The Successor to the Underworld Is a Cheat Player

“Damn it….”

An endlessly irrational contract.

However.

“…if that’s the case, you should have said so earlier….”

It was himself who wanted to pierce his heart.

“I… contract.”

[You despicable creature.]

His consciousness began to blur.

[Very well. I, the Archfiend Achipald, contract with the reincarnated Kim Sein.]

“What…!”

But Sein couldn’t continue.

*

-It’s disgusting to be in the same class as someone like you.

“Eating together at lunch…? Have you lost your mind?”

“I’m sorry.”

Damn it.

If only he could curse like that.

Memories he wanted to forget.

Things buried in a corner of his mind were resurfacing.

-Do….

Pain in his heart as painful as the memories.

“Sh…it….”

Sein, with blood vessels bulging on his forehead, uttered his first words as he opened his eyes.

“Now you seem to be coming to your senses at last.”

A sly voice echoed in his ears.

Sein turned his head slowly.

His second utterance was,

“You crazy bastard.”

It was also a place of curses.

There, Arin, a beautiful woman with black hair, was seated.

She sat in a chair, reading a book.

This was the Cyclops’ hideout.

“What on earth have you done?”

Thud.

Upon Sein’s words, Arin closed the book and gazed at Sein.

“Exactly what have you done there?”

Her mind, which had faded into terrible agony, now sharpened.

But one thing was clear.

– Do not contract. Former life, Kim Sein.

The Dragon of Destruction, Archfold.

Even the Primordial Dragon, said to exist only within the settings of Creation, was present there.

“Why is there a dragon?”

“Indeed, you’ve finally encountered it.”

It was the first time.

Arin’s pupils shook.

“It’s true that you made a contract with a piece of the dragon.”

“What?”

“It’s something even I cannot guarantee. I wasn’t even allowed to set foot there.”

Sein rose slowly from the bed and sat up.

“That place holds the Empire’s greatest secret, a prohibition so grave that unless it poses a threat to the Empire’s downfall, one cannot even approach it.”

As expected.

“My father couldn’t go there, but he informed me about it. However, all I found there was endless terror and despair.”

Arin spoke.

“But you seem to have met it.”

The Dragon of Destruction, Archfold.

“Truly, you are the harbinger of destruction.”

Arin examined Sein’s body, who had already lost consciousness.

Sein’s body was covered in mechanisms even Arin couldn’t easily discern, but she understood.

She found a way to bypass Sein’s locks, stopping his heart.

“The Destroyer is described as the most formidable being in the Empire’s history.”

Arin spoke as if telling an old tale.

“Dealing with the magic and divine power of dragons.”

The secret that had not been revealed until now.

“He even handled magi.”

The Destroyer, wielding a power that could not be matched.

He was undoubtedly a being worthy of being called invincible.

No one stood in his way, not even the noble bloodlines of the royal family kneeled before the Destroyer.

There was a force that rendered competition meaningless.

“Even now that you know, will you treat me as your master?”

The shadow serving the royal family, Seymour.

“The empire has fallen. Seymour’s oath has been annulled. By your very hands.”

“It stings.”

“So, I propose.”

Arlene, her obsidian-like pupils fixed on Seymour.

“Let’s make a deal. The price has surely been paid.”

The price…

“To the point of overflowing.”

One is spineless if not satisfied.

A man drenched in blood.

His white hair, symbolizing purity, seemed dyed with red flowers.

His dazzling sky-blue eyes, like lakes plucked from the heavens, flickered with madness.

Shuaaa-!

As the sword swept, a crescent-shaped black light poured forth, cleaving a dozen orcs in an instant.

“This is the taste.”

Seymour.

Arlene’s test, a week had passed since she made a pact with the dragon.

“You’ll need time. For your body to adapt.”

She proceeded with the deal with Arlene.

To fulfill her wish, she promised not to spare any support for Seymour.

It could be said that their relationship was not merely that of a mentor and a candidate, but rather one of equals, closer than that.

-Elixir.

Indeed, she did not lie.

“Re, rewards!”

Already content with the rewards she had given.

“Aren’t orcs a warrior tribe?”

“Rewards!”

“What are you trying to escape from?”

Swish!

Arlene even gifted an elixir that was difficult to make, despite having the recipe.

Seymour, a mix of various energies, unable to harmonize.

To solidify his vessel further, to stabilize it quickly.

The elixir that could revive the dead, used merely for the stabilization of power.

“Is that all of you?”

“…Rewards.”

The outcome was clear.

“Not entertaining. I’ll send them away. Me.”

“Rewards?”

The orcs, known as the Warrior Tribe.

Those scoundrels who once raided villages near Borfeo were now wide-eyed in surprise.

Faces contorted with fear soon turned to hope.

Swoosh!

Followed by a sense of betrayal.

“It’s a lie.”

Sein once again overcame the orcs.

“You’ve never spared anyone, have you?”

Slashing and stabbing, cutting through.

Gooo-!

The power surging within his body was beyond control.

Through Arin’s trial, he had gained something significant.

First, the magic of the Dragon Heart surged.

From the backlash of the Blessing Fragments, the corroding magic, all the way to the penetrating holiness.

Like muscles regenerating from wounds, the Dragon Heart fought against them as if it were their essence, swelling its own size.

“The cleanup is done.”

The remaining energies followed suit.

Restraining each other, bloating their sizes in defiance, they repeated the clashes.

This was the result Sein had originally desired.

‘The ultimate build.’

Containing the energies of extremes within one body and surging them.

Without using separate techniques, the energies fought among themselves, devouring and growing stronger, increasing their sizes.

Though this process brought great physical pain, in the past, it didn’t matter as it was just a game.

And now.

“Tsk. Something’s missing.”

Marung.

Sein, being his own body, could sense it.

The nature of the Dragon Heart, which could be considered his core, had changed.

Where Sein’s build once delicately balanced three energies, his body now had lost that equilibrium.

Kwoong! Kwoong!

The heart of the dragon, or rather Marung, completely enveloped everything.

And it seemed to speak.

-Obey.

However, the magic and holiness, being entities of their own, were striving to grow even larger and stronger to resist such an overlord.

Therefore, there was no pain.

Marung’s heart, overwhelming everything, protected Sein.

“That’s enough…”

Before him stood a troll, stained black.

It had wreaked havoc after ravaging the forests near Borfeo.

“There’s a certain pleasure in this.”

“Kuoooo!”

It seemed like Oh Meter would be overrun as the Dark Troll roared and charged towards Sein.

Swish!

*

The massive Dark Troll lay there, now a lifeless body.

And Sein, sitting atop it, finally wore a satisfied expression.

“At least Level 10.”

This frenzy of hunting was not just to unleash overflowing power, but also to understand oneself.

Mana, magic power, and divine power not only served as fuel for special abilities but also directly influenced the body.

In other words, they affected the stats.

Jumping off the troll’s corpse, Sein stretched his body.

The physical stats were around Level 10 of his final build.

Regained rewards.

“That alone wouldn’t cut it.”

Indeed, the most significant impact came from that.

“Must be due to the contract with the Dragon.”

The contract with the Dragon, Archipald.

It had a tremendous impact.

The most crucial point was that he was still only Level 4.

“Leveling up seems tougher now.”

Thanks to the peculiar experience point system of Sanctuary, leveling up had become more challenging, but he was content.

“Because…”

Grin.

Korean gamers would acknowledge.

“Reaching the highest point is the best.”

At the limit that one would eventually reach, they would possess strength incomparable to others.

“Is all the chaos over?”

Arin gracefully walked through the messy field of corpses.

She had been watching Sein’s hunt all along.

“Mostly. But still a long way to go.”

“Dismembering the Dark Troll?”

Arin asked, looking at the Dark Troll’s corpse behind Sein.

Grin.

Sein smiled at the sight.

“Why? Disappointed?”

“….”

Arin, hastily trying to make sense of Sein’s words.

Sein seemed to be grinding his teeth at that sight.

“Even if you didn’t know you were a necromancer, you would have been beheaded straight away.”

“Is that so?”

A deal.

No, Arin and Sein made a contract.

For Arin’s purpose, to achieve Sein’s goal.

Once known as the Harbinger of Destruction, now a thing of the past.

-Let’s start on equal footing.

Not the Harbinger, but Sein Demorus.

Not in the shadow of the royal family, but as Arin.

“Curious?”

Arin narrowed her eyes at Sein’s words.

Nevertheless, Sein did not stop speaking.

“I told you. You’re far from being enough.”

Only then did Arin seem to understand Sein’s words.

Roar!

A surge of death rushing in.

Suddenly, spider legs sprouted behind Arin.

“Well, it must have been necessary. To show you the extent you need to be aware of to prevent impulsive actions.”

Arin’s voice was cold.

“Whatever you were in the past, you have made a contract with the Dragon now.”

Kwaaa-!

As Arin released some of her power, the wind howled.

“This world is not to be underestimated.”

At that moment.

Swish!

Sein’s figure vanished.

“Indeed, will it be so?”

Behind Arin, Sein, wavering like a shadow, was thrusting a sword without hesitation.

“A deal is a deal.”

The deal made with Arin.

“Debts must be repaid.”

A debt forced into the Dragon’s nest against her will.
