Not Your Son-in-Law

Thirteen years ago, Li Muchen lived hand to mouth with his grandfather, scraping by on whatever they could scavenge. Then his grandfather died suddenly--leaving him nothing but a single sheet of paper: a marriage contract with a powerful elite family. With nowhere to go, Li Muchen was taken away by a passing Kunlun immortal, Master Yunyang. Thirteen years later, Li Muchen returns from Kunlun--now a cultivator--and the first thing he does is call off the engagement. Being a live-in son-in-law? Not a chance. Either the marriage is canceled... or you take my surname. If this world is going to have great clans, then they'll be passed down under my name.
