Cyberpunk Swordsman

A swordsman known as the Blood Immortal of Kunlun closes his eyes after completing his revenge. When he opens them again, he finds himself in a futuristic city junkyard, reborn as Ash, a humanoid cobbled together from scrap metal. It's a mechanical body with no dantian or inner energy... but what if he can channel electricity to perform martial arts? "I want revenge." In Akina, the girl who brought him back to life, he sees a reflection of his former self. Though he knows the emptiness that awaits at the end of revenge, he takes up his sword once more to protect her. In a world ruled by cutting-edge weapons, a swordsman wielding the martial arts of a bygone age has returned. (Source: Naver, translated)
