Erha Is a Son-In-Law in Another World, and I Am Counting Money on Earth.

Uncle Dog travels back in time, first becomes a son-in-law, and then becomes a demon king. On the surface, he looks majestic, but in fact, it's all about deception. Just as the human envoy left, the strong man from the Blood Killing Hall's God Transformation Hall struck with his rear foot, and the knife almost hit his face! When all the demons were in despair, they saw Uncle Dog raising his paw to look at his watch and yawning: "Wow! Get off work at six o'clock in the evening!" The next second, Demon Lord Erha evaporated on the spot, leaving only blood to kill the palace master. He slapped the air with his palm and was messy in the wind. Gold Devouring Queen: "??" Princess Gray Moon: "???" Blood Killing Palace Master: "Are you a fake demon lord?! Give me back my killing move!"
