That time I got reincarnated as a slime,no, a DRAGON?

CH-45

Rimuru's POV

It is finally the day that we go to explore the ruins. We were completely ready for the exploration. But for some reason Milim kept demanding to wear proper exploration clothes that she had seen in a manga. Shouldn't have let her seen that. Anyway, after I told Kaijin about the gun, they took a quick interest and made a prototype. It was quite good. It used magic circles to explode, so no gunpowder. It also had two types of bullets. Normal lead one and magically enhanced ones to attack monsters. I had brought Shion, Gobta and Ranga with me.

We then departed to the Free Guild in Ingrassia. By depart, I meant teleported. We were welcomed by Kagali.
"It is a pleasure to meet you again, Demon lord Rimuru. I guess this is the first time we meet, Demon lord Milim."
"Hmm? Hi. Nice to meetcha. I am Milim."
What was she thinking? Whatever.
"Anyway Kagali, are you guys ready?"
"Yes. Our team is here, so let me introduce to them. Please follow me."
"Yes." I say.

While we were going to the venue, I whispered to her," Did she bite?"
"Yes. They are planning on releasing the Chaos dragon."
"The one rumored to be Milim's pet?"
"Yes."
"I see."

Chaos Dragon? It has the same race as me. I wonder how it is. According to Milim it is a mindless beast, but I still want to see it. I have never seen another monster of my race, after all.

We then reach an open field. A group of people who would be joining us on our expedition. Kagali then introduced them to us. There were ten people in total. They were heavily equipped with all the things they might need.

"We will carry your stuff Rimuru-sama, so please give it to us."
"Oh, no need to worry about that. We can use spatial magic." I say pulling out a map of Jistav out of my stomach and putting it back in, like a demonstration.

"But-but even your bare skin is showing. It is not advisable to have bare skin."
"Don't worry about that. Both me and Milim have strong skin." I say and show my scales which are usually hidden under my skin. They seem to be a bit surprised by it but regained their composure quickly.

"I-I see."
"We have booked a wagon to go to Jistav."
"Wagon? Why? We can just teleport there."
"Teleport?"
"Yep." I say and open a gate in front of me.
"Follow me." I say but Milim just enters before me. They all follow behind me soon enough.

We came out right in front of the castle of Jistav. This territory now technically belonged to Milim but I still had quite an influence here. Especially amongst the locals who were freed from Clayman's rule. The dark elves gathered their bowed.

"Welcome to Jistav, Rimuru-sama, Milim-sama and their companions."
"Are the rooms ready?"
"Yes, shall we take you to your personal chambers or the group room."
"Lead us to the group room first, we will keep our luggage there."
"Understood. Please follow me."

While following the dark elf woman who seemed to be the eldest. While walking, I could hear them talking behind me.

"This is insanity."
"How have we already arrived? It hasn't even been an hour since we departed."

They followed us in an odd manner. I guess they haven't caught up to reality yet.

"You are Rimuru-sama's guest. If anything troubles you, please inform us at once." The dark elf woman said with a slight bow.

We then took a tour of the entire castle.
It was spotless. They must have been maintaining this entire place.
"Milim, this place will be officially yours after this expedition. I guess these guys still want to live here."
"Yep. I see that. I will have them provided with regular food and supplies."
"I am grateful, Milim-sama."
"Hahaha. No need to worry. You are my people after all."

Looks like Frey's efforts really are paying of. We then continued to explore. Finally we reached the basement.
"This is the entrance to the ruins. The first section is where we live, so it is completelymapped."
"I see."
It was literally just below the castle. I go towards the door. I felt an odd attraction towards it. I move towards it and open it. Even though we are supposed to be underground, there was quite a bit of light there.

"What's this light?" An explorer asks.
"That is a perpetual effect. It turns dark at night and becomes brighter as the Sun rises outside."
"Heavens! Technology from ancient times."
"I would love to take a look at this machine."
They continued to continue this question answer round for some time. Meanwhile, I had noticed something that caught my eye. The design of ruins looked just like ancient kingdoms, nothing out of the ordinary. But in some places there were different designs. These designs appeared to be older than the rest. It doesn't appear to be for artistic purposes.

>Raphael, how old are these?<
<Understood. Using carbon dating to find their age. Successful. They are dated to be nearly 55000 years old. The nearby ruins are about 2000 years old.>
>55000?!? Shouldn't that be older than this world itself? Didn't Veldanave create this world 50000 years ago? And why does this design seem familiar? <
<Unable to answer. Not enough data. The reason these seem familiar is because these are a part of the defense design 'Hell Paradise' that Master had read about in his past life.>
>Hell Paradise? Wasn't that a defense system which had a maze and a fake base containing some important stuff, so that intruders believe they have reached the base but the real one is hidden even more underneath?<
<Correct. It was made in 2104 by Lucas Erwight to defend against insect-like race which had low intelligence but large numbers.>

I see. Also this device. I have some doubts about it.

"By the way, the machine that keeps the light on, does it feed on magicule?"
"Yes, of course." She made a face as if that was obvious.
"Alright. Could you lead me to the machine."
"I am sorry, Rimuru-sama, but I don't know where it is located. I only know that is further down." She says then lead us to the way deeper into the ruin.
"I see. Let's see if we find it this time."
"Hai."

After that we continued through the first part. It had a few houses and other buildings. We then continued till we reached a door.

"This is the door to go further down. Only Clayman-sama held the key so we can't go any further on our own."
"Hmm? Then let me destroy it." Milim said. I then proceeded head chop her before she actually does so.
"We need to examine the door first. There may be some sort of defense system."
"That is correct Rimuru-sama. This appears to be a part of the defense system. If not handled properly, it could cause the entire defense system to activate."

"This will be interesting."
"It might be long though."
Looks like the team is enthusiastic to start deciphering the code. They get to it. I didn't want to spoil it for them, so I didn't intervene. With thought acceleration, I had solved it quite quickly. It took me around 5 minutes in thought acceleration. It was very similar to puzzles. It didn't take them much either. They managed to solve it in about 10 minutes.

"Bestie. I understood it. I found out how to open it."
"Good for you."

Just as we were about to proceed, the dark elf woman spoke up,"Everybody, we have prepared dinner for you. Please follow me."

"I guess it is late. Let's continue tomorrow."
"Hai."

After that we start moving back. I turn around once and check. Yep, there is definitely something attracting me there.
