I transmigrate to the final years of the Sui dynasty and become Li Yuan's illegitimate son. But before my father and brothers can even launch their rebellion, they are all killed in battle. All that remains are my four peerless sisters, who help me rebel. A young man rises to the ninth heaven, his heroic spirit piercing the sky. See the youth draw his bow once more: all his charm unfolds in the Tang dynasty!
