Which protagonists in novels undergo human experiments to obtain eternal life?

In different works, the " Eternal Life System at the beginning " had different ways of presentation and subsequent developments. In some novel plots, such as the main character in the Immortality System, he might be faced with the predicament of surviving in a famine year. He had to work hard to obtain resources to maintain his life while using the Immortality System to improve his abilities, such as cultivating techniques and increasing his realm. At the same time, he had to deal with the covetous and threats from the people around him. In science fiction, the eternal life system was related to the uploading of consciousness. If he obtained such a system at the beginning, it meant that he might have to face a major change in the structure of human society and ethics. From a social perspective, if the eternal life system operated according to business logic, the immortal might need to work in the eternal life system to earn money in exchange for service experience, such as being an NPC in the meta-universe game, an actor in the theater, or a service staff in the conference. From an ethical point of view, there might be criminals in the eternal life system, and the police would be needed to maintain order. The education industry would also exist, and the " people " in the eternal life system were the continuation of human consciousness in the real world. It might also involve the restoration of historical figures and other situations. In fantasy works, such as the plot of the " Eternal Life " animation, the protagonist obtaining the eternal life system might be related to improving his magical power, fighting for treasures, fulfilling the agreement, and other related plots. For example, Fang Han wanted to obtain the first place on the Mountain and River Rankings in order to obtain the Yin-Yang Longevity Pill and break through to the Divine Power Realm in order to fulfill the ten-year agreement.

In Minecraft, players could obtain the quest by opening the quest list, finding the Eternal Island quest, and accepting it.
