I recommend the following two novels to you: 1. "The Strongest System to Dominate the Three Kingdoms". The protagonist of this novel traveled through the Three Kingdoms, from weak to strong, slowly developing his territory. Finally, he used his power and martial arts to defeat the vassals one by one, and finally won the world. Although the main character had the help of the system, unlike other transmigration novels, he also encountered failures and setbacks in his growth process, and he grew from them. 2. "The Three Kingdoms: From Yiling onwards, Liu Bei and I will unify the world." The protagonist of this novel was reborn as Liu Bei's eldest son, Liu Chan. He realized that history was too scary and he had to help his cheap father and unify the world as soon as possible. The main character's experience was not smooth either, but in the end, he used his intelligence and courage to help Liu Bei unify the world. The above two novels meet the requirements of the title. I recommend them to you. I hope you like my recommendation, Mwah ~😗
