Time is flying and 11 years soon passed.
The first stage of dragon slayer training was actually the dragon slowly injecting their magic powers into the learner.
Over time, a Dragon Seed would form into the learner, transforming their organs to be similar to that of a dragon.
After learning the basics for a while, Nicolas learned that diamond dragon slayer magic was actually the most advanced version of rock dragon slayer magic and Carbos was the king of rock dragons.
Carbos could eat rocks like the other rock dragons to sustain himself but diamonds and other gemstones were apparently a delicacy for rock dragons.
After Nicolas's dragon seed grew sufficiently, he also became able to eat rocks and gemstones so food problems disappeared altogether.
On top of magic training, he also did heavy body training since diamond dragon slayer magic heavily relied on close combat and body toughness.
From time to time, Carbos also made him fight magical creatures of various strength to hone his combat skills.
Although at first, Nicolas was scared to fight and lost multiple times, he eventually overcame his fear of getting hurt and even began to enjoy the process of getting stronger after fighting a strong opponent.
Diamond dragon slaying magic gave him unparalleled defense and endurance but the only obvious flaw he found was that he couldn't create diamonds for a free money glitch. He could only transform his body to diamond and modify its form and shape to a certain extent. As soon as the diamonds were separated from his body, they dissipated after a few seconds but he was still able to use them to attack.
But even that flaw wasn't much of a problem for Nicolas because the cave where the both of them were living in was actually a gemstone mine created by Carbos by eating through the rocks of the mountain.
The depths of the cave was actually filled with rare gems so if he ever needed money, He could just take some gems and exchange it. Although during the last eleven years, Nicolas never had any human contact since he spent most of his time deep in a cave or fighting monsters so he never needed money.
At first, Nicolas was very reluctant to eat gems because of greed and stinginess but after trying, he actually got somewhat addicted. Although he couldn't describe the taste into words, it gave a feeling of eating a high-class food. This was due to the fact that his taste buds already transformed into that of a dragon giving him a different sense of taste from that of normal humans.
On top of that, Carbos also taught him how to read and write. Although Nicolas was surprised that a dragon actually know human writing systems, he didn't bother asking because there's no point to knowing that anyway.
After living together for a while, Nicolas also learned that Carbos was actually a laid back guy who loved joking around. The solemn tone he was using when they first met was actually because he wanted to make a good first impression and did what he thought would look cool.
For eleven years, the two of them lived peacefully without any problems but around the time Nicolas turned 14, he suddenly became able to sprout dragon wings on his back.
…..
Year X376
'Damn it, I didn't expect the dragonification to progress this fast.' Nicolas thought to himself.
'The silver lining is that I could still make the wings disappear for now but I have to slow down my training from now on.'
Nicolas always had a plan of finding a dragon lacrima to implant onto himself in order to mitigate the dragon seed but he failed to take in account the fact that he became strong too fast making the dragon seed's growth faster.
He didn't want Carbos to enter his body to create antibodies. Carbos might not even know that technique and Nicolas also knew that if Carbos entered his body, only death would wait for him in the end.
Nicolas considered Carbos close family because what kind of guy wouldn't get attached to someone who lived and took care of them for years.
He didn't consider him as a parent because he already had 2 birth parents who loved him in this life and two more parents during his previous one so adding another one would just be silly at this point.
…
Seeing Nicolas sprouting dragon wings startled Carbos because he wasn't aware that dragon slayer magic had side effects like that.
After that, Carbos left for a week.
As he came back, Carbos told Nicolas that they would be leaving their nest and explained that he would be learning from another person from now.
Nicolas was shocked hearing that and immediately asked Carbos if he would leave him but Carbos confirmed that he wouldn't so Nicolas didn't have any problems with moving out.
The two of them then left flying alongside each other because Nicolas wanted to test his newly found flight capabilities.
…..
After a while, they finally landed in a forest. As he looked, Nicolas could see 5 dragons with vaguely familiar features and a blonde woman waiting for them.
'Huh?! Aren't those Natsu and the other's dragons and Anna Heartfilia.'
After 14 years in this world, Nicolas was finally able determine the timeline he was currently in. He also quickly deduced that he would be part of the eclipse team.
'Well, that's a pleasant surprise but wouldn't that mean that Carbos was planning to enter my body?'
'Fuck, I have to ask Carbos to find me a dragon lacrima fast. I'll just play dumb if he asks me about how I know about that.'
Anna who was approaching suddenly began to introduce herself as his new teacher to which he responded with a polite introduction of his own.
Anna then told him to follow her and began to introduce him to the dragons present.
He already knew the dragon's name but still politely greeted them one by one.
After following Anna for a little bit, they finally arrived to a nearby shack. And as they entered the shack, he saw five kids. The two older kids being Natsu and Gajeel were quarreling while two other boys Sting and Rogue watching intently and Wendy, the only girl in the group sitting quietly on the side.
Anna then clapped her hands a few times to get their attention since they were too preoccupied with what they were doing and as she finally got their attention, she introduced Nicolas.
Anna then left the room to let them mingle with each other and as soon as she left, Natsu immediately approached Nicolas asking him if he was a dragon slayer too.
Nicolas casually responded with a yes prompting Natsu to pick a fight with him saying that they should compare who's stronger.
'Well, that's Natsu for you.' Nicolas thought while also taking a glance at Gajeel and the others.
'Time to teach them the pecking order, I guess.'
"Alright then, let's get out." Nicolas said.
As Natsu and Nicolas made their way out, the other kids followed them too to watch the upcoming "fight".
Nicolas immediately taunted:
"Alright, you five come together all at once. It'd take too long if we did it one by one."
Hearing Nicolas say that made all of the boys very angry and told him to not underestimate them.
To which Nicolas responded "It will be alright, after all….you're weak." While smiling slightly.
'Nice, I was finally that famous quote in real life.' Nicolas thought to himself not even caring about the enraged Natsu and Gajeel rushing towards him.
Nicolas just stood in place, receiving their attacks to gauge their power for a bit because he didn't want to accidentally hurt them.
Nicolas showed a disappointed face since their attacks didn't even remotely hurt.
Natsu and Gajeel who saw that their attack weren't effective at all tried to use dragon slayer magic to fight but Nicolas rushed towards them and hit them both on the head, knocking both of them out because he got bored of this "fight".
Nicolas then looked at Wendy, Sting and Rogue who were terrified after seeing Nicolas knock Natsu and Gajeel in one punch and said:
"Do any of you want to fight too?"
The three of them shook their head vigorously signaling that they had no intention to fight.
Nicolas then said in slightly loud voice:
"From now on, I'll be your boss and you guys will be my minions."
