Master comes down the mountain, I don’t know martial arts, but I am an immortal

Introduction: Thirteen years ago, Li Muchen and his grandfather depended on each other and made a living by picking up rags. Grandpa died suddenly, leaving him only a wealthy marriage contract. Helpless, he was taken away by the passing Kunlun Immortal Yunyangzi. Thirteen years later, Li Muchen returned from Kunlun to cultivate immortality, and his fiancée had grown up. While others were vying to be the son-in-law of a wealthy family, the first thing Li Muchen did when he came down from the mountain was to break off the engagement. It is impossible for a surrogate son-in-law to be a surrogate son-in-law. He must either break off the engagement or take my last name. If there is a wealthy family in this world, it should be built by me. If there is an aristocratic family in this world, my surname will be passed down to future generations. [Market Fairy]
