...-Roselia Workspace -...

Unknowingly, the sun had returned. Forced Leo to return to the academy with a face so exhausted.

“Master, are you okay?” Ask Selene curiously.

“Don't think of me. This is something that is needed.” Reply Leo briefly.

His eye bags looked much thicker and more black than usual. Even his gaze looked quite lethargic. However, a faint smile could be seen on his face that looked so exhausted.

Moments later, Roselia appeared out of her room with a performance that was no less bad with Leo.

His face also looked so exhausted with blackened eye bags.

“Leo.... I told you I can't sleep, right? You have to take responsibility.” Said Roselia while pointing her index finger at Leo's chest.

“Take it easy. I also need to think all night for this. By the way, this is what you need to see that cell.” Said Leo while giving a rough idea of a microscope.

He only used it a few times while he was in school. But fortunately because of the hard upbringing of his parents, he always paid attention and studied everything in earnest. Makes him still remember about the principles and also how the work of the microscope.

‘Well, in fact the microscope had been refined by Galileo around the 1600s. If I can't make it even after using it.... Hahaha..’ Leo thought in his heart while watching Roselia's figure.

Right now, Roselia was busy paying attention to the set of tools that Leo described on the paper.

“Lenses.... Clamp.... Glass.... Isn't all this.... How did you know about this?” Roselia asked who seemed a little suspicious of Leo.

“I used to be an academic too. Forget that little thing, as long as you can prepare the material then I can assemble it for you.” Reply Leo brushed off Roselia's words.

But without him knowing....

‘Academy? Wasn't Mr Leo also a slave earlier?’ Selene asked in her heart while watching Leo's figure in the distance.

Suspicion begins to grow as more lies are made by Leo.

He himself knows and understands this. Leo also didn't mean to hide forever. But atleast.... He must do so until He is strong enough to endure alone in the midst of this world.

“Alright, I'll find him. Today's class we will change the schedule and learn this tool.” Said Roselia who immediately walked over to find some tools and materials in her warehouse.

......***......

More than 4 hours have passed.

Leo tried hard to assemble the microscope with the equipment and materials that had been provided by Roselia.

Now, with his eyes that are almost no longer able to open....

“Successful.” Said Leo softly while looking through the lens of the microscope for the next time.

‘Although not perfect and not as good as what I used in the classroom first.... But this..’ Leo thought in his heart.

“Let me try!” Shouted Roselia who immediately shifted Leo's body to use the microscope.

What he saw was the arrangement of the leaf tissue. The leaves have been sliced thinly and then clamped in two thin glass pieces with additional water.

The image still looks quite blurry, even the shadows formed in the lens originally created by Leo are still imperfect.

But maybe....

This is the first time in this world.

One managed to see the simplest arrangement of the body parts of living things.

“Remarkable..” Said Roselia with her eyes wide open and tears beginning to flow.

His love for magic and science is deep. Makes her feel very touched by this tool.

“I've guessed the body is made up of something small, but I didn't think.... Even in it there is more?” Roselia asked who continued to observe the leaf tissue.

“Now it's your turn. Tell me what did you do to heat that glass yesterday? And what do some strange writing mean around it?” Ask Leo.

“Aah, the? It was a self-made rune, based on an ancient rune. His strength was extremely weak and could be said to be useless in the absence of a powerful Mana, unlike the ancient runes who had strength of their own.

But with that rune of mine, you can do some interesting things. For example, activate the heating magic on the table like I did before. Well though, the Board decided it was useless because it lacked strength.” Clearly Roselia while continuing to observe through the tool.

Selene who had not understood what had happened, now began to realize.

It's just....

“Master, it seems that this time the exchange is quite bad huh?” Selene asked in a soft voice.

But when he lifted up his face to see the expression of his Master....

“Eh?”

Selene looked surprised.

With an exchange as bad as this, even after making himself so exhausted, Leo only got a rune that did not even have the strength.

He should feel a little disappointed. Even Selene herself looked very disappointed and annoyed that her Master had to go through all these problems for the sake of something that was even considered useless.

But nevertheless....

Leo smiled very broadly. Even his eyes were wide open as if filled with a feeling of surprise and delight.

An expression that Leo had never shown before.

“Roselia, in other words.... Can you make that rune do anything else?” Ask Leo to make sure.

“Yes that. Another example, you could put your hands on that wall and the Mana stone lights in this entire room would light up. Although, it will take your Mana.” Roselia.

Leo's facial expression grew even more after hearing that explanation.

Hundreds, even thousands of opportunities were present in the rune that was considered useless. He was now beginning to think whether most of the people here had not thought at all about this rune opportunity.

Because with that rune....

“So.... Your runes are some sort of command line to run a certain magic?” Ask Leo one last time.

“So you can say that. Great also you can realize it.” Reply Roselia who now turned her face to look at Leo.

And Leo himself....

‘Bingo!’

He shouted with all his might in his heart. Trying to let go of some of her overflowing feelings of pleasure.

“Roselia, can you write down the letters, the readings, and the meaning of each word for me? I thought of something interesting with him.” Reply Leo.

“I've made the dictionary. You can grab on shelf D line 6 from the bottom and book 4 from the left, with a blue cover. But for what? Even the Council considers it a useless thing to waste a lot of time studying it.” Ask Roselia.

The answer from Leo is quite simple.

“You are one year or whatever, it is the most useful thing in this world right now. Roselia, you will see a great revolution in a moment.” Reply Leo with a big smile.

What Leo thought was simple. It may be too simple for many to forget.

It is a tool, which will activate magic instantly and quickly with the help of Mana. Neither from himself nor from any other source.

A tool....

It can be called a magic weapon.

If coupled with its ability to perform Enchantment.... Then the odds are almost said to be limitless.
