The Tang Dynasty's Son-in-Law Physician

Mother-in-law: My daughter is breathtakingly beautiful, a peerless beauty blessed by heaven. Only someone like the Azure Dragon Medical Sage or the Lord of the Blood God Palace is worthy of her. You good-for-nothing, get out of here! Tang Long: Mother-in-law, those are all my other identities. My main job is being a live-in son-in-law, and my side job is being a peerless king. Mother-in-law: Why don’t you just claim you’re also the Great Tang’s emperor? Tang Long: Well... I really am!
