My Sister-In-Law Has to Change Her Marriage? Why Are You Crying When I Marry the King of War?

My sister-in-law and Lin Yulan were reborn together. In this life, the sister-in-law wanted to marry the only male in the eldest family who was later found by the Rongguo Duke's mansion, and to become the Duke's wife with unlimited glory in the future and respected by everyone, so she made a bad plan and got into the sedan chair of the Wuwei Marquis' mansion. The notorious Marquis Wuwei in his previous life had an accident and his legs were disabled not long after getting married. He became violent and arrogant, and later died in a fire. Naturally, his title was also lost to his second wife. The sister-in-law sneered, "It's your turn to feel the long nights, being a widow, and being ridiculed and trampled upon! Why do you, a concubine, have a better life than me?" Unexpectedly, Marquis Wuwei became a maniac who doted on his wife, and the love between his husband and wife led to great success. However, the only male of the eldest son's house who was brought back by the Rongguo Duke's Palace, because he grew up in the private market, had no rules, no sense of education, and was vulgar, made countless jokes, and made the Rongguo Duke's Palace a joke. Not to mention his endless glory, he even lost the qualification to inherit the title! My sister-in-law was so angry that she felt so regretful that her intestines turned blue. Lin Yulan smiled faintly. God knows how much effort she put into her last life to prevent her useless husband from being rejected by his aunt's mother and to become a qualified heir to the Duke's palace. In the end, she ended up with a superficial appearance of having her teeth knocked out and her blood swallowed. That man is just a selfish, greedy and shameless white-eyed wolf! The Rongguo Duke's mansion is just a den of wolves that eats people but doesn't spit out their bones! Since my sister-in-law is rare in this life, I'll just take it. For her, marrying anyone is better than marrying that person! Unexpectedly, God would treat her well in this life and give her a husband who doted on his wife, was young and handsome, and was rich and powerful!
