Sin Game, Nth Player

There is an urban legend circulating in Haijin City: If you receive a black invitation letter late at night, congratulations, you have been given a chance to be reborn; if you refuse, then when the sun rises tomorrow, you will become an artistically processed corpse. This is an underground game called "Abyss Echo", which selects highly intelligent criminals for killing, and also selects desperate people for gaming. Qin Che, a former criminal psychology genius consultant, was ruined due to a miscarriage of justice three years ago, and his sister disappeared mysteriously. In order to find the truth, he took the initiative to touch the black invitation. Since then, Haijin City has had a "fraudster" who walks in both black and white. In the eyes of the police, he is an unfathomable crime-solving machine, while in the eyes of criminals, he is the god of death who harvests lives. "Welcome to my game, now, please place your bets."
