Pei Ce, a top student majoring in modern astronomy, traveled through time and became a young boy from a poor family. He was blinded by the backlash because of observing the stars at night and gaining insights into the heavenly secrets. During the palace examination, he wrote the article using star track as ink. The strange woman who can see the yin and yang in the dark dropped the cinnabar hexagram next to her annotation. At that time, the Prime Minister discovered that the disasters and undercurrents in the officialdom mentioned by the two men were all true and coincided with the late emperor's edict. However, they did not know that their opinions were incompatible with each other. If Pei Ce ascended to the throne, the woman would not survive the third watch; if the woman continued to live, Pei Ce would always fall into the cold kiln. The results of the palace examination are about to be announced, and the two are faced with a cruel choice of fate. Under the candlelight of the Gongyuan, the two ink scrolls devour each other. Amid misunderstandings and emotional entanglements, they wonder whether they can break the shackles of fate and find a glimmer of hope in their bitter relationship.
