There was a reason why, in his past life, Callius as Aaron was successful as a student.

Because he had a very strong focus that would be very hard to break in most of the situations.

He could work for 14 hours straight and would be able to remember the things he learned even in the last three to four hours of studying, which was a very strong quality.

And that itself was showing its effects right here right now.

<Ding! Host's Mana rank has reached the limit for the one-star boundary.>

<Ding! Host's core is starting to attempt the breakthrough.>

Hearing the sounds of system notifications coming into his head, Callius released a breath of black-colored gas from his mouth.

"So, it finally began, huh?."

Mumbling like that, I started bringing out the things that I was going to use while breaking through the second-rank mage.

/FLICK/

But first and foremost, I needed to light a fire.

/SWOOSH/

With a flick of my finger, I conjured a lightning bolt from my hand, igniting the branches of trees that I brought with my telekinesis.

Thanks to the training I did for the past 24 hours without stopping anytime, there were a lot of tree branches I brought there.

And to be honest, my progress with my telekinesis magic was a lot better than any other type of magic I tried.

'Probably because of my innate traits.'

I thought.

Anyway, now that I had lit the fire, I started chanting.

"Aqua mirabilis, by the tides and the sea, bring forth your magic and hear my plea. Waterflow."

Although the mana used was a lot much than my telekinesis magic, still, the water appeared out of my hands and fell to the pot I had put on the fire.

'Now, let's start with the ingredients.'

The thing I am trying to do is something a heroine of the game had found on her own. Thanks to her unique type of fighting style that had both aura and mana usage, she developed a type of strengthening that was suited for those who used mana and aura at the same time.

'However, I will change your formula a bit.'

But, just because she was the one developed doesn't mean it was optimal.

In the real world, where science is cumulative, a person might have the idea, but some other would be the one that would mark the final rule….

Anyway, just like that, I started getting ready the ingredients.

'A couple of Creepy Tansy roots.'

Bringing out the bright purple roots, I flicked my hand.

A plant that would make the mana inside your core go adamant if consumed raw.

However, when it is consumed after boiling it and extracting its essence, it would make your mana core open itself, which would enable it to have mana inside more smoothly.

'Then, Phantomseekers magic core.' 

After that, it was the core of a monster that was one rank higher than you which had an attribute that used raw mana.

At least that was what she did, though I am a lot greedier than normal.

I will go for a lot stronger monster for my core.

Because the aim of this process is to strengthen your core by forcefully injecting raw mana of higher strength. 

And a Phantomseeker was just such a monster. It didn't have any attributes but used raw mana for its mind magic, and it was a 3-star monster that would rarely be found in this part of the world.

I will need to boil that as well since eating such core directly is not possible, considering I am not a beast.

'Let's see how strong my core is after all those times it took for the foundation of itself.'

With that thought, I brought the last piece for the process.

'Mana Sealing Liquid.'

It was an item that was highly used by magic engineers since it had the property to seal the mana inside one place.

Most of the time, when an item related to magic is developed, it would need an energy supplier, which in case, would be a mana supplier.

And to do that, you need to seal the mana of an attribute you would need to use in one place, which in the end, would require you to have a method that would seal the mana.

In this case, such liquid of anti-magic attribute is developed by the magic engineers, and now I will use that in order to seal the raw mana of the monster in my core.

In the end, even if you are not able to hold the mana inside your core, it would just escape from there to a lower-density place with diffusion.

However, now that we are sealing it, the mana won't be able to escape, which will make this process meaningful.

Just like that, everything was ready.

Boiled Creepy Tansy Roots, the Phantomseeker's core, Mana Sealing Liquid, every one of the required materials was here.

And the Dynamic Mana Pressure Point was a bonus for that.

Like that, I finished boiling the roots.

/GULP/

And gulped it in one go.

"Bughk…. It tastes like…."

Mumbling like that while slowly opening and closing my mouth, I grabbed the mana core of the Phantomseeker.

/GULP/

And gulped that in one go as well.

"Kurghk!"

And it was the most disgusting thing I had eaten in my life, and I almost puked that out, although at the end I was able to control my urge.

"Cough, cough, cough…."

/BURN/

After coughing for a little to shake this feeling off, I started feeling the hot sensation coming from my core.

'The mana is already entering my core.'

'Now, for the last piece.'

Seeing the colorless liquid contained in the bottle, I gulped it in one go as well.

/PISS/

Revealing a smoke coming from my core….

"Hick!"

Just like that hiccupping started….

'This is going to be annoying….'

That was the only thought in my mind before tears of bodily reactions started dropping out of my eyes….
