Shen Zhiyi was framed and imprisoned by her stepsister Shen Rourou. She thought her life was ruined, but she awakened in the darkness with devouring powers - she ate the memories of gang leaders, swallowed their methods, and climbed to the top of the abyss step by step. Lin Ya, the doctor in prison, guided her step by step, and Lao Scar secretly taught her the Dharma. However, Jiang Jin, the only one she trusted, carried a secret that could destroy the entire underground empire. When her power went out of control, and when the truth about her mother's death was revealed, she finally understood: it was not the enemy that was being swallowed, but the light she once believed in.
