Cui Lin is the youngest aunt in charge of the palace. She has survived for ten years in the cannibalistic Forbidden City. She is familiar with all the secrets and unspoken rules in the palace. She saved enough money to prepare to retire from the palace. However, on the eve of leaving the palace, she was treated as a pawn and sent to the bed of the dragon by the doting concubine. Afterwards, she even tried to kill people and silence her. Cui Lin knew that there was no way to retreat. Now that she was in the game, she no longer served others, but wanted to be the master of the harem. She took advantage of her familiarity with the loopholes in the palace rules, her control of the concubines' weaknesses, and her precise understanding of the emperor's preferences to succeed at every step. She didn't talk about love, she only talked about interests. She took advantage of the emperor's guilt and desire to conquer, and trampled under her feet one by one the concubines and queens who were once aloof. There is no golden finger in the whole process, and it all depends on high IQ games and ruthless methods. In the end, the emperor is killed, his youngest son is supported to ascend the throne, and she becomes the queen mother at the pinnacle of imperial power.
