On the night of the bloody edict, Jiang Yejin escaped from the imperial city with the remaining scrolls. He was guilty of a crime that reached heaven and was homeless. He found a blood-stained jade hairpin in the ruins, which was exactly what Liu Susheng left behind - it was the token she had hidden in her sleeve when she was sewing clothes for him. The two of them once guarded the secrets of the country, but now one is a fugitive prisoner and the other is a ghost in the palace. When the court hunted Jiang Yejin in the name of "regicide and rebellious ministers," Liu Susheng, as a queen, burned incense and played music in front of the emperor, and quietly conveyed the secret map with a song "The Ballad of Broken Clouds." They no longer recognize each other, but use their lives as a chess piece to reconstruct the broken mountains and rivers in blood and fire.
