The Demon King Who Was Supposed to Lose Ended Up Defeating the Targets, and Now the Heroine Has Been Sent as a Sacrifice - Chapter 28

Chapter 28: The Demon King Supposed to Lose, Levels Up During Battle

The battle between me and Arcyon was slowly reaching its conclusion.

‘The difference in our raw strength is showing. I’m stronger than you.’

“…Yeah, at this rate, I might lose.”

Arcyon’s attacks were heavy and fast.

Even though I was pouring nearly all my magical power into the fight, Arcyon still seemed to have plenty of energy left.

I’m currently close to level 3000, but Arcyon is likely even higher.

I have no idea how I can win.

‘To be honest, I underestimated you.’

“You think you’ve already won?”

‘No. This is a gesture of respect and an apology to a worthy opponent.’

Arcyon bowed slightly toward me.

‘I didn’t expect to struggle this much against you. You’re truly strong. I enjoyed this battle.’

“…Tch. Well, I had fun too. It’s been a long time since I fought someone who pushed me this hard. Not even the monsters in dungeons were as strong as you.”

This was how I truly felt.

Since my level had increased, I had fought several times during training with Elsia and the Demon King’s army.

But none of those battles required my full strength.

Sure, it feels good to completely dominate with overwhelming power, but sometimes, you just want to go all out.

In that sense, fighting Arcyon was genuinely enjoyable.

When I throw a punch with all my might, a human opponent would be obliterated. But Arcyon merely staggered back slightly, taking minimal damage.

Arcyon is definitely strong.

But at the same time, I can’t shake the feeling that it’s not unbeatable.

‘This is my mercy. If you surrender, I’ll end it quickly without making you suffer.’

“…Pfft.”

‘?’

“Haha, hahahaha!!!”

Arcyon, looking straight at me, tells me to surrender.

Sorry, but—

“Arcyon, you’re still underestimating me.”

‘…You don’t stand a chance. You’re out of magic power, aren’t you?’

“That’s true. But then I’ll just get more.”

Arcyon tilted its head.

‘How?’

“I’ll level up.”

When you level up, your magic power increases, along with your other physical stats.

But in reality, it’s not that simple. Arcyon seemed to understand my words, yet it still dismissed the idea.

‘It’s true that leveling up is probably your only option right now, but realistically, it’s impossible.’

“And why are you so sure?”

‘I’ve noticed you’ve been occasionally casting spells to take out wild monsters on the ground. But your level is already quite high, isn’t it?’

“…Yeah, that’s true.”

Naturally, the higher your level, the harder it becomes to level up.

‘Even if you’ve killed a dozen or so monsters during our fight, it won’t make much difference to your level. Unless you plan to slaughter your entire army on the ground for experience points, that is.’

“…I’m not that cruel.”

‘Exactly. You’re certainly strong, but you’re not a berserker who’ll do anything for more power.’

Arcyon’s observation was spot on.

But it was missing something crucial.

“But, you see, those who weren’t originally part of the Demon King’s army are a different story.”

‘? What do you mean?’

“Look down at the ground. Take a closer look at those moving around down there.”

Arcyon, still wary of me, glanced down at the ground.

‘Are those… undead?’

“Correct. They’re undead created by Elsia, my wife. They can even move under sunlight.”

It seems that Elsia had gathered the undead in a visible location for me.

I noticed this almost by accident.

While I was making sure my spells didn’t hit Elsia and the others on the ground, I noticed the undead moving in an unusual way.

I kept glancing at them during my fight with Arcyon, and I realized what was happening.

‘So what?’

“Those undead weren’t originally part of my army. They’re actually recycled from the people of the kingdom that we killed.”

‘…You can’t be serious.’

Arcyon’s eyes widened, but even though it looked alarmed, it still shook its head.

‘No, so what? Sure, killing that many might raise your level a bit, but not by much. You’re already at a high level, so it won’t make you significantly stronger.’

“What if I could reset my level—well, maybe not exactly reset—but start back at level 1 while keeping my current strength?”

‘…That’s impossible. There’s no way you could do that.’

“It’s actually possible.”

I pulled out the dungeon item that I always carry with me.

The same item that’s saved me time and again.

‘What’s that…?’

“A Rebirth Stone. It’s a magical item that allows you to change your race.”

‘!?’

“Now, the real fight begins.”

I cast a spell toward the ground and simultaneously used the Rebirth Stone.

The race I chose to transform into was the Archdemon.

This is a higher-tier race that only evolves from regular demons under specific conditions.

The fact that the Rebirth Stone lets me bypass all those conditions to become an Archdemon is an absurdly overpowered cheat item, even without overthinking it.

I transformed into an Archdemon, and my level reset to 1.

At that exact moment, the spell I cast reached the ground, obliterating the undead.

“Yes!! This is it!!”

An incredible surge of power coursed through my body, filling me with energy from deep within.

My magic power was restored, and my physical abilities were heightened.

Since the undead Elsia created included the thousands of residents we slaughtered in Avan, the number was in the tens of thousands.

Taking them out all at once shot my level up into the triple digits. It felt like I gained around 500 levels.

“Here I come, Arcyon!!”

‘Tch, even if your level went up a bit, there’s no way I’ll lose to you!!’

I closed the distance with Arcyon much faster than before.

‘What!?’

“My speed is now greater. Next, let’s see how my attack power compares to your defense!!”

I lunged at Arcyon, throwing a punch.

Where before it felt like hitting a solid iron wall, this time was different.

I managed to shatter Arcyon’s tough scales.

‘Ugh, you…!!’

“A breath attack? Bring it on!”

Arcyon unleashed a breath attack from its mouth—the same massive laser beam from before.

I faced it head-on, ready to take the full force without using any magic, relying solely on my body.

A little while ago, this would have scorched me completely.

But now, my level has increased by several hundred since then.

“Feels like a mild sunburn.”

‘What!?’

Arcyon was at an estimated level 3000, while I was now at level 3500.

A difference of just 500 might seem small, but in reality, it was a massive gap.

I’d seen enough.

With my current power, I could definitely take down Arcyon.

“Now it’s my turn. —Darkness Core.”

I gathered all my magic power and unleashed my most powerful spell.

This was a spell I had once created on a whim, and it ended up wiping out an entire dungeon.

It doesn’t emit radiation or anything, but the smoke that rises afterward looks like a mushroom cloud, so I gave it that name.

It’s my ultimate move.

With my current stats, even a holy dragon won’t stand a chance against it.

“Get blown away!!”

‘Guh, AAAAAAAAAAAAHHHHHHHH!!!!!!’

Arcyon was engulfed in the explosion and fell to the ground.

For most creatures, my ultimate move would leave nothing behind—not even a scrap of flesh—but it seemed Arcyon was still breathing.

Still, this was clearly my victory.

“Yes!!! Harem time, here I come!!!”

I shouted in triumph.

But I knew Arcyon was probably still alive, if only barely.

I needed to finish it off for good.

With that thought, I descended to where Arcyon had crashed, but what I saw nearly knocked me off my feet in shock.

There, where Arcyon had fallen, was a beautiful blonde girl, around thirteen or fourteen years old—about the same age as Misha.

Her eyes gleamed with a golden light, and she radiated a certain noble aura. At first glance, she could have been mistaken for a high-ranking noble’s daughter, but there was one detail that stood out.

Her slender, petite frame was contrasted by an unbelievably large chest.

And her thighs were thick and shapely.

These two features somehow existed in perfect harmony, making her large chest seem completely natural.

This blonde, well-endowed girl gazed at me with dreamy eyes.

“I’ve never met someone stronger than me before. I never imagined I could lose.”

That was the same voice I had heard directly in my mind earlier—the voice of Arcyon. 

Could it be that this beautiful girl is actually Arcyon?

No, it must be. I need to finish her off quickly.

“I’ve made up my mind.”

With those words, Arcyon stood up, looking determined.

I braced myself, thinking she was ready to fight again, prepared to respond at any moment.

But Arcyon said something completely unexpected.

“I want to have your baby ♡ Please, make me pregnant ♡”

“…”

In the heat of the battle, once again, I found myself in a ridiculous situation.
