Did the villainous professor survive today?

These words caused the previously quiet classroom to become chaotic once again.

"Really?"

"A second-tier character can use fourth-tier magic?!"

Has anyone done this before?

"..."

"Quiet!" Krenk warned the noisy students as if calling a bell from the dead.

"George, Julian, and Martha, you three, speaking in class without permission will result in a five-point deduction from each of you!"

Then, the classroom instantly became as quiet as a funeral.

"First, I will demonstrate spell binding for you."

As Krenk spoke, Enya brought in a demonstration puppet from outside and placed it to the side of the podium.

A bubble floated in Krenk's hand, its surface undulating like boiling water.

With a flick of his finger, bubbles splashed onto the doll's face.

The next moment, a ghostly blue flame burst into flames on the doll's face, scorching the damp surface and causing white steam to rise.

"As you can see, this is spell grafting, combining two completely different spells together."

Kroenke held up one finger as a reminder.

"Note that spell splicing and elemental affinity are two different concepts; don't confuse them."

offstage.

Meiwen's eyes widened instantly as she watched the doll in front of her burst into flames.

What's going on?!

Kroenk can combine spells?!

Did he prepare in advance? Or...?

Can spell splicing be achieved through external means?

Isn't spell binding a mandatory requirement? I've never heard of achieving it through external means before…

Besides, this isn't right.

In Mayonnaise’s eyes, Krenk was just a second-order academic fraud two weeks ago.

How did I get to the fourth tier in the blink of an eye?

Even a rocket couldn't reach this speed.

No, no! Don't overthink it. Since it's already happened, let's assume that Krenk is indeed at level four now, and use that as a basis to formulate a new plan.

Meiwen thought to herself.

Your actions have intimidated Meiwen, and in order to exact her revenge, she has decided to be even more patient and discreet.

[Points +4000!]

[Current points: 5250!]

Klenk picked up the chalk and drew a perfect circle on the blackboard. Then, he drew dense and intricate patterns in the center of the circle:

"As you can see, this is a very classic magic circle. Now, can anyone explain why a magic circle is drawn as a circle?"

Krenk's gaze swept across the entire classroom, then his finger pointed to an excited girl in the front row:

"Come here."

"Hello, teacher! My name is Adele! Because magic flows within a magic circle, and curves allow the magic to flow smoothly, aiding in circulation,"

"Very good. Next time I'll call on someone to answer. You don't need to introduce yourselves; I know all your names." Krenk waved his hand.

Why is a circle the most suitable shape?

Adele didn't hesitate:

"If it is a magic circle similar to a square, the magic power will overflow outwards when flowing along the edge of the magic circle because the corners are too sharp."

"Very good, that's a correct answer."

Kroenke nodded.

"Adele, I'll give you five extra points."

Krenk closed his textbook and placed it on his desk.

"Alright, everyone, close your books. What I am about to teach is something that no one in this book, or even in the entire magical world, has ever touched upon."

After he said that, a look of surprise flashed across everyone's eyes.

They put down their books at the same time, picked up their pens and notebooks, and listened attentively to the lecture.

Krenk raised his pointer and drew a square magic circle in front of everyone. At the same time, several ancient and mysterious occult runes were engraved inside the magic circle.

Immediately,

The magic circle emitted a soft blue light, and as magic power was injected and circulated, a dazzling white light emanated from its edges, moving along the boundary.

What is noteworthy is that when the white light reached the corners of the square magic circle, it only spilled out a very small amount of light, as if it was just naturally lost rather than due to inertia.

"Does anyone know why the magic didn't overflow at the edge of the magic circle?"

Krenk asked.

How did it suddenly veer from combining spells to drawing magic circles?

What exactly is he going to do?

Meiwen watched Krenk's lecture with a bored look. She rested her chin on her right hand and absentmindedly drew circles on the textbook with her left index finger, cursing Krenk.

Because she couldn't understand Kroenke's operation, Mayon's thoughts were not focused on the topic.

"Andrew, you answer this question."

Kroenke pointed to a blond-haired boy in the middle of the seats.

Andrew was surprised that Kroenke recognized him. He recalled a scene he had witnessed when his family took him to a magical exchange conference, and said:

"Because the arcane runes in the center of the magic circle are helping the magic to circulate."

"How did you make that judgment?" Krenk stared at the family crest on Andrew's chest, knowing that children from noble families were more knowledgeable; they might know the answer, but not why.

"Forehead……"

A bead of sweat trickled down Andrew's temple, and he apologized awkwardly.

"I'm sorry, teacher, I'm not quite sure..."

"It's alright, sit down, Andrew," Krenk said, his gaze shifting to the other students.

"Are there any other students who know the answer?"

With Andrew's endorsement, hands shot up like mushrooms after rain.

Krenk's gaze fell upon a thin boy in the corner of the classroom, who was struggling to raise his hand.

Ellen Delap

Death threat: None

What a tiny boy! He must still be developing. How come he's so young and already at St. Auster Magic Academy?

As is customary, the academy only admits adults because teenagers are still developing and their magical circuits are not yet fully formed. Therefore, if they suffer any serious injury or accident, it can easily cause irreversible damage.

Kroenke's heart stirred slightly, and he decided to give him a chance, while also getting to know this student better:

"Allen, is it? You answer that."

Allen pushed up his thick-rimmed glasses:

"When they reach each node, the arcane runes emit a bright light. Therefore, it can be inferred that these arcane runes reduce the loss of magic power due to inertia when the magic reaches the corner."

"Yes, that's a correct answer."

Kroenke nodded.

"Alan, I'll give you 5 extra points."

After speaking, Kroenke turned his gaze to Andrew, who had answered earlier:

"Andrew, although you gave the correct answer, you did not show your process, so you can only get 2 points."

Andrew glanced disdainfully at Allen behind him, who was only staring excitedly at Kroenke and did not notice Andrew's gaze.

This lack of response is actually the best provocation to the other party.

"Alright," Krenk tapped the table.

"Now, I'm giving all of you half a class period to think independently about how to achieve the effect of spell splicing in this way. In twenty minutes, I will look at all of your problem-solving approaches."

Kroenke took out his pocket watch and pressed the timer button.

"Now, let's start the timer. In twenty minutes, I want to see the results of all your thinking."
