Stargirl's guide to life in the 70s

From then on, the matter of Yu Jiang's apprenticeship was settled.

When he returned home at night and turned on his bracelet, Yu Jiang discovered that Lu Beiyuan had sent him a lot of messages.

From when I first got off the bus in the city: "I'm already in the city. I'm going to take the train right away. Are you still in the county?"

"I'm on the train, have you gone home?"

"It's already 9pm, haven't you gotten home yet? Why haven't you replied to the message?"

"Is Jiang Jiang sleeping?"

"Good morning, Jiang Jiang, are you up?"

"I have left province X now. I miss you so much..."

"Jiang Jiang, what happened to you? Why didn't you reply to me?"

"Jiang Jiang, if nothing happens, just reply to me!"

The latest message was sent 30 seconds ago: "I'll come back to you now!"

Yu Jiang could tell from Lu Beiyuan's tone that he was anxious about not being able to wait for a reply, fearing that if he really came back like this, he would not be able to make it back to the army in time.

Yu Jiang hurriedly replied to Lu Beiyuan: "I'm fine! Don't be impulsive!"

"I just had something to do these two days, so I didn't look at the bracelet."

The next second Lu Beiyuan's message came back: "Is everything okay?"

"It's okay, go back to your troops, don't come over!"

Lu Beiyuan, who was on the opposite side, finally stopped shouting to come back under Yu Jiang's strong request.

Yu Jiang closed the bracelet and fell directly on the bed.

Why is this Lu Beiyuan so... clingy...

The next day, Yu Jiang came to the field for the first time in a long time.

Today, Father Yu borrowed a machine from the county and organized the villagers to shell the grain together in the brigade.

Although many people in the brigade have their own shelling machines, those machines are purely manual, and there are not a few cases where the shells are still left after shelling.

Even if such shelled grain is handed in, the commune will not only directly reduce its quality by one level when collecting the grain, but the brigade will also have to hand over 10% more grain.

In order to avoid this situation, Father Yu went to the county to borrow a shelling machine that could only be used by the commune every autumn harvest.

It is not an easy thing to borrow these machines. Father Yu borrows the shelling machines from his own connections every year.

People in nearby villages are extremely envious of Fenghe Village for having such a capable captain.

Yu Jiang didn't feel anything about this, but she was just more curious about her old father...

The task that Yu Jiang was assigned today was to take the bundled grain to the shelling machine, and then naturally there would be dedicated people to operate the machine.

Yu Jiang only thinks that the current machines are really useless!

It's not an intelligent control, it just needs someone to assist you all the time.

The machine got stuck twice in one morning, and then the person in charge of the shelling machine had to disassemble the machine and clear the stuck area again.

Although the efficiency is much higher than that of pure manual work, Yu Jiang still looks down upon it.

However, during Yu Jiang's close observation, she also understood the principles of this shelling machine.

Yu Jiang had made an agreement with Lu Beiyuan before, so that Lu Beiyuan would not have to help her process the grain, and she would make a machine by herself.

After figuring out the principle of shelling, Yu Jiang took out a pen and paper and started drawing after returning home in the evening.

Yu Jiang learned that in this era, other countries already had preliminary CNC technology. That is to use electronic computers to control the operation of machines.

It's just that these technologies are currently firmly mastered by other countries, so there is almost no such equipment in the country.

But Yu Jiang is a person who traveled from the interstellar world!

For her, getting the most advanced machines is not a problem, but these things just can’t be taken out...

So Yu Jiang only changed a few things on the current machine that she found particularly troublesome. Although it is a small modification, not only the efficiency of the entire shelling machine can be greatly improved, but even the shadow of the shell will not be seen in the pile of rice after shelling.

Then Yu Jiang drew a wheat processing machine. After all, wheat has one more step to grind into powder than rice, so Yu Jiang directly drew two connected machine tools.

The wheat will be shelled on the first machine tool, and then automatically transferred to the second machine tool for grinding. The final product will be snow-white flour.

After Yu Jiang finished the drawing, he decided to find time to secretly make these two machines.

As for the materials used to make those machines, Yu Jiang is not worried at all. There are a lot of various metals in the space of her bracelet.

If it doesn't work out, she still has a set of battleships that she snatched before. If she dismantles those battleships, she can get a lot of materials!

Yu Jiang originally only wanted to make a machine himself to facilitate the supply of goods to Zhu San. I didn't want to show this blueprint to the public so early and expose my edge.

However, Lu Beiyuan learned about this when he chatted with Yu Jiang at night, and persuaded Yu Jiang to hand over the drawings.

It's one thing to get part of the bonus.

The important thing is that Yu Jiang can't always hide her clumsiness, and her own abilities are enough to support her soaring into the sky.

The two drawings that Yu Jiang took out now are just improvements based on the original ones. Although they will be eye-catching, they will not appear obtrusive.

With this foundation, if Yu Jiang comes up with anything in the future, it will not arouse suspicion.

Yu Jiang felt that Lu Beiyuan's words made sense, and she decided to go find He Zhile's brother who worked in the machinery factory tomorrow. Through him, the drawings are handed over to the leaders above.

Afraid that the people in the machinery factory wouldn't understand, Yu Jiang took up his pen again and wrote down the specific production methods and experimental principles on three large pieces of paper.

……

He Zhixing looked at the drawings handed to him by the sister next door, and he couldn't hide the shock in his heart!

When Yu Jiang came to see him early this morning, he thought it was just a small matter to help carry things, but he never expected that this girl would give him such a surprise without saying a word!

Although he is not a technician, he will naturally know some tricks after dealing with those machines.

In addition, Yu Jiang also provided an explanation, so he could also see that the drawings given by Yu Jiang could just solve the problems that have been bothering everyone over the years.

"Jiang Jiang, tell me carefully, did you really draw this by yourself? No one helped you?"

It was not that Yu Jiang couldn't understand the other party's surprise, and he explained seriously: "It was indeed done by me alone. When I was at work yesterday, I took a look at the shelling machine and felt that there were some areas that could be improved, so after I got home, I So I drew this drawing.”

He Zhixing naturally believed in the sister he had grown up watching.

"Jiang Jiang, if you believe me, I will hand over this drawing for you.

Don't worry, I'm just handing you something and I won't take any advantage of you. "

He Zhixing, who knew the value of the drawing, was also very grateful for Yu Jiang's trust in giving him the drawing directly, and immediately promised to help Yu Jiang deliver it.

"Of course I'm your brother, so I'll leave it to you."
