Yang Youan is reborn as Emperor Yang Guang's illegitimate son. In the chaotic end of the Sui Dynasty, imperial clans clash, heroes compete, and cultivators assist the tyrant, causing widespread suffering. Due to his father's dragon energy suppression, Yang Youan cannot cultivate and is confined to Jiangdu City. Just as he despairs, a ethereal voice rings out from his soul: 'Water the flowers with canal water every evening to obtain treasures.' Twenty years later, the second campaign against Goguryeo fails, Yang Xuangan's rebellion erupts, heroes rise in Shandong and Henan, the Tang Dynasty eyes Guanzhong, and the Sui Dynasty's fate plummets. A handsome Taoist priest leaves Jiangdu City, looking at the chaotic world and declaring, 'Since you cannot be a good supreme ruler, then I shall take your place!'
