On a rainy night, Yanxin rescued Jing Yuanyi, the leader of the Qinglong Gang, and learned that his biological father wanted to sell him to the old man to pay off his gambling debts, and that his fiancé Lu Ziang had clung to the powerful and broke the contract. Yan Xin decisively asked Jing Yuanyi for help, publicly humiliated Lu Ziang and tore up the marriage contract, and then followed Jing Yuanyi into the Qinglong Gang. In three years, Yan Xin transformed into the core of the gang, but she poisoned Jing Yuanyi to death on her wedding day, fulfilling the other party's teaching of "don't trust anyone". The sea of fire spread, and Yan Xin walked out of the auditorium covered in blood, but was surrounded by troops led by Lu Ziang, who had become the director, and the two fell into a confrontation again.
