"About four to five kilometers?! Who are you kidding?! Go ahead and attend your class first then we'll talk..."

Yumi didn't believe him which was quite understandable considering that the aircraft within this world was still in the developing stage. 

There wasn't even a proper combat airship that has been developed yet. Even a solid military air force was not fully established in several countries.

There may be a few but it hasn't matured due to the various focus of each government. 

Wallace was sure that the countries like Montego would focus on their Mage Tower while Maja would focus on their automatons. Each country has its own specialization and even if they have an air force, they haven't realized how powerful it can be due to the current peaceful era. 

Aside from that, there were tons of mana spells that could reach to the sky, and people on board of this vessel were deemed to be an easy target... This was also one of the reasons why Wallace released several engines that could surpass the speed of sound. This way, people can realize that the sky supremacy was still one of the best methods to establish power. 

"Sigh~ Alright... I'll just show you later on..." Ace felt that it would be better to show Yumi about his current work. 

Wallace planned to use the combat spacecraft they were building today to be used as a practice for the real deal. He wanted to build a Conqueror-Class Starship someday that would surpass even the Galactic Federation's starship.

To do that, he had to get used to incorporating Magic Technology within his works. 

"Show me?" Yumi asked as she was confused by this guy's plans... 

'He's already building his Steel Knights and yet, he still has time to build huge aircraft? He surely has all the time he wants, huh... Right, did he say that he was only about to build this thing? What would he show me then?' 

The girl was unable to comprehend this guy. She was already shocked by his current identity and now, she learned that he was actually preparing so much in order to fight against the future invaders. 

"Yes... Wait for my class to end. Let's go home together..."

Wallace answered as he headed to his classroom.

"Ugh... Fine... You should've calmed your mind after your class..." Yumi can only reply as she shakes her head after seeing Wallace return to his classroom.

Within the Headmaster's room, Percival and the others were having a different conversation. 

"Miss Chamber, what do you think about that Wallace?"

Percival asked her because as everyone knows, she was the most talented here in terms of practicing the Soul Arts.

There are cases that a person's aura or mana fluctuation can be faked with a high-level magic spell or mana artifacts however, Soul Energy could not be easily faked. 

Elaine and Percival were confident about their detection magic and they didn't find any problems with his aura or fluctuation. But as they remember the impressive feat that this person had done, Wallace may have actually created an artifact to dull their senses. 

"Everything seems to be normal on his Soul Energy. Although, he had gotten a bit weaker. I'm sure that it was truly Wallace... I don't think that someone was impersonating him."

"Haaa... That's impressive then. Flowing Spirit, huh... Do you guys know about it?"

"I've only heard about it. Right, I've seen it in an auction before..." Clint suddenly said as he told them about the auction that has occurred in the capital.

Secret Arts were a hot item and no one would easily sell such valuable items. News about these products was always a huge deal to many collectors and researchers who wanted to identify the origins of these mysterious techniques. 

"We don't have a way to contact Sir Slaine or Wallace... Do you think that he has a method?"

"I don't think so... He already explained that they have different minds and he was also unaware of whatever that has happened in the northern continent." 

"Anyway, make sure that this information only stays within this room..." Percival said gravely as he looked at everyone.

They were not sure about the details, but an ability to clone a person and have almost the same flesh, similar mana fluctuation, aura, and soul energy would covet many people's greed.

Although Percival and the others doubt that anyone can just easily replicate them, they still couldn't help but worry about Wallace's safety if the information was leaked. Those people would surely find a way to get their hands on such valuable Secret Arts and make it their own. 

"Yes... That's obvious."

"Of course... I can keep secrets."

"Just in case, I'll also monitor him whenever he's at the academy."

"I think Yumi can handle that if we needed to monitor him outside..."

Elaine suggested as she was well aware of that lady's capabilities.

Everyone agreed on it as they ended their conversation and continued to discuss the real reason they were gathered here. 

"About this Mana Corruption... Do you think Wallace can actually? That guy seems to be unpredictable..."

"Ha~ He's only a kid. Even though he's intelligent and seems to be mysterious, his main talent was his Artifact Forging skills and that secret art was most likely due to his recent involvement with Sir Slaine." 

"You're right... Anyway, we'll first try to consult the best Mage Doctor we're aware of before trying some other means..." Miss Chamber said as she concluded their conversation.

They've already asked assistance with different Mage Doctors and even Dr. Mao with them was unaware of how to resolve the Mana Corruption. 

Apparently, their best option right now was to consult a Mage Doctor that specializes in all three paths of this profession, the Enhancement, Alteration, and Mysticism. 

They first thought that this Mana Corruption was only a type of disease that could affect the status of someone's Mana. But after doing some tests on it, they have discovered that this corruption can probably be a boon or bane depending on how it was handled. 

'Wait... If Wallace and Sir Slaine stayed within that tower for a longer time, will they also have the same problem?'

Percival was suddenly curious about those two mysterious and powerful people.

Wallace was barraged with questions after returning to his class. After all, several important people just went to their room and brought him to the headmaster's room.

They were not worried about him being reprimanded but they actually believed that he was commended for something.

He brushed it off telling that it was nothing important and refused to discuss it. 

It didn't take long before the classes for this day ended and for Yumi to pop out from somewhere and joined Wallace back to his villa.

"Oh? Is this Avalon?"

Yumi asked after she saw that the driver in Wallace's car was an automaton that was dressed as a human. 

She wouldn't miss this obvious detail. 

"Hello, Miss Yumi." 

It was Avalon's familiar monotonous voice as Yumi smiled after being greeted. 

They traveled smoothly and it didn't take long before the lady saw the previous desolate mountain where the villa was situated has now turned to a completely different site.

"What's going on here?!" 

Ace didn't answer her as he leads the lady to his villa and to have a quick rest before he would show one of his finest creations, the Excellence.
