Chapter 144

“How did the experiment go?”

“It works fine.”

“Then it’s fortunate, but is it really effective?”

near the front door.

To test the performance of the barrier, I brought Professor Katrina and Wilein out. Kathrena asked in an anxious voice.

The pure white beams of light emitted from the magic cores of the four pillars converged exactly at the center, creating four triangular-shaped bluish curtains.

It’s a story that has always been told in fairy tales, so there’s been a lot of attempts so far about barriers, but almost none have been made properly.

“Can I use magic?”

“it’s okay.”

I shot a “Wind Blade” upward. The [Wind Blade] that collided with the bluish curtain… … .

No, it didn’t even collide.

“Isn’t anything happening?”

It flew right past the curtain, and the magic disappeared.

“Excellent.”

“yes?”

Wirain briefly expressed his impressions. Kathrena narrowed her brows.

“I couldn’t stop it, but it’s great… … .”

“It’s a one-way street.”

“you’re right.”

I nodded. Then, I took a few steps and cast 「Wind Blade」 from outside the curtain as well.

Empty!

This time it was blocked properly.

A bluish wave could be seen spreading throughout the veil, but the barrier remained intact.

“You block it from the outside, but it’s okay from the inside?”

“The professors have done a lot of research so far, so the data is sufficient. There is also a material called magic core, so His Highness made it.”

It prevents monsters from attacking from the outside, and transmits magic fired by allies from the inside.

The barrier and performance itself that Kanin creates in ＜Academy Summer Turge＞ are the same, but it is easier than having to have ten wizards cling to each core pillar to supply magic.

“However, since Summer Turge is built in a mountainous area, the space under the pillar is empty. If it had been flat, it would have been able to fill in the bottom as well.”

“It’s enough if you only deal with flying monsters. Good work.”

“I didn’t do anything.”

All I did was take out a long-awaited discarded document on the barrier from the professor’s research building and hand it over to Ai-nim.

The cheap magic core was improved by the professors, and it was Ai-nim who made it possible to create a barrier.

Wirain looked away from the barrier and touched the tree under the barrier.

“Did you say that you made this wooden pole as a freshman?”

“Yes. I am a student named Jerome.”

“I had no idea. I should have paid more attention.”

“I was hiding it.”

“You found out what I couldn’t.”

“That’s how it works.”

Wiraine smiled.

He always had a stern and rigid impression, and even when he laughed, he didn’t seem to be laughing. I don’t know what you’re thinking.

“Are you okay?”

“It’s okay.”

“When the mana is sealed, there is intermittent pain around the heart. There shouldn’t be any problems in daily life, but the people around you still don’t seem to notice, so it seems you’re paying attention.”

“Yes… … ?”

I was dumbfounded.

As Wierain said, sometimes without warning there are terrible pains in the heart.

It must have been a side effect of the sealing, I thought. When I was in the room, I coughed a few times and pretended nothing was wrong.

But how does Wirain know that?

“How does the dean know that?”

“Aren’t you quick-witted even in a place like this? Or maybe I’m not a big deal to you. I will go back.”

“Ah, yes.”

Wirain called Professor Katrina, who was fiddling with the barrier, and returned to the main building.

I wondered if he was going to leave without saying anything frustratingly. As I turned around, I heard Wirain’s voice.

“I only used 3-star magic on the barrier.”

“… … .”

“The seal is like that. It’s only Coltman and I who know how. I don’t know how Lady Yuxilla knew and came to find me.”

Yulain Mage Bruntelli, dean of Summer Turge, is the only one who knows how to ‘seal’ the magical powers of the fairies along with Coltman.

‘The stronger the magic, the weaker the seal becomes. Never use more than 4 stars, and do not use 3 stars as much as possible.’

That’s what the wraith said.

It’s strange to come to think of it now that the standard is presented accurately.

Above all, I’ve never seen Yurain use magic higher than 4 stars. Even in the Crisis of the Northern Wall, he only used 3-star magic.

So what?

I can see the dark blue hair of Wiraine, who is getting farther away.

Jerome also has blue hair, and many students have blue hair, so it must be roughly like that. Looking at it now, the color is too dark.

okay. When it comes to paint… … .

As if the original blue color was forcibly mixed with black.

“Boss.”

“Wow, what a surprise.”

It was a sudden voice from behind.

Jerome had just arrived. This guy calls me manager.

First of all, the title is the head of the technical department, so the manager is correct.

I don’t like this tone because it feels oddly old. Everyone calls Baeller a senior, so I think it’s better to use a different term.

“The preparations are complete. We just have to wait until evening.”

“Yes, it was hard.”

“I distributed my magic power in advance, so even if I die on the way, the pillar won’t collapse.”

“At most, it’s like a fly. Why die, man.”

I pressed Jerome’s head hard.

Jerome has a bad habit: he always assumes the worst.

If it’s good, the contrast is excellent, and if it’s bad, the fuel economy is poor.

“I am resting in the tower. Because you have done your part.”

“I wonder if that will work.”

“it’s okay. Aren’t you going to catch it?”

“It is.”

Jerome is also learning magic with the theory of imagination, but general magic is at a poor level.

In the first place, there is a unique magic system called growth, so it is difficult to adapt. I don’t expect to go there.

“Leave it to me. You will do well.”

“Then I’ll go back to the tower.”

“OK. After watching for two days, the academic schedule can go back to normal.”

The monsters invade in about two weeks.

Because it was not a short time, I said that I would teach students and refugees at the same time if it was judged that there was no big problem.

Even if they couldn’t go out of the barrier, students didn’t go out often during the semester anyway, so it was an urgent priority to increase meaningful combatants as soon as possible.

After sending Jerome away, I headed to the workshop that had been open for the first time in a while.

Neil also has a job as an advisor to the technical department.

There must have been a pile of work as soon as I came back, but I put it off and helped with the barrier.

“What’s more?”

“Oh, are you here?”

In the corner of the more complex studio, Nael’s head popped up.

It seemed like they were making a structure that looked like a tower, but at first glance it looked like they were making a toy because it was about the size of a waist.

“I think I saw this.”

“It’s a transmission tower model. It’s smaller in size and has the same functionality.”

“You were busy making barriers until yesterday evening, are you working again?”

“Huh, that’s right. I get anxious when my hands are resting. Aren’t all Aindarlocks like this?”

“… … It might be.”

Rather than having a workaholic gene, it was the fate of the family that Derek and Coltman had told me about. Neil doesn’t seem to know.

I asked while looking at the almost completed transmission tower model.

“Is this all over the empire right now?”

“yes. As soon as I came back, I installed it on the roof of the main building.”

“I heard you. That’s why the location of the flying type monster is being communicated in real time.”

Transmission towers were launched a little later than this, so they wouldn’t be effective until summer. It’s limited to the empire, so it’s useless in the bottomless cave.

However, as a result of my previous advice, the transmission towers were deployed earlier than planned. Because it saved money.

In any case, this allows you to transmit your voice over a long distance.

Right now, you can communicate with the Confederate Front in almost real time, so it can be seen as a great development.

“It was installed in the main building, so why are you making a model here?”

“Even if it’s a model, the truth is a little different. We made it smaller and increased the vibration output.”

“So that it can be used in a space with obstacles?”

“Wow, as expected, the younger brother knows right away.”

Hearing the compliment made me feel better.

I should try to get a better reward besides stroking my hair. I’m sorry

“The previous method was to shoot it into the sky, so delivery was easy, but this is a little difficult. For now, I’m thinking of sending it to the ground.”

“When this is done, can it be used in places like mines, for example?”

“That is what I am aiming for. Actually, the request came from the imperial family. So that we can communicate within the palace without having to send an attendant one by one.”

“It makes people spend money on places that don’t really matter.”

“Whoops, it’s up to you to decide how to use it.”

That’s what it says.

It is up to you to decide how to use it. Something came to my mind right away.

I’ve been making positive variables for this and that, but I thought maybe this transmission tower might be the key.

Riden’s Abyss.

A monster’s hungry ghost that sinks down and down without knowing the depth.

The reason for the difficulty in the thirteenth episode, which requires a small number of elite wizards, is that communication between groups separated from the inside is impossible.

But on the other hand, what if close communication with each other is possible?

“I need to think about this for a bit.”

“It’s welcome if your brother helps.”

“But don’t believe too much. Now that I’m older, I think my brain has become stiff lately.”

“You say sad things. Then my head will turn around already.”

I spent time in the workshop until the evening when the invasion began.

“How about arranging transmission towers and separate mediators at certain intervals?”

“Wouldn’t it be difficult to place if there was a passage that fell vertically?”

“Something like applying glue.”

“Um, but it’s still a cumbersome method… … . If there is more than one intermediate intermediary, all communication is cut off.”

Time passed quickly just by thinking of various methods and experimenting, and the sun was setting.

“I must go now.”

“Your sister is at ease. It’s not like I’ve ever dealt with one or two monsters.”

“okay. I believe in you. All of my friends look dignified.”

I could use 1-star magic, so I needed to use magic as a test.

Magic level 10.

Even 1-star magic cannot be overlooked. It will be more than enough to help with power.

“Then, as an encouragement… … .”

But before leaving, I hesitantly opened my mouth. It was also embarrassing to take it out of my mouth.

“Ahaha. Are you still missing it? My clothes are dirty.”

“When have I ever cared about that?”

“It is.”

Fortunately, Neil understood right away and got up. As I spread my arms wide, Neil came up to me and hugged me.

“Be careful, little brother.”

A warm feeling came through.

I can’t even remember when the last time was. If only I had a family.

Obviously, it must have felt like this.

“sure.”

I walked out of the studio with a brisk walk.
