Meet the principal

Welcome, please remember the address of this website: , read on your mobile phone so that you can read the latest chapter of the novel "Meet the Principal" at any time...

As soon as Reiner's finger touched one of the green boxes with the word "Search" written on it, the entire screen immediately changed into a pattern with only one blank line.

After lightly touching the blank line, a dense pile of text appeared at the bottom of the screen.

Asilua, who was nearby, quickly discovered that these were buttons made of light, with different words on the buttons.

"Since handwritten text is difficult to distinguish for various reasons, this device uses a fixed keyboard input, um, just like a typewriter used by ordinary people."

Reiner explained that in newspapers run by ordinary people such as the Daily Press, text input relies on a machine called a typewriter. People type words on a keyboard, and the keys push levers to make the paper The corresponding text is printed on the top. In the hands of a skilled typist, this input method is far more efficient than handwriting. If it is a pure record, it is not even inferior to the mage's automatic notes.

In some new-school aristocratic and merchant families, learning to use typewriters has become a compulsory course for children, so many students present were familiar with this keyboard.

As he spoke, Reiner casually typed the title of the book, "Introduction to Alchemy", and then pressed Enter.

After waiting for about three seconds, the screen suddenly changed, and a string of text replaced the previous blank space and appeared in the center of the screen.

As you can see, this is a list of different versions of "Introduction to Alchemy". This basic alchemy book compiled by Lord Hohenheim has been revised many times due to the development of alchemical spells. The latest one is also the most modified. Once during the White Dew Moon, Reiner's electrolysis of water experiment became a classic example in the textbook, and the original theory of the four major elements was reduced from a large chapter to a chapter in the history of the development of alchemy.

Reiner selected the latest edition and clicked it to see the status of the book in the library.

Ten copies are on loan and three are in the library, making a total of thirteen copies.

At the same time, you can also see a brief introduction to the book on this page, and you can even see some of the chapters at the beginning. This is a very convenient feature for students who don’t know what books they need and can only grasp a rough range. .

"This is the most basic search function. Of course, this system also has borrowing and returning functions."

Reiner said, and with a wave of his hand, a slightly thick book flew from the distant bookshelf, which was the latest version of "Introduction to Alchemy".

He skillfully pressed the back button and returned to the original page. This time, Reiner clicked the borrow button.

After pressing this button, the screen became blank, and no text appeared for a long time. When the other students were confused, Reiner placed the heavy "Introduction to Alchemy" on the stone.

drop--

The stone buzzed, and then, information about the "Introduction to Alchemy" appeared on the originally blank screen, with a borrowing option at the bottom.

Reiner pressed the borrow button, and the screen jumped again. This time, he was prompted to put his identification on the screen. Reiner took out his badge, swiped it lightly, and his information appeared again.

"This badge corresponds to the school badge issued when you entered school. You must have used it when eating in the cafeteria."

Reiner said, causing many students to lower their heads and confirm the school badges on the chests of their uniforms.

The magic used in this school badge has been put into use. It is a simple sign of identity confirmation. As long as you hold the school badge, you will not be surrounded by the school's defensive array and call the police. As for functions such as dining in the cafeteria, it is not uncommon. Mechanical Department Mages have developed many corresponding spells a long time ago.

This is also the reason why Reiner was able to develop a decent database so quickly. He did not really need to build a computer system from scratch. He only needed to introduce the Black Huangyan to the original mechanical magic system of this world. Characteristics, just use the magical conduction characteristics of Black Huangyan to realize some functions that are difficult to achieve simply with magic.

Just like the database next to Reiner, if he is a high-level mage of the mechanical system, he can use pure magic to create something with similar functions after spending a certain amount of time, but the complexity and the materials required are much higher. It is not comparable to the cheap black Huangyan.

By the way, in order to ensure the supply of raw materials, Reiner took a detour to check the production situation of the Black Huangyan Mine on the way back from the Rainbow Tower. By the way, he bought several mines with his own money. Fortunately, the value has not yet been discovered. Reiner now has a semi-monopoly on the raw material supply of Black Huangyan without spending much money.

Then, Reiner demonstrated the process of returning a book. It is similar to borrowing. You only need to scan the book and then scan the badge. The returned book is put aside and will be placed back on the bookshelf by the alchemy creature on a regular basis. .

Although this is a simple library management system, it is completely completed by machinery. For these students who are used to seeing the light of magic, it is very novel, especially this interface, which has a certain simple and cold beauty. Completely different from those fancy styles.

Afterwards, Reiner handed over the machine to the students for use, and smiled happily as he watched them rush to try out the library management system.

This is just a test product, used to test the most basic functions. If it can be guaranteed that no unexpected situations will occur, then Reiner can devote himself to the subsequent development.

Reiner was deeply impressed by the convenience of the Rainbow Tower. Under the power of the legendary mage, even ordinary mages can enjoy an excellent life experience. At the same time, their application of such convenient tools is extremely rudimentary.

This reminded Reiner of an idea. If primitive people were given a hard alloy, they would only use it to make spears and swords, but if modern people were given the same thing, they would be able to develop a brilliant industrial civilization.

Therefore, this is not because these legendary mages have insufficient imagination, but because they have not accumulated enough. At this point, Reiner's status as a time traveler gives him endless advantages.

Reiner's acquisition of tools that enable long-distance communication will not only be used to transmit information. He can establish academic forums to promote exchanges between mages from all over the continent, and develop online shopping to communicate the possessions and possessions of various demiplanes. It can even be used to make games, bringing a new way of entertainment to everyone.

But all this requires him to complete the prototype first.
