My Sister-In-Law Is so Heartless

[Sister-in-law with Two Faces vs Uncle Flower of the High Mountain] The eldest sister-in-law of the Fu family entered the family at the age of ten, became a widow at the age of twelve, and spent twenty years serving her parents-in-law. Her deeds were rewarded by the royal family, who gave her a chastity arch on her twentieth birthday. But that day, she secretly sneaked into her brother's hot spring pool. The new head of the family, Zhilan Yushu, is noble and powerful. Only by clinging to him can her wishes come true. So every day when Fu Beisi was at home, his widowed sister-in-law would personally undress and bathe him, doing everything in a meticulous and gentle manner. But just when he was thinking about arranging a new identity for her, the always gentle and amiable sister-in-law actually ran away. When he found someone again, he wanted to crush their jaws: "It turns out that the widowed widow is a ruthless and unrighteous widow. I have learned a lesson." ①The female protagonist seduces the male protagonist just for revenge. ②The dynasty is empty. ③Sc. ④ Dog blood. Intention: truth, goodness and beauty.
