"It's expensive...... ......"

？！

Suddenly, hearing this soft music, the sister-in-law's mouth opened wide and he was surprised to be able to stuff a pear. He wanted to spit out some words, but he quickly swallowed them back.

Unexpectedly, Zhang Yuan really repaired the radio, and in a very simple way!

He was stunned for a few seconds, then hurriedly stepped forward and carefully checked, every screw was screwed very cleanly, and there were no extra parts.

"How?"

After cooling the radio, he turned it on again and repeated it several times, each time playing perfectly, and the smile on his face could not be hidden.

"Will you fix the radio?"

It has appreciated, and the flawed antique has become a perfect antique. The original doubts have long been thrown out of the clouds, as if they never happened.

Zhang Yuan thought about it and replied honestly: "I haven't learned it, but I've seen relevant knowledge on the Internet before...... If you think about it, you can find out why. ”

He repeated the whole logic of his thoughts.

“…… So I guess the previous owner of this radio may have removed the vacuum tubes during the cleaning process. Then put it on in the wrong order, so there was such a problem. ”

The sister-in-law didn't seem to understand when he heard it, and he felt quite reasonable.

In other words, his nephew thought about it for a while, and then he did it, and he really repaired it.

I thought about it for a while......

It sounds simple, but in reality, it's not that simple.

He suppressed his desire to brag in front of his friends, and said with a smile: "With the hand you are showing now, it is not a problem to open an antique repair shop and earn hundreds of thousands of dollars a year!" ”

"How can it...... Actually, I don't understand at all. ”

"What I said is true!"

Actually, what is important is not the level of cultivation, but the ability to see the essence through phenomena.

The specific principle is very simple to explain, but how many can really be thought of?

"So, Xiaoqing, you still have to study hard. If you don't even understand the principle and repair it indiscriminately, you can't fix it. ”

Ye Qingqing, who was watching from the side, blinked her eyes and found that she had been educated to her head again.

It's infuriating! It was repaired by him.

Other people's children are really invincible enemies for life!

What "vacuum tubes" and "radio frequency lines" sounded like they brought a very knowledgeable and convincing feeling, which made her feel a deep sense of powerlessness, and she didn't even have a chance to interject.

Even......

A faint sense of adoration was generated.

Think about what you have in your head: 50% of your energy is spent longing for "love", such as school grass, class grass, and the appearance of big star Cai Xukun; 30% of the energy is used to think about what to wear and eat today, and whether you will get acne; The remaining 20% of the energy is divided between other things, including novels, TV series, and ...... Learn.

It's weird to learn good things.

Her head froze.

The sister-in-law was still thanking Zhang Yuan vigorously, and even had to pay for the repairs, which made him embarrassed.

"If it's outside, the repair cost of two or three thousand is at least ......"

"Brother-in-law, how can I take your money...... Money doesn't do much to me. Zhang Yuan was embarrassed.

Ye Qingqing just snickered on the side.

She suddenly felt that it was nice to have a smart cousin.

At the very least, you can move out and brag in front of your girlfriends.

It seems that the word "table" of "cousin" can also be removed, and it would be good to say that it was his brother, anyway, growing up together, it's nothing. The identity of an astronaut is very valuable......

Thinking of the envy, jealousy and hatred of her girlfriends, Ye Qingqing felt more and more that this thing was very cool, really cool!

……

When I walked out of my sister-in-law's house, it was already three o'clock in the afternoon.

Before parting, my sister-in-law forcibly stuffed him with a big red envelope, which was 10,000 federal coins!

In fact, Zhang Yuan is not short of money, and money is of little use to him.

However, since it was a piece of his relative's heart, he still accepted it. The main thing is that he can't get rid of it, and he stuffs the red envelopes back and forth, and he really can't resist those elders.

Walking on the bustling pedestrian street, Zhang Yuan was recalling his performance just now.

"99 points...... I'm afraid of my own pride! ”

An antique radio that makes noise, the kind that I have never seen before, if I put it in the past, I would only be confused.

This strong sense of satisfaction, like strong coffee, is endlessly evocative.

There is no doubt that his reasoning ability and thinking ability have greatly improved!

In the past, even if he had such knowledge in his head, he might not be able to deduce relevant conclusions, and he did not have the ability to draw inferences.

Possessing knowledge, and applying knowledge, are two very different kinds of difficulty.

"But it's different now...... Ha! ”

This magical power made Zhang Yuan overjoyed.

Not only that, but he seems to have regained his childlike curiosity and a strong desire to explore everything.

Humans are most curious and imaginative in childhood, but as they grow older and more educated, they diminish. This is the price to pay for growth.

Children can play with boring toys for a long time and have an endless desire to explore the world. But when I grow up, I can't do it anymore, I get tired of doing one thing, I hate studying, I hate using my brain.

In other words, he has regained the heart of a child!

Plainly...... I just want to learn, whether it's math or physics, and exploring the world can bring a very angry sense of accomplishment.

What used to look very boring is now very interesting.

"I really want to go back and study all the time...... Am I already a giant of perverted science? ”

Zhang Yuan was a little curious, what was the ingredient of that strange potion, and it could actually change a person's thinking level and hobbies.

"On Earth...... Is there really such a black technology? ”

"Smart drugs?"

After checking his mobile phone, Zhang Yuan was shocked, there really is!

？？？

Some neurosticitant drugs, including Ritalin and Modafinil, are known as "smart drugs". Many gaokao students, college students, and business executives take drugs similar to stimulants to enhance temporary memory and make thinking more flexible.

But this class of drugs belongs to the stimulant type, which has a certain degree of addiction, and long-term use will cause dependence. There may even be side effects such as insomnia.

Zhang Yuan sank down: "It's really a hell...... These drugs are just stimulants, they have to be taken every day, and they can't have such a strong effect. ”

"There's no way Daddy can give me anything that has side effects."

So, what exactly is it?
