"It was a living thing with consciousness' solidified energy~"

Ms. [Dianne] said nonchalantly.

One of her students raised his hand.

"Yes, what is it?"

"If that was true, why isn't it discovered during the First Demon War or some minor revolutions inside the kingdom?"

"That's true. But think of it, how many died during the First Demon War?"

She asked that student again.

"It... wasn't counted.."

"Yes that's right. Because First Demon War was just a title given to the battle between the First Hero and the First Demon King. Other than that, there are no major casualties that make that event a memorial one. That's why Second Demon War was much commemorated than the First."

"How about the revolution?"

"That's also a no-go. [Etrium] ore was found inside the corpse of those who died during the Second Demon War. Since the kingdom didn't have the money or manpower during that time to burn the corpses, those corpses left untouched until one year later, which is the start of reconstruction."

She continued.

"After the kingdom and [Hachn] Academy learned its origin, the kingdom proposed to create burial grounds than to cremate the remains of people who dies within the kingdom. But think of it, who in the world wants to have their own loved ones being excavated as a source of energy? Even though it is for the benefit of the whole kingdom, people won't like that idea."

True. Even I wouldn't like it.

"[Etrium] excavation also sparked revolts throughout the kingdom. Most notable among them was [Felminhaut] saying that if we use that ore as source of energy, it makes its dead owner or the source unable to reincarnate."

All of us were shocked. Even us, might join that rebel group if that information is true.

"Is it true...?"

[Eleonor] asked her with a worried expression.

"Hahaha~ don't make that face. It is a sophistry. Before they used [Etrium] as a source of energy, all of the researchers examined it thoroughly. The 2nd Hero [Lewis] himself proclaims that it isn't a harmful ore. Since the [Hero] and the [Demon King] are people who were born with their past memories intact, they are the perfect example of masters of the mysteries behind body, soul, and energy."

"He explained that when people die, their soul will detach from their body within a certain time, leaving the body and energy behind. When the dead body experienced [Rigor Mortis] or stiffening of the body, energy within the body also stiffens, making it solid. After a long period of time, the body rots, leaving the solidified energy behind."

She says that while her hip is swaying and her hands are on her cheeks. It looks like she adores the previous hero very much, huh.

"Ah, Sir Hero~ The one who reached [Nexus], [Urm] and [Jarg]~ Please teach me all of your secrets~!"

Well, her passion towards the hero was off the mark.

"Other details about that research was elemental attributes of [Etrium], difference in concentration level between human and demon body, and others. Now in our goal in this whole semester, is for you to learn how to create solidified [Etrium] by using your own energies. Like this!"

She opens her right hand with her palm facing the ceiling. Light-like particles comes out of her body. After a few minutes, a green refined stone pops out of thin air.

"This is just an example. But you could shape it to something convenient."

Then she placed her left hand on the top of the stone and her right hand. After doing that, some light particles covered the green stone. It rotates continuously until the features of the finished product appears. In place of the green stone, 6 green bullets emerged. This are bullets that could be used for a Pistol model Gun's.

"Convenient right~? Is I want to say, but it really exhaust most of my energy."

Her face lost some color. It must be really hard to do.

"So I, as your teacher, advises you not to do this unless its emergency, like when you're on the field and there is insufficient supply of ammo, and other circumstances."

"What I created was a green [Etrium]. Green color stands for the Air element. Each person has different elements residing within their body. The name of the known element within our world were: [Fire], [Earth], [Water], [Air], and [Void]. Some might have multiple elements, but most of the time there is only one dominant element for each person. There are some cases of two elements, but there is only 2 in whole research history was recorded to have all 5 elements inside of them. If you didn't catch that, I'll tell you who: The Hero [Lewis] and the Demon King [Pollux]."

One student raised his hand.

"Yes?"

"Ms. [Dianne] if that's the case, then why all [Etrium] being manufactured by the kingdom were white in color, not in other colors that correspond each element?"

"Those were artificially-created [Etrium] ores. By mixing all elements of [Etrium], they created that [Etrium]. How to make it.... is a secret. He he~! You'll learn that when you become a Master Magicsmith~"

"Stingy!"

All of us exclaimed.

"Well, that's the rule. If it was publicized, it might be used as weapons for uprisings against the kingdom."

All of us thought that her argument is valid.

"By the way,those parts rejected during the process becomes [Blazerock], [Aquarock], [Prune], and [Freon]."

"Oh, by the way, that levitator is made of [Prune], also known as gravity rock. It looks like an ordinary rock until you infuse it with energy. When that happens, that's the only time when it would show its true nature, a floating rock."

"[Aquarock] is also a good source of pure water, since it's made of pure energy transformed into a solid water. Unlike [Ice], which is a sub-element of water, it doesn't have that cold feeling when you touch it. It remains solid until infused with energy."

"[Freon] is the second hardest stone known in existence, after [Adamantine]. It replaced [Mithril] and [Orichalcum] when it was discovered."

"Going back to the topic, before I teach you how to create you own [Etrium] stones, please make a line first row."

All of us wondered as she ordered us to make a line.

As she puts back the gigantic book at her pocket, she holds the crystal ball magical tool.

"This item here is the "Energy Measurement". It shows what is the capacity of energy of the person who will hold it and the element of that person. My limit is 7,000 Energy and my element is [Air]. As you train your body, your energy also rises. The first one, please hold this."

Then she gives the ball to the first person in line.

"[Lyra Aker], Limit: 500 , Element: Water."

It shows a screen being suspended in the air. It must be the work of the principal.

After the next row ends their measurement, The third row falls in line. [Eleonor] was the first one to hold the ball.

"[Eleonor Vega], Limit:  15,000 Element: [Earth], [Fire], [Water], [Air]."

"!?"

All of us were shocked. The average limit of the class was 1,250 but she set a record beyond expectations of the whole class.

Ms. [Dianne], who was supervising the class, shouted out of her shock because of [Eleonor]'s result.

"A rare genius! You may not be classified as the [Demon King] or the [Hero] because you lack the [Void] element, but you are beyond the league of geniuses! A Genius among Geniuses!

[Eleonor] looks like she didn't mind the flattery, looks at me. As our eyes meet, she smiles and says:

"Its your turn [Yves]."

"O-okay."

As she gives me the ball, all of my classmate's stares are pointing towards me. For me, their faces looks like those of beast before devouring their prey. Shaking, I took the ball from [Eleonor], holding it by using both my hands.

"[Yves Altair], Limit: 100 Element: [Earth], [Fire], [Water], [Air], [Void]."
