The Thunder King seemed to have a reasonable explanation for what was occuring with the barrier made of iron sand. Upon hearing it, Chiyo nodded her agreement, what she understood of the information scientifically meant that she could understand at least the simpler parts of said explanation and it all seemed okay with her. She couldn't imagine having such a self-sustaining barrier at her own disposal and felt inclined to try and make one of her own at some point. She remembered having a trick that would be a suitable base for such a thing. But that was not what was important right now. The chain reaction and explosion she'd set off while thinking had apparently caused an interesting and different reaction from the Thunder King's area of influence. Her eyes were darting around as the iron sand began to move, and she soon found herself moving on impulse out of the way of the wall of coming spikes. Surprisingly enough her reaction speed and body placement were so precise that she was missed by all of the spikes, simply by pushing her body away from the area at top speed, only to have the final spike stop right before her nose as she stopped again. "Holy fuck, that was close and fun." she said but such a statement was only followed by the laughter of the Storm Queen, she had to appreciate the abilities of the Thunder King and held a great deal of respect for him. Beyond that, it was fun playing with him in the manner they were currently doing so. "So, that is one hell of a defense ya' got there... luckily enough I don't think of you as a meal or this would be really hard work." she commented. But her movements in the moment that she'd escaped pushed her limits quite a bit, her own reaction times were far beyond the norm, and that reaction seemed to exceed even her own expectations. "How long can you keep that up?" she asked curiously enough. She wondered if the barrier itself or its maneuvering were hard for the Thunder King.
