Liu Rui was originally a modern person who loved ancient weapons and art of war, but once traveled through time, he became Liu Bei's eldest son. At this time, Lu Bu made a sneak attack on Xuzhou, and the situation was critical. Liu Rui relied on his past life memories and understanding of military art to turn the tide and help Zhang Fei defend Xuzhou. However, he faced constant intrusion from villains such as Lu Bu. In order to expand their territory, these forces used all means to prevent Liu Rui from helping Liu Bei consolidate Xuzhou and subsequently prosper the Han Dynasty.
When Liu Rui first arrived in the Three Kingdoms, he did not have enough control over the situation and was repeatedly frustrated when making strategic decisions. In addition, the Three Kingdoms were in troubled times with scarce resources and disputes between princes, which greatly restricted the development of his power. In the process of revitalizing the Han Dynasty, he also faced the dilemma of whether to compromise with certain forces to obtain resources, or to stick to his pure belief in revitalizing the Han Dynasty.
When recruiting talents, Liu Rui was misunderstood by some people as having impure motives, resulting in many misunderstandings. Every victory over the enemy is accompanied by the sacrifice of comrades, and victory is full of bitterness. The situation of the princes competing for hegemony is changing rapidly. He must grow his power within a limited time, otherwise he will be annexed by other princes. At the same time, some within the camp were divided over his strategy, leading to a crisis of trust and a deterioration in relations. However, Liu Rui relied on his tenacity to constantly resolve crises, recruit famous historical generals and counselors, and gradually move towards the goal of helping Liu Bei to rejuvenate the Han Dynasty.
