Nuclear Blade Technique: One Slash, One Kill”

Special forces soldier Jin Quan devoted his life to the battlefield, but betrayal from within turned him into nothing more than a living coordinate—used to guide a missile strike that ended his life in fire and radiation. Yet death was not the end.

When Jin Quan opens his eyes again, he finds himself in a completely different world. Stripped of everything, he awakens in the Lower City—a place of despair where the lowest-class humans are treated as disposable mining slaves. Weak, starving, and abandoned, his second life seems destined to end before it even begins.

But at the brink of death, something awakens within him. The radiation that destroyed his body in his past life has fused with his very soul, granting him an extraordinary innate ability. At the same time, he inherits the rare and powerful class of the “Demon Swordsman.”

From the shadows of the slums to the arenas where the strong rule, Jin Quan must carve his way forward. Armed with terrifying new powers and hardened by betrayal, he begins a relentless struggle against the so-called God’s Chosen—those who see themselves as untouchable rulers of this world.

This is the story of a broken soldier reborn in a cruel world… a man who was once a weapon, now becoming a legend.
