Sun Erniang, a heroine of Jianghu, entered the palace alone to investigate the unjust case of her father, General Sun, collaborating with the enemy. She doesn't know how to fight in the palace, but she knows martial arts; she doesn't know the rules, but she has tricks in the world. On the day she entered the palace, she was punished and sent to the cold palace for spitting on Concubine Shen's car. However, she accidentally discovered half a jade pendant and a secret passage leading outside the palace. Deep in the secret passage were hidden the old ministry roster left by her father, half a tiger talisman and key clues to the collaboration with the enemy case.
Emperor Xiao Yan was deeply sinister, and at first he just wanted to use this "wild and untamable" woman to stir up trouble in the harem and contain the powerful Shen family. He brought her out of the cold palace and promoted her from the dressing room to the noble. The two fell in love while being used and tested. However, the deeper Sun Erniang investigated, the more she discovered that the truth was related to the emperor. The chief eunuch's words "Your Majesty's acquiescence" before his death drove her into the abyss. In order to save her life, the emperor personally pushed her back to the cold palace and said coldly: "I never believed in you, you are just a chess piece."
Sun Erniang cut off her ruthlessness, faked her death and escaped, returning to the world. The emperor regretted it so much that he put aside his imperial dignity and chased his wife thousands of miles away. Sun Erniang continued to investigate the case with all her strength, and the Queen Mother's mastermind came to light, and finally the villain King Yu revealed his true face. The unjust case of the Sun family leads to a major case of collaborating with the enemy, and the Jianghu and the imperial power face off. The emperor issued an imperial edict for her, overturned the verdict for her, offered her Zen status, and even protected her with his life. When the truth came out, the two of them were separated by rivers and mountains and blood debts. Sun Erniang asked: "I want your kingdom to change hands. Will you agree?"
From an abandoned woman in the cold palace to a virtuous queen, from a revengeful orphan to the beloved of the emperor. Sun Erniang kept her true heart and the true feelings that had been broken and reunited.
A sword in the rivers and lakes can cut off grudges; a promise in the palace can save the rest of life.
Purpose: Can a woman from the world not only reverse the family's case in the cannibal palace, but also keep her true heart from being swallowed up by the imperial power?
