Voidlets

The four projects that he was working on went well as he worked on them. 

Project Skyfall involved him refining his heaven-bending along a single dimension. It took intricate precision to reach a level where he could redirect the vectors of force along a single direction. The amount of force he needed was actually little, this was a technique that tested his precision and accuracy. It was truly difficult.

Project Speed Prison was a little easier. Manipulating the drag coefficient to, be a variable that increased with speed was definitely not easy. He needed to alter the fabric of the atmosphere as a medium. This project required the most amount of constant trial and error. He constantly needed to test his prototype domains to ensure that he was in the right direction.
