Coming out of the machinery factory, the four of them went directly back to the courtyard.

No way, such a large pile of raw materials still has some weight.

After arriving home, Gu Baozhu learned from his father and mother that the Song family and his wife had left after they left.

They had already made an appointment to meet in three days at the Friendship Hotel on Chang'an Avenue.

The reason why the time was set three days later was because Gu Baozhu's three brothers were not in Beijing, and it would take a certain amount of time to rush back.

When Zhang Xiuying talked about her brother, Gu Changping pulled his face and expressed his dissatisfaction.

Zhang Xiuying ignored him and continued to speak.

She said that the direct relatives of the Song family will come at that time, and they will invite relatives and friends to participate when it is time for the official recognition banquet.

Gu Baozhu felt that there was no need for this, and was beaten by her mother.

Her mother said that the Song family could only show their attention to her by doing this.

If you confess your relatives so unclearly, you don't take her to heart.

"Mother, the eldest brother has been able to get out of bed and walk around recently, and the time will call the eldest brother too."

"Of course." Zhang Xiuying took it for granted, "Your eldest brother is the most promising person in our old Gu family, and with him, he can also help us suppress the field." ”

"Anyway, we can't let the Song family think that you have climbed high."

Gu Baozhu was unhappy, "Mother, where do you want to go, even if you know each other, I will live with you in the future, not to mention that our family is not bad, what is high or not high." ”

Zhang Xiuying glanced at her, "People are terrible." ”

"Okay!"

Seeing this, Gu Baozhu could only raise his hand and surrender.

She understood what her mother meant, and she just wanted to tell the Song family that their Gu family was not a real countryman.

She is also a delicate girl who grew up in the palm of the Gu family's hand, and she can't let the Song family look down on her.

"Seeing that you went out in a hurry this morning, and brought back so many iron bumps?"

"What are you going to do, but I've heard from the Guardians, these iron lumps have cost a lot of money."

Zhang Xiuying couldn't help but nag, "It's not like this to spend money when you have it......"

"Mother, just look at it, soon this pile of iron lumps will become treasures, and then you will know whether the money is worth it."

Gu Baozhu grinned, didn't explain, and pushed her out.

"I'm a little messy here, you go out and chat with a few sisters-in-law first, I'll be busy first."

Zhang Xiuying nodded her head, looking helpless, "Okay, you are busy, don't be too tired." ”

The girl likes to tinker with these iron bumps since she was a child, and she has really made a lot of good things over the years.

So it's no surprise that she can even tinker with a radio and a bicycle, and her daughter is definitely smart.

What Gu Baozhu wants to do is a remote-controlled plane, this thing is very simple.

However, although the materials are available, many of them cannot be used directly, and they need to be modified.

Then she found a problem, although she had the tools, she could change some parts.

However, some parts still need some technical equipment to be modified, and she has these equipment in her hands, but she can't take them out and use them.

Gu Baozhu held his face and couldn't help frowning, careless.

If he just went directly to Director Guo, he would probably blow her out!

What to do?

Gu Baozhu thought about it, and suddenly his eyes lit up.

She can trade technology for the right to use the laboratory, and it just so happens that the current battery can't drive this kind of small plane, and she plans to make a new battery.

She can come up with a battery technology that is more advanced than the technology on the market, and exchange it for the opportunity to use the laboratory with Director Guo.

Well, she's such a clever little clever ghost.

As for whether it will be appalling, then don't worry.

The most important thing in this era is genius, coupled with her previous outstanding performance in all aspects, it seems that the development of a new battery will not be too eye-catching.

Gu Baozhu did it when he thought of it, and immediately wrote and painted at the desk.

Two hours later, a solar panel with a world-class conversion rate appeared.

She doesn't know what the utilization rate of solar cells is today, and it will definitely not exceed 15 percent.

The solar cell that Gu Baozhu is now designing has a conversion rate of up to 20 percent.

It's not that it can't be higher, but with the existing materials, it is very achievable, even if it is this 20%, if you want to spread it on a large area, it is a difficult job.

In order to be able to use the equipment of the machinery factory, Gu Baozhu also fought hard.

In addition to the design drawings, she wrote some relevant information, and then packed up and prepared to go to the machinery factory.

"It's only been a long time since you came back, and you're going out again?"

Zhang Xiuying looked at the big sun outside and couldn't help frowning.

If you go out on such a hot day, you can't get heat stroke?

Gu Baozhu smiled, "It's a little trivial, I'll go out, don't wait for me at noon, I may come back later." ”

"And what about your lunch?"

"It's simple, I'll go to the hotel to solve it when the time comes."

Zhang Xiuying didn't say anything anymore when she heard this, but just told her to be careful, and then continued the work at hand.

She is also idle, and this is her own house, so she is even more handy when she cleans up.

Gu Baozhu went out and directly called a taxi and went straight to the head of the machine.

"Why are you again?"

The old man of the doorman couldn't help but wonder that this little girl had only left the machine factory two hours ago.

Why is this coming back again, is it possible to find the factory director?

"Uncle, I'm looking for Director Guo."

"Little girl, didn't you just come here?"

Gu Baozhu nodded, but he didn't mind the old man's curiosity, and explained unhurriedly, "Didn't you suddenly remember that there was still something to do, so you didn't rush here, can you help me inform Director Guo?" ”

"You just said that Gu Baozhu was looking for him, and he was in a hurry." She thinks that solar cells are indeed a 100,000 urgent thing.

"Then you wait, I'll go to the factory director now."

Gu Baozhu was not an employee of the machinery factory, so he couldn't enter and leave the machinery factory at will, but he didn't care and nodded.

Then she saw the old man walking like a fly, but he was not seen for a few minutes.

The old man's speed was very fast, and he came back in no more than fifteen minutes, and he was not followed by Director Guo, who she was thinking about.

"Comrade Gu, I heard Comrade Luo say that you have 100,000 urgent things to look for me?"

"Yes, it's really a hundred thousand urgent." Gu Baozhu looked around and couldn't help frowning, "Director Guo, are you sure you're talking here?" ”

Guo Maoling was stunned, before he came out, he thought that this little girl had repented and wanted to return all those spare parts, for Lao Kang's sake, it was not impossible.

It's just that I didn't expect it to be like this, does this little girl really have a hundred thousand urgent things?

"Can't you say it here?" He blurted out subconsciously.

Gu Baozhu shrugged indifferently, "It's not impossible, it's just a design drawing of a solar panel, and it's not a high-tech technology." ”

"Oh, solar panels, it's really ......" Guo Maoling stopped abruptly halfway through his words, and subconsciously looked at her, "Comrade Gu, you said, you just said ......"

Gu Baozhu nodded, "I did say solar cells......"

"Let's go in, let's talk, let's talk!"

Where can Guo Maoling let her continue to say that this kind of technical problem, or related to solar cell technology, whether it is true or not, he can't be careless.
