This was similar to the blade skill of the Blade God. Yeowun then realized that this old man was related to the Blade God Six Martial clan. Yeowun used the second formation of the Sword Force of the Sky Demon. The sword was coming from a weird angle, but Yeowun knew where it was coming from already so he defended against it easily.
The old man's eye grew large from shock. The movement wasn't something that could be predicted but Yeowun defended easily as if he knew it from the beginning. Yeowun struck the sword down and spoke.
"You're from the Blade God Six Martial clan."
The old man's eyes shook from shock. He had snuck into the territory of the Forces of Justice, so he refrained from any formation that might resemble that of the Blade God's skills but he revealed just one movement.
'What? Does he know our clan's martial art?'
