Chapter 115 – Culvert

“It’s the Demon King soon.”

At the words of the hero, everyone nodded with a tense expression.

As if the rumor that the Demon King’s Castle was right in front of his nose was not a lie, he was intimidated by the insidious and overwhelming energy that he could clearly feel.

The strength of the demon lord has always been explained in the game, so there is no need to explain further.

As a result, it would be most accurate to say that it was an opponent that could not be killed. Because it is an opponent that cannot be killed by any means, it is impossible to win in terms of the game system.

Anyway, no matter what method I used, it was directly connected to defeat, so I couldn’t help but be nervous.

But I had to do it.

Otherwise, the world will eventually perish as planned.

“You don’t have to worry about the road to the inside of the castle. I have absolutely no intention of going to a place with tight security.”

The hero said that and started drawing a picture of the demon castle.

At first, I wondered what to do by drawing a picture in a place like this, but the picture was very detailed like a warrior who remembers the castle of the devil clearly.

“This is the inside of the castle.”

– How do you remember this… ?

I was asking because I was genuinely curious.

The warrior just laughed at my question.

Is this something to laugh at?

Hold on because you look good

[… ]

I felt like Rumia was looking at me with her cold eyes, but she must be to blame.

Anyway, the hero continued his explanation.

“If you go this way, you might get caught right away. But going in the other direction is suicidal.”

Before returning, in order to somehow clear the castle, I went everywhere to find the safest way to the inside of the castle, the throne room that could be called the heart, but in the end, I found only one place.

“It’s the groundwater.”

It was an underground water inside the castle, and it was to use it to go up to the top of the castle.

“Is that possible?”

“I hear the throne room is at the top? But how do you get into the aqueduct?”

Oh…

The warrior is really serious.

The way to enter the underground waterway is the same way as in the game.

It was the safest way, but it was also the most complicated and exhausting way to move. First of all, you have to find a suitable ladder among the underground waterways and go upstairs to infiltrate the castle, so you have to use only secret passages to avoid being caught.

“Of course, it doesn’t go directly from the canal to the top. Didn’t I tell you last time that I knew the inside of the castle? We have to move as unnoticed as possible.”

Saying so, the hero drew a line inside the castle and eventually drew a picture of arriving at the throne room and stood up.

“It’s understandable that you’re worried because you can’t just draw a picture right here and now. But for now, I want you to trust me. I will never lose you guys.”

Never.

Saying so, the hero took out a map from his bosom.

“That?”

“The first thing I did when I got back was… It was to record all the secret passages inside the castle that I remembered.”

“Then start it… “

“You don’t know what it is if you just show it.”

Oh yes.

The contents of the map were actually an anatomy of a castle, so it would be hard to figure out what it was if you just showed it.

The picture shown by the hero only showed the overall appearance of the castle and how to enter the underground waterway, so it was possible to see it vividly like 3D, but it was impossible to see the inside of the castle.

‘No… He was really crazy. ‘

Examining the anatomy of the castle, I gasped in amazement.

I felt extraordinary at the point of returning to the past to save myself, but I never dreamed that I would have memorized the inside of the castle crisply and even made a map based on it and thoroughly prepared.

Even I, who had knowledge about the game, was in a situation where my memory was ambiguous, but the warrior boasted such a perfect memory that I wondered if I was unconsciously watching something like Namuwiki.

Even the map right away was the same as the inside of the demon castle I knew.

In addition, the locations and directions of secret passages that often appear in strategy guides were all connected in detail.

It was even more strange that I couldn’t pierce this.

The hero turned to us and asked if we were ready.

Ready, of course it was over a long time ago.

I got up from my seat.

“Don’t worry. I will make sure you never meet another demon.”

Is that what the warrior said?

I became very willing.

Even so.

That… Unlike usual, if you get caught wrong, it’s the end, so wouldn’t it be better to let them escape in advance?

Thinking so, I called the warrior.

At my call, the warrior turned to me as if asking what was going on.

– Wouldn’t it be better to install a teleport magic circle in advance so that you can escape if something happens… ?

The hero shook his head at what I said as I opened the drawing board.

Oh, isn’t this?

“There is a special barrier that blocks the magic itself from moving outside. Maybe… Even if we set up the magic circle in advance, we won’t be able to escape.”

“… “

No something like that

Ah…

No wonder…

Inside, pressing the map to move to another waypoint itself wasn’t used, so that’s why.

Get to know one

“Well then, shall we go?”

“Huh.”

“I thought it would be a very long journey, but it wasn’t as long as I thought.”

The brave warrior answered Ruril’s words with a smile.

“If I had traveled as usual, it would have taken more than three years.”

“Ugh… “

I guess so.

At that time, it was only natural that it would take a long time of three years, as they reached the castle by taking them one by one from the beginning.

Right now, they are moving to catch only the demon king, leaving everything else behind. No matter how strong the warriors are, if they notice our presence from the other side and start an all-out attack, no matter how strong they are, it will be impossible for them to protect us and hold on.

Even Cecilia’s divine power, which exerts strong power because it is inside the Demon Continent, let alone the enemy castle itself, would not last long.

“So, as quietly as possible… I have to move as I move. And Rumia, you use stealth magic when I signal.”

Saying so, the hero moved to the bottom of the castle, to an invisible place.

It was dark and smelled bad, right under the huge bridge leading to the aqueduct.

It’s groundwater, so it’s natural.

Usually a place like an underground waterway smells really bad and dirty.

And there was a monster to be careful of when moving to the underground water canal in the game.

The hero probably prepared for that monster in advance.

Stealth magic wouldn’t be bad.

“The kids up there are probably lesser demons. Originally, the higher you go, the stronger you get, but… These are the kids we don’t have to deal with now.”

Saying so, the hero arrived at the door inside the underground waterway.

In the game, it was designed to prevent entry into the underground water without a key. I wondered if I couldn’t just break it in, but according to the game system, no matter how many skills I used, it wouldn’t break, so I just went back upstairs and stole the key from the guard and came here…

“Done.”

Indeed, the hero simply unlocked the lock.

Judging from the fact that the hand was filled with divine power, it was clear that the lock was also filled with demonic energy, so it was made so that it could not be damaged by moderate attacks.

I wondered why this place was so lame, and that was the reason.

“It’s definitely inside the Demon Castle, but it doesn’t look like the Demon Castle… “

I involuntarily nodded at Ruril’s words.

Obviously, if it was the Devil’s Castle, it would be very guarded and dangerous, but since I followed the hero, I couldn’t see anything really dangerous.

“Don’t worry, demons don’t roam the canals. Only… “

“Only?”

As soon as the hero finished his words, something that looked like a shadow came over us.

However, as if the hero knew it, he took out his holy sword and cut it very easily. Dark red blood gushed out and the monster, which had let out a scream close to screaming, collapsed as it was.

The Holy Sword was slightly released.

“After… I hope you run as soon as you come in. I will have to walk slowly now.”

I nodded at the hero’s words and cast stealth magic on everyone.

Casting the stealth spell as soon as I got inside, that was what I had to do.

This was the beginning of the journey to subdue the real demon king.

I looked around the underground aqueduct in a cold sweat.

Not yet… It seems like a long way to go, though.
