In 1990, when Huaguo's 749 Bureau sealed away its top-secret files, no one imagined that the young man organizing old records in the archive room would rewrite history. Cheng Yi made an unexpected discovery: encrypted files containing the 749 Bureau's darkest forbidden experiments.
Over the next twenty years, from the uprising of living dead in the Forbidden City's underground palace, to alien bones in the sandstorms of Lop Nur, and finally the "Kunlun Project," which triggers a global catastrophe in 2025, Cheng Yi discovers at supernatural incident sites that every artifact he restores is warning him of the countdown to doomsday.
