Angusari, Royal Society of Magic.

The Blood Sea Demon is sealed in a giant crystal, and around the crystal is a group of royal magicians armed with various tools. The magicians looked excited, examining the demons in the crystal with the tools in their hands.

While the magicians were excitedly conducting their research, the team broke into the room where the demon was sealed.

With flowing black hair and an icy cold light shining in her azure pupils, Rhea, the Queen of the Cold Bow, walked into the room with her own personal guard.

"Her Majesty." All the mages saluted.

Queen Rhea: "How's the investigation going?" ”

The chief mage was a silver-haired half-elf aunt, and I saw the half-elf aunt step forward with an excited face and report to the queen: "Back to Your Majesty, our previous judgment was correct, this demon lord is not a clone, but an ontology!" ”

A hint of joy flashed on Queen Rhea's face: "Is it really the body?" ”

"Yes, Her Majesty."

Queen Rhea looked at the huge body in the seal, and her eyes flickered: "Bes, you come with me to the office." ”

Looking at the queen's serious expression, the half-elf aunt nodded: "Yes, Your Majesty." ”

……

In the office of the Magical Society.

Queen Rhea played with one of the talismans in her hand: "Bes, what I am going to say now, I hope you can keep it a secret." ”

"Yes, Your Majesty." The half-elf aunt bowed.

"Beth, I'm going to open up to you the real core information about Floating City."

The half-elf aunt raised her head and looked at the queen in front of her in surprise: "The real core information? Could it be that those materials in the Royal Library are fake? ”

"Nope. That information is true. But don't you think it's a bit exaggerated to use an eleven-ring spell to make a floating city core? ”

A flash of inspiration flashed in the Beth Mage's mind: "The true material of the core of the Floating City is a sealed demon lord?" ”

"What is needed is a demigod core with laws to create an infinite power source that is enough to power the Floating City." Queen Rhea said lightly, "This demigod core can be from a demigod or a demon lord. ”

The half-elf aunt looked happy: "Your Majesty, I will definitely not disappoint your expectations." ”

……

In the Royal Academy, Green is in contact with the territory.

"Felix, what do you think of this demon-summoning magic array?" Green briefly recounted the summoning of demons, and then began to ask his men for their opinions.

Hearing Green's inquiry, the fox girl was very surprised: "I don't understand the technical aspects. Master, if you have a way to control the demons, maybe this can be used as one of the territory's sources of soldiers. ”

"Hmm...... Control the demons...... It's relatively easy to control the demon's projection, but if you want to control the demon's body, it's a bit of a problem. ”

"Master, haven't you already earned the allegiance of a succubus?"

"It was an accident." Green pursed her lips, "That succubus thought I was going to kill her, so she honestly handed over her real name." If you change to other demons, even in the face of death, you will not give in easily. ”

"Then we'll just summon succubi." The fox girl had an elegant smile on her face, "I will train them to be excellent succubus maids." ”

"Haha, that's what I thought too, but I haven't found a way to summon a succubus in a stable and safe way yet." Greene paused, "How's your work going over there?" ”

"Everything is fine. The camp has been fully built, the Stormhawk has been delivered, and I've sent the letter of negotiation to the most powerful Centaur tribe in the neighborhood, the Blade Tribe. It is estimated that this winter, we should be able to establish formal diplomatic relations with them. ”

"Hmm...... Very good. Soon the academy will be on vacation, and I will go to your place to inspect the work at that time. ”

"Yes, master." The fox girl bowed respectfully.

Seeing the unmoved posture of the fox girl, Green's eyes lit up. Deception is the norm for officials, so although Felix has an attitude of "the work is going perfect", Green is not fully convinced. Can a mere "village head-level" internal affairs talent really do this kind of work well?

Green plans to take advantage of his annual leave to personally go to the front line to inspect the work. But looking at Phylix's attitude of neither humility nor arrogance, Green had a slight doubt about his judgment. Could it be that she is really doing a good job?

Never mind. In any case, you'll find out when you get to the place.

After finishing his communication with Felix, Green's second contact was with Master Harry at the Academy.

This bachelor who took the initiative to join Green, his performance was quite decent, although there were no surprising discoveries, but he was also quite capable in potion research, but summoning magic was not his field of expertise. So after some exchanges, Green was unable to get any useful advice from him.

A few hours later, Green finished his work for the day.

Green put away the communication mirror, stood up, and stood in front of the window, looking at the bustling city in the distance.

"It would be nice to get the blueprints of the floating city." Green couldn't help but sigh.

If you can get the design of the floating island, you may be able to make your own floating island operation. It's a pity that although Green knows that there is such information in the Royal Library, he does not have the confidence to sneak in and not be discovered.

……

The Royal Library contains all the important information in the kingdom, including some information on the Floating City, but it is only superficial - according to that information, the "Original Nethrel Core" (the infinite power core of the Floating City) is made using the legendary spells of the Eleventh Ring.

Spells above the Nine Rings belong to the realm of legendary spells.

The real core of the Floating City is not in the Royal Library, but in a secret repository that only the King has access to - of course, the outside world does not know this, and no one but the Queen knows that there is a secret vault hidden in addition to the Royal Library.

In the royal palace, in the Queen's study.

Queen Rhea brought Anna Beth, the chief magician of the Royal Magic Society, to her study, and in front of the chief mage, pushed open a bookcase in the study, revealing a secret room hidden behind the study.

"What is this?" Aunt Half-Elf's eyes widened.

"You are the second person to know about this secret room besides the dead Master Carolan." Queen Rhea glanced at the half-elf aunt.

The half-elf looked happy: "I will definitely live up to Your Majesty's expectations!" ”

Queen Rhea glanced at the half-elf and sighed secretly.

After the death of Master Carolan, the kingdom lost its last archmage. Tallest among the short, Anna Bes, a half-elf mage of the Six Rings, was successfully elected as the chief mage of the Royal Magic Society. Queen Rhea still trusts Anna Beth's magical abilities, but after all, she is still much worse than Master Carolan......

After signing the confidentiality agreement, Queen Rhea handed over the information to the Chief Mage.

These materials cannot be taken out of the palace, and Chief Mage Beth needs to read them in the palace and design a specific implementation plan based on them.

After getting the legendary precious information, the chief mage did not hesitate to read it all night. However, after reading the information in his hand, the chief mage was dumbfounded.

"Your Majesty, even if the improved craftsmanship is completed, you need to use the Nine Rings Spell!" The chief mage took the information and found Queen Rhea, "Unless Master Carolan is reborn, it is impossible to make it!" ”

Queen Rhea: "I want you to build on this process and simplify it. ”

The chief mage looked at Queen Rhea's serious expression and was stunned. From Queen Rhea's expression, the chief mage knew that the other party was not joking!

Queen Rhea: "Master Carolan once said that if the magic technique is used, the crafting process of the 'Endless Energy Core' can be simplified to the extent that even the six ring mages can complete it. ”

“！！！” The Chief Mage's eyes widened. The difference between the sixth ring and the ninth ring is huge!

"Since there was no demigod core in the first place, Master Carolan did not conduct this research. Now, I need you to reopen this research and work it out! ”
