"I want to know how you know these things, where did this potion come from, and how did Brother Shui have this potion?" I continued to ask questions.

"A few years ago, my brother and I were both lab workers. To be precise, we're miscellaneous. We were tied for the top spot in high school for a long time, and after one of the school hours, our homeroom teacher took us to meet a man in his 40s. He said that he saw our talent and wished we could assist him in his experiments part-time, which would pay well. This person is Wen Bing, the smartest person I know. Most of the knowledge I talked to you, including most of the knowledge that Brother Shui talked to you, was taught to us by the civilian soldiers. It is said that it is a laboratory, but in fact the number of experimenters is very small, and it is said that the people there are well-known people in related fields. According to Wen Bing, the lab had a companion he trusted very much, but after an argument, they parted ways. The work of Wen Bing is to study the technology of time rewinding.

After going to the laboratory, we realized that although we had learned all the textbook knowledge of physics, mathematics and other subjects in the university in advance, we could not give Wenbing any help in the face of his knowledge. In the final analysis, Wen Bing is just looking for two obedient helpers to engage in hygiene and take down reagents every day. But in getting along with Wenbing, we really saw a lot of things, and with a good part-time income, we are also willing to stay here.

Until one day, I don't know what happened between my brother and Wen Bing, and Wen Bing killed our good friend Oyster. He really loves oysters, so he took this name and was the only friend we had in high school. Later, Wen Bing was sentenced to life imprisonment, but his brother continued to do Wen Bing's experiments. I couldn't understand why this was happening, and my brother had to help Wen Bing continue the experiment. Actually, I don't have much memory of my brother doing experiments. Because after many experiments are completed, they need to be reset retrospectively through time. I know a lot of things because of an experiment manual.

This experiment manual records in detail my brother's next itinerary, what day and what experiments to do. The experiment manual should have been done very early, and the experiment goal was handwritten later. For example, after your experiment, the next experiment is the human centipede experiment, dated May 31, with a handwritten parenthesis at the end, and the names of your three roommates are in it. The time and content of the experiment are fully choreographed, and the experimenter is constantly updated. So I need to steal copies of this lab manual regularly and put it back in its place. Because I know that this manual is in my brother's school bag, and I can start as long as he is not there. The reason why I know some experimental methods is that Wen Bing communicated with us about what kind of experiments we need to do and how to operate them if the time backtracking technology is successfully completed in the future. And complete, the specific experimental methods of all experiments, there is a detailed list of experimental rules, which Wen Bing wrote before the development of the potion was completed. The experiment manual was arranged and written by my brother himself, and what he did was the experiment in the experimental rules. So the detailed rules of the experiment should be on my brother, and I haven't found it, and I can't understand why my brother would do such a hurtful thing. When Wen Bing told us about some future experiments before, he did not mention any human centipede experiments, and Huilin's tolerance experiment was already the most breakthrough in the lower limit. Ah Ping sighed.

I recalled what Brother Shui said to me: "According to him, this is an important experiment on the road to perfecting the technique of time rewinding. I don't understand the purpose of the experiment, but I can't stop him, and if he wants to, what we're doing, saying and feeling will cease to exist. ”

Ah Ping said to me: "But if you want, you can go back in time and persuade him in different ways until he is willing to stop experimenting." Even if you keep going back in time, the experiment can never begin—"

"I don't want to." I interrupted Ah Ping's words, "I can know so much now because of chance. I promised Brother Shui not to interfere with his experiments again, and he didn't go back in time to wash away my memory. If I go back in time and persuade Brother Shui, he may think that I know too much and too much trouble in other timelines, and directly end my experiment, or even change the subject of the experiment. And it makes sense to keep going back in time and keep the experiment from starting? According to what you said, after the experimenter goes back in time, pretends not to go back in time, and keeps repeating the thirty days in his life, he will eventually collapse and choose to cooperate. And I only have two days, so I'm going to break faster. And if it's really for the better development of human beings, to be honest, my desire to stop Brother Shui is not strong......"

Ah Ping sighed: "If you really think so, I won't force you." Something happened before that made me realize that respecting the experimenter's own will is the most important thing.

In fact, after many experiments are completed, they will go back in time to before the experiment happened, so I remember that my brother has done very few experiments, and even fewer memories of interfering with my brother's experiments. Without the lab manual, I would probably have been clueless about what my brother was doing.

Half a year ago, my brother texted me on his mobile phone and told me something. He completed an experiment on the tolerance of potions to patients with certain types of cancer. During the experiment, after the patient drank the potion, the cancer cells were stimulated to grow rapidly, and his condition worsened sharply, and he soon lay down in the ward.

I didn't know for some reason that I knew the situation, and I couldn't bear to let the patient suffer from illness or even death, so I went to find the patient, and wanted to inform him in advance of the method of time rewinding, so that as soon as the patient had a chance to relax, he would go back to when he had just drunk the potion and his condition was not serious. Unexpectedly, as soon as I entered the ward, before I could tell me how to go back in time, the patient grabbed me by the collar of that timeline.

The reason why my brother knew about this whole thing and what the patient said next should be because the patient took the initiative to confess to his brother and expressed his willingness to cooperate with the experiment. The patient told me at the time that he had repeated this process hundreds of times. He also came to understand a lot of things, and realized that after his death my brother would go back in time to before he drank the potion.

But he did not dare to face death, and every time he had a premonition that his life was coming to an end, he was overshadowed by that fear of the unknown. He didn't dare to face it every time, so he had to take advantage of the fact that his body still had a chance to relax and breathe in the pain, and went back to when he first drank the potion.

It was my hypocrisy and self-indulgence that harmed him. If he didn't know how to go back in time, he would have died in the first experiment, everything would have ended, and time would have gone back to before he drank the potion to aggravate his condition. But knowing the way to go back in time, he never had the courage to face death. The elder brother did not witness the results of death, but only heard that the patient said that he would definitely die in the future, and he would definitely not end the experiment early. This time he made up his mind to face death and put an end to it all.

After receiving that text message, I figured out a lot of things. Since then, I have stopped interfering with my brother's experiments. Although it is said that it is because of time back, I don't remember any experiments that my brother has done, but I know about it through the experiment manual. But this human centipede experiment really broke through my lower limit, no matter what means I used, I wanted my brother to not be able to start the experiment. Although after the end of the experiment, nothing will exist. But the cancer patient would rather repeat it hundreds of times than dare to face it, which shows that in the current world, the pain and fear of the experimenter are real. So I can't help but want to turn to you and help me stop this.

If you really want to sacrifice your roommate for the sake of so-called human development, I won't force you, because I have learned from the past, and I won't force any more experimenters. ”

"I never thought of it that way, but theoretically, I couldn't. Brother Shui's experiment has been going on for more than a year, even if I carefully prepare everything and say a perfect score essay in front of him, what is it, will he give up halfway? Once he failed, he went back to before my experiments began, and all memories of me ceased. Of course, if the experiment is successfully completed, and Brother Shui's hundreds of repeated experiments are completed, he will go back to the fact that the experiment did not start at all, that is, before my roommate was kidnapped, then the memory of my conversation with Brother Shui, and Ah Ping will also disappear. I'm sorry, I want to help stop this experiment, but I can't help it. ”

"Do you think so, I understand, and I won't force it." Ah Ping's tone was full of loss.
