After the Liu brothers left, the father and son walked around the garden for a while.

Zhu Ming said suddenly: "I plan to be like Sichuan, first in Gyeonggi, Henan, and Guanzhong, and completely abolish the Xiangjun system." The patrol inspection and post delivery functions are retained, and these two aspects have their own attributions, and they are no longer subordinate to the special box army establishment. In addition, it is necessary to retain the Tsunade Army. ”

"Sichuan has not suffered too many natural and man-made disasters, and a large number of miscellaneous soldiers have been resettled," Zhu Guoxiang asked, "Have you figured out how to resettle these three places you mentioned?" ”

Zhu Ming said: "The nearest land is divided and cultivated, and part of it is transferred to the official service. In the future, the law of exemption from military service will be implemented, and this should be completed in conjunction with the apportionment of land to the acre. Therefore, the abolition of the box army is matched with the inventory of acres and the spread of acres into acres, and if they are not mixed together, there will definitely be chaos. ”

Zhu Guoxiang nodded and said, "Give a set of regulations out, and I'll let the magistrate implement it." It was first piloted in Gyeonggi and Henan, and continued to fill in loopholes and fine-tune policies, and then expanded to Guanzhong and Huainan. ”

Zhu Ming said: "Once the south is pacified, the two Huai are the top priority of the reform of the Xiang army. If it can be changed there, there will be no problem in the whole country. ”

The Xiang army in the Song Dynasty was not only used to fight, they had all kinds of duties.

First, transport supplies.

Whether it is to carry grain and grass, or to carry various programs of the imperial court, the first consideration is to let the box army do it, and the people will be recruited when the manpower is not even.

Second, build water conservancy, repair the city, build the palace, and build the imperial tomb.

For this kind of government project, priority is also given to the dispatch of the van army, and then the people are requisitioned and supplemented according to the amount of work.

Third, the reclamation of tuntian.

Frontiers or a few internal areas, if there is a need for tuntian, also throw the box army over.

Fourth, for officials to serve.

Officials are ordered to go out of Beijing, the superintendent inspects the place, the officials go to work for long distances, and even the officials move to change houses, they can directly let the Xiang army serve as bodyguards and do chores.

Even if the official's parents are sick and the official has a heavy responsibility and cannot go home, he can apply for the Xiang Army to help deal with the funeral, and in principle, the allocated Xiang Army is within 100. or if the official himself dies of illness and sends a box army to escort the body all the way home, in principle, no more than 30 people can be transferred to the box army.

Or, the official called the box army to serve as a miscellaneous officer, or even let the box army be a subordinate to him for free.

Even the lowest-ranking deputy capital head can serve as a van army.

At the Zhizhou level, two hundred van troops can be served.

The border generals of the Song Dynasty even dispatched the Xiang army to burn charcoal on a large scale, without giving any subsidies, which was equivalent to long-term hard labor, but the charcoal burned was sold by the generals to make money.

This practice was once very popular, causing a large number of charcoal-burning Xiang troops to be unbearable, and fled directly into the mountains to gather as bandits.

Due to the fact that there were too many charcoal-burning troops who fled, the Northern Song Dynasty court had to order a ban and explicitly prohibit the box army from engaging in charcoal-burning work.

There are many other messy things, and the box army that can be a patrol soldier and a handing shop soldier is already a very lucky person in the box army. They even have to accept tasks such as logging, shipbuilding, winemaking, mining, producing weapons, passing documents, and palace chores.

Do you think that the court of the Great Song Dynasty was kind-hearted, and as soon as something happened, the homeless people and anti-thieves were organized into a box army, and so many box troops in the country were raised by the government for nothing?

Zhang Ruyu, an official of the Southern Song Dynasty, directly summed it up in eight words: The Song Dynasty has the world, and the army is in service.

It is precisely because the business scope of the Xiang Army is too wide and the number of people involved is too large that it has been difficult for Zhu Ming to carry out comprehensive reform.

In Sichuan, a large number of miscellaneous soldiers were resettled and resettled, and even relocated to Nanyang and Xiangyang, resulting in a shortage of manpower in the government in many cases. For slightly larger public projects, all the people must be recruited, which is a great test of the local officials' ability to govern and coordinate, but the prefectures and counties in Sichuan are still overhauling water conservancy.

The deep-seated area of the reform of the Xiangjun is in the two Huai, and to put it bluntly, it is a problem of program movement.

If the two Huai Gang armies are abolished, should we form another two Huai Cao armies?

Zhu Ming's idea was that the Gang Army would be separated from the sequence of the Xiang Army, and the Gang Army would be organized into a system with the delivery and delivery soldiers, which would be specially responsible for mail and transportation business, and would be placed under the jurisdiction of the Ministry of War as a whole. This is a kind of compensation and balance given to the Ministry of War by the Privy Council and the Generalissimo's Office, which have taken away too much of the power of the Ministry of War.

Today, Zhu Ming took Zhang Jinping and Zheng Yuanyi and returned to the direction of the East Palace in a carriage.

When he was almost at the place, he stopped, climbed the city on a whim, and walked through the walls of the imperial city for a while.

The northwestern part of the city is a real nuisance, it is almost deserted, a large number of pavilions and pavilions, during the defense of the city, chopped for firewood, and stones have been removed to make falling stones.

A pile of large and small stones were piled up on the city wall, and the well-preserved high-grade Taihu stone was auctioned off to the wealthy by the government. And the stones that have been broken are carried by the people at will, or they are wholesaled to the builders.

Today's Genyue, overgrown with weeds and no one takes care of rare flowers and trees, stands so abruptly in the northeast corner of the city.

Maybe we can clean it up a little bit and repair a few more pavilions for the people of Tokyo to enjoy on a daily basis.

Zhu Ming had an idea and thought of the Astronomical Academy.

An observatory can be built on the top of the mountain of Genyue, and even if the capital is moved in the future, the observatory here does not need to be moved, and it is compared with the astronomical observation data of Luoyang.

In the Song Dynasty, those astronomical officials often falsified, and the emperor had to set up the Hanlin Astronomical Academy. Originally, it was intended for Si Tianjian and the Academy of Astronomy to urge each other, but as a result, the old and new astronomical departments worked together to falsify and fabricate observation data to fool the emperor.

Now, the new dynasty of the Ming Dynasty has merged the Si Tianjian and the Astronomical Academy, and eliminated two-thirds of the indiscriminate people, and the name of the new institution is "Astronomical Academy".

Zhu Ming left the city wall and planned to go to the astronomical institute to have a look.

Zheng Yuanyi was not interested in that thing, but Zhang Jinping was very interested. She has many relatives who like to engage in technology, not only did her ancestors improve the wet copper smelting process, but her cousin also invented the tangram a few years ago.

The prince came in person, and the chickens and dogs jumped up and down the Astronomical Academy.

Huang Shang, the envoy of the hospital, rushed to greet him when he heard the news, and he was a little resentful in his enthusiasm. This old champion of the former dynasty was first thrown by Song Huizong to compile the Taoist scriptures, and now he was brought by Zhu Ming to manage astronomy, but he has always wanted to be a political official.

"How's the pendulum clock doing?" Zhu Ming asked casually.

Huang Shang said: "It's almost done." ”

Zhu Ming nodded: "Go and see." ”

The Northern Song Dynasty's water transport instrument and the discussion of manufacturing Jiheng are still placed in the yamen of the Astronomical Academy. These two are astronomical measuring devices, and the clock properties are incidental.

After the father and son entered Tokyo, they soon merged and streamlined the astronomical organization, and asked Huang Shang to lead people to develop mechanical clocks.

The chief engineer of the R&D team is the king of the Taoist who came up with the "discussion and manufacturing of the Jiheng Institute". Zhu Guoxiang brought a few Yangzhou scholars who like to study physics, and they also joined this scientific team. Some craftsmen were seconded from the Ministry of Works, and the whole team was about 30 people in total.

The overall idea was provided by Zhu Ming.

There is no need for a clockwork mechanism, it is powered by a heavy hammer and punctual with a single pendulum.

After the invention of this pendulum clock by Galileo, it had no major drawbacks other than that it was too large and inconvenient to move. Even in the age of the Internet, there are still many "retro" people who place this kind of clock at home to keep time, and take videos and post them on the Internet to pretend to be forced.

But Zhu Ming has only seen the appearance and knows the basic working principle, and he doesn't understand the specific internal structure at all.

Daoist Wang was squatting in the room to do research, and when he learned that Zhu Ming was coming, he hurriedly led the team to greet him: "Meet the prince, meet the princess!" ”

Zhu Ming and Yan Yuese smiled in return, compared to other officials, the smile at this time was the most sincere: "No formality, how is the development?" ”

Wang Taoist said: "It is almost done, and some small places need to be changed." ”

Although the Song Dynasty's water transport instrument and Galileo's heavy hammer pendulum clock needed to be adjusted with an escapement. But the two escapements are very different in design, and Wang Daoist is equivalent to having to redesign them.

There was more than one hammer clock, each of which was more than one person high, and Daoist Wang asked his assistants to disassemble all the shells.

Pointing to one of them, Wang explained in detail: "The hammer drives the ratchet, and the teeth push away the pawls of the pivot (axis), causing the pivot to turn at an angle. The pawls under the pivot are turned just to block the teeth below. The ratchet continues to rotate and pushes it away again, and the pivot balance turns back to its original position, thus completing a swing ......"

Explanation and demonstration, Zhu Ming understood at a glance.

Daoist Wang continued: "This device that swings horizontally above is called Tianquan, and it was originally used to adjust the speed and slowness. The minister was really embarrassed, and did not use the single pendulum as the prince said, but although this horizontal pendulum can also be adjusted, the daily drip and sundial check but the error is very large. ”

Zhu Ming smiled and didn't accuse.

The isochronism of the single pendulum, this thing is simple to say, but the detailed explanation is extremely complicated, and it is normal for Daoist Wang not to follow what Zhu Ming said.

And according to the hammer idea provided by Zhu Ming, Daoist Wang was able to study the pendulum clock, which was already very capable.

Wang Daoist pointed to the single pendulum clock next to him: "Later, the minister made a few large single pendulums and stared at the drip test for three days. The period of the pendulum is indeed not related to the swing amplitude, but only to the length of the cycloid. The pivot device that specifically adjusts the speed is the most punctual in the end (the point of action that blocks the pendulum rope in the escapement), and it is still slowly and repeatedly compared. ”

"Using a sundial to test, how big is the error now?" Zhu Ming asked.

Daoist Wang replied: "The error of one month is about two quarters of an hour. ”

Zhu Ming nodded approvingly: "It's already extremely accurate." ”

Wang Taoist said: "It can be improved." ”

The sundials of ancient states and counties were not made very finely, and the error of one day could reach fifteen minutes.

However, the astronomical department of the central court used sundials that were extremely accurate, with an error of no more than 20 seconds per day.

In the Song Dynasty, there was already a saying about the hour, and Zhu Ming said: "The hour follows the old practice, and another hour can be divided into sixty parts, each of which is one minute." You make another minute hand to count the minutes. ”

Daoist Wang opened his mouth wide, and finally lowered his head and said, "Yes!" ”

Adding a minute hand is not as simple as it sounds.

The leader opens his mouth, and the subordinate runs and breaks his leg.

When Daoist Wang made the minute hand system, it was time for him to make the time system.
