After the fall of Yan, Prince Yan Shuo was sent to Dachu as a hostage. On the surface, he acted as a docile and forbearing proton, but in fact, he concealed his family's "Eighteen Swordsmanship of Yanyun" and worked step by step in the enemy's court and in the rivers and lakes. In the early stage, he was bullied by the evil slaves in the palace due to his low status, and established his power by killing the evil slaves with a knife; in the middle stage, he rescued Princess Chu Ling at a hunting banquet, revealing part of his strength, and gradually gained the trust of the Emperor of Chu. The highlight is the contrasting performance between the "docile proton" and the "ruthless swordsman", the cool point of relying entirely on swordsmanship and strategy without a golden finger, and the ultimate counterattack from proton to emperor.
