After wandering around the library with Oas for a while, Yang Yu quickly lost interest.

There are many books, but there is no one that Yang Yu is interested in at all.

Although the knowledge here may come in handy one day, accumulating so much knowledge is a thankless thing in itself.

Unless you want to pursue a related profession, a lot of the knowledge you learned will only make people bald, and a sunset in the Mediterranean is staged.

Besides, when he really remembers this knowledge in his mind, the daylily will probably be cold, and maybe the devil will hit the doorstep and celebrate the conquest of the world.

"Sure enough, if you want to gain that knowledge, you must become a senior member of the library."

I don’t know if there is any special mechanism in this library. If you can jump back and forth between each other on the floor through a secret channel, or directly find the knowledge you want through the omniscient magic mirror.

It’s a pity that it’s just thinking about it.

Yang Yu knew very well that with his luck, he could only find those fancy things by searching with carpet style.

But people know whether those things are hidden in a certain book. If they are really in the book, they will probably drown in the ocean of knowledge before they find it.

Even if you really find it, you will be discovered soon and you will be discounted by someone using those things in the library of all things that are gathered in experts.

Therefore, Yang Yu finally decided to adopt the plan that had been decided long ago and not make any temporary changes.

"Speaking of this, how can such a high floor be connected quickly to each other?"

After walking for so long, he didn't see anything like a staircase, and Yang Yu secretly complained to himself.

The skyscraper's appearance is like a skyscraper. If there are no elevator-like props, just climbing stairs and climbing to the top floor, you will be exhausted.

Just as Yang Yu thought so, the direction of the extension of the bookshelf suddenly stopped and they arrived at the center of the first floor.

Four thick columns occupy the four square corners in the center, expanding a vast square area. These columns are coiled with spiral upward steps, leading to the second floor.

In the center of the square area is a huge white sphere, with the top just up to the ceiling, and one-third below it sinks into the ground.

Several library members approached the white ball and placed their hands on the white ball. Ripples appeared on the white ball without warning. Several magicians passed through the white ball, wrapped in the white ball, and disappeared into the white ball.

With the experience of the last time, this time when facing the sudden disappearance of the person in front of him, Oias was obviously much calmer. "Can the weird device send people to another place like yesterday's teleportation magic?"

"Probably, but other possibilities cannot be ruled out."

Getting closer to the white ball, Yang Yu put his hands on the white ball like those magicians.

As soon as Yang Yu's hand touched the white ball, the surface of the white ball seemed to be blown by the breeze, and ripples gently appeared.

Without warning, a voice suddenly rang in Yang Yu's brain, "Select the number of layers you want to go to, or say the knowledge you want to query."

This white ball is used as a prop for a high-speed elevator in the library? By the way, is it competent for book query?

In order to verify the thoughts in his heart, Yang Yu said the number of layers he wanted to go to.

“The eleventh floor.”

Currently, Yang Yu is an ordinary member of the library and is not qualified to go to the eleventh floor. He asked this, just to hear how this white ball answered him.

"Sorry, except for the first layer, the positions I can transmit are all multiples of five. Please choose again."

“Fifteenth floor.”

"Sorry, you have insufficient authority at present and cannot reach the fifteenth floor."

As a natural result, Yang Yu fell into deep thought.

How do you judge whether I have permission to do this thing? Is it because of the card I have on me? Or was it a special recognition magic when I came in?

Yang Yu checked the status bar and there was no magic-marked icon on it, which means that the card on his body is more likely.

"Send us to the tenth floor."

"receive."

As soon as he finished speaking, a mysterious force burst out from the white sphere, leading Yang Yu into it. Yang Yu's eyes were covered in white, but he didn't feel any discomfort.

The voice came again, "Telection is in progress, please take action after receiving the instructions."

After about a second or two, the white in front of Yang Yu and the others became thicker, and then it became thinner again at an extremely fast speed.

"I have reached the designated floor. Please turn around and walk out of the teleportation device. Thank you for your use."

Turning around as the instructions, Yang Yu saw a transparent arc, which was more like a thin layer of bubbles than a glass wall, as if it was broken with one poke.

Through this "bubble", you can see the situation outside clearly, and you don't have to worry that those who come in will collide with those who go out.

With this kind of prop, it is easier to shuttle between floors than to elevators.

When he arrived at the tenth floor, Yang Yu turned around and looked at the huge white sphere behind him. The transmission device on the tenth floor was one size smaller than the first floor. The lower half did not penetrate into the ground, but was fixed in a metal groove.

Compared to the books in the library, Yang Yu is more concerned about this device.

After testing the transmission function, he is naturally testing the search function. As we all know, the search system is used to make a mess.
