Powerful container, huh? I think I can use the materials like the ones I made for the oxygen tank from the time I fought the All-seeing Eye.

"Sonia, can we awaken our Aura as well?" Kayla asked.

She was interested in Aura as well. Because of her lack of offensive power, she used a spike from earth magic as a rapier. If she has Aura ability as well, she will be more powerful.

"That's a difficult question. Back then, we have a way to know whether someone has potential in awakening their Aura or not. And even those with potential, only few percent of them actually managed to awaken their Aura. But there are some who actually doesn't have the potential at first, but somehow managed to awaken their Aura even though their Aura is much weaker than average Aura user."

Sonia explained. But why is Victoria listening closely as if she doesn't know it?

"Victoria, why do you act as if you don't know it? Shouldn't you be getting your potential tested as well? And why don't you know about it?"

"Well, I don't remember it. I do remember watching something interesting though." Victoria replied.

Then Sonia tells Victoria what happened in the past.

"We were being tested at the same time! How did you forget?"

"Actually, how was our master conduct the test? I only remember of seeing something good."

"He grabbed our waist, inject a little bit of his Aura into our body while looking straight into our eyes. How could you forget that? He said that if he could see the trace of his Aura in our eyes, it means we have potential to awaken our Aura. That was the method he learned from his master," explained Sonia.

"Ooh… so that's what it was. No wonder I felt like I watched something good…"

Seeing Victoria had a weird smile, I realized what happened.

"Sonia. Did you have other fellow disciple as well? Boys perhaps?"

"Hmm? Yes. We have several boys and girls training together. Although some of them didn't have potential at first, about two or three of them managed to awaken their Aura. Of course the most talented at the time was me and Victoria."

"…no wonder she was so happy."

"What's wrong?" Sonia asked.

"Victoria… she's… a weird girl who loves to watch men getting intimate with other men…"

"…no wonder she forgot about it. I remember how she intensely watching while master is testing other disciples."

Over a thousand years passed already and she never changed. I truly wish she wasn't like that.

Now I'm worried! She said that I'm her type, but in what?! Her type in her imagination for being with… other men?

HELL NO!

I should think carefully before I answered her confession!

"What's wrong, Roy?"

Kayla is worried about me who suddenly stopped talking.

"Nothing! Sonia, can I try that with everyone here? I want to see if they have potential or not."

"Not yet. Your Aura is still not good enough. If you're doing it badly, you might end up killing them. Master said that it need precise control over Aura to do it. Even some Aura user who's much stronger than master is unable to do it."

"I see. I thought I could finally build an army of Aura users for myself. Well, maybe in the future I can."

"Improving Aura ability takes a long time. Even if you trained hard, it might take you more than fifty years before you can do it. Everyone has different limit in their potential. Maybe you have reached your limit right now. Or maybe you can only grow after you reach 70s. The rate of aura users' growth are all different from each other."

Does that mean I might already reached my limit?

Doesn't matter. There are still many things I can do even if my Aura hits the limit. I can practice other weapon, using magic tools, improving my air and summoning element, and learn all kind of knowledge.

I guess I have to give up on building an army of Aura users for now.

This is my second life. I know by now that no knowledge is unnecessary. The ones that seems unnecessary at first, actually they were just knowledge that no one have found where they need be used yet. Even if they will never be used, they are important.

And I used my time poorly in my past life. I only learned things from rumors. Even the knowledge about magic control, I learned it because one of my patient told me about it. If at that time he didn't enter my clinic, I won't be able to get this far in this life.

"Well, is that all you two know about Aura?"

I asked both Sonia and Victoria.

"Yes. That's all I remembered. If there's other things I remember, I'll tell you about it." said Sonia.

"Good. Now about the one who killed the two of you. Tell me everything you know."

The first one who tells me was Sonia.

Just like what she told me before, she was seduced by the mage who ended up killing her. Before she died, the mage told her that he wanted to kill all Aura users.

"…for someone who seduces men easily, how can you be seduced by a guy?"

"…I'm weak toward playboy. That wasn't the first time I got seduced, but back then, I could still seduce them and make them be my lovers. But for that mage, he killed me after he learned everything I know about Aura. I don't even remember his name or his face."

How stupid. A seductress easily seduced? And she ended up being killed. That's a stupid way to die.

Next is Victoria. Just like she told me when we first chatted just after I summoned her for the first time. She already heard rumor of a mage who targeted Aura users. And so, she tried to run away. To a place where no one knows that she is an Aura user.

But she failed to escape the mage's grasp. She fought him for a while, but in the end, she lost. She asked him why he's aiming for Aura users, and he told her that he wanted to be a god. He doesn't want anyone to have power stronger than him. And he also said that Victoria is the last one.

Was that mage is the same one who killed Sonia?

No one knows. But there's a possibilities of that mage who killed Victoria and Sonia is the same. Probably, that mage killed Sonia first after asking about Aura, then started killing Aura users until that mage finally killed Victoria.

Then, I noticed that Sophie is thinking deeply about something.

"Sophie? What's wrong?"

"Hmm… I think I know that story. I have something similar in books I bought for Daniel to read. Let me get it first."

She stood up and went to her own room. We all sipping the drinks Lina prepared who knows when.

Sophie returned shortly after carrying several books.

"These are the books I planned to read to Daniel so he can learn to read and write. They are all fairy tales. And this one is similar to the mage Sonia and Victoria told us."

I remember now!

I've read that book before. I had it in my clinic in case my patients will have to wait in line for their checkup. Unfortunately, my clinic wasn't popular and I'm the only one who read the books.

The story is about a hero defeating evil villains. A common story for children.

Now that Sophie mentioned it, she was right. And this book is one of many books that tells about Aura. But I thought in the past that it was just a fiction.

Now I read it again, the hero is most likely that mage who killed Aura users and the villains are depicted to be humanoid using weapon and unique ability. Some of the villains' abilities is to strengthen their physical ability called Aura. And one of the reason why I first named it Aura before I actually know that it was really called Aura when I summoned Victoria.

It started with the hero mage returned home to see that his friend was seduced by a succubus and died soon after his life force is absorbed by the succubus. Then the hero decided to seduce the succubus and killed her.

"Doesn't this part very similar to Sonia's story?"

"But I have never seduced his friend! Even if I had, I never absorbed my lover's life force! I only absorb those who are too ugly in my harem. Wait! Maybe his friend is ugly." Sonia protested.

"This story might be related to the truth. But it was changed for entertainment so the author turned the mage into hero. Even the last villain in the story is one with multiple pairs of wing. Just like Victoria." I said.

"Does that mean…"

"Yes. History is being altered. But it might just be our assumption." I answered Kayla before she finished her words.

The one who killed Aura users ended up labeled as hero, while Victoria and other Aura users became villains.

This might be a real history, but it ended up as a fairy tale. I need to know more.

"Hey. If anyone here encounter any monsters or ghosts that can speak, ask them about Aura first. Who knows if they are actually Aura users from the past?"

At least I hope the next Aura user is a human being. I want to learn more about Aura and the one who hunted all Aura users.
