Chapter 193

Everyone laughed, and Sylas laughed along. She could grasp the comedic irony of the story, mocking the shrewdness of merchants and the vulnerability of human hearts. However, she didn’t have any profound understanding of the shrewdness of merchants.

"Jane, what questions do you have?"

"Who is this mysterious young person that sounds impressive? Did anything relevant happen afterwards? Did you keep her as a teaching assistant or a partner?"

Eilan smiled and said, "Yes, her graduation thesis was about some issues regarding contract spells, and she even quantified the intensity of contract spells. Speaking of which, I want to mention the concept of ‘submersion depth.’ Now, here’s a question: When you summon the water lord, do you notice any sentences that control its intensity?"

Caroline asked, "Are you referring to the sentence, ‘I earnestly request’?"

"No, not that one."

"Is it about the sentence, ‘My magical powers delve into the depths of the infinite waters’?"

Eilan nodded with satisfaction, but her voice was always soft and gentle. "Very right, Sylas. Why did you think of that sentence?"

Sylas smiled shyly and said, "I seem to have seen it somewhere, in a research paper about covenant spells. All the covenant spells mentioned there had similar frameworks, but this sentence is different from the frameworks of other spells. It also seems to be related to the ‘depth’ you mentioned earlier."

"Very good, the well-deserved ‘little fairy’, hmm?" Sylas blushed as soon as she heard it. She didn’t expect that nickname to have reached the teacher, but Eilan completely ignored her reaction and continued, "That’s right, ‘submersion depth’ is a concept proposed by my mysterious student. We use it specifically to describe the intensity of mind-based spells. Its original meaning refers to the depth to which the spell caster plunges into the recipient’s mind. The greater the submersion depth, the greater the intensity of the spell. I don’t need to explain the intensity of spells, right? But to ensure the quality of the class, I still need someone to answer. Any volunteers? Viniol?"

He is a boy with dark skin. Sylas remembers him, they were comrades who fought against Sauran together. When there was an incident in Sauran’s classroom, he was sitting in front of Sylas.

"Spell intensity is the measurement of the damage caused by a spell to the target."

"Very good, this is a basic concept, I believe you all remember it well. The quantification of spell intensity had a major breakthrough about forty years ago, and the most important, and probably most hated, formula is the Emerson equation. His students dedicated themselves to this kind of work, and I believe you can also mention some other formulas and people that you’ve long hated, of course, most of them being his students or partners of his students."

The students burst into laughter, yes, everyone hated them during exams.

"Sylas, what’s wrong? You have a serious expression." Yes, everyone was laughing, only she stood there in a trance.

Sylas blushed and smiled, saying, "I know who this mysterious student is."

Luna and Jane were so eager to pounce on her, asking, "Who is it? Who is it?"

Eilan sat down and told her, "I’m very interested to hear your answer."

"It’s Xerath."

"The answer impressed me, but she was right. Xerath inspired my research. Later, I even went to listen to her graduation defense. It was an excellent paper. If she had delved deeper, it could have even been considered an award-worthy thesis. Of course, she eventually became an archmage with a different paper. Based on her work, I conducted further research on demon spells, which was then accepted and continued by many others. The mainstream academic community recognized the research on demon spells largely because of Xerath."

Sylas suddenly understood why Sauran always said Eilan favored Xerath.

"Alright, time for this class is almost up. The only things I want you to remember are these few points."

The chalk fairy automatically wrote on the blackboard, "Demon spells belong to the category of mind magic, which falls under covenant spells."

"And finally, this formula for diving depth, remember it well, it will definitely be on the test." The chalk added the sentence "it will definitely be on the test." The formula for diving depth looks similar to the spell intensity formula, but the ranges for some values are narrower. Since this is an elective course, Eilan only introduced relevant research papers for students who want to further explore the topic.

Before announcing the end of class, Eilan waved to the last row and Kuowa spread her wings. Like a bat, she flew towards Eilan. Eilan seemed used to it, extending her arms to embrace Kuowa. Kuowa appeared delighted, smiling contentedly, and her black tail swayed from beneath her cloak.

Eilan gently turned her face towards Kuowa, and Kuowa obediently extended a finger to push Eilan’s glasses back into place. Eilan then said, matter-of-factly, "Kuowa is my contracted demon. In this classroom, she can use magic to deceive you. So, my final request is: don’t believe anything the demon says in this class, or else you will pay the price for trusting a demon. Alright, class dismissed."

One by one, everyone walked out of the small classroom. Luna patted her chest and exclaimed, "Oh my, oh my, I finally understand the beauty of being a woman."

Jane also said with lingering fear, "I think I’m about to fall into a trap."

Sylas asked strangely, "A pit? What pit?"

Jane quickly shook her head and said, "No, I mean I understand why Eilan doesn’t want Kuowa to be in front of the classroom. She’s not interested in learning at all."

"Demons are really scary, but," Swis chimed in, "it’s still tempting to get fooled!"

Caroline said, "You know what? People like you are the kind that demons love to tempt the most."

Sylas said, "With you saying that, we might never be able to measure the earth’s veins near Mount Borliboli."

"Are we really going?"

"Hmm… even if we don’t measure, we should still go nearby and ask. It’ll take at least half a day to measure the earth’s veins, right? During this half day, it’s impossible to not have any interactions with people in nearby villages because you need to restock on food and fresh water. Sometimes, you even need a local guide. Their measurement times vary, so naturally, the time it takes to reach the village will be different too. It would be even better to ask if there are no travelers nearby."

"So, when do we leave?" Swis asked.

Luna suddenly said, "I have something to take care of. Just let me know the time after you’ve decided. I’ll leave first!"

After speaking, she took Jane and appeared about ten yards away.

"You run really fast…" Swis complimented.

The two of them walked out of the school campus, excitedly hugged each other and danced the fandango. Jane whispered with excitement, "Real life is a hundred times more interesting than fiction!"

"I want to go buy it!"

As they spoke, the two of them hand in hand went to Fenika’s bookstore. At this time, there weren’t many people in the room. Jane dashed towards the counter where derivative novels were placed (usually some unpublished hand-copied books, very precious). She took out a book and ran towards Fenika, saying excitedly, "I want to dive into this pit!"

Fenika was still within the range of the silencing curse, furrowing her brows and looking at her.

Luna also squeezed in and wrote on a blank paper, saying, "Today we attended Eilan’s class."

Fenika smiled and asked, "How was it?"

Jane was so elated that she wanted to talk to her, but in the end she had to calm down a bit. She wrote with a pen, "The gorgeous demon and the serious mentor are so adorable. Kuowa was ordered by Eilan to sit in the last row of the classroom, but Kuowa always finds ways to tease Eilan. Today, she threw a heart from the back row to Eilan. What kind of spell was that?"

Fenika said, "I heard it’s a kind of magic spell. What about Eilan?"

"She accepted the demon’s teasing without showing any emotion."

Fenika giggled and said, "If you want to buy it, make sure to carefully read the setting in front. Don’t blame me later for not explaining clearly. You can also finish reading it now. Okay, now I can hear again."

Luna quickly opened the book, and on the first page it said:

Demon spells are mainly used to tempt other creatures. Fragile humans are usually no match for them. Even mighty dragons can fall for their tricks. However, there is always a special group of brave individuals in the world with a strong will. They challenge demons and investigate demon cases. They are called the Ninth Investigative Team.

Demons offer various temptations to humans in exchange for what they want. Afterwards, they often deny and refuse to fulfill their promises. The only way to resist demons is to not believe any of their sweet words. But the harder it is to deceive someone, the more precious they become in the eyes of demons.

Kuowa, the demon known for her expertise in seduction, sees Eilan as her most important prey in her lifetime. Her lifelong wish is to deceive Eilan’s love and then trample on it.

"Uh… I didn’t see this page before."

"Have you read it now? Are you still deciding to continue?"

"Are you saying… that the fight between Eilan and Kuowa was just a long-lasting battle? And that all of this was a trap set by Kuowa for Eilan? There was actually nothing between them…?"

"If you’re asking about the characters in the story, I can tell you this: It’s not just that. If it were real people," Fenika shrugged, "I write my stories without any relation to real people. I just found their interaction interesting, so I based a story on it."

Jane clenched her teeth and said, "I’ll buy it! Do you want to read the same book with me?"

Fenika suggested, "Handwritten copies are expensive, even if they’re written by the Water Lord, but…"
