Liu Rui traveled through time and became Liu Bei's eldest son, living in the troubled times of the Three Kingdoms, facing the strong obstruction of two powerful enemies, Cao Wei and Soochow. In order to maintain their hegemony, they use all means to undermine the growth of Liu Bei's camp. The protagonist shoulders the arduous mission of helping Liu Bei unify the Three Kingdoms and revive the Han Dynasty, but is faced with difficulties due to the huge power gap and limited time. In the process of developing power, the protagonist has to deal with the oppression of the social environment due to lack of resources and traditional concepts on the one hand, and on the other hand, he has to resolve misunderstandings and conflicts within the camp due to differences in ideas. For example, when implementing a new military training strategy, it was misunderstood by some generals as deliberately torturing soldiers, causing a crisis of trust. Although crises have been resolved time and time again with the help of modern knowledge, each victory comes with a heavy price such as the sacrifice of close friends. In the end, the protagonist successfully helped Liu Bei unify the Three Kingdoms amidst constant dilemmas and choices. However, facing the devastated land and sacrificed relatives and friends, the taste of victory was extremely bitter.
