Civilized Sampler

Lin Yu, a sampler at the Frequency Keeping Department, lost his sister in a cross-frequency accident three years ago. Her consciousness did not die, but was broken into four pieces and scattered among four mature civilizations that had come to an end. Ji Yuan uses algorithms to make choices for people, and everyone is happy, but no one remembers who they are; in Qingxu, everyone cultivates their hearts like immortals, and the individual is perfect, but the whole disappears in silence; Huanxu indulges in eternal dreams, and Heyuan gently arranges everything for you. The four civilizations all want to "acquire" the young Earth on the same frequency - without sending fleets or bloodshed, they just make you agree from the bottom of your heart: being taken care of is more comfortable than freedom. What Lin Yu has to do is to walk into them one by one, retrieve four keys that can only be condensed through "real understanding", and find a fifth way for the earth that does not collapse at any pole. The price is that every time he crosses the frequency spectrum, he forgets a little bit about himself, and can only rely on a notebook filled with "In case I forget" to pin down "Who am I" one by one. He thought he was the first person to set foot on this road. Until he dug into the depths of his notebook and found a page of an older reply written by himself—— It turned out that this was not the first time he set out. And this time, he wanted to see where a person who remembered how many times he had failed could go.
