Hellish Training

Demonic power, it's the power used by devils, the complete opposite of holy power used by angels. All Devils ranging from High-Class to Low-Class can use this form of power, letting them both create and control different supernatural phenomena for different forms of combat.

Some unique demonic powers are inherited among the different 72 Pillars and the Extra Demons, which no other devils outside their respective clan can use. One of these unique demonic powers is the Power of Destruction, which Lucius inherited from his mother's clan.

In order to use demonic power, it has been described that a devil must first acquire the power of imagination, the power to create, and good sense; however, the main prerequisite for all this is, is that it requires a certain amount of demonic power.

One can even say that the amount of demonic power equals that of the potential strength, a devil can gain in his life. A good example of this are the super devils or transcendental devils such as Rizevim Livan Lucifer, Sirzechs Gremory, and Ajuka Astaroth, all of whom were considered irregular devils born with demonic powers exceeding that of the original Four Great Satan, with their powers reaching and surpassing most of the Gods of other mythological factions. 

This is also the reason why Lucius was frustrated after most of his demonic power was sealed since with a limited amount he can use, the strength he could use is also limited. It's far from his past strength which he could easily blast an island into oblivion.

.....

Fiore, deep inside East Forest near Magnolia, Lucius was running. Sweats dripped down from his whole body as he run.

After leaving the guildhall, he got in this place to train. His training mainly focused on physical strength. First, he applied gravity magic on his body and started running. The gravity on him was about 15× that of earth's gravity.

As he ran, he also trained in using his PoD by shooting some moving targets, which are the small animals he passed by. He has been running for about 2 hours now and due to the gravity magic on him, the effects were as if he ran for days without rest.

But he persevered through it, his motivation being quickly gaining back his strength to find a way back home.

"Huff...huff...! Haa...! My body could still take more gravity, let's raise it."

The gravity was raised to 30× which caused the sounds of creaking bones. But Lucius continued running on with determination.

Time passed by, but Lucius didn't notice how much time. He just ran without rest and tried to push his body's limits. He learned it from his cousin, Sairaorg Bael.

As someone born with low demonic power and without their bloodline power, Sairaorg led a miserable life. He and his mother were cast out of the Bael clan.

Lucius frequently visited this cousin of his and learned how the latter trained his body to the limits. Since Sairaorg didn't have enough demonic power, he focused on his body. Pushing to his limits and then surpassing them to become stronger.

That's what Lucius aimed for his current predicament. He wanted to surpass his body's current limits. Since he didn't train his body previously and it's also his only way for now to increase his demonic power, he persevered.

.....

"Huff...huff...huff...!"

After some more time, Lucius was dripped with sweat that it looked like he swam on water. His breathing was heavy and his muscles are screaming for him to stop. He didn't stop though and continued on his run before arriving at a big tree with a pathway in front.

Lucius felt his vision was getting blurry until his body finally couldn't take it and dropped in front of the big tree. His eyelids became heavy but before he fully closed his eyes, he saw a blurry view of a door and someone exiting it. After that, he collapsed due to severe exhaustion.

The one he saw exiting was a slim and tall elderly woman with pink hair, tied in a bun on the back of her head by two large pins with crescent moon-shaped edges, and with two bangs of hair left framing her face. She has reddish eyes, and a beauty mark located below her mouth, on the left side of her face.

Her attire consists of a dark green blouse with a tie around the collar, paired with a long matching skirt and simple shoes. Over this, she sports a crimson-colored cape, with a wide collar decorated by massive Dragon horn-like decorations protruding outwards, and edges adorned by white, arch-like motifs.

She frowned after seeing Lucius, collapsed on the ground, "And who is this human kid? I hate humans!"

Opposite to what she's saying, Porlyusica easily carried Lucius inside her house. She then laid him on a bed and removed his shirt then saw the fairy tail guild mark on his left pectoral.

"Che, so he's one of those old man's..." She muttered as she grabbed a nearby towel and wiped the sweat off Lucius.

"Just what did this kid do? His muscles are overstrained and he seemed to exhaust his magic power."

Following that, Porlyusica brewed medicine using different plant extracts. Then she put the medicine in a bowl and forcefully fed it to Lucius who was still unconscious.

After that, she got back to whatever she's doing previously before finding Lucius.

.....

Sometime later, Lucius slowly woke up. He sat with some difficulty and glanced at the place he was in. It is decorated rather sparsely, without too much furniture.

The little furniture there is consists of a bed, a working desk, several stumps, and numerous crates and barrels. There is also a large collection of books placed on shelves which were dug into the trunk of the tree.

Lucius noticed Porlyusica sitting in front of her working desk. He spoke up, "Um Thank you for tending my body after I collapsed."

Porlyusica turned around and frowned, "It seems you're okay now, then leave my house now. I hate humans!"

Lucius was taken aback but just smiled and stood up. He then started walking towards the door but before he left, he once again said thank you.

"I'm grateful for this, please find me in fairy-tail if you need help. Please tell them my name, Lucius so I would know if you ever need my help."

"Ha?! Why would I need help from a kid, like you? Hmph, just leave, human!"

Lucius smiled wryly and excited the house with his sore body. 'I'm not a human though haha~' he chuckled in his mind and walked away.

After getting away from the house, Lucius noticed the sun is starting to set. He started his training in the morning and added how many hours he slept after exhaustion, it seems about right.

"Looks like I won't be continuing my run for today, I'll practice my control tonight." He muttered then used teleportation to arrive just on the outskirts of Eastern Forest. He then walked the rest of the way towards the guildhall.

....

Entering the hall, Lucius was net with a flying chair with he easily grabbed. He then looked around and saw how everyone was in a brawl which made him dumbfounded.

'What the-?!' Getting out of his stupor, Lucius went towards the bar where Makarov sat as he weaved through while avoiding being hit.

"Oh Lucius, your quest has been confirmed done. Here's your reward." Makarov handed a bag of money to Lucius.

"Eh? Thanks..." Lucius said, "But what happened here?"

Makarov glanced around and grinned, "Get used to it, it's the usual sight here. Kahaha!"

Lucius smiled wryly and decided to walk off and head towards his temporary room in the guild building.

From there he started his control training over his demonic power.
