"The modern city suddenly entered the "Era of the Advent of the Gods", the rules were broken, and restricted areas, strange areas, and mental hospitals appeared around the world.
- The protagonist, Lin Shisan, was forcibly sent to the world's most terrifying "Thirteenth Mental Hospital" due to schizophrenia inherited in his family - the people detained here are not ordinary patients, but demigods/lunatics/containers of rules chosen by the gods.
- Awakening on the first day of admission [Death rollback system]: Each death is forced to roll back to 0:00 on the day of admission, and the sanity value (San value) is permanently -1 (initial 100). The more the number of deaths, the stronger the "madness attribute", which can be transformed into terrifying abilities such as insight into rules, shock with crazy words, sudden increase in combat power, and proving the truth through madness.
- The core declaration of the system (a golden sentence will appear every time after rewinding): "The crazier you live, the more stable the God of Death will be. "
- The hospital is a multi-layered rule domain. Each layer corresponds to a kind of divine will/rule fantasy. Violation of the rules will result in death or mutation. "
The main theme of the work: "Urban high martial arts + weird rules + infinite flow of death reversion + Cthulhu crazy batch + system + group portrait + passionate counter-kill + famous scene creation machine"
