"It used to be a blacksmith, but now it's much easier." Zhu Dalang said.

He opened a blacksmith shop in the east of Luoyang City, using charcoal to smel iron and making utensils. As for why we don’t need to smelite coal, we have something called transportation cost in the world. Using smelting coal is not cost-effective, and coal in other places is of poor quality and cannot be used.

He is now making some metal components on the sluice. Such simple things are usually done by his apprentices, and he just watched them from the side.

Because of the huge demand brought by Luoyang's urban construction, he recruited several new apprentices and carefully taught them, so it is much easier to be a blacksmith now than before.

There were people coming and going outside the door, and it was extremely noisy. Zhu Dalang liked this noisy feeling very much. He walked into the yard, carefully picked up a wooden ruler and looked at it.

"Zhu Da, you thick, now you finally know the benefits of a ruler?" A loud voice sounded outside the courtyard gate. Soon, a young official wearing a green robe walked in.

"The official is finally here." Zhu Da showed a flattering smile and immediately ordered the helper to carry a few baskets, filled with metal components.

The green robe official took the wooden ruler from Zhu Da's hand and measured it carefully.

The state dynasty had regulations: "Anything that is based on the northern millet, the broad range of millet is divided into ten inches, ten inches is a rule, one foot and two inches is a large rule, and ten feet is a meter."

To be honest, this is not very accurate. The sizes of all dynasties also have the same length, but in fact it seems different and very messy.

When building the palace, Shao Shude made a request to strictly follow the size of the drawings. In order to determine the size, he even got out of the way and stepped forward with his left foot. He was not sure how long it was, but it was estimated that it would not be too big if it was about one meter.

He stipulated that this half step was ten feet, and then borrowed personnel from Chang'an Shaofu and made a ruler, called the construction ruler.

Next he made a request, using a ruler to make a drawing to give this ruler ten equal points.

This stumped the students under Master Mani. Master Mani even read the copied geometry books he brought from Dashi, first learned how to divide the three equal parts, and then after a period of research, he finally figured out the ten equal parts method.

Dividing, cubic, sprint, zhang, Shao Shude requires that it must be accurate, and this can only be achieved using mathematical methods.

With accurate measurement, it is helpful for production and construction. If the production model of standardized assembly line does not have accurate measurements, the more the process goes out, the greater the error.

This has not yet reached the time of the industrial revolution in the later years. In history, the British invented the marking machine that can accurately mark the scale, which was simply used as a weapon to guard against the country. This is also an important reason why the specifications of British industrial products in the steam engine era were relatively unified.

There was no clamping machine at this time, and it was very difficult for Shaofu to make a scale. Most of the handicrafts in the country were made at will, with products of different sizes and no interoperability.

Shao Shude didn't care much. He just wanted to greatly promote the progress of mathematics through the creation of Luoyang Palace and use the concept of standardized production.

Mathematics is the basis of large-scale standardized industrial production, and there is no doubt that Shao Shude once joked that all the students of Master Mani passed his qualification assessment and could go out to make standards and sell them for money. They sold these standardized standards to states across the country, so that every craftsman had a standardized standard.

Without standard machines, how to standardize production? Popularizing, scaled and cabbage-making is the top priority. But since ancient times, standard machines have been almost "sacred objects". No one in every state must have one, and the scale is also very inaccurate. There is no problem when making uncomplexing parts, and it is troublesome when it comes to complex machines.

This is the problem.

"Okay, the craftsmanship is pretty good." The green-robed official smiled and said, "I marked the measure of this ruler. Alas, I have been struggling for a long time."

"The things used on the gate are actually not so accurate." Zhu Da muttered and asked again: "Officials, have you pulled all these things over?"

"Pull it over." The green robe official nodded and said, "Let's go now."

The two found a donkey cart, took the iron building to the east of the city, and parked next to a dug reservoir.

Someone is installing gates on the reservoir. The principle of the gate is similar to the suspension bridge outside the city gate. Use a gate or winch to pull it up or lower it.

This reservoir stores static sewage. There is a gate installed next to it, and the area inside is full of sewage. There is also a reservoir that has been completely discharged, and the bottom of the reservoir is filled with thick and touching smell and suspiciously "silt". After the silt is exposed to the sun for a period of time, people will be sent to the fat fields in Guanzhuang.

Some people in Luoyang have already lived in it. The domestic wastewater generated in their yard flows into these sewage pools through crypts. After standing, the water is discharged into Luoshui, and the sediment is regularly dredged and excavated.

At present, only a small number of urban areas have been renovated. In the future, the entire Luoyang will be like this. It is conceivable that the project volume is extremely large and may last for many years.

After the green robe official handed over the handover with the person, he hurried away.

King Xia Youling opened a mathematics museum in Luoyang this year and recruited students. Those who studied in the previous few years will stay on the spot, acting as doctoral students, assistant teachers, and lecture directly, and continue to cultivate more mathematics talents.

According to King Xia, mathematics can train "logical thinking", which is something that most people lack. Without "logical thinking", there is only "technology", and without "science", they are all fresh words, and I have never heard of it before.

By the way, in addition to the books such as "Nine Chapters", "Island", "Sunzi", "Five Caos", "Zhang Qiujian", and "Xiahou Yang" stipulated by the state, Master Mani is also compiling a masterpiece "Mathematics and Geometry". King Xia promised that if the book is completed this year, he will award him the "Xia King Award" and be appointed as a scattered official of the senior official.

Shao Shude rushed back to Bianzhou quickly, and the first thing he did was to find Zhang Hui.

The second thing is to call the two heroines of Zhu Quanzhong’s “daughter-in-law” together.

Then he calmly called Ma Wanpeng who had been waiting for many days and started to do the important business.

Ma Wanpeng is a very famous shipbuilder in Lingzhou, but his true level is second to none in the northwest, very average in the Central Plains, and worse in the south.

However, there are not many capable talents at the moment, so I can only use it. I hope he can make progress.

"Why do I see that the navy ships are mostly flat bottoms?" Shao Shude asked.

"The water is shallow and there is a lot of mud and sand, which is not easy to get stuck, making it easy to sit on the sand and is stable. Northerners are familiar with the nature of water, so this is the only way." Ma Wanpeng replied.

"But this ship cannot get out of the sea." Shao Shude frowned.

In fact, he said it tactfully. Not to mention that you can’t go out to sea, you will have big problems when going to big rivers with bigger storms.

The shipbuilding technology in the north ultimately comes from the canal ships, which is too poor. There are few talents and high costs, and there are very few soldiers suitable for the navy, and the overall quality is also relatively low.

When the floating bridges in Heyang Sancheng were first built, the ships used were made of large wood in Hongzhou, Jiangxi. There were few materials suitable for shipbuilding in the north, and they were very expensive, and fir was not a good ship material.

"Yes." Ma Wanpeng admitted: "But the plunger can also go out to sea. Mizhou and Dengzhou seaports, all the plungers are plungers."

"Can you build a pointed-bottomed boat?" Shao Shude gestured with his hand and said, "The pointed-bottomed sailing boat that can navigate has three masts, divided into front masts, middle masts, and rear masts. The sail can be lifted and lowered, rotated the sail truss, and adjusted the windward surface. The sail surface size can also be adjusted."

Shao Shude didn't know what to say about some nouns, maybe there was no such concept at this time, so he could only speak according to his own ideas, and the result was that Ma Wanpeng was confused.

"Call me a painter to understand people's words." Shao Shude shouted to the door.

Li Yixian ran to pass the order.

After a while, the painter ran over panting and said, "See the King."

Shao Shude stood up and returned the greeting, saying, "Sit down and draw a boat for me."

The painter was stunned.

If you ask me to draw people, you can draw flowers, birds, fish and insects, you can draw ordinary fishing boats, but the requirements of King Xia are obviously not that simple.

"You can just draw it, I won't blame you." Shao Shude said warmly.

"As for the order." The painter bowed his hand, sat down and spread out the paper and pen, and prepared the ink.

Shao Shude carefully described his request. The painter was sweating profusely and reluctantly painted, and Ma Wanpeng gave a guide.

While trying hard to recall, Shao Shude added: "The front mast has three sails on the middle mast. The upper sail and the top sail can be lifted and lowered. Yes, lifted and lowered with cables. The sail is horizontal. Do you understand the horizontal sail?"

"The backmast is equipped with a spinnaker. What? What is a triangle? Uh..."

"There must be a presprit on the bow and canvas are placed on it."

"Yes, the stern building is larger and higher, it can be a second or third floor, and the forecastle is smaller."

"I almost forgot. Add a mast building between the lower sails of each mast to allow the sailor to enter and collect the sails. Another building on the mast can allow the sailor to climb up and look up from a distance."

"A mast like this should be very strong? Of course! Not only masts but also keels, it is best to use mahogany. If it really doesn't work, use other substitutes."

"Canvas? Of course it's soft sail, just linen."

Shao Shude's request made the painter rush, and Ma Wanpeng almost suffered a heart attack when he heard it.

To be honest, this is a completely different design concept, another system, which looks like it is prepared for sailing the ocean, rather than running offshore.

"King, if you want to build such a ship, you may have to go to Dengzhou to find a solution. Someone is not talented and ashamed." Ma Wanpeng said helplessly.

"It's okay, you can be an official." Shao Shude smiled and said, "I need an expert to help me control the overall situation, and you don't need to actually build a ship. When I defeat the King's Normal School, this matter will be started. I won't urge you, but you must know the severity and find a way to get one out first. Even if there are many problems, build it first to test the sailing, and then slowly improve it."

"Why do you want to do maritime trade?" Ma Wanpeng asked.
