116 - Cartesian Coordinate

After listening to the accounts of several people, Pierce and his companions found it hard to believe, even suspecting that Elok was deceiving them.

The classroom of Arcane Mathematics was a whole 600 meters away from the training ground, with a towering screaming tower several tens of meters high in between. Could they really hit that from here?

But the twelve training dummies with smashed heads and the testimonies of Dakka and the others told them that it was all true.

The group of apprentices, puzzled, all turned to Lynn, waiting for his answer.

"It's simple. Just calculate all the data and work it out, right?" Lynn said with a smile.

During his time as a professor, he had already recorded every location in the Iyeta Academy with the help of AI. So, he had a clear understanding of the position information for each training dummy. All he needed to do was construct the corresponding parabolic trajectory equations and make minor adjustments for interference factors such as wind speed.

"The same attack can be replaced with fireball spells or even more powerful magic." Lynn added.

Elok and the others couldn't help but shiver, as no one wanted to be walking down the street one day and have a massive fireball drop from the sky and hit them on the head. It was just too terrifying, not even knowing how they would die.

"Professor Lynn, is this the magical technique you've researched during this week?" Mr. Tike, who had been listening, asked with astonishment.

"You could say that." Lynn shrugged, conveniently using it as an explanation for his unexplained one-week vacation.

"Professor, when can we learn this kind of magic?" Debra raised her hand high, full of curiosity.

"Since you all want to learn this, at the end of this month, I will organize an examination for Arcane Mathematics. If someone can solve all the questions, I will teach them this improved magic, and even allow them to apply for graduation ahead of time," Lynn promised to the group of apprentices.

However, his words weren't meant to deceive. He didn't expect these wizard apprentices to master very advanced mathematical knowledge. As long as they could complete most of the knowledge from elementary and middle school, they could apply for graduation. After all, they could continue their education after becoming official wizards.

In fact, this exam was also to help Jenny advance. Now that she had become an official wizard, it was better to secure her status as soon as possible.

Fueled by the prospect of learning improved magic and applying for early graduation, the group of wizard apprentices burst forth with unimaginable enthusiasm. They were more focused during class than ever.

Pierce was especially excited; Lynn's promise was undoubtedly his only chance to become an official wizard as a mediocre talent.

"Next, we will continue with the explanation of the Cartesian coordinate system, just some basic knowledge," Lynn extended his hand and used magic to draw a cross in the air, launching into the lesson.

After the Arcane Math class, Elok and the others left the classroom, either lost in deep thought or looking bewildered. Their minds were filled with terms like absolute value, the first quadrant, the second quadrant, the X-axis, the Y-axis, from this point to that point...

Pierce glanced at his notes, feeling like he had understood it but also not entirely. He decided to contemplate it further when he got back.

"Mr. Tike, please stay for a moment," Lynn called out after packing up his teaching materials, stopping Mr. Tike from leaving.

"Professor Lynn, is there something you need?" Mr. Tike paused, then continued, "The concept of the coordinate system you introduced in class is very interesting. It seems like it can precisely locate any object in space. I wonder if this was the idea of some great master or perhaps a legendary wizard..."

Compared to the apprentices who were engrossed in learning superficial knowledge, Mr. Tike understood just how important this was. He guessed that Lynn could hit those dummies with pinpoint accuracy from hundreds of meters away, even avoiding the entire Screaming Tower. It seemed to involve knowledge in this area.

"That's an idea put forward by a master named Descartes," Lynn replied with a smile, answering Mr. Tike's question.

After listening to their stories, Mr. Tike and Lynn couldn't help but be amazed by the profound nature of this subject.

"Descartes... it would be an honor to meet these masters of arcane mathematics," Mr. Tike sighed, increasingly astounded by the depth of this field.

"There might be a chance in the future." Lynn replied with a smile. He then adjusted his expression and expressed his gratitude. "I heard from Rol that you've been helping me with the patent application for the Airship. I haven't had a chance to thank you."

"It's just a small favor. I can't sit through so many Arcane Math classes for nothing." Mr. Tike laughed heartily.

After some small talk, Lynn seized the opportunity to ask about alchemy. "I heard from a scholar within the Society of Mystical Arts that some wizards can enhance their abilities and break through their limits using alchemical arrays. Is that true?"

Hearing this, Mr. Tike's brow furrowed slightly, but he still explained, "Alchemy can indeed achieve similar effects, but nowadays, very few wizards in this land actually practice it."

Mr. Tike's explanation was brief and to the point, without going into detail. A century ago, when the management of the land of wizards was lax, the methods for promotion in various schools were diverse, leading to many undesirable outcomes. This was also related to a scandal that the Wizard Council preferred not to mention, and it involved the Dark Wizard Murk. Mr. Tike didn't want to delve into such knowledge.

Lynn understood this and changed the subject, asking about the layout of alchemical arrays and their decryption.

This time, Mr. Tike was more open and patiently explained everything to Lynn.

The two of them talked all the way to the professor's lounge. When they saw the silver-haired witch standing at the door, Mr. Tike couldn't help but smile.

"I'll go back by myself, Professor Lynn," Mr. Tike raised an eyebrow and quipped.

Lynn could tell that Mr. Tike had misunderstood, but before he could explain, Mr. Tike had already tactfully turned and left.

Lynn shook his head, opened the door, and invited the witch in before asking, "Jenny, after your promotion yesterday, did your body experience any discomfort?"

The silver-haired witch shook her head, looking puzzled. "Why do you ask? Is there something wrong?"

"No, there's nothing wrong. I was just curious," Lynn shook his head. It seemed that the potency of the potion Jenny had taken wasn't sufficient to reveal the Eye of Death in her consciousness.

"Next, let's get to work quickly. We only have two hours." Lynn said, looking at the witch, urging her to focus.

The theory of the cartesian system was proposed by a French philosopher and mathematician called Rene Descartes in the 17th century.
