Seventeen years into the spiritual qi revival, Gu Changsheng, a temporary clerk in the Archives Department, spends his days filing records, slacking off, and getting scolded by his captain, Su Wanqing. Then he discovers that the photos attached to two supposedly closed murder cases show the same face: the dead are coming back to life, and the case files are lying. His golden finger, “Myriad Things Archive,” can read any lingering memory, but each use costs him an important memory from his past. While carrying his gravely injured captain as they flee, he grumbles, “Why the hell does a temp like me have to do this kind of thing?” From the archives to the seal at the bottom of the abyss, from a wisecracking slacker to the one who breaks the deadlock of an era, he finally stands before Zhao Wujiu. The man smiles and tells him, “The better your memory, the faster you forget. Do you know what the memory you lost was?” He touches the token in his pocket, engraved with the words “Gatekeeper,” and remembers the words he wrote himself: “Stop investigating. If you keep going, you'll forget me.”
