Let's walk together for the rest of our lives. If the host says to leave, she will leave.

Dr. Zheng didn't care about Cheng Mu's little mood. He peeled the apple with a fruit knife, and his tone sounded like a friend chatting at home.

"You agreed to sit down and talk with me in order to avoid pain, so why didn't you kill those people just now?"

Shortly after Gu Ling left, Dr. Zheng used the ashes that Cheng Mu inhaled into his body to control Cheng Mu and gave him orders remotely.

Disobeying his orders would result in heart-wrenching pain, but in the end Cheng Mu just used his supernatural powers to injure those people.

It just so happened that he was also very interested in the abnormality of Cheng Mu, so he simply asked Cheng Mu to come to him.

However, what surprised Dr. Zheng was that he originally thought that based on Cheng Mu's performance, he did not expect that Cheng Mu obeyed him as soon as he gave the order.

What an interesting person.

Cheng Mu said coldly: "I don't want to kill."

[What kind of pervert is this idiot? Why would he kill people for no reason? ]

Dr. Zheng placed the intact apple peels neatly on the plate: "Let me guess, it's for friendship? Family? In short, it's for feelings, right?"

"nonsense."

Dr. Zheng stared into Cheng Mu's eyes: "What about Chen Ming? Is it also because of feelings?"

As a mad scientist with high intelligence and strong abilities, Dr. Zheng’s favorite thing to do in the apocalypse is to observe.

Observation can help him discover some interesting people or things, and make him feel that the world is not so boring that it is hopeless.

Cheng Mu was a little confused. Who is Chen Ming?

It took him a while to remember this person. Of course, there was no relationship between him and Chen Ming. If you really want to talk about it, they were enemies.

As for why he didn't kill Chen Ming, it was simply because as a law-abiding citizen, he could not and was unwilling to kill anyone.

Cheng Mu sneered: "I've already said it, I don't want to kill anyone."

Cheng Mu's expression looked like he deserved a beating, and his tone of voice was arrogant and irritating, but his eyes were clean and bright, as if they could not tolerate the slightest bit of filth.

As the world has come to an end, who doesn’t have blood on their hands?

Even ordinary people who have no ability to resist will become numb or alert and uneasy because they are used to the intrigues and deceptions in the end times.

In short, no one is like Cheng Mu, who is so clean and thorough that he doesn’t seem to be a person from the end of the world.

This world is boring, dirty, selfish, cold, and rotten like a lump of mud. Why should Cheng Mu be clean?

Dr. Zheng's eyes turned cold. He put the apple on the plate, wiped his hands with a handkerchief, wiped the fruit knife clean, and placed it casually on the table in front of Cheng Mu.

He took out a transparent glass tube from his white coat pocket, which was one-third full of light blue liquid.

"Do you know why those people lost their minds?" he said as he opened the glass tube. "Because I injected a drug into the zombies that caused them to have hallucinations, and then under tremendous mental pressure..."

"Bang!" He opened his hands and narrowed his eyes. "It exploded like fireworks."

Cheng Mu stood up suddenly, and the sharp whistle rang again. This time the pain was worse than before, and he growled in pain like a wounded beast.

Dr. Zheng took the whistle away from his mouth. The whistle was hung around his neck by a thin rope. When his fingers loosened, the whistle swayed slightly in front of his chest.

"Those people are different from you. Their collapse is a matter of time. I don't even need to pay attention to them. But you are the one I chose, so I need to control you personally."

Dr. Zheng lifted up his sleeves and untied the blood-stained white gauze on his wrist. The scar on his wrist was shocking, and the flesh was turned outward and blood was still oozing out.

He opened the glass tube, picked up the fruit knife on the table and slashed the wound. The blood merged with the light blue liquid and turned into a dreamy pink.

He seemed to be explaining his research results to his students: "As long as my blood is mixed into it and the drug enters the human body, a certain connection can be established between us. The longer I live, the faster they die."

Dr. Zheng turned the bloody fruit knife around and handed the handle to Cheng Mu: "Cheng Mu, do you want to save them? For your great...feelings."

Cheng Mu slowly raised his head, his eyes passed over the dagger and whistle, and finally fell on Dr. Zheng's smiling face.

Whether it was for saving others, for saving himself, or for so-called justice, he had no reason to refuse this proposal.

The pain from before still lingered in his body, and Cheng Mu's hand was trembling slightly when he raised it.

But he took the dagger accurately.

The smile on Dr. Zheng's face widened. You see, principles are nothing but clouds. As long as desire is involved, no one will refuse an option that is beneficial to them.

Cheng Mu gripped the dagger tightly, grabbed the whistle hanging on Dr. Zheng's chest with one hand, and the sharp dagger cut the thin rope.

Cheng Mu's lightning power, which had been ready for a long time, hit Dr. Zheng, and he quickly distanced himself from Dr. Zheng.

He stood aside, looking at Dr. Zheng who had temporarily lost his ability to move, and crushed the whistle with one hand.

The whistle broke into pieces and fell from his palm. Cheng Mu clapped his hands and grinned.

"Want to die? I don't agree. Hey! You are such an interesting person. You don't want to live anymore but you want to drag others down with you. Tsk, what a pervert."

[Isn't it just some broken potion? Dr. Bai will definitely be able to research an antidote. Besides, there is Gu Ling, she will definitely have a solution.]

Gu Ling was able to bring him back to the real world, and he had also found a way to control the direction of the novel world. He firmly believed that Dr. Zheng would not be able to cause any waves.

Moreover, not killing is Cheng Mu's bottom line. He doesn't want to have nightmares every night after returning to the real world and spend the rest of his life carrying the burden of his past of murder.

He has a reverence for life and always believes that he has no right to deprive others of their lives.

He follows the rules of the world, and his world is not this apocalypse.

Dr. Zheng looked at Cheng Mu's firm and pure eyes, and his heart, which had been calm for a long time, began to surge with turbulent waves.

A demon in his heart screamed: Destroy him! Destroy these eyes!

"Cheng Mu, kill me."

This sentence is not in Chinese, but an ancient mysterious language. Cheng Mu cannot understand it, but he does not need to understand it.

Because he suddenly lost his self-awareness.

Cheng Mu's incessant chatter suddenly stopped. Gu Ling thought something was wrong. When she rushed into the room, she saw Cheng Mu stabbing Dr. Zheng with a dagger in his hand.

"Cheng Mu!"

Gu Ling shouted, and Cheng Mu's movements paused for a moment, and this pause was enough for Gu Ling to rush forward to stop him.

Gu Ling grabbed Cheng Mu's wrist hard, and the dagger fell to the ground with a clang. She kicked Dr. Zheng and kicked him away.

Only then did she have the mind to observe Cheng Mu's condition. Cheng Mu's eyes were blank, like a soulless puppet.

Gu Ling's heart skipped a beat.
