Strange Technique

The two old men looked at each other and couldn't help but let out a sigh of relief. If this was what the lady wanted, then they wouldn't need to worry about losing anything from the mansion since Clara would easily defeat Grey. 

They suddenly concluded that the lady was probably trying to train Grey, and since they weren't from here, she didn't know where to get opponents on his stage. And she might be a little overconfident in him. 

The old man in blue stepped forward, "Since they're going to spar, why don't we give them a good platform?"

"You can do as you please," The lady waved. 

The old man nodded, before waving his hand which caused an ice platform to rise from the ground with Grey and Clara standing in the middle. Around the ice platform was a pool of water that ran around its edge.
