The next day, the two men discuss the future of the Immortality Project. The former wants to continue the project, but the latter wants to finish it. He tells the latter that he has already told the management that he will return to finish the project they want. He also tells the former that hua Ruan will not speak about the incident that night. The two men decide to take a nap first. The latter tells him that he is so smart that he would not tell him even if he had asked him. He says that the relationship between them is "one step closer" and that the longer he lives, the more he sees. He explains that the project will not only make people immortal but also delay aging. The defect in the project is that it needs to be replaced with new, vigorous organs after a certain period of time. This is the major task, he says. The people who depend on rebirth for huge benefits will be the ones who will face rebirth the most. The second part of the conversation is about how he killed one of the patients and told the doctor that if he did not come back, he would kill more patients. The doctor agreed to the plan because he felt that some trivial people were behind it. When the doctor left, he always felt that the doctor was planning something secretly. He tried to monitor the doctor but the people he sent there disappeared. The "immortality" project was stagnant because of the doctor's departure, so he decides to talk about it when the doctor comes back.
