Once Shen Zhiyao traveled through time, she became an abandoned concubine in the cold palace, watching the strife in the palace with cold eyes. He originally wanted to be alone, but a volume of poems left behind attracted the attention of the emperor Gu Shutang. He was cold and suspicious, but he lowered his guard only in front of her; she was cold and taciturn, but quietly moved his lonely city with her wisdom and sharpness. When power schemes were raging, when life and death were at stake, he made an exception and showed mercy to her, and she changed his fate against fate. The cold palace is no longer a prison, but the starting point for their mutual redemption.
