Aideen Ruan, though a royal princess, was always unwanted due to the circumstances of her birth. Born blind to a hostage concubine, she possessed an intriguing beauty; however, her disability rendered her utterly useless to the royal family. Even when the struggling Count Crueder reluctantly agreed to take Aideen as his wife to secure the royal dowry, her life failed to improve. A year into their marriage, Aideen's inability to produce an heir sealed her fate. The princess was destined for exile to the Temple, consigned to spend the remainder of her days in isolation and abandonment. Contrary to her anticipations, instead of the Temple, Aideen found herself within the cold walls of Duke Tillian Valentine's castle. Duke Valentine, the last scion of the once-revered Valentine family that ruled the Kingdom before the "Fratricide Rebellion", now presided over the desolate Northern lands. Faced with fear and confusion, Aideen expected her life to perpetuate its cycle of misery, only to discover that Duke Valentine might hold the key to a new opportunity, a chance at a life she had never envisioned.

"I... have obtained the golden ultimate occupation, 'God of Martial Combat'!" The largest urban agglomeration in the world, a night of torrential rain. On the ground, countless Killing Ghosts and Fighters fought to the death, while hordes of metal Mechas and Biological Armors exploded and self-destructed. Blood and flame intertwined, plunging everything into primordial violence and chaos. Atop a high tower, Bai Xiao stood silently amidst the rainy darkness, like a stiff and terrifying statue. His crimson eyes looked down below, restrained yet bloody, cold yet hiding madness. He leaped down with his trench coat wildly dancing. The God of Martial Combat descended upon the final battleground! A cold voice echoed across the city skyline. "Next, I will kill everyone present! If you have the ability, try to stop me..." A modern city of extravagant luxury, an era of entertainment and consumption supreme. Beneath seventy years of peaceful façade, lied another mad and bloody Inner World. Fighters, masters of their martial traditions, and Killing Ghosts, controlled by combat modes, engaged in a frightful, relentless slaughter. Metal Mechas with terrifying energy and Biological Armors extracted from monstrous cells commenced a brutal struggle between old and new technologies. In this era infested with machinery and altered by external entities, to proclaim the power unique to humans might be an unimaginable romance...
