Billy couldn't use Appraisal, but he could tell that the walls were at a high level. So, he tried to use his power to move, take the mana from the walls and turn it into an experience for himself. He failed…
"You think that you can use your pathetic powers on our Creation and obtain results?"
"It looks like a few years of success and victories against weak beings got to your head."
"We have been alive for thousands of years, and it would be an embarrassment for us. If someone powerless like you could do anything against it."
"Shut up. No one asked you anything," Billy said.
Billy knew that it wouldn't be easy, but he had to test it Anyway. Regardless, he just had to keep improving his powers, and eventually, his magic would be powerful enough to affect the whole tower. Still, Billy felt that things would be more effective if he could also learn Lucyna's powers.
"I suppose now I need to find a way to pass the experience and knowledge of Rage to other skills or to myself," Billy rubbed his chin thoughtfully. "This will be hard…"
It would be hard to the point that Billy wondered if it was better to keep focusing on increasing his magic and then try to use Personal Domain again. The technique could drain some mana from the environment, but it would need to become a lot stronger to work on the tower…
Billy used his head with focus to think of the most efficient method. In the end, leveling up his core and then using a shit ton of mana to make his body ethereal would be a better option since it would increase his magic and thus make his innate skill more powerful. Apparently, when he used it for the first time, he got quite close to the life spirit power level, but he would need a lot more for his powers to reach the level of those three.
Things might work better if he captured them and used their powers in his favor, but Billy didn't want to become like Uvish, who would do anything for victory. Still, he couldn't discard that possibility, and it would depend on how they will act from that point onward.
"I also have to improve the other technique… This way, I will manage to surprise that asshole," Billy thought.
While he was thinking about his next steps, Billy focused on gathering energy. Keeping his magic at high levels will also help him learn difficult spells, so perhaps that was the best course of action.
Things were proceeding well, but Billy felt that he would need at least a year to recover his old strength. He also needed to increase his speed when it came to magic training… perhaps he should focus on learning Time Skip, even though Billy had no idea how to do that since he had never learned the skill before. Still, it worked well on Icarus' hands.
"I barely scratched the surface when it comes to time magic with Acceleration Manipulation, but I guess there is no better time than now to try that…" Billy thought. "Fuck, why there are so many things to do now… that piece of shit will pay as well for taking all my progress from me. It will be refreshing once I kick his ass and do the same."
In the end, Billy focused on gathering energy with Chi and using the other methods to increase his magic as much as possible. At some point, that progress speed slowed, so Billy began to wonder how he could make himself level up and then use the extra parameters to increase his magic. Usually, the parameters would split evenly. Or, they would fall more on the side that the user uses more… Billy didn't do anything physical training now, so it probably would fall on magic.
It didn't take long for Billy to convince that theory when he used some mana and made his soul absorb it. At the same time, he felt his magic getting stronger… which was good. Things were proceeding better and better over time.
Around the time Billy finally managed to create a thin layer of his personal domain, he decided to test Exp Master. Unfortunately, he didn't get any results, he also tried other innate skills. Unfortunately, he didn't get much result… Still, Billy probably could create a core and drain mana from the environment and use it. However, he created a small one, and it suddenly cracked and exploded.
"What the hell…" Billy said.
Billy was certain that he didn't make any mistake, so he couldn't understand why that happened. Still, when he tried again, he used Magic Eyes and saw what happened… The mana of the place suddenly overloaded the crystal.
"It must have been them… They aren't getting in the way exactly. Still, they won't tolerate the Creation of anything that opposes their authority," Billy thought.
It was clear that the spirits did that… Billy wondered when they would try to get on his way, but they had been pretty lenient, and they took their time to do anything. It seemed that they would allow Billy to do pretty much everything… Regardless, to be able to do what he wanted completely, Billy would need to increase the length of his Personal Domain.
"Let's focus on that since my mana recovery increased thanks to it," Billy thought. "I will need some cores to improve my progress, and it is a lot more feasible than learning time magic.
Billy's progress was all over the place, "even though it couldn't be compared to before. Naturally, since his knowledge and experience helped him more than a little bit. Still, unfortunately, things wouldn't go the way he wanted forever…
All of a sudden, the air inside the tower began to change, and Billy felt like he was inside a cage alongside a dangerous beast. At the same time, Billy had a hard time breathing, and he felt like countless needles were piercing his skin. It seemed that letting Billy progress beyond that point wasn't something that the spirits wanted….
