😋I recommend the following two novels to you: 1. " Biography of Marquis Wen at the End of Han Dynasty ": This is a short biography of a character. It tells the story of Lu Bu's life. He doesn't breed horses. The plot is slightly embellished. It suits your needs. 2. " Dimensional Renderer ": This is a derivative doujinshi novel. The main character is a renovation worker. He doesn't cheat, set up any tricks, or play a stallion. He fits the cold and ruthless main character you want. I hope you like my recommendation.😗
