Modern office worker Li Daoyi accidentally transmigrates after a business dinner, waking up in the body of a poor orphan in the late Eastern Han dynasty. With the Yellow Turban Rebellion just around the corner, he is trapped in a desperate age where human lives are worth less than grass. At the critical moment, the Late Han Dragon Soars System quietly activates, giving him a glimmer of hope for survival.
With the System's help, Li Daoyi starts by learning to survive in the wilderness, hunting to improve his livelihood and mastering basic martial arts. When the Yellow Turban Rebellion reaches his village, he is entrusted with the task of organizing the villagers to build defenses. Using his wits and courage, he defeats the bandits who attack, earning fame with a single battle.
As his reputation spreads, refugees rally to him and talented men join his cause. The arrival of the strategist Chen Mo makes him even more formidable. From protecting the people of a single village to uniting the surrounding forces, Li Daoyi combines modern knowledge with the System's support, advancing cautiously on the Three Kingdoms stage where heroes vie for supremacy. Thus begins his legendary rise from a nobody at the bottom of society to a hegemon in a chaotic age.
