"I found that those who read the book did not seem to find anything wrong with what it was written, but rather admired the ideas and purposes of the book. Because it is very clear from these pages of the book that this person not only made great emphasis on the book, but also often marked notes in the margins next to some paragraphs. This shows that this person is not only very sure that the knowledge of this book is correct and helpful, but that he has 'benefited' a lot from this book, that is, he has already mastered a lot of the knowledge recorded in this book. ”

But here's the problem -- the last paragraph of where this seal exists, says that there's the quickest, most intuitive, and most authentic way to understand something. And he cites a series of seemingly convincing but flawed examples to prove this point. In other words, people who read this book will also fully believe in this idea 100%. The younger brother's expression began to become solemn, as if he thought of something bad, "You know what? The kind of method written in the book is - dissection. Yes, it's the kind of anatomy that is cut open. Well, here's what it says: 'Break down everything you want to know piece by piece, break it down to the smallest parts, and observe it, and you will know everything you want to know.' ’”

He raised his eyes to look at me, and his eyes were full of pleas: "But the point is, you look at the handwriting in the notes of this book, and the strand of hair that accidentally fell into it, is it particularly familiar?" I really doubt that the person who read this book is our 'mother'. After saying that, a trace of uneasiness and panic flashed in the younger brother's eyes.

"'Daddy' is in danger now!!" My mind raced, and I immediately screamed in fright.

"Shhhh......hhh We can't let 'Mom' know that we found out that she read this book, and now, otherwise how can we save 'Daddy'? …… Come to think of it, we are the only ones who can save him now. With that, he lowered his head again with a heavy face.

I nodded, indicating that I wouldn't react so violently anymore, and my brother slowly let go of his hand.

"Then first we have to find the two of them as soon as possible, the later it is, the more dangerous it becomes." I grabbed my brother's hand and said in an airy voice.

The younger brother nodded in agreement. We continued to search this floor together, and found that "Mom and Dad" were indeed not there, and it was estimated that they had already left this floor to go somewhere else, so we decided to go up to the fourth floor to have a look.

The reading room on the fourth floor is very different from the second floor. Although the size and specifications of the room are still the same, because it is a special layer for electronic telecommunications, some enlarged circuit board schematics and PCB diagrams are specially painted on the wall as decorations, and the bookshelves have been changed from wooden to stainless steel plates, and the overall layout is placed according to the direction of a circuit diagram, which is quite a bit of a maze.

"You start with the rest area at the edge of each row of shelves, I'm mainly in charge of the bookshelves, okay?" I patted my brother on the shoulder and whispered in his ear.

He nodded: "I still have to yell if I remember something." ”

I nodded my head and said I understood, and we went our separate ways again.

I first slipped into the rows of bookshelves. The horizontal row of bookshelves followed by the diagonal row of bookshelves really looks like a circuit diagram.

Speaking of which, everything on this floor should have something to do with my major, right? If I hadn't had something important to do, I would have really wanted to pick one or two books and sit down and have a good taste and study, after all, I have admired this place for a long time, and it is said that even the first and second volumes of "Transistor Circuit Design - Experimental Analysis of Amplification Circuit Technology", "OP Amplification Circuit Design - From the Basics of Reproducible Design to Practical Application", "Design and Application of Oscillation Circuits - Experimental Analysis of RC Oscillation Circuits to Digital Frequency Synthesizers", "Digital System Design" From the basics of digital technology to the analysis of ASIC design, "ASIC design of digital logic circuits" are all here, which is simply a paradise for our science and engineering students.

Unfortunately, it can't, finding "mom and dad" is the most important thing. I swayed through the rows of bookshelves, but I never saw a trace of anyone else's presence.

Isn't it on this floor either? …… I sighed a little disappointed, and was about to go back the way I came to look for my brother when I suddenly saw something move in front of me. A book was siphoned out of front of me by the person opposite.

Hey? Someone on the other side?! I hurriedly ran to the opposite aisle as fast as I could, only to find that a whole row of books was stacked on the ground, and the corresponding bookshelf was empty for a whole row, revealing the books on the bookshelf behind me. There was no one in the aisle.

I looked around, but I didn't find anything: it was quite far from the next exit, and the nearest exit was blocked by me, so it stands to reason that the other party should not have had time to escape in such a short time before I ran over, right? How could it have made me look at the back a little, but there was nothing here, like magic...... How the hell did the other side do it?!

And it wasn't just the whole row of books that I found abruptly placed outside, as soon as I came over, but also a small note in the middle of the book, which said, "Go back quickly." ”

What does it mean to go back quickly? Who the hell wrote this? I really can't see it from the handwriting.,It's like a crooked elementary school student who has just learned to write.,I have to say that there's no deterrent at all...... Probably the person who wrote it didn't want us to guess the identity, so he wrote it with his left hand.

But why do you tell us to "hurry back"? What's going on here? I began to worry vaguely again. If someone from the "Mom and Dad" left this message, it is highly likely that something is really going on here in terms of their usual personality qualities - "Mom and Dad" would never joke with me about this.

Speaking of the row of books that were pulled out...... Is it to expose the row of books in the back so that I can pull out the books on my side of the bookshelf to get my attention?

It seems that this is not the only way, but this row of books is clearly not the books that should be on this floor, but seems to be books related to biological simulation.

The biological simulation should be on the tenth floor, why was it specially moved here? Could it be that the other party had expected that we would come here to search for something, so they had already moved the books and ambushed us here? As for the book that chose the biological simulation layer, is it a reminder of what we have there?

But it's clear that the small note on it reads, "Go back quickly...... Looks so contradictory, doesn't it?
