Isekai Journey Of The Magic Archer

[Eon's POV: ]

"Imagine water…

The most basic unit: droplets.

They gather together higher up in the atmosphere, create clouds.

Due to temperature, the crystallised water drops gather together and rain down, or snow down in colder places.

Water Drops come down to earth and fill up the natural sources of water.

Water levels in rivers, lakes, even underground water sources increase and they flow from the higher ground to the lower ones."

He was drawing the entire water cycle on the other side of the blackboard right now.

"Rivers that originate from the mountains flow all the way down to the ground, then after connecting to multiple streams, it reaches the ocean, the largest water source on the planet."

He was using different colours to illustrate different phases of the cycle, and he was talented when it came to drawing these things.

They almost seemed realistic.

"Water in the oceans, under the constant heat of the sun, boils and evaporation takes place where the liquid water turns back into the original gaseous form, and lifts up into the sky."

He was done with the drawing, so he turned back to us, and pointed his thumb back towards the blackboard.

"Now… what happens to the gaseous water that goes back up?"

He paused for a moment and looked at how many hands were raised to answer that simple question and the new enthusiasm they had placed a smirk on his face.

"It turns back into clouds, yes. I know not all of you are dumb enough to not understand even that much."

It was a taunt to those who did not understand why he was suddenly talking about water and this whole thing when we were talking about the concentration of energies just a moment ago.

'The topic shifted from Aura, Mana, to energies, and then to water so quickly that even some of the good students were confused right now.'

But it did not mean they did not understand what was going on right now.

He was explaining everything so well that even if they were half asleep right now, they would still at least understand the meaning of these things.

Not that he would let anyone sleep in his class… he absolutely hated it when someone did something that was not appropriate to the classroom environment.

"Now… look here."

The topic had shifted from energy particles to the common water cycle that we had already learned in the earlier Understanding nature classes.

How water transformed from one form to another was common knowledge among the students, so this was going to be much easier for them to understand.

"The smallest water particles= the energy particles.

The clouds are, as some of you might have already guessed, the Mana environment all around us.

When it rains- or in other words- when it condenses into a different denser, Mana becomes either Aura, or Aether, or a unique energy that many of you might have already heard about, the Force.

When it reaches the surface and becomes part of a greater resource area- the Mana or in this case, the spirit Mana or the Arcana becomes thinner, less dense, and takes on the form of great quantity at the cost of its 'potency'."

There.

He finally used the right word at the end.

'Now it will get interesting.'

Rein was getting more focused on this explanation even though she knew all about this and much more, but, from what I can tell, she was taking this as a revision.

'She was referring to this whole example and was mentally applying all of this to Shadow energy.'

She wanted that power and she was going to get it one day, but that day wasn't going to arrive anytime soon.

'And since Wali also advised her to not worry about such things, she didn't have it on her mind until now.'

But now that she was hearing his explanation that was the ground basics for many of the things that she uses on daily bases, she was having a surge of inspiration.

And, since she was even taking notes of this whole thing, it was obvious she was enjoying herself and whatever was going on right now.

"As the potency of energy particles, or to make the understanding simple, as the potency of Mana changes, the form of energy that we know as Mana changes into something unique.

Just like how Aura degrades and becomes Mana, Mana could be condensed into a higher form of energy, but doing it artificially would be the same as producing the fuel that Sun uses.

It's a natural process that happens naturally.

One form of energy transfers into the other, it condenses or degenerates from the original, mixes up with the other Natural factors, and gives rise to the unique powers that are later used in various forms.

The potency of Mana in the given energy decides the nature of the energy, and the elements that connect with Mana to create these unique energies decide the characteristics of these energies."

He was a vampire and the unique energy they could use was the Blood that most living beings with physical bodies possess.

So, as he explained those things, he demonstrated it with all the energies that he could control as well.

-Oooooooooong.

"One of the most important things to know about Mana is that it is in the pure Centre of everything."

He was a Pure Magic master so he used Mana and created orbs of elements that he could control, and including them, he created orbs of Blood energy, an orb of Aura-Mana on his palm, a few smaller orbs of spirit Mana with the use of his contracted spirits-there were three of the lowest level ones present right now- and including that, he also conjured his Origin energy.

"The Origin energy that one receives directly from their origins are the positive extme of this line, the Divine energy of the higher beings falls near there somewhere as well, while though there are speculations that an energy complete opposite of origin energy exists, just like how demonic energy and shadow energy exists on the negative side, it has yet not been found."

Most of the things that he had said until now were things that I had learned before in my (All energy utilisation) class so I wasn't that surprised by it, not that I was surprised back when the old teacher taught it either, but most of the class was in a complete daze right now.

'It was obviously difficult to fathom how there were positive and negative side of these energies that not many people usually pays attention to, and, it was even more difficult to see Mana as something that could be taken as a central point in this picture.'

Not all of the individuals in this classroom could use Mana itself since having a Mana nucleus was a rare thing.

There weren't many mages in this world since the magic itself was no simple thing and that was more of the reason people trained their bodies.

Awakening Aura wasn't any simpler than awakening an energy nucleus, but not everyone could awaken an energy nucleus, but there are high chances that if someone actually gave everything they had and dedicated their very soul to the task that they might awaken the stronger force than Mana known as Aura.

'Even in this class, most of the individuals were weapon users, a few of them were mages, some of them were children interested in the artistic fields, while those who wanted to walk the path of creation were the lowest.'

And still, statistically, there was a chance any of them could awaken a unique energy that would let them do special things that no normal human would be capable of.

"Potency. Remember that word."

There were artists that did not have an origin skill from birth but they obtained it along the way in their lifetime.

There are many craftsmen that have never trained to wield any weapon ever in their lives and they still could use Aura.

There are individuals who awaken unique powers that not even the special individuals could through natural circumstances, or just because they were meant to, it was certainly a common thing.

'There were many cases like Chry in this world, individuals that have skills so powerful that their bodies act on their own to make it so the possessors of those skills itself don't find it until they are ready for it.'

People who always possessed a certain power but could not use it or even knew about it until a certain point was not anything new, there have been many cases of fortunate or divine awakenings throughout history of this world.

So, ultimately, there was always a chance a normal human of this world could become a supernatural entity overnight.

-Trrring~! Tring~. Tring.

"That would be all for today. Let us start the sixth unit from the next class… remember what you learned today. It will be very helpful going forward not just in this class, but throughout your life.

The revision is today's homework. And don't ask me anything about today's class ever during any of the classes.

I'll reply if I get a personal message only if I find it appealing. Otherwise, come directly to my office."

-Tap. Tap. Tap.

Tapping the table three times as he always does before leaving, and wiping off the blackboard like every teacher should, he picked his books.

"See you tomorrow."

And then after that small goodbye, he started floating once again and floated out of the classroom, leaving us poor students to our own devices.

"Jerk."

She wanted to write something before he wiped it off, but since he didn't give any warning this time, she couldn't even ask him to wait.

"Take mine later, dummy."

"I'm not a dummy. You are the dummy! Hump!"

She was angry at him earlier, but he grew up on her. Or, it was better to say what he taught today grew up on her.

'She was still in that flow state… so, even though she wanted to continue cursing at him, she threw that all on one side and continued writing.'

She was working right now… a rare cute side that I didn't want to disturb.
