The idea was really interesting, but it was easier said than done. In the first place, the surface of the human body wasn't uniform. It had too many undulations… While Billy was used to making Fierce Aura envelop his body, he couldn't control it once it was active, so he had to learn the skill from scratch. Still, Billy felt that he was on the right path, so he didn't want to give up and kept trying. Day in and day out, whenever he had some free time, he would try that. That was how he usually learned things, after all.
As for his wives and friends, they knew that he was up to something again since he was always meditating, or at least looked like he was. Billy felt more comfortable at controlling that mana while he was sitting in that position.
"This is stupidly difficult… damn," Billy thought after failing at doing that a single time for two weeks. "I am using tons of mana, and yet… What should I do?"
Billy stopped to think again about that ability… if it worked and could become a skill, then the more it levels up, the more powerful it will become. Considering its nature, more power also would be that the mana would flow faster around his body. So, perhaps he should try to do that as slowly as possible.
"Let's see… instead of making it spin around the surface of my body, I should make it spin like a sphere around me," Billy rubbed his chin thoughtfully. "This should be a good first step. After that, I just have to decrease its area until it covers my whole body."
Billy did exactly that, and as expected, things became a lot easier. While the mana around him had no real purpose, it still could block the wind to some extent. Billy probably learned some defensive spells following that logic, but for the time being, he wanted to focus on his current training.
Billy couldn't make the mana spin unless it had the shape of a perfect sphere, or at least the ground below him had to be even in order for the hole to be equal in all sizes. In any case, once the sphere got that shape, Billy managed to make it a spin. Very slowly, but it was spinning. Once that part of the training was complete, Billy decreased the size of the sphere. Eventually, it got close enough to touch Billy's body, and then all the energy dispersed.
"It is fine. Something like this was obvious," Billy nodded to himself. "I just have to make the mana get closer to my body, and then… Can I use Fierce Aura to help here?"
Would the mana be interrupted by another spell that is of the same nature? Billy tried to do the same while Fierce Aura was active, and he managed to control the mana better. It was only natural since the spell also boosted his magic. Still, instead of the mana of the second skill continuing to move after touching Fierce Aura, it just got absorbed. In the end, the answer won't be that simple.
Although it took him an entire month, Billy eventually succeeded with his training. The mental practice came in hand as well since it made him save mana and time. Actually, Billy succeeded after two weeks, but nothing happened. So, he kept practicing and increased the speed of the rotation of the mana, and when he could make it complete one lap around his body per second, he got what he wished.
Destructive Aura
A skill that makes the energy rotate around your body at high speeds to increase all of your parameters. Passively increases all of your parameters by five points per second.
Cost: 05 per mana per level and per second.
Billy achieved his goal, but he didn't think that the cost would be that high. However, it was only natural. Since it was five times more potent than Fierce Aura, then the cost was five times bigger as well. At higher levels, the bonuses will be insane, but only a few people would be able to keep the skill working for more than a few seconds. Moreover, learning would be extremely difficult. Even someone like Billy had a hard time with that.
"I suppose I should recover some mana in the dungeons and then use it to level up this skill," Billy thought while he was leaving the underground training arena.
Billy wanted to get ahead of his friends even more, but holding back the secret of the new skill would probably be a waste of time. There was no telling if even Sarah or Kate would learn that, and if they did, they would take months to learn how to control his mana like that.
"You spent the last few weeks doing nothing but practicing a new skill, and you are going to teach us this soon already?" Kate asked when the whole gang was reunited.
"Well, this time, I am not sure if either of you will be able to learn this," Billy said. "So, it is better to give you guys some time before you begin to work again."
Before giving them the details, Billy gave a demonstration. He invited everyone to the underground training arena and challenged Natalie and Alexander to a marathon. Rather than showing the difference in strength, it would be better if Billy showed the speed at some moments. When the marathon started, Billy used Destructive Aura for a second, and he suddenly became two times faster than the others. Unlike when he uses Flash, they could see Billy moving. In any case, they could reach that speed that was higher than even Billy's magic cart, but they would get wounded by the friction against the air. However, Billy was completely fine.
Eventually, they did an endurance and dexterity test as well, and Billy surpassed everyone by a large margin with that skill.
