Super Powers, Completely Self-Made

The human body has endless treasures, and where is the limit of martial arts potential? A world where supernatural powers prevail, and martial arts are abandoned. I sink the stone, turn it into a sacred stone, and reach the pinnacle of martial arts. A gentleman uses his body as a tool and uses all things as the way. Complete self-control, free the soul. I am not talented, but I am willing to break all laws with one physical body. This technique is mediocre and I can live in seclusion for thousands of years.
