And the progress is very fast. You must know that Qin Huairu used to make first-class workpieces, which were only seven or eight defective products out of ten.

But now Qin Huairu has almost a [-]% yield rate, unless it's because of distraction or accident.

As long as Qin Huairu is serious, he will basically be [-]% successful.

Now Qin Huairu is very grateful to the person who broke Yi Zhonghai's leg. If it weren't for this person, how could Qin Huairu learn the skills of a second-level fitter.

Now Qin Huairu just wants to learn more skills before Yi Zhonghai comes back.

As long as he can learn the third level of fitter, he can become an apprentice, and there is no need for Yi Zhonghai to take him with him.

Yi Zhonghai didn't know that while he was recuperating, not only was his home stolen, but the little widow he had raised was also taken away.

I wonder what Yi Zhonghai will think when he comes back?

However, it is impossible for Yi Zhonghai to know, after all, Yi Zhonghai can't save his life at this time.

Without Yi Zhonghai and Auntia, the quality of life of the deaf old lady has plummeted.

I can only eat from the big pot with everyone else. You must know that in the past, everyone ate from the small stove alone.

Although it's not that good, the corn paste, steamed buns, and pickles are still affordable.

But now, basically what everyone eats, what does the deaf old lady eat?

If you don't go out to eat, no one will care about the deaf old lady.

And He Yuzhu found Gu Zhiqiu:

"Lao Gu, these are all things I made. You can arrange to build the factory!"

Gu Zhiqiu could understand all the previous drawings, but this time, Gu Zhiqiu didn't recognize them at all.

And it's not made of steel, it's basically plastic.

If it weren't for He Yuzhu's previous petrochemical industry.

Plastics are hard to come by these days, but they are still available.

Looking at this thing, Gu Zhiqiu asked:

"Pillar, what is this?"

He Yuzhu said to Gu Zhiqiu:

"This is a mobile phone, can it also be called a mobile phone?"

Gu Zhiqiu asked:

"Mobile phone? You mean a phone, a phone without a line?"

He Yuzhu nodded:

"That's right, it's a phone that doesn't require a cord. You can use it wherever you go!"

Hearing He Yuzhu's words, Gu Zhiqiu was very shocked, and then said:

"Really?"

He Yuzhu said:

"I'm going to lie to you again. I installed a signal tower here. And it also has a decoder.

This is a test product I made. It can make calls within a radius of about [-] kilometers, but after more than [-] kilometers, the call quality is not good.

Signal strength is not enough.

But I installed a signal amplifier on this thing, and there is a signal amplifier between the two signal towers.

This makes up for the lack of signal availability.

You try it first, and then I’ll tell you how to do it! "

After hearing what He Yuzhu said, Gu Zhiqiu took the mobile phone that He Yuzhu handed to him.

Look at this small, lightweight thing and ask:

"This is it?"

He Yuzhu nodded:

"Yes, that's it. You'll know if you try it. I'm here now. You can drive in any direction, as long as you don't go more than thirty kilometers.

Have you seen these numbers? "

Gu Zhiqiu nodded:

"I see!"

He Yuzhu said:

"When the time comes, press the button!"

Gu Zhiqiu was stunned:

"what?"

He Yuzhu said:

"You press 1 on the first keyboard, then press 10 8s on the next one, and then just wait!"

After hearing what He Yuzhu said, Gu Zhiqiu didn't know the reason, but nodded, took the mobile phone given by He Yuzhu, and drove away.

He Yuzhu was thinking, what to do next?

Half an hour passed quickly, and at this time, the mobile phone beside him rang.

He Yuzhu answered the phone and said:

"How's it going, Lao Gu, where are you now?"

Gu Zhiqiu heard He Yuzhu's voice over there and was very shocked. He did not answer He Yuzhu's words:

"Can you really make a call?"

He Yuzhu:

"Nonsense, I can't talk on the phone, why should I spend so much money?"

He Yuzhu's words did not make Gu Zhiqiu angry, but Gu Zhiqiu was very shocked:

"What's the furthest distance this thing has?"

Gu Zhiqiu knew that this thing was much better than his own walkie-talkie.

And it’s a one-to-one call.

He Yuzhu said:

“If we build signal towers as I said, we can make calls all over the country.

What's wrong? "

Gu Zhiqiu was stunned for a moment, and then said:

"Within the whole country?"

He Yuzhu nodded:

"Yes, within the country, if you have the ability to install signal towers abroad.

Then you can make calls all over the world! "

After hearing He Yuzhu's words, Gu Zhiqiu knew that this thing could change the global landscape.

Then ask:

"How much does it cost?"

He Yuzhu thought for a while, and then said:

"The cost is not cheap, five or six hundred, right? What's wrong?"

After hearing what He Yuzhu said, Gu Zhiqiu said:

"Five to six hundred, it's not bad, I can accept it!"

You must know that this thing is too powerful and too convenient for people below to use it, but it is not too convenient among the military and the government.

Gu Zhiqiu said:

"You are waiting for me!"

After saying that, he hung up the phone and drove back.

Back in the seventh game, he found He Yuzhu and said:

"Zhuzi, are there any other prototypes?"

He Yuzhu did thirty, but still nodded:

"Yes, I made a total of twenty for you, and I made ten for my own family.

By the way, this one also comes with a matching charger. This is the charger, and this is the plug strip.

Connect the power here, this..."

Looking at the plug strip and charging head that He Yuzhu mentioned, Gu Zhiqiu said:

"I know this, but what you did is really beautiful.

By the way, is this production fast? "

He Yuzhu nodded:

“It’s not slow, as long as the production line is up, producing millions of units a year is not a problem.

Of course, if you want more, you can add more production lines! "

After hearing what He Yuzhu said, Gu Zhiqiu said:

"Where's that signal tower you were talking about?"

He Yuzhu said to Gu Zhiqiu:

"There is no problem. The main reason is that the installation takes time and the parts are easy to produce!"

Gu Zhiqiu said:

"Okay, what I just asked are all here, right?"

He Yuzhu nodded:

"Definitely!"

Gu Zhiqiu said:

"Okay, you go ahead and get busy, I'll go get this right now!"

After saying that, he left in a hurry!

Looking at Gu Zhiqiu leaving, He Yuzhu ignored him. As long as there was nothing wrong with his mind, this country would definitely promote it...

It will not be open to the public for the time being, but it will be used by the government and the military first.

He Yuzhu doesn't care about this. After all, He Yuzhu is really not good at promoting this thing.

He Yuzhu is quite good at research.

Then He Yuzhu began to study other things, such as light bulbs, LED lights, kettles, rice cookers, induction cookers, household refrigerators, air conditioners, televisions, tape recorders, tapes, etc.

The technology is not very high, but He Yuzhu has made a catalog of these things and plans to develop them all.

These things cannot be used by people across the country for the time being, but they can indeed be exported and earn a lot of foreign exchange.

Of course, these things will not take He Yuzhu long, and now He Yuzhu is working on various machines.

Excavators, road rollers, asphalt pavers, trains and more.

These all take time.

However, He Yuzhu can theoretically know these things, but it just takes time to input them on paper.

Just when He Yuzhu lowered his head and discovered it, the country's top officials were shocked.

The teacher looked at the mobile phone in his hand and said to himself:

“Mobile phone, mobile phone, the machine in my hand, good name, mobile phone, quite vivid.
