A modern-day office worker unexpectedly transmigrates into a book, becoming Jian Ning, the overweight, lazy, and gluttonous shrew in the story. Upon waking, she receives a divorce letter from her young husband, Xiao Yan, and the original character is destined to be abandoned and die a tragic death. To save her life, Jian Ning tears up the divorce letter and resolves to turn over a new leaf, accidentally unlocking a cheat ability that grants her extraordinary natural strength. Every day, she ventures into the mountains to gather medicinal herbs and catch fish, invents wildly popular explosive water balls and fish soup noodles, and partners with Xiao Yan to supply the town's restaurants and make money. While keeping her appetite in check and steadily losing weight, she also deals with the harassment of troublesome relatives. Working together, the couple dig fishponds and build a new brick house, expanding their business to the prefectural city. Once a fat shrew despised by everyone, Jian Ning builds a thriving family business with her own hands and joins her young husband in pursuing a happy future.
