In the 22nd century, the civilization mentor used "one hundred years of natural lifespan" as a monument to draw a sacred boundary for the race heading towards the star sea. Thousands of years later, humans have been able to use dark matter as a canvas to rewrite the rules of the universe, but they still guard this ancient boundary devoutly-not pursuing eternal life, but only pursuing the infinite glory of civilization within a limited time. During an experiment to manipulate the fundamental laws of the universe, weak ripples of time and space swept into the past, sweeping away the consciousness of Meng Xinghai, an ordinary "cow horse" in the 21st century. When he woke up from the medical cabin of the future, he became the only alien in this almost god-level civilization who feared death, longed for immortality, and understood "involution" and "anxiety." He is not a hero, not a savior. He is a living artifact, a systemic anomaly that needs to be disposed of properly. There were only two choices before him: to forever explain his backwardness as a specimen of the "Pre-Mentor Era" in the museum of the Earth Temple; or to wash away all memories of the future and return to the short and anxious past that he desperately wanted to escape. It's a parable about how "advanced" and "backward" define each other. It is also a story about why a civilization chooses not to do something that is greater than what it can do.
