The Interlude - Ex-Demon Queen Council

Lilith and Arvis walked into a sealed room. The room they entered was a dungeon floor under the Diamond Doom. Unlike the dungeon layer that contained hundreds of doors and narrow rooms, this dungeon contained a throne room with a majestic seat in the middle.

[Headquarter of the Underground Class Maid]

In front of the throne seat that stood upright, there were 98 Maids registered in the Underground Class Maid kneeling waiting for Lilith's order. Right in front of the throne seat was a large floating mirror and displayed a special room that Hans entered.

“It's not polite, you guys observed us from the beginning?” ask Lilith.

Lilith slowly sat on the throne seat and gave a small hand gesture to pay her subordinates respect while Arvis stood beside her.

“Excuse us, H-Head Maid. It's just, we're a little curious about our new Master. Unlike previous Masters, this time we had to swear allegiance to a Player and we were uncomfortable with this change. So, to cover up this discomfort. We had to peek a little” reply one of the Underground Class Maid.

“So, how did it go? Does this one Master live up to your expectations?” ask Lilith with a smile.

“I-It's a little beyond our expectations” someone who answers Lilith's question is an old Demon who became an Undead and is known as “Ochimusha” or “Fallen Warriors”. This old demon had the physique of a young lady with a pale skin color that was filled with shards of armor around her Maid uniform. Ochimusha's figure is named Shirayuki, based on the hierarchy of the Underground Class Maid he occupies the position of supervisor of Maid duties.

“A-I didn't expect if our Master received two different contracts at the same time. I mean, bearing the burden of the Upper Class Maid and Underground Class Maid is a huge responsibility. Even our previous Master gave up and limited our movement with the outside world” Shirayuki said.

“Yes, Upper Class Maid is too looking down on Underground Class Maid!”

“Betul! If only the previous Master had not restricted our movements, it was certain that we were far superior to the Upper Class Maid. With their short lifespan, we can only wait for them to die without putting up a fight!”

“One stays! Now it's time for us to counterattack!”

Lilith heard the complaints from her subordinates and gave a small hand gesture to dampen the situation.

“The situation has changed and as you can see, our new Master does not look down on our race. Moreover, Siera has awarded the Upper Class Maid loyalty contract to our Master. Our main task right now is loyalty and devotion to the Master! We don't need to follow the path of Upper Class Maid who focused on licking the previous Master!” lilith said to dampen the mood.

“Agree!!” The Underground Class Maid had one vote for this decision.

“Fufufu... And you know what our first task is?” lilith continued with a faint smile on her face.

“Something the Upper Class Maid may not have!”

“Something that makes Underground Class Maid shine in the eyes of Master!”

“Something that makes us one step ahead of Upper Class Maid!”

That spirit-filled cheer made the contents of this room tremble. The Moral Underground Class Maid was at the highest level.

“We have to work hard to update these books!” lilith's words sounded excited and a small portal opened and took out hundreds of books that had fallen in front of the throne seat.

“Underground Class Maid gets official orders to translate these books into human language. Luckily, the language written in it is Demon language and the author of these books is among us!”

“H-Head God. Isn't this?!” Shirayuki looked surprised after seeing the books Lilith had put out tumbling down.

“You know about these books, Shirayuki?” ask Lilith.

“A-I've seen this in our royal library before. Isn't this one of the forbidden books on the creation of the Undead based on the position of the constellations?”

“Oh, you seem to know the contents of this book. Do I need to introduce the maker?”

“H-Head Maid?” Shirayuki looked puzzled by Lilith's words.

“Arvis! Isn't this one of your books? If not wrong this is a book that brings doom in the human kingdom right?” lilith said as she glanced at Arvis who was standing beside her.

“Head Maid, please don't reveal my dark past. It's true I'm the author but for that one catastrophe. You could say I'm not the culprit! I was just giving this book to a human and something like that happened. Wasn't Head Maid himself the one who gave permission to test the theory of making Undead to humans to find out the effect?” reply Arvis.

“K-Agenesis like that ever happened?” shirayuki asked with a trembling tone.

“My thoughts are a little rough about the event, if my memory is correct then this book is written based on the theory of the human soul as a magic catalyst right?” Lilith looked at Arvis and asked in a serious tone.

“The theory?” some Underground Class Maid wondered about the topic Lilith brought up.

“Human Soul Theory and Human Skeleton Catalyst as Skeleton” Monster Base Arvis said.

“Ah! I remember now! If it's not wrong we use human children who die on the battlefield as catalysts to make skeleton monsters as mine workers right?” lilith's speech sounded relaxed and caught the attention of the Underground Class Maid.

“Head Maid, keep in mind. They're not kids. In human age, age 20 years and over are not children” Arvis replied.

“Eh? But they looked innocent on the battlefield with such a move?”

“Head Maid, anyone would definitely be frightened if they saw a monster on the battlefield. Moreover, we created monsters beyond calculation with the Demon Ancient Rune. A giant monster created accidentally and managed to destroy one kingdom of humans in the past.”

“And now.there was someone who used the Demon Ancient Rune and created the same monster. The question is.. Who is this guy?” this question of Lilith created a small commotion among the Underground Class Maid.

“Seeing my work was used by others especially the ineffective use of the Demon Ancient Rune, it felt like I wanted to destroy this person” Arvis clasped his hands and tried to hold back his anger.

“Talking about your work, what is the connection between human souls and skeleton monsters using the Demon Ancient Rune?” ask Lilith to Arvis.

“Head Maid, you must not have read my book and the report I wrote, right?”

“Eh? I read it anyway. Just a small part of it, especially in the most interesting part. If not mistaken, the body of a person who had died still had soul energy left inside his body right? And the skeleton's undead creation technique required the soul energy left behind as the main fuel for its life cycle right?”

“So, that's an interesting little part? Head Maid, you must not have read the entire Demon Ancient Rune written in it”.

“Uguh! I-It took a lot of time to read all the Demon Ancient Rune that you wrote!”

“Padahan in it there are small instructions for creating skeleton monsters and skeleton age comparisons that affect their performance in undergoing complicated orders.”

“A-Arvis, do you remember how thick the book you created was?”

“Free 7,128 sheets and 331 parts attachment.”

“You know how much that is! And my main task as the Demon Queen at that time!” reply Lilith in a high tone.

“Forget that! Back to our current problem. Can this skeleton monster be defeated? I saw the Demon Ancient Rune that was used had no completion point.”

“Head Maid, based on a brief analysis found and assisted by Master Hans' knowledge. I can deduce this is a Demon Ancient Rune that is still imperfect and based on the placement of the composition of the runes it is certain that this is the Demon Ancient Rune that was used when the Ancient Rune technology was first discovered. At this stage, the main source of power comes from one's magic power being used at a certain time and the worst possibility is that this skeleton monster will continue to form until this person loses its magic source or dies. As Master Hans said, there was a possibility that this person would deliberately turn human corpses into skeleton monsters especially with the age of their bones which was fairly new. Usually, skeleton monsters are very weak with blunt force attacks due to their bones that have been brittle due to decomposition in the ground but in this case-”

“They used fresh human corpses and turned them into skeleton monsters?” Arvis' explanation was suddenly cut short by Lilith's question.

“That's right, Head Maid.”

“Can you trace the source of his power?”

“If this Demon Ancient Rune is using the latest version, we might be able to track it down. Merely, this one Ancient Rune Demon used troublesome old technology. The orders for the formation of the Undead were very simple and the movements that could be ruled were just basic command sentences like rise, attack, silence, and destruction. The main problem that we find within this Demon Ancient Rune is its main source of power. It was this Skeleton's main source of strength that gave orders to the other skeletons. Based on the skeletons we kidnap, the biggest activity they do happens at night. So, there was a chance that their Demon Ancient Rune was active at night and the position of the constellations did not affect them.”

Hearing the information Arvis gave, Lilith leaned her body on the throne seat. Deep in his brain, he thought of a situation that could have happened based on the information that Arvis had given him.

“Monster is active at night. Meaning he had plenty of free time to replenish his source of magic from early morning to late afternoon. To move a huge monster like this required a huge source of magic. A race capable of regenerating magic that is fast and has a large amount of magic is nothing but that race right?”

“Head Maid, if you think it's an Elf race. Most likely it couldn't have happened. The Demon Ancient Rune technology was only spread in our former glory era and the development of the Demon Ancient Rune for public consumption was only given a share of its magic foundation. After the ineffective research of the Demon Ancient Rune, our kingdom stopped researching it but there is someone among us who continues the research of the Demon Ancient Rune. Based on the scattered information, he conducted a small experiment in the human kingdom and used the Demon Ancient Rune series to accelerate the growth of animals and create special poisons capable of damaging vital organs. Because of the small hoopla he did, he became a fugitive of the temple and was destroyed. No more information after the news of her defeat.”

“Good information, Arvis. Perhaps Master Hans would be interested in this information. It is a pity if any Demon who understands the Demon Ancient Rune leaves our kingdom. By the way..what's his name?”

Hearing Lilith's question, Arvis held her head hair and shook her head.

“Head Maid, did you forget your granddaughter who escaped from the royal castle?”

“Eh?”

“Demon that I just told you about is none other than your own grandson.”

“EEH??!! Y-Which one?” ask Lilith.

“Haiss.. Maid Head! I know that you are a Succubus who does not care about his partner but please do not forget the descendants of your race who make offspring again of your blood.”

“How do I know such a thing right! They have grown up and left the royal castle!”

“Basic irresponsible parents” said Arvis in a cynical tone.

“Uguh! How you, Arvis!”

“Speaking about the lineage. If it is not wrong she has a daughter before leaving the royal castle.”

“My grandson has another child? Ughhhh! Why is my lineage getting longer anyway?!”

“Head Maid, sorry if this is a little rough but all your descendants are very troubled.”

“Arvis, please don't remind me of that incident.”

“Genesis about the royal coup and making Demon Queen the Head Maid of the Underground Class Maid?”

“S-It looks like you still hold a grudge with them.”

“Of course, Head Maid. Because this is my pride as the former leader of the defeated supreme forces in order to fulfill the Demon Queen's request.”

“Ehehe.. but thanks to that our work becomes relaxed right?”

“A-I can't argue with it. Working as a Maid is not bad either and a lot of free time to continue my small research that was delayed.”

“A-Anooo-eye.. Head Maid, I'm sorry if this interrupts your conversation. But, what will we do next other than translate these books into human language?” shirayuki asked who interrupted Lilith and Arvis' conversation.

“Truely too, right now we have to perfect the information from these books including the great developments that have taken place. It will make Master Hans interested in studying it as well as our golden opportunity to prove that the old Demon is not a mortal living in the shadows!”

“Then, I will try to sort out these books based on the contents of the information in them and separate the books regarding the development of the Demon Ancient Rune that created the Undead” Shirayuki replied.

“S-Please just.”

Hearing Lilith's approved command, several Underground Class Maid groups immediately gathered together and separated several books according to their expertise. The Maid who worked as an Underground Class Maid was a former loyal follower of Lilith while serving as the Demon Queen.

Arvis picks up some books studying the creation of the Undead and returns to Lilith's side.

“This feels very nostalgic. I haven't seen my hard-to-read handwriting in a long time. Thanks to that, the writing disability of the Demon Ancient Rune is clearly visible.”

“Arvis?”

“I saw that most of the Demon Ancient Rune written on the human skull had an error in its engraving. Each carving has a different symbol and meaning. Honestly speaking, this is the first time I've seen an Undead Skeleton capable of working together to form a giant skull. The main base of the magic was the creation of the Undead but with the adjustment of the Demon Ancient Rune, I did not expect that a bunch of skeletons could form a gigantic skull just from the flawed Demon Ancient Rune.”

“Are you surprised, Arvis?”

“I'm very surprised, Head Maid. Who would have thought that the flaw of the Demon Ancient Rune could create a variation of a monster like this. Apart from its troublesome control, this monster was created from the writing error of the Demon Ancient Rune. If this information is spread widely to our former empire. A war between a Demon and a human could have taken place without sending an army. Relying on the Demon Ancient Rune formula like this and taking it off at the public cemetery, it was enough to destroy a single kingdom. After all, a Demon Ancient Rune flaw like this was easily drawn by children.”

“I don't want such a thing to happen, Arvis.”

“I know, Head Maid. This information of the Demon Ancient Rune was extremely dangerous. Was Master Hans able to receive this information after knowing the great consequences?”

“If it's Master Hans, I'm sure he'll use this information as per his needs.”

“Then, I will be a little serious and do an update to these books.”

Arvis smiled and left the room.

“I'm sorry, Master Hans. Maybe the book that Master Hans will read is getting thicker” Lilith said in a low tone.

Lilith then rushed to pick up some of the remaining books and left the room. The hundred Maids inhabiting the Underground Class Maid were now busy translating books containing the Demon Ancient Rune and other important information in order to be understood by their new Master.
