country made

Ji Yu was a little confused, this metal detector seemed to him to be extremely crude, both in terms of appearance and technology.However, he was kidnapped!

blatantly.

Plato Leader Xu carried him into the car just like that, and his grandfather let him go without saying a word. Platoon Leader Xu also carefully put the metal detector on the back seat.Ji Yu naturally saw that he attached great importance to this metal detector, so he couldn't help but wonder.

"Uncle, what's wrong?"

He is sure that he has completely avoided military technology, and with the accessories he can collect, even if he wants to use military technology, he won't be able to use it!

Platoon Leader Xu glanced at him and asked, "Little classmate, where is the uncle who taught you how to make a metal detector?"

Ji Yu tilted his head: "I don't know!"

Crunch-! !

Platoon Leader Xu stopped the car and asked Ji Yu, "What's the matter?"

Ji Yu looked confused: "Uncle used to teach me on the farm, but then uncle disappeared and went home. I don't know where his home is!"

Platoon Leader Xu restarted the car: "Okay, let's go to the farm first and show the way."

Ji Yu obediently showed the way, feeling uneasy in his heart, but he blinked his big eyes and asked cutely: "Uncle Liberation Army, why are you looking for uncle?"

Platoon Leader Xu didn't intend to explain to a child, but he might have to rely on the child to find that "uncle", so he said patiently: "We are fighting with Vietnam recently, in the Laoshan area, Vietnam A lot of landmines have been set up, and many comrades in arms have been..." His voice was a little hoarse, he glanced at the rearview mirror, and said, "The metal detector you took out may be useful to us. I want to find the person who made this thing."

Ji Yu was stunned, and even forgot to be cute: "Aren't there any in the army?"

"Yes, but it's not that flexible, and it's useless underwater, otherwise it wouldn't have disabled so many soldiers."

Ji Yu: "Ah...!!"

Ji Yu was born in 00. In the era of his birth, the deminers were so good that he couldn't estimate the deminers of this era. He thought that what he made was simple enough, but he didn't expect that the mines of this era were even simpler.

But think about it, before he was reborn, the landmines planted on the Sino-Vietnamese border hadn’t been cleaned up, which shows how many landmines there were at that time and how important a good deminer is. !

Platoon Leader Xu drove extremely fast. When the military pickup truck entered the farm, Ji Yu was still in a daze. Did he get out the non-existent deminer ahead of time?The farm manager saw that it was a military vehicle, and immediately ran over to receive it.Platoon Leader Xu gave him a military salute, without saying a word, he lifted Ji Rafter off from the other side, took out the metal detector, and asked the farm director: "Is this kid from this farm?"

The farm manager naturally knew Ji Zhuan and nodded: "This is the son of our employee Ji Jianguo. Ji Jianguo, your son is here!"

When he yelled, not only Ji Jianguo, but also other people on the farm came out, and the grandpas who were resting in the house also came out.

"Yuanyuan?" Seeing his son standing listlessly beside an officer, he hurried over to pick him up: "Why, what happened? Comrade, what's wrong with my son?"

Platoon Leader Xu didn't understand either, and finally he could only say, "Sorry, maybe I was driving too fast."

Seeing that his driving style didn't look like Ji Yu's causing trouble, Zeng Yihua stepped forward and asked, "Comrade PLA, what's the matter with you here?"

As soon as Platoon Leader Xu saw this group of old people, he knew who they were. These were old comrades who were persecuted back then. Now that the country has been rehabilitated, when they return to their original posts, many of them may have higher positions than him.In addition, the uncle mentioned by Ji Yu may be from here, so Platoon Leader Xu respectfully said to them: "That's right, I want to find the person who made this metal detector? I wonder if you have any information about this comrade? "

"Metal detector, what's that?"

After some explanations, everyone understood the principle of the metal detector, and naturally understood its function.They read the newspapers every day, so they naturally know that the self-defense counterattack against Vietnam on the border is now in full swing, and the reports from the rear are only full of victories.

Although metal detectors cannot play a decisive role, they can certainly reduce the danger of soldiers in mine warfare. The person who designed this metal detector has made great contributions.

They also wanted to help find this person, but when they were dispatched, no one dared to talk about their own affairs. When they could talk casually, many people returned to the city. When they asked whose family was where and how many people were there, they said yes If you ask who is good at what and what they have studied, they will not know.After all, it was taboo at that time.

So I still had to ask Ji Yu: "Yuanyuan, do you really not remember who that uncle is?" Ji Jianguo coaxed his son: "For example, does he have a beard? Does he wear glasses? What's his last name?"

Ji Yu also understood the situation at this time. Since he was helping the border soldiers, he certainly did not regret taking out the metal detector in advance.Soldiers are fighting bloody battles on the front lines, and he can at least help a little in the safe rear.However, he couldn't come up with an uncle. If he could, he didn't want to disappoint Platoon Leader Xu at all.

"I don't remember..." Seeing that his son was about to cry when being questioned, Ji Jianguo couldn't bear to force him any longer, and apologized to Platoon Leader Xu: "Sorry, comrade, my son has been sick before, and his brain is not good. I'm afraid it's true. Can't remember."

Platoon Leader Xu nodded helplessly, and then asked Ji Yu: "Little friend, can you give me this metal detector? I need it very much."

Ji Yu nodded naturally, and said again: "I... I can draw drawings. Uncle taught me before. Let me draw for uncle!"

Xu Paichang was overjoyed, it is of course good to have drawings, so as not to dismantle this thing.After taking the drawings drawn by Ji Yu, Platoon Leader Xu took a deep look at him and saluted him: "On behalf of the frontline soldiers, I would like to thank Comrade Ji Yu and that unknown comrade for their help."

The author has something to say:

After writing so much, I came back to explain this chapter specially. I am also very tired ╮(╯▽╰)╭

For readers with poor comprehension:

The protagonist makes up a fictional uncle to express: I have learned the knowledge of electrical engineering and electronics, so it will not be surprising to study it by myself in the future.

But someone thought the main character was saying: I only learned how to make a metal detector.

Drawing drawings:

Because I found that more than one person thought that "the protagonist's ability to draw pictures will reveal his identity as a scientist", and expressed Σ(っ°Д°;)っ, but also had to come out to popularize science.

Drawing circuit diagrams is the basis of all science and engineering. It is the same as learning English and learning ABC first. If you don’t know how to read or draw pictures, you can’t even be an electrician, okay?

In the end, I said that I am so tired... You don’t need to know science and engineering, and you are not interested in Baidu, but don’t use your imagination to question me ε(┬┬_┬┬)3 I am really suffering
