"For us to properly cast a warp gate, we first have to create a spatial tear, create a spatial corridor to protect us, pinpoint a location in the real world, and finally creating a second spatial to exit the void."
"One step at a time, we shall look at tearing a hole in space. Like I said in the story, interacting with space is done in different frequencies. Meaning it is different for everyone." Professor Mack began demonstrating in front of the class.
"So you would want to focus your mana in the shape of a sharp object on a particular spot. Then you would want to steadily increase the flow of your mana in order to detect the right frequency."
The students watched as the area around the little-shaped triangle conjured by Professor Mack began producing spikes. When it got to its peak he slid his arm downward forming a cut in space, before drawing a circle around it causing it to widen.
"Now let's move to a conducive location." Professor Mack snapped his fingers warping them to a practice room..
"Before we start, there should be a great distance between each person and also between the spatial tear you are trying to construct." He warned them in case of an explosion while detecting the right frequency.
"Blake there is no need for you to participate in the exercise, so please stand aside and watch." Professor Mack said to Blake causing him to receive envious glares.
'Only if I could skip the class.' Blake helplessly sighed as he began watching the students try out dimensional magic.
As Professor Mack had demonstrated, the students had created small triangles and were very slowing, they were increasing the rate of mana flow into the triangle. After 20 minutes of going nonstop pumping in of mana, there were still no signs of sparks from any student.
10 minutes later students began dropping to the floor. For the top-ranking students, it took them 10 extra for them to also drop.
It wasn't only a case of mana exhaustion but also mental exhaustion. It required constant pumping of mana and precise control over their flow of mana and control over the conjured triangle on the same spot.
"At least none fainted." Professor Mack said as he watched the students panting and their clothes were drained in sweat.
'Why is it so difficult for them? Back when I was in the warrior realm I could only attempt it twice a day, but they only have a limit of 1 time a day, and they are champions? Also, why didn't you mention anything about the frequencies?" Blake through multiple questions at the system.
Having listened to Professor Mack's explanation of the process, Blake had found it to be almost the same thing the system had thought him, except for the frequency part.
[All your questions share one answer. Remember Dimensional magic is an attempt to replicate the spells of the space element and that makes things harder. The space pathway makes things easier by automatically tuning all your spells to the right frequency with only your thoughts.
In this case, they are spending more than 4 times the mana you spent back when you were in the warrior realm, just to locate the right frequency.] The system explained.
'This is actually a good way to train one's mana control. Too bad I wouldn't gain anything even if I took part in the exercise.' Blake shook his head in disappointment.
"Why… is it… so difficult?!!" Damon who rarely spoke in public couldn't help but ask in between breaths.
"Dimensional magic normally requires quite a lot of mana to cast spells, but the reason it is so difficult is that you are still trying to determine the frequency the spell operates. Once you get past this stage, it will be relatively easier." Professor Mack explained.
"Relatively easier?! Then how is Blake able to spam the spells without effort?" Vlad asked in an envious tone.
"Now, there are certain people that are naturally blessed with very high mana control that allows them to easily detect the required frequency. In Blake's case, he had had months of training to reach this stage." Professor Mack answered.
The truth was that by Blake being naturally blessed he meant having the space element. If it was some months ago he would have been wondering how Blake had mastered void shift to such a level on his own. This was because most young self-taught dimensional magic mages ended up dying.
"You all are tired and need to recover, this will be the end of the class and please remember not to try this without supervision" Professor Mack dismissed the class, and warped them back to the classroom. Immediately Blake stood up to leave the class, but that was when he heard someone speak into his ears.
"I will meet you at the corner." It was Professor Mack who was standing in front of the class, but his lips weren't even moving.
The class was still panting and were weak to get up, so Blake did as instructed and left the class. When he was out of sight a warp gate appeared right in front of him and he was teleported to Hoffenheim's office.
"It's been quite a while since we talked one on one." Hoffenheim said with a smile.
"Yeah, I have been very busy with school and adventurer life." Blake said with a helpless sigh. He felt kind of bad because Professor Hoffenheim had helped him a lot, but had forgotten about him for so long.
"I know the feeling of trying to remain at the top. It feels like there are tons of weights placed on your shoulders." Hoffenheim said. "Is there anything crazy that has happened so far?"
"Apart from what happened during the break it has just been nothing but school and not too crazy commissions." Blake replied.
"I would love to hear more about this adventure of yours. Please take a seat." He gestured for Blake to take a seat. "Liquor or coffee?"
