The special forces accidentally traveled through time and became Guan Xing, the second son of Guan Yu. They were shocked to realize that they were in the 24th year of Jian'an, and there were only three months left before Guan Yu defeated Maicheng! He is familiar with history and tries to rewrite destiny. First, he used astronomical warnings to urge Zhuge Liang to mobilize troops to Yiling; he also used secrets from his past life to advise Guan Yu and offer three strategies. However, Mi Fang rebelled and surrendered, and the situation took a turn for the worse. Guan Xing formed the "Night Owl Camp" and skillfully used modern tactics to bomb merchant ships, instigate rebellion against the enemy, and also stockpile grain for defense in Maicheng. Faced with Guan Yu's determination to face Ju's dilemma, he used the people's support as a shield to turn the tide. In the end, guerrilla tactics were used to attack Jianye, disrupt Soochow, successfully rewrite the war situation of the Three Kingdoms, reshape the direction of history, and open a new era of the Three Kingdoms.
