Battling A Wind Sovereign

While the man's children were worrying about their father's abrupt disappearance, Grey had taken him some kilometers away to ensure their battle wasn't noticed by anyone, at least not as soon as it started.

The moment Grey and the man appeared on the mountaintop, Grey didn't hold back and attacked in an instant.

The man was still a little confused, but this didn't mean his reaction was slow. He moved his body, and wind elemental essence gathered around him. A cyclone appeared and Grey's attack was sent flying by the man's attack.

The man looked at Grey and didn't seem to recall where he had seen him. He had a sense of familiarity, he just didn't know where he saw him.

"Who are you, why are you attacking me?" The man asked. He had sensed Grey's cultivation stage from the attack just now and it was something he could deal with, hence his calm reaction.

"You've forgotten me, so soon?" Grey didn't attack, he stood and looked at the man's face.
