Siheyuan: My Uncle Is the Heavenly Venerable of Morality

He transmigrates into the body of Yi Zhonghai's biological nephew. With a nephew at his doorstep, he's no longer a man without an heir. From then on, the courtyard has one more figure who throws his weight around. How will having someone to rely on change Yi Zhonghai? (The protagonist isn't a good person, and he's not the faithful type either. Once he's an adult, he'll do what adults do.)
