Chapter 68

After saying that, Song Shuqian did not talk to the four people opposite her. She took out an apple and started eating.

The other three people were too embarrassed to talk to her.

After all, the short-haired girl was with them. But they also decided to stay away from the short-haired girl in the future.

At this time, people looked down on the third party who destroyed other people’s families.

It was almost time for dinner, and the carriage became lively, and Wei Jianguo was woken up.

He might still be a little dazed after just waking up. Song Shuqian handed him a kettle with spiritual liquid, “Drink some water to wake up, and go to sleep at night. “

Wei Jianguo hummed lightly, still reacting.

After drinking a few sips of water, he slowly came to his senses. “How long have I slept?”

“Three hours, you’ve been too tired recently, you should have a good rest.”

After Wei Jianguo woke up, he accompanied Song Shuqian to the toilet. It was really dirty, and Song Shuqian went straight into her treasure gourd. No wonder Wei Jianguo bought several spittoons and asked her to put them in the treasure gourd.

Song Shuqian didn’t look very good when she came out of the toilet. Wei Jianguo knew the reason at a glance, and it was a bit funny, “It’s okay, leave it to me.”

Song Shuqian’s face flushed, “I’ll do it myself.

” Wei Jianguo took her hand, not disgusted at all, “I’m your husband, leave these things to me, don’t I also clean the toilets in our yard? It’s the same.”

Song Shuqian couldn’t do it herself, so she could only nod with a red face.

“Are you feeling uncomfortable in your stomach?”

“No, if you didn’t remind me, I wouldn’t even remember that there was another one in my stomach.” This child is worry-free. Since Wei Jianguo came back, there has been no reaction at all.

When the two returned to their position, it was already dark outside.

“It gets dark earlier here, I wonder if the sunrise is also earlier”, Wei Jianguo found a topic to chat with his wife.

Song Shuqian explained to him, “The time of sunrise and sunset is affected by the season and latitude. In winter, our country is near the perihelion, the daytime is short, the sunrise is late, and the sunset is early. In summer, our country is near the aphelion, the daytime is long, the sunrise is early, and

the sunset is late. Latitude also has an impact. High latitudes have late sunrise, early sunset, and relatively short daytime. Low latitudes have early sunrise, late sunset, and relatively long daytime.”

Wei Jianguo didn’t understand, “What is latitude?”

“Latitude refers to the angle between a certain point on the surface of the earth and the equatorial plane. The latitude of Harbin is between 44- and 46-degrees north latitude; the latitude of Huludao is between 40 and 41 degrees. This is just an approximate range. The specific needs to be accurate to seconds. I don’t remember it.”

Song Shuqian said while explaining to him in a small notebook she carried with her. She

also talked about the longitude.

It was half an hour later when she finished.

Wei Jianguo likes his wife to tell him all kinds of things at any time. His wife is like an encyclopedia. He can ask his wife if he doesn’t understand something.

It is unknown when these things will be used.

Even though their voices were very low, the four people around them also heard a few words.

They were in awe.

They had never heard of these things.

Even though the school is closed now, people with real insight will still admire intellectuals. The view that everything is inferior except for reading for hundreds of years is not so easy to be overturned.

After the couple finished talking, they started to eat.

Dinner was roujiamo with porridge, which could be eaten after heating in the same way.

Their food was good, but the taste was light and did not attract the attention of others.

Instead, the cucumber that Song Shuqian ate after dinner attracted an old lady.

She came over and said to Song Shuqian, “Girl, I feel carsick. Give me one of your cucumbers.”

Song Shuqian didn’t let Wei Jianguo speak, and said with a smile, “Auntie, I’m pregnant, and I brought some refreshing food with me to relieve my pregnancy reaction. If it were normal, I would give it to you if you wanted it, a cucumber is not worth much. But now it’s special, I don’t bring much, and I can only afford to eat one after dinner to relieve my pregnancy reaction. You can go to the dining car and have a look, they should have it.”

The auntie looked at Song Shuqian’s flat belly, “Are you really pregnant?”

“Is it true? A few months ago, it was just the time when I had a reaction.”

The auntie left unhappily, and you will lose if you fight with a pregnant woman for things.

Wei Jianguo enjoys his wife’s protection for him. Usually he stands in front, and it feels good to be protected like this.

After dinner, the two of them still stood in the aisle.

It was completely dark outside, and nothing could be seen.

Song Shuqian looked at the darkness in the distance, and she didn’t feel scared, but a little curious. She used to read in the storybooks that there would be all kinds of monsters in the wilderness at night. Of course, she knew that she couldn’t say these things, so she just thought about it in her heart.

Worried that his wife would be emotional and have wild thoughts again, Wei Jianguo thought it would be better to let his wife give him a lecture.

“Wife, how does a train start?”

“The train we are riding now relies on a steam engine. There is a boiler on the train. Workers add coal to it, heat the water into steam, enter the cylinder, push the piston, and give the train power. From a distance, the chimney on the train is always smoking.”

The original owner, Song Shuxi, used to work in the design department of a machinery factory. She did not get in through connections, but through real talent and knowledge. These simple mechanical principles were not difficult for her. After Song Shuxi came here, she digested all the memories of the original owner and studied more deeply.

Therefore, these questions are easy to come by.

Maybe men are naturally interested in machinery. After Wei Jianguo found that his wife understood these, he pulled Song Shuxi to the bunk and continued to ask, “Wife, how do you control the speed of the train?”

This chapter is not over yet, please click on the next page to continue reading! “There are many ways to do this. One is to adjust the gear like a car. Cars have first, second and third gears, and trains also have them. The second is to adjust the steam supply. For slight speed changes, just adjust the throttle valve. For large speed changes, you need to operate the steam valve. The third is emergency braking. There is an emergency brake handwheel, or air braking. The last method is to control the pressure of the boiler, which is to put coal.

There may be other things I haven’t thought of. If you are interested, you can ask the teacher when you have related courses later.”

Wei Jianguo’s eyes are full of stars when he looks at his wife. His wife knows everything.

“Wife, you are amazing,” Wei Jianguo said sincerely.

Song Shuqian drew him a schematic diagram of the principle of the steam engine, which he kept as a treasure. He planned to take a good look at it and remember everything his wife said.

Song Shuqian was worried, “I’ll keep it and give it to you when I get back.”

Wei Jianguo had no objection.

Seeing that he really liked it, Song Shuqian drew him a diagram of the mechanism of the bicycle and the principle behind it. This should not involve any confidential information, so he can look at it at will.

Just now, they talked about the steam engine. They spoke very quietly and were very close to each other, so only the two of them could hear it.

It was only at this time that Wei Jianguo realized that his wife was actually proficient in mechanics.

Song Shuqian didn’t feel embarrassed to correct him. She was good at mechanical principles. Thanks to her photographic memory, she remembered everything she had seen. If she really had to operate it, she would be at a loss.

It was already very late after the chat, and Song Shuqian wanted Wei Jianguo to lie down and have a good rest.

“I’ll go to the middle bunk, so you can protect me on the lower bunk. Anyone who comes over has to pass by you first,” Song Shuqian insisted.

Wei Jianguo couldn’t get rid of her, so he carried him to the middle bunk directly, “Call me if you want to come down.”

“Yeah.”
