The Extra Can't be A Hero

Chapter 293: Training from Hell (1)

The next day.

Amon and Yue dragged a number of unfortunate souls into Yue's mirror dimension, a sealed inner world that reflected reality only in shape.

Among those taken was the budget Fantasy Couple, Leon and Ellahan, along with several of the Solaris House's highest authorities.

Leon's parents, Lucas and Aluria, stood among them, as did multiple Solaris Commanders and even the Solaris Lord himself, his presence heavy with restrained authority.

They were not alone.

Those aligned with Amon and Yue, figures who stood at the very apex of their respective paths, were gathered as well. The Sword Saint, a man who had once borne the title of the most powerful mortal on the planet, was there.

So too was Yugor Elune, the former head of House Elune, whose name alone still carried political and arcane weight.

At the centre of the magic stood Jex Amaris, the Archmagister of the Realm, his gaze sharp as he took in the distorted laws of the dimension.

Yet the summons did not stop with the old guard.

The younger generation of Eldorin was present as well; many of them recalled it prematurely, from what should have been a well-earned respite.

Not a single voice rose in protest.

Word of the Demon Prince's invasion had already reached them, and none could pretend ignorance or cling to comfort any longer. They understood that the era of spectators had ended. Thus, upon returning to Solfea, there was no time to regroup or rest.

Space folded, mirrors fractured reality, and one by one they were drawn into Yue's inner world, where reflection and truth blurred… and they were greeted by the magnitude of it all.

"Whoa, what is this?"

"Is this Yue's inner world? Isn't this another planet entirely?"

"Tch, shouldn't she take the Archmagister title? What am I holding it for?"

There were voices of awe, and disdain… but they were all universally in shock at what they'd just witnessed.

Yue's inner world held a colosseum that existed outside the tyranny of ordinary space, folded into a hidden dimension that brushed against reality only when summoned.

From the outside, it could not be perceived as a structure at all—only as a distortion, a hollowed-out absence where laws bent inward, as though the universe itself had been scooped away to make room for something greater.

Within the arena, the scene unfolded like a miniature world, vast enough that horizons curved gently, and distant structures vanished into an atmospheric haze. The floor alone spanned continents in scale, layered with shifting biomes of obsidian plains, crystalline deserts, liquid-starlight seas, and floating landmasses drifting like tectonic thoughts.

Gravity was not fixed; it obeyed the will of the arena, reorienting itself so that no god could escape battle simply by fleeing upward or downward.

Distance held no meaning here.

It was a place of distortion, a world not bound by the material plane, and a place of infinite possibilities.

Which was why Yue had created it.

Yue twisted the very backdrop of the mirror dimension, and the world behind her collapsed into a churning sea of flames. The pristine white of her hair darkened at the roots as sleek, curved horns tore free from her scalp, radiating an oppressive, infernal authority.

Despite the hellscape she had summoned, she wore a deceptively playful smile, one that clashed violently with the terror of her presence. Tilting her head, Yue stuck out her tongue in open mockery before declaring:

"Everyone, welcome to Hell!"

"Hah, Yue…"

Amon appeared behind her and literally slapped the horns out of her head. She rubbed the spot where Amon had hit her as tears welled up in her eyes.

"H-Hey, domestic violence?!"

"Hah… Stop scaring them."

Amon sighed and ignored Yue's grumbling. He looked at the array of talents he'd gathered here today and gave himself a satisfied nod. Even if they scoured the entire Hyades Republic, there were few who could match the elites present.

And after he was done with them… they could conquer the world on their own.

"I'm sure everyone is aware of why we're here today."

Amon's voice was loud, but it wasn't overpowering. It didn't have to be, since everyone present didn't dare breathe a word.

"The Demon Empire grows with every passing moment and… the return of the Titans is imminent."

"..."

Everyone heard about the Titans from Amon and Yue prior to entering the realm. Which was why they knew the urgency of the matter.

"As we are now, we are powerless to protect ourselves from the invasion of the Demons, let alone the Titans. And the fact that these two calamities are upon us simultaneously… Humanity is bound to fall."

"..."

"That is… unless we grow stronger!"

Amon clenched his fist and declared firmly.

"And so, Yue and I will train you. Not only to become powerful enough to fight against the Demon Empire, but the Titans too!"

And thus, Amon spread his arms… and the world answered.

Reality groaned as the landscape fractured, giving birth to dozens of cavernous gateways, each one exuding a vastly different mana signature.

They did not simply appear; they asserted themselves, forcing space to accommodate their existence. No two caves were alike, each governed by its own internal rules and trials.

Some caverns were embodiments of natural law. Within them, the laws of fire, water, wind, earth, and even pure arcane force were laid bare, no longer abstract principles but tangible, hostile presences.

Flames judged intruders, tides tested resolve, and raw mana lashed out with indiscriminate will.

Others were living battlegrounds—vast subterranean arenas crawling with thousands of bound spirits.

These entities were no mere echoes; they were powerful enough to warp the terrain itself, reshaping stone, atmosphere, and gravity through sheer presence and conflict. To survive within such caves was to endure an unending clash of wills. There were even some caves with Greater Demons that Amon and Yue had captured through their long years as Demon Hunters.

And then, there were the caves that radiated something far more unsettling.

They carried Amon's essence.

Within them stood doppelgangers—reflections of Amon that had inherited fragments of his power, his instincts, and his merciless precision.

Each was a trial of confrontation, forcing challengers to face not only overwhelming strength, but the terrifying clarity of Amon's own methods. The caves varied in depth and difficulty, meticulously layered to match the capabilities of those drawn into this training facility.

From survivable trials meant to hone foundations, to near-lethal crucibles designed to break and rebuild the strong, every path offered growth… provided the participant endured long enough to claim it.

"We only have a month to get you as strong as possible. Everything that you need will be provided for you. Yue and I will be supervising all of your trainings, so feel free to reach out to us if you need assistance."

Amon spoke with authority, and even those who mentored him in the past, legends like Alrock and Carmen, didn't dare to talk back.

Currently, Amon was the world's most powerful man.

They had witnessed it first-hand.

How helpless they were against the Demon Prince. How they had to rely on a junior, who was decades younger than themselves, to repel the otherworldly threat.

And they didn't want to feel that way again.

"Grandpa Alrock, Commander Carmen, Commander Gallahad, Sir Lucas. Yue has prepared a specialised course for you guys."

Amon first addressed the upper ranks of the Solaris House. They were first surprised that it was Yue, not Amon, who had prepared their training course, but they weren't able to get any answers from Amon.

"I'm also not sure what she has planned. But she told me it is the fastest way for you to improve your strength. Will you trust us?"

Although Amon didn't know what Yue had planned, he had utmost trust in her capabilities. If Yue said she had a way to enhance the Solaris, the executives might, then it must be true. After all, she was the one who helped him balance out the solar mana within his body.

"Understood, then we'll do that."

"Take care, Leon."

The Solaris executives said their goodbyes and followed Yue into an unassuming cave. However, the moment they entered, their presences vanished entirely, as if they had been swallowed whole by the dimension itself.

With Yue and the Solaris executives gone, Amon looked at the rest of those gathered here and handed out scrolls customised to each one of them.

"Follow the instructions on the scrolls. All the caves here are free to use, and we've prepared a customised path for each of you. If you follow them well, you will reach a level you've never felt before. But, if you don't wish to follow these instructions, that's fine too. Use the facilities as much as you want."

Although Amon wished for all of them to get stronger, he didn't wish to force any of them. If they didn't want to train hard according to his plans, then there was no point in trying too hard. So Amon didn't really care if they followed his instructions or not.

Well… except for one person.

"Leon, come with me."

"Y-Yes, sir!"

Amon sauntered casually toward the central cave, the one that embodied the Law of Fire.

Even from a distance, it pulsed like a caged star, its entrance breathing heat as though the sun itself had been sealed within stone. The moment the pair crossed the threshold, sweat drenched them from head to toe, the air thick and oppressive, every breath scalding their lungs.

The cavern walls were carved with ancient runes, each one blazing faintly as if awakened by their presence. These sigils did more than decorate the stone—they enforced the law within.

Fire was absolute here, sovereign and unquestioned. Merely stepping inside caused Leon's solar mana to resonate violently, surging and refining itself in response, while even Amon could feel the ambient authority pressing against his core.

It was, without question, the most ideal crucible for a Solaris to temper their power.

But that was not the reason Amon had brought Leon here…

"Reminds me of old times."

"Hmmm?"

"No, remember? I used to be your squire. And you would train me every day. This just brings back memories."

"Ah, that's right."

Leon brought up a story from yesteryear, and Amon chuckled fondly.

"And look at us now."

"Haha, and look at us now."

One was widely considered the strongest in the world; the other was the Hero who had inherited the Holy Sword and was on his way to greatness.

"So, how are we going to train? Like the good old days?"

"Not quite."

While sparring with Leon and gradually increasing his strength was a good method, Amon knew of a far better one.

"Seniors, how long are you going to remain silent in that sword? I can practically hear you jumping for joy."

[... Wow, you can even sense our emotions?]

[As expected of the man I chose as my equal… It's a pity you weren't born in my era.]

Two voices echoed directly within Amon and Leon's minds, bypassing sound and space alike. One was booming and hearty, carrying the weight of unshakable conviction, while the other was silken and indifferent, smooth enough to be unsettling.

A heartbeat later, smoke began to coil from the Holy Sword at Leon's side. The vapour thickened, twisted, and then took form, giving rise to two apparitions that materialised behind Leon as though they had always been there, merely waiting to be noticed.

And well… Amon recognised them in a heartbeat.

"I greet the Solaris Founder and the Saint."

Truly… there was no better pairing to teach Leon.
