[Mystery] [No Female Lead] [Rules] The blood moon hangs overhead, and the rules descend. A senior-year classroom becomes a sealed death trap, where thirty-eight students are forced to take part in a test that costs them their lives. Any violation of seemingly ordinary school rules, eating snacks, combing your hair, fooling around, triggers a fatal curse. Once half the students have died unnatural deaths, the survivors must complete a series of terrifying tasks in a school transformed into a maze of flesh and blood.
Reborn Wang Ruicheng carries memories of his past life and tries to find a way out of their desperate predicament. But he discovers that the truth behind the blood moon is even more cruel: the school is an experimental ground for higher-dimensional beings, and only flawless virtue and collective sacrifice can break the deadlock. Faced with rules that paradoxically demand murder, the mutations and betrayals of his classmates, and memories of his past life gradually resurfacing, Wang Ruicheng leads the last survivors on a mission to shut down the source of the blood moon.
But the ultimate way to break the deadlock requires someone to remain forever at the heart of the nightmare. When dawn finally comes, only eight teenagers remain in the empty classroom, having lost all memories of what happened, along with their homeroom teacher, sitting alone in a corner with tears in her eyes, not knowing why she is crying. The rules have fallen silent for now, but the shadow of the blood moon has never truly faded...
