"I'm sorry."

Rogers couldn't help but say this, he didn't know why he apologized, but he always felt that there seemed to be a lot to apologize for.

As Alina said, because of the constraints of the [Liqi Bonus], it is impossible for her to do things harmful to herself, not to mention, she already knows a lot.

Thinking back to the night she brought wine to talk, Rogers couldn't help but reflect on the unease he felt when he recalled the memories of his past life, and there was no need to make up for it from controlling Alina.

Fang treated her with the attitude he had when he first met, and it was indeed natural that he would make her angry.

"A philosopher once said that you should be cautious about things that can be controlled, and be optimistic about things that are not controllable, and you can only do what you can do, and you have to accept this fact and deal with it with optimism.

"I think I should think about what it means and get rid of the bad habit of getting caught up in detail and perfection."

Rogers looked into Alina's eyes, spoke in a calm tone of Epictetus' quote, and then asked in a rather relaxed tone:

"So, our relationship is going to be pretty good in the future, right?"

Alina listened to Rogers's apology, watching Rogers's book-like face change speed, her momentum was a little stagnant for a while, and she replied inexplicably: "Probably." ”

"I'll restrain myself as if you hadn't come back since that night to dig up what I didn't want to say."

As Rogers' promising words spoke, Alina's hand on the collar gradually loosened, and she groaned slightly, also apologetically:

"As you say, I shouldn't be childish, either in the matter of dealing with the saint or in this matter......"

"So, our physiognomy is really bad." Rogers sighed helplessly, then turned to look at Rufia and smiled reassuringly, "We're fine, it's the same as before." ”

He said so, but he knew that something had changed, like he could really try, with a little bit of trust.

He wanted to tell Alina that he had never trusted Alice, that he had only trusted himself all along.

But when the words come to the mouth, they can't be said effectively, as if they are blocked in the throat.

"Then let's go find the workbench first, it just so happens that we are in a group of three!" Rufia breathed a sigh of relief, smiled and grabbed Rogus and Alina's arms, gesturing to find the right place.

She could clearly feel that the atmosphere just now was very abnormal, and this time the dispute was completely different from usual, otherwise she would have stepped forward to persuade the two of them to disperse, instead of watching worriedly......

Because the number of students is much larger than the alchemy workbench equipped in the classroom, each alchemy table must be assigned at least three to four students.

It was also in the process of looking for the alchemy platform that Rutgers also somewhat understood why so many of his classmates were avoiding him before.

At a glance, he saw the twisted and pretentious Caspar, who was constantly telling the third prince something, and the third prince's expression was quite polite, but the corners of his mouth that couldn't stop twitching were already clearly indicating the mood of the royal noble.

Because of Caspar's changes, I don't know what kind of notoriety they will make up for themselves next......

Rogers pondered in his mind as he smoothed his crumpled collar with his hand.

"Not bad! The students of St. Herte should pay attention to their own decency in this way! Rutgers plus 100 credits! ”

The loud announcement that rang like a bell instantly spread throughout the huge classroom, and every word of the voice was incomparably clear and powerful, as if it could penetrate people's eardrums.

Rogus looked down and saw Professor Curley, a stout, short, bearded man standing beside him, and he didn't know when he appeared.

He was one of the deans who had invited him to the temporary dormitory, and he was also the first professor to take the initiative to praise him and express his willingness to teach him in private.

Xu was the reason for the lecture, Kuli was wearing a simple gray magic robe today, and a pair of glasses with thick lenses resting on his rosacea.

This outfit, which should have belonged to an old pedant, couldn't help but reveal a strong disobedience and weirdness when it was forcibly put on his body.

"Professor, isn't it good to award credits because of these little things?"

One of the students on the side couldn't help but speak up, which immediately attracted a burst of echo.

Today, Professor Curley can add 100 credits for Rutgers' decency, and tomorrow he will be able to add 200 points for Rogers' left foot in the classroom?

This eccentricity is too conspicuous! It's outrageous!

"Don't you think it's bad too?" Currie looked up at Rutgers, as if sensing that such a blatant bonus might be a little out of place.

"As a student, my task is to follow the teachings of the instructor, and if you think it's not good, it's not good."

Instead of answering the question directly, Rogers made a sincere statement that he would respect Curly's majesty as a mentor.

"Hahahaha! Good boy! I love your words! Rutgers adds another 100 credits! ”

Curry let out a hearty laugh, the high-pitched tone and deep bass that seemed to cause the air around him to tremble.

The students fell silent when they heard this, and no one came out to denounce this obvious injustice, for they feared that for every additional word Rogers might have to add another hundred credits.

"Okay, I see that the number of people is also there, you open the prologue of the textbook, and I will tell you what you will learn from me in the future.

"Oh yes, my name is Kuli! It's a simple and powerful name, and I hope you all remember it well! ”

Curly's opening remarks were extremely casual, a stark contrast to Yalana's style yesterday.

Thanks to his loud voice, no matter how far away the students are, they can hear him word for word.

"The basic structure of the magic circle cannot be simply summarized as concentric circles, which is a misconception that many apprentices will have when they first get started!

"But you must also know! The magic array with the circular body as the layered structure must be the most stable!

"And whether it is a single or a composite circular structure, their parts about energy supply, conduction, function and insurance are similar!

“……”

Rogers spread out the textbook on the alchemy table, but he didn't understand how what Kuli was talking about and the prologue, but it sounded very simple and a little contradictory empirical knowledge, and I am afraid that it was the precious essence of the great magician.

After listening carefully to a lot of knowledge about the formation structure, he thought about the topological structure called the "Möbius Ring" proposed by Mobius and John Listin in the 19th century, and wondered if it could be added to the composition of the magic circle.

After Ku Li finished speaking, Rogers tore a piece of manuscript paper on the alchemy table into a long strip, and then quickly folded a Möbius ring: "Professor, if this is the structure, can it form a formation base or other parts?" ”

If the Mobius Ring can, then the Klein Bottle may also try it in this fantasy world.

In addition to these two archetypes, there is a whole host of topological structures that are constantly popping up in Rogers' mind.

Standing next to Rogers, Curry looked up at the Möbius Ring, he was a little puzzled at first glance, but after a moment of realization that this was a structure with only one face and one boundary, he was instantly immersed in deep thought.
