The Successor to the Underworld Is a Cheat Player

Thud! Thud! Thud!

Heavy footsteps.

Thud! Thud!

Even a skilled lumberjack would have to spend hours chopping before the trees collapsed like dominoes.

“Kieee!”

The roar echoed through the forest.

A special breed, accustomed to darkness after long exposure.

“Dark Goblin, perhaps.”

Monsters strengthened by being engulfed in darkness.

They exceeded the power of their ancestors multiple times.

Whoosh!

Moreover, they possessed their own unique abilities.

The Dark Goblin appeared.

“No, it’s a Dark Hob Goblin.”

With its massive frame, the Dark Hob Goblin approached, wielding a flaming greatsword towards Sein.

“Grk.”

At that moment, Sein, who had fallen, rose to his feet.

His body a mess from the brutal battle.

Yet, Arin could see it.

Snick.

A smile played on his lips.

“Finally, the boss monster has appeared.”

Sein had clearly been waiting for this moment.

“Kieee….”

His head slowly raised.

“Kieee-!”

The Dark Hob Goblin raised its flaming sword, letting out a roar.

“Finally, we meet, boss monster.”

Sein stood up, pulling himself off the tree he was impaled on.

A formidable foe at first glance.

Snick.

Yet Sein was smiling.

“Too big to be just a goblin, completely shrouded in darkness.”

Furthermore, the flames attached to the sword the Hob Goblin held.

No matter how special a species that uses abilities, it couldn’t possibly wield such a threatening power.

That.

“Is the current monster.”

A tainted, darkness-drenched special breed.

Thud!

Sein pulled out his dagger as he faced the approaching Dark Hob Goblin.

A dagger worn from countless battles, stained with goblin blood.

“Enough.”

However, it was enough.

Thump! Thump!

The Dark Hop Goblin, accelerating even more.

Sein, undeterred, began to walk towards him.

Thump! Thump! Thump! Clang! Clang!

Both increasing their speed towards each other.

Kwaaang!

Finally, they collided at the midpoint.

The blazing greatsword clashed with Sein’s dagger.

Aaargh!

Though there was a palpable heat,

“Fire Resistance.”

To Sein, it felt just like a gentle breeze.

The power possessed by the dragon, referred to as the strongest life form.

A new heart established through inheritance.

Thump!

The ability of the Dragon Heart.

Despite Sein’s dagger feeling like it could break at any moment,

Trembling!

It was still holding up against the impact of the enormous greatsword.

Ooong!

A blue light.

Emanated.

Kwaaang!

But ultimately, Sein fell back, unable to overcome the strength.

The Dark Hop Goblin swung the greatsword to pursue Sein, but it was too late.

“Keye?”

Sein had disappeared without a trace.

“Keyee!”

The enraged Dark Hop Goblin swung the greatsword aimlessly.

“Has intelligence diminished further?”

The voice came from right behind the Dark Hop Goblin.

Realizing the situation, the fellow tried to turn around hastily, but it was too late once again.

Whoosh!

A dagger, filled with malice, plunged into the Dark Hop Goblin’s back.

Just like that…

Thud!

Sein, infused with more magic by the dagger, was falling under the force of gravity.

“Keyeeeeee-!”

Screaming in agony from the stabbing pain on his back, the Dark Hop Goblin thrashed about.

Sain slowly widened the distance and killed the Dark Hop Goblin.

“Until regeneration.”

It seemed to possess even the regeneration ability that Hop Goblins originally didn’t have, as the torn wounds slowly healed.

“This much is not enough.”

Despite sighing with disappointment, a smile still lingered on Sain’s lips.

How long had he waited for this moment?

Monster hunting?

Of course, that was part of it.

But what Sain truly waited for was…

Thump! Thump!

A tremendous power felt from his heart.

“Dragon Heart, activating output.”

A sensation of becoming something beyond human.

Even when Sanctuary was just a game, he became addicted to that immense thrill.

And now that it had become reality…

“Ah….”

An indescribable sense of fulfillment dominated his entire being.

“Ahahaha!”

Sensory perceptions faded.

The system’s restraints disappeared.

Even when trapped in this hellish prison, Sain had awaited this day.

“This is definitely Sanctuary. Someday, when I awaken the power within me…”

What kind of sensation would he feel then?

Sizzle.

Sain’s pupils changed like those of a reptile.

At this very moment…

Whoosh.

Sain felt as if he had become a god.

The hard ground caved in under his footprints.

Using it as a stepping stone, Sain channeled an even greater magical power into the soles of his feet.

Kwaaaang!

Soon, Sain was soaring towards the Dark Hop Goblin as if he were a bullet.

The Dark Hop Goblin, a monster among monsters, fell.

Its demise was truly pitiful.

Shredded and torn to pieces, it seemed more like an experiment victim than prey.

“It looks like it’s been experimented on.”

The mad sorcerer had tried everything for his experiments.

Arin looked at the man who caused this scene.

His eyes closed momentarily as if mourning his prey.

When it rose.

“…….”

The man held a more refined magic within.

‘Has he gotten stronger in this short time?’

A growth that was beyond belief.

And Arin’s thoughts were indeed true.

Snick.

The man was smiling.

‘Leveling up in Sanctuary may be brutal, but defeating boss monsters gives quite a substantial experience.’

So she waited.

Slaughtering goblins, striving to call the leader who had them under his command.

What the man did was a kind of farming.

And now he had harvested the seeds he had sown.

‘My overall stats have increased quite a bit.’

Furthermore, in Sanctuary, one couldn’t acquire stats through leveling up; instead, stat increases were achieved through hunting.

Especially, the improvement in stats from boss monsters was quite significant.

‘I might not be able to do it twice, though.’

Through goblins, through Dark Hop Goblins, the stats that could be obtained would end here.

There would be nothing more to learn from an opponent who had become as familiar as it gets.

But what the man gained wasn’t just that.

Just now, by defeating a Dark Hop Goblin, he had once again leveled up.

-Jumadung.

The new ability obtained there was.

“Hmm?”

Dragon Fear.

It allowed him to exude a primal terror that only the mightiest beings could possess.

Arin furrowed her brows, looking at the man.

“Just now….”

Arin was about to say something.

“Oh, so this is what it means to live, huh.”

The one who made the move was the man.

“I heard about it from the mercenaries, but is it only after drenching yourself in blood to this extent that you can use it?”

Scratching his head, the man clapped his hands.

“Well, Arin. Is this right?”

Having questioned Arin, he fell silent.

“It’s a bit different.”

“So, did you figure it out on your own without learning? The path of a genius is indeed long and difficult.”

“…….”

Sein was smiling brightly at Arin, as if proving his innocence.

“Is this all you don’t know?”

Within, like he was examining a Dark Hop Goblin, he was scrutinizing Arin.

“Well, the ancient empire has perished, cutting off all bloodlines.”

He could be certain.

Because he was the one who severed that bloodline.

Already a hundred years had passed since then.

Through documents and stories, the uniqueness of the royal bloodline might have been passed down, but it was different from experiencing it firsthand.

Dragons that perished even when the ancient empire existed, and now, even the royal bloodline had vanished.

“No one knows the power of the dragon.”

Even if someone knew, when that time comes, he would be prepared as well.

Yet still.

“I must watch over.”

Sein didn’t let his guard down.

Just as Arin watched over him, he would watch over Arin as well.

Finally, Sein declared the end of the hunt.

“…Captain, well done.”

A hunt so intense that even Derun, who rarely showed emotions, seemed tired.

After the contamination from the darkness reached his chest, Sein’s hunt was considered over.

“I’ve obtained everything there is to obtain.”

Stats that could be gained from Goblins.

Stats that could be gained from boss monsters.

Two Moonlight Stones.

Leveling up while hunting Goblins was an impossible situation.

Moreover, he confirmed the limits of his current body in the fierce battles.

“The potential of the Dragon Heart is limitless. But for now, I must save it.”

He checked his trump card.

Above all, this was what mattered the most.

“Kuk.”

Contamination of darkness.

In a world different from the one he once knew, he had to make sure of this.

As the contamination worsened, he needed to understand the side effects it brought.

“Still, the Dragon Heart suppresses the contamination of darkness. Depending on the amount of magic power one possesses, the degree of contamination varies.”

This was what Sein needed to obtain.

And now that he had obtained everything.

“Let’s go.”

He could finally leave with peace of mind.

“If only I could control the contamination of darkness, I could act freely.”

Sein, who seemed relaxed, casually tied his hair back, but his eyes were deep in thought.

“If there’s one thing bothering me.”

Swoosh.

Aerin standing behind him.

Only her.

That moment.

“Sein Demorus.”

“……”

At Aerin’s cautious call, Sein slowly lowered his tied hand.

“Why?”

But as cheerful as his expression and tone, he spoke to Aerin.

“……”

Watching Aerin struggle to speak, Sein’s mind was racing.

“…It’s just that.”

“What is it? Spit it out.”

He still didn’t know much about Aerin.

A powerful woman known as the Witch of the Legion.

Her ability to tear apart elite mercenaries of knight-commander level was far beyond what Sein could handle at the moment.

But above all, what bothered him was her subtle gaze.
