"My innate ability is the 'word of power' and it does whatever I say and feel like, thus, I shall be called 'Will'." So, using the 'word of power' which was the story-mode Min Hong's life essence, he spoke into this empty void.
The moment his statement was made, the void shattered and a mystical containment was formed, the rampaging black cloud was sucked and imprisoned within it. Then Min Hong spoke once more and said; "For you were borne of void, you shall be called; Space."
But in response to being contained and restrained the gas cloud responded with increasing rampage. Then Min Hong [Will] began to device a way to stop Chaos, but due to the rate at which Chaos power rose, he needed to speed up his thinking speed.
So, he used the 'words of power' and spoke into the void once again, and the reaction and rampaging of Chaos was greatly slowed significantly, while that of Min Hong was boosted.
