I'm Cultivating Immortality While Everyone Else Practices Martial Arts

You practice martial arts, I cultivate immortality. Su Ze, carrying a cultivation system, transmigrates to a world where spiritual energy has revived and martial arts are prevalent. What? Grandmaster martial arts, supreme secret manuals, powerful blood and qi, and strong spiritual power? Sorry. I start with immortal techniques; a single strike can create a blade hundreds of meters long. My spiritual power has only barely managed to condense a nine-zhang-tall primordial spirit. This is the story of a cultivation master navigating the world of martial arts.
