Reborn After a Tragic Death, I Marry the Scumbag Emperor's Uncle on the Spot

In her previous life, she was the daughter of a military family. She helped him ascend the throne, only for him to wipe out her entire family. Reborn on her wedding day, she changes course and marries her scummy ex-husband's uncle, the emperor! Everyone laughs at Yu Guiwan for marrying a sickly man, but to their surprise, Xie Sui's health improves after their wedding! When Yu Guiwan kills, he hands her the knife. When she sets fires, he fans the flames. Everyone in the capital knows Yu Guiwan is utterly spoiled by her husband. Her scummy ex-husband regrets everything, but Yu Guiwan kicks him to the curb. Yu Guiwan: “We agreed this was just a partnership. Shouldn't we get divorced now?” Xie Sui: “All right.” Xie Sui agrees readily, then turns around and hangs himself.
