After doing some tests, Billy frowned since that tactic wasn't turning into a skill. That would have made things a lot easier… In any case, he learned a few things during those tests. First of all, the mana didn't do anything even though the concentrations were high and close to his skin and clothes. Another thing that he learned was that he didn't have to keep too much focus when he wasn't sending his mana to his back. However, when he used his mana to do something else, the mana on his back would become hard to control, as if it was itching to be absorbed since Billy's mana pool wasn't full. It was almost looked like that had a will on its own, but it didn't seem harmful...
In any case, on the first day, Billy stored around fifty hundred points of mana, and he didn't notice anything weird when he woke up on the next day. However, his wives saw a small blue point on his back, and both of them could feel the mana inside it.
"It is just an experiment, don't think too much about it," Billy said.
"If you say so," Kate said.
"What are you trying this time?" Natalie asked.
"I will tell you why and the results once I confirm the safety of this," Billy replied.
Training something new that Billy couldn't understand completely yet was absolutely forbidden for his wives. Endangering them and the babies was something that he would avoid at any cost. Regardless, thanks to his spiritual core, Billy recovered the mana he used on the previous day even before he went to the dungeon. Hence, he kept channeling his mana to a single place. It was barely noticeable, but the blue point had gotten bigger, and there were no skills learned yet, even though the amount of mana had doubled. Once Billy returned to the dungeon, the amount of mana stored increased exponentially. Still, there were no signs of skills being learned or difficulty in keeping the mana in check. Aside from the time he was pouring more mana into the point, it was like trying to fill a cup filled with water with even more water while trying not to spill anything…
"Now that I removed the limits of my mana cap, I need to keep working on the tunnels and with my magic," Billy nodded to himself. "While lightning is pretty powerful and complicated to reproduce, it still is too weak and simple if compared to the powers that we received."
While his life was a pretty busy one, Billy was having a lot of fun waiting for his kids to be born and learning new things every day. He wondered if sailors felt that way when the age of exploring the oceans started… He also wondered if the human species will ever reach an age where they explore the cosmos. It was hard to imagine that they wouldn't commit the same mistakes as the explorers of the past, though.
After some point, it became almost impossible for Billy to pour more mana into that single spot. The amount of mana he had put there wasn't small by any means, but he still felt that just stopping there would be a waste… so he tried to create other reservoirs of mana. However, he quickly found a problem. Billy couldn't create the second two far away from the first. There was some weird reaction between them like the mana was recognized as a foreign object. So, Billy had to put those close… And that raised another problem. Like it was a magnet, the mana was being attracted to each other when Billy did the channeling, so he had to keep the same level of focus as before to prevent something weird from happening. He couldn't even imagine what would happen if all that mana went berserker. It might explode in his home…
"I suppose I need to keep training while using this much mana every day," Billy thought.
Thanks to all those experiments, that month passed in the blink of an eye, so Billy told Gustav that he would take a break from exploring his dungeon. After all, he didn't even try to clear it since he didn't make a map.
While spending more time at home to look after his wives, Billy also began to research alchemy. Since he didn't make much progress in that area by himself, he decided to buy some books from the people who had done some research about the subject. He had heard of the basics, but he didn't study deeply…
After a few weeks of research, Billy had an idea… What if he could turn the fruit of the Edish fruits into some small pills? That way, one would be able to take it despite the volume. Billy's first attempt at how to achieve that was by separating the liquid from the solid of the juice. Even if it was a concentrated version of something that had mana, Billy figured out that such a method would give him the basic powder that was filled with mana. After creating some tools for the separation for him for the experiments in his chemistry classes, Billy obtained a result… the 25 milliliters of juice turned into five grams of concentrated powder filled with mana. By using Telekinesis, Billy turned the powder into a small sphere and then added more of it and compressed it. He ended up creating a pill that restored one hundred points of mana that was smaller than the tip of his finger. It was a pit that he couldn't automate yet the method to compress the powder… And the only real problem was the fact that the pills were too sour. Still, Billy achieved his goal.
You have learned alchemy.
It increases the efficacy of digested sources of energy by three percent per level.
"I suppose this is more than fine for now…" Billy smirked. "Now I can finally relax and wait for their arrival."
