In 1975, he is sent to the countryside as an educated youth, where supplies are scarce. Bandits kidnap him and the other youths because of something buried underground, forcing them to navigate the mechanisms inside a tomb. There, he unexpectedly gains a golden finger.

He eventually becomes a sound-based antique appraiser in the cultural relics world, and can turn even a deadly tomb into his own backyard.
