Synopsis：After dying in action, modern special forces soldier Arthur Lancaster is reincarnated as the “useless” Third Prince of the Valoria Dynasty. Framed for assault by the scheming Crown Prince Victor and his cunning sister‑in‑law Isabella, he awakens his past-life memories and arms himself with modern weapons and tactics to exact ruthless revenge. When the arrogant kingdom of Viperia provokes and humiliates Valoria with outdated muskets, Arthur steps forward, unleashing tanks, fighter jets, and aircraft carriers to crush their forces. In the final decisive battle, a devastating nuclear strike wipes Viperia’s island realm off the map and restores the lost glory of his empire.
