Wu Di (played by Xiao Shenyang) makes a living by repairing shoes. His greatest pleasure is to read the martial arts comic book "Flying Sword". One day, he met a shoe repair woman Yuelu (played by Lin Xilei), who is the cousin of the emperor (played by Chen Zhipeng). Because she didn't want to be the queen, she ran away. The emperor sent Yang Guo (played by Zeng Zhiwei), a master of the inner court, to kill her. Wu Di accidentally killed the rapist Tian Baguang and saved Yuelu. In order to return the shoes to Yuelu, Wu Di went to Mount Tai. On the way, Wu Di encountered the river thief Duguhong (played by Zhao Benshan) and his disciple (played by Cheng Ye). With the secret help of the hermit, he repelled Duguhong. The old man lost his deep inner strength to him before leaving, and gave him a copy of "Nine Yin Manual". Because he only looked at the picture, he threw it aside. Tian Baguang's fellow Shennong sisters Pink Phoenix and Red Phoenix came to settle accounts with him, but he was unscathed while the other side suffered heavy losses. While escaping from the pursuit, he fell into a bottomless abyss, but met an enemy who was a master from the outside world (played by Wu Zongxian), but fortunately he escaped without any danger. However, in the end, Wu Di still lived in the black shop opened by the leader of Shennong (played by Tien Niu), and met his sweetheart Yuelu...
