Sun Yichen, an ordinary high school student, suddenly gained the ability to "rewind time" one day - he could go back to any point in time 24 hours ago after death. But what made him collapse was that every time he woke up after death, he would find that something was wrong with the world: his deskmate who was supposed to be in class suddenly turned into Gojo Satoru from the anime "Jujutsu Kaisen", and the class teacher turned into Light Yagami from "Death Note". What's even more terrifying is that a group of aliens calling themselves the "Space-Time Administration" have descended on the earth. They tamper with reality arbitrarily, integrating the world of animation, games, and novels with the real world, and euphemistically call it the "Civilization Observation Project." Sun Yichen was forced to struggle to survive through death and retrieval, but found that every time he was resurrected, he would enter a new fusion world-spell specialist, agent of death, demon slayer, and even the Marvel universe. He must find the flaws in each world and disrupt the alien conspiracy within 24 hours. At the same time, he must beware of a mysterious fast traveler-the mastermind behind the scenes. Until a certain resurrection, Sun Yichen found that he was no longer back 24 hours ago, but a month ago... His life had never been so long.
