Detective Zhang Piao (played by Dong Piao) was killed by drug lord Deng Liyang (played by Fang Gang) while investigating a drug manufacturing case. Deng disguised the scene as Zhang Piao committing suicide due to gambling debts. After his death, Zhang Piao was unwilling to have his reputation damaged, so he bribed the judge in the underworld to return to the world, and thus began to look for a savior to avenge his hatred. On this side, the new police officer A Xing (played by Zhou Xingchi) and Zhang Piao's old partner Li Jin (played by Feng Cuifan) formed a new team. Zhang Piao was destined to savior because A Xing was his savior, so he possessed the gun and cast a spell to help A Xing approach Li Jin's daughter A Yu (played by Chen Derong) to help him take revenge. Deng Liyang had a premonition that Zhang Piao would return to the world, so he asked the evil magician who was destined to be Zhang Piao to help. Li Jin, who practiced Maoshan Taoism, was disciplined by Zhang Piao and A Xing. He was dissatisfied and waited for an opportunity to retaliate, but was used by the evil magician to seal Zhang Piao's ghost. With the guidance of the founder of Maoshan, Ah Xing and Li Jin prepared a magic medicine to break the magic, and even asked the founder to possess his body to fight against Deng Liyang and the evil wizard.
