Into the canyon, again.

Aragon finished wiping his face clean of the blood. He then turned to face the crooked path entering the canyon. He was all exhausted from hours of fighting. And the slaughtering technique that he performed drained him completely. It was the main reason he got out of there as fast as he could. The mana required to use the technique was excessive. He knew about the method for increasing one's mana capacity, but it required very expensive materials. When he was in the library up in the mountains, he read books related to mana.

That was what he trained for years with his grandmother. Although she left, he decided that he would practice it every day. For the last few weeks, he has been missing morning practices.
