I Exchanged Marriage with My Sister, and I Defeated the Evil Star.

Song Xi was reborn on the day he received the decree of marriage. The imperial edict remains as before, requiring her and her sister Song Qi to marry the frail third prince and the evil lone star General Cui respectively. Faced with this overwhelming wealth again, Song Xi decided to change her relationship with her sister. In her previous life, she married the third prince Li Ruizhao as his concubine, but was diagnosed with infertility. Although she was not abandoned, she was not liked by the prince in the end and became the nanny in the prince's backyard. She died of exhaustion and toil. The younger sister Song Qi married Cui Mingcheng, a hussar general, but was killed within a year, killing one and two. Therefore, in this life, Song Xi felt that changing marriage was the most reasonable thing. Although the third prince is frail, his functions are normal in some respects. My sister is beautiful and fertile, so she will surely win your heart and have a successful career. And I want to marry Cui Mingcheng, the evil star who defeated his father at ten years old, his mother at fifteen years old, and his wife at seventeen years old. She was determined to wait for death, and she just wanted to die early and reach bliss. As a result, Bliss did not come, but the news came that Tiansha Lone Star had died on the battlefield and was wrapped in horse leather. Due to his outstanding military exploits, Cui Mingcheng was posthumously named Shun Guogong after his death. However, there is only one Duke's wife, Song Xi, in the Duke's Mansion, which attracts many wealthy wolves and leopards who want to take advantage of the family. Surrounded by a pack of wolves, Song Xi, who was pregnant with a posthumous son, no longer acted like a child. She wanted to fight the wealthy wolf to protect her child. But after fighting, she discovered that everything in her previous life was actually a conspiracy. Song Xi became angry: Then let's settle the old and new grudges together...
