Billy divided his actions into steps. He couldn't use Acceleration Manipulation, and learning it would take a while, and it will consume a lot of mana. So, he decided to use Blood Manipulation. That one had been a lot easier to learn. Billy just had to put some mana in some parts of his heart, and then it would make the blood move faster… it also would make his heart beat faster, but one can't have their cake and eat it at the same time.
After that, it was time for the second step. Improving Billy's brain capacity with mana and blood. Billy managed to think a lot and discover the tricks behind techniques like elemental creation. Still, his goal was to regain his innate skill, which has been a bit harder… Still, he couldn't rush it. He had to keep his progress steady and slowly increase its speed. That way, the chances of failure will decrease... or so he had assumed.
