Seventeen years after his spiritual energy was revived, Gu Changsheng, a temporary worker in the archives department, spent his daily life filing files, fishing, and being scolded by team leader Su Wanqing. Until he discovered that the photos of two closed murder cases were of the same face - the dead person pretended to be the corpse, and the file deceived the person. The golden finger "Everything Archive" can read all remaining memories, at the cost of forgetting an important part of the past every time it is used. While running away with the seriously injured captain on his back, he complained, "Why the hell would I, a temporary worker, do such a thing?" From the archive room to the abyssal seal, from the talkative gangster to the era breaker, when he finally stood in front of Zhao Wujiu, the other party told him with a smile: "The better your memory, the faster you forget - do you know what the memory you forgot is?" He touched the token with "Gatekeeper" engraved in his pocket and remembered the words he had written: "Stop checking, you will forget me if you keep looking."
