Lin Wanzhao, a peasant girl from the south of the Yangtze River, was elected to the palace as a promise because she looked exactly like the late queen. However, she was framed as a "conqueror" and sent to the cold palace because she refused to be attracted by the imperial concubine. She struggled to survive in the cold palace with the newborn third prince Xiao Jingheng. She used what she learned as a farmer to farm, collect herbs, and make wine in the wasteland of the Leng Palace. Not only did she provide for the food and clothing of her mother and her children, she also won over the maids of the Leng Palace by making herbal ointments and preserved fruits, and even cured the emperor's headache with herbal medicine. As her power grew, she began to fight back against the noble concubine's frame-up, and was gradually promoted from a cold concubine to a noble, a concubine, and a concubine. Finally, she helped the third prince Xiao Jingheng win the throne and became the empress of the mother-in-law world. She used her farming wisdom to reorganize the harem and achieve a counterattack in life.
