Beyond the door was not the inside of a building, but a barren cliff side. There were training areas carved into the cliff side. What Xasha walked into was the largest of those training areas that didn't seem to have an end. He wasn't unfamiliar with this room as he walked over to a counter that had a wall of swords behind it.
He walked over and picked up a black metal sword and tumbled to the ground as soon as he picked it off the wall. He chuckled to himself as he realized that he may have bitten off more than he could chew.
The Struggle Sword had the same effect as the Struggle Bracelets. Xasha had the idea of combining training the Struggle Bracelets and the Struggle Sword and improving his body by training a sword technique simultaneously. However, the bracelets make the sword impossible to wield.
