Delivery boy Lin Xiaoyou accidentally obtained Jiang Ziya's bronze fishing rod and was forced to be involved in a cause-and-effect war that spanned five thousand years. The 108 causal rhythm devices scattered around the world - the scalpel of the murderer Bai Qi, Yang Guifei's smart dress, Tesla's quantum coil - are dragging modern civilization to the edge of collapse. Every time he fishes for historical memories to recover the rhythm instrument, the Karmic Fire Tattoo erodes an inch of flesh and blood, and the thief Han Jiuzhong, who is dormant in the dark, is using the stolen Jade Seal of the First Emperor to rewrite the rules of the world. When the neon city and the ancient battlefield overlap in the data flow, the fishing line at the end of the fishing rod has entangled the last future of mankind.
