Shen Zhaoning, the orphan girl of the guilty minister, came back from the swamp and stirred up troubles in the government and the public in the name of a merchant. She teamed up with Xie Yansheng, the son of the Prince and Tutor of Qingliu, and worked step by step to reveal the truth about the queen's infanticide, the hidden treachery of the northern military power, and the Dragon Scale Seal guarded by the old eunuch. When Su Huaiyu's code book, Xiao Yunzheng's iron cavalry, and Pei Mingyi's witchcraft and poisonous fragrance all merged into her chess game, she finally stood on the golden palace - not to regain her surname, but to tear this cannibalistic system to pieces. This time, she was going to sit on the dragon throne.
