The villainous young master just wants to live a Buddhist-like life.

　Professor Kazel said, "But what I find strange is that his mind is not being controlled, as if some kind of pure dark power is awakening within him. Although it has some effect on his sanity, it is not to the point of demonization."

　Professor Sylph frowned and asked, "So is it good or bad?"

　"It's a mixed bag," Professor Cazell said. "Perhaps we should go and discuss it with Ophelia."

　Upon hearing this, Dark was filled with doubt.

　If you told him directly that the Demon King had been reborn in Vittor God's body, he wouldn't be so curious.

　But now, I can't help but want to uncover its secrets.

　"So, does that mean Vittor's basic understanding of the 'Cerebrolysmic Demon' is also based on the influence of that dark attribute power? Because it hasn't gained dominance, nor has it been invaded by anything, his knowledge is only superficial?"

　……

　This investigation has brought them to the attention of many things they wouldn't normally notice. However, their initial objective has not yet been achieved.

　After summoning and questioning several spies in succession, it was finally Cameron Maysfield's turn in fourth grade.

　Cameron Maysfield possessed extremely advanced mental magic, and his mind was greatly disturbed when Professor Cazell mentioned that Fern Morse might become an idiot due to the implantation of the "Brain Fluid Demon".

　Therefore, it is highly likely that he is a person with connections.

　After he was summoned, Professor Cazell questioned him further.

　Listening closely, Dak realized that Cameron Maysfield was not familiar with Fern Morse.

　The reason he was excited about Fern Morse potentially becoming an idiot was because he knew about the "Cerebrolysm" and how the "Cerebrolysm" was created!

　Under Professor Cazell's relentless questioning, Cameron Maysfield finally succumbed to the mental torment and confessed his mistake.

　"I found a book at the beginning of the school year in September."

　He said it with a very regretful tone.

　"The book contains numerous methods for cultivating special demons, including the method for cultivating 'brain fluid demons.'"

　"In order to study the targeted transmutation of those special demon races and thus create corresponding magical spirit cards, I began to try to cultivate them."

Chapter 676 Request for Subscription: Darkdemon Returns to the Starting Point

　Cameron Maysfield was a very low-key person and rarely appeared on the public dueling stage from his first to fourth year of high school.

　But he was indeed outstanding, so much so that he gradually gained fame despite his shortcomings.

　If he can graduate smoothly from St. Marian Academy, he will most likely become a research-oriented mage.

　Of course, this is not actually consistent with his identity as a member of the Knights of the High Priests.

　But Cameron Maysfield's courage may well manifest itself in other ways, such as... research?

　He was quite audacious to pick up a book whose author he had no idea who wrote and then proceed to cultivate demons according to its contents.

　After listening, the professors looked at each other in bewilderment.

　But Professor Cazell suddenly asked, "Then, what about that book?"

　Suddenly realizing something, Dak looked at Cameron Maysfield with a slightly strange expression.

　Immediately afterwards, he heard Cameron Maysfield say, bowing his head, "Gone."

　"Gone? Can a book grow wings?" Professor Lily said with a grin, propping her chin on her hand.

　Cameron Maysfield looked ashen-faced.

　Although he himself was unwilling to believe it, the book he had inexplicably found had indeed vanished.

　Moreover, he didn't actually gain anything from it.

　Professor Cazell shook his head and sighed, "Not only did he fly away, but he also didn't achieve any results in his research. That 'Cerebrolysmic Demon' wasn't even cultivated by him."

　Professor Lily's eyes lit up, and she clapped her hands, saying, "I get it! It's all for naught!"

　Cameron Maysfield lowered his head even further.

　But Professor Sylph frowned and said, "If he didn't cultivate it, then what is he regretting? Is he regretting that the book ran away before he could produce any results?"

　Professor Cazell looked at Cameron and said, "That's a question for him to answer."

　Cameron Maysfield almost buried his head under the stool.

　But to be honest, he did have that thought...

　Under Professor Sylph's intense scrutiny, Cameron Maysfield forced himself to speak: "In fact, my experiment ended in failure after only half a month. Most of the knowledge gained from the book disappeared with its vanishing, and even the content copied into the notebook lost its core. The same was true for the research on the 'Cerebrolysmic Demon.'"

　"But I thought that once it disappeared, it would never reappear. I never expected that after more than two months, the 'Brain Fluid Demon' would actually be cultivated and even harm Senior Fern Morse."

　"I'm so sorry I didn't report this to the professors right away!"

　……

　Professor Sylph, however, was slightly displeased: "Since you didn't do this, and you didn't write that book, what's the point of apologizing? Why not think about where that book came from and where it most likely went? Besides, doesn't it have a title?"

　Cameron Maysfield hesitated for a moment, then shook his head and said, "I don't remember."

　Professor Sylph frowned. "Even the memories associated with the book's title have vanished along with the book itself? What else do you remember that allows you to trace its origins?"

　Cameron Maysfield pondered for a moment, then his eyes lit up, and he said, "I remember now, it's not printed! It must be handwritten!"

　Professor Sylph and Professor Cazell exchanged a glance and whispered, "Very good, this information is crucial. Can you then deduce the specific date the book was written? Perhaps there are some unique features in its handwriting or font?"

　Cameron Maysfield frowned for a moment, then shook his head and said, "Although it looks like a modern script, it could also be that it was set up that way, and everyone sees the most familiar characters."

　Professor Sylph nodded slightly and said, "Since it can erase the key traces of its own existence, it must possess extraordinary power. Perhaps it is some kind of creature itself."

　At this point, her eyes flickered slightly as she thought of a special kind of demon—the "Book-Eating Demon"!

　The "Book-Eating Demon" feeds on books. If the book it eats is a unique copy or original, it can completely erase the unique knowledge within it from photocopying, reproduction, thought processes, and so on.

　The observed phenomenon is exactly the same as that described in Cameron Maysfield's book!

　……

　After questioning him for about fifteen minutes, Professor Sylph released him after instructing Cameron Maysfield not to reveal the information.

　The professors then looked at each other and began to discuss it.

　Professor Sylph said in a deep voice, "That book is very likely made from the skin of a 'Book Eater' or a 'Book Eater'."

　Professor Kazel stated, "But like the 'Mind Demon' and the 'Brain Fluid Demon,' the 'Book Eater' is theoretically an extinct demon race."

　Professor Sylph said, "Since the writer even knows the method of cultivating 'Brain Fluid Demons,' it's not surprising that they could cultivate new 'Book-Eating Demons.'"

　Dak put down his pen and said to his notebook, "Let me summarize briefly. Based on the information we have, Cameron Maysfield found the book in a window near Lovers' Bridge on September 3rd, the first day of school. He stayed there for a while, but when he didn't see the owner, he took the book back to his dormitory, intending to hand it over to the professor the next day."

　"But after bringing the book back, he idly flipped through it and became completely engrossed. We can assume that the book had a special appeal that could entice people to read it... But considering Cameron Maysfield's extremely high mental strength, the probability of him being tempted is very low; perhaps he was simply attracted by the content of the book."

　"Just as he himself said, he wanted to use this to research the targeted transmutation of the demon race."

　"But his experimental research had only just begun; he hadn't even attempted to cultivate the 'Cerebrolysin' before the book suddenly disappeared."

　"Although he didn't say it, he must have tried to find it, and the final result was predictable."

　"In addition, the book disappeared on September 18th."

　"It has been exactly fifteen days since he found the book."

　“We can consider fifteen days to be a special number here.”

　"If that book possesses its own sentience and disappears on its own, it might have a fifteen-day observation period."

　"And Cameron Maysfield was not selected during the fifteen-day evaluation period."

　……

　Dak paused slightly and took a sip of tea.

　The three professors showed interest in his final statement about the "probationary period."

　Dark put down his teacup and continued, "Cameron Maysfield possesses extremely advanced mental magic, which sets him apart from others. If we don't attribute everything to some vague and ethereal fate, then the book likely chose him in the first place precisely because of this."

　"But I personally believe that the book ultimately chose to abandon it precisely because of this."

　"He was so well protected in his mental state that the book was impossible to use to control or influence his thinking. Therefore, he had to give up after the fifteen-day observation period."

　"If that book possessed normal thinking and logic, then it would have learned from its mistakes and, after experiencing a failure, would have chosen people with less strong willpower."

　"That is, backward compatibility."

　"This might not be a good thing for us, because it broadens our range of choices."

　"Furthermore, if it gains complete control over the mind of the second target, leveraging the characteristics of the 'Book-Eating Demon,' it can at least partially edit the target's memories."

　"The consequences of this are something that everyone can foresee."

　……

　There was a slight silence in the room.

　Professor Sylph began, "In other words, the screening system built on mind reading may not achieve the desired results."

　“Just as I thought.” Professor Cazell nodded slightly. “Mind reading isn’t a panacea; there are countless ways to circumvent it. Once it’s exposed, it becomes ineffective.”

　Professor Lily immediately exclaimed, "But didn't we find Cameron Maysfield through this?"

　“This is certainly a pleasant surprise,” Dark said. “And Spike Leon and Wit Gold, without this investigation, it would have been difficult to discover the hidden dangers within them.”

　"Don't forget, there's one last key person we haven't reviewed yet," Professor Kazel reminded us.

　Andrew Morton, a fifth-grader, is a rare "wizard"!

　……

　"The strength of one's mental will cannot be used to measure one's level. Since that book records the method of cultivating special demons, its purpose must be related to this. It must be a person with a high level of skill, but whose mental will is not outstanding."

　"From Cameron Maysfield's abandonment to Fern Morse's brain being implanted with 'Cerebrolysin.'"

　"That is, from September 15th to September 28th."

　"Only thirteen days have passed during this period."

　"To have completed in thirteen days the research that Cameron Maysfield failed to finish in fifteen, and to have successfully cultivated at least one 'Cerebrolysmic Demon,' the person it chose a second time must possess extremely high skill."

　“And Andrew Morton is an expert in this area.”

　After a brief discussion, the professors reached a consensus.

　Then Professor Sylph summoned Andrew Morton.

　……

　Andrew Morton was tall and muscular, looking like a bodyguard or thug at first glance, but he was a meticulous wizard.

　Since the memories of those being investigated were likely to be taken into consideration by some editors, Professor Cazell was even more careful in this investigation.

　But Andrew Morton performed flawlessly.

　The reason he hid his identity as a "wizard" was surprisingly ordinary—simply out of habit.

　His parents were both "wizards," but they were the kind of novice wizards who were only half-baked.

　Although they were fortunate enough to inherit the "wizard's legacy," their talent was quite ordinary; at best, they could only brew some strange ointments.

　They made money by selling plasters.

　However, due to the indelible stench and filthy appearance resulting from their long-term research, they were not popular, and only those plagued by poverty would force themselves to buy their plasters despite their disgust.

　Andrew Morton grew up in this environment.

　Therefore, he inherently felt that "wizard" was a lowly profession.

　Despite his large size, he harbors deep-seated inferiority complex.

　“Andrew Morton, can I take that as you looking down on your parents?”

　Professor Sylph's questions went straight to the soul.

　Andrew Morton was stunned, and then his face quickly turned red with shame.

　“No profession is inherently superior or inferior,” Professor Cazell said in a gentler tone. “Besides, ‘wizarding’ has never been a profession to be despised. Before ‘medicine’ was systematized, it was ‘wizards’ who saved the most lives. You’re already in fifth grade; haven’t you read *The Wizarding Chronicles*?”

　Andrew Morton left in shame, but his spine seemed straighter.

　"Was it him?" Dark asked after he left.
