In her previous life, she was a deposed queen who died in a dry well in a cold palace. On the eve of her rebirth and canonization, she no longer competed for favors, but became a monk, changing her identity and returning to the imperial city - under the name of "Little Yinzi", she became the eunuch of the Supervisor of Ceremonies. This time, her opponents are no longer concubines, but powerful ministers, eunuchs and even the imperial power itself. From the cold palace to the ceremonial supervisor, from the deposed queen to the eunuch in charge of the palm, she will quietly lay out a chess game on the chessboard of power to overturn the dynasty.
