The Ming Dynasty started with saving the eldest grandson

Chapter 166: Eliminate the troubles of the grassland forever? (Additional update for [-] monthly tickets)

Yishui and Luoshui are two rivers flowing from west to east and are also important tributaries of the Yellow River.

When it is about to reach the Yellow River, the two rivers merge into one, the Yiluo River, and then merge into the Yellow River.

The old city of Luoyang is still dozens of miles away from the intersection of the two rivers.

Naturally, the new capital cannot be placed in the old city. The amount of work would be too great, and demolition alone would take several months.

After conducting on-site inspections and soliciting opinions from many parties, the new city was placed closer to the intersection of the two rivers.

But this also means that there is not enough land in the angle.

"According to Jing Ke's suggestion, the new city will be built to accommodate one million people."

"We also need to reserve enough spacious streets and loose living space. The area is too large."

"The land between the two rivers is not wide enough."

"...In order to solve this problem, the officials who served as supervisors conducted on-site surveys and proposed a plan. The new capital will be across the Yishui River."

"The main body of the new capital and the imperial city are between the two rivers, and a quarter is to the north of Yishui."

"There are four advantages to doing this. First, it is easier to obtain water from Yishui."

"Secondly, the transportation is convenient. Water transport ships can directly enter the outer city from Yishui."

"Thirdly, if the city needs to be expanded in the future, there is still a large area of ​​land in the north of the city that can be used."

"Fourth, the quarter of the city north of Yishui can be used as a commercial area."

The mixture of people in the commercial area is difficult to manage, and Yishui is a natural isolation zone.

Once there is trouble there, all we need to do is blockade Yishui to cut off its connection with the main city.

Of course, this does not mean that business cannot be done in the main urban area, but the scale is different.

The part north of Yishui is a large commercial area.

The businesses in the main urban area are small and not concentrated.

The Royal Palace is in the very center of the main city.

"A capital city that accommodates millions of people is simply too large."

"To facilitate management, I plan to draw a tic-tac-toe with the palace as the center."

"The palace is in the center of the well, and the eight surrounding areas are divided into eight squares."

"The eight squares are separated by high walls. During the day, the gates of the squares are wide open, allowing everyone to come in and out."

"There is a curfew at night, or in case of emergency, we close the doors and cut off communication with each other."

At certain times, these walls can also serve a defensive purpose.

These squares are different from those in Chang'an City of the Tang Dynasty.

The squares of Chang'an City in the Tang Dynasty were relatively small, and the huge Chang'an City was divided into a total of [-] squares.

The advantage is that it is easy to manage, but the disadvantage is that it is too closed and is not conducive to communication.

Since the Song Dynasty, there were no longer any buildings, and people lived within the same city wall.

This is also related to the developed commerce of the Song Dynasty.

Yingtian City also has a unit called a square, but it is more similar to the city area in the previous life. It is completely open and has no city walls to block it.

Although the workshop created by Zhu Biao is separated by high walls, the area is too large.

The scale of the new capital city is larger than that of Chang'an City of Tang Dynasty. Only the main part is almost the same as Chang'an City of Tang Dynasty.

Such a large area is divided into nine parts, and the individual area can be said to be very huge.

There is no problem at all if there are over [-] people living there.

Therefore, although it is also a workshop, it is not closed.

Zhu Yuanzhang was very satisfied with this design: "The commercial area is separated by Yishui, and the main city is managed separately."

"Okay, okay, this method is very good. Your design, Biao'er, is even better than we thought."

Chen Jingke naturally has no objection. In the absence of the 'Sky Eye System', partitioning is indeed the simplest and most practical management method.

Otherwise, thinking about how much chaos would be caused by so many people crowded into a city wall makes one's scalp numb.

Zhu Xiongying was even more excited, this was his future new home.

I wish I could have built it overnight.

In addition to these, there are four artificial canals running through the city to facilitate the people to use water.

The sewer project that Chen Jingke was more concerned about was also designed.

The sewage is discharged directly outside the city, so there is no need to worry about pooping everywhere and turning the new capital into a shit city.

In fact, his worries are a bit unnecessary. Since the technology of retting has matured, feces and urine have become treasures.

This is still a very popular business, and most people can't get involved.

Taking Yingtian City as an example, it is said that the entire city's excrement is monopolized by a few large households with mysterious backgrounds.

They will send people to go door to door to help people clean up this stuff for free, and then transport it out of the city for retting.

The fertilizer can be used for one's own use, or it can be sold to other large farmers, which can be regarded as a huge profit.

But even so, sewers are an important facility.

With it or without it, it's completely different.

Next Zhu Biao introduced the Imperial City.

It has to be said that the Nanjing Forbidden City designed by Zhu Yuanzhang in his previous life influenced the palace architecture of the Ming and Qing dynasties in later generations.

In this life, Zhu Biao could not get rid of Lao Zhu's influence.

Luoyang Palace is generally similar to Yingtian Imperial City, but the details are slightly different.

Regarding the design of the imperial city, Chen Jingke had little to do. He only proposed one idea.

Earthworm.

It's also a heating pipe.

The winter in the north is very cold, and life would be difficult without this thing.

In ancient times, there were no pressure pumps, so there was no way to create a heating system that covered the entire imperial city.

But the problem is not big, they can be designed separately, and each palace has an independent heating system.

The construction of the new capital not only included the imperial city itself, but also included the surrounding passes.

There are natural barriers around Luoyang, but due to its declining status, most of these passes have been abandoned.

Now it has to be completely rebuilt and strengthened on the original basis.

There are also granaries, as Kyoto must have enough food stored.

The site selection and construction of granary is also very important.

Zhu Biao just introduced it, which took nearly an hour.

You can imagine how many links are involved.

On the other hand, the design of this new capital city is perfect.

Zhu Yuanzhang was very satisfied and immediately decided to start construction.

At this moment, Chen Jingke came up with a 'black technology'.

Concrete, commonly known as cement.

Although he had known for a long time that he still had a treasure in his hand, Zhu Yuanzhang could not help but be shocked when he heard about cement:

"You mean, you can grind clay, iron ore, limestone, and gypsum into powder, mix them together, and then add water to solidify them into stone?"

Chen Jingke can completely understand his mood. This thing can be called a weapon of war.

Building a strong city on flat ground can directly change the war situation.

"You can also use fragments of porcelain, pottery, or slag. As long as the proportions are right, add water and stir to solidify into stone."

"If you add the right amount of sand and gravel, the effect will be better."

Zhu Yuanzhang didn't say anything. He immediately found someone to get what he needed and did the experiment himself in the palace.

A few days later, Zhu Yuanzhang was very excited when he looked at the cement lumps that had solidified into a ball.

He drew out his sword and struck hard, causing debris to fly everywhere.

"It's not as hard as a rock, but it's not too hard either."

"Okay, this concrete is really a weapon for the country."

Zhu Biao was also very happy: "With this thing, the cost of building a new capital can be reduced by several percent, and the speed can be accelerated several times."

"Jing Ke has made another great contribution." Zhu Yuanzhang nodded, and then said dissatisfied: "Don't praise him, this kid has a lot of good things hidden, and he is unwilling to take them out."

"To return the favor, we all want to beat him up."

Chen Jingke chuckled and did not take these words seriously.

Lao Zhu is a very arrogant person sometimes. He obviously wants to praise someone but insists on saying the opposite.

"Concrete has poor tensile and bending resistance. Bamboo bars can be added to it during pouring to increase toughness."

The effect of bamboo tendons is also very good.

In the previous life, there was a building made of bamboo as ribs, which survived for hundreds of years without falling down.

In the end, it was demolished because it was too old.

The bamboo strips exposed after being removed still maintain sufficient toughness.

The buildings of the Ming Dynasty were generally not high, and the city walls were only a little over ten meters, so there was no problem using bamboo tendons.

At this time, Zhu Xiongying circled around the cement bump several times, then touched his chin and said:

"Use this thing to build a few cities on the grassland, and the people of Beiyuan will not cry to death."

Zhu Yuanzhang laughed and said: "Haha, he is indeed our good grandson, and he wants to be with us."

"Now the Beiyuan people have learned to be smart. When our army attacks, they move away to avoid fighting."

"If the army goes too deep, they will send troops to attack the grain roads."

"When our army retreats, they will come back with their cattle and sheep to continue their lives."

"The final result is that we often waste manpower and material resources but achieve nothing."

"It's different when we have a city. Our army can be nailed to the place like nails."

"We want to see how they plan to break this game."

Zhu Biao also agreed, saying: "With this method, there are natural dangers everywhere."

"It's just a pity that there is no way to keep the concrete production method secret and it is easy for the enemy to obtain it."

Chen Jingke smiled and said: "Your Highness, there is no need to worry. Cement is just a dead thing. It can play its greatest role in the hands of those who know how to use it."

"Besides, our army of the Ming Dynasty is all over the world. I don't know how many strong cities and fortresses I have captured. What will happen if I have a few more."

Zhu Biao laughed and said: "That's true, but I'm a little stingy."

Zhu Yuanzhang smiled and said: "Now our only enemy of Ming Dynasty is Bei Yuan."

"It's useless even if they get the production method, there are so many materials that can't be found on the grassland."

"Besides, we really want them to build the city."

"After building the city, they reluctantly left. They could only stay and fight us head-on."

"This is actually easier to handle."

When the Central Plains dynasties fought against the grassland nomads, the biggest problem was not that they couldn't defeat them, but that they couldn't find the people there.

You took the initiative to attack, and others scattered to avoid him.

If you retreat, people will gather to attack you.

Chen Jingke thought for a while and said, "Your Majesty, with the cement city, I have a good way to deal with the Beiyuan people."

Zhu Yuanzhang immediately became energetic and asked: "What can we do?"

Zhu Biao and Zhu Xiongying also gathered around curiously.

Chen Jingke picked up a wooden stick and started drawing on the ground:
  "Divide the grassland into grids and allow the submitted Beiyuan tribe to live in these grids. They are not allowed to leave without permission."

"The imperial court built cities near rivers and sent officials to manage these tribes nearby."

"You can also migrate Han people to live around the city and cultivate farmland..."

Zhu Yuanzhang thought: "The method is good, but it also gives the Beiyuan tribe room to recuperate."

"Once they get bigger, there's a danger of them uniting and rebelling."

Chen Jingke said: "Your Majesty has thought deeply about it, but it can be solved."

"Split up. The court stipulates a population limit for each tribe. If the number exceeds, it will be split up."

"The people who were demolished were moved to distant places to settle."

"Let them never be able to contact their original tribe for the rest of their lives."

Zhu Xiongying interjected: "They can also be moved to the hinterland of the Ming Dynasty and live together with the Han people."

"Speaking Chinese, writing Chinese characters, wearing Chinese clothes...it won't take many years for them to be assimilated."

Zhu Yuanzhang was overjoyed: "Okay, once the method of grid placement and division is figured out, Bei Yuan will no longer be a disaster."

Zhu Biao thought more and said: "The hidden dangers of the grasslands that have troubled the Central Plains Dynasty for thousands of years may be completely solved in the hands of the Ming Dynasty."

Seeing that this method might be feasible, several people became very excited.

Gather around to discuss more details.

Soon there was a rough plan.

Of course, things won't be that simple.

Building a city in the heart of the enemy will be self-defeating if you are not careful.

There is a lot that needs to be done to be foolproof.

However, these details will naturally be designed and perfected by specialized people.

Finally, Zhu Yuanzhang said: "This method is kept secret for the time being. Do not leak it."

“After this innovation is completed, we can start implementing it.”

Everyone knew the seriousness of the matter and nodded.

Zhu Biao stayed in Yingtian for a few more days, and after understanding the progress of the changes, he left Beijing again for Luoyang.

Originally, he wanted to stay for a while.

The materials are not yet in place, and the land in Luoyang is still being leveled.

It would take some time for the new capital to be officially started, so it would be useless if he went there.

With concrete the situation is different and many materials need to be adjusted.

For example, the demand for glutinous rice has been reduced to a minimum.

In ancient times, in order to ensure the quality of city walls, glutinous rice soup was used as an adhesive.

Needless to say, this thing is really useful.

The disadvantage is that the price is too high.

The yield of glutinous rice is already low, and the amount used to build the city wall is large.

This alone accounts for a large part of the total investment.

The key is that food is precious. If you use more to build the city, the people will eat less.

It is no exaggeration to say that the city wall was built with money.

But now with concrete, glutinous rice can basically be saved.

After Zhu Biao left, Chen Jingke and Zhu Xiongying returned to their usual busy schedule.

Study and handle government affairs during the day, and go home to summarize at night.

After more than a month of hard work, Chen Jingke finally finished checking "Hongwu Suanjing".

There is no problem.

He let out a sigh of relief, finally done.

Then he presented the book to Zhu Yuanzhang.

Zhu Yuanzhang had known about this for a long time, and without saying anything else, he directly ordered five thousand copies to be printed and distributed throughout the world.

Against the backdrop of the political reform, the publication of "Hongwu Suanjing" did not cause much commotion.

After all, it is just an arithmetic book, so it is normal for it not to be taken seriously.

Except for Chen Jingke, no one at this time realizes what this book means in the scientific community.

The calculation of the scriptures officially came to an end, and Chen Jingke felt much more relaxed.

You can devote more energy to studying government affairs.

However, at this moment, something happened that no one expected.

Mao Xiang entered the palace and reported secretly: "I have found evidence that Li Shanchang is an accomplice of Hu Weiyong."
