  An old worn-out magazine led Lin Hong into another magical world, and he just discovered that in the seemingly empty space, there were so many invisible wireless signals. For the first time, he fundamentally understood the sound-emitting principle of radios.

  According to the magazine, the "stone radio" is very magical. It can receive wireless radio stations in the air without using a power source, and the components required are also very simple, making it suitable for beginners to make.

  Then, Lin Hong will make a "mineral radio" as his latest goal.

  Originally, Lin Hong only needed to follow the magazines instructions directly to make it, and he didnt need to understand the underlying principles at all. However, this was not what Lin Hong wanted. His strong desire for knowledge absolutely did not allow himself to simply do it well and be done with it. He had to fully understand the role of each component involved.

  He then started his plan according to the book list recommended by the author in the book.

  That list includes six reference books, Lin Hong remembers very clearly that the six reference books are all collected on Old Xus 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 contents of "Principles of Radio".

  Black night, Lin Hongze led A Huang, one person and one dog quietly hiding under that tree, borrowing the car wood factorys electric light to see until dawn.

  Five days later, Lin Hong had already finished reading the book and basically understood all the content except for some knowledge he hadnt learned yet.

  Its Saturday again, Lin Hong came to Old Xus yard once more. He was surprised to see that there was another old man with a shaved head wearing a white coat in the yard today.

  Lin Hong had just walked to the gate of the courtyard when the old man sensed his presence. He looked at Lin Hong from afar, but Lin Hong felt a chill run down his spine as if he was being stared at by a fierce beast, and even his breathing seemed labored.

  "General!"

  Old Xu shouted loudly, his right hand grasping a chess piece and slapping it heavily onto the chessboard he had drawn with ink on the small table.

  The old mans face changed, and he hastily shifted his gaze to the chessboard, only to discover that Old Xus little red horse had somehow jumped over the Chu-Han border and formed a "cannon behind the horse" checkmate.

  "Doesnt count! Doesnt count!"

  The old mans voice was surprisingly loud and clear, only to see him pick up Old Xus little red horse and retreat to his original position, wanting to take back the move he had just made.

  Lao Xutous delighted face suddenly fell, and he hastily grabbed the old man with a shaved head by the wrist:

  "Old Sun, we had an agreement beforehand, no cheating allowed!"

  "I was just distracted for a moment." The old man with the inch-long hair retorted, "Its all because of this kid. If he hadnt appeared suddenly, I wouldnt have made such a terrible move next. Dont you think I can see through a horse after it has passed?"

  The old man with a buzz cut had a fierce look on his face, staring at Lin Hong with wide eyes: "Youngster, what are you doing here for no reason?"

  "I... I..."

  Lin Hong was intimidated by his aura and took a step back.

  "Alright, old Sun, put away those tricks, Im still not sure whats going on? Dont scare the kids."

  Old Xus face showed a helpless expression, obviously having been taught by Old Suns tricks before.

  "Lin Hong, dont be afraid. This is Old Sun from the neighboring village, hes just joking around." Old Xu said as he turned his head back to Lin Hong.

  "Grandpa Sun, okay, Im Lin Hong." Lin Hong hastily greeted him.

  "Little guy, quite polite!" Old Sun nodded in satisfaction, "Although clever, the personality is a bit too feminine. Little guy, as a man, one should be upright and walk with head held high, chest out! Like just now..."

  "Alright, alright, thats enough." Old Xu hastily interrupted him. Old Sun didnt know about Lin Hongs situation and if he wasnt stopped, his straightforward and outspoken nature would definitely hurt Lin Hong.

  Then Old Xu asked Lin Hong: "Lin Hong, what brings you here today?"

  "Uncle Xue, Ive finished reading this book and Im returning it. Also, Id like to borrow another book to take home."

  Have you finished reading it so quickly?

  Old Xu was surprised in his heart, but he didnt say much and directly said:

  "Uh-huh, just put that book back on the shelf. If you want to borrow a book, go find it yourself. The door isnt locked."

  After finishing speaking, he started again, inviting Old Sun to continue playing chess, and eventually agreed to the opponents request for a rematch under the opponents tantrums.

  Lin Hong saw that Old Xu was too busy to greet him, so he hobbled towards Old Xus house.

  Lao Sun looked at Lin Hongs departing back and only then understood why Lao Xu had interrupted him just now.

  "Is this child clumsy?"

  Old Xu nodded and said, "He is the young son of Lin Changmings family. When he was a child, he suffered a head injury, which left him with sequelae. He must have hurt his cerebellum, affecting his balance function."

  "Oh?" Old Suns face was suddenly enlightened, "I remember now, Ive heard before that there was a child in our village who fell and hurt his head when he was young, and as a result became an idiot... is it him?"

  Old Xu shook his head: "Hes just a bit inconvenient with his legs and feet, but hes not stupid..."

  Old Xu suddenly thought of his interactions with Lin Hong over the past few days and casually said, "He might be the smartest among people of the same age."

  Lin Hong came to Old Xus room, this time with a different feeling in his heart, because this time Old Xu didnt follow him, and he no longer had the previous sense of restraint, feeling very comfortable.

  He quickly walked to the front of the bookshelf, pulled open the black cloth, and then started browsing through the books on the bookshelf again. This time was much slower than before, he deeply remembered the name of each book in his heart, just remembering the book names, because if he had to look at them one by one, there would definitely not be enough time.

  However, it was precisely those extremely professional book titles that made him very excited, because these book titles often included a lot of information, greatly broadening his horizons.

  For example, through the book "How to Inhibit Electromagnetic Interference of Electrical Equipment on Wireless", he can know that electrical equipment has a negative impact on wireless and experts have done research on this topic and found countermeasures.

  Lin Hongs memory was very strong, last time he just walked through it hastily, in his mind there seemed to be a virtual bookshelf, wanting to know which position on the bookshelf had which book, he only needed to think about it slightly. Its just that last time due to time constraints, he didnt finish looking.

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

  Then, he took out a book called "Electrical Engineering Fundamentals" from among them. This was the book mentioned in the preface of his previous "Principles of Wireless Telegraphy", which said that to fully understand the content of that book, one must first grasp the basic knowledge in "Electrical Engineering Fundamentals".

  Lin Hong opened "Electrical Engineering Fundamentals" and flipped through it briefly, delighted to find that this book was truly fundamental, specifically designed for those with no prior knowledge of electronics. It explained some common basic concepts and formulas.

  Lin Hong closed the book and was about to continue looking at other books when a sudden "rustling" sound came from inside the room, startling him.

  He heard the sound and looked over, it turned out that it was coming from Old Xus "wireless radio station".

  Before he even reached the front of the radio station, the speaker emitted sound once again, and this time it was not noise, but a very clear voice. "Q, this is BY4BU calling CQ and waiting for response..."
