Locke was slightly stunned, then pushed a cup of witch tomato juice that Lady Irina had ordered for him back in front of Lady Irina. "Senior Irina, please, can you tell me how to crack the Nigervold Astrology System?"

Lady Irina looked at the witch tomato juice she had paid for, being pushed back in front of her by Locke to reward her, and couldn't help but feel amused.

She laughed a few times, and their relationship became further harmonious.

Only people of the same status could joke around.

And being able to joke was a key signal of deepening relationships.

It was also a method to quickly draw closer.

Of course, this depended on what class you were and what class the other person was before using this method. Otherwise, actively joking might be viewed by the other party as a provocation.

Lady Irina shook her head helplessly and smiled at Locke. "Using something I bought to reward me, only you could do that, Locke. But that's fine. I was originally worried your personality was very serious, so I was being somewhat constrained in my speech."

"But I didn't expect that the Eye Demon wizard with such a fierce reputation would actually have quite a lively personality."

Locke said, "Senior Irina, those are all misunderstandings about me from the outside world."

"They're all stereotypes."

Lady Irina nodded in agreement, finding it very reasonable. "Indeed it is. Actually, among my fellow disciples, my personality has always been relatively lively, and I like cooperating with people and relying on those capable seniors. Oh, now there's also a genius junior like you."

"But because I always put on a stern face in front of those students, many people have misunderstood me." Lady Irina sighed regretfully. "Actually, I'm only in my fifties. For a formal wizard, I'm in my prime years and quite young."

Lady Irina said, "But I can't really mix with those students."

"So I just have to let them continue misunderstanding me."

Locke nodded. "It's fine. As long as our friends know what kind of person you are."

Lady Irina said, "Back to the topic."

"Locke, the name Nigervold, when transliterated and translated using several magical languages of the divination school, means citizens of the fog nation. This system is built on the corpse of a world serpent from a small to medium-scale world that the southeastern quadrant's White Wizard Association conquered in earlier years."

"That world serpent was a wondrous serpent coiled around that small to medium-scale world. The residents of that world lived on it and called themselves children of the fog."

"The White Wizard Association named that serpent the Fog Nation Giant Serpent."

Lady Irina said, "The Nigervold Astrology System's functions are very powerful. Actually, even if you leave the southeastern quadrant and go to a nearby wizard land, you might still be able to use this system. The association prohibits it only because they're afraid of causing disputes from other wizard lands."

"But in fact, First Circle wizards who secretly crack the system and use it covertly in neighboring wizard lands are, as far as I know, not few. The association is also fully aware of this but just doesn't pursue it too seriously. As long as you're not caught, nothing will happen. But if you are caught, things will become very troublesome."

Lady Irina blinked. "So this information I'm telling you, you'd better not spread it around. It won't do you any good, Junior."

"You just need to pretend you don't know anything."

Locke suddenly understood. "I see."

Didn't that mean the Nigervold Astrology System was built on a small to medium-scale world?

No wonder this system was so powerful, able to use divination magic to connect most First Circle wizards within the southeastern quadrant.

Lady Irina said, "There are many research groups responsible for the Nigervold Astrology System, with complex member structures, so many loopholes are left. But to modify from within the system requires finding excellent divination school wizards."

"That requires paying relatively high costs, and it's also easy to be discovered. So aside from wizards within their divination school, basically no one does this."

"There are always more solutions than problems." Lady Irina took out a set of soft invisibility cloaks from her astral ring. "I have a shop that specifically sells 'gray' items, which sells special magic tools to solve this problem."

Lady Irina pointed to the silvery-gray invisibility cloak on the table and said to Locke, "This is a permanent invisibility cloak, a First Circle enchanted item, a magic tool."

"Alchemists made it from the feathers of invisibility birds. The key point is that it's plated with a layer of alchemical material called Number 81 Absorption Film."

"I've forgotten the specific academic name. Anyway, it's a type of alchemical material that First Circle formal alchemists specifically developed to evade the restrictions of the Nigervold Astrology System."

"You know this, right? Alchemy is about changing material substances, creating new magical materials by adjusting elemental particle arrangements, combining different grades of magical materials, or through other methods."

"Magical alloys are just the simplest among them, but they're also mainstream in alchemy. Therefore, the main energy at the alchemy assistant stage is spent researching magical alloys."

"At the First Circle level, formal alchemists, besides developing better magical alloys, also develop new magical materials, such as special films, special metals, high-energy polymers, and so on."

"Of course, I don't understand these things either. I just manage over a dozen alchemy workshops." Lady Irina said, "If you wear this magic tool invisibility cloak that's been secretly plated with Number 81 special film, the Nigervold Astrology System can't confirm your location."

"The Nigervold Astrology System confirms your approximate location, not specific location, just a very broad approximate location, by detecting when you activate the system and release slight magical fluctuations, then through magical fluctuation feedback, confirming whether you're still in the southeastern quadrant."

"But as long as you wear this invisibility cloak, the film on the cloak will absorb the slight magical fluctuations you emit when activating the system. The Nigervold Astrology System can't confirm your location, and then you can use it in other wizard lands."

Lady Irina said, "This system is still quite useful, so why not use it if you can?"

"Wearing this invisibility cloak, the Nigervold Astrology System can't see your location. Then, unless you go to the extreme limit of this system's actual communication range, you can use this system."

"This invisibility cloak, I'll give it to you." Lady Irina said, "The invisibility cloak itself isn't valuable, only worth about one thousand magic stones, because the invisibility magic enchanted and solidified on it is very ordinary, shoddily made. It's basically impossible to deceive anyone at the First Circle wizard stage, so the price can't be measured by normal magic tools."

"What's valuable is the Number 81 absorption film on it. In my shop, selling one of these invisibility cloaks for ten thousand magic stones is very normal."

Locke raised his eyebrows. He hadn't expected the selling price of this gray item could be so outrageous.

He also understood why Lady Irina didn't understand alchemy deeply.

Because the magical field had developed to this point and had become extremely vast and profound.

For example, just potionology alone had dozens of branches, with even more small branches beneath.

Actually, breeding was the same. Some breeding wizards only specialized in researching a small classification of magical plants. There were hundreds of such classifications.

Every year, new sub-disciplines were born in these two fields, and new revolutionary theories appeared.

The magical field was so vast, like an ocean, inexhaustible.

Like truth itself.

In this era when wizard civilization was at its peak, all-rounders were already impossible, and also inadvisable and unnecessary.

If a person learned knowledge from so many parallel fields, it would be a waste of time. So it was very normal for Lady Irina to not understand the alchemist field well.

Locke also just learned about the basic knowledge of other fields from the Universal Course and reading some popular science magazines and articles in his spare time.

Currently, he was already researching four fields: botany, breeding, potionology, and archaeology. The knowledge systems of all four fields were interconnected. Even with the Synthesis Cube simplifying the learning difficulty for him, there was no need to add new fields of study.

At least for now, there wasn't this need.

Anyway, even if he needed knowledge from other disciplines, he could find wizards from the Universal School, which was the true all-rounder cultivation direction of wizards in this era.

From them, he could learn which particular section of articles he currently needed and have them recommend some reading lists.

And if he just needed some items, he could just buy them directly.

Locke accepted the invisibility cloak. Since Lady Irina wanted to give it to him, he had no reason to refuse. "Senior, thank you very much."

Lady Irina smiled slightly. "In the future, we can stay in touch more on the gray mist stone tablet."
