Mana core, a crystal made of concentration pure mana. Although it is called a crystal it doesn't have any form. It is located in the heart in an intangible shape. It is real yet also not real.

In Firuman, mana core is a very important source of power for the survival of civilian society against the monsters. Yet not everyone could awaken mana core. In the human race, everyone has a chance to form the mana core as long as they have enough talent in perceiving mana.

​​

For the trained children such as nobles, they could even form their mana core early starting from the age of ten. The untrained child needs to have a great talent to form it naturally which usually happens at the age of 13-15.

This range of age is also the age where a human teenager could easily form their mana core manually as their body is more attuned with the mana.

Angus managed to form the mana core at the age of 11 which is already an incredible feat. Only a genius or prodigy could form mana core below the age of 13.

Forming mana core is not easy, it is a tedious and delicate work that needs a full concentration for every step according to each technique instruction.

Each technique is different and like Angus research before, each technique is tailored to a person, race, or someone with a unique body. This also increases the difficulty for other people using the existing technique as it is not compatible with their body.

Angus creates his technique that is suitable for his own body. This technique led him to form his mana core from the get-go without the need to stop.

Furthermore, he has heritage chi that acts as the source power for him to create his mana core. Using all of this, he finally creates an ultimate mana core according to his criteria that is complement his body.

However, this feat is not without repercussion. After Angus formed his mana core, he needed to take an absence for a few days to let his mind and body rest.

Although the new mana core is already working to alleviate his body fatigue, he still feels like taking a rest for his body to completely adapt to the new mana core.

'Haa… This is bliss. Not doing anything for a while and sleeping in my comfy bed.' Thought Angus inwardly before looking at his status panel.

Host: Angus Victory

Age: 11 Years Old

MP: 138/138

Heritage chi: ???

Strength: 20

Dexterity: 20

Intelligence: 40

Vitality: 36

Soul Point: 88

After forming his mana core, his mana immediately increases a lot like a burst of the dam. Normally, this kind of increase will make him harder to control his mana. However, his new mana core could easily solve this problem.

Angus feels like the mana core is a new organ that is always working without the need for him to control it. If before Angus needed to be conscious to manually control his mana in the body, now he feels like there is a machine or tools that help him control it.

The difference is like sky and earth, if before he felt like running on foot, now he feels like riding a bike or motorcycle. He speculated when his mana core grade becomes higher it may feel like riding a car or supercar.

Besides the increase in his mana limit, his strength and dexterity is not grey out and could be increased again. Without wasting any moment, he increases both of them by one and consumes 80 Soul Points in total.

He immediately feels discomfort in his body muscle. His body feels like being pricked by a small needle but it is painless only leaving him a sense of discomfort.

It is more like having a small cramp all over his body. Angus also feels his body is moving or reacting faster than usual as the side effect of increasing his dexterity.

'*Sigh* I will never get used to this. It seems the side effect is becoming worse as the status is higher. Well, it will be another rough month.' thought Angus inwardly.

Then, he looked at the manual battle selection and looked at his opponent list. Angus found that finally the previous opponent below the 60% winning chance improved by one or two percent.

The harder the opponent inside the manual battle will give him more soul points to improve his stat further. Still, he didn't rush and try to fight them, he will wait until it at least reaches the 70% winning chance mark before challenging them.

Although he feels this is only a small improvement, it is still better than before when he didn't improve at all. Satisfied with his improvement, Angus decides to enjoy his comfy bed and sleep. Before he could sleep, *Knock* *Knock* someone knocking on his door.

'Haa.. Just when I want a nice sleep. Whatever, I will ignore it. Besides, no one ever bothered me before. So, probably someone going to the wrong room.' Thought Angus while pulling his comfy blanket.

However, the knocking continued and turned into the sound of the door being hit. If not the door is made of special wood and enchanted, it will be destroyed already.

"ANGUS.. I know you are in there. Open the door!!" shouted a girl with an angry tone.

'Haa… That's Jayna. Just what the hell she wants.' Thought Angus while reluctantly getting out of the bed.

"Angus, Open the doo.." before Jayna finished his sentence Angus opened the door suddenly.

But, Jayna didn't expect this and lost her balance while trying to banging the door. Unfortunately, her hand hit Angus face at the right moment.

Normally, Angus could easily avoid this using his superb body control but his body still fatigued from forming the mana core combined with the increase of his strength and dexterity.

After getting hit Angus immediately fell on the floor, looking at what she did and Jayna panicked. She also didn't expect this as this is the first time Angus gets hit by her.

"A-Angus… A-Are you okay?" asked Jayna worriedly.

Looking at the sleepwear Angus is wearing, she immediately thinks that Angus is truly sick and not pretending like he is usually done.

While Angus is feeling hurt in his face after getting hit by the violent princess, Jayna herself didn't know what to do as she never encountered such a situation. She feels wrong but she also never tends people to injury despite often injuring them.

"Urgh… That hurt. Why did you suddenly hit me?" said Angus with a droopy tone as his body was still limping.

"E-Err… I-I just want to give you the copy note of today and yesterday's lesson. I-I am sorry." replied Jayna, shuttering and giving the paper note.

"Haa… Don't worry about it. it's just a small bump on my face. Okay, thank you for your note." While Angus moved wobbly to get out of the room.

'Damn.. my body feels weak right now.' thought Angus while trying to move his body.

"E-Eh… Angus where are you going?" asked Jayna in a concerned tone.

"Ahh.. I just want to get some ointment for my bum. Don't worry about it." replied Angus

"No.. you stay here. You are sick. You are not supposed to move. Here, I have the ointment." said Jayna while she was given the ointment from her space storage device.

Then, without waiting for Angus to reply she went away from the spot as she didn't feel comfortable in this situation. She also feels guilty for hitting Angus face.

'What a weird girl? Does she on that time of period. None of it matters. Still, I didn't expect my body to be weakened by this much. I guess I need some rest before challenging the manual battle again.' Thought Angus while going inside his room again.

His Idle system only estimates the winning chance from Angus's overall capabilities in top form.

So, if Angus entering while in exhausted form and fight an opponent with a 70% winning chance it is more like suicide. After applying the ointment that Jayna gives, Angus goes back to sleep in his comfy bed.

Few days passed without any trouble. Now, Angus's body is fully healed and he went to the smithing area to meet with the old dwarf Balrug.

Since his body physical limit is increased by his mana core, he will continue his training to increase his training again. At first, he is reluctant to show that he is already forming his mana core to old dwarf Balrug, but he feels the old dwarf will find it sooner or later.

Beside the old dwarf is one of the few people who know his true power. So, for Angus, it doesn't matter whether he knows about it now or later.

Arriving at the empty smithing facility, "Crazy old man, Are you there?" shouted Angus.

After a while, Angus feels weird as there is no response from the Balrug like usual. Then, he decided to enter the smithing facility into the deeper area.
