After Giving Her Contraceptives, the Mad Prince Turned White-Haired Overnight

Shen Ning, the legitimate daughter of the Shen family's first branch, was reborn after a tragic death. In her previous life, her father died in battle, her two brothers were ambushed, her younger sister Shen Wan was found dead in the street, and she was forcibly taken by Prince Regent Xie Linyuan on her wedding day to the Fourth Prince Xie Xuanchen. Believing her eldest sister Shen Rou and Xie Xuanchen, she became their pawn against Xie Linyuan. She caused the death of his imperial concubine mother, forced his sister Princess Chaoyang to a tragic marriage, and led to his own demise pierced by arrows on the city wall. Later, she was drowned alive in a lotus pond by Shen Rou. After death, her soul drifted for five years, witnessing the truth: Shen Rou was not her biological sister, the mountain bandits at Putuo Temple were hired by Xie Xuanchen, and Xie Linyuan was the only one who truly loved her. Her remains were later buried together with his.

She woke up on the night of her rebirth in the meditation room at Putuo Temple, where Xie Linyuan was detoxifying her with aphrodisiac. In her previous life, she had mistakenly believed Xie Xuanchen was the one and secretly left. This time, she realized the man was Xie Linyuan, who seemed colder and rougher than before, even ordering her to drink contraceptive soup. She suspected he was also reborn. Overwhelmed by guilt and sorrow, Shen Ning decided to change her fate. When her maidservant Bai Zhi arrived, Shen Ning learned that Shen Rou had already made arrangements to leave the mountain at night, claiming mountain bandits were nearby. Knowing this was the trap where Xie Xuanchen would pretend to rescue her, Shen Ning took action. She killed Granny Gui, the trusted nanny who had colluded with Shen Rou in her previous life, and dressed the corpse in her own clothes. She sent Bai Zhi to hide in Xie Linyuan's meditative room for safety, then jumped off the moving carriage, injuring her ankle but avoiding the ambush.

Later, she watched from a distance as Xie Xuanchen and Shen Rou attacked the carriage, mistaking Granny Gui's body for Shen Ning. Xie Xuanchen was stabbed while holding the corpse, a wound he had planned for himself. Shen Rou was stunned by Shen Ning's sudden appearance and harsh words. Returning to the Shen manor, Shen Ning discovered a box under her bed containing love letters forged in her handwriting, one of which was a secret meeting note from Ning Congwen, a dissolute son arranged by Shen Rou to ruin her reputation. In her previous life, these letters caused her sister Shen Wan's engagement to be canceled. Shen Ning burned the originals, had Bai Zhi retrieve a hidden letter from a dog hole, and began to forge new letters to turn the tables. She bathed, seeing the bruises left by Xie Linyuan, but resolved to trust only Bai Zhi and proceed with her revenge alone.

Determined to protect her remaining family, she vows to send all who harmed the Shen family in her previous life to hell. This time, she will not be deceived by Shen Rou and Xie Xuanchen, nor will she repeat her mistakes with Xie Linyuan. Though the Prince Regent may resent her, she must forge her own path and prevent the tragedy that once befell her father, brothers, and sister. With the knowledge of the future, she begins to dismantle the schemes one by one, starting with Granny Gui's death and the exposed trap at the temple. The battle ahead is fierce, but she is ready.
