Su Tang, a graduate student in the history department, traveled through time and became an abandoned concubine in the cold palace. Faced with the desperate situation of being abandoned, she did not cry or make trouble, and relied on modern knowledge to grow medicine and weave a web in the cold palace. When Emperor Xiao Yan was defeated at the border and the court overthrew, she offered her salt and iron reformation and firearms blueprints in exchange for regent power. In the past, the abandoned concubine worked step by step, wooed the imperial army commander Lu Mingyuan, instigated the rebellion of the imperial concubine Zhao, and backhandedly forced the emperor into a desperate situation. When Xiao Yan knelt in the snow and begged her to turn back, Su Tang just chuckled: "Your Majesty, what you love is not Su Tang, it's a power you can't control."
