Two days had already passed, and each day, Bran and I had our respective schedules of training laid out by our mentor Gladius. The interrogation with us for what happened in the dungeon was avoided as our mentor took care of it with the higher officials, we still did answer a few questions from the people from the adventurer's guild.
Now that the dungeon problem was resolved, I was wondering about a way to quickly develop my physique first, as my mentor here had already noticed my scrawny body and ordered me to follow a physical building schedule for a month with the freshmen students who had recently entered the academy.
It seems like I should run a hundred times a day, and without doing that, I can't enter the gym. Nice choice of training if I say so myself.
Well, to be honest, Master Gladius had given Lucas the training schedule two years ago when he and Bran became his apprentices, but Lucas was not only weak; he was a lazy idiot who only admired the strong people's acts. From my memories, Lucas tried his best to do the exercises, but along the way, while seeing his juniors surpassing him day by day, he just lost his will to fight again, even when his brother Bran continued to cheer him on.
I don't say I appreciate the way he did things with this weak body, and it was so idiotic of him to hold someone who trusts him a lot back. Heck, just remembering this stuff is pissing me off.
I must change everything about my current self. I must get stronger. I will get stronger.

[AUTHOR'S POV:]
"Isn't that funny!"
"Senior student Lucas, right?"
"With this body? Why even try?"
"He might as well be good as dead from training!"
Lucas Trident was running continuously in the ground outside the gym facility. The freshmen students who were passing by and training inside the gym were seeing the scrawny-looking student who kept on falling down as he completed at least a round, with their expressions filled with smiles and mockery.
Little did they know, the boy isn't the same one they had bullied before, and no one could've known that the boy had a soul of someone who has authority over the abyss itself.
With each mockery they did, they could never know, their death was hanging by a string.
Each time Lucas heard the mocking of people, his anger grew out, and even clenched his fists that practically pierced his skin, bleeding blood.
However, with every mockery, his desire to become strong got stronger and stronger. He cursed his current self and the body of Lucas here and now because of his true self as a strong Demon King who was stuck in a body of a human and a weak one at that, but even he did so, he never gave up.
A week had already passed, and just like always, Lucas ran till he passed out.
And still, he hadn't been able to complete one hundred runs around the ground. Word about him running day and night got out as the academy's professors came and tried to snap him out from his 'un-fruitful' training they thought he did.
Bran Trident and his mentor Gladius Ravenheart were the only people who never stopped him and never stopped supporting him while Gladius being strict with Lucas as hard as he could.
It was the last day of the week, and by the end of his thirty-fifth round, he was running without falling, and with the round of fiftieth, his speed increased, leaving the students and teachers who thought Lucas was miserable, stunned.
"This can't be?"
"Bleh. It's just a fluke!"
"A weak is always weak!"
However, their mockery didn't stop. By the next day, Lucas had completed his one hundred laps, which was already quite a feat according to his peers, and headed inside the Gym, working out on his body training regiment his mentor had assigned.
Even as the Demon King with more than a million years of experiences in fighting, he didn't change the training regiment planned for him by his mentor, as he thought his mentor had already considered everything Lucas's body needed to do.
So he started.
His expression was so calm that one couldn't associate with him. But in truth, Lucas was burning with anger; if he didn't have control over his mind, he would just devour the students there with the abyssal power he possessed.
Walking in, Lucas saw an unfamiliar instrument used to train the lower body, which in his life as a demon king he neither had to nor have to use. From the collection of memories Lucas had, this instrument was named as the Leg Press.
'Lowest rank.'
It was true.
He tried it with all his might; he even pushed his body to its end, but the result didn't change, and he still didn't want to give up. All he did was complete his one hundred laps of running. In a way, as he wiped the sweat from his forehead, it was good that he was able to move ahead.
With the advancement exams being conducted two months from now, he had no choice but to train his physique and attend the battle courses soon. With that desperation, he kept on trying.
After that, he moved on to the instrument to strengthen his muscles, the dumbbells.
He lied down as he caught the iron bar, which was tightened with two big weights, fixed at its two ends, as he tried to lift it.
However, with just not even lifting the weight halfway, Lucas kept on dropping the instrument with his hands, which had become numb.
Seeing that, one of the junior students in the room spoke with a grin.
"Yo, look! the Zero is self-training?"
That human just survived his death thanks to Lucas's control over his anger. Without hearing the fool, Lucas kept on with his training.
The other children who heard the words opened their mouths. Then, as they looked into each other's eyes, they burst out laughing.
"Uh-huh, right. What will change just because he is working hard from now on?"
"He will die from training for sure!"
"I think he faked his hundred laps!"
"How the hell did you get into this academy with that strength?"
Anger bustling from Lucas's heart, a sudden chill enveloped the room. Lucas's eyes had become flaming red as the air he was breathing was as cold as the ice.
"Hey man. What's this?"
"This is still summer right? I'm feeling pretty cold now!"
"Soo~ Colld"
Lucas's anger went out of control, changing all the elements in the atmosphere around him to the absolute domain with killing intent, making the others feel the coldness of just a fraction of the Demon King's wrath.
Well, it's not like it would change anything. The students just left, like they were bored, leaving Lucas all alone while he concentrated on his training.
As this marked the day one of completing all his workouts, a month had passed.
He ran more than a hundred laps, took one hundred push-ups, one hundred squats, and one hundred sit-ups, every single day for a month and swore to himself he would do that even after that month ends.
He ran laps so early in the morning that practically no one except Bran would know when he heads outside for training. He trained alone at the Gym when no one was present. In the meantime after he trained in the Gym, he would swing his sword which was formed by his Black-cube of dark element.
Bran and Gladius made sure no one bothered Lucas while he is working out, However, no one knew or was able to witness Lucas's growth and his development, not even his own Mentor.
With only one month of intense and rigorous training, Bran, being Lucas's roommate, was able to witness Lucas's transformation.
As, Lucas had shredded his scrawny cocoon and became a butterfly.
