"This isn't good. Even if I managed to keep going with a body like this with magic, I can't do much with low fuel," Billy said. "I need to get the hell out of here fast… shit, this is so annoying."
At that point in time, Billy could already climb the stairs while using Dash, so his speed increased considerably. Still, there was no sign of him reaching the top of the tower. He was considering amassing as much mana as possible and then exploding the whole thing…
That would be reckless since he had to find a way to return as well, and he would need a lot of mana for that. Regardless, things improved once again when Billy reconstructed his Spiritual Core.
"Now I just need to make it reach a crazy level and then accumulate a lot of mana," Billy thought. "Easier said than done, given that I will need tons of mana for both…"
In any case, Billy was starting to think that he was inside some sort of illusion spell. Since a while ago, the location of the staircase began to repeat itself. Moreover, he felt the same level of mana around all the whole floors…
"Remember… I need to learn Rage, Emotional Control, and my innate skill. Once I do that, I will manage to solve this mess…" Billy thought while he tried to call those feelings.
The only problem was that Billy couldn't remember things clearly since his magic senses in that body were different from the previous one. Regardless, learning Rage was relatively easy, and Billy used that to increase his movement speed once again. Once he reached a comfortable level, he tried to focus on Emotional Control.
Billy could recall the basics. With that skill, he had to send his mana to the target and then affect their brains. Billy focused on the Prefrontal Cortex. The term prefrontal cortex refers to the very front part of the brain located behind the forehead and above the eyes. It appears to play a critical role in the regulation of emotion and behavior by anticipating the consequences of our actions and inhibiting behaviors. The prefrontal cortex may play an important role in delayed gratification by maintaining emotions over time and organizing our behavior toward specific goals.
When he sent mana to the area of his own brain, Billy felt his own nervousness increasing, but that was because he was in a hurry… When he thought of calming down, the mana did exactly that, very slowly, because he didn't have much mana.
"Is that it? Is it that easy?" Billy frowned. "I thought that was supposed to be a super difficult skill that Uvish learned after facing some enemies that could do that… but the only difficulty was learning where to apply the mana. Well, my experience handling mana should have helped, but…"
In any case, Billy couldn't waste time thinking about that. He improved his physical strength by manipulating his thoughts and feelings a little in order not to tire his body too much since he also needed to gather and store energy with Chi.
Things stayed like that for a while until Billy managed to store enough energy in his body that surpassed his limits just by a little bit. It didn't take him a long time to surpass the limits of Chi, so his parameters were supposed to be increasing. Unfortunately, Billy failed at doing the same with mana.
"Well, I should be happy that I achieved this much so soon…" Billy thought. "I need to keep my focus since gathering stamina and health will make my body stronger, but I can't ignore Rage that will boost all my parameters up to one thousand percent at the max level."
Billy also had to learn Blood Manipulation and train it… once again. He had so many things to do and too little time, and he was getting impatient and losing his focus. Still, deep down, he knew that Uvish wouldn't do anything to his family and friends, and they were too strong to be ignored, after all.
Considering that his goal was to make sure that he would get stronger than any future invades, he also had to wait for a while before the barrier enveloped the whole world… Unfortunately, he could control all the mana of that world so that he could speed up that process quite a bit.
Billy sighed to calm down. He couldn't keep thinking about that, the thought that such an asshole was using his body and trying to fool his family and friends made him sick to the core, but that was something he had to endure for now. In any case, Billy's strength reached a point where he could cross half of the one hundred meters long staircases in a single jump. It was nowhere close to his level on the other body, but he was climbing a lot faster than before. With that in mind, he would have left the stratosphere in any normal world, but the air around him didn't get thin even once…
"This has to be an illusion… either that is the case, or I am locked in a teleportation trap," Billy thought. "I don't have time for this…"
Billy tried to absorb the mana of the walls and stairs, but he failed. Leaning back on his own innate skill was already difficult enough, and learning Lucyna's will be even harder. Still, considering that he learned Emotional Control, it shouldn't be hard. In any case, Billy recalled that he had to learn Sage's Wisdom by buffing his brain with mana. While he did that, he also used Emotional Control to increase his focus. After that, he began to climb the stairs a lot faster and without losing his focus.
As one would expect, it didn't take long for Billy to lose the notion of time… days, hours, minutes… he couldn't tell how much time had passed. Still, during that window of time, Billy realized one thing…
