Li Chang, a modern-day transmigrator who has practiced Daoist cultivation since his early years, forms a sworn brotherhood in the Peach Garden with Liu Bei, Guan Yu, and Zhang Fei through a fateful encounter. Skilled in military command, political strategy, and Daoist mystical arts, he accompanies the army on its campaigns in Guangzong, Jizhou, cleverly defeats Zhang Jiao's sorcery and the evil arts of the Way of Great Peace, and repeatedly crushes the main Yellow Turban forces. Navigating the political intrigues of the late Han Dynasty, he carefully devises strategies to help Liu Bei build up his power, pursuing his original aspiration of restoring the Han Dynasty and bringing peace to the people amid the chaos.
