Shen Zhao was forced to replace his dead sister and marry the enemy general Lu Heng, becoming a substitute for his hatred. She looked down and looked down, but in the dead of night she was reading the secret files on his desk; he looked at her coldly, but he paused for a long time in front of her blood-stained cuffs.

Lu Yan's silence, Han Siyan's calculations, and the old woman's embroidered handkerchief were all tearing apart the chess game silently. The day when the veil is lifted is not the end of hatred, but the beginning of the storm between the two countries.
