Rui had to admit, this was an unfortunate sequence of events for Kane. Not only had his initial ambush failed, but the man also just happened to have a gigantic attack that could fill up the entirety of the colosseum.
Because it covered all available battle areas, Kane could not avoid it with speed. Getting his by such an attack was inevitable. However, Kane had greatly minimized how much damage he took by moving to the very edge to withstand the impact.
However, he had to admit, he was impressed. Although Kane was extremely fragile as a Martial Artist, hurting him by simply attacking everywhere despite the dispersed and diluted impact was quite impressive. Rui suspected that the technique he used was probably grade ten, or grade nine at least. He could not imagine such a technique being mass viable. It was a testament to his power and mastery over the winds to be able to unleash such an attack.
