Qin Ming transmigrates into Piccolo at the time of the Saiyan invasion. Forced to kill Son Goku, he resolutely decides to start training Son Gohan and settle into a leisurely life as a stay-at-home dad (sort of).

Vegeta: “I work so hard while you slack off every day. Why can I never catch up to you? Damn it!”
Son Goku: “Gohan, come here and meet your real dad!”
