I Descended from Kunlun

Thirteen years ago, Li Muden and his grandfather survived by scavenging trash until the old man passed away, leaving only a marriage contract to a wealthy family. Desperate, Li Muden was taken away by the Kunlun immortal Yun Yangzi. Thirteen years later, having returned from cultivation, Li Muden finds his fiancée is now an adult. While others compete to become wealthy widows' sons, Li Muden's first act upon descending is to break the engagement. He secretly vows: 'A widower's son is impossible for me. Either I break the engagement or I take your surname. If there is a wealthy family in this world, it must be built by my hand. If there is a noble lineage, it must be passed down through my surname.'
