A man gets swallowed by a monster and accidentally becomes something else entirely. From that moment, he's caught between the collapse of an empire and forces that see him as a weapon, not a person. The black dragon power isn't salvation, it's the thing that makes him dangerous to everyone who wants to use him, including himself.
Chaos grips the Tang Dynasty as the An Lushan Rebellion tears through the empire, and monstrous creatures ravage the war-torn landscape. Li Haobai leaves his home in Bashu with a soldier's ambition: reach the front lines and prove his worth through heroic deeds. Before he can fulfill this dream, a monster swallows him whole. Instead of death, something extraordinary happens. Within the creature's body, Li Haobai encounters the guardian of the dragon's veins, an ancient force bound to the earth itself. Their collision triggers a fusion, granting him the power of the black dragon and transforming him into something far more than human. Armed with this newfound strength, Li Haobai emerges into a world of competing factions and hidden agendas. Warlords, supernatural entities, and power-hungry schemers all want control over what he has become. His journey from a hopeful soldier to an unwilling player in a larger game unfolds through battles, betrayals, and the discovery of just how deep the conspiracy surrounding his new abilities truly runs.
