Unsold Slaves Returned as Heroes - Unsold Slaves Returned as Heroes chapter 48

48. This is the theory called infinite mana bug

It’s quiet.

By the noise canceling magic, the voices of any of the spectators in the Colosseum are drowned in the atmosphere.

But looking at their expressions, it sounds like you can hear them in your ears.

Cheers, screams, responses, cheers.

All the audience’s eyes are directed at the six orange magic circles floating above my head.

“The 6th hierarchy, realization of the spirit realm.”

Six magic circles are placed through exploitation of slaves. It is full of mana for circulation.

Even a magic ignorant like me can arrange the high-level magic circles correctly without any knowledge.

But that’s all this skill does.

This is the process called activation in magic.

Now all we need is a cast.

Even if you hold a sword in your hand and know swordsmanship in your head, if you don’t have muscles, you have no choice but to stand still.

In order to move from invocation to casting using the same principle, magic’s own muscles and magic power are needed.

It’s a law to train that magic all your life, but when everything is ready like this, it’s said that you only need a little tricks to cast it.

If you compare it to swordsmanship, it feels like holding a famous sword and holding the master swordsman next to you as an instructor holding all the posture, and I only need to adjust the angle and drop my arms.

It’s quite reassuring because Tia also cast magic power enhancement on it.

Of course, it’s very difficult since it’s 6th, but since I practiced with Tia all night, there’s no reason to complain.

Draws dozens of auxiliary magic circles. It fits between the main magic circles. So as not to mistake the direction of rotation.

Every time the pieces fit together, the gins run beautifully like a conveyor belt in a factory machine.

“Mmm.”

From noble mtl dot com

My hands are shaking slightly. In response, the main magic circle is also about to shake.

I can’t mess with it here.

Tia now has a different venue for her own recital. She stopped her presentation and told me that she would help me demonstrate her magic. If I miss her recital because of me, it’ll be a joke.

6Th rank. Right below the 7th hierarchy, the limit that humans can reach.

It is said that those who reach that realm will write their names in history as heroes.

That’s why this cast is never easy just because it can be triggered. Especially for me who lack understanding of magic.

But I will definitely do it.

Spin, accelerate, recite.

Complete all processes calmly. Lastly, review to see if you missed anything.

I clenched my fist at the end.

Kwaaak!

The casting is complete. The magic circle that was accelerating the rotation spreads throughout the arena.

―Faaa!!

The next moment, the world was colored.

A Colosseum made of earth, sand, and bricks.

The simple lecture hall installed above it is nowhere to be found.

Birds are chirping and waterfalls are pouring. There was a light fog, but there were fireflies floating everywhere, so it was as bright as daytime. Each and every object that makes up this space is a spirit.

Here and now, the spirit realm has been summoned.

Someone calls Dowonhyang.

It is a fantasy high-ranking magic that realizes the space of another phase dimension into reality.

“Oh, the spirit realm! Professor Pedia. I am seriously astounded now!”

The president gave a lively laugh as he wiped his forehead with a handkerchief.

“Ha ha ha! After all, Professor Pedia! The day will come when I will see all the spirit realms alive!”

“Ah, long time no see….”

Band had fun like a child, and Mulan seemed to be deeply impressed.

The audience is also busy looking around. Seeing and touching the spirits full of surroundings is amazing.

I continued the lecture.

“As you can see, if you borrow future mana, even a 1st tier magic user can use 6th tier magic.”

The president’s smile hardened slightly. He seemed to remember what my lecture was about. He hurried over to me and whispered in my ear.

“Professor Pedia. Isn’t this a bit dangerous? You mustn’t disclose the skill of using dognaso or magic by raising it by 5 tiers. The continent will be ruined!”

“Don’t worry. Trust me and watch the lecture to the end.”

I understand the president’s concerns. If this theory applies to everyone, there will be a lot of confusion.

“Ugh, hmm. I have a question for you.”

As I returned to my seat, the president asked me.

“Shouldn’t the mana borrowed from the future be returned someday anyway?”

“As explained before, when the deadline is up, you can rent it again from the future.”

“If you keep repeating it over and over again, won’t it end someday?”

“Time is infinite.”

“Isn’t that the same as saying that mana is infinite?”

“You saw it correctly.”

“Huh….”

Should we attack Pelia soon?

“At the present time, there is no need to increase the efficiency of mana or magical power. That’s an inefficient action. The mana of the future is infinite, but is there a need for that?”

―Hey!! Hey you cheater!!

I could hear Felia shouting from her waiting room. She must have been impatient that her own lectures had been sniped.

“This theory is called [Theory of Multi-Time Mana Hire]. The basic formula, in summary, is: Oops, I can’t write down all the detailed formulas because the whiteboard is so small.”

I wrote only part of the formula on the whiteboard. This is what Sersi has put together.

Magicians, especially the Nation of Darkness, couldn’t stand it because of the tantalizing taste.

“For more details, please refer to my thesis to be announced later. With that said, I will end the lecture.”

You snapped your fingers. At the same time, the effect of the realization of the spirit realm ended and the arena returned to its original form.

The noise canceling magic is canceled. A huge roar hit my ears.

“Crazy! What a crazy theory!”

“The spirit world is dope!”

“Cool!!”

“I am not a slave trader, but a great sage!”

“Pedia! Pedia!”

I went down the stairs and went back to the waiting room.

At the arena, six crystal balls that recorded Pelia’s lecture and me were put up, and the auction was ready to begin.

When I entered the waiting room, Felia jumped right at me with a dash of energy.

“Hey! Where is the nonsense… ! Tell a plausible lie! What kind of professor are you!”

Tears welled up in Pelia’s eyes, probably because she was very angry.

“I didn’t lie. There are no loopholes in the theory.”

“Mana is different from the scraps of paper you wrote on! There are real things! How are you going to borrow that from the future? It costs more mana to open the space-time passage!”

“It is the role of practitioners to turn the theory into reality. Then how would you explain the 6th tier magic I used?”

“Mo, I don’t know about that! Are you a 6th level ?”

“A 1st level magic user.”

“If that theory is true, you are a brainless bastard. Do you know why I didn’t publish any research results and didn’t go to the Mage’s Tower?”

“I am not interested.”

“Professor Pedia!”

The president entered the waiting room. He asked in a serious tone.

“Can we proceed with the auction as it is? Your lectures and theories you presented were excellent. Too great It might change the game of magic altogether.”

“If another country obtains the video of the lecture and analyzes my demonstration, the wizards will become too strong and become weapons, and the war will accelerate.”

“Knowing that… !”

Felia was making noise, so I held out her hand to stop her.

“No problem. This theory cannot be applied in practice.”

“Cannot be applied?”

“Yes.”

The lecture I just gave was something I read on the wiki sometime ago.

Not the wiki you have now, but the original work you saw before being possessed.

That was also a DLC item.

――――――――――――――――

World of Endless / Demon Queen’s Revenge / Pre-Release Information

…

3. 2Nd beta test

…

3.4 Infinite Mana Bug Abuse

It was only belatedly revealed that some users abused the infinite mana bug during the 2nd beta test.

A new system [Mana Rental] Has been added to this DLC beta test.

It is a system that can be used in advance on the condition that mana more than mana is returned later, and if you run this in a newly created multi-account, it becomes a mana block (…) like a card turn block, allowing one character to use infinite mana.

Surprisingly, the incompetent production team couldn’t fix this bug, so they ended up deleting the [Mana Rental] System from the regular release. (The actual data source is there!)

…

――――――――――――――――

In other words, the theory I presented is a technology that is ‘impossible without reason’ because the principle remains but has been deleted.

In this world, the act of ‘borrowing future mana’ is impossible.

If you only show the theory, there is a possibility of defeat because the impact is small, so I inserted a demonstration. With the most impressive magic.

“What do you mean? So, you mean that your lecture looks nice but the contents are tin, Professor Pia?”

“Exactly. It is not easy to present research that could become a powerful weapon to the world.”

“You, I was thinking about everything… ?”

Felia glared at me with her complex face. The president seemed to be worried about something else.

“No, then your reputation as a professor is in trouble!”

“The theory itself is correct. It’s just not feasible. It will take several years before the countries that bought the lecture videos analyze them and decide that they are not practical, and even so, I am a pioneer in the theory, so it is not an achievement.”

“Professor Alencia, is that true?”

“That… I’ll have to do more research to find out….”

Felia swallowed the answer as if she didn’t want to admit that I was right.

“Mmm. Since you two said so, I know there is no problem. However, from now on, please give me some hints about the content of the lecture. My heart can’t stand it.”

The president let out a sigh of relief.

“Wait, then how did you use the 6th tier magic?”

Felia glared at me with her suspicious eyes. I shrugged her shoulders.

“It’s a secret.”

Felia opened her mouth in amazement.

“hahahaha, since he is a master of that kind of swordsmanship, there’s nothing strange about what he does. Then will she go see me at the auction? Thanks to you two, it will be a big help to the academy budget.”

“… It’s okay. See or not.”

“I will check. I want to accurately calculate the amount I will receive.”

“I knew you would come out like that. Let’s go.”

When I went back to the arena, Pelia’s crystal ball was being auctioned off.

The same item is auctioned three times over. The first crystal sphere had been won by the Nation of Darkness for 10,000.

But in the second case, the Nation of Darkness kept bidding and raising the price.

“You are bidding on the same video again.”

“That’s why Professor Alencia’s lecture is a valuable formula. No one here can understand it all at once, so a recording is essential. The Nation of Darkness intends to monopolize the formula.”

The Nation of Darkness also won the bid for the second crystal ball for 12,000 gold coins.

The third one went a little differently, but the Imperial envoys competed in sweat and bidding up to 15,000.

“You overreacted. It’s probably the whole budget. If you don’t bring any, you’ll be scolded by the emperor.”

The Nation of Darkness held a meeting among themselves and gave up the bid. In the end, one video of Pelia was handed over to the empire.

Next, it was my video.

―Nation of Darkness, stop! Are there any more?

Hmm.

An interesting picture came out.

“I’m thinking of monopolizing Professor Pedia’s crystal ball. That’s why Genga gave up Professor Alencia’s last crystal ball!”

The Nation of Darkness won the bid for two and entered the competition for the last one, raising it to 30,000 and succeeding in monopolizing it.

I’m going to use it for war, so I’ll shed bloody tears when I realize later that it’s not worth fighting for.

“117,000 For six crystal balls! Can we build another tower? Professor Pedia’s share is about 30,000.”

“Thirty-two thousand hundred.”

“hahahaha, that’s correct. Pay immediately Congratulations on your win.”

The auction ended satisfactorily. The match against Pelia also ended with my victory.

When I looked around the audience, I saw students cheering and cheering for me.

At least, it was quite reassuring to think that they were completely on my side.

I don’t know why they’re holding bags of gold coins in each hand.

“Professor Pedia! Show me the spirit world again!”

It’s a water pipe like Shion, but the students who study dungeons also congratulated me on my victory. I am confident in the direction of the Dungeon Studies lecture and feel proud.

I greeted the audience again and left. As I walked down the aisle, Felia glared at me with her disapproving eyes.

“Take it.”

As if giving up, Felia rolled up her sleeves and blew her mana. A thin and intricately engraved magic circuit appeared.

I thought he would rebel a little more, but it was quite unexpected. Pina must have been the result of training, but she didn’t seem very obsessed.

“Isn’t that something that can be easily ported?”

“… I have it ready.”

From noble mtl dot com

“Then I will accept it without hesitation.”

After she finished speaking, Felia took her small hands and crossed my arms.
