly!"

Without saying a word, he crawled to the ground and crawled quickly to the side, as if he was trying to avoid something.

Although Li Yihui had some thoughts of competing with Zhang Fan, he was not stupid, and he did not have an arrogant air. The moment he heard the warning, he did not think too much and just followed him to the ground.

"Bang~!"

"Zizzizi~~!"

The next second, the glass shattered, and a pool of what seemed to be liquid rushed into the classroom and hit the ground heavily.

"Chichichi~~!"

In an instant, the cement floor began to boil violently, as if it had been heated by high temperatures.

At the same time, an unpleasant smell spread out, strongly impacting Li Yihui's nasal cavity.

"sulfuric acid?"

Li Yihui looked at the boiling liquid on the ground in shock, feeling frightened in his heart.

If Zhang Fan hadn't reminded him, he would be the one lying on the ground being boiled!

"It's corrosive venom..."

At this moment, Zhang Fan, who was already hiding far away, frowned and said: "A kind of mutated zombie, also called venom zombie..."

Venom zombies are a type of mutated zombies that can spit venom. They usually disguise themselves as ordinary people and blend in among them. The only way to tell them apart is that when they attack, their cheeks look like fishing drums.

Why are there venom zombies in the laboratory building?

What really shocked Zhang Fan was this.

In the last life, a group of them stayed in the laboratory building for more than four days, and on the fifth day, they moved to the teachers' dormitory.

Along the way, Chang Xu and others often came out, but I had never heard of them encountering venomous zombies.

Zhang Fan recalled it carefully. In his last life, when he heard about the legend of venomous zombies, it had already been a month since the end of the world, and they appeared in other schools.

This made him very surprised and didn't understand why there were venomous zombies downstairs.

Has the future changed?!

Zhang Fan is a little worried. If the future is changed...

No, that will definitely change in the future!

When he thought about it carefully, he realized that Chang Xu and others had been killed by him, so naturally the same situation as in the previous life did not happen.

Moreover, in this life, Li Yihui and the others were still shouting slogans in the classroom, attracting crawling zombies.

So, this venomous zombie was also attracted?!

Zhang Fan sat against the wall and thought, thinking that it was impossible. After all, if there were venomous zombies in the school in the previous life, it was impossible that they had not encountered them during the first month of cleanup.

"Hey, what should we do?!"

On the other side, Li Yihui followed Zhang Fan's example, leaning against the wall and asking in a low voice.

At this moment, he was not as high-spirited as when he went downstairs before, with a look of fear on his face.

Zhang Fan glanced at him and ignored him. Venomous zombies have a characteristic. The venom is limited and it takes time to replenish it. They will not fire randomly before locking the target position, so he is not worried about the venomous zombies spraying randomly.

Now, the most important problem is that the venomous zombies that shouldn't appear suddenly appear.

Suddenly, Zhang Fan thought of a possibility. Is it possible that this venomous zombie is not the one he saw a month ago in the previous life, but a new one in this life?!

Natural birth?!

Change from other types of mutations to venom mutations without the influence of other variables?

impossible!

Zhang Fan directly denied it. After he was reborn, the only thing he changed was Chang Xu and his own powers. In the school, currently, the only difference from the previous life is that they shouted slogans...

Therefore, if this venomous zombie was not attracted here, then it was a newly born one...

Through crawling zombie corpses?!

Zhang Fan frowned, feeling that the only variable now was the corpse of the crawling zombie.

If ordinary zombies eat the corpses of mutated zombies and have a chance of mutating, then everything would make sense.

Zhang Fan thought about it carefully, trying to recall whether there was a similar situation in his previous life.

Unfortunately, in his last life, he and others were mostly cleaning up ordinary zombies, or working as cannon fodder, and basically did not deal with mutated zombies.

The time when you can really hunt mutant zombies is one year after the apocalypse. At that time, you can rarely see ordinary zombies in the university town. Basically, the zombies you can encounter are mutant zombies.

Therefore, after thinking about it, Zhang Fan still didn't understand whether the corpses of mutated zombies could increase the possibility of mutation of ordinary zombies.

"Forget it, no matter what, let's kill this zombie first, and then check to see if the body of the crawling zombie is still there..."
