Attack?

"Hmph! Help from those old fellows. I'll still beat you up." Grey snorted coldly. 

The slight increase in the strength of the Summon had changed how things were going. Although he was annoyed by this, he knew he didn't have the time to argue. 

'Should I use another element? My time is very short now. I can feel my cores losing essence like a broken dam. The longer this takes, the more harm I do to myself.' 

He was caught in a dilemma. Showing another element would mean having to publicly use five elements. Having four elements was already very rare, five was over the charts rare, but it wasn't impossible. There were still people alive who had five elements. Once in a while, the rumors of a Multi Elementalist with five elements would spread across the Continent, it wasn't impossible for this to happen.
