Grey looked at the swords that were used to trap him, he couldn't help but marvel at the battle techniques of old people. Even in the Gnome world, all fighters are the same, once they're facing any challenges, they will look for ways to overcome it.
At the moment, the Old man knows that he's not as fast as Grey, and after seeing the explosiveness of Grey's close range attacks, he was doing everything in jail power to ensure that Grey doesn't come close to him.
Grey didn't mind this, he just didn't think the Old man would have ways to trap him. Of course, he still hasn't made use of his space element, and he was keeping that for a surprise attack if it proves too difficult to escape from this hexagon.
