After transmigrating into a novel as Lin Zhixia, the wicked sister-in-law who poisoned her mother-in-law and met a tragic end in the original story, she opens her eyes to find herself facing a deadly mushroom soup. Meanwhile, unscrupulous people are trying to trick her into selling the Gu family's ancestral property, Qinglan Mountain, for a mere thirty taels of silver. She immediately tears up the mountain sale contract and uses her modern knowledge to uncover the value of the mountain's mushrooms and other wild produce, leading the villagers in mushroom picking, drying, and setting up workshops. When her opponents resort to malicious price cuts, cutting off the water supply, arson, and forging official deeds to seize the mountain, Lin Zhixia joins forces with her partners, stands firm on business principles, and fights her battles in court to protect Qinglan Mountain, which belongs to the entire village. She also repays old debts and breaks free from the tragic fate written for her in the original novel. Rather than relying on plot-driven handouts, she carves out a way to survive through her own abilities.
