Isekai Journey Of The Magic Archer

"Don't even think about it. The bodies of demonic beings must be handed to either the temple or the academy for research.

Just be happy that you even got the chance to see these cool things.

Ah... you can take some materials if you want. I give you thirty seconds. Go start."

Both of us knew he was serious and what he said was also true. There was nothing we could do to the intact bodies of the demonic creatures, anyway.

Though I would never let go of the chance to collect the materials that could be helpful in some unknown scenario.

'He's really smart to know what I wanted, too. Really, a bastard...'

[Quick steps]

(: Speed enhancement), (: Light protection).

He was the headmaster and the words he spoke might sound normal, but from how much I knew him, he was dead serious this time.

Just the fact that we were here and there was a demon noble's corpse laying before us was something unbelievable.

One would die or go crazy just from being in this presence of demonic energy, after all.

Though I could circulate this demonic energy and still survive for a long time thanks to my special physique, it was still harmful.

If mom were to know of the current situation, she would most definitely cut off all the trades with the academy, causing this bastard headmaster to suffer.

It was a dangerous place and a potent poison to any being of nature, so cleansing it as soon as possible was a must.

I understood that much, so I didn't hold back this time.

I didn't know when else I will have a chance to collect the demonic materials so I went all out.

-Swish!

First, I appeared before the bisected demon corpse that was covered by a lake of black blood that was creating a black fog and collected some of this blood from the ground, from the body, and from the black heart-like crystal that I could see, and stored it in a special purple vial.

I knew he was smirking again at this scene while Rein was collecting materials from the demonic beasts and the demonkins.

She was a witch. Just like the wizards, their physical bodies were also different and didn't get affected by the demonic energy to as severe an extent as the normal or even strong humans.

She understood this would be helpful and how important it was for me, so she was helping me... good girl.

Anyway, after blood, I jumped in the air using my special shoe enchantments and collected some samples of its bone powder, some samples of the clothing materials he was wearing, and lastly samples of his demonic energy.

The work was easy with the thin layer of light elemental Solnova spell around my body. And after storing the energy sample in a unique white vial, I backed off.

There were still ten seconds left so, I closed my eyes and looked at my 'spell storage'.

There was one special, very difficult, and unique spell that will shock the headmaster among the nearly countless spells that I had already scripted.

I didn't even have fifteen of them, the encoding taking more than a few months for just one in this outside world. But there was a freshly dead demon before us. So it was worth it.

[[ *You will be using it for the first time in the outside lands. It will be different from our previous home, so be careful. It might feel different.* ]]

Even Lucy was worried about this, and I knew it would be difficult. But it was worth it.

'I will be fine.'

"Haaa..."

I closed my eyes, walked into the floor of books in my mind tower, reached the place where the spell I wanted was stored, took out the book of the spell, and ripped one page from it...

"(: Harvest)."

A golden magic circle appeared before my hands.

-Swiiiiiiiiiiiiiiiiiish!

A black magic circle that looked like a void, an empty space, or a black hole appeared before the golden one and started sucking all kinds of energies in.

It was a two-circle spell, high-level magic that shouldn't be possible with my current (tier-3) mage status. But I was using almost all the Solnova I had.

The demonic energy polluting the air, the natural Mana and other ones present in the air, and most importantly, the soul energy of the dead demon that was still present there.

Every energy was sucked in by the black magic circle while it all gathered behind it.

A reaction was happening in the middle of golden and black magic circles, and something was materializing there.

A soul would only stay in the atmosphere for a minute or half after the death of the physical body and then become one with nature, so I only had a short time.

-Swiiiiiiiiiiiiiish!

The black magic circle continued sucking while Rein had finished her work and was looking at me blankly.

The headmaster had a rare astonished reaction while looking at one of my original masterpieces. I was also proud of this one.

But the burden that this one spell put on my body was far more than seeing three status windows of these demon-like beings.

The speed at which the Solnova was being used was more than I had thought, but the small thing appearing between two magic circles was worth it.

"Ahem!"

I coughed up some blood. I couldn't hold back this time. But it was better holding it in and risking the aftermath.

"Eon...!"

Rein was worried, but she saw the smile on my face as well as the absurd smirk on the headmaster's face, so she understood it was alright.

-Swiiiiiish.

The black magic circle became blurry after just a few moments, while the golden one became brighter. And then...

-Ooooooooooong!

The black magic circle disappeared while a light shot out from the golden one into the transparent crystal that had materialized there.

"You damn bastard..." the headmaster cussed and appeared behind me and caught me just when I was almost falling down.

"What are you?" He asked with a smile that was warm, happy, and shocked at the same time.

I was in his arm and though this time my mind was better than a while back when I looked at the statue window of the demon, my body had close to no energy.

I used almost all the Solnova as well as Mana in the process... I was still weak to use my own scripted spells.

Well, I was fine enough to take out a potion from my white crack and drink it.

So, with the headmaster's support, I opened the white crack with much difficulty, took out a red potion, and drank it as Rein also appeared to support me.

-Smack!

Of course, she first hit my back with actual strength, which hurt like hell in this difficult moment.

"You will be punished when we get back."

Maybe she was crying. Her voice certainly told so.

"Aye aye, ma'am. But after our lunch. I'm super hungry after this thing."

Red potions that grandma made were my lifesavers. Without them, I don't even know what would have happened to me.

"Haaa..."

I stood up after some laying in her lap and then looked at the small crystal in the headmaster's hand.

He was looking at the transparent crystal with strange black particles swirling inside it.

"What do you call this?" he asked as he observed the crystal with his special rainbow-like eyes.

He was the strongest archmage, had more than one world authority, and one of them was related to seeing things.

He was able to see through me. Something a demon and even the king-ranked knights failed to do.

Knowing what this crystal was and how it can be used was naturally easy for him, but the name was a totally personal thing.

"I call it <Core crystal>. Cool right?"

Just like how any common energy beast materializes an energy core inside their bodies after death, the crystal was something like that one core that contained the base soul energy and other natural energy that the target had.

"Gluttony right? You recreated functions of gluttony. But instead of directly ingesting the energies, you turn them into a crystallized form.

Fascinating..."

He really was shocked by this. Something to really be proud of.

"Yes. The black magic circle is based on the pinnacle skill [Gluttony] while the golden one is based on the pinnacle skill [Harmony].

It's nowhere near those amazing skills though, and it's also still not a perfect version of the spell.

I still have a long way to go..."

It was true. I still had many things to learn and achieve.

"Hahaha. Right. You have surprised me so many times that I forget that you are still young. Still... how do you even know so much about the greatest skills of nature to be able to create spells based on them?"

He was curious, and the answer to that question was actually very simple.

"I-"

"He must have read it in some books. Right, darling?"

"Yes..."

Maybe the answer was so simple that Rein couldn't help but answer on my behalf.

It wasn't wrong, though. Most of my knowledge came from books, my own experiences, and things that my master taught me.

This particular spell was something that I created on my own with the things that I learned from her as well as from the books.

"Hmm... can you tell me which book? Or better, can you teach me this spell yourself when the time comes? I assure you the compensation will be good enough to please you."

"...what?!"

Rein shouted at his words, but I understood that actual desire to learn from me.

"It would be my pleasure. Though we could only do that after we are in the academy. That's ok, right?"

I could just produce some copies of the books that I read for him, but that wouldn't be as effective.

He was asking me to teach him my own personal spell.

It was my work and something that could shake the whole world; we were talking about artificially creating the natural cores from the environmental energies after all.

It was also something that only a few with the power to use special energy better than Mana or Aura could use.

He was the greatest mage, and he just came across something that he didn't know about.

This was a piece of new knowledge for him. Something that he couldn't have thought he would ever get the chance to witness or learn. Not from a child like me, at least.

I knew this new knowledge would help him grow further and maybe he will improve this spell on his own, creating his own perfect version.

I would love to see that too, so it wasn't a bad deal at all.

I was... we were in a profitable position.

"You bastard..."

Rein knew me better than the headmaster, so she understood I was aiming for this very opportunity.

She was amazed, the look on her face was adorable, and the headmaster, who understood the situation, was even more astonished.

"Hahaha. You two are quite the fun ones. They will definitely like the two of you."

The headmaster was laughing and there was something mysterious in his voice.

He mentioned someone, and I knew he wasn't going to tell us who he was talking about.

We will know eventually, though. Anyway...

"Ok then. Let's finish this and go back or else your mom will slice me into fine pieces."

I had no doubt that she will so without any more words; he snapped his fingers.

-Snap!

The corpses of the demonic beasts, the demonkins, and the demon vanished.

And at the same time, a magic circle that was even bigger than the last one appeared in the high sky.

"Cleansing rain..." I mumbled as we looked up at the changing sky and observed the magic circle.

Now this one really was high-level magic...
