I'm Here to Dismantle the Hell of Reincarnation.

Lu Yan, a senior high school student, fell asleep during his last mock exam and dreamed of a bloody ending. Sea of ​​blood and bones, the earth turned into a prison, he betrayed the Palace of Samsara with the authority of the "Four Seals" and tried to break the cage, but was obliterated by the faceless Lord with one finger. Before he died, he used his remaining authority to activate the forbidden program and stuffed his will into the gap in the hell's reincarnation system. When he opened his eyes again, he returned to the senior high school classroom. An almost transparent fragment of the reincarnation seal on the back of his hand told him that it was not a dream. A cold reminder in the corner of the field of vision - [Round 1: City Level Reincarnation Trial·Blood Mist Arrival] [Countdown: 24:00:00] - announces that a "new entrance" destined to bloodbath the entire city is about to begin. As the blood mist covered the sky and the sun set, bus accidents, screams on the streets, and broadcasts in the city's consciousness made ordinary people face reincarnation for the first time: most people were forcibly carved with the [Reincarnation Seal·First Seal] and became new samples for selection. However, Lu Yan was marked as [Retrospective·Zero Seal]. He was in the gap between the rules and was allowed to watch for a short time. He was also targeted as an "unstable factor." In this life, he is no longer satisfied with being the strongest person in reincarnation, but wants to survive and upgrade while prying open the gaps in reincarnation in the trials of the heavens. Reincarnation is not salvation, but a prison. Since we are forced to do it again, let's start from this time and break the reincarnation bit by bit.
