Gu Changning, a live-in son-in-law who was bullied by his mother-in-law and relatives of the Lin family, made a living by delivering food. When he completed his 500th takeout order, he accidentally activated the Shadow God of Cookery system. Through five-star reviews, he can unlock the God of Death skills such as dismemberment, precise poisoning, and teleporting kitchen knives. He counterattacked from a useless son-in-law to a feared "God of Killing Eater" in the underground world. He relied on the system to clean up the forces of Zhao Qiankun, the underworld boss who oppressed the Lin family, and fought side by side with his wife Lin Wanqing, who loved him deeply, to reveal the truth about the hell contract behind the system. The couple shared a long life, ascended hand in hand, and finally embarked on a new journey to judge the gods.
