Xia Lin's test paper would have been done by even a junior high school student in his previous life, but in this world, it should still be difficult, after all, the students of the academy have never been exposed to even the simplest mathematical equations other than addition, subtraction, multiplication and division.

The four major questions in Xia Lin's test paper are all related to plane geometry and space geometry.

In order not to let the younger students be at a loss and unable to even touch the door, in front of the question type, Xia Lin will use a large paragraph to explain in detail the formulas and theorems that need to be used to solve the question type, as well as the basic mathematical symbols, proof writing format, auxiliary lines, coordinates, and coordinate system knowledge.

Compared to a test paper, it looks more like the sample question answer from a reference book in a previous life.

Of course, the problem types of space geometry are quite simple, which is nothing more than proving that two line segments in a space graph are parallel, and finding the length of a line segment.

In fact, this exam tests the students' comprehension and learning ability of geometry.

Luna Salin, a second-year sergeant at the Royal Academy of Magic, whose father was a sailor on the Bluegrass, spent the first half of her life running around the Flanche Sea before meeting Luna's mother in the Kingdom of Clancydia.

However, because the smuggled goods on her body were discovered by the kingdom's customs officials, Luna's father was hanged on the docks by the kingdom guards, and her mother had no way out of life and had to escape to the Bluegrass to do some pulp and sewing work.

Growing up on a ship, Luna has an excellent spatial imagination and is able to easily find her place on the complex Bluegrass.

Later, at the age of twelve, Luna was discovered to have an excellent talent for mental power, so she enrolled as a cadet sergeant, and her talent in this area also helped her a lot when it came to learning runes.

While everyone else was trying to make mistakes over and over again, she had managed to construct runes according to her own feelings, and in her opinion, weren't these runes just the compartments of the Blue Grass? Why do you find it difficult?

Today, however, Luna's faith has taken a terrible hit.

What two points determine a straight line, what right triangle short side length square will be equal to the third side length squared such a thing, even can't read it, who can make those strange problems?

Luna scratched her head a little frantically, and the tip of the dipping pen in her right hand hung in the air, slowly dripping a drop of ink that almost stained the paper.

Looking left and right, seeing that the other students were meditating on the test papers, Luna was unwilling to give up a high-paying part-time job with a daily salary of 4 silver mar.

She took a deep breath and exhaled slowly, opening her eyes to the simple theorems and formulas, and her brain began to rac.

Straight lines, line segments, triangles, side lengths, right angles, etc., are easy to understand, and the square seems to be multiplying the same number, so that's it......

Calm down, Luna showed a strong understanding of the mages, and gradually grasped the knowledge contained in these concise theorems and formulas through self-study without any guidance.

She began to imagine triangles and quadrilaterals, the length of their sides, and their inner angles.

Depending on the meaning of the bizarre letter symbols, this problem can eventually convert the length of this edge into the ratio of the length of the other side corresponding to the corner to that edge......

After a long time, Luna finally solved her first plane geometry problem, and she breathed a sigh of relief as if she had accomplished something terrible.

Luna couldn't tell how long it had taken her to look through the tall crystal windows of the Rose Palace, but after thinking about it, she decided to keep doing it, because she found that the formulas, theorems, and lines seemed much more interesting than the Bluegrass she had grown up on.

……

"It's time!"

Xia Lin had been talking to Dean Manan about the magical changes proposed by Princess Dorothea and himself, but he was also silently counting in his mind that in the era when there was no precise timer, he could only get an approximate time in this way.

He counted silently until 4,000 times, and then Xia Lin spoke up and asked the students in the auditorium to stop answering the question:

"Okay, please pass the test papers from left to right in turn, and the students sitting on the far right of the long table should bring up the collected test papers! You can sit in your seat and discuss it for a while, and I will correct the test paper right away! ”

"It's really interesting, it looks like the test method that the university students teach their students to use, and it should be very effective, but the paper consumption is a little too much!"

Dean Manan on the side took out a pot of snuff, sniffed it, and commented on Xia Lin's test method with interest.

"Don't worry! Dean Manan, after the establishment of the paper mill, paper will no longer be a problem for the dissemination of knowledge.

It will become more and more common to judge students' mastery of knowledge through test papers and exams.

At the same time, there will be a variety of media in the future, and even ordinary civilians will be able to write their own stories for publication or even print them into books for sale! ”

While putting away the test papers, taking out red ink and dipping pens to prepare for on-site correction, Xia Lin depicted the cultural development that cheap paper can create in the future.

"Although it sounds bizarre, but with two copper bis on a piece of paper, maybe the world you are talking about is really possible!"

Dean Manan sniffed snuff and nodded in agreement.

Through the conversation just now, he already knew why Xia Lin, a one-ring mage, was able to obtain the support of Her Royal Highness, although he was not satisfied with the use of the precious Golem core in the so-called factory, but Dean Manan also got a lot of inspiration from it.

Indeed, who said that magic can only be used to fight and kill? Aren't the various convenient rune plates used in the mansions of nobles since ancient times a corner of the world depicted by Xia Lin?

If magic could be spread throughout the empire, how prosperous would the mage community be?

Maybe there will be an amazing and glamorous person like Xia Lin among them, who will solve the mystery of the high-ring spells that have plagued the great magicians of the Six Rings for generations.

Dean Manan sniffed his snuff and thought silently, but Xia Lin did not have so much emotion as him, but was engrossed in quickly correcting the test papers.

Despite the hints they gave and their comprehension was extremely strong, there were not many people who were able to do these five questions that the mages had never been exposed to.

There are also many test papers with only one name written on them, and the rest of the paper is blank.

Xia Lin sifted through it and got a total of twenty-three test papers, of which seventeen did one or two questions in plane geometry, and the correct rate was 100 percent, it seems that these mage apprentices have understood the knowledge of plane geometry.

There were only six papers left that did the space geometry questions that followed, three of which had errors, and only one of them, the one with Luna Salin's name written on it, got three questions right, and finally the big question actually went to paper.

Xia Lin looked at her answer ideas and found that if it weren't for the lack of time, she looked like she could finish it, and couldn't help but be a little surprised by the mage's comprehension.

After all, although these questions are simple, the mathematical symbols and proof formats that appear in them are unprecedented, and being able to understand and eat the information provided by Xia Lin in such a short period of time, this child not only has the strong memory and comprehension ability of a mage, but also has the best talent in mathematics and geometry.

"Okay, I'm going to announce the list of people who meet the requirements, and if they want to, these people can sign a temporary researcher contract with Carr Lab now, and come to the lab every afternoon from six to ten o'clock to participate in the project's research."

"These are Ocassi Noll ......"
