Jiang Xiaobai was an avid modern-day enthusiast of Three Kingdoms history. After a bizarre transmigration, his soul ends up in the body of a bandit chieftain with the same name. He now faces a desperate situation: the bandits of Woliu Mountain are riddled with injuries, short on provisions and money, watched by government troops, and driving merchant caravans away.
To survive and build his strength, Jiang Xiaobai draws on his knowledge of the Three Kingdoms and his own ingenuity. He abandons the traditional practice of robbing people and resolves to train an elite force, making a name for himself in this chaotic age. When he learns that the powerful local lord Liu Da is oppressing the people and recruiting troops, and that a convoy carrying provisions will pass through a nearby valley by Woliu Mountain, Jiang Xiaobai swiftly recognizes the perfect opportunity to strengthen his forces.
He carefully lays his plans and sets a clever ambush, leading the bandits into a fierce battle with Liu Da's escort. Thanks to flexible tactics and the men's fearless fighting, they defeat Liu Da's forces, seize their provisions, and recruit the surrendered soldiers. After this battle, Jiang Xiaobai establishes unquestioned authority among the bandits, and the power of Woliu Mountain grows.
From Woliu Mountain as his starting point, Jiang Xiaobai will continue to display his great talents in the turbulent Three Kingdoms era, maneuver among the various powers, and embark on a legendary journey from mountain bandit king to contender for the realm, forging his own hegemony in the Three Kingdoms.
