I upgrade alone

Seeing Cheng Jin-Woo's serious face, Ai Xier's expression darkened.

'Is it the enemy of the devil that the system wants to cover up, or the reason for the war? Or the result?'

Thinking of these, Cheng Jin-Woo narrowed down the scope of the question.

"Who is that powerful enemy?"

at this time.

Aisher froze like a toy without electricity.

However, this is just the beginning.

"what......"

Frozen all over, she lost consciousness and collapsed to the ground.

Cheng Jin-Woo quickly supported her and made her lie on her back. Ai Xier's breathing was very steady, and her body seemed to be fine.

It's just that her expression was wrinkled, as if she felt tight in her chest and couldn't breathe.

Cheng Jin-Woo used his hands to tear off the armor on her body in order to let Ai Xier take a good rest.

Armor is easily taken off.

Then he tore off the cloak behind the armor, folded it and used it as a pillow under her head.

Although it is a relatively tedious job, it is not done for her because of kindness.

If it weren't for this guy, it would be impossible for me to get relevant tips.

'Enemy of the Devil...'

For those guys' identities, the system's reaction was too sensitive.

'Is there anything special about them?'

They have great power, and for some reason, they have affected both the earth and themselves...

Seong Jin-Woo called out to the store.

I wanted to wake Aisher up with potions, but it didn't work.

'Can we just wait?'

Cheng Xiaoyu sat down beside Ai Xier with a bang.

While waiting for Aishier to wake up, he began to sort out the clues he got in his mind.

***

"Um?"

Suddenly, Ai Xier raised his upper body.

Sensing an aura that didn't belong to her around, she looked aside and found Cheng Jin-Woo and shook her shoulders in shock.

'So it wasn't a dream. '

Aisher, who gradually recovered his consciousness, looked around.

The corpses of high-level demons are everywhere.

Ai Xier was dumbfounded.

Demons without wisdom don't think that demons with wisdom are their own kind, and the unconscious self is the same as the prey here.

But I am still alive and well...

"Have you been protecting me?"

Cheng Jin-Woo didn't answer, he got up and held out his hand to Ai Xier.

Ai Xier grabbed his hand with a moved face, and stood up cautiously.

"Thank you."

"How far is it to get to the place with the permit?"

"We'll be there soon, let me lead the way."

Ai Xier stuck his wrists together and stretched out his arms in the direction of Seong Jin-Woo.

"...?"

"...?"

Cheng Jin-Woo and Ai Xier looked at each other suspiciously, and Ai Xier spoke first.

"I'm a prisoner, so tie me up..."

"Need not."

Even if you don't need a rope, you can hold down the enemy who is resisting or fleeing, so there is no need to waste time on this kind of thing.

Seong Jin-Woo put his hand on Ai Xier's shoulder and made her turn around, then he patted her on the back.

Ai Xier, who was probably still afraid, had a heartbeat that quickened a lot, Cheng Jin-Woo didn't say much about it.

Seong Jin-Woo looked at the horses they were riding before.

"What about the horse?"

"I'll take it with me."

Aisher grabbed the reins of the three horses with a flushed face, and walked ahead alone.

Cheng Jin-Woo quietly followed behind her.

***

As Eicher said, the two quickly arrived at the place where the pass might be.

It is a huge castle.

'There is a Castlevania in the Castlevania...'

Castlevania just has the word city in its name, but it is actually a tower. The building in front of it is more like a medieval style ancient city.

The soldiers guarding the city gate became nervous when they saw Cheng Jin-Woo.

but…...

"This is a guest."

After Ai Xier finished speaking lightly, she gestured with her chin, and the soldiers quickly opened the city gate.

Soon, a group of knights in the city came out.

"Master Aishir, we have been waiting for a long time."

"Where's Dad?"

"In the reception room."

"understood."

Knight secretly glanced at Cheng Jin-Woo and asked her.

"Master Aisher, the man behind you is..."

"He is a distinguished guest, please treat him well." Aisher said in a serious tone.

Hearing this, the knights all lowered their heads and made way for the two of them.

Cheng Jin-Woo followed Ai Xier and walked into the deepest part of the castle together.

After going down the stairs for a while, a spacious room that looks like the boss room came into view.

'Is this the reception room?'

Cheng Jin-Woo looked around.

Except for the strong pillars that extend to the sky on the side, it seems to be a place for people to fight, the entire space is empty.

'If I call all the way, this is probably the room of the ultimate boss. '

There is a giant chair on the altar in the depths of the reception room, and the demon noble sitting there must be the BOSS.

Ai Xier and Cheng Jin-Woo stood in front of the boss.

"Aisher." The BOSS spoke first.

"Dad, this is..."

Before Ai Xier finished the introduction, the boss stared wide-eyed as soon as Cheng Jin-Woo and Cheng Jin-Woo looked into each other's eyes.

The pupils of the BOSS trembled.

"You, you! Who did you bring back!"

"Dad, he's a guest..."

Although Ai Xier rushed to explain, the BOSS was still very excited.

"Guests? How can guests come in with an army?"

"what?"

Ai Xier looked back at Cheng Jin-Woo.

Where is the army that Dad said?

The boss stared at Cheng Jin-Woo closely, and tremblingly said: "Ai Xier, can't you see? A group of soldiers hiding in his shadow."

Hearing this, Cheng Jin-Woo's eyes changed instantly.

Aisher was taken aback by the sudden change in the atmosphere, and quickly took a step back.

Cheng Jin-Woo looked surprised.

'This guy seems to have a strong sense of breath. '

The boss seems to be able to see the soldiers hiding in his shadow.

'It should be said that it is better to be lucky, or to be unlucky. '

In order to deal with sudden battles at any time, he recalled all the shadow soldiers back to the shadow just in case.
