One punch

"It is impressive I could say. But as I told you, you can't defeat me using water."

As soon as the man said that, soil rose to that air and covered the two of them. 

"Ugh!"

Kain stopped moving, closing his eyes and lowering his head. The soli has entered his eyes and nose, making his eyes sore and his nose itchy.

"A-Acho!"

'What the hell!'

He thought he was going to choke for a moment. He moved his feet to get away, but his feet were stuck in something and he couldn't do so.

He opened one eye with difficulty and looked down. His feet were covered with solid mud.

Kain stared at his enemy who was standing still amidst the swirling soil. 

He could see his water wall that was now a mud wall, and his spear that was now as solid as a rock.

He couldn't attack the man, nor could he move. His surroundings were completely covered by the swirling soil so he couldn't even see the others.
