Sword God of the Demonic Cultivation

I want to be like the great swordsman! A child born from the secret art of apostasy, Jang Seol becomes the disciple of Hwangbo Cheolseung, the swordsman who was once the confidant of the leader of the martial arts world, and begins to take his first steps as a martial artist. He has one ability...

This child can read the memories of iron.

Jang Seol grows stronger with each weapon that passes through his hands. He throws himself into the chaotic world of martial arts to find the 'Ten Great Records of the Martial Arts World', known as the legend of martial arts!
