In the past nine months, Project Skyfall and Speed Prison had made optimistic progress considering the fraction of time that he was limited to working on them. For Project Speed Prison, he had discovered the manner of heaven bending needed to alter the drag force and drag coefficient of the atmosphere within his domain.
This meant that he had already found the solution to the biggest problem. Now, all he had to do was master applying it within a large area and embed the heaven bending into his muscle memory.
This, unfortunately, was raw and hard, repetitive training that could not be skipped. He was going to have to put in effort in order to declare the project complete and a success. One of the things that he wasn't the most fond of was the fact that there was little to nothing he could do to speed it up, but there always were elements that could not be accelerated.
