The Reincarnate Became a Professor at the Academy

Flesh of the Demon God.

It was the spoils brought by Han Seojin, the God of Games, Victory, and Civilization.

Han Seojin, who bore the names of three gods, destroyed everything in the Demon Realm, prompting the Demon God to turn back time.

Perhaps it could have continued, but the Demon God first extended a hand of reconciliation.

Offering his flesh, asking for a truce.

Although it was true that he struck first, I accepted it.

I couldn't maintain the divine names I possessed forever.

Having used up Eternity, making the Demon God an enemy became troublesome.

For now, he wouldn't be able to invade. But even if I regained my peak, I could not defeat the Demon God.

However.

If I were to destroy all the civilizations of the Demon Realm, it would come to kill me no matter what.

It could be 3 years, or maybe 5 years.

There should be at least more than a year.

It was true that I was becoming stronger at an unprecedented pace here, but no matter how strong I got, I couldn't withstand the Demon God.

That's why I accepted that proposal.

Anyway.

The Demon God's flesh was incredibly difficult for me to use.

No matter how skilled I was, it was a material I had never handled before, and the body of a being with such a distant divine name was incredibly hard in itself.

'Extremely.'

Would it be possible to process it by wielding energy for decades?

It was impossible to process this physically.

To put it extremely, the flesh of the Demon God contains something several levels superior to energy, making it nearly impossible to inflict damage.

The efficiency wasn't great either.

So I thought.

A being that had reached transcendence.

What if I could process the soul with that?

'I've got a rough idea.'

How to process that.

The soul of a transcendent being.

By cutting down its realm, and processing it.

It was the most efficient method, but finding and killing such an existence was difficult.

But that evil spirit?

'I'm lucky.'

It met many conditions.

Ideally, it would be best if it became a transcendent being.

'The realm of a once-transcended soul.'

Even that alone was quite useful.

However, if it became a transcendent being, it might be a bit troublesome.

'Can I handle a transcendent being?'

Thinking about it, it was possible for now.

But I was worried about Shin Yura's life.

The strike of a transcendent and the strike of a supreme realm were on different levels.

If I was not careful, Shin Yura could die from the aftermath.

I dragged it far away, but in a split second, if it attacked Shin Yura?

'I don't want to think about it.'

So I had to kill it quickly.

Fortunately, our interests aligned.

That bastard wanted to kill me no matter what.

And I felt the same way.

I placed the shaft of the Wind God's Spear on my shoulder and extended my arm so that the tip of the Black Demon Sword pointed at him.

Whoosh.

Ashen flames bloomed on the Black Demon Sword.

-Can you handle it?

"Well. Whether I can handle it or not, it doesn't seem like the point."

I said with a smile.

"Anyway, you plan to kill me, and I have no intention of dying willingly. Rather…"

I was full of thoughts of killing him.

As I looked at the specter with such an expression, the specter's head twitched.

A purple aura began to swirl like a haze around him.

-Arrogant. It's a power worthy of such arrogance.

The specter nodded, as if acknowledging my words.

-However, you are an arrogant fool. I have achieved the Realm of Transcendence. Although I was sealed by a mere wench whom I could easily devour, my realm has been lowered.

The malevolent power possessed by the evil spirit began to amplify.

Whoosh! The shadows around us darkened. The creature's domain reacted. His murderous intent intensified.

My skin tingled slightly.

I moved forward with a smile. Good, it was fortunate that it was not a mere husk.

Or was it? Even among the Supreme Realm, it was certainly a strong one.

'But still.'

It was a half-baked being among the Transcendents. That's why it succumbed to the headmaster, got sealed, and its realm was lowered.

The headmaster wasn't strong, but her peculiar power was troublesome—a power that manipulated space freely.

Even I would struggle a bit with that power.

'The headmaster herself isn't strong.'

Step.

I walked forward. The evil spirit grinned at me. It seemed confident in its own power, as if it intended to confront me head-on.

I extended a sword engulfed in ashen flames. However, the spirit reached out its hand.

'It's too obvious.'

It appeared to be a straightforward confrontation. But that was just how it seemed.

The outstretched hand twisted, condensing an unholy force, and shot it at me.

Fwoosh!

The unholy force extended like a laser. I easily sliced it with my sword.

Wong!

The Black Demon Sword hummed. Clicking my tongue, I stored the sword in a subspace.

'To think it would groan at being strained by such a pitiful thing.'

This was why I didn't particularly like weapons.

Using power efficiently was fine, but even for me, it was impossible to conserve energy against such an entity.

If it didn't matter if the Black Demon Sword broke, I could wield it freely, but it held symbolic value.

I sheathed my sword and sealed the Heaven-Surrendering Arts into my fist.

-Puhahahahat! Foolish child! You don't really understand what a 'Domain' is!

"You think I don't know about Domain?"

-Yes, this is my Domain! I can use such power almost infinitely! Did you say 'capture'? This is capturing…

Wind God's Steps.

I jumped lightly.

My body became a dot in an instant and leaped forward toward the enemy.

-No… What?!

I became a dot at a dizzying speed and appeared in front of the enemy.

Bang!

Extended fist.

The enemy looked at me with confusion.

The enemy's eyes seemed to ask, "How on earth did you hit me?"

It was as if they were asking.

I grinned, showing my teeth.

I extended my left arm.

The green blade of the spear, wrapped in ash-colored flames, traced a line of ash.

Ssussusseut──!!

Dark lines appeared on the evil spirit's body.

The evil spirit clenched its teeth and unleashed a barrage of unholy powers at me.

Like a whip, the negativity twisted and advanced towards me.

'This is… unavoidable.'

I felt it instinctively.

Something that would certainly hit its target.

And usually, such things were dangerous.

If it had a guaranteed hit effect, it was likely related to curses or poison.

'If it's him, the likelihood of a curse is high.'

Or perhaps, it was both.

But, well.

'Even so, I can endure it with the Great Sky Dancing Divine Mantra.'

Something of a curse, filled with negativity.

The moment it touched my body, it vanished with a sizzle.

[The Vessel of the Archgod (Ex-) blocks the negativity.]

I could endure it with the Great Sky Dancing Divine Mantra, and there was even the trait of the Vessel of the Archgod.

The curse doesn't work?

"It seems our compatibility is quite good, doesn't it?"

As I spoke, I extended my fist. Bang! His face twisted. The Heaven-Surrendering Godly Technique forcibly shattered his spirit form.

Crack, something broke. A shield that seemed to surround its spirit form.

It seemed to have shattered.

-This can't be happening!

"Let me ask you one thing."

-How could I, how could I lose due to such a mere affinity! To someone who hasn't even reached transcendence!

"You said you created a domain to prevent what's here from leaking outside, right?"

-I'll kill you! If my curse doesn't work on you, then on your family, your friends, your comrades!

"You're noisy. Is it because you're nearing your end?"

I thought while casually responding to its words.

What should I do?

Should I use it or not?

I was conflicted. My Manifestation of Thoughts, which was only theoretically complete.

Moreover, the mirror of the Heaven-Surrendering Martial Emperor still remained. The success rate wasn't high.

'No, precisely because of that.'

Its domain surrounding this place was worth exploring.

Let's try it.

Here, no one would discover us.

Vroom vroom vroom!

Middle Dantian.

Two circles settled in my heart responded.

Brilliant Blazing Fire and Glacial Heavenly Moon began to spin fiercely.

Crackle.

The extreme energies of Solar and Lunar collided and repelled.

That created black lightning.

Divine Thunderbolt.

Flame.

Gray flames emerged from the palm.

Heaven-Surrendering Godly Technique.

It began to resonate with the Divine Thunderbolt.

[Unique Trait, Eternity imbues you.]

A blue power enveloped my surroundings.

In response, the stored Holy Power began to [Restore].

Long ago.

The technique obtained by killing the head of the Iron-Blood Sword Clan.

I kept thinking about that technique.

It would be great to fill this with Manifestation of Thoughts.

My Manifestation of Thoughts kaleidoscope was a mirror.

It stored the memories of my past life and restored them.

And then, it called forth the best version of me from the timeline, a Unique Trait, Eternity.

That was the structure of the Manifestation of Thoughts that I possess.

However, there was a drawback.

It ended permanently after three uses.

That iwas s a fatal flaw.

'If only I hadn't used it.'

I wouldn't have lost to the likes of the Insect Dragon King.

I wouldn't have been severely injured by the King of the North and died from the joint attack of the orthodox sects.

But I would have died before that.

I would have died in the fight against the King of the North if I hadn't had the power of the Purple Tower Master.

But there was a thought.

What if.

If I had created something other than the Manifestation of Thoughts with permanent consumption.

The thought that branched out from there.

As I experience permanent consumption, couldn't I awaken other abilities of the Manifestation of Thoughts?

The Manifestation of Thoughts I possessed, the ability of the Kaleidoscope, had two functions.

[Storage] and [Restoration].

That's why I [stored] everything I recalled from my past life while utilizing my unique ability.

At first, I did it just in case.

However, Han Seojin from another timeline cooperated, as if finding it amusing.

That was how it was created.

I formed a seal with my hands.

From behind me, I began to feel [something].

-What, is it?

The evil spirit spoke in a hollow voice.

As if it sensed its impending future.

Yet, for those who have reached the Supreme Realm or transcendence, that sense was nearly accurate.

Those who dealt with unholy power thought more vividly about their own death than anyone else.

'Do not worry.'

I wouldn't make you face eternal annihilation.

You would be used as resources to study the flesh of the demon.

I joined my hands together in prayer.

Manifestation of Thoughts.

Kaleidoscope Soul.

Behind me.

I sensed something there.

A blend of gray, black, and blue hues.

It stood about 3 meters tall.

It had two pairs of arms, one pair hanging down, the other crossed.

Its legs stood firm.

It wore a crown of dark blue, emitting light from where the eyes should be.

"Well, what should I call this?"

Magic and martial arts.

And Unique Traits and holy power.

The limitless creation from blending those.

My power that was born from it.

I shattered an object containing holy power and [stored] it.

Then [restored] it.

The limitless, condensed into a single point.

Originally intended for offense, the Limitless tends to rampage uncontrollably, but I wondered what would happen if I modeled it after my past self or my current self.

'Theoretically, it seemed feasible.'

Reality, however, was different.

But I was strong in real-life situations.

Others might say it was impossible.

Yet when creating Divine Thunderbolt and Heaven-Surrendering Godly Technique, most said,

It was too reckless.

But what about now?

I created those techniques and used them as my main techniques.

The downside was that Heaven-Surrendering Godly Technique could only be used by me.

Divine Thunderbolt also heavily relied on talent.

Most struggled to even begin.

The Limitless I created thus transformed anew.

Through my Manifestation of Thoughts.

Avatar.

It would not be an exaggeration to say it was Han Seojin with both spirit and body.

Magic and martial arts.

Holy Power and Unique Traits.

Another self that shared everything.

'That is precisely.'

My Manifestation of Thoughts, Kaleidoscope.

It was the Infinite Soul.

Crackle.

Before me, black lightning began to crackle.

At the same time, behind me, Divine Thunderbolt began to crackle.

"Divine Thunderbolt."

[Divine Thunderbolt]

The lightning of destruction, Black Thunder, struck the evil spirit.
