Under the blood moon in the sky, Shen Qingluan, the legitimate daughter of the Prince of Zhenbei, drank poisonous wine and fell into a pool of blood. Opening her eyes, she was seventeen again - the day when Marquis Yong'an broke off the engagement in public. In her previous life, she knelt down and begged him to stay, in exchange for a glass of poisonous wine. In this life, she tore up the royal marriage certificate with her own hands and walked away. The Shen family tried to silence themselves with poisoned wine, but the family law will serve? She pushed the clan elder into the hot incense burner in the Buddhist hall with her backhand. To avoid pursuit, she defected to the Zhao family, but she stepped into the vortex of fighting for the right to be the legitimate heir. Xiao Jingyan, the Marquis of Yong'an, blocked her with red eyes: "How dare you try marrying someone else." The cold-faced guard Lu Yuan put the tip of his knife to his throat: "Choose me or die." The mysterious master of the pavilion broke into the boudoir at night and handed over half a jade pendant: "Your mother's death is the work of that palace man." She won the first prize in one fell swoop, disguised as a man, and explored the secret room of the Supreme Harmony Palace at night, and found a yellowed secret letter under the dragon chair - her name was written on it. The three forces' daggers were aimed at her, but Shen Qingluan smiled and threw the secret message into the brazier: "In this life, I am the chess player." Whoever stops her will die.
