On the northern frontier of Han, shaken by the roar of war, fate rolled two worlds into one. On the quiet hill of Jiuyuan, a young boy fell from a cliff for the sake of a single flower. At the same time, a modern teenager—comic enthusiast, KFC lover, and loyal dweller of high-rise buildings—was struck by a car and lost consciousness. But when his eyes opened again, he was not in a hospital. He was lying on rough earth, his frail body wounded… and surrounded by a group of Han children. In an instant, memories flooded his mind—new name, new destiny, new body. He was now Lü Bu. Not the legendary general, not yet. Instead, he was a twelve-year-old boy with a nearly shattered body, living on a frontier quietly preparing to break under a Hunnic invasion. When the thunder of hooves rumbled in the distance and the shout “The Xiongnu cavalry is coming!” split the village, he was forced to rise, even though his body was fragile and the world around him unfamiliar. Amid the press of war, fear, and the burning hopes of a family, he realized one thing: If fate had given him Lü Bu’s body, then he had to choose—hide and die young, or take the first step toward becoming a legend the world would one day fear. And the war… had only just begun.
