Chapter 382

The news of Lena's promotion has spread all over the mainland since the High Council. While people marvel at the talent of this young man, they also have a lot of interest in the things around him. Since the fall of the moon, there has been an endless stream of people visiting crescent college, and students' curiosity and discomfort have become commonplace.

At the same time, the girls' longing for their headmaster has become more intense. Just imagine, who doesn't like a handsome, gentle and talented young gentleman.

It's a pity that Lena is usually busy with research and affairs, so it's hard to show his face in front of the students. Now think about it, in the first class at the beginning of school, it may be the closest time for these students to come to Lena. Many people sigh because of this, and regret that they didn't show themselves well at that time.

Hathaway and ashluya, who were named to answer questions at that time, became the envy of many girls in a sense. These are trivial matters.

Ashluya pulls Hathaway to the front of the crowd and sees Luna Ian gray, the president of new moon college, and their math teacher, Sur, standing in front of a big black stone, as if ready to introduce it to the students.

"Cough, please don't be excited. I'm here today to introduce the latest equipment of our library."

Lena cleared his throat and said that he didn't expect that his students were so fond of learning. Even on the rest days, there were so many people in the library. He thought that after the bombing of self-study in the evening, self-study in the morning and the monthly examination, these little girls would be tired. But now, it seems that the sea test tactics have some effect.

However, many students' eyes were focused on themselves rather than on the new equipment, which made Lena feel a little uncomfortable, like a prey being watched by a hungry wolf.

He took a step to the side and exposed the huge stones behind him. This is the main character today.

"What is this?"

At this time, the students' attention gradually turned to the huge black stone. From the outside, this thing is ordinary, and there is nothing that can show the purpose. When it is connected with the library, they don't know how to spread their thinking.

"Dear students, when you are in the library, do you often encounter the situation that the books you want to borrow are borrowed by others, but you don't know when the other party will return them, or the books are randomly placed and can't be found in the original bookshelf, or you don't know whether there are some problems with the books in the library of the school?"

Lena asked, his words made the students feel the same. Although some crystal worms are bred in the library to serve as guides, the information of these crystal worms is not updated immediately, and the number is limited. For example, when a large number of students are concentrated in the library today, the number of crystal worms is far from enough.

This is not because Lena is not willing to spend money to raise more of these little guys with good memory, but because the food of crystal worms is biological drowsiness. On weekdays, the drowsiness of library students is enough for a certain number of crystal worms to live normally. However, if there are holidays or very few Librarians, these crystal worms will starve. It can last for a day or two Therefore, if the time goes on, these crystalloids are likely to starve to death.

In this case, most schools plan to introduce the crystal bug into the animal pen to absorb the sleepiness of those magical creatures. Of course, this kind of behavior can only maintain the normal daily income and expenditure. After all, the crystal bug sucks away the fatigue, not the real fatigue. In short, it has the same effect as coffee. Long term use not only can't maintain high spirit, but also can save money I'm tired.

The number of crystal worms in each library has been carefully calculated, which is just able to maintain its operation. Therefore, the number of crystal worms in the library of new moon college can not be wantonly increased.

Because of this problem, combined with Lena's recent research, this swarthy stone came into being.

"In order to solve this problem, Mr. sur and I specially developed this device, which is called database."

"Database..."

Hathaway repeated this strange sounding word. For some reason, it seemed to have some magic power to attract her attention.

"Let's take a look at the function of this directly."

Said Lena, while gently pressing a little on the slope above the black stone.

Buzzing -

a subtle magic wave diffuses, and suddenly lights appear on the huge black rock which is no different from ordinary stones.

The green light converges on the stones, forming a familiar text for students.

"Crescent college library inquiry system?"

Ashluya read out the largest text at the top and tilted her head.

"First of all, we mark all the books in the library of crescent college with magic marks. This is the setting that all libraries will do to prevent the loss of books. But in most cases, this magic mark is only used to prove that the books are owned by the library and to track the location in special cases."Lena didn't know when he had one more book, he explained.

"The library query system actually uses this magic mark. We add a special characteristic value to the magic mark of each book. By comparing it with the record, we can confirm whether the book belongs to the library, and at the same time, we can track the borrowing of the book."

In fact, similar work can be done by magic. In the rainbow tower high level school of magic, there is a very sophisticated and complex array that controls all the books in the library. However, this array is designed by legendary mage, Mr. Alan von Norbert Reinhardt of the Department of mechanics, and it costs as much as the paper review system of the rainbow tower.

Most of the structure of the database used by Lena is BlackRock. Lena uses these special rocks to create the most basic integrated magic circuit system, just like the one played in the game.

In the process of research and development, Lena also found that the teacher she recruited, Sur, who was a little confused, had some attainments in mathematics. After all, she was the first person to discover the value of cyris' thesis. Her head was flexible, but she was too straight to be suitable for the workplace.

With the help of the algorithm designed by Sur, the first test object was soon completed. Lena made a database program by using simple programming means, which is quite simple, about equal to the level of novice programmers on earth. Because there are many places where magic can be used, it is more convenient.

The final result is the new moon college library inquiry system, which has simple input, output, storage, logic operation functions, or touch screen, but it's a pity that Lena's research on materials has not made progress, and the integrated magic circuit is still in this huge volume, which can't be reduced to the palm size.

"Let's experiment."

Then Lena reached out and touched the green words on the black slate.
