After leaving the teahouse, Li Su and his party continued to stroll, crossed the Minjiang River along the Fudao Flying Bridge on Dujiangyan, turned around from the west bank and then went to the south downstream to inspect.

Originally, the bridge across the Minjiang River on Dujiangyan was not built until the Song Dynasty. However, there are bridges in this time and space, which were built by Li Su in the past few years of governing Shu, and it can be fully realized in technology.

Because the Minjiang River is divided into two by the weir in this area, the narrowest parts of the inner and outer rivers are only thirty or forty feet wide (70 to 90 meters), which is already in line with the conditions for the ancients to build cable bridges or single-guaranteed wooden arch bridges and complex roads.

When Li Su built these two bridges, he combined the upward tension construction method of the cable bridge, allowing craftsmen to set up strong stone tower cables on both sides of the strait, which played a role similar to the cable-stayed bridge tower in later generations.

At the same time, it also took into account the advantages of the support of the arch circle. It spent a lot of money to allow the woodcutter to find many towering trees with thick and solid parts of the main trunk and solid parts of the trunk of the 15th meter long. Then every three trees were mortise and tenon-embed each other to form an arch.

After the bridge was repaired, it was very convenient for the people to travel back and forth, and the west bank of the Minjiang River was developed to be more prosperous. At one time, some people spontaneously wanted to establish a stone for Li Su, just like the Li Bing stone statue built in the first year of Jianning (168, the year when Emperor Ling ascended the throne).

Later, Li Su felt that she was too young and it was not auspicious to do this, so she stopped her.

Today, Zhen Yao, who was in charge of helping, proudly boasted about the envoy's achievements with Xu Shu, which also made Xu Shu have a better understanding of Li Su's kindness to the people.

The group soon arrived at the water truck workshop area where the busiest operation rate seemed to be the busiest, but before they could observe in detail, they were politely blocked by some guards:

"Please stay here. This is Zhuge's workshop. It is confidential and no one is allowed to enter. If you want to buy a comprador, you can go there and have a helper to contact you..."

When Li Su waved his hand, Zhen Yao immediately explained his identity. However, because he did not bring a token when he went out today, the people below did not dare to confirm it or neglect it. He quickly accused him and sent someone in to report it.

After a while, a woman in charge came out of the house, wearing a gauze hat and trotted, and it seemed that she was not negligent.

Li Su thought to himself: Zhuge's workshop is large enough, it takes so long to find someone. It took so much time to come here trotting.

The woman glanced at Li Su several times, recognized him, and hurriedly asked in: "I don't know how neglected the envoy will be. The envoy is interested in visiting the workshop. I'll just say something to my brother."

After hearing the other party's voice, Li Su quickly remembered that this was indeed Zhuge Zhi, the second lady of the Zhuge family. He replied casually: "It's really a man. The Zhuge family's business is so big that it is well-organized."

Today, I was just visiting Du'an County and temporarily found that your silk reeling water truck workshop can be completely stopped in the cold winter. So, let's see if there is any new business worth learning from, so I can also focus on the benefits of the people."

Li Su is very familiar with Zhuge's family. After all, Li Su had seen five brothers and sisters when Zhuge Gui died of illness and entrusted his orphans. Six years have passed in a flash. Except for the eldest lady of Zhuge's family who rarely sees them again after marrying Lu Su, everyone else is Li Su watching them grow up.

Zhuge Zhi is not very beautiful, and she must be far from the reference objects of Zhen Mi’s Bridge and Small Bridge. Even compared with Cai Yan and Zhou Ying, she is slightly inferior to that of Cai Yan and Zhou Ying. However, she is quite capable, and has a clever mind to settle accounts. She is considered to have their own strengths.

Zhuge Zhi led the group to the workshop, passed through several waterwheel workshops, and sat in the main hall of the office, served tea, and then took out the hats with great pleasure. Not only Li Su, but also Zhen Yao and Dian Wei also had seats, and they did not deliberately avoid others when talking about commercial secrets.

After Li Su took a sip of tea, Zhuge Zhicai said generously: "I asked you, naturally I will not cherish it myself. However, I have always heard from my younger brother that I have always said that three or four years ago, I promised him that "innovation should have patents." Our Zhuge family business is a copy of the patent saved. Let me count the words."

Li Su was also a little surprised when he heard Zhuge Zhi speak like this. He didn't expect that there would be such a generous appearance in this era and bargain with men without stage fright.

It seems that perhaps it is because I have seen a lot of money in recent years that I have cultivated and discovered such confidence. Otherwise, I would not be able to calm down so many men under my charge, and I would not be able to support the need for internal and external communication by relying on my confidant maids alone.

Of course, Li Su couldn't keep his word. He easily confirmed: "When did what I said not count? Besides, this was recognized by the king. As long as it was under the rule of the king, this line would be effective. Why, what "invention" did the Xianmei have made, but it is not comparable to Lingdi?

Don't worry, let's say it out - you have seen the end of those unscrupulous merchants in Jianwei County who suppressed grain prices and accumulated brothels last year? They mortgaged their land and borrowed money to speculate brothels, and finally the end of "explosive stock" was to force enforcement. I thought about it later and said that this year, I have suggested that the king set up an executive department under the Tingwei.

From the six disabled and meritorious veterans in the camp today, they choose one. They are not suitable for going to the battlefield again. They also give them some relatively idle things to do, and have a guarantee in their later years. They are specially designed to deal with mortgage speculation, bankruptcy and unpaid taxes, and maliciously owed taxes and patent fees. As long as your things are good, whoever counterfeits will not pay them money, they will come to collect the money by killing horse swords and swords."

Under Li Su's rule, the investigation methods of the copycat may be more difficult than those of later generations, but the punishment is definitely more ruthless than those of later generations.

Unless you hide deeply, don’t be caught with evidence, and you don’t know who counterfeits it. As long as you follow the clues and catch them, you will... Hehe, Li Su will let those fake and shoddy counterfeit businessmen know what cruelty is.

Zhuge Zhi was no longer worried, and got up and took Li Su to visit one of the water trucks that were under construction, and then explained to him: "The silk-reeling water trucks will be wasted in winter. We began to notice this at the end of last year. At that time, A Liang had not left. A few years ago, because the water truck volume was not large enough and the problem was not obvious. The extra production capacity was temporarily transformed and a set of wooden hammers were added to make it possible to mill rice for the people in winter.

Later, Aliang and I wanted to make a long-term solution. I thought that there were a little more white bunch of flowers in this local area this year. You have also said that these white bunch of flowers can not only be used to remove the seeds and fill the leather jacket, but also spin and weave cloth. I tried it and it was true that they could spin yarn with a spindle with a hemp rope.

So in the summer I wrote a letter to ask A Liang, and I thought about it myself, wanting to see if I could use the silk reeling water wheel for spinning. The difficulty is a bit. The silk reeling is "pulled" and the spinning is rubbed back and forth. However, after two or three years of doing this, I have also figured out some tricks and knew that as long as it can be converted into the circular rotation of the machine, it would definitely be able to use the benefits of the water wheel.

So this batch of spinning machines was just invested this autumn and was not much made. Spinning is as fast as silk reels. Shu is wet, and there are not many places where white squids can be planted, and the yield is not high, so it is enough. In this way, I still find a villager who grows cotton from the dry land area of ​​Brazil, organized by the State Central Army to buy it, and transport it by ship for hundreds of miles."

After hearing this, Li Su also saw the scene in front of him, and his first reaction was quite awe-inspiring.

A woman can improve the spinning machine based on the hydraulic wire reel truck invented by her predecessors according to her younger brother's instructions. Although the machine in front of her is still very backward, it can only be regarded as a rough prototype and has not fully explored the efficiency of spinning, which is at least an improvement.

There should be no "Jenny spinning machine" in this world in the future, but a "Zhuge Zhi spinning machine".

Perhaps women themselves have talent for textile tailoring, isn’t Huang Daopo, who has improved cotton looms in history, also a woman?

What Zhuge Zhi has done so far has not improved the cotton weaving process. She only improved the cotton spinning production process.

However, when weaving, as long as the design advantages of Zhuge Liang's crossbow brocade weaving machine are directly used, and the width of the weaving cloth is increased to five feet. Even if other technologies are not improved, it can still be two or three times higher than the production efficiency of the people under the rule of other princes. If it is not improved, it will be temporarily enough (calculated based on the production time required for the finished product per unit area).

Li Su was in a daze when he looked at the hydraulic spinning wheel, thinking of improvements in his mind.

He doesn't know much about technology, but he has common sense in life after all. Even based on the common sense learned from Douyin short videos that show off craftsmanship in various industries in later generations, he can still judge the quality of a thing.

Seeing that he didn't speak, Zhuge Zhi was afraid that the atmosphere would be awkward, so she asked him to comment: "What do you think? If it is promoted, can you afford the 'patent'?"

Li Su came back to his senses and commented: "If it can be promoted, it is natural to give a patent. However, if others need to cooperate with you and improve, it should be shared with other people who have contributed. We should reward every technician who has contributed to the prosperity of the people and the strengthening of the country. If you make good things, you should naturally reward them. If you make progress on your basis, you should also reward them."

Zhuge Zhi smiled and said, "Can you tell me how to improve it at a glance?"

Li Su: "If you don't talk about the many, the spinning machine only has as many thread heads as the wire reeling machine, which is definitely a huge waste. The working action of the wire reeling truck is to "pull" and to drive a larger wire reeling wheel, and to use more force. The working action of the spinning wheel is to "rumble" and just drive a spindle with a much smaller diameter, and use very little force.

Even if I take a look, I know that you are wasting great hydraulic power now. If you optimize it properly, you can easily do it with five times or even ten times the spindle spindle of a wire reel truck. And even ten times the spindle of a wire reel wheel, the speed of yarn output will not exceed five times the speed of reeling and thread reeling. Who makes the wire reel pull faster?

Moreover, this time the spinning machine was temporarily modified from the wire reeling machine. The front-end water truck is shared, and the output power is too wasteful, which is understandable. If you specialize in the writing machine water truck, you can reduce the water wheel a little, and the spacing between the water truck and the water truck will also be shortened, so that more water trucks can be deployed by the river, and the power of each water wheel to drag the spindle will not be wasted too much."

This is easy to think of, because it was written in history textbooks that after the appearance of Jenny's spinning machine, there are 16 spindles and 32 spindles, and 80 spindles in the later stage, so where is it?

Moreover, hydraulic machines can actually be made larger than steam engines, because the power output of hydraulic machines is not small. The only difference is that the hydraulic machines are not flexible in deployment and cannot be promoted in areas where there are no excellent water conservancy facilities and unstable water flow energy. The reason why Shu can be done is because Shu has Dujiangyan and Leshanyan made by Li Su.

Faced with Li Su's understatement of "accusations", Zhuge Zhi was of course very angry. The main reason was that she felt that Li Su's comment was too easy. Isn't this disrespect for the fruits of other people's labor and intellectual achievements? It took me half a year to figure it out. I took me a look and said something, and I couldn't stand it emotionally.

Zhuge Zhi is a woman after all. As long as you reason with her, she will easily get furious if she doesn’t work well enough. She immediately sneered with her waist:

"I have such a good eye-catching attitude. I can see the shortcomings of this spinning machine at a glance. Unfortunately, I didn't look carefully and practiced it myself. Do you know that I originally had a way to add spindles to more, but why can't it?

The hydraulic wire reel truck has been running for three or four years, and there are only so many reels. Do you think I haven't tried to add it again? I'll improve the efficiency a little more? It's because the female silk reeling worker is too late to peel the cocoon and the wire reeling worker! Even if two or three female workers look at a water truck reeling machine, the two or three female workers are busy peeling the cocoon and connecting the wire, it can only be so fast.

The same is true for the spinning machine. I am now rubbing cotton and cotton to check the seeds to prevent defects. I am too busy to add more spindles, and then there will be seed yarn and broken veils. The defective products will be at least many times better than now. When I take them to weave cloth later, I will have to rub and weave them by myself when I encounter broken veils, which is much more troublesome. Fortunately, I am still producing and selling them by myself. If the people in the future also weave cotton, the yarn will be taken out, and it will be dumped with their own signature!"

Zhuge Zhi was also feeling aggrieved and said a lot of twists and turns in one breath, showing off all the difficulties that laymen can't understand. After all, the brothers at home didn't care about these strange tricks and tricks. Sometimes she worked hard for several months to improve a little, and said excitedly to Zhuge Jin. Zhuge Jin didn't understand, thinking, "Isn't that a solution just by doing it? I'll even ask for credit and reward for this little thing."

This made Zhuge Zhi very unhappy. She cursed her brother for many times. Only if her younger brother Zhuge Liang was there, she might be able to understand her difficulties and contributions. After all, Zhuge Liang is more expert than her.

After showing off, she felt much more comfortable: You laymen, now you finally know how difficult it is! Even if you can't understand, at least you know that this thing should be very powerful.

Li Su did listen humbly, admitting that Zhuge Zhi's exploration and discovery difficulties were very valuable, but he quickly combined his basic life knowledge and said:

"Cotton floe removal is indeed more complicated than cocoon stripping and silk threading, but this is not the reason why you reduce the spindle density and waste the kinetic energy of water. This shows that you are not fine enough in the spinning process.

The spinning speed should never be restricted by slow other links. Otherwise, if the thread you spin is directly onto the loom, is it that the weaving machine will be too slow to weave, and how slow you spin? It turns out that it is not. You can spin it for five people and ten people to weave it.

What you should do now is to use the white stacked flowers to spin the links before spinning, and then get on the car. For example, if the cotton is not elastic enough, the seeds will remain. For example, before you get on the spinning wheel, you did not comb the fibers and stretch them out, and then get on the car.

Don’t be bound by habits. Wire woven fabrics only have two production links: silk reel and brocade. It does not mean that cotton weaving can only have two production links, nor does it mean that you have to force the elastic combing cotton spinning into the link that is benchmarked with 'swire'."

After hearing these high-minded words, Zhuge Zhi instantly felt that although General Right did not understand the technical details, his words were indeed very philosophical and high-minded.

The reason why she made spinning so cumbersome was indeed bound by habits and experience, and formed a "technical bias", because he felt that the task of the silk reeling factory was to provide finished raw silk that customers could use to weave brocade directly. The spinning factory should also provide finished yarn that can weave cotton for customers.

But after emancipating the mind, I found that it could be further subdivided here, and farmers could sell the original cotton to a cotton-plated cotton mill, and then the cotton-plated cotton was smooth and then the spinning mill was given.

No one stipulates that the supply chain cannot be subdivided, and suppliers cannot have upstream suppliers.

Moreover, this upstream supplier can be opened by Zhuge’s own.
