There is a building with white wall that looks like a research facility on the other side of the battlefield.
Barbed wire are furnished on top of the two-meter high fence which would have prompted Arisa to say, "I'm losing the fantasy-feeling", if she were here.
It seemed Semeri had free pass, we greeted the mummies who were guarding the gate without being stopped and entered the building.
I thought the building was made from marble when I saw it from afar, but I see that it's made from concrete when I look close.
We go forward in the building while being guided by the skeleton who welcomed us.
I decided to act as if I never saw the skeleton who was wearing maid uniform.
We're led to an around-50-tatami wide room that's illuminated by fluorescent lamp-like light.
There's a big table in the center, and miniature tanks and golems have been placed on the diorama that's modeled after the battlefield earlier.
There are a mummy and a full-body armor doing some kind of verbal warfare between that table.
I understand that those two are the [King Mummy] Tetsuo, and the [Iron Stalker] Takeru from AR indicator.
"Muu, Semeri huh. Did you come here to ask for a tank to fight Ban?"
"I'll especially design a reinforced one if ya let me massage those lump of fat that aren't put to use for one hour, how bout it?"
"Y-you perverted gramps! How're you going to take responsibility if I get hated by Ban-sama for bringing such a boorish thing like a tank!"
Corpse and Armor are about to escape from Semeri who's raised her arms with a face reddened from their sexual-harassment remarks.
It's not my imagination, they look to be some fun people. However, their mind seem to be like a primary schooler.
After thoroughly playing around with Semeri, the two who finally noticed me asked my identity.
"By the way, who's the guy over there?"
"Is he Semeri's, this?"
Armor makes an indecent sign with his finger, and then his helmet falls down to the floor after getting hit by Semeri.
The inside really is hollow huh.
"Nice too meet you, my name is Kuro. Coming from the same place as Ban-dono--A 『Japanese』, did that come through?"
"Nuu? A black haired 『Japanese』 despite not being a hero?"
"Did you come looking for immortal body at that age? Go enjoy your life for another 30 years first."
"That's right, don't be like this machine body of mine. With this metal armor body, even rubbing Semeri's breasts won't feel fun ya know?"
"My breasts belong to Ban-sama!"
They're even noisy while greeting people.
However, just like Ban, I don't feel any malice from them even though they look like they can become the last boss.
Particularly Corpse, I would have thought he was a monster and exterminated him if I didn't meet No Life King Zen before.
--But well, they would have long been defeated or became demon lords and killed by the hero if they were quick tempered or people who could easily make enemies.
"So, what's your business? Or do you really wish for immortal body?"
"No, I had asked Semeri to guide me in the lower-layer sightseeing tour, so I was brought here since this was the most interesting one."
"Ha? Tour?"
"Uhyo hyo hyo, first time I meet someone whimsical enough to come to this hell's pot for such a reason."
They greatly laughed when I told them my business.
"Well alright. For the past thousand year here, there were only guys with dazzling wish like wanting an immortal body, or the lost knowledge."
"And the rest were 『Heroes』 who mistook us as demon lords, coming here to subjugate us but got killed themselves instead."
I can't read their expression at all, but I can feel that they're fed up.
For the time being, since they had welcomed me, I presented them powder-type cannons and muskets, that were only good as fertilizers for my storage.
I was worried whether the Item Box could take out the cannons, but the Item Box's entrance changed for an instant when I tried taking it out, and I was able to pull it out.
"Oh, that's rare."
"This one is a cannon I designed when I was at Furu empire. Slimes that could absorb magic were multiplying greatly, so I designed this to exterminate them."
So Armor-shi was an engineer of Furu empire huh.
It was the empire that the Wild Boar King destroyed if I'm not mistaken.
The souvenirs were more popular than I thought they'd be, so they're going to let me tour the museums that are located in the closed space.

Corpse dive to a golden door that's floating in mid-air without any support.
It seems to be a teleport door, Corpse's luminous point in the map and radar has disappeared.
When I search for him in the marker list, his location is displayed as [UNKNOWN].
I try to use [Clairvoyance] magic, but there is no effect like when I tried to peek at True Ancestor's castle.
Following Armor and Semeri, I dive into the golden door.
When I check the map, it displays, [Area without Map].
I've seen this before--right, it was like this too when I was trapped inside Zen's shadow.
The inside is a vast white world that continues on forever.
Numerous cuboid-shaped 50-meter high buildings are standing at fixed intervals.
"Is this place created with space magic?"
"No, this space is created by Yuika's unique skill for me. We don't have to worry about gods peeking at us here you see."
I imagine god have the job of peeking at the lower world from above the cloud.
Oops, I have something else to confirm before that.
"By the way, is this person called Yuika a reincarnated person too?"
"Yea, that's right. However, unlike me, Yuika is not a human, but born as a 『Little Oni-Kin (Goblin)』. Afraid of other people after having through some terrible things, Yuika stayed hidden indoor in the domain they created themselves."
