In the special interrogation room, Yang Yu enthusiastically promoted the textbooks that he retired from his classroom many years ago.

After riding on the light ball that Kaka made for them, Yang Yu settled all completed tasks and used up all the lottery draws.

Today, he was also as always, being hung up and beaten by the goddess of luck, and there were more inexplicable things in the warehouse.

In particular, he also pulled out a whole truck of farm fertilizer, and the broken system implied him to go home and farm quickly.

Among these broken irons, the only one that can be seen is a laptop, but there is no network in this world, nor the current that supports its operation. This computer is also a five-digit, and can only be used to knock walnuts.

Perhaps, it's good to have a foot pad.

As for the guaranteed skill obtained in the mission of the source attack, Yang Yu drew out a skill called. It was very powerful just by looking at the name. In fact, this is just a very ordinary attack BUFF, and can only increase the damage of sword strike by 10%. It is also useless to Yang Yu, the tank.

Yang Yu planned to sell all kinds of snacks to Mr. Chirom, all the books to the Library of All Things, and all the useless things were in the box.

As a member of the library, the elders of the Special Countermeasures Committee have a strong interest in the books in Yang Yu's hands. Ancient civilizations are all ancient legends that only exist in books. No matter who they are, they want to peek at the tip of this ancient iceberg.

There were even several elders who could no longer suppress their excitement, hoping that Yang Yu would read the book in his hand immediately.

Give others a taste of the sweetness, but it is quite common marketing methods. Of course, Yang Yu was very happy to draw out a physics book and raise his hands towards the elders.

An invisible suction force pulled the book in Yang Yu's hand and fell into Valorna's hand. Many elders leaned over secretly.

Barona turned slightly to let the light behind her shine on the book. The smooth cover reflected colorful colors, and exquisite pictures were painted on the cover, paired with text that was completely incomprehensible.

When I opened it, I saw that the flat and soft paper made me feel comfortable, and the words written on it were extremely neat.

It's completely different from the books they should have in this era.

The elders around them tried to read this book, but even if they had a wide range of knowledge, they had never seen such strange words before. They couldn't understand that book at all, so they could only look at Yang Yu helplessly.

Taking this opportunity, Yang Yu immediately began to brag about how terrible the Light of Destroy God was, saying that if he hadn't arrived at these books earlier, he would have been ruined by the Light of Destroy God.

Later, Yang Yu said that he also received some inspiration in the ruins and became able to understand some of the texts in the book.

It is precisely because of this that he realized the specialness of these books and wanted to sell these truly valuable books to the Library of Everything.

In order to prove that he had indeed understood the above content, Yang Yu took out a thick and long glass rod and stuffed it into the soft cotton cloth. He put his hands up and down, gently squeezed it up and down, rubbed it hard, triggering a fatal rhythm, allowing the glass rod to easily absorb the pieces of paper he had prepared in advance.

Several elders from the library couldn't help but make a sound.

"What magic did you use? The paper piece was washed directly on the stick... Why can't we feel the magic fluctuations?"

"Because this is not magic." Yang Yu smiled softly.

"Not magic? Then what?" the elder asked.

"Reason. The principle of existence in this world. Everything in the world, from the giant dragons in the sky to the ants and crawlers on the ground, must follow certain rules and follow what they do.

The set of books you read now is the book that civilization tries to reveal the truth of the world.

As far as I can see, the ancient civilization did not possess such convenient magic as we did, but they still rely on reason to build glory and create many things beyond your imagination.

If you can understand it thoroughly, it may change your view of the world."

Yang Yu was very wise, but the elders tilted their heads a little reluctantly. After Yang Yu said so much, they still couldn't understand it. Even if the words above were vivid and they couldn't recognize one of them, they couldn't understand the knowledge mentioned above.

Just as if he had penetrated the thoughts of the elders, Yang Yu smiled and took out the math textbook and a thick dictionary.

"The set on my left hand is the necessary knowledge to solve the truth, and it is called mathematics.

The thick book on my right hand is called a dictionary. Your library must also have books to teach others to read and read, and the dictionary in my hand is a necessary teaching material for teaching people to read and read in that era.

The library of all things gathers talents [Biquge www.bequge.xyz], and it should not be difficult to find a linguist who is very good at ancient Chinese.

As long as you hand over this book in my hand to him and let him understand it thoroughly, you can interpret other knowledge in the book.

In addition to this, I have some other books here, and I recommend them most in addition to these three books..."

Yang Yu talked endlessly about how good the books in his hands were, and told everyone here that if they missed this village, they would not have this store. If the Library of Everything does not want to buy this knowledge, he would have to find another place.

After reading the books in his hand, the elders of the Countermeasures Committee looked at the books in his hand with a fiery look. They knew the value of this thing better than anyone else.

"The value of books is undeniable. But why do you conclude that these books can help our library of everything and solve the problems that have always troubled us?"

Pretending to be a memory, Yang Yu's every word is sonorous and powerful.

“In the era I saw, everyone had extensive knowledge, and people could learn all kinds of knowledge without leaving home.

Even knowledge as huge as the Library of Everything requires only a small box to pack and take away, and there is no need to build such a huge library.

I now provide your books, which is to open the door to that era, and it is likely to be the inspiration left to subsequent civilizations when ancient civilizations were destroyed.

If you can understand the knowledge thoroughly and use it freely.

A new era will come.”

As he said that, Yang Yu took out the system and pulled the laptop.

"What I said in my words can hold all the knowledge of the library, this is this thing.

Unfortunately, I don’t know how to use this box. It seems that there is a lack of some energy that can run it. Perhaps that energy is hidden in these books.

Whether what I said is true or false will be left to you to judge.

I believe this thing can only play its best role in your hands than in my hands.”

Looking at Yang Yu's black box in his hand with nature, the people on the Countermeasures Committee showed a different look in their eyes, and they did not hesitate.

"Talk about your terms, what do we need to pay for you?"
