Chapter 69: question

Qiqu Pavilion Workshop.

"Xiaoxuan, the old man, I speak more straightforwardly. Don't be surprised.

Although your scooter is creative and novel, but in the end this thing is just

a child's joke, and it is useless for the people's livelihood. Your roller

bearing is useful. Great, since you have the talent in this area, you should

study more things that are beneficial to the people."

After seeing a few people sitting down, Uncle Fu began to preach to Li Zexuan

earnestly. Li Zexuan was very speechless. This old man's temperament was

really straightforward. If he were replaced by someone with a small belly, he

would definitely hate him for it.

Fortunately, Li Zexuan is not such a person, he still agrees with Fu Bo's

words.

"What Fober taught is that this scooter is just a plaything that I wanted to

coax her sister at the beginning. Of course I will not only do this in the

future."

Fu Bo nodded comfortedly and said: "Well, a child can be taught."

Li Zexuan remembered another purpose of coming to the workshop, and said: “I

went to my village yesterday and found that this year’s fields were

particularly difficult to cultivate due to little rain. It is estimated that

some farmers will miss spring ploughing. Brother Shaoning and Fu Bo know. This

matter?"

Yan Shaoning looked down and said solemnly:

"This situation doesn't just happen in your Zhuangzi, but in various counties

around Chang'an. According to my father, this incident has alarmed the court,

and your Majesty has already learned about it. It is making people from the

north. Several prefectures and counties in China transferred a batch of cattle

to Chang'an and then distributed them to farmers, so as not to let farmers

miss spring ploughing."

Fubo also nodded and said: "The old man has also heard about this, but

Xiaoxuan, what is your purpose in bringing it up? We can't help much with this

kind of thing, we can only rely on the court."

Li Zexuan stood up and disagreed with him: "Uncle Fu's words are wrong. As the

saying goes, if you want to do good things, you must first sharpen your tools.

As a craftsman, you must also have the craftsmanship spirit. You have just

educated the kid. Things that are beneficial to the people's livelihood, then

why can't we make more useful farming tools for the people?"

Fu Bo raised his eyebrows. He has been in this field for so many years, but

today he was preached by this little doll. He was a little displeased with

arrogance and frowned:

"You kid said it is light and handy. The straight-wheel plow I used in the

Tang Dynasty originated in the Han Dynasty. After several improvements, it is

already the most advanced tillage tool. How can there be a better tool than

this."

"Fu Bo said, the kid can't agree, how can craftsmen not seek innovation, how

can they do the things that predecessors planted trees and future generations

can enjoy the shade, how can they know that they can't make better farming

tools without trying?"

Fu Bo was dissatisfied and said: "So, can you make better farming tools?"

Li Zexuan could also see that this old man was stubborn, not to say how bad

his heart was, but that he did not allow others to question him in his best

field. This kind of person Li Zexuan has seen a lot in his previous life,

generally in various fields. Daniel has such a stinking problem.

At the moment, Li Zexuan didn’t talk nonsense. He directly took out the

already drawn Quyuan Plow drawing from his sleeve, spread it out on the table,

and said to both of them:

"This is a kind of more labor-saving plough that I saw in Hanjiazhuang

yesterday when I saw farmers plowing the land with straight shafts. Today I am

trying to find a workshop to produce a batch as soon as possible. Brother

Shaoning, Uncle Fu, come and have a look. ."

Yan Shaoning and Fu Bo can't wait to get together to look at the drawing. The

first time Fubo saw this drawing technique, he frowned and wanted to ask Li

Zexuan, but he was a little embarrassed to ask. He had just quarreled with Li

Zexuan, and he couldn't hold back his face.

Yan Shaoning is very familiar with this painting method. He carefully read the

content of the drawing, then closed his eyes and meditated, imagining the

structure of the plough in his mind, but after a few breaths, he opened his

eyes.

"Xiaoxuan, your plough should have evolved from a straight shaft plough? I saw

that you made changes to the length and shape of the shaft, and installed a

roulette on the head of the shaft. With this structure, I But I’ve never seen

it before, and I can’t say whether your plough or the straight-wheel plough we

use is more labor-saving."

At this time, Uncle Fu saw what Yan Shaoning was talking about. Obviously he

could understand this kind of drawing. Uncle Fu was very depressed. He had

been a craftsman for a lifetime, and he also had his own pride in this field.

Not as good as these two little dolls.

In fact, after Yan Shaoning finished speaking, he noticed that Fu Bo was still

staring at the drawing, and after a little thought, he understood what was

going on. He patted his head and said embarrassedly:

"Uh, Fu Bo, I forgot to tell you that this drawing method was created by

Xiaoxuan. These three pictures represent the shape of the object seen from

three directions..."

Yan Shaoning began to popularize the knowledge of the three views to Fober.

Fober has been studying this field for so many years, and he can understand

everything with a little dialling. Even though he did not agree with Li

Zexuan's point of view before, he also agreed with Li Zexuan's drawing method.

He nodded, then looked at the picture again.

Li Zexuan also explained to the side at this time: "Bo Fu, brother Shaoning, I

call this kind of plough a Quyuan plough. It consists of eleven parts, namely

the ploughshare, the plough wall, the plough bottom, the presser, and the

plow. Forehead, plow arrow, plow shaft, plow review, plow construction, plow

tip, plowshare."

Li Zexuan explained to them one by one while pointing to the drawing. Both of

them listened to him seriously. Even if they could understand the drawing,

they would definitely not be able to keep up with Li Zexuan in terms of their

understanding of this yin plough.

Li Zexuan continued: "I changed the long straight shaft into a short curved

shaft, and installed a freely rotating plough disk on the shaft. This not only

makes the plough frame smaller and lighter, but also facilitates turning and

turning, and the operation is flexible. It saves more manpower and animal

power."

"In addition, I also added the plow review and the plow arrow. If you use the

push plow review, you can make the plow arrow go down and the plowshare will

penetrate deeper into the soil. If you lift the plow review and make the plow

arrow go up, the plowshare will penetrate the soil slightly. The combination

of plow review, plow arrow and plow arrow can adapt to the different

requirements of deep ploughing and signed ploughing."

"The plough wall can not only crush the soil, but also push the ploughed soil

to one side, reducing the resistance of the plough forward. Combining these

improvements, the curved plow can save at least 50% of the effort than the

straight one."

Li Zexuan faced the drawing and talked freely. The two of them nodded

frequently as they listened. Finally, Fu Bo couldn't help but say, after

reading the book www.uukanshu.com:

"Your design is quite new, and it sounds reasonable to hear you say that, but

we are just talking on paper now, and no one knows if it is more labor-saving

and better."

Li Zexuan wanted to tell him that these are theoretically based. Draw a force

analysis diagram and do a little calculation according to the formula to know

which is more labor-saving. But if you tell them this way, you have to spread

the knowledge of engineering mechanics with them. This is not something that

can be said clearly in a few words.

Li Zexuan can only say: "Fu Bo, what you said is not unreasonable, but

practice is the only criterion for testing truth. Rather than arguing here, it

is better to make a batch to test it. You may know that ploughing is more

labor-saving. Yet?"

Fu Bo muttered: "Practice is the only criterion for testing truth. Xiaoxuan,

what you said makes sense, so let's try one out first."

Li Zexuan folded his hands and said with a smile: "Then Lao Fubo will first

build 20 curved ploughs. My Zhuangzi is in a hurry to use them. The day after

tomorrow I will take this batch of curved ploughs to Zhuangzi for an

experiment."

Fu Bo frowned and said, "Xiao Xuan, how much do you want to make for the first

time?"

Li Zexuan smiled confidently: "Fu Bo, I am very confident in Quyuanli. The

farmers of Hanjiazhuang are waiting for spring ploughing. I don't have time to

try them one by one. I believe Quyuanli can solve the immediate need."

Fubo hesitated for a moment, nodded and agreed: "Okay, since Xiaoxuan said

that, the workshop will work overtime in these two days to produce 20 quyuan

ploughs. The day after tomorrow, I will go to Hanjiazhuang with you to see how

it works. "

"I also need to go."

Yan Shaoning added quickly. If this Qu Yuan Plow is really as magical as Li

Zexuan said, then this will definitely be a major event that will shake the

ruling party and the opposition, and he must see it in person.
