Su Qinghan, the top agent of the previous generation "Night Falcon", died with the enemy in the final mission and was reborn as Shen Qingci, Queen of the Cold Palace of the Dajing Dynasty. The original owner was the legitimate daughter of the powerful Shen family. She was pushed to a lower position by the family but fell out of favor due to the reputation of being "unlucky" and was trapped in the cold palace to survive. Su Qinghan used the combat, intelligence, layout, and modern strategic thinking of the agents to break the situation as Shen Qingci. He survived from the cold palace to taking charge of the harem, and then intervened in the court. From testing each other to fighting side by side with the emperor Xiao Che, who tolerated evil and aspired to unification, he eliminated internal troubles, expelled foreign enemies, and finally helped Xiao Che to unify the world and become a legend of a generation of emperors and empresses.
