Only then was it apparent that there was a body of deadly gas, faint purple in colour, floating in the air.
Yuri looked around to find the source of the purple gas. However, neither the ceiling, walls, or corners had anything emitting that purple cloud.
As a look of confusion surfaced on Yuri’s face, a monotone voice spoke up.
“………Yuri-nee, there is toxic magic in the air.”
“What?”
Yuri felt a cold glance in her direction. The source was Shizu’s calm green pupil; an eye which harboured no emotion.
A better way to put it would be that it induced others to believe it was incapable of feeling emotion. Shizu’s facial features were delicate, but in another sense it was also like a mask.
Because she was created as an automaton, Shizu could not display emotions – such was her settings.
“……Blood of Jormungandr?”
After Shizu revealed the name of this tool capable of creating such a toxic zone, Ainz replied:
“Ah, correct answer. Although I have not informed you, this treasure renders the surrounding air highly toxic. If you did not possess any abilities or tools capable of countering this toxicity, you would have dropped dead within three steps.”
“So, is that why I …apologies… is that why we three were selected?”
“Correct.”
Both the dullahan Yuri who was adjusting her glasses and the emotionless automaton Shizu were immune to toxins because of their racial traits.
Albedo belonged to the demonic race and was not immune to toxins. However, she had an alternative way of dealing with toxins.
“Correct, that is the reason all of you were brought here, but… I brought Shizu along for another reason to confirm something.”
Thus Ainz and the others used 「Mass Fly」to bypass the effort needed to cross the gold mountain, and arrived in front of a door on the other side.
No, could it really be called a door? It was in the shape of a door, but looked like a bottomless pit attached to the wall.
Arriving at this picturesque door, Ainz was deep in thought.
“This here is the armoury, what was the password again…?”
“Ainz-sama, if there is an armoury, does it mean that there are treasures concealed in other locations?”
Ainz was puzzled over why Albedo would ask such a question. Nonetheless, even if she was unaware of such information, it still made sense. The treasures were not housed inside the Great Tomb of Nazarick. It was necessary to use a ring of Ainz Ooal Gown to be transported to that location. It was designed in such a way to make an invasion extremely difficult. It was normal for Albedo to be oblivious of this information, since she didn't have her own ring just ten days ago.
Although Ainz somewhat wondered just how much knowledge the NPCs possessed, he felt it was a trivial problem and replied to the earlier question.
“Ha ha. I had a comrade by the name of Genjiro. He took pleasure in keeping things neat and organised, and should have categorised objects according to their purpose.”
“Wasn’t he the Supreme Being who created our companion Entoma?”
“Yes, Yuri you are correct. However, whether he actually relishes tidiness may be questionable. If he truly did, the treasures in that gold mountain would be managed more orderly, and he would not describe his own room as a mess. Speaking of which, he should have already separated the items into categories: armours, weapons, jewelry, auxiliary tools, consumables, manufacturing goods, etc. In addition, there is also the Nazarick maintenance room… yes, and also the crystal data storage room.”
During this rant, Ainz’ finger was pointed towards the wall, where a two-dimensional shadow had appeared.
“However, in reality the inside is connected so it shouldn’t matter which way we enter… Ah, sorry. I have talked too much.”
“Not at all, we are grateful towards Ainz-sama for answering our questions so passionately.”
Following Albedo’s statement, the two battle maids simultaneously bowed to express their gratitude.
Ainz shrugged, then turned again to face the shadow in front of him.
This door could only be opened by a predetermined password. Perhaps with magic or a skill from the rogue class, one could force this door open. But Ainz had never learnt such magic or skill, therefore, it was necessary to speak the password…
This is understandable.
As such mechanisms were plentiful in Nazarick, it was possible to remember passwords for the place one visits frequently, but there weren’t many opportunities to visit the Treasure Hall, so it was impossible to remember the password for such a place.
