The concubine Su Jinyan's biological mother died young, and she was bullied by her aunt and sister in the Prime Minister's Mansion. In order to protect herself, she was forced to enter the palace as a low-level promise. On the eve of entering the palace, she unexpectedly obtained the "Glass Mirror" left by her biological mother. The mirror contained two golden fingers, the "Psychic Peeping Technique" and the "Baicao Jing". In the deep palace, she pretends to be a pig and eats the tiger, using her golden fingers to resolve fatal crises many times, secretly making allies and accumulating strength. From the promise that no one cared about to the concubine rising step by step, she not only had to deal with the open and secret attacks of the concubines in the harem, but also dealt with the game of the forces of the previous dynasty. As she gradually approached the center of power, she discovered that there was a mystery behind the death of her biological mother, and her entry into the palace was even more involved in a huge conspiracy related to the change of imperial power. In the whirlpool of love, hatred and power, Su Jinyan used intelligence as a chess piece and human hearts as a pawn, and finally counterattacked and reached the top, but she also faced the difficult choice between family and love.
