"On the Idea of ​​Using Conflict Circuits to Create Explosions".

Huh?

"On the Self-cultivation of Great Engineers"?

Me? Why don’t you know that big engineers have self-cultivation?

Yi Lin looked at the signature.

——"by Albus Perciva Woolflick Brian Dumbledore."

That's all right.

Yi Lin ignored this book without any use.

"It seems that I have almost seen it."

Yi Lin's fingertips passed by the covers of books, feeling boring.

He has seen all these.

Although many of the contents are not fully understood, Yi Lin used his terrible memory to compose these contents by rote and slowly digest them later.

Yi Lin raised her head and looked at the bookshelf in front of her that could not see the end, and was speechless.

You said that you are a good turn-based RPG online game, and it would be fine if you use this method to convey knowledge. Maybe you can't organize the bookshelf a little? There are more than 50% of the books on the bookshelf. Although the authors are different, the contents are similar. Sometimes Yi Lin even reads several textbooks of the same type, and even shows exactly the same sentences.

After Yi Lin exploded A Deng several times, A Deng was also scared and directly gave Yi Lin the authority to the 54th floor library and became the manager.

It also calls it: True geniuses rely on self-study.

"Huh? This one seems interesting."

"Detailed explanation of the layout of crystal patterns, nodes and cores in super-large composite circuits".

There are three libraries in this large engineering tower.

A Deng treats him well. The collection of books in the 54th floor library is the highest-level library. Ordinary students cannot enter, and they are not even open to "exchange students".

In the huge library, there were no other students except Yi Lin, and there was so quiet that only the sound of Yi Lin flipping books was left.

"This game is so interesting. I'm really curious whether this knowledge was fabricated out of thin air. The principles in it are well explained. Once I really learn it, I can't help but be addicted to it and have no intention of leveling up. In this way, I'm really an incompetent 'elite player'."

For a whole month, in addition to finding A Deng to complete the corresponding assessment and a reasonable schedule, Yi Lin spent most of his time in the library.

Perhaps even A Deng could not imagine how many books Yi Lin read and how much knowledge about "crystal pattern science" has been mastered in this month.

Even after taking the time, Yi Lin browsed "The Mechanical Structure of a Floating Boat".

Unfortunately, Yi Lin was not very interested and did not put too much thought into this.

"The crystal in this game world is equivalent to a pure 'energy source', but crystal pattern science can use this 'energy source' in a specific way to play a specific role. No matter the thickness of the pattern, the distribution of nodes, and the number of cores, it determines how much this 'energy source' can be used."

"And this energy source is a one-time non-renewable resource. No wonder they are so anxious after the so-called "crystal mine" is exhausted. Everything in this game world cannot be separated from "crystal". Once the crystal is lost, many facilities in this world cannot operate. Oh, the game setting should be like this."

But, is that really the case?

Yi Lin closed her eyes.

Over the past month, Yi Lin has asked herself countless times, the same question.

Is this really just a pure game world?

Whether it is the interaction with NPC or the complex, mysterious but outrageously complete crystal pattern system, it is difficult for Yi Lin to believe that he is currently in a simple game world.

It is hard for him to imagine who can have this ability to create a huge technological system.

Yi Lin even had a feeling that this strange technology could be used even if it was put into reality.

Of course, the premise is that there is an energy source such as "crystal" in the real world.

"But the essence of crystal is just a kind of 'high purity energy'. Can other energy be replaced by it?"

Yi Lin was flipping through the book and was distracted, and many thoughts flashed through her mind.

One hour later.

Yi Lin remembered another book.

He silently closed the "Detailed Explanation of the Crystal Patterns, Nodes, and Core Arrangements in Super Large Compound Circuits". While there was still time, he continued to stand up and go back and forth in the neat bookshelf to see if he could find interesting books.

"Hmm? Is this?"

Yi Lin's eyes swept across the corner of the bookshelf.

There was an ancient book with no text on the cover. This ancient book was made of the skin of a certain monster. It looked very ancient, and there were many cracks on the skin of the monster. When you opened the title page, the inner page had turned yellow. Obviously, this book had experienced many vicissitudes.

"Is it necessary to spend so much effort on such details just a game?"

Yi Lin smiled softly and looked at the three words on the title page.

——"World History".

"oh?"

Irin was curious, patted the dust inside, and then, with the soft crystal light, she simply sat on the ground to read.

I don't know how long it took.

Yi Lin sat upright.

The smile on his face gradually calmed down and he changed into a solemn look.

"bite!"

It was at this moment.
