Master of the Martial Arts Library

Ha So-chan, the bastard of the Ha family, lived a life full of despair. Even though he dedicated his life to training, the only thing he received was laughter and a destroyed dantian.
Then came the miracle: ‘Congratulations on becoming the master of the martial arts library.’
“The world will remember my name.” Thus, begins the story of the greatest teacher and the greatest swordsman, who is destined to conquer all.
