The modern girl Qin Wan accidentally traveled into the ancient painting "The Night Banquet at Jiang Palace" collected by her grandfather and became Leng Qingqing, the abandoned concubine in the cold palace. She relied on her mobile phone and modern knowledge to get around the court and capture the heart of Emperor Jiang Beiyu, but she was also involved in the rebellion conspiracy of powerful officials of the Zhang family. In order to protect his brother Zhongliang and his loved ones, Qin Wan teamed up with the emperor to set up a trap and killed Concubine Zhang with a passionate dance at the Mid-Autumn Palace Banquet, helping Jiang Beiyu regain the imperial power. She was severely poisoned and had only three months left to live. Her best friend Ma Shushu traveled through time with antibiotics to save her life. In the end, Jiang Beiyu appointed her as his queen and Jiang Shan as his retainer, and the two of them worked together to rule the world.
