For several days, Li Xingxing was studying and making up for the lessons in the room, and he was dizzy when he learned.

Why can't she be a poor student?

Just eat, drink and have fun, don’t have to chisel the wall and borrow light, don’t have to hang your head and bend the beam and cone.

She is good at foreign languages, but she is a little weak in science and is not bad at math. She has the best foundation for her grandfather. When she encounters something she doesn't understand, she stays happily and goes back to school to find a teacher to solve it. She is ready to throw out the textbook to study other subjects. However, Xia Mingxing's answers quickly and well. After listening, she thought that she wouldn't be able to do it.

He has rich knowledge and can be easily taught, which is better than the school teacher, so he keeps burying into her head.

He also used some of the parts they bought when purchasing supplies to assemble the telegraph machine.

"Is it just a telegraph machine with Morse password? I used to watch TV with my grandfather, watch anti-Japanese war movies and spy movies. The small telegraph machine inside often sends intelligence information thousands of miles away, which is amazing." Li Xingxing felt very novel and randomly pressed the buttons on it, "How far can the radio waves of the telegraph machine you assembled?"

Xia Mingxing smiled, "It's absolutely fine to transmit thousands of kilometers."

Li Xingxing admires him very much.

Xia Mingxing touched her head, "It is related to the size of power. The greater the power of the radio station, the further the message spreads. A long, long time ago, I used long and medium waves at the beginning. Later, I encountered difficulties and found that short waves could propagate thousands of miles away using the reflection of the ionosphere in the atmosphere, and large radio stations could achieve global communication."

Li Xingxing was confused when he heard it, "What is the ionosphere?"

"After the atmosphere is exposed to sunlight, it forms a charged layer of air, called the ionosphere, about 60 kilometers to 2,000 kilometers from the ground." Xia Mingxing patiently told her, "When radio waves enter the ionosphere..."

Li Xingxing quickly stopped: "Stop! I won't be a telegrapher, don't explain to me."

She was afraid that Xia Mingxing would continue, so she quickly changed the topic: "When we were about to arrive in Shanghai, we sent a telegram to our father on the sea, asking him and his mother to come to the dock to welcome grandparents!"

Xia Mingxing is planning to do this.

Whether it is the tens of millions of foreign exchange they brought back to China or the two sets of 90% of the new industrial equipment, it is very important. Chen Xiangyang must be notified to make arrangements early and prepare residences for the two elders in advance.

Before they set off, due to the uncertain return date, they did not notify the relevant person in charge in China and might encounter trouble when entering the country.

"I will teach you how to send a telegram at that time." Xia Mingxing teased her young wife.

Li Xingxing shook his head wildly, "I don't want it, I don't want it, you can send a telegram!"

Remembering Morse’s password is a waste of brain cells!

"Is it so difficult to study as smart as you?" Xia Mingxing banged her head with her fingers, and her movements were very light. "If you don't study hard, how can you take the postgraduate entrance examination? How can you get a high education?"

Li Xingxing casually said: "It's enough for college students. I used to want to take the postgraduate entrance exam because I didn't want to be a teacher."

Soul engineers are not so easy to be, and they need to face various future risks.

Xia Mingxing looked helpless, but he didn't continue.

He felt that Li Xingxing was not interested in studying because she was crazy about playing abroad during this period. After returning to China, she had no entertainment and was not happy to go shopping. She should be able to calm down when she was doing nothing.

After being silent for more than ten seconds, he said, "Take out the arms, I will sort them out and put them in an empty suitcase."

When organizing jewelry, some empty suitcases were left for secondary use.

Li Xingxing exclaimed, "Brother Xiaoxia, are you planning to pass the arms through the Ming Road? Put it in my suitcase, which can not only mess with grandparents, but also facilitate handing in when entering the country."

Xia Mingxing nodded, "This batch of arms is of great research value and must be handed over."

Li Xingxing smiled, "I understand, I understand."

What a copycat country!
