What is it like to be a teacher as a magister?

Chapter 11 The Little Ice Selling Girl

"But speaking of it, ice cubes are not cheap, right? Is there anyone here in West City who can afford them? If they can't be sold immediately, it may be difficult to put them on the next day."

Ke Lin couldn't imagine how to sell ice water in a place without refrigeration and insulation.Get a wooden box and cover it with a cotton jacket?
"It's not expensive, so it sells well."

There was a bit of mystery in Annie's smile, and she explained:

"In the Magician's Association in the central area, I am very familiar with the old man at the back door. I exchanged fifty catties of charcoal for a year for a job that helps clean up the garbage every day.

"The salary is not much, but there is one advantage, that is, you can enter the place where magicians are trained. Do you know how many ice cubes are produced by magicians who practice frost magic every day? They leave after practicing, so many ice cubes Just leave it there to melt, what a waste.

"So every time I go to clean up the garbage, I will secretly bring back some ice cubes and sell them here. Don't underestimate these. They are not expensive, and they are compared with those exquisite drink shops in rich areas. Anyway, I have almost no cost. Excluding those who bribed the old man, I can earn dozens of silver shields every year.

"I have already thought about it. I will buy an inconspicuous trolley this summer, so that the efficiency of transporting ice cubes will be greatly improved. At that time, I will let the people on the whole street be able to travel in the scorching heat." Drink ice water in summer."

At the end of Annie's speech, there was a faint aura of wanting to akimbo.

Colin was stunned when he heard this. He thought that Annie was a very interesting girl. Sometimes she had a single-minded mind, and sometimes she was very clever.

"Aren't you afraid of being discovered by the Association of Magicians?"

"I don't steal anything valuable, and those ice cubes were originally unwanted."

When she said this, she suddenly felt a little embarrassed and said: "I'm so sorry, I kept talking about my business, and I almost forgot the business."

"It's okay, I'm quite interested in these things, not to mention it's still early today." Ke Lin looked around and said, "But if you're here, will it delay your business?"

"No, not many people buy charcoal in the morning."

"why?"

"Because poor people generally only use charcoal for heating at night, and if they don't feel too cold during the day, they won't come to buy it, so sometimes when the weather changes, many people will freeze to death." Annie said sadly but accustomed to it.

Regarding the issue of poverty, Colin of the two worlds has the right to speak, but it is obviously not the time to talk about it, so he changed the subject in time:

"Then shall we begin?"

"Hmm." Annie cheered up immediately.

Since the last appointment on the hills outside the city, the two of them had exchanged questions about magic pattern calculations after they returned, but although Annie was considered smart, she still couldn't keep up with Colin's thinking, so Annie was basically When asking questions, Colin will explain.

In exchange, in addition to inspiring his own thinking during the discussion, Colin could also get a lot of knowledge and anecdotes about magicians and the magic circle from Anne.

These are all what Annie helped a magician at the beginning, and the other party mentioned it when they got along with her. It is precisely because of this that she has the opportunity to be recommended to enter the Hall School of Magic. , I'm afraid I won't be able to save enough sponsorship fees in this life.

The two sat on the ground in front of a tattered low table in the shed, using stones to carve on the ground and table instead of pen and paper.

After half an hour.

"The parallel problem of these two surface domains has finally been solved. Thank you very much, Ke Lin. If you let me think on my own, I'm afraid I won't be able to figure it out before I graduate."

Annie let out a long breath, and then moved the stiff muscles caused by maintaining one movement for a long time.

Colin said a few words politely, and then asked with some doubts: "Speaking of which, why didn't you think about the possibility of them being parallel before? You have also seen that the final proof process, although a bit cumbersome, is not a matter of fact." How difficult."

"It's already hard at this level."

Anne couldn't agree with Ke Lin's point of view. Her theoretical grades in the college can be kept in the top three all year round, but even so, it took several days to barely understand the proof process under the one-on-one guidance .

Saying it's not difficult, doesn't it make you look stupid?

Colin was at a loss for words for a while. His biggest problem now is that he lacks a systematic understanding of magic theory. After all, what the academy taught during his apprenticeship was only the most basic things, not to mention the most cutting-edge and cutting-edge research. He can't get in touch with popular topics in the teacher's circle.

It's true that the talent is strong.

But it is difficult for a clever woman to cook without rice, and there is a limit to drawing inferences from one instance.

No matter how smart a person is, it is impossible to prove Fermat's last theorem with only four arithmetic operations.

Colin didn't know how to answer Anne, so he could only ask back: "If you think this is difficult, then the next question about regression counting tends to the α surface domain should be even more difficult, do you want to continue?"

"Go on!" Annie gritted her teeth.

Another half hour passed.

Annie looked down at part of the proof written by Colin, her brows were frowned, and she kept biting the nail of her index finger with her teeth.

"To be honest, Colin, I really can't agree with this paragraph. Do we have different understandings of Ubern's constant?"

"Don't think about this constant, first substitute the trajectory of the semi-ellipse module into the set and compare it again, you should be able to find that the induction method we have been using all the time is actually taking a long way..."

"Still don't understand."

"..."

"Can the mapping relationship here be calculated without exhaustive methods?"

"..."

"I see, it really is my understanding of Ubern's constant is too superficial."

"..."

Annie was right. There was indeed no business in the morning. For more than an hour, only one woman came to ask the price of charcoal, but she didn't buy it in the end, which made Annie, who was already a little irritable, even angrier.

"Thank you, Colin. Although I didn't fully understand it, I still gained something. At least it allowed me to further confirm the correctness of your conclusion."

The back and forth, endless questions and explanations made both parties feel very tired. Annie was really embarrassed to continue asking, because she still had a lot to digest today.

"Are you still doubting the conclusion?"

"It's hard not to doubt."

Annie rubbed the center of her eyebrows: "Among the positive values ​​of the non-stretching mapping arc, there are infinite pairs of regression counts that tend to the α surface. Don't you think this conclusion is too absolute?"

"Is there?" Colin disagreed, "Don't you think this is very mathematically beautiful?"

"How beautiful is this? It's obviously very awkward! And it gives me the feeling that once your conclusions are established, many space-based magic theories will become... even more awkward."

"Is this a bit exaggerated?" Colin was taken aback.
