On the day Shen Qingtang, the legitimate daughter of the prime minister, married into the palace, she was framed by her stepsister Shen Miaoyin and her concubine Li Shi, and was thrown into the cold palace on the charge of "murdering the emperor's heir". She relied on the power and forbearance she had learned since childhood in the Prime Minister's Palace, secretly collected evidence, first exposed Li's fake pregnancy scam, and then revealed the truth about Shen Miaoyin pretending to be her legitimate daughter, and gradually promoted herself from a deposed concubine in the cold palace to a noble concubine. In the process, she and the emperor Xiao Jingheng went from "mutual testing" to "two-way redemption" - Xiao Jingheng was wary of the harem due to the shadow of his childhood, but was moved by Shen Qingtang's tenacity and sincerity; Shen Qingtang put aside his prejudice against "power" in the counterattack, and finally became the queen who protected Da Chu, realizing the pure love ending of "two people for life". Each chapter has the exciting points of "slapping the scumbag enemy in the face" and "reversing the situation", and the emotional line and the palace battle line are deeply bound.
