Widowed daughter-in-law Li Xiulan served her paralyzed mother-in-law for ten years, but during the family property division, she only received an old copper key, facing mockery from both elder brothers-in-law. Before passing away, the mother-in-law secretly arranged a layout; the key was actually the inheritance token of the Huizhou Wang family's billions in wealth. Following silver bracelets and old photographs, the mother and daughter traced their way to the Huizhou old house, uncovering the mother-in-law's true background. Greedy brothers rushed over to seize and livestream rumors, but were instead publicly slapped in the face by a handwritten will and villagers' testimonies, reaping what they sowed. Li Xiulan signed a 300-million cultural tourism project, revived the ancient tea industry, and fulfilled the mother-in-law's dying wish of returning her roots to her homeland.
