After hearing Lin Su's affirmative reply, a smile suddenly appeared on Li Zhengze's face.

In this era, if both parties have seen each other's parents. Then, between the two people, it is basically a success.

That's why Li Zhengze cares so much about letting Su Bai go to their house.

"That's great, when I go back today, I'll talk to my parents about this time. ”

"They haven't been too busy lately, but didn't you, the other day, say that you want to follow up on a new project?"

"Well, when you have time, I'll go back and talk to them, and when it's time to finalize a time when both sides are free, how about you go to the door again?"

Li Zhengze can be said to have thought everything about Lin Su.

After hearing his words, Lin Su felt a little embarrassed in his heart.

A junior like her, if you want to come to visit, of course, you have to pick the other party's free time.

But let Li Zhengze say this, why do you need to let her parents accommodate her.

"That's not good, besides, even if I want to follow up on the experiment, it's not bad for a few days, it still depends on when my uncle and aunt have time. ”

Hearing Lin Su's words, the smile on Li Zhengze's face became more real.

Lin Su is willing to think about it so much, which shows that she really takes herself to heart.

"Okay, I'll go back and ask. I'll give you a few hours when you're free, and you can choose one when you're free. ”

After finalizing with Li Zhengze, I want to visit their home. Lin Su got out of his car. Back in school.

Just like what Lin Su said to Li Zhengze just now, she really wants to follow up on a new project now, that is, wireless communication technology.

To say that going back to this time, what made Lin Su feel most uncomfortable was probably that there was no shopping software, no communication software, and no takeaway software. A lot of things have become a little inconvenient.

Even making phone calls, because not every household can afford to install a telephone. So, someone also needs to convey it from the middle.

When I was in the country before, I didn't feel anything. Now she is in the capital, and her relatives are in other places. Lin Su is very nostalgic for the video function of the mobile phone.

Of course, there's no way she's going to do it right now. Even if she can make it, there are not so many base stations and satellites in the country that can help her realize this function.

However, she could have tried to make the most basic mobile phone, which is a phone with calling and texting capabilities.

Because I already have a goal in my heart, so. Lin Su asked the system to find out some relevant books and materials for her from the mall.

After Lin Su returned to the dormitory, he began to read without sleep or food.

Although Lin Weiguo was in the capital, Lin Su felt very happy in his heart. But I have to say that he did slow down Lin Su's experimental progress a little.

After simply looking up some information and collecting some data, Lin Su took out a blank notebook and began to list his own ideas.

There are three problems that exist.

The first aspect is the switch automation concept. In most rural areas and county towns, people still use crank handles, and when making calls, they need to go through the post office transfer desk, which is very inefficient.

Before, Lin Su called home more than a dozen times, and it would be good to be able to connect once. Even in big cities, there are many calls that cannot be reached every day, and there are even many calls that have to be connected after an hour.

The first thing you need to do to improve efficiency is to automate your switches.

The second aspect is aimed at information transmission, and it is necessary to carry out large-scale transformation and construction of the existing communication network. This is not something that can be done with technology. To lay a large-scale communication network covering the whole country, not only state support is needed, but also a lot of money.

The third aspect is the improvement of the telephone itself. Lin Su still remembers what she had seen before, when mobile phones first appeared, not only was the technology not up to par, but also the price was very expensive.

So, she first had to reduce the cost of producing phones as much as possible and solve some of these technical problems.

Of course, the most important thing now is to solve the first problem.

In this way, the existing phone can make more and more convenient calls before the second problem is solved.

And the simplest, of course, is the third problem, which is just a transformation of the phone. For Lin Su, who has a system, it is not a problem.

As for the second question, Lin Su felt that she could hand over her results to the state after the first and third problems were resolved, and let the country help solve them.

After all, only on her own. There is no way around this.

Lin Su put down the pen in her hand, looked at the neat and neat few questions listed in her notebook, and already had a decision in her heart.

Of course, the most important thing now is to meet Lee Zhengze's parents. After meeting his parents, he can apply directly to the laboratory. Then, let's solve these problems one by one.

Here, Lin Su was concentrating on his experimental process.

Over there, Li Zhengze returned home with a smile on his face.

When he got home, his mother, Xie Yuhong, was sitting on the sofa watching TV.

I saw him come in with a smile on his face. Xie Yuhong put down the melon seeds he was holding in his hand. He sat up straight and asked him, "What's the matter? Send Su Su's father back? Looking at your current appearance, you should not be able to behave less in front of others, right? What is his impression of you?"

Although from Lee Zhengze's expression, you can guess a lot of questions. But as a mother, Xie Yuhong still has some worries.

Hearing Xie Yuhong's question, Li Zhengze, who was just smiling. At this time, he showed a big smile to Xie Yuhong.

"Needless to say, Uncle Lin has a good impression of me. Moreover, I have already talked to Su Su just now. See when you and my dad have time, she's going to come and visit your second elder. ”

Hearing Li Zhengze's words, Xie Yuhong's face suddenly showed a smile of surprise.

She had mentioned it to Li Zhengze before, hoping to find time to take Lin Su home. However, Lee Jung-taek has not agreed.

During that time, she was always a little worried. I'm afraid that when I suddenly heard Li Zhengze say that he was separated from Lin Su.

Now, hearing that Lin Su was willing to come over, she was relieved.
