The Reincarnated Person Became a Professor at the Academy

A legion belonging to the Immortal Demon King.

A legion possessing terrifying strength.

Unlike other legions, they wouldn’t break, and they trampled everything in their way.

As the name suggested, the Immortal Legion wouldn’t die.

Even when crushed, broken, burned, or torn apart.

They didn’t know how to die.

The higher their rank, the more troublesome they were.

For example, sword qi.

But even if there were ways to deal with them, the cost of eradicating them was too great.

Thus, the Immortal Legion was a terrible nightmare for lower beings.

Therefore.

They received the mission to bring Han Seojin, the vessel to become the Eternal Demon King.

Han Seojin.

The individual who had become the hottest topic in the current Academy.

He had imprinted his name on all the heroes in less than three months.

His strength was exceptionally high, but his level was still low.

His newly awakened Unique Trait was Reincarnation.

And people thought he had awakened a second Unique Trait.

– He awakened Eternity and then awakened Reincarnation.

That was the common thought of those who monitored him closely.

Therefore, the Demon Army sent the Immortal Legion.

He was already halfway transformed into the vessel of the Eternal Demon King.

However, some thought he might become an even greater Demon King.

The army following the demons,

The third woman, and the Immortal Legion also approved.

‘But what is that?’

What on earth is that?

The one called the Saintess covered her mouth.

Aaaah─!!

A hymn praising the demons resounded. Those who took out all sorts of weapons began to move.

The attire of the Immortal Legion is simple.

And there is nothing to block them.

After all, they don’t die. They feel pain, but they’ve been trained to overcome it.

The method of trading bone for flesh,

That is the Immortal Legion.

However.

That has now become the worst choice.

Crack.

Han Seojin swung his ashen-colored fist.

His fist landed.

And the soldier of the Immortal Legion did not even leave a corpse with one punch.

Ashen Flash.

It crushed the undying soldier.

However, the Immortal Legion didn’t even die from such destruction.

Even if their whole body turned to ash, they would revive.

That was the Immortal Legion.

But Han Seojin.

‘Is he breaking the immortality?’

He was killing the Immortal Legion.

That alone was shocking, but the speed at which he killed the Immortal Legion was unusual.

The vessel to become the Eternal Demon King.

Therefore, they assembled as many personnel as possible.

Ten mid-rank personnel.

One high-rank person called the Knight Commander and herself.

With this, they could wipe out any ‘clan’ or guild.

It seemed a bit excessive.

But now, she thought that her choice was fortunate.

Because even with this, the opponent was a reigning terror.

Hastily, the commander stopped Han Seojin.

“Stop!”

“Do you think I’ll stop?”

They were the ones who declared they would attack the Holy Empire Academy.

Moreover, they initially tried to kidnap him.

Punch.

As he administered a punch to another soldier of the Immortal Legion, the commander spoke even more urgently.

“It’s to make you submit! You can become the ninth Demon King!”

‘You’re so absurd that I ended up listening.’

Han Seojin smirked at the absurd words that made him laugh.

“What would happen if I submit?”

“You’d become a Demon King! You can rule one of the kings of hell, the ruler of the black sky…”

‘Sorry, but I already beat one of them.’

Oh, maybe not killed since he was already dreaming of revival.

‘If I killed one, I can roughly estimate.’

Insect Dragon King.

He was particularly strong among the Demon Kings.

Others mocked him as weak.

But Han Seojin knew that he hid his power.

“Stop talking nonsense.”

He clenched his fist.

The ashen haze began to thicken.

“Ruling hell or whatever, isn’t it useless? Just looking at you guys crawling out here, isn’t it obvious?”

They wouldn’t crawl out to a place like this if they were truly powerful.

Demon Realm.

That place was endlessly deep, dark, and vast.

“It’s inevitable. The hypocrites who claim to be the Celestial Gods. We have come here to kill them.”

There was something Han Seojin agreed with.

Seon Woohyeon.

Thinking about how he continued to suffer like that, it wasn’t easy.

They might be hypocrites.

No, I’m sure of it.

But even so.

‘Are they better than those who openly flaunt evil?’

Han Seojin stepped forward.

“Come.”

“You’re arrogant.”

“It’s not arrogance.”

Han Seojin put strength on his toes.

Swish.

A sound like the wind blowing was heard.

At the same time, Han Seojin stood at an incredible speed in front of the man.

Only two reacted.

The Saintess and the commander.

Clang!

The one called the commander raised his sword to block.

His sword, qi, blocked Seojin’s attack.

He was different from other weaklings.

But that’s all.

“The commander is in danger!”

The soldiers noticed the abnormality a moment later.

Clang!

The sword and fist clashed once more.

Just two collisions. The ashen power shattered the qi and cracked the sword.

‘Ugh!’

The commander gritted his teeth.

A massive amount of demonic energy drained out to block Seojin’s single attack.

Fortunately, the Saintess was there.

At the same time, all kinds of blessings began to be placed on him.

The demonic power began to rise.

[Trait, Zealot is activated. All stats increase.]
[Unique trait, Zealot’s Sword is activated. Speed increases according to faith. Attack speed increases by three times!]
‘Hmm?’
Han Seojin looked at the commander. The commander’s speed increased.

The commander moved his sword.

He couldn’t react before, but now he matched Han Seojin’s movements.

‘Hooh.’

Han Seojin sighed.

His movements became dramatically faster.

‘It seems to be his Unique Trait.’

Movement amplified by at least three times.

But it wasn’t fun.

He looked with his Heavenly Eyes.

The commander’s internal structure, filled with demonic energy, was boiling.

‘This isn’t fun.’

This level he’s seen many times in the martial world.

Hwaak!

Han Seojin’s eyes emitted a blue light. The eyes that saw through all mana shone blue.

‘Useless.’

He had already seen guys in the martial world who were just fast.

Some were fast yet profound individuals.

Some became tens of times faster in an instant.

‘Compared to those guys.’

They might be infinitely strong against those weaker than them,

But against the strong, speed isn’t that important.

Crack!

Han Seojin’s steps caused the ground to crack like a spider web.

Heaven-Surrendering Godly Technique.

Soul-Crushing Strike.

His ashen fist became a flash.

The commander quickly created sword qi, adding demonic energy to it as well.

Aaaah─!!

The choir sang to boost morale.

Ten zealots rushed at Han Seojin to stop him.

─────!!

There was no sound.

A massive shockwave shook everything around.

And what was seen was the commander whose upper body was pierced by something huge.

A handful of blood.

‘Huff.’

His body trembled.

It was the recoil from using Soul-Crushing Strike ‘properly’ once.

But it couldn’t be helped.

He was immortal.

No matter how resistant he was, theHeaven-Surrendering Godly Technique was specialized in breaking the opponent’s manifestation and traits.
Essentially, beings of a higher caliber than oneself.
“Phew.”

He breathed.

The Great Sky Dancing Divine Mantra, sleeping in his dantian, responded.

The Divine sleeping there opened its eyes and began to tune Seojin’s body.

‘Feels like I’m dying.’

Han Seojin moved his body forward.

At the same time, he stepped on the spearhead at his feet and picked up the spear.

Tap.

It seems they used a decent-quality item. The feel is quite nice.

‘These guys are more annoying than I thought.’

He held the spear.

His fists and feet were strong. They were good for dealing with strong opponents, but their reach was short.

It was good for dealing with one guy.

But in the current state, he needs to kill the opponents quickly.

Whoosh!

The end of the spear started to emit a mixed energy.

The ashen power flickered at the tip of the spear.

Heaven-Surrendering Godly Technique.

It was originally used while wielding a weapon.

But weapons couldn’t withstand the power of Heaven-Surrendering Godly Technique.

The current body, reminiscent of a diamond, also couldn’t use the Heaven-Surrendering Godly Technique for long.

“This is dangerous! Even if you get hurt, it’s fine. Capture him somehow!”

At one man’s words, dozens rushed at once.

Han Seojin smirked.

‘Normally, it wouldn’t be strange to run away.’

Zealots don’t hesitate to sacrifice for their purpose.

The funny thing is they truly believe it’s a noble sacrifice.

‘This is actually good.’

He can kill them all at once.

Heaven-Surrendering Godly Technique.

Flash Wind Slash.

The ashen light flashed.

Like drawing a line on a black background, the ashen color streaked.

Swish, swish, swish.

Lines were drawn.

In the world where everything stopped, dozens of ashen lines were drawn.

Splurt!

Flash Wind Slash.

A Heaven-Surrendering Godly Technique using a weapon.

This martial art, which maximizes the sharpness of weapons, is very good for dealing with weak opponents.

‘The remaining ones.’

Han Seojin looked elsewhere.

Half were left.

But their strength was weaker than those who had been eliminated earlier.

Most of them were priests called the choir.

Tuk.

The silent Saintess stepped forward.

Her hands and feet trembled.

Fear.

That was part of it, but the Saintess shook her head.

It was ecstasy.

‘The vessel of the Demon King?’

It was already perfectly completed.

The Eternal Demon King.

The leadership judged him to be on par with other Demon Kings.

Though his attributes are tremendous, they thought he couldn’t fully blossom his power due to Han Seojin’s talent.

But what about the current Han Seojin?

Overwhelming.

He glanced at the Immortal Legion and tried to challenge them head-on.

And he had already eliminated half of them.

“Ah…”

And now, he intended to deal with the rest of them.

Han Seojin quietly revealed his qi.

Hwaak!

An overwhelming aura burst out. A temperament that seemed like it would destroy everything.

At the same time, the Saintess saw.

A way for them to somehow escape.

“This time, we will retreat.”

“Then you’ll come again next time.”

Han Seojin said, resting the spear on his shoulder.

The Saintess swallowed her saliva. His expression and gestures were utterly relaxed.

But she thought it was fortunate.

‘At least he intends to talk.’

Han Seojin was a bit tired.

The Saintess thought. The current situation of attacking the Holy Empire Academy.

The one who would become the biggest variable had already started moving.

They were just buying time to prepare for the future.

The Saintess quickly retreated.

Slash.

A step late, a mark like something had been cut appeared where the Saintess was.

“Good sense.”

“Do you really intend to see this to the end with us!?”

“It’s ridiculous for the ones who kidnapped me to be now negotiating.”

Han Seojin slowly gathered mixed energy.

‘I’ll have to push myself a bit.’

He took a stance.

The opponent must be pushed at once, full of thoughts, to escape.

Moreover, they are the ones who kidnapped him with some unknown power.

If left alive, it will surely become troublesome.

So.

‘I’ll end it here.’

Wind God’s Step.

Swift.

Heaven-Surrendering Godly Technique.

Flash Wind Slash.

“What do you…”

Everything slowed down.

In that world, the Saintess noticed a moment late.

‘Huh.’

It was strange.

The Han Seojin she had seen just moments ago was no longer visible.

Not above, not to the left, not to the right, not below.

He was neither felt nor seen.

Tap.

A small footstep was heard from behind.

And it was endlessly ominous.

The Saintess turned her head.

Han Seojin was quietly standing.

The spear he was holding was shattered into pieces.

And.

One line was drawn.

The creepy ashen line that killed dozens of soldiers of the Immortal Legion.

“Ah.”

Upon realizing that, the Saintess saw a world turned upside down.

‘De…mon… King…Please, be wary of that existence.’

The last prayer of the Saintess, who prayed in the moment of death, went unheard.
