บท 194: Wind Sphere, Testing

William gritted his teeth as more Mana was added to the wind sphere. It swirled around violently for a few more seconds before bursting, causing tendrils of Wind Mana to spread throughout the room and dissipate harmlessly.

Damn, let's try again. 

William was trying to recreate a small sphere of Wind Mana that was located within the dial of the wristwatch. The only difference was, William wanted to create one that was twice the size and density of the original, requiring four times as much Mana, and incredible Mana Control.

I could upgrade the Wind Element to SS-Rank, but that would be expensive. If I'm going to put all the Elements on this belt, I need to learn how to do it with a lower rank. Master did it, so can I.
