I recommend Song Zhen to you. This was a historical novel from the Song Dynasty to the Ming Dynasty. It told the story of how the protagonist traveled to the Song Dynasty and was kidnapped by the Jin people. For the sake of his mission and his own purpose of saving the world, he got involved with the number one traitor, Qin Hui. In the story, the protagonist not only showed strong willpower and killer skills, but also brotherhood and sonorous elegy, which could be said to better reflect the theme of love and righteousness. I hope you like my recommendation.😗
