Although it's really a bad taste for Lena to let the magic girl shout "expansion", it's true that this spell is used to exercise Dana's casting control.

According to the test, Dana's own magic reserves are more than 50% higher than those of her peers, which means that when she casts magic, she needs to spend more energy than ordinary people in controlling her own magic flow. If she can't handle it well and the structure of the magic model is unstable, it will easily lead to the failure of casting.

The usual failure of casting is nothing but a failure to interfere with reality, but the failure of Dana's casting will lead to explosion.

The reason is that the original magic lost its control in the process of transformation, which turned into a turbulent torrent of energy.

From Dana's body, Lena realized that a little bit of magic is unusual, because even a simple zero ring magic light can cause such a serious explosion in the case of failure, which means that the magic used in this magic actually contains extremely high energy, but the light does not reflect it, just like lighting a candle not worth mentioning.

Lainer speculated that magic itself contains high energy, but the conversion efficiency is very low.

This is not his first discovery. You of the High Council have discovered this problem for a long time. In fact, you Herman Bragg discovered that casting magic in the form of magic model can improve the utilization rate of magic, and then created modern magic.

However, no one can make perfect use of magic. Even the most concise magic model has less than one thousandth of the utilization rate of magic. In the words of Reiner, they really waste this energy.

But Lena's current level is still too low, and he has no access to relevant knowledge, so he can only press the no table and wait for the solution of this mystery in the future.

Put the goal in front of you, and the reconstruction of the startower is coming to an end. Soon, the astrology course will be reopened, but the teacher has become a problem.

Today's four teachers, apart from Claire, who is the mascot, are Susan Michelle, who teaches alchemy and necromancery. She is also a school doctor, Helena Hawkins, who teaches elements and laws, and Sally bateric, who teaches change and magic.

Obviously, not to mention the mechanical department, astrology teachers are short.

In fact, even for other subjects, part-time teachers are insufficient, unable to give consideration to the teaching of the two subjects. For the course whose teachers are not full-time researchers, most of them are simply popular science teaching, which is difficult to meet the needs of magic assessment.

"I can't think of worrying about the enrollment rate everywhere."

Lena shrugged helplessly. He took a look at the design in front of him. It was drawn in his spare time. He had been busy for a long time, and then he was finally able to put it on the agenda.

Those are two suits.

One of the top is the common suit of men's aristocratic dress, which is in navy blue color. Inside is a beige sweater vest and white shirt. The lower body is a combination of plain skirt and black shoes. The skirt is just above the knee. In order to keep warm, there is also a pair of black silk stockings. This kind of men's dress originated from the ancient magic period has long been out of fashion, but it is used in many fields For the first time in women's wear.

The second one is much lighter. The jacket is light and short sleeve. The collar of the jacket is very special. It looks like the Navy's navy uniform. The skirt is the same color as the scarf. It just touches the knee. The white socks only reach to the calf. With small shoes, it looks very youthful.

Two sets of clothes are painted on the chest of the location of the crescent college logo, a crescent, it is obvious that this is the school uniform designed by Lena.

There is no concept of school uniform in this world, because the vast majority of students in magic schools are wearing heavy mage robes, even in women's schools like crescent college.

But Lena also saw that for students, it's OK to wear in winter, but it's obviously not suitable in hot summer.

Therefore, he wants to design this kind of school uniform for the sake of students' better learning, not for his own selfish desire.

Yes, that's it!

Lena is very good at painting. Combined with his own memory, he restored the common suit skirt and sailor suit on the earth.

Sure enough, girls still have to wear short skirts!

Put away his thoughts, Lena quickly took the design to find Dana who was studying in the classroom.

Dana frowned after explaining what she had come for.

"Wait a minute. I've only taught myself a little bit about tailoring. At most, I'll just mend my clothes like this."

She raised the sleeve, there are obvious stitching marks on it, but the stitches are very good. If you don't compare them carefully, you can't find them.

Lena noticed this when he was instructing Dana to learn magic before he asked Claire about it.

"So you'd better hire someone else to make clothes or something."

Dana is not modest. She doesn't understand how she can make such complicated clothes as an ordinary student?However, she is very interested in the clothes on the design drawings of Lena. After all, girls still like beautiful little skirts. In this hot summer, it's really hard for these adolescent girls to wear mage robes.

"But Claire told me that you can tailor and make clothes in private."

On the one hand, he wants to refer to the aesthetics of girls of this age, and at the same time, he hopes Dana can optimize the design from the perspective of production. On the other hand, he also wants to cultivate Dana's ability in this aspect, which may be useful in the future.

"Well, I won't have to do the test papers every Sunday. How about a day off for you?"

In the face of Dana who refuses, Lena uses her trump card.

"This..."

Dana immediately wanted to nod her head and agree to sign the contract, but after a moment's hesitation, she felt that she could not be so spineless.

"Saturday and Sunday."

"Deal!"

Almost without thinking, Dana stood up, took Lena's design and began to examine it.

What could be happier than not having to write math papers on Sunday?

No homework for two days on the weekend!

It's no problem to let Dana do something indescribable even if she can take a breath from the oppression of mathematics!

She looked at the design and then picked up the quill.

"It's better to use rounded corners for the design here, but the colors are not quite right..."

looking at Dana, who is focused on Revising the design draft, Lena can't help smiling at the success of the plan.
