The service of designing one's own training grounds according to their wishes was actually quite liked in the game. Although it was slightly limited to some extent, it was an enjoyable experience for players who like to feel like they are living in the game world itself.

However, experiencing that in real life is so much better.

The place I have chosen was close to nature itself. The reason why people with spatial magic attributes are sought is related to the things like these. Since with the existence of spatial magic, you can design a magic tool that can customize such a subspace. However, it has different attributed mana in it as well.

Anyway, this magic engineering is a little complex for me to understand its structure right now, so let's leave it like that.

Starting running in the midst of nature made me clear my head. The last three days were quite hectic, considering my transmigration, my awakening, the attack on the church, and the legacy Austin left for me. All of them happened one after another.

Although I am proud of my mental strength, I was still starting to get tired slightly, so this running without anyone interrupting me cleared my head and made me think about my goals and my situation with a serene mind.

'Now, although it might look like sealing my mana core is a bad thing, it is actually a blessing in disguise. I can turn this into an advantage. Although people hiding their mana rank is not unseen, it is still a rare thing. It also requires high proficiency in using mana.'

I thought while slightly lowering my pace since I was getting tired.

That is also the reason why people would not be able to assume that I have awakened my mana core at all. At that time, if not for the distraction of Adelyn's mind, she would probably have noticed my awakening. But since my mana trace was still being formed at that time and I had awakened a day before, she hadn't noticed it. However, that wouldn't be the case if I kept improving my mana core. She would eventually notice it, although I doubt she would do something about it.

However, since nobody noticed me awakening my core aside from Diana, that would be a hidden card for the future as well. Coupled with my reputation, I have a chance to surprise the enemy if it is necessary to do so.

It is also a good source of motivation for me to awaken my Aura. Although, it is very hard to awaken aura while developing your mana core at the same time since the feeling of Aura is certainly close to the feeling of Mana, which would make people confused. However, since my mana core is sealed, I can awaken my Aura more swiftly, albeit it will hurt quite a lot.

Thinking like that, I reached my limit and stopped running as well.

"Huf, Huf, Huf. Sigh…. This guy, couldn't you just have a basic body? Even a normal body would do. Just why did you have to be this weak?"

Between heavy breaths, I mumbled in a slightly irritated voice.

Although my legs are pretty tired, my upper muscles are still fine.

Therefore, without changing the environment, I started doing some push-ups after I caught my breath. But this time, it was at a slightly slower pace than yesterday.

After that, I repeated the routine I did yesterday in my room until I deemed it enough.

With sweat all around my body, I stopped.

Since my body was all tired, I ordered a stamina potion from the spirit of training grounds.

"Aura. Give me a stamina potion."

"Understood."

Following her words, a bottle of transparent liquid appeared before me.

/GULP/

And without waiting, I gulped the whole potion to the bottom. The moment potion entered my body, I started feeling relieved. The feeling of tiredness started disappearing as well, and it didn't take too long for my body to completely return to normal.

Although I don't know how to explain this interaction from the perspective of science, it seemed like developers didn't know that either. They just said 'magic' and left it like that.

Anyway, the existence of a magic potion is the reason why I did a bodyweight workout before I trained with my sword. Since I could just return to normal, why not do it?

"Aura, change the scenery to the regular one I have been using before."

"Understood. Please enter the shining box."

Although training my sword in the open-aired atmosphere looks good, I wanted to remember the training I did with Austin in this place.

After my command, the scenery returned to normal. Slightly metallic walls, grey ceiling with fluorescent lights(?) hanging on them. It was pretty much looking like a gym.

Taking my position, I started recalling those memories from the past of how we trained with Austin, the effort I put in, and the pain engraved on my very being.

Drawing my long-awaited companion from its sheathe, I took the position of fencing. Since the swordplay of the Augustride Family is based on speed, the rapier is mainly held by one hand.

/EXHALE/

/SWISH/

With my left hand on my back, I started stabbing the air in front of me. Since it has been quite a long time since I have trained with my sword, reminding my body of the basics is my goal for the time being.

With that in my mind, I kept swinging my sword, thrusting into the air, until my right arm was numb from the feeling of tiredness.

Generally speaking, the strong point of the rapier is stabbing. Since the blade part itself is like a needle, when attacked, the pressure force is concentrated at a very small area which results in very high pressure.

In the earth, this is invented as a countermeasure for the knights with heavy armor since it is pretty hard to cut heavy armor made of metal with a slash. There is also the fact that it is related to elegance most of the time; therefore, it is also perceived as a show of nobility on Earth.

However, it is slightly different in this world. The reason why the rapier is chosen as a weapon is that it allows lightning attributed magicians both flexibility and the point-strike destruction at the same time.

Anyway, after my right arm went numb, I didn't stop training at all. Since Austin trained Callius to be ambidextrous, he forced him to train his left side as well.

Therefore, after picking up Nihil with my left hand, I started swinging and thrusting as I did with my right hand while losing the sense of time at the same time.

In the end, both my hands went already numb from all the swinging and thrusting I did, and at the same time; I started feeling really hungry.

/GROWL/

And the growl that came from my stomach was proof of that.

Deciding to check on the time, I asked the spirit.

"Aura. What is the time? For how long have I been training?"

"It is 10:30, Lord Callius. You have been training for five hours straight."

When I heard the time, I realized I had missed the breakfast.

'Hmm, I should have set the alarm or something. That way, I wouldn't miss breakfast. Well, it is not that important anyway.'

I thought while leaving the training room.

"I see. I will take my leave."

"I have recorded your training with swords. Would you like to check it, like previous times?"

"Hmm. I will check it after I finish my breakfast. Don't let anyone use this training room, and never show my records to anybody else."

"Understood, master. Since you are directly authorized by the Duke Austin, your records will not be shown to anyone."

"Good."

After confirming that, I left the room and went to take a shower. Since no matter how hungry I am, there is no way I would be able to walk into the mansion while reeking the scent of sweat.

However, from the looks of it, with the restriction on my body lifted, my body finally started showing the fruits of training. My muscles are all pumped up right now, so I look quite chiseled, albeit the wimpiness is still there.

After taking a shower and cleaning my body thoroughly, I put my formal clothes on and started walking towards the mansion.

/GROWL/

On my way to the mansion, my stomach was grumbling from time to time.

/GIGLE/ /GIGLE/

Hearing the sounds of giggling coming from the maids, there was no way I would ignore it.

Turning my red eyes to the maids, I activated my [Tyrant's Aura].

"Hieck!"

Getting intimidated by my gaze, they turned back, escaping from it.

Although this is just bullying, since it satisfies my ego, why not do it? It is quite funny thing to see their scared expression, to be honest.

After ordering a tasty meal from the chefs, I went to my room. Since I don't have anything else to do aside from training for the time being, I need to make some preparations to increase its efficiency of it.

'There were a lot of things that would enhance the physical training of the player in the game, just like I did while awakening my mana core manually. However, this time it will cost quite a lot for me to awaken my aura. Since it requires consuming a whole dragon heart.'

I thought.

'If not, I will need to do it in a painful way. We will see what I can do.'

Thinking that my meal had arrived, I started eating….
