The Successor to the Underworld Is a Cheat Player

“That was you. Lucky.”

“No way. I may look like this, but I’m a strict person.”

The trivial conversation ended there.

“What happens from now on?”

Sein asked Arin.

A new identity emerged, a guardian named overseer.

Things would be different from now on.

“Going to Demorus.”

A natural course of action.

“While heading to Demorus, I will watch over you.”

She was his guardian.

“Regarding your suitability as Demorus’s successor.”

At that moment, Sein realized.

‘This is the main quest.’

His fourth life given to him.

As the successor of the Dark Alley, the main quest given to him.

“If you are not suitable?”

“You’ll be discarded.”

“That’s harsh.”

But it didn’t matter.

Sein’s goal he had held onto until now.

‘Survive.’

Surviving in this hellish world.

That’s why I’ve endured rolling in the filthy back alleys.

Getting my hands dirty with all that filth.

But if that was all, I would have given up.

Escaping the grim reality was also an option.

The reason I persevered.

“Alright. Let’s head to Demorus.”

It was a task akin to the mission Sein had.

The world he once loved so dearly, now his only way to atone for destroying it.

Also, the only hope Kim Sein, who had nothing but a past in security, held.

‘This time, I will clear Security.’

No one could curse at the cheat version.

Right now, this place might be a game for someone else, but for Sein, it was reality.

“From now on, let Wuis handle the management of Chichiron.”

Sein Family’s Number Three.

“Captain, but…”

“Whether it fails or is snatched by others, it doesn’t matter. Do as you please.”

Sein was preparing to leave.

“Ease up a bit, you’re more than capable of handling this.”

The reason Wuis, Number Three, took charge of the organization was simple.

Number Two, Deren, decided to leave with Sein.

“Captain, please return whenever you wish.”

The subordinates bidding farewell to Sein spoke earnestly.

“What if. Isn’t it better if he doesn’t come back?”

“What are you saying, Captain?”

Wuis, now representing the group, spoke to Sein.

“In the Chichiron alley, you were a ray of light in the darkness.”

“….”

“Still, because of you, the line-crossers were somewhat restrained, weren’t they? The residents of the alley were thankful for being able to live in peace.”

It was a past time.

The environment given to Sein was the worst, in itself.

Chichiron was more equal than anything else.

The issue was that the standard for equality was based on power.

Children, elders, all had to kneel and cry before strength in Chichiron’s back alleys.

“We’ll wait, abiding by the rules you set, Captain. Please return whenever you wish. Captain.”

“That’s enough. It’s getting awkward.”

As Sein waved his hand, Wuis finally closed his mouth.

“Is that all you’re taking?”

Arin’s question.

Now, it was time to leave, but all Sein had packed was a small bundle.

Even if Deren, the furry monkey, carried most of the luggage, it was still a meager load.

“That’s all.”

Yet, Sein seemed to have no regrets.

“This is Sein’s hometown, yet not a home.”

The essentials to bring were a few weapons and emergency tools.

“Deren, did you pack everything well?”

“Of course. Captain.”

Only a handful of coins scraped together from the back alleys.

“Weiss. Make sure the kids don’t go hungry. Deal with the thieves appropriately.”

“I will keep that in mind, Captain.”

Locked away for over a decade, all there was to take was just that.

A world coated in blood and filth.

To Sein, it was a world painted in crimson.

“Captain!”

Windows in the back alleys opened, people shouted.

“Thank you for everything!”

Sein, over eighteen.

Though young, his presence brought peace to the back alleys of Chichiron.

“Pah! Don’t come back again! Crazy bastard!”

Of course, that wasn’t the only thing.

“Weiss…”

“Yes, sir.”

“Take care of that punk later.”

“I will, sir.”

And so, Sein left Chichiron, a place that was almost like a second hometown.

Light footsteps that seemed endlessly light.

‘Finally.’

Chichiron, trapped by the constraints of the tutorial, could not leave.

There was nothing appealing, and each passing day felt like sinking deeper into a swamp.

So.

“Haha!”

Finally free, there was nothing to do but be satisfied with the present.

But even that joy was short-lived.

“Definitely…”

A quiet soliloquy.

The rest was left unsaid.

‘Changed.’

He was a saint who loved nature more than anyone else.

The azure sky and beautiful land.

In this world, there was nothing that wasn’t beautiful.

“It’s getting dark.”

The world he knew was no longer there.

Even though the sun was still up, the world seemed dark and ashen, as if covered in mist.

“Chichiron may be rural, but it’s a sacred land.”

He said, explaining like a child.

“You were protected by a barrier, so is this your first time venturing outside?”

“Yes, it’s the first time.”

The ashen world.

This is the current world.

‘Dark Sanctuary.’

Unlike the past when it was called the Sanctuary, this world had lost its light.

The once vast continent had shrunk by almost half, and even now, the human realm was diminishing.

“It’s because of the fall of the old empire.”

The fall of the old empire.

“The sacred light that protected the continent has disappeared, and darkness has spread.”

The great empire, Archipald, which safeguarded the Sanctuary in the past, had fallen.

No one else.

“It’s also because of the Emperor of Destruction.”

Because of their emperor.

“……”

It was a story they had heard.

Even though it might be considered a rural tale, it was not a story one wouldn’t hear.

The great empire, Archipald, which illuminated the Sanctuary, had lost its pillar of light and perished at the hands of the last emperor, also known as the Emperor of Destruction.

That’s it.

“Now it’s a story that’s over a hundred years old.”

A story from a hundred years ago.

‘I opened my eyes as a saint in the back alley….’

Yes.

‘A hundred years after I destroyed the empire.’

If it were the original Sanctuary, there wouldn’t have been such a time difference from my past life, but now it was a twisted world.

“Saint Demorus.”

He called Saint Areen.

“I only set the destination for you.”

The destination is clear.

Demorus.

“The path and method to reach the destination are entirely up to you to decide and pursue.”

Arin is the guardian of such a saint.

“I will watch over it and determine if you are worthy.”

“I understand.”

“Even if your life is in danger, I will intervene according to my judgment, and it would be wise to think that you won’t actually receive it.”

The day Arin faced him.

“You, on that day, exhausted all my help.”

As a mercenary of knight commander rank, the assistance he received from him was the only help Arin could receive.

“It doesn’t matter.”

“You are quite confident. The present world is so dangerous that it cannot be compared to trivial matters.”

“It doesn’t matter.”

Sein repeated the same words.

“If you can’t even endure that much, nothing will change.”

Sein’s clear goal.

It is to survive.

And to see the end.

How this world will end is unknown.

But Sein was convinced because he had seen the end of the world once.

‘There is an end.’

And reaching that end was the only path he should take.

‘For that, I must make the most of what I have been given.’

The last life.

A life as the successor of the Dark Lord.

A life dotted with failures.

The only success became a flaw due to misconduct.

It was an opportunity to erase all of that and start anew.

“So….”

Arin, in a strange voice, said.

“Is this really your first destination?”

A dying forest.

“Yes.”

Monsters lived within it.

*

*

*

“Kik… Kik.”

Softly spreading cries.

“Kik.”

It was like they were communicating with each other through those cries.

Those lurking behind dead trees as cover.

Those holding rusty swords, flipping mud.

“Peekaboo.”

It was a goblin, one of the lowest monsters in Sanctuary.

The goblin, startled by the sudden sound, tried to thrust its rusty spear, but it was too late.

Swish!

The sharp dagger had already pierced through the goblin’s neck.

“Squeak!”

Another goblin, sensing the ambush, shouted as a warning, but it was also too late.

Swish!

In no time, Sein had plunged the dagger into its chest.

Around Sein, the place was filled with goblin corpses.

“Not as challenging as I thought.”

As darkness crept into the continent and human territories shrank, the influence of monsters grew significant.

In the past, there were very few monster entities in Sanctuary, but after the darkness arrived, their numbers surged, and their levels increased.

“No, it’s definitely different.”

Sein had only encountered monsters through the corpses brought in by mercenaries.

Experiencing newly transformed monsters was a first for him.

“Squeak!”

A goblin, using a comrade’s corpse as a shield, rushed towards Sein from behind.

“Becoming more ruthless and stronger, aren’t they.”

Sein instinctively turned around and thrust the dagger into its neck.

Goblin group behavior was something seen only in special events, especially using comrades’ corpses as cover.

Thud, thud.

Coating a rusty spear with poison was unheard of in the past.

“Seems like things are roughly in order.”

A game turned into reality.

It possessed a realism incomparable to the past.

Swish!

“One left.”

Sein was astonishingly accustomed to it, having shed countless blood, even if they were monsters, not humans.

Squelch!

Rolling in the crimson, inside the dagger, inside the blood.

“It’s in bad shape.”

He could get used to all of this.

At the sound of Arin’s voice, Sein turned his head.

“If it’s a blade, it’s still usable.”

It was a dagger he had personally crafted, gathering the finest materials available in the alley.

“Not a blade, though….”

Arin was staring straight at Sein.

However, Arin didn’t respond.

“How long do you plan to hunt monsters?”

“There’s nothing better than experiencing real combat, right?”

Sain said.

“Humans have their limits, and you can’t just kill them however you want.”
