The Richest Son-in-Law in History

Does a live-in son-in-law have to swallow every insult? No, he can be treated like a king! Ning Fan: “Mother-in-law, bring me some water to wash my feet!” Mother-in-law: “Coming right away.” He is the Qin family's live-in son-in-law. Everyone thinks he's a useless freeloader, but they have no idea he's richer than a nation and powerful enough to rule the world!
