E - Rank Hero In Another World
Chapter 92 - Magic Weapon

Several months have passed since the exchange between Leo and Roselia.

And now, his artificial microscope has obtained many improvements little by little. Make it produce a better and easier to see shadow, as well as the focus and height settings of the lens.

On the other hand, Leo is still busy studying the Runic dictionary made by Roselia itself. A book called "Rune and its Application Towards General Use" is about 478 pages thick.

Where the first 73 pages explain the way of writing, how to read, rules about language and grammar, and the meaning of each letter and word formed by it.

With a total of 32 Runic letters, a complex arrangement of languages can be formed from all of those letters.

Even memorizing everything takes a lot of time. Not to mention the next 405 pages that explain the application in everyday life and how it is composed.

But Leo has absolutely no problem with this. That is because this book really explains in detail what Runes are and how to utilize them.

In fact, Roselia made and wrote all of this herself. A rune of his own creation with his own grammar and rules. Even more terrifying, once applied, the rune could function according to what was written.

That was enough to make Leo admire the genius possessed by Roselia. It's just....

'Such genius is not even included in the skill huh? Well, of course if anything I've definitely taken it long ago.' Leo thought in his heart while looking at Roselia.

"Leo, are you having any trouble understanding this formula?" Roselia asked as she pointed towards the writing on her blackboard.

"none. Just continue with it." Reply Leo briefly.

"What about you, Selene?" Ask Roselia again.

"Law.... Maybe I want to make sure I get back. When you mentioned about Mana changes with a pentagram it was worse than a hexagram. Does this pattern apply to other quantities?"

Roselia smiled at the question. He answered immediately too.

"I'm glad you noticed. As you can see, on this pentagonal pattern...."

Their lessons continue. With Leo currently learning two things at once. The Rune book belongs to Roselia and also lessons from Roselia herself.

Of course, Selene helps Leo by recording all the details he might miss.

A few months passed again. Leo and Selene begin to understand the essence of magic itself, and are gradually able to answer the mysteries that lie in their heads.

Not only that, Roselia also taught Leo and Selene to maximize their magic capacity. Making the status of Magic and Mana they both increased at least 2-fold for Leo and about 40% for Selene.

And this time the lesson....

"You understand? At its core, magic is your own imagination. But it's easier said than done. For example, imagine the shape of ice.

Do you know how the structure is formed? Why does ice become ice? How temperature? The violence? The colour? Another trait? In making a powerful original magic, you need to have complete knowledge of it." Clearly Roselia at length.

He is seen writing on the blackboard about the various physical and chemical properties of the various elements, as well as what makes them come into existence and manifest.

On the one hand, Leo still listened to it carefully. But in front of him there was still a thick book about Rune that he could not even finish because of the complexity of the contents of the book itself.

While Selene looks to pay close attention and record all the information needed neatly.

Occasionally, Selene's figure is seen raising her hand to make sure or ask something that is still not understood.

Or when Leo pushes his legs lightly towards Selene's feet, it indicates that Leo does not understand about it.

And when the sun has reached its highest point, Roselia will stop the lesson and give the practical task to both of them.

Most of it is just to try to understand the ancient runes that cannot be known the exact number and meaning of each letter, in contrast to the runes made by Roselia herself.

At that time, Roselia will continue her own work. Where this time he began to observe things with his microscope and record all the results neatly in a paper.

Although, all of his work is still stored for himself and has not been uploaded at all. Roselia just wanted to know. That'sthat's all.

Some time....

"Leo, can you come in here for a second?" Roselia asked who was still facing her microscope.

"What's wrong?" Asked Leo who immediately backed out of his current job to walk towards Roselia.

After a while, Roselia pointed at the lens of the microscope while asking Leo something.

"I slightly modified the lens to see in a smaller size. Then I saw this thing in the nucleus of the cell. Is that what you think?" Ask Roselia.

Leo immediately brought his face closer to the lens to see what was inside the glass.

And what he saw....

Only white with a slight blackish tinge around and blurry black patches.

Leo immediately understood that what he saw was a chromosome, or a strand of DNA itself. Just as he had seen before at school. It's just, the picture times are too blurry and clear. It's almost invisible.

"Hm.... I think this is the smallest part of a living thing. It's just, it's too blurry and clear to see. I advise you to color it before you see it." Obviously Leo.

"coloring it? By what?" Ask Roselia.

At that moment, Leo woke up. He does not know what color should be used to color up into the cell.

What he did was simply dip a piece of cell into a red liquid before looking at it in a microscope.

As for the color itself....

"Either.... I don't know, maybe you can try. But to my knowledge, I firmly believe that it is the smallest part, arguably the constituent of the living being itself.

If you can uncover the secret behind it.... I don't know. I think the opportunities are vast." Reply Leo.

Both of Roselia's eyes seemed to sparkle with a very wide smile on her face.

"Is that so?! Thanks Leo! I'll do it soon!" Reply Roselia while immediately running towards the warehouse.

For over 5 months of studying under Roselia, Leo knew that the girl was the type of person who liked to solve problems with her efforts. As long as there was a clue, it was enough for him.

So is the moment.

'Good, but unfortunately I don't know more than this. I'm quite sorry for myself who used to not even be able to go to college....' Leo thought in his heart.

At this moment, Leo only assumed that Roselia's new microscope and hobby was merely a fair exchange for her to acquire rune knowledge.

He has not realized, that his actions this time which he considers as trivial, can change the direction of the future of this world.

After a while....

Leo again walked towards his workplace to pick up an iron rod with many beautiful blue rune inscriptions.

You could say as the first work of Leo after all this time learning about the rune made by Roselia.

Leo is seen walking towards the spot with a stone floor as well as a wooden doll with iron armor at the end. Slowly, Leo directed the iron rod towards the wooden puppet.

After ascertaining the direction of his target, Leo then placed his thumb right in the middle of that slightly empty part of the Runes. And quickly pulled it back.

In a flash....

'Blayr!'

A fire magic immediately shot towards the wooden puppet. Gave a small explosion enough to scratch his armor.

But nevertheless....

'Still less. With just this alone, I won't be able to defeat my enemies in the future.' Leo thought as he stared intently at the iron rod.

Perhaps that weapon, was a magic weapon that resembled the world's first firearm. The original work of Leo himself.

Leo was not upset at all. Because he knew he was walking in the right direction.
