Ten thousand years ago, the fairy king Muyun was secretly accounted for by holding the figure of Zhuxian, and after a thousand years of sleep, he woke up in the famous “Useless Muyun” of the Southern Yun Empire in the mainland of heaven. When Muyun first woke up, he was deliberately harassed by Miaoxianyu. Muyun easily completed Miaoxianyu’s trap and provided more alchemical techniques by analogy, so that the alchemical masters outside the door couldn’t match him.Returning home, Mu Yun learned that he would marry Miss Qin Qin Mengyao. Qin Mengyao is cold and poisonous, but cannot live until he is 20 years old. The marriage was only for the benefit of the Qin family. However, under Mu Linchen’s persuasion, Mu Yun agreed to this family problem on alchemical terms.
