Fishmonger Gao Qiqiang was reborn on New Year's Eve in 2000. He gave up the underworld and started working as a police co-operator, using his memories of his past life to repeatedly solve major crimes. He and policeman An Xin changed from rivals to comrades-in-arms, and they fought step by step in the game of good and evil in Beijing and the sea. In the end, they came to power, and together with An Xin, they guarded the peace of Beijing and sea, and embarked on a career path that was completely different from the previous life.
It's very beautifully written, I like it
