At dusk when the blood moon falls, the entire campus turns into a Shura field where flesh, flesh and code are intertwined. Lin Qiu, a junior student in the Department of Computer Science, picked up a mysterious fragment of a page in the ancient books section of the library, but it turned out to be the only bug in the doomsday game that could rewrite the system rules. When his roommate Zhang Mingyu appeared with a head with compound eyes flipped 180 degrees, and when the borrowing record of "Klein's Manuscripts" pointed to the restricted area of the laboratory building, he discovered that the foreshadowing of this global digital disaster had been laid twenty years ago.
Holding the broken pages of ancient books that can tamper with the bottom of the world in his left hand, and holding the blood moon with a fatal countdown in his right hand, Lin Qiu tore his way to survival amidst the twisted rules. Use philosophical classics to build fortifications, use economics books to refine spiritual poison, and let lies become a sharp blade that cuts through space. But those "data anomalies" with purple question marks floating above their heads, those administrator protocols that grew out of system vulnerabilities, and Klein's eyes staring at all living beings from the depths of the blood moon all reminded him that the real virus is human beings themselves.
When the system designer's resignation letter was spelled out from the broken pages of the ancient book, and when the mechanical worm that should have been destroyed in 1999 crawled out of the restricted area of the laboratory building, Lin Qiu finally saw the truth behind the bloody sky: the so-called doomsday is just a recycling program after the formatting of higher civilizations failed. What he has to do now is to write himself into the source code of this world and become the "404 error" outside all the rules.
