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

　Sure enough, Anita arrived at the door with two other classmates.

　So he pointed to the form, stuck it on the door, and said with a smile, "It's all here. You can take a look if you need it."

　The two students exclaimed with delight, "Thank goodness we have Dark!"

　"I'm going to sleep now." Dark locked the door again and quickly began practicing [Netherworld God Technique].

　During the half hour of practice, people passed by outside the door from time to time, but none of them disturbed him.

　That night passed quietly like that.

　The next day.

　Thursday.

　The first class in the morning is arithmetic.

　Dark could roughly guess that Professor Lily would most likely teach about "equations" in this class.

　The basic equations themselves are not difficult, and they are very useful for simplifying some calculations.

　But for beginners, no new knowledge is easy to grasp. I hope Lily can teach me.

　Please try to teach in a simple and easy-to-understand way.

　However, he never expected that he had underestimated Professor Lily's limits!

　"Jingle Bell!"

　The little fairy with fluttering dragonfly wings entered the classroom as the bell rang.

　The students in that grade immediately raised their heads like hungry lambs, eager to learn.

　Looking at the arithmetic professor with eyes full of eager anticipation (seriously).

　"Today we're going to learn something new."

　Professor Lily waved her magic pen with a smug smile.

　As the students went into a state of high alert, she suddenly pointed at Dark.

　"Next, please welcome our substitute professor, Dark Demon, to the stage to give his lecture!"

　"Clap clap clap!"

　The students were quite surprised, but it wasn't the first time Dak had substituted for a class, so most of them...

　Everyone cheered and started studying, following the atmosphere.

　But while applauding, almost everyone couldn't help but look at the person sitting in the back corner of the classroom.

　A blond boy.

　What caused a professor to shamelessly request leave without actually asking for it?

　Students substitute for teachers

　Is it moral decay or the distortion of human nature?

　What's wrong with this world?

　Dark endured the intense gazes directed at him, his expression slightly stiffening.

　He had no choice but to put down the book he was reading, "Complete Explanation of the Elements of the Venue Card".

　He originally planned to use this class time to learn about the zoo, but now it seems that was too idealistic.

　"Professor Lily."

　Dark stood up with a frown.

　This time, however, he did not follow Professor Lily's wishes.

　Instead, he spoke directly;

　"I don't think being lazy is good."

　Professor Lily immediately covered her mouth, her adorable eyes widening in astonishment. "What do you mean by slacking off? I'm the most diligent little fairy in St. Marian!"

　→After all, Saint Marian is now just a little fairy!

　Dak understood instantly, and three invisible black lines immediately appeared at the corners of his eyes.

　Then she thought of that night she spent with Professor Lily, and her heart softened.

　However, Professor Lily's act of asking someone to substitute for her in front of the students when she had nothing important to do was really going too far.

　Furthermore, she didn't give him any advance notice or give him any time to prepare his lesson.

　What you do today will have tomorrow's consequences.

　If we let her continue to push her luck like this, what will become of us?

　In that case, we might as well rename this arithmetic class "Dark Dumont's Arithmetic Lecture".

　Therefore, such behavior must not be tolerated.

　Darke immediately said, "Professor, I'm just a student. Helping out occasionally is fine."

　Professor Lily immediately interrupted, "I'm absolutely certain that your talent in arithmetic is sufficient for a professorship. Perhaps I should give Arte a letter of recommendation so you can become a full-fledged teaching assistant—what a brilliant idea!"

　Dark: "Professor Lily!"

　Professor Lily: "Here!"

　Dark: "Please try a little harder!"

　Professor Lily: "But I don't know how!"

　Dark: "Please try a little harder!"

　Professor Lily: Ziru Ba.

　Professor Lily seemed to finally understand Dark's good intentions, and stopped arguing. She simply flapped her wings and flew back to the podium.

　Dak nodded in satisfaction and sat down again.

　However, they failed to notice that the entire classroom of students witnessed his entire conversation with Professor Lily.

　After that, everyone was dumbfounded.

　"Who is the professor and who is the student?"

　Professor Lily is clearly the older one, so why does Dark Deamon look more like the older one?

　Teacher

　"No, wait."

　Emma in the front row suddenly spotted something interesting!

　"Didn't the professor just say that Darko Dimon's talent in arithmetic is sufficient for him to be a professor?"

　Job

　Susan and Lucy, sitting on either side of her, nodded like chicks pecking at rice; they had heard it too.

　Arithmetic class is obviously so difficult, and they are struggling to even grasp the content taught in class.

　However, some of his classmates received such high praise.

　This sense of disparity is truly unpleasant.

　Witt couldn't help but ask Robert, "Is the difference really that big?"

　Robert opened his mouth, then after a moment said, "Let's see what Professor Lily is going to teach in this lesson. Perhaps it won't be that difficult."

　Witt swallowed hard and subconsciously twirled his pen: "Let me take a look first."

　Amidst the students' soft whispers, Professor Lily drew a large "X" on the blackboard!

　"Today we're going to teach about the unknown X. Using..."

　As she spoke faster and faster, the classroom fell into a deathly silence.

　What is an "unknown"?

　What is an "equation"?

　Professor Lily gave a complete definition of these two concepts in her own words.

　In her view, both concepts are very simple.

　Once you understand the definition, you can apply it directly.

　But in order to help the students understand better, she followed Duck's example and used the analogy of a chicken and a rabbit.

　Word problems involving the same object in a cage.

　That is, we jumped directly from a univariate linear equation to a system of two univariate linear equations (I).

　As intelligent as Emma is, she would not be stumped by a question of this magnitude.

　But for a fool like Diana, it was like listening to gibberish; all that was left in her head was a buzzing sound.

　She blinked and stared at the blackboard, mechanically copying down her notes.

　Rose, who was beside her, was in no better shape.

　When people encounter entirely new knowledge, they always need a transition period. A cramming-style, rote learning approach is ineffective.

　Education will only have a negative effect.

　Although Rose felt a headache coming on, she, like Diana, diligently took notes.

　In short, just copy it down first!

　This is the learning secret that Dak taught them.

　"Clap, clap."

　Every now and then, the sound of a pen falling onto the table after a failed spin could be heard in the classroom.

　Professor Lily's voice was like a lullaby, soothing the nerves of the young mages.

　Until she wrote a new word problem on the blackboard and prepared to call on someone to solve it, the hypnosis...

　The music suddenly turned into a terrifying dirge, waking everyone up!

Chapter 264 Darkdemon's After-School Tutoring (4k)

　[Suppose there are several mages and a one-headed, four-legged magical sprite in the same arena. Counting from above, there are 35 heads and 94 legs. How many mages and magical sprites are there in the arena?]

　A simple chicken-and-rabbit problem.

　But for a first-grader who has only been learning equations for an hour, it's not so simple.

　Professor Lily observed the classroom for a while and felt that randomly finding someone to solve the problem at this point would be very...

　There was a possibility of some awkward situations that she didn't want to see. So instead of calling out names randomly, she chose Emma Metis from the front row.

　As Emma stood up and went up on stage, the students in the classroom all quietly breathed a sigh of relief—it wasn't their turn.

　Just do it!

　Emma carefully recalled Professor Lily's previous examples, and although she didn't quite understand them, this problem...

　The format is almost identical to the example problem, so it's not difficult to solve by imitating the example.

　She wrote down the answer quickly.

　"Correct! Emma Metis gets five points!"

　Professor Lily was clearly excited, feeling that she still had a talent for teaching.

　Someone learned it after only one explanation.

　For the rest, you can just reinforce your understanding with practice exercises!

　Luckily, she worked overtime last night to finish a test paper, and now it's in use.

　perfect!

　After that, she didn't ask anyone else to come up and answer the question, but instead explained the problem that Emma had solved.

　After reviewing the papers, they began distributing the test papers.
