Acnologia shook his head at the group's dumbfounded expressions: "You guys have absolutely no idea how to develop your abilities."
Natsu's eyes lit up, and he couldn't help but ask, "Development ability? How do we develop it?"
"By the way, you said you'd help me train, but you haven't kept your promise."
Acunorokia said matter-of-factly, "That was a long time ago, it's long expired."
"How can this be?"
Seeing Natsu's furious reaction, he smiled and said, "However, I can give you a few pointers."
"The most important factor in a flame is its temperature!"
Natsu couldn't help but say, "Of course I know that. As long as the magic power is strong enough, the temperature of the flames will also increase."
Acnologia had previously said that he could turn his emotions into flames, and it turned out to be true in battle; the angrier he got, the stronger the flames became.
Acnologia thought for a moment and said, "Try compressing the flames."
Natsu asked in confusion, "Compression?"
Acnologia nodded slightly, extended his right hand, and a ball of black flame emerged. His left hand continuously generated flames, which infinitely converged towards the ball of flame in his right hand.
"If you disperse it with a flame, the temperature will naturally drop; if you concentrate it, the temperature will naturally rise."
"It just needs to be controlled well to avoid an explosion."
Amidst everyone's curious gazes, the black flames gathered and compressed infinitely, and soon, space distorted, and that point of blackness produced a dazzling, extreme light.
If they dared to touch the initial black flames, the current extremely bright flames are so intense that just looking at them makes one feel suffocated, and their eyes are filled with a burning sensation.
As the flames grew hotter, everyone felt the air thin and had difficulty breathing. Some plastic items even started to burn without being touched, followed by wooden tables.
Apart from Natsu, the others couldn't take it anymore and retreated far away.
The terrifying temperature was unprecedented, so terrifying that it was suffocating. Let alone touching it, even getting close to it felt like they would dehydrate and die.
"This temperature..."
Gray was utterly shocked, staring at that extreme temperature. At this moment, he couldn't even use ice magic, no matter how fancy his spells were.
Acnologia, holding a black flame in his hand, looked at Natsu, whose face was filled with disbelief, and said with a smile, "How about it, want to try some?"
Natsu nodded excitedly: "Of course!"
He couldn't wait to open his mouth and inhale, swallowing the extreme black flames like noodles.
In an instant, black flames erupted all over Natsu's body, and the terrifying heat turned his entire body bright red.
"Natsu, are you alright?"
Lucy and the others were extremely nervous. The black flames looked incredibly terrifying. Natsu swallowed them whole, not even worried about burning his stomach open.
At this moment, Natsu looked like a giant branding iron, his skin turning red, something that had never happened before when he swallowed any flames.
Acnologia cast a magical barrier to isolate the temperature and fire; if Natsu were to unleash it, the entire guild would be burned to ashes.
"It's so hot!"
Natsu looked at the flames on his fist with immense excitement. At this moment, he felt an unprecedented power, as if his own flames could burn everything.
His dragon-slaying magic can transform the flames he devours into his own energy; the stronger the flames, the greater the energy, and the more satiated he feels.
At this point, he felt extremely full and would not feel hungry for the next two or three days.
Is this the flame of Acnologia?
Gray couldn't help but say, "It's so hot! Natsu, put the flames back!"
Natsu laughed triumphantly: "No way, Gray, I'm stronger than you now!"
He has so much energy right now, it's absolutely amazing! He feels like he could even take on Gildarts, let alone Gray.
He imitated Acnologia's earlier actions, gathering flames from his entire body into his palm. As the flames converged, the temperature rose rapidly.
Natsu stared at the bright flame in his palm, his heart pounding, and exclaimed excitedly, "It really works! Now I'm invincible!"
He felt that as long as he condensed and compressed enough flames, there was nothing in the world that he couldn't burn through.
Gray looked at Acnologia and asked eagerly, "Then how do I develop my abilities?"
His best friend Natsu suddenly became stronger, how could he stand still? This would be worse than killing him.
Acnologia sat back in his chair and pondered, saying, "The strength of ice itself also depends on its temperature. Theoretically, the lowest temperature is 273.15 degrees Celsius, which can freeze all matter, not even light can escape, meaning it can freeze spacetime."
"Freeze time and space?"
Everyone was shocked. Was this what they thought it meant?
Acnologia nodded: "I'm not sure, Gray can try to get there later."
After all, this is a magical world. The temperature limits of another world may not apply here; it might even reach minus 3400 degrees Celsius.
"Temperature..."
Gray hesitated. He had been focusing on the design, but today he was terrified by Acnologia's extremely hot flames. At that temperature, his ice couldn't even get close.
His design is already quite good; perhaps he should really work on improving the temperature control in the future…
He remembered that when he first learned the Ice Shaping Magic, Ulu made him take off his clothes and stand in the snow to experience the low temperature.
Marcus leaned closer: "Acnologia, come and see my magic. I am a sand magic user. What should I do?"
"Look at me, don't you know the first-come, first-served rule? I was here first."
"Go away. Your magic can only blow smoke rings. What kind of guidance do you need? Go home and smoke more cigarettes."
Seeing that Natsu and Gray's magic was progressing in the right direction, the others couldn't sit still any longer. They crowded around, forming a large circle, all clamoring to get guidance on their own magic.
What if I am the chosen one, but I just haven't realized it yet?
...
It wasn't until dawn that Acunorokia finally escaped the crowd. He took a sip of water to moisten his throat and then collapsed onto the sofa, exhausted.
Eileen sat down next to him, massaged his shoulders, and laughed, "You're quite patient, giving pointers to everyone."
"We've already discussed it, so we can't show favoritism."
Acunorokia swore he would never talk about such useless things again.
They all fantasize that they are the protagonist, holding a girl in their arms and dominating the battlefield?
Stop dreaming, I'm the main character, okay?
With him in the guild, they're guaranteed to win against any enemy. There's no point in these people leveling up their magic; they can just obediently serve as the background for his show-off.
