4 days later he finally broke free from his trance.
Over the past few days, he did nothing but read the words of the book and see the effect it had on the ambient mana. He tried to look for demonstrations of the skill online, but it was such a fundamental skill that nothing he found was very educational. Why would someone have an in depth analysis of such a common skill? If you want to know more about it, then practice using it a bit.
After 4 days of not even eating or sleeping, he was finally ready to attempt to recreate the skill. But before he could, his nose was assaulted by a foul stench accompanied by a growl that sounded like that of a caged beast.
Sitting still for 4 days in a hot apartment isn't the recipe for smelling anywhere close to good, and as an awakened person he had to eat more than a normal person.
After a quick shower and eating some leftovers, he looked outside and saw that it was the middle of the night and he was rather tired. With his high vitality he could stay awake for weeks, but he like everybody else would get tired after a few days.
"I want to be at peak performance when I do this. This is a spatial skill after all, if I f*ck it up then a lot will go wrong." He didn't know much about skills but if there was one thing he did know, it was that when it comes to pure destruction, nothing could compare to skills relating to space or gravity.
As such, he wanted to be at his best with his body, mind and soul when doing this, there was no telling what could go wrong if he messed up because he dozed off a bit.
Quickly falling asleep the dark room was once again illuminated by his mana as he was in his most calm state. As he now knew 'Mana sense' if he was awake to see this he would be shocked to see just how much his body was absorbing. But, he could never be this calm while awake so he might never see it for himself.
On the morning of day 6 of his one week vacation, he was woken up by the noise of the street not too far away. His apartment building was right next to the street so the noise of cars, people and stray animals always woke him up early. Like a strange and even more annoying version of an alarm clock, if people still used those.
After washing his face, he cooked himself breakfast and did some stretches. One of his previous instructors told him to do this daily to maintain his flexibility, he didn't really understand what that meant but it didn't hurt to do it once in a while.
"I need to go get some weights as well, or a gym membership." Now that he wasn't going to be trained physically, it was up to him to continue to increase his stats. He didn't know what magic training entailed, but he didn't believe that he would be running for miles and lifting weights like he had done the month prior.
"Let's get started, shall we?" Not wanting to waste any more time, he cleared a space in the middle of his apartment to sit down.
He opened the book and started to pour his mana into it slowly. He wasn't trying to learn it as a skill so he didn't put in the minimum required, but for him to mimic its effect, he needed to activate it slightly.
"I hope I have enough mana for this." One of the main reasons, besides just forgetting about it, for not learning [Inventory] sooner was because he didn't know if his capacity was enough to overcharge it. He didn't know if he learned a skill normally, if he could still use his method later and something told him that he would want to be prepared to overcharge [Inventory].
"Maybe not for the same reason but I'm still glad that I waited." Focusing on the fluctuations brought by the book, he extended his mana out from his body and started mimicking.
As he slowly increased the amount of mana he poured into it, different parts of the book activated. Unlike other skills all of the text in the [Inventory] book was blue, which meant that it needed much more mana to activate the words and the fluctuations that he had to mimic were much more complex. It was even more complicated by the fact that he didn't learn the skill so he was missing the familiar feeling he relied on for his other skills, mana sense was more detailed but he relied on that feeling to have a bench mark.
At first, while complex he could still follow the flow of mana easily, but after a while it got to the point that even he needed to put all of his focus into it. As more and more of the book got activated, he was focusing so much that he lost perception of the things going on around him.
About half way through, as the difficulty spiked, almost all of his mana was being mobilized. If he was fully conscious then he wouldn't have gone this far as he had never used mana at this scale before.
With just the sheer volume of mana being moved around, many anomalies happen around him. A wind swept around his room lifting anything not bolted down, forming a tornado around him. Because of the wind pressure his windows blew out and his door exploded off of its hinges. With the massive surge of energy around him, he was floating 3 feet off the ground, legs still crossed.
If someone entered his room and managed to not get swept up, then what they would see is a tornado of random household objects. But what a mage would be much, much more concerned. Mana only moved like this when a gate was being formed, which would mean that it would have to be quickly cleared or a catastrophe was going to befall this part of the city.
But if one managed to acquire the 'Mana sense' ability, then they would be too shocked to even move. In the center of this mana tornado was the body of a teenage boy, floating as if not affected by the winds around him, along with what seemed to be a skill book. His skin was glowing brightly with strange looking tattoos and his eyes were glowing blue.
The mana in the tornado was being drawn into his body, but none of that would leave them too shocked to move. In front of the floating boy, was a pitch black crack. Space itself was being torn open by whatever the boy was doing and the crack was getting larger and larger by the second.
