Because humans continue to pursue higher, faster, stronger and longer life, the earth was eventually overwhelmed, completely collapsed, and no longer suitable for human survival. As a last resort, humans began to migrate. Shengsheng, who was more than 300 years old, drove an interstellar spacecraft to explore new planets in the vast universe. After experiencing several failures, he accidentally fell into a black hole and went back in time to when he was in elementary school. His parents were still young at that time, and he still had some memories. He tried hard to slow down the development of human beings, and not to pursue the transformation of nature too much, but to let nature take its course, so as not to suffer the ultimate backlash from nature. In the end, he enjoyed this slow and natural life.
