Fantasy: Kill All the Immortals in the World with One Sword

A blind man calculated by the immortal way, a system with a disconnected network, a pitch-black staff and knife, and a passerby destined to walk alone. In the process of practicing martial arts, he was constantly plotted by the so-called immortals. The immortals took away his eyes, but the martial arts gave him a pair of eyes. The immortal planned martial arts, and the rules could not accommodate martial arts, but he insisted on setting foot on the mountain top with his martial arts alone. Wearing black clothes instead of red robes, the sun and moon can swallow up the immortal dynasty in your eyes!
