Traveling back in time to become Xuan Yiwei, Song Xuan and his sister Song Qian traveled around the world relying on the "Pure Yang Wuji Boy Kung Fu". He passed the bandit-suppression test easily, solved a series of flower-picking cases, and eliminated the den of the prefect and his son. On the way home, he met a thief and learned Qinggong. When he returned home, he was forced to go on a blind date with Lin Daiyu.

From secret fights in officialdom to turmoil in the world of martial arts, he used his fists and brains to protect the people around him, and step by step uncovered the conspiracy of this mixed martial arts world.
