A dilapidated magazine brought Lin Hong into another magical world, and he realized that there were so many invisible radio signals in the seemingly empty space. For the first time, I fundamentally understood the principle of radio sound.

According to the magazine, the "ore radio" is very magical, it can listen to the radio station in the air without a power supply, and the components required are very simple, so it is completely suitable for beginners.

As a result, Lin Hong made the production of an "ore radio" his latest goal.

Originally, Lin Hong only needed to make it directly according to the instructions of the magazine, and he didn't need to fully understand the principle at all. However, this is not what Lin Hong wants, his powerful curiosity** will never allow himself to do it so simply and finish it, he must fully understand the role of each of the originals.

So, he started his reading plan by following the list of books recommended by the author in the book.

That reading list included six reference books, and Lin Hong remembered very well that these six reference books were all collected on Lao Xutou's bookshelf.

During the day, Lin Hong sat upright in his seat, his eyes looking at the teacher on the podium, but his mind was recalling the content of "Concise Radio Principles".

In the dark night, Lin Hong led Ah Huang, a man and a dog quietly hid under the tree, and saw the dawn by the electric light of the car and wood factory.

Five days later, Lin Hong had finished reading the book, and except for some knowledge he hadn't learned yet, he basically understood the above content.

It was Saturday again, Lin Hong came to Lao Xutou's yard again, and he was surprised to see that there was another inch-headed old man in a big white coat in the yard today.

As soon as Lin Hong walked to the gate of the courtyard, the old man had already noticed it, he glanced at him from a distance, but Lin Hong felt that his scalp was numb for a while, as if he was suddenly stared at by some fierce beast, and even felt a little difficult to breathe.

"General!"

Lao Xu Tou shouted, grabbed a chess piece in his right hand and slapped it on the chessboard he had drawn with ink lines on the small table.

The inch-headed old man's face changed, and he hurriedly moved his eyes to the chessboard, and found that he didn't know that the little red horse that Lao Xu Tou had jumped over the Chuhan River boundary had actually formed a "hindsight" nirvana.

"Nope! Not counts! ”

The inch-headed old man's voice was surprisingly loud, high-pitched and loud, and he saw him pick up the little red horse of the old Xu head and retreat to the same place, and wanted to retreat the move he had made before.

Old Xu Tou's happy face suddenly fell, and he hurriedly grabbed the wrist of the inch-headed old man:

"Old grandson, we have agreed in advance, don't cheat!"

"I was just distracted." The inch-headed old man retorted, "It's all to blame on this kid, if he hadn't suddenly appeared, I wouldn't have made such a stinky move, right?" Can't I see it as an afterthought? ”

After speaking, the inch-headed old man looked fierce and looked at Lin Hong with wide eyes: "Boy, what are you doing here?" ”

"I... I ......"

Lin Hong was so frightened by his momentum that he took a half step back.

"Okay, old grandson, put away your set, I don't know you yet? Don't freak out kids. ”

Old Xu Tou showed a helpless look on his face, obviously he had already understood the tricks of this old grandson.

"Lin Hong, don't be afraid. This is Grandpa Sun from the next village, and he's playing around with you. Old Xu Tou turned around and said to Lin Hong.

"Grandpa Sun, hello, my name is Lin Hong." Lin Hong hurriedly said hello.

"Little one, you're very polite." Old Sun Tou nodded with satisfaction, "Although people are clever, their personalities are a little too girly." The little guy, a manly man, stands up to the sky, walks up, should raise his head and chest, steel! Like you just ......."

"Alright, alright, you'll talk a lot." Lao Xu Tou hurriedly interrupted him, Lao Sun Tou didn't know Lin Hong's situation, and if he didn't stop it, the outspoken old Sun Tou would definitely hurt Lin Hong.

Then, Lao Xu asked Lin Hong: "Lin Hong, do you have something to do today?" ”

"Grandpa Xu, I've finished reading this book, come and return it." Lin Hong raised the book in his hand, and then said, "In addition, I want to borrow a book to read back." ”

Finished reading it so soon?

Old Xu Tou was surprised, but he didn't say much, but said directly:

"Well, you just put the book back on the shelf, what book do you want to borrow, go there and find it yourself, the door of the room is not locked."

After speaking, he did it again, beckoned Lao Sun Tou to continue playing chess, and finally agreed to the other party's repentance under the opponent's tricks.

Lin Hong saw that Lao Xu Tou didn't have time to greet him, so he limped towards Lao Xu Tou's house.

The old grandson looked at Lin Hong's back, and then he understood why the old Xu Tou interrupted his words just now.

"This kid has a bad leg?"

Lao Xu nodded and said: "He is a kid from Lin Changming's family, he had a brain fall when he was a child, and as a result, he left sequelae, which should have injured the cerebellum and affected his balance function." ”

"Oh~" Lao Sun Tou's face was abrupt, "I remembered, I heard that there was such a child in your village before, who broke his skull when he was a child, and turned out to be a fool...... That's him? ”

Lao Xu Tou shook his head: "He's just a little inconvenient in his legs and feet, and a fool won't be ......."

Speaking of this, Lao Xu Tou remembered the contact with Lin Hong in the past few days, and said casually: "Maybe he is the smartest one among his peers." ”

Lin Hong came to Lao Xu Tou's room, and this time he had a different feeling in his heart, because this time Lao Xu Tou did not follow him, and his heart was completely free of the previous sense of restraint, and he felt very comfortable.

He first walked briskly to the bookshelf, opened the black bra, and then went back to the books on the shelves. This time it was much slower than the last time, and he memorized the names of each book in his heart, just the titles, because if he wanted to read them one by one, he would definitely not have time.

However, the titles of the books were also very emotional for him, because they often contained a lot of information, which greatly increased his horizons.

For example, through the book "How to Suppress the Interference of Electrical Equipment to Radio", he can know that electrical equipment has a negative effect on radio, and there have been experts and scholars who have done research on this topic and found out how to deal with it.

Lin Hong's memory ability is very strong, last time he just walked through it in a hurry, it was as if a virtual bookshelf appeared in his mind, and if he wanted to know which book was in which position on the shelf, he just had to think about it a little. It's just that he didn't finish reading it last time due to time constraints.

This time, it only took about seven or eight minutes for him to complete the bookshelf in his mind.

Then, he took out a book called "Fundamentals of Electricians", which was a book mentioned by the author in the preface to his previous book "Concise Principles of Radio", and the other party said that in order to fully understand the contents of that book, it was necessary to master the basic knowledge of "Fundamentals of Electricians".

Lin Hong opened "Electrician Basics" and flipped it a little, and was pleased to find that this book is really the foundation of the foundation, which is specially prepared for those who do not have any knowledge of electronics, and some common basic concepts and formulas are explained in it.

Lin Hong closed the book and was about to continue reading other books when a "rustling" sound suddenly came from the room, which startled him.

When he heard the sound, it turned out to be coming from the "radio station" of Lao Xu Tou.

Before he could get to the front of the station, the sound came from the speakers again, and this time it was no longer noise, but very clear speech.

"Rustle... cqcq, here is by4bu calling cq and waiting for answer......"
