The undercover captain Lu Qingyu, who was blamed for killing his father, transformed into "Zhao Yu" and lurked beside Shen Yixiao, the underground emperor of S city. However, in the process of protecting his son, the seemingly innocent but cruel killer "Lily" Shen Ci, he fell into the abyss of emotion and justice. Are the two Sanskrit blood-locking jade rings locked in lies, or the sincerity that has already deteriorated? The two-city confrontation between City S and City A looks like a prosperous city on the surface, but in reality the underground order is controlled by the "Fushenglou". The boundaries between the police and gangs are blurred. Everyone is acting. Only the blood and the Sanskrit on the ring are real. Everyone is evil / everyone is white and black, and there are no absolute innocents.
