A Man dressed in black

As soon as the two arcs hit the wall and exploded on the wall, leaving two slash marks on either side.

Boom 

The walls shook upon the impact. That man turned back to see the walls. He was smiling, after seeing the amount of damage it caused. 

The cave was not that big, to begin with. It was about 30 meters in height and it was wide enough to accommodate 100 men. And the depth of the cave is unknown as it was all dark at the end of it. 

"Wow! Kid, you really are something!" the man exclaimed, grinning. 

"Where have you been till now?" 

Aragon was staring at him in disbelief. He had cut the attack in two, and he wasn't even scathed a little. And on top of that, he seemed to be captivated by him, not showing any fear. 

"Don't use them, just fight me with your sword skills," he asked Aragon. 

He had suggested that they should fight with only the sword and not to use any form or technique.
