Chapter 383

As soon as Lena's finger touched one of the green boxes with the words "find", the whole picture immediately changed into a pattern with only one blank line.

Gently touched that line of blank, at the bottom of the screen, appeared a pile of dense text.

Ashluya, who is located nearby, soon found that these are buttons made of light, with different words on them.

"Because handwritten words are difficult to distinguish for various reasons, this device uses a fixed keyboard input, well, just like a typewriter used by ordinary people."

Lainer explained that in newspapers run by ordinary people such as daily price, the input of words relies on a machine called typewriter. People type words on the keyboard and press the key to push the lever to make the corresponding words printed on the paper. In the hands of skilled typists, this input method is far more efficient than handwriting, if it is pure recording The situation is not even lost to the mage's automatic notes.

In some new aristocratic and merchant families, learning to use typewriter has become a compulsory course for children, so many students present are not unfamiliar with this keyboard.

With that, Lena typed the title of the book, introduction to alchemy, and then pressed enter.

Waiting for about three seconds, the screen suddenly changes, a string of text to replace the previous blank, appears in the middle of the screen.

As you can see, this is a list of different versions of an introduction to alchemy. This basic book on alchemy compiled by Mr. hornheim has been revised many times due to the development of alchemy. The latest and the biggest change is that in the month of dew, Lena's electrolytic water experiment has become a classic example in the textbook, while the original four elements theory has been changed It was reduced from a big chapter to a chapter in the history of alchemy.

Lena selects the latest edition and clicks open to see how the book is in the library.

There are ten books on loan, three in the library, a total of 13.

At the same time, this page can also see the brief introduction of the book, and even the contents of the first part of the chapter. It is a very convenient function for students who do not know what books they need and can only master a general range.

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

With a wave of his hand, a slightly heavy book, the latest edition of an introduction to alchemy, came to the bookshelf in the distance.

He skillfully pressed the back button and went back to the original page. This time, Lena hit the borrow button.

After pressing this button, the screen became blank, and there was no text for a long time. When other students were confused, Lena put this heavy "Introduction to alchemy" on the stone.

Drop -

the stone gives out a beep, and then the original blank screen immediately shows the relevant information about the introduction to alchemy, and there is an option to borrow it at the bottom.

When Lena presses the borrowing button, the screen jumps again. This time, it prompts him to put his ID card on the screen. Lena takes out his badge and swipes it, and his message appears again.

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

Lena said that many students bowed their heads to confirm the school badge on their uniform chest.

This kind of magic used by the school emblem has been put into use. It is a simple sign of identity. Only holding the school emblem will not be surrounded by the school's defensive array alarm. As for dining in the canteen and other functions, it is not uncommon. The mages of the mechanical department have developed many corresponding magic long ago.

This is the reason why Lehner can develop a decent database so quickly. He doesn't need to build a computer system from scratch. He just needs to introduce the characteristics of black lamprock into the original mechanical magic system of the world, and use the magic conduction characteristics of black lamprock to realize some functions that are difficult to be realized by magic.

It's just like the database around lainer. If you are a high-level mage in the mechanical department, you can use pure magic to create something with similar functions in a certain amount of time. However, the complexity and materials consumed are far beyond the cheap black lamprophyre.

Incidentally, in order to ensure the supply of raw materials, Lena took a detour on the way back from the rainbow tower to check the production situation of the heihuangyan mine. By the way, he bought several mines with his own money. Thanks to the fact that the value of this kind of rock has not been discovered, Lena has now semi monopolized the supply of raw materials for heihuangyan, and has not spent much.

Next, Lena demonstrated the process of returning the book again. Similar to borrowing, just sweep the book and then sweep the badge. The returned books are put aside and put back on the shelf by alchemists.

Although it's a simple library management system, it's completely mechanical. For those students who are used to seeing magic light, it's very novel. In particular, this interface has a kind of simple and cold aesthetic feeling, which is completely different from those fancy styles.After that, Lena gave the machine to the students and watched them try out the library management system with a happy smile.

This is just a test object, which is used to test the most basic functions. If it can guarantee that there will be no accidents, then Lena can devote himself to the next development.

The convenience of rainbow tower makes Lena feel deeply. Under the power of legendary mages, even ordinary mages can enjoy an excellent life experience. At the same time, their application of such convenient tools is extremely simple.

This made Lena think of a saying that if primitive people were given a hard alloy, they would only be used to make spears and swords, but if modern people were given the same thing, they would develop brilliant industrial civilization.

So, it's not that these legendary mages don't have enough imagination, but that they don't have enough accumulation. At this point, Lena's identity as a passer-by gives him endless advantages.

Lena's long-distance communication tools are not only used to transmit information. He can set up academic forums to promote the exchange of mages all over the mainland, develop online shopping to exchange the existence of each half plane, and even use them to make games to bring you a new way of entertainment.

However, all this requires him to complete the prototype first.
