“It’s expensive…”

?!

Suddenly, when he heard the soft music, the little aunt opened her mouth wide and was surprised to be able to stuff a pear. He wanted to spit out something, but then he swallowed it back.

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

Within a few seconds, he hurried forward and carefully checked. Each screw was twisted very refreshingly, and there were no extra parts.

“How did it do it?”

After cooling the radio, he turned on again and repeated it several times in a row. Each playback was perfect, and the smile on his face was hard to hide.

"You can fix the radio?"

The appreciation has been made, and the flawed antiques have become perfect antiques. The original doubts have long been thrown out of the sky and just pretend that they have never happened.

Zhang Yuan thought about it and answered honestly: "I haven't learned it, but I have read relevant knowledge on the Internet before... I think about it carefully and I can find the reason."

He repeated the whole logic of his thinking.

"...So I guessed that the former owner of this radio might have removed the vacuum tubes while cleaning the dust. Then he installed them in the wrong order, so he had such a problem."

My uncle didn't understand it when he heard it, but he felt it made sense.

In other words, my nephew thought about it for a while, then he started to fix it.

Thinking about it for a while...

It sounds very simple, but in fact, it is not an easy thing.

He suppressed his desire to brag in front of his friends and said with a smile: "Just like this move you show now, opening an antique repair shop, making hundreds of thousands a year is no problem!"

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

"What I said is true!"

In fact, what is important is not the level of cultivating things, but the ability to see the essence through phenomena.

The specific principles are very simple to explain, but how many of them can be really thought of?

"So, Xiaoqing, you still have to study hard. If you don't even understand the principles and repair them randomly, it will not be repaired well."

Ye Qingqing, who was watching while watching, blinked and found that she was educated again.

So annoying! He actually repaired it.

Other people's children are really an unbeatable enemy of life!

What are the "vacuum electronic tubes" and "radio frequency circuits" sound like a very knowledgeable and convincing feeling, which makes her feel a deep sense of powerlessness and doesn't even have the chance to interrupt.

even……

A faint sense of worship was created.

Think about what is in your head: 50% of your energy is spent on longing for "love", such as school grass, class grass, and big star Cai Xukun's appearance problem; 30% of your energy is spent thinking about what to wear, what to eat today, and whether you will get acne; the remaining 20% ​​of your energy is divided up by other things, including novels, TV series and... learning.

It would be strange if you can learn good things.

Her head was insidious.

The little uncle kept thanking Zhang Yuan and even had to pay the repair fee, which made him feel embarrassed.

"If you are outside, the repair fee is at least two or three thousand yuan..."

"My uncle, how can I charge you money? Money is useless to me." Zhang Yuan was embarrassed.

Ye Qingqing was just laughing secretly.

She suddenly felt that it seemed that having a smart cousin was pretty good.

At least, you can move out and brag in front of your best friend.

The word "官" in "coon" seems to be able to be removed, just say it is your own brother. Anyway, it's nothing to grow up together. The identity of an astronaut is very valuable...

Thinking of the envious and jealous expressions of hatred by the best friends, Ye Qingqing felt more and more that this thing was cool, really cool!

...

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

Before leaving, my sister-in-law forced him to give him a big red envelope, a full 10,000 federal coins!

In fact, Zhang Yuan is not short of money, and money is of no use to him.

However, since it was the intention of his relatives, he still accepted it. The main reason was that he could not refuse and stuffed the red envelopes around, and he really couldn't resist those elders.

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

"99 points... I'm afraid I'm proud of the remaining one!"

An antique radio that produces noise, the kind you have never seen before, would only be confused if it were placed in the past.

This strong sense of satisfaction is like a rich coffee, which makes people feel endless aftertaste.

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

In the past, even if he had such knowledge in his mind, he might not be able to deduce relevant conclusions, nor did he have the ability to learn from one example or another.

Having knowledge and applying knowledge are two completely different difficulties.

"But it's different now...ha!"

This magical power made Zhang Yuan very happy.

Not only that, he seemed to have a child-like curiosity again and had a strong desire to explore everything.

Humans have the strongest curiosity and imagination in childhood, but as they grow older and their education increases, their curiosity and imagination continue to decrease. This is the price of growth.

Children can play with some boring toys for a long time and have an endless desire to explore the world. But when they grow up, they can't do it anymore. They will get tired of doing something, hate learning, and hate using their brains.

In other words, he has a innocent heart again!

To put it bluntly... I just want to learn, whether it is mathematics or physics, exploring this world can bring an angry sense of accomplishment.

Things that looked very boring are now becoming very interesting.

"I really want to go back and keep studying... Am I a perverted science giant?"

Zhang Yuan was a little curious about what the strange potion was, which could actually change a person's thinking level and interests.

"Is there really such black technology on Earth?"

"Smart medicine?"

After checking the phone casually, Zhang Yuan was shocked, and there was really something!

???

Some neurostimulant Western medicines, including Ritalin, modafinil, etc., are called "smart medicines". Many college entrance examination students, college students and business managers take drugs similar to stimulants to enhance temporary memory and make their thinking more flexible.

However, this type of drug belongs to the stimulant type, which is addictive and can cause dependence on long-term use. It may even have side effects such as insomnia.

Zhang Yuan calmed down: "I'm really a ghost... These drugs are just stimulants, and they have to be taken every day, and it's impossible to have such a strong effect."

"Dad can't give me something that has side effects,"
Chapter completed!
