During the tyranny of Sui Yang, the Grand Canal stretched thousands of miles and bones were exposed in the wild. {Yu Wenyue}, a descendant of the Northern Zhou royal family, became a tracker. Seeing the officials wreaking havoc and the people being displaced, anti-Sui fire was ignited in her heart. In order to save the weak girl, he accidentally killed an official and was forced to flee to the end of the world and join the Wagang Army. Relying on his extraordinary resourcefulness, Yu Wenyue repeatedly came up with ingenious strategies, but was jealous and excluded by Li Mi. Frustrated, he turned to Li Yuan and his son, helping them lead the army to break through Chang'an and defeat Dou Jiande, making great contributions to the unification of the Tang Dynasty. After becoming famous, he refused to enjoy the generous salary of a high-ranking official and returned to Sui Di. He used his own efforts to appease the people and rebuild their homes, and eventually became the "Sui Di righteous man" praised by both sides of the canal.
