Today, in the vast rural areas, the threshing work of rice and wheat is still very primitive.

Let’s take the threshing work after the wheat harvest in the north, which He Yuzhu is most familiar with.

The entire wheat harvest takes almost a month.

Before the wheat is harvested, the wheat field must be prepared.

In the wheat harvest field, mules and horses must be used to pull stones to crush the wheat field, so that no dust can be raised.

After leveling the wheat field, it’s time to harvest the wheat.

The harvested wheat is pulled to the wheat harvesting field with a field cart, and then the mules and horses are used to pull the stone to crush the harvested wheat straw.

In this way, the wheat grains fall to the ground and are completely separated from the wheat straw.

At this time, you need to separate the wheat straw and sweep up the wheat grains with a broom.

The harvested wheat grains are spread out in the wheat field and exposed to the sun.

Only after the wheat grains are dried can they be bagged or returned to the warehouse.

In short, wheat harvesting is a long and troublesome job.

It takes almost twenty days or even a month to work on it.

If a thresher is used to harvest wheat, the wheat harvesting time can be greatly shortened.

This allowed wheat harvesting to move from its most primitive form to semi-mechanization.

In this way, the wheat harvest time can be shortened by half.

Thinking of this, He Yuzhu was particularly excited.

By the way, Section Chief Feng of the Technical Department asked Secretary Wang to send him a message, saying that their technical department had copied the entire text of Ivanov's work notes, and that the work notes could be returned to He Yuzhu.

Let He Yuzhu have time to go to the technical department and take back the work notebook.

He Yuzhu left the planting base, came to the technology department, and asked Section Chief Feng to get back the work notebook Ivanov gave him.

This work notebook is of no importance to He Yuzhu and has only commemorative significance.

But now, He Yuzhu wants to research and invent a threshing machine by himself, so Ivanov's work notes are absolutely indispensable.

After getting back the work notes, He Yuzhu chatted with Section Chief Feng for a few words and then left the Technology Department...

I don’t know whether it was because He Yuzhu had something in mind or because the system was too user-friendly. When He Yuzhu signed in the next day, the system actually rewarded him with a skill;

[Mechanical Expert Skills]!!

He Yuzhu was ecstatic.

I was really thinking about sleeping, and God sent me a pillow.

He immediately took out his pen and notebook, and based on what he had in mind, he drew the pattern of a threshing machine from the notebook.

"Zhuzi, what are you doing?"

After Chen Xueru got up and washed up, she saw her man sitting at his desk writing and drawing.

She was very curious, what was this man doing?

"Oh, Xueru, it's like this. I had a dream last night about a very magical machine."

"The name of this machine is a thresher."

"This machine can be used to thresh wheat and rice, which can greatly improve the efficiency of wheat harvesting."

"No, I took advantage of the fact that I haven't forgotten all the dreams I had last night, so I quickly drew the threshing machine I dreamed about in my notebook." He Yuzhu made up a lie for his wife.

And Chen Xueru didn't doubt He Yuzhu's words at all.

"Don't tell me, the threshing machine you drew looks like that."

Chen Xueru glanced at it from the side, smiled and praised, then went to make breakfast.

After breakfast, He Yuzhu rode his bicycle to deliver rainwater to school. He rode his bicycle to the steel rolling mill and went straight to the technology department with the threshing machine he drew.

Section Chief Feng came a little late today.

The bicycle ran out of air on the way, so I finally found a repair shop and asked the repairman to remove the tire, apply it to him, and inflate it.

Only then did Section Chief Feng arrive at the steel rolling mill.

As soon as he entered the technical department, Section Chief Feng saw everyone gathered around, talking excitedly about something.

"Xiao Wu, what's going on?"

"What are you guys doing?"

Section Chief Feng laughed and cursed.

Xiao Wu turned to look at Section Chief Feng and said with a smile: "Chief, come and take a look. He Yuzhu and Master He came up with a threshing machine after research. Master He said that this threshing machine can thresh rice and wheat. 0.2 can greatly save wheat harvest time."

Hearing what Xiao Wu said, Section Chief Feng was very curious.

He also came over to the crowd and stared at the threshing machine painted by He Yuzhu for a moment.

Section Chief Feng was shocked!

"Master He, you are simply a mechanical genius!"

"The threshing machine you imagined is very feasible."

"Xiao Wu, hurry up and get a pen and write down every word and every idea that Master He said. Record them all."

"This may point the way for us to study threshing machines."

Section Chief Feng said excitedly.

Xiao Wu quickly nodded and agreed.

Take out a pen and notebook and write down every word He Yuzhu said.

When He Yuzhu left the technical department, Xiao Wu had already recorded many words densely in his notebook.

These words are what He Yuzhu said and He Yuzhu's conception.

After leaving the technical department, He Yuzhu had just returned to the cafeteria when Comrade Ding suddenly led a reporter and ran to find He Yuzhu.

"Master He, this reporter is Reporter Sun from the Flower Farming News."

"Reporter Sun learned from my mentor, Professor Fang, that you have researched and cultivated improved wheat and rice varieties with a yield of more than 1,000 kilograms per mu. Reporter Sun would like to interview you."

"Brother, in this midterm exam, I scored two hundred points again."

He Yuzhu borrowed Yuyu to get out of school after get off work. Yuzhu sat in the back seat and told his brother excitedly.

"Really? Our rain studies are great!"

"Study hard and my brother will send you to Qingbei University in the future."

He Yuzhu was also very happy. He rode his bicycle very fast, leaving the brother and sister laughing and laughing all the way.

He Yuzhu will not tell his sister that he just finished an interview with a reporter from the Ministry of Agriculture this afternoon.

He wanted his sister to see his name in the newspaper, and she wanted to give Yu Yu a surprise.

The brother and sister came to the silk and satin shop, and Chen Xueru was dealing with the guests who came to visit.

Many of these customers are repeat customers.

Because I had bought fabrics from Chen Xueru Silk and Satin Factory before, and the clothes made were of good quality, I introduced relatives and friends to Xueru Silk and Satin Factory.

Most of their customers were women. They were surprised to see that Chen Xueru's silk and satin shop had added tailor-made clothes, as well as new ready-made clothes, which attracted many of them.

Some customers buy cloth and then have their clothes custom-made.

Some customers are interested in the finished clothes on the shelves and want to try them on.

Chen Xueru and Dong Mei were busy greeting these customers together, and she didn't even notice He Yuzhu and Yuyu coming back.

He Yuzhu brought the rainwater to the backyard of Silk Village.

Parking the bicycle in the small courtyard, He Yuzhu went to prepare dinner, and Yu Yu went into the house to do his homework.

Chen Xueru is almost done with the busy work ahead. Dinner is ready at He Yuzhu's place, and homework at Yu Yu's place is also finished.

The sky was darkening and the silk and satin shop was closed.
