Former security captain Su Can was framed and set on fire by He Xing for five years and imprisoned. In prison, he learned from the hidden master Chen Lao, who taught him peerless medical skills, martial arts and ancient Xuanhuang scriptures. He became the Dragon Lord and was entrusted to protect Ye Zimeng, the daughter of the Ye family, after he was released from prison. At the same time, he had two major obsessions: to investigate the unjust case and to protect his four-year-old daughter Su Xiaoxiao. After being released from prison, he goes all the way to liquidate his enemies, make good friends, clear obstacles in business and martial arts, and finally wash away his grievances, build a complete family, and help his lover reach the top of his career.
