On the morning of the first day of the Lunar New Year, Yao Ruixue did not have the benefit of sleeping lazy, and was pulled up from the bed by the uncle when she was slightly bright, and went to pay New Year's greetings to the relatives and elders in the village.

has been coming back from the ancestral hall of the Yao family to worship the ancestors, it is lunch time.

After lunch, the four brothers and nephews had to follow the sisters-in-law back to their parents' house and stay until the third or fourth year of the new year.

The lively home was deserted all of a sudden.

"Senior brother, when will you return to the capital? Walk with the stones tomorrow? ”

Yao Ruixue couldn't help but look at it, Shi Hongfei, Bai Junfan, and Bai Shige asked Bai Junfan.

Tomorrow, Hongfei will take Yu Gang, Yan Guangping, and Shi Chengdong to leave Qingshan County together.

Brother Bai Shige is also a train ticket back to Zhou City tomorrow.

Well, she has to wait for the uncle to make a decision, and when the uncle wants to go to the capital with Yao Ruixue, the uncle has not yet made a decision.

Why, Yu Gang, they are not here?

That's because of lunch, so they took more than half of the cart of medicinal wine and the research specialties that Liu Lao needed and went to Qingshan County.

Therefore, only Bai Junfan and Bai Shige were left.

Bai Junfan didn't answer, but stood up directly, went to his room, took out a notebook about ten centimeters thick, put it in front of Yao Ruixue, and said with a serious face: "When I go back to the capital, it all depends on whether you can solve this." ”

It was a correspondence research note left by the master, which was very messy at first, but Bai Junfan sorted it out little by little after discovering it.

As for why he suddenly took it out for Yao Ruixue to explain, it was because he put forward a very important idea in his master's notebook, and that idea was discovered by Yao Ruixue and gave a little answer.

Of course, there are also Bai Junfan, Shi Hongfei and Uncle who have an in-depth understanding of Yao Ruixue, so they dare to show Yao Ruixue the new most communication materials that they have been studying with their teachers for many years.

"Huh?"

Yao Ruixue really didn't understand Bai Junfan's movements, until she looked at the information in the notebook in a daze, her eyes widened, and she asked him in disbelief: "Senior brother, are you crazy, how can I solve this thing?"

I don't understand! ”

Yao Ruixue really doesn't understand, she only knows that when the master is teaching her studies, he will do some small research and small inventions from time to time.

But those memories are all long, long years ago.

Besides, Yao Ruixue is a hands-on waste, whether it is research or invention, Yao Ruixue has never been involved, let alone interested.

Yao Ruixue couldn't understand a lot of professional knowledge in the notebook.

It's just that after flipping through it, Yao Ruixue found a few familiar shadows, and knew that it should be the master's notes.

But it's none of her business, right?

"You don't need to pass it, you turn to the last thirty pages and start reading, and after reading it, just write me what you understand."

Bai Junfan also knew that Yao Ruixue, a little junior sister, could give advice to professional and technical personnel like Yu Gang, so he should have no problem in this regard.

If you say, some immature little inspiration in the teacher's notebook is amazing. Yan's words, when those small inspirations collide with what he has studied and imagined, Bai Junfan will never miss such an opportunity to study further.

Bai Junfan also knows that his teacher has traveled to many countries and has an extreme love and research for the traditional, bold and innovative communication equipment of those countries.
