This drama is adapted from the classic novel "The Romance of Sui and Tang Dynasties". Qin Qiong (played by Yan Kuan), a descendant of a famous general of the Northern Qi Dynasty, grew up with Cheng Yaojin (played by Jiang Wu) since childhood. With his martial arts, he was promoted to a junior official by the government. One day, Qin Qiong encountered Li Yuan being intercepted by Prince Yang Guang (played by Fu Dalong), and single-handedly rescued Li Yuan's family. When he came to Luzhou, he had to sell horses to make a living. Fortunately, the proprietress was very righteous and secretly helped him. Cheng Yaojin robbed Yang Lin of 160,000 taels of silver in Changyelin. On the birthday of Qin's mother, Cheng Yaojin was arrested. In order to rescue Cheng Yaojin, the brothers who swore by Jialiudian planned a rebellion and prison robbery. By chance, Cheng Yaojin became the devil of Wagangzhai. Emperor Yang of Sui (played by Fu Dalong) went to Yangzhou to see Qionghua. Wagangzhai joined other rebel forces to gather in Siming Mountain with the intention of killing Emperor Yang of Sui and overthrowing the Sui Dynasty. Li Shimin (played by Du Chun) took the opportunity to run back to Taiyuan and started a rebellion. Li Mi fled to Wagang and was supported by everyone. Li Shimin was captured by Cheng Yaojin when he visited Wagang at night. Li Mi wanted to kill Li Shimin, but was dissuaded by Qin Qiong, who took the opportunity to release Li Shimin. With the help of Qin Qiong and others, Li Shimin eliminated dissidents in a battle at Xuanwu Gate and became Emperor Taizong of Tang, creating the Zhenguan Reign.
