The peaceful days flew by, and in the blink of an eye, the end of the year was approaching, and the students' courses had basically entered the review stage. Winters in the capital are very cold, and the students are still living in tents. The dormitory building has long been leveled by their battles, and construction is still intensifying. The main building is basically completed, but the supporting decoration is not so easy.

As the principal tried to cooperate with the city circle, he added some functions to the dormitory. For example, it can automatically roll call, automatically check the situation of people, and even listen to student conversations if necessary. To this end, the students and teachers of the Department of Architecture worked together with the engineering team to directly consider their own dormitory as a topic.

As a result, other students have been forced to live in tents and endure the cold of the capital. At the same time, the tents are all on the playground, which makes it difficult to carry out many armed sports because of the field problems, which can be regarded as stealing laziness and not being able to do other recreational sports, which can be regarded as both pros and cons.

The orc students have converged a lot, and because of the cold weather, their desires have also decreased a lot. But even so, their results were as bad as ever. The result of expelling all the eighth-order powerhouses last time was equivalent to expelling a considerable number of people with good grades.

But I don't expect them to have any good results, as long as they don't make noise, thank God. And as the contact time increases, teachers and classmates can also discover some rare advantages of orcs. For example...... They're so foolish, and ...... There is plenty of superiority to be found in them, and so on.

In fact, after that fight. The disdain of the Terran students for the Orc students has almost reached its peak, and even most of the teachers have a big opinion about them, but they can't say it because of their identity. Anyway, as long as they don't cause trouble at the moment, the Terrans won't take the initiative to cause trouble.

It's just that when I think that these people may also graduate, many people are unconvinced. However, it is only the first semester, and it is still a long time, so I can wait and see.

Kevin is still a librarian, and he no longer attends lectures because the students' courses are basically in the revision phase. As a person who never does homework, he also learns very freely. After all, there is no realistic exam pressure, and Kevin occasionally becomes lazy. But once you decide to start studying today, you must understand the problem until you understand it.

As for Little Spoon and Sain, of course, they still manage the orc students as temporary workers. They still maintain the tradition of going to the principal's office every day and queuing up to call "Grandpa Principal". But as they got better and better, Spoon and Sain gradually became more relaxed.

The three of them will go to visit the crows together when they have time, and if they don't have time, Kevin will go alone, basically once a week. The crow is doing well, although he is in a cage, but at least he is cheerful. I also had a good chat with the female inmates in the prison, and Kevin almost had to talk for more than half a day every time he went.

From high-end magical knowledge to recent current news, it covers almost everything. The crow has nothing else to do in prison but to read non-stop. For a while, a person and a bird started talking, and all the high-end names popped up, which stunned the prison guards on the side.

Recently, the crow finally had a new invention, he felt that as a bird has no expression, and when he speaks, it is too vivid, so he invented an expression hat.

Of course, he couldn't make it himself in the cage, he just drew the drawings. There are some delicate magic arrays in the hat, which can be directly controlled with the spiritual power of birds. Then a spring and an expression sheet of paper are set in the hat, and as long as necessary, the bird can control the small mechanism in the hat through mental power, and then open through the upper end of the hat to pop the expression.

The crow designed three expressions, an exclamation mark, a question mark, and an ellipsis. To put it simply, if the crow wants to express horror, he only needs to move his mental power and an exclamation mark pops up on his hat.

"The Terrans don't need that," the raven began, "and the Terrans have a wealth of facial expressions. For example, if you want to be speechless now, you can do it directly with facial expressions, without wearing a hat and then popping an ellipsis on the hat. ”

Kevin: "......"

"Not for crows, not for parrots," sighed the crow, "and hopefully there is some market for this thing." ”

"I'll take it back and study it. Kevin immediately got up and left.

The crow shouted from behind, "I invented it!"

"Rest assured, I will state this repeatedly. Kevin hurried away.

Back at school, Kevin immediately gathered materials to prepare for the experiment. The crow only drew a drawing, and it would take a lot of experimentation to succeed. Strictly speaking, only when the experiment is truly successful can it be considered a real invention.

Magic crystal grinding and carving, magic circle carving, magic testing, and even the simplest hat shell making, if Kevin were all left alone, it would definitely not be done in a month. Fortunately, the school has sufficient resources, and Kevin has brought in a few excellent students, who are also willing to complete this novel invention for Crow.

A week or so, this thing that looked a bit like a magic hat was made. I found a few parrots to try them on, but the results were not ideal. If you want to pop up the emoji, the mental power consumed is too great, at least for the average parrot. Almost with great effort, he finally flicked an ellipsis out, and then gasped for breath on the side.

This is obviously not practical, maybe it is acceptable to the crow, and it must be easier for him to have stronger mental power. But if you want to promote it, you need more improvements. This kind of improvement is not so easy, it requires a lot of complicated material testing, and many times it is almost a matter of luck.

Even so, Kevin sent the hat to prison. After the crow brought it, it was very excited. Exclamation marks, question marks and ellipses were played in turns over the head, only with a slight regret: "It's a pity that the head is a little heavy." ”

"Don't you think three expressions are too few?" Kevin reminded.

The crow thought for a moment, suddenly popped up an exclamation mark, and then pretended to be surprised and said, "It's terrible, there are fewer three expressions?"

Kevin: "......"

The crow pops up a question mark, indicating confusion.

Kevin: "......"

Then the crow also pops up the ellipsis.

"Okay, I'm leaving, you play slowly. Kevin really didn't know how to answer, and when the time was about right, he left.

However, when Kevin returned to school again, he was surprised to find out. The emoji hat, which is difficult to promote among parrots, has become inexplicably popular among students.

The hat worn by the Terran is even simpler, no magic crystals are needed, and the expression can be changed manually. This is something that is difficult for birds to do, and neither claws nor beaks are very convenient, so crows invented hats controlled by mental power. But for the Terrans, this is not a problem, and even the Terrans have a large head and can put more expressions.

Kevin saw the two students chatting and laughed heartily. One student suddenly said, "Wait, let me change my expression." ”

Then I saw him touch the hat on his head, and a funny one popped out of the hat, and then he continued to laugh. Another student followed along, and a funny one popped up. Two students put two funny heads on their heads and then laughed at each other.

Kevin was surprised for a long time on the side: "Young people really know how to play." ”
