In order to find out the cause of the death of his parents, Jiang Han, a disciple of Zhongnan Mountain, followed the orders of his sloppy master, Taoist Master Qingxu, and went down the mountain with three marriage certificates. He was required to marry one of the fiancées and give birth to a disciple for his master. He first chose Yan Luoqi, the eldest daughter of the Yan family, the richest man in Weicheng, but she was despised by everyone in the Yan family because of her background, and was also made things difficult for her by Yan Luoxin, the second daughter of the Yan family. In order to test him, Mrs. Yan asked him to recover the 1 billion project payment owed by the Tianlong Group to the Yan family within three days. Jiang Han successfully completed the task with the help of his extraordinary martial arts and the help of Wang Shiyu, the eldest lady of the Tianlong Group whom he accidentally met. However, Yan Luoxin pretended to take the credit, and the engagement contract was unilaterally annulled by Yan Luoqi.
