At the call of Kaka, the fairy king, the fairies who had taken refuge returned from the white ball in the library, and following Kaka's instructions, they set about cleaning up the castle that had become a ruin.
In addition to finding usable items from the ruins, this is also to pay Yang Yu the reward he deserves.
Watching Li Yan and the others leave, Yang Yu naturally started talking about the topic of remuneration.
Yang Yu said that compared with material rewards, he still hoped to get spiritual satisfaction more, and then mentioned the white ball placed in the skyscraper library.
The white ball can obtain the location of the book based on the information in the prompts, which cannot be accomplished simply by using manpower.
Kaka also told Yang Yu the operating mechanism of the white ball without reservation.
If the white ball did not have the support of the fairies and the fairy treasures, it would ultimately be just an ordinary magic device.
Every time a book is stored in the library, the content and storage location of the book will be transmitted to the fairy's secret treasure through the white ball, saved as data, and turned into one of the huge databases.
Whenever someone searches, the fairy will transmit the information obtained back to the fairy's secret treasure, which will be processed by the secret treasure.
The secret treasure will search according to the keywords in the book, such as the book title, introduction, title, and content.
After finding the matching books, the reserved location information will be given in turn.
These messages will then be transmitted back to the fairy's brain, where they will filter and organize them, write them on a white ball, or transmit them to the brain of the person who is looking at them.
Hearing this, Yang Yu naturally thought of obtaining all the knowledge he needed through the fairy's secret treasure.
So, he made a request to Kaka, the Fairy King, hoping to gain the knowledge he wanted through the Fairy's secret treasure as a reward.
After thinking for a while, Kaka finally decided to agree to Yang Yu.
Although the knowledge stored in the secret treasure comes from the Library of All Things, over the years, the work of maintaining the fairy treasure has been done by the fairies, and the Library of All Things has never paid anything for it.
Perhaps in the eyes of the Library of All Things, putting knowledge into the goblins' secret treasures is equivalent to sharing knowledge with the goblins, so they don't have to pay anything for it.
In fact, the effort the goblins put into maintaining the secret treasures far exceeds the imagination of the Library of All Things.
Since the library believes that the knowledge they provide is rent, there is nothing wrong with sharing this knowledge belonging to the goblins.
Therefore, Kaka did not reject Yang Yu and let the fairies clear the way for him.
The goblin rescued by Yang Yu worked particularly hard to move the rubble, and thanks to this, the rubble of the castle was quickly moved.
A red square piece of glass was revealed in the center of the castle, which was the only way to the place where the secret treasure was located.
Kaka's figure directly penetrated the square piece of red colored glass. He injected magic power from the inside, opened the square piece of colored glass, and revealed a staircase leading downwards.
Following Kaka all the way down, Yang Yu and the others came to an empty room. In the middle of the room, several green vine-like things were entwined with each other, holding up a crystal ball that was glowing white.
That is the secret treasure of the fairies, and the fairies call this secret treasure "All Knowledge".
The light emitted by the white crystal ball has a heavy feeling like gas, illuminating every corner of the room.
Bai Jin stretched out her hand and could feel that the crystal ball was emitting the same magical power as Kaka, but this magic power was even more intense and abundant.
But even though it is so rich and abundant, the existence of this crystal ball cannot be felt at all from the outside.
Bai Jin couldn't help but wonder how the fairies did it, but she didn't say anything.
Such confidential information would probably not be told to her since her contribution was so small.
Kaka said: "What knowledge do you want to inquire about? You are welcome, just go ahead and search."
Iyas looked around, wanting Yang Yu to quickly search for clues about her brother, but she saw Yang Yu first took out a few sheets of paper covered with dense writing, and then took out a brand new booklet.
"Do you have so many things to check? I think you can wait until you find my brother before you come here to check. The most urgent thing now is to find my brother."
The clue was just around the corner. Iyas couldn't suppress her excitement after all. She grabbed Yang Yu's shoulders and shook him hard.
However, Yang Yu just pushed Iyas's hand away and said in an orderly manner: "I can understand your feelings, but that can't be an excuse for recklessness. We must investigate everything step by step to ensure that we are safe on the way."
Iyas wanted to say something, but Yang Yu continued,
"It will probably be a long time before we return from the Library of Everything this time. During this period, we will definitely encounter many difficulties. You don't want our journey to end halfway, right?"
Iyas bit her teeth lightly, stopped talking, turned away, and sulked alone. She could only keep convincing herself in her heart to accept Yang Yu's decision.
Just as Iyas was about to check it out herself, Kaka added:
"Although the fairy's secret treasure can serve multiple people at a time, if you want to check the specific content, it may cause information input and output to be stuck, and others may find out that we are looking up the contents of the library's books. Therefore, I still hope that you can check them one by one."
"I understand. It's enough for me to be the only one here.
There's not much point in you just staying here and watching.
Bai Jin, Iyas, I've thought about it and decided to send you two back to the Library of All Things first. Iyas will continue to learn about humans from the library, and Bai Jin, you will continue to learn magic knowledge from Tiko and Li Yan, and try to master new skills as soon as possible."
After that, Yang Yu only asked a question about the fairy's secret treasure through Kaka, the fairy king.
Then he turned and left, planning to first deal with the Library Special Countermeasures Committee that was eyeing them covetously, free Yingluo and Lotkar, and then return to the Fairy Kingdom to search for the knowledge he wanted.
Since you can copy the knowledge you need from the electronic version, you don't have to go through so much trouble to please the library elders, take books out from the bookshelf and search one by one.
Kaka allowed Yang Yu to leave the Fairy Kingdom and return later. There were still a lot of quotas left to deal with the black energy, so there was no problem for Yang Yu to travel through the barrier several times.
The few people reached a consensus, and Yang Yu and his friends left the basement where the secret treasure was and came to the open grassland.
The magic power of Kaka, the Fairy King, enveloped them and turned them into a cluster of light.
Kaka pushed forward, and his magic power took Yang Yu and the others through the thick clouds, through the fairy's barrier, and into the white ball in the library.
On the other side of the white ball, the Special Countermeasures Committee of the Library of All Things had been waiting for them for a long time.
