Son-In-Law of the Dragon King

Following the orders of his parents and the words of his matchmaker, after his parents died, Ding Yi hid his identity and married into the Su family as his son-in-law in order to avoid his enemies. After three years of marriage, he acted like a cow and a horse without any complaints, but—— His sincerity was thrown to the ground and trampled by the Su family! He was working hard to make money outside, but he saw his wife having an affair with someone else! Now, the three-year period has come and the Dragon King has returned to the throne. I, Ding Yi, am no longer worthy of this son-in-law! My master holds the best alliance in the world and is famous overseas My senior brother is an expert in medicine and martial arts, and he kills people invisible. My senior sister is a genius in business and is as rich as anyone in the country. Someone throws mud at me, I use his ashes to grow lotus flowers!
