In the winter of the 23rd year of Yongchang, a death decree was sent to the cold palace - the deposed queen Gu Qingyuan waited for a pot of poisonous wine from the heartless emperor. Three years ago, she was the most noble queen of Daliang, but because of the emperor's words, "The Shen family is treasonous," she saw her entire family wiped out with her own eyes. The moment he drank the poisoned wine, his nails dug into his flesh, and his survival instinct burned away the last of his innocence. The man who once promised to protect her for life is now holding Xinhuan in his arms and wants to kill her.
Take advantage of the enemy's tactics and escape from death. When Gu Qingyuan returned to the palace as a draftee, the cold-blooded emperor who had crushed her into dust in the past did not recognize her, but was instinctively attracted to this mysterious and tenacious woman. However, this time, what she wants to seize is not the worthless love of the emperor, but the dragon chair under his seat, the country that he wants to protect even if he kills all the Shen family.
She worked step by step, starting from the lowest palace maid, fighting for favored concubines, redressing unjust cases, and overturning old cases. In this man-eating palace, the only variable she encountered was the guard who was always silently guarding her. He had seen her in the most miserable state, but he was still willing to die for her. With the flames of revenge on one side and forbidden affection on the other, she must make a choice on the tip of a knife.
It wasn't until the emperor forced her into a desperate situation again, until the chess game she had spent half her life setting up was seen through, that he finally asked her with red eyes: "Who are you?" She slowly wiped the blood from the corner of her mouth under his trembling eyes, and smiled thrillingly: "Your Majesty, I am here to collect debts."
This deep palace is a cage made of gold. And what she had to do was smash it with her own hands.
