After hidden doors, many tricks, Yoonada reaches the underfloor door that was in a hidden room. The door is sturdy because it is made of steel. But that's a general point of view, and it's no obstacle to the three of us.

"Good!

- Baki, baki, baki, baki!

It was supposed to be heavy. It was pulled (squeaked) with the loose hanging noise between Yuna, and it was easily destroyed. No matter how the steel door closes its path, if it is broken through with pure physics, the key does not make sense. The iron door is peeled off with it, and thrown down on Dogan and his neighborhood.

"Looks like it leads underground on the ladder. Suspicious to see... it's dark. I can't see ahead."

"Tsukayuna, you know this place well?

"As I said earlier, I was talking about Mr. Bigger's previous workplace, and there was something similar about this place. I was stunned (surprised) too because it was all the same way to go and hide it!

"Previous workplace, hey"

"Maybe, but didn't Mr. Bigger tell Yona an old story in anticipation of this development? Looks like Mr. Bigger's gang is leaving Elderado. Even if it was a trap, we'd be looking for it all anyway. Don't be afraid to go."

They agreed with Chinatsu's words and nodded deeply at each other.

"Copy that. I'll run the fume fog gas through this entrance again."

"Oh, before you do, it's a hassle to carry a Kira trapped in Chinatsu's barrier, and let's poke this guy down first. Go."

The knife, the immobile killer, kicks down into the pitch black that spreads underground.

■■■―――

His screams go away step by step. The three of us then confirm the small falling noise. Apparently this basement is pretty deep.

"... seven to eight seconds until it crashes into the ground, I wonder from something like that?

"Well, that sounds deep."

"I don't know the exact distance, but it sounds pretty deep"

"It's about three hundred meters. Considering it's the height of the Tokyo Tower, I think it fits pretty well."

"" It's deep ""

"It'll take a while to get down that distance on the ladder, and it sounds like you should jump directly. Besides, I think it would be more fun."

"" Chi, Chinatsu?

Screaming madness, again. After that, Yona, who regained her mind, magically produced poison gas, releasing this underground as much as she did in the castle. About three minutes later, Yuna signed the OK.

"Pass on the magic of the flushed poison gas and somehow the mapping is complete! All the way down, it looks like it's a maze aisle. There were several roads where the poison gas was blocked along the way, so maybe that's the route that leads to where it matters."

"Shut it off... like a submarine waterproof door, you must have detected poison gas and prevented it from breaking in."

"Whoa! I mean, there's someone ahead, right? Good luck, you're a safe house!

Well, I'll be the lead first.

"Oh, wait a minute. 'Cause the magic of Daylight ensures brightness first."

Luminous Magic Level 20, "Daylight," is the magic that illuminates the surroundings of the subject. When Chinatsu chanted that spell, the surroundings of the three became moderately bright.

"Good vision! Thank you, Chinatsu!

"Whoa! Do you want to go with the second big descent today!

"Right. Enjoy the momentary movement. Huhuhuhu."

………

To be honest, it was Yuna and the knife that I think scares Chinatsu with a smile.

Deep inside the underground facility of the castle, there exists a laboratory headed by 'General of Drugs' Obe, but this place is only known to a limited number of people, even within Elderado. Because this facility, which houses the monsters captured by Elderado and the enslaved translations, by its outrageous nature, does not exist ostensibly. There is no ethics in this place with chimeratization in formulations to create illegal human experiments and powerful monsters. All to make a strong soldier - just for that, Obe was allowed to do all kinds of research.

"Gi, gi..."

"Grrrrrrrr"

A floor lined with custom cages, the smell of the beast fills the neighborhood, and the creepy sounds of the beasts are heard from there. Overseer Obe was looking up at a large cage in the corner of this space. I'm gazing into its contents precisely, but I can't hear anything from the wonder and its cage.

"Hiccup, how many years has it been since you were transported here? I've spent a lot of time researching things, but there's no other guinea pig like you who's motivated me to do it."

………

"Yes? Maybe you're in a bad mood? Because I was about to cheat on Acerola? No, no, no, that's a pretty misunderstanding. Such an asshole, I really can't be there sometimes. [M] It's a kind of lost, lost mind."

………

The contents of the words are as horns, and Obe continues to speak seriously to someone in the cage. But there was never a response, only Obe's solitary words echoed around. Obe tries to spin the words too, but the warning noise stops as he suddenly begins to sound his mouth.

"The D-5 block entrance has been destroyed. Estimate this as an intruder and perform a blockade on each passage. Follow presets to unlock reinforcements and fusion monsters on each block. Staff in the facility should be evacuated immediately. I repeat: the staff in the facility immediately - '

Such warning audio rang along with a shitty siren.

"Looks like you found your way into the basement. Should we assume that everything on the ground, including General Zulu, has already been suppressed? Still, it's a lot faster than the calculation. Damn, are the other incompetents willing to protect the country? Or was the enemy stronger than that?

With a deliberate sigh, Obe began to operate the console that was nearby.

"But it's not that easy to attack your research facility. Reinforced humans who unlock human body limiters in exchange for lifespan are hardening their bodies with the latest equipment. Some of them are poison resistant masks, so even good poison works well."

- Zune...!

"Oh, yeah, yeah. The fusion monster that I made so thoroughly, the so-called chimera, is confident, too, huh? Scratch the strengths of the creature and chop them up. We only sorted out the strong ones who won by fighting each other. We'll have trouble having them with the mass-produced demon kings around here. Oh, trouble!"

- D'Gorn!

"Soldiers and monsters who protect the lab are not the only threats. This lab itself has a trick in place to get rid of the outside enemy. It is possible to release your best poison gas from the blockade of the aisle, flush instant electric shocks across the aisle, or turn it into an oven for each floor. No matter how good it is as an individual, you are not allowed to do so. Hi-ha-hi-ha-hi-ha."

- Darn! Barn!

"Hmm? About half the defenses are broken, huh? No, no, you just tested it in the morning. This is a thousand meters underground, isn't it? I just broke in through the entrance, and that's what happened in this moment... but I can hear it coming from above just now, this sound haha -"

- Dogaraan!

Suddenly, some of the ceilings on the floor where Obe was were destroyed with explosions, no, and roars. After that momentum, dust rolls up all over the floor.

"Successful penetration for shortcuts! And we get to what looks like it!

………

Lovely, and full of energy. Someone came down more than a hole in the ceiling. Even the chatty obe couldn't block his open mouth all this time.

"Ah, I discovered someone who seemed to know everything. Can I ask you a few questions about the road?

When the dust stopped, a girl with a vicious-sized black wand on her shoulder appeared smiling more than in it.
