During the Tianqi years of the Great Chu Dynasty, the imperial power was controlled by powerful officials Xiao Clan, and conspiracies arose in the harem. After the abandoned concubine Lin Wanzhao was thrown into the cold palace, she unexpectedly discovered the secret secrets of the previous dynasty and the corrupt accounts of powerful officials. With ruthlessness and strategy, she climbed out of the cold palace and was promoted step by step to the position of female official. She dealt with concubines and powerful officials, exposed conspiracies, slapped villains in the face, and finally supported the young emperor to ascend the throne and became the controller behind the scenes. At the same time, she and Xiao Jingheng, the border general who had deposed her as a commoner (who later returned to Beijing to seize the throne as emperor), used each other to love each other. The two worked together to end the chaos of powerful ministers, realize the concentration of imperial power, and write a well-matched palace-wall love.
