The eldest daughter of a peasant family: They are all my sisters’ passers-by

Lan Wangshu didn't want to do it herself, so she asked Lan Wangyu to help. She was looking forward to what kind of surprise this little guy would give her.

The two people, one big and one small, moved quickly and well together, and in the blink of an eye they had assembled a small three-legged plow.

"Sister Wangshu, take a look and see if this is the case."

"That's basically right. Let's try putting some sand in there. I'm afraid we need to design a mechanism to control the amount of seeds."

This mechanism was left for Lan Wangyu to think about, so it was not drawn directly when the blueprint was drawn.

Cang Wenyuan tried it twice and felt that this thing had made great progress. It was indeed easier to use and only one person could do it. There was no need to bend over and dig trenches all the time. One trip was equivalent to nine trips.

"But where should this mechanism be placed?"

"Xiao Yu, what do you think?"

Cang Wenyuan asked Lan Wangshu, and she asked Lan Wangyu without blinking. He even thought that the little girl was crazy for asking a child.

Lan Wangyu wrinkled his face. His smooth skin had no wrinkles, but some muscles were bulging. He looked like he was in trouble.

"Make the hole smaller so less seed comes out. If it's not enough, you can tilt it a little more."

“That’s indeed a solution.”

Cang Wenyuan nodded, but the effect was still not ideal and not easy to operate. Everyone's strength and angle would not be so uniform, so there would always be some errors.

"It's a familiar problem, Xiaoyu. There's no way to standardize it. Just like making tofu, this thing should be easy to operate and not very different for anyone. Do you have any ideas?"

“That requires making a mold.”

Lan Wangshu looked at him with warm and firm eyes, nodded affirmatively, and encouraged him to continue.

Lan Wangyu held his face with both hands, squatted on the ground and thought for a long time but couldn't think of any good solution. He turned to Lan Wangshu for help in frustration.

"Sister, I don't know either."

"Then think about it slowly. I'll talk to your master. Luo Chen, take your brothers to wash up. It's time to go to bed soon."

Lan Luochen nodded obediently, holding one of their hands and leaving. Lan Wangshu didn't look at Cang Wenyuan until the bathroom door was closed.

"Just make a mold according to Xiaoyu's idea. You can make a small box here, separated by two templates, one in front and one in the back. When it is straight, start from the top, and the seeds will just fill the small box. When it is cut diagonally, close the top and open the bottom, and the seeds in the box will fall out."

Cang Wenyuan was a little bit unbelievable. He looked at Lan Wangshu seriously. This solution was not difficult to think of, but it was indeed difficult to think of it so quickly. No wonder his father said that it was a pity for Lan Wangshu to be a girl. So this was what he meant.

"Sister Wangshu is indeed a great person. If she were a man, she would have accomplished great things."

"It's the same with girls. They are not any different. They all have their own paths to follow."

"This girl is really transparent."

Gao looked at Lan Wangshu and Cang Wenyuan talking with some envy. She could also see the men's admiration for the young girl. It would be great if she could see such a look in the other man's eyes one day.

"According to Sister Wangshu, how should this mechanism be designed?"

Lan Wangshu looked at it for a while, then thought about the murals he had seen before, and kept rehearsing the operation methods in his mind. He actually thought of a design method for the mechanism, which was to add two handles to the push rod and control one block with one hand.

She hooked her finger at Zhou Xingnan, who looked behind him and pointed at the tip of his nose uncertainly. Lan Wangshu nodded, and the young man strode over and stood beside her, looking down at her.

Lan Wangshu was a little confused. The two looked at each other for a while. She curled her lips and reached out to snatch the small wooden stick from his hand.

Zhou Xingnan subconsciously gripped the wooden stick tightly, looking like it was a treasure.

"Boss, you can't do that to it. It's the most beautiful stick I've found."

Lan Wangshu looked at the wooden stick twice more, but couldn't see what was so good about it. Forgive her for not being able to understand it. She was too lazy to pay attention to Zhou Xingnan, so she just snatched it away, squatted on the ground and started drawing.

She was very aware of her own painting skills, which were indeed a bit abstract, so she could only draw and introduce them at the same time.

Cang Wenyuan nodded repeatedly as he looked at it. He understood the structure and made a decision quickly. This thing should be made this way. He had to make one tomorrow to give it a try. The wheat matter was not an easy matter. The people above were waiting and he could not be careless.

Although this official document was submitted to the Ministry of Revenue by the magistrate of Guihua County, the whole world belongs to the emperor and there are ears and eyes of the emperor everywhere, so it was taken very seriously. He was a newly-minted Jinshi and served under the Minister of Revenue, so he knew much more about every little thing than the average person.

"I will make it as soon as possible, but isn't this pushing rod a little too long? Is it necessary?"

"Make it longer first, then modify it. It would be best if you let your sister-in-law try it out. It would be best if women can use it easily too."
