Yes, it's not skill books. But training manuals.

'It must be auras!'

Why? Because aura is not a skill, it is something you have to comprehend and learn from the ground up.

However, there’s something weird here…

"Uh, teacher?"

"Yes."

"I can understand the healing skill, but… why did you give me two training manuals for auras?"

Right. It’s weird that she gave me two instead of one.

"Because I want you to decide which one you'd like to learn."

That's a difficult question.

"It's just… you're so talented that I had trouble choosing which aura would fit you best. So I'm stuck between these two…"

"I see."

It's not surprising, considering how many aura there are.

‘If I were to explain what aura is…’

It was similar to the profound energy you'd often find in martial arts novels.

Aura is the direct opposite of mana in almost every way. Suppose mana is a power that [Changes] something from the outside. Then, aura is a power that [Strengthens] something from the inside.

Mana exists everywhere in nature, is calm, has its own mana veins, and accumulates in your circle or core. Aura only comes from a practitioner, is very destructive, and generally travels in your aura veins.

Aura is a power that strengthens your body from within. Its applications are many, and aura can also enhance the inner characteristics of weapons and items you’re holding.

The effect also differs depending on the kind of aura you use. Some auras increase your affinity with the cold or hot attribute, others are optimized for martial arts, and there are even auras for dual cultivation.

'I can finally learn aura.'

This is also the first time I, a modern man from Earth, will learn something like aura, so I'm excited to experience it firsthand.

For now, my priority is to choose which of these two aura to learn.

"Can you tell me more about the two?"

"Of course."

A case of content theft: this narrative is not rightfully on Amazon; if you spot it, report the violation.

Bianca then explained both auras to me. One was Bianca's aura training method, and the other was the current Dragon Lord's method.

Bianca's aura focused on purity and had the light attribute. The purer the aura, the more reactive it is to inner characteristics, making it easier to achieve a greater strengthening effect even with a tiny amount of aura invested.

The light attribute was also the rarest kind. Because the learning conditions are very harsh.

"Can I even learn your aura? Don't I need to have a pure body, pure heart, or pure mind, to learn the light attribute?"

That's right. The condition to learn a light attribute aura is for you to fulfill at least one of those conditions

A pure body can be achieved by restraining yourself from bodily desires. Like consuming meat, alcohol, and certain foods. You also need to restrain yourself from doing almost all kinds of sexual acts.

'The Saintess is like this.'

It was a way of life that I couldn't emulate, even if I wanted to.

'Alcohol is fine, but not eating Bulgogi and meat is too much.'

Above all, sexual acts. I have lived as a male until adulthood, so I know just how hard it is to control your sexual impulses.

'I'm not saying females have it easy, but…'

I think there are too many things that can arouse a male's sexual impulse. Either way, I'm not confident I can do it.

'As for the other two conditions…'

Purity of mind is to achieve a Buddha-like state of enlightenment.

'How do I even do that?'

I don't think meditating under a tree or a waterfall will help much. And that's as far as my mind goes when I think of ways to achieve this Buddha-like state.

So that only leaves me with the last condition…

"Purity of heart. Do I even have that?"

"Yes!"

"Really? So that means I can learn your aura?"

"Of course! If it's you, my disciple, then you can learn it."

It seems Bianca was pretty confident about it. But…

"Teacher,"

I voiced my doubt.

"I'll say this in case you don't know, but I'm just a normal human. I am ordinary in all aspects of my personality. I can get angry, I can wail in despair, I can lie, I can curse someone and even try to kill them. I am not someone with a pure heart at all. No, in the first place, I don't even think of myself as a good person."

An ordinary person who lives an ordinary life on modern Earth.

Even if the body is that of Raon Eva, I am the one using it. So, it's inevitable that this heart will change depending on my actions and words.

"Even then… are you really sure I can do it?"

Bianca smiled softly, her eyes shining.

"My disciple. It seems like you are misunderstanding something."

"Eh?"

"Pure heart is not about having or not having certain emotions. It's not even about refraining from taking certain actions. If that were the case, then my heart must have turned black when I was trying to kill Nicht out of anger back then. But take a look, my disciple. Look at my heart."

Bianca thumped her huge breasts. It was amazing to see it jiggled like that.

'No, focus.'

I shook my head and activated my vision skill. At first, I had trouble seeing someone's heart since I hadn't learned how to do so until now, but Bianca gently guided me until I could.

And finally…

"...!"

I saw Bianca's heart. It was pure white. Not even a stain of black was found.

"How…?"

‘How do you have a pure heart even after trying to kill others?’

It was the moment my understanding of the heart changed.
