The color on the middle-aged man's face finally changed. He quickly raised his arm, and somehow a pistol appeared in his hand.

"Don't shoot!"

Li Chenzhou swayed, reached out, and pressed down the middle-aged man's arm. He looked at the five people entangled together, including Zhang Jinlong, and said:

"If you want to survive in this zombie-infested apocalypse, you must understand zombies. And now is your best opportunity. Do you want to save these bastards who use any means necessary, even murder, to survive? Or do you want to use them to learn more about zombies and secure a greater chance of survival for yourselves and the civilians you're trying to save? The choice is yours."

With that, Li Chenzhou retracted his hand from the middle-aged man's arm. The middle-aged man stared at Zhang Jinlong, who had already turned into a zombie and was desperately tearing and biting at a person. His cheeks twitched constantly. Finally, he raised his arms again, but the hands holding the pistol slowly lowered.

Seeing him lower the gun, the other team members exchanged glances and also put down their guns. The two members with rifles ran near Zhang Jinlong and the others to prevent them from rushing towards the others.

As for the civilians in the hotel lobby, they had all hidden themselves. Even the handcuffed zombies were terrifying to them, and the further away, the better.

"There are three reasons that can cause humans to mutate into zombies. The first, and also the source of zombies, is the Hell Silk. People who are invaded by the Hell Silk and do not have antibodies will be infected and become zombies! They are also the first batch of zombies in this world!"

Seeing the middle-aged man lower his gun, Li Chenzhou turned to look at Huang Mao, Scarface, and the others who were struggling and calling for help beside Zhang Jinlong, and said.

"Hell Silk?"

The young man who liked to ask questions spoke again.

"It's those scarlet threads that descended from the sky last night and enter the human body. You, him, me, everyone has Hell Silk in their bodies!"

Li Chenzhou pointed at the young man, then at the middle-aged man, and finally at his own nose as he explained.

"So that thing is called Hell Silk?"

The young man was stunned, then asked again:

"How do you know the name of that thing?"

"Of course I know, because I just named it yesterday!"

Li Chenzhou replied casually, and the young man was immediately dumbfounded.

"The second type is like what is said in movies or novels: being bitten or scratched by a zombie. Once the zombie virus enters the bloodstream, the injured person is beyond saving. Their bodily functions will slowly be destroyed by the zombie virus. When their vitality is completely exhausted, they will become zombies."

Ignoring the young man, Li Chenzhou continued.

At this time, the first person bitten by Zhang Jinlong had already lost his breath. Scarface, Huang Mao, and another survivor were working together to hold Zhang Jinlong down while desperately calling for help from the people around them.

"As for the third type, it's like him just now!"

Li Chenzhou pointed at Zhang Jinlong:

"Not just him, but us too. Because of the Hell Silk, we all have the mutant virus in our bodies. However, because we have antibodies, it has been suppressed.

But once we die, this suppression will also disappear. So, when I killed him just now, he turned into a zombie. This rate of mutation is the fastest!"

"How did you discover... that people who are killed also turn into zombies?"

The middle-aged man stared at Li Chenzhou and asked, while also gesturing behind his back. The team members on the second floor immediately aimed their guns at Li Chenzhou.

"He told me!"

Pointing at Zhang Jinlong, Li Chenzhou said:

"This guy is called Zhang Jinlong. He was trapped in a residential area. My companion and I passed by there, and an older woman in the area called out to us for help. My companion wanted to save them, so..."

Li Chenzhou quickly recounted everything that had happened before, of course, including how Zhang Jinlong had cut his companion to use them as bait to attract zombies so that he could escape:

"After one person was cut, he covered his neck and struggled to get into a car. I clearly saw that he hadn't been touched by the zombies, but later, he still turned into a zombie!"

"Is it possible... that his knife had cut a zombie before and was also contaminated with the zombie virus, which led to that person's mutation?"

After listening to Li Chenzhou's words, the middle-aged man's expression clearly softened a lot. He pondered and asked because he had just seen that Li Chenzhou's dagger was also stained with a lot of thick, black blood, obviously from a zombie.

"He was holding a kitchen knife at the time, and... I can guarantee that he only used that knife to cut people like him, and never touched a zombie. In his opinion, humans are clearly easier to deal with than zombies!"

Li Chenzhou shook his head:

"So I had to kill him. Before, he threw firecrackers at me, causing me to be surrounded by zombies. I knew that wasn't aimed at me, just like he said, I just happened to be there.

He just wanted to get away at the time, and no matter who was standing there, he would have thrown the firecrackers at them. If we never crossed paths again, then naturally there would be no problem.

But he saw me again just now. A person like him would definitely worry about my revenge, so he would try to kill me in every possible way. I couldn't leave myself with hidden dangers, so he had to die!"

"Mm!"

The middle-aged man nodded and then looked over there.

At this time, the first person bitten to death by Zhang Jinlong had already turned into a zombie, and Scarface and Huang Mao had also been bitten and were desperately struggling and howling.

The other person was lucky. He hadn't been bitten yet. He shouted at them with a look of horror:

"I'm not with them! Big brother, you saved me when you saved them, I was there too! I didn't throw the firecrackers! Save me again, please! I don't want to die!"

Then, he looked at the middle-aged man and hissed:

"You are police officers! Are you just going to stand by and watch a civilian get bitten to death by monsters in front of you? What about your oaths?"

Hearing this person's words, the young man seemed a little moved and raised his gun to look at the middle-aged man.

"He ran out with Zhang Jinlong, and under Zhang Jinlong's instigation, he also cut someone who had been protecting him. That person was quite a bit older than him, either his father or his uncle! Are you sure you want to save someone like that?"

Li Chenzhou looked at the young man and asked.

The young man was stunned, then looked at the person again.

Seeing this, Li Chenzhou strode forward, drew his dagger, and blew the heads off all four people—Zhang Jinlong and the others—who had either turned into zombies or were on the verge of death, leaving only the person begging for mercy.

"Thank you! Thank you, big brother! You've saved me twice! I will definitely repay you, and I will never be ungrateful like that damned Zhang Jinlong. Otherwise, I will die a horrible death and definitely turn into a zombie!"

The man thought Li Chenzhou had changed his mind, so he thanked him repeatedly and swore an oath.

"The world has changed. Don't make oaths so easily. Look, your oath has already been fulfilled!"

Li Chenzhou looked at the man expressionlessly and pointed at his right arm…
