A sudden change occurs in the Jinling Palace and the princess is murdered. Mr. Yang recruits the young hero Yue Xiu to solve the murder. Yue Xiu received the true biography of the strange hero, and became invincible in the world with his fists, palms and weapons. Yue Shaoxia came to Yang Mansion and met Miss Yang Yuyan by chance. Not only is she outstanding in appearance and charming, but she also has a solid foundation in martial arts. Yue Xiu and Yu Yan sneaked into the palace and found out that the death of the princess was caused by the underworld organization "Dragon and Phoenix Society". Members of the association infiltrated everywhere, from the royal palace to the state capital, creating civil strife and harming the government. In order to get rid of the traitor, Yue Xiu, Yu Yan, Tan Yun, Ma Peng and other heroes escorted the Seventh Prince into the capital. The emperor granted Yuexiu the title of Marquis of Buyi, gave him the golden phoenix scissors, and gave him the power to kill first and then report. Yue Xiu, Yu Yan and other powerful people were ordered to clear the emperor's side and eliminate the Dragon and Phoenix disciples. The heroes fought to kill the leader of the Dragon and Phoenix Guild and put an end to a bloody catastrophe.
