Annan.

"Soldiers of the Ming Dynasty, how do you feel about it?"

Li Jichen asked with concern.

His eldest son led the army in the field, accompanied by his youngest son Li Hancang, the youngest son's biological mother, who was born as a princess and had the blood of the Annam royal family.

"Elite soldiers."

Hu Shu, the general of Zuo Shengyi's army, said.

"It's just a hand-picked one." Li Hancang said confidently, he thought that it was the Ming Dynasty that wanted to promote the prestige of the country.

When Hu Shot heard the little prince's statement, he did not raise doubts.

Li Jichen frowned and pondered.

As the actual controller of Annan, he is not from the royal family, and he has no advantage compared to his father-in-law.

And the opposition forces in all aspects of Annan can be leveled down by him one by one, which shows his talent.

The connection between Daming and Annam is not small.

Probably the nature of the Han people.

As long as it is a place where you can farm, the attraction to the Han people is very strong, so Annam's past and present life is full of motivation to expand outward.

Only in the Ming Dynasty, because of the clan system established by the Ming Dynasty, a large number of surrounding forces declared themselves vassals to the Ming Dynasty, which caused Annan's unhappiness.

In the eyes of the Annam-Chinese people, these areas are not countries at all, they are just barbarians, and tribes exist.

Champa in the south, Laos, Cambodia, Siam, etc., should all be Annam's sphere of influence, and efforts have been made.

Historically, these areas have also been annexed, such as Champong, which was completely annexed by Annam in the future and disappeared into the long river of history.

Therefore, for the changes in Daming, Li Jichen has heard some news, which has attracted his great attention.

"How are their firearms better than ours?"

"I haven't used it, so I can't know."

Hu Jie shook his head, but said again: "But it looks beautiful, and the fire guns of each of them can't be seen from the naked eye." ”

Li Jichen's face became even more ugly.

Annam is not an uncivilized land, it is a Han Chinese who migrated from the north, and the scholars read the Four Books and the Five Classics, and the same imperial examination system as the scholars in the mainland.

The accent spoken by the local Chinese is the same as that of the local dialect of the Ming Dynasty.

So Annan was very productive.

It has its own development in firearms, both handcuffs and firearms, and has compiled a divine machine gun gunnery, which is no worse than that of the Ming Dynasty.

Daming and Annan learned from each other in firearms, each had its own advantages, and learned from each other's strengths.

Unlike other countries in Southeast Asia, they mainly learned firearms from the Ming Dynasty, and there are not many technologies worth exchanging.

This is also the confidence of Annan to claim hegemony in Southeast Asia.

So between the three words, when I heard that the firearms used by the Ming soldiers were not visible to the naked eye, Li Jichen knew the power of them.

"Let Huang Huiqing deal with the Ming mission."

Li Jichen made a decision.

Huang Huiqing is also a Chinese, the minister of Annam, a person who has a heart for China, and he can appease the mission.

Li Jichen quietly explained a few words to his youngest son.

Everyone is in the same vein, what weaknesses can be grasped, Li Jichen's heart is clear, and the Ming scholars are not greedy?

The delegation sent by Zhu Gaoxu was warmly welcomed.

The most important thing is that the people here are the same as in China, and the officials of Yang Bo and Annan drank and wrote poems, leaving one poem after another.

The poetry level of Annan readers is not low, and even in the current period, in the early Ming Dynasty, it is generally stronger than that of the local readers of the Ming Dynasty.

When the Song Dynasty fell to the country, a small number of remnants went to Goryeo, some of the remnants went to the Wa Kingdom, and most of them poured into Annam.

The old and new Chinese people, united as one, fought hard, repelled the invaders of the Yuan Dynasty three times, and preserved the last pure land of Chinese civilization.

The apprehension before coming disappeared cleanly, made a lot of friends, and came from a large family, these people opened their mouths and closed their mouths to China, which made Yang Bo very happy.

When Yang Bo returned, a large number of Annan officials saw them off, prepared several large carts for them, loaded them with gifts, and sent Annan's soldiers to escort them.

After returning to Guangxi, Yang Bo learned that the king of Gaoyang County was sick and bedridden, and at this time, because of Zhu Gaoxu's illness, people couldn't care about anything else.

In addition, it was already the end of the year, so Yang Bo did not go to the capital until after the beginning of spring, the imperial court sent a doctor, and officials who came to understand the situation in Guangxi and Annan.

Yang Yong, the political envoy of the Zuobu Political Division, came forward and informed him that someone had sent an envoy to Annan, and then Yang Bo was invited over.

Yang Bo told him in detail what he heard in Annan and what he saw, and after the official confirmed it, he hurriedly sent the news back to the capital.

The doctors of Jinzhou had a fierce dispute over the condition of the king of Gaoyang County.

"It is damp and hot dysentery, which should be treated by clearing the intestines and dissolving dampness, regulating qi and blood, and slowing down with peony decoction." A doctor said.

"That's not right."

"The king of Gaoyang County is suffering from epidemic poison and dysentery, so he should clear away heat and detoxify, cool blood and remove accumulation, and add pulsatilla soup and peony medicine soup to deal with emergencies."

Golden State's medical science has advanced by leaps and bounds, and there are many types of traditional diseases.

It's just that the limitations of technology and instruments, although there is a clearer understanding, have also brought more controversy.

Just one dysentery is divided into six categories, not to mention the details.

Originally, what Zhu Gaochi wanted was to eliminate all the messy prescriptions and the indiscriminate prescriptions, and only keep the ones that were effective.

But how is the development of science smooth sailing?

Truly.

A large number of prescriptions with low efficacy, as well as ineffective, or even counterproductive drugs have been eliminated, but not only have the prescriptions not decreased, but because of the development of medicine, more details have been separated, resulting in a slight increase in the total number of prescriptions.

During this period, no one could convince anyone, and there were many deadlocks in terms of results.

No one can say that the medicine will cure the disease, let alone that every patient can be cured, and what exactly has worked and so on is not visible to the naked eye.

In a word.

Several doctors from Jinzhou quarreled for two days, and seeing that Zhu Gaoxu was no longer good, someone finally compromised and reached an agreement on medication.

……

Capital.

The climate here is different from that of Beiping, and after the beginning of spring, the weather is not as cold as in the north, so you can play outside.

The north is definitely colder than the south.

The cold in the north is the degree of freezing to death, and the reason why later generations have said that the south is colder is because there is no indoor heating in the south.

Mandarin Palace.

Zhu Gaochi listened to the report of Xu Ning, the chief treasurer of the Railway Engineering Department, and several outstanding managers from other departments.

"Beiping, Baoding, Kaifeng, Wuchang, Changsha, Hengzhou, Yongzhou, Guilin, all open to traffic."

Xu Ning said excitedly.

Zhu Gaochi looked happy, how many years.

Railway projects have been built from scratch, and the scale of workers in the construction of railway projects in the country has also reached 600,000.

It took eight years to build the first railway from north to south in the Ming Dynasty, with a total distance of 4,500 miles.

Theoretically, the fastest speed, from Beiping to Guilin, Guangxi, only takes six days.

Of course, reality is impossible.

It takes about ten days to stop, dispatch, and replenish along the way, from Guilin, Guangxi to Beijing, from Changsha, from Jiangxi to Zhejiang, and then north to Beijing.

"Fortunately, with the full support of His Royal Highness the Imperial Grandson, otherwise how could the Ming Dynasty Railway be built so quickly."

Is it fast?

Hearing Xu Ning's statement, Zhu Gaochi didn't feel happy.

The total mileage of the railways in the Ming Dynasty has reached more than 21,000 miles, and the average number of railway workers per mile is 238.

Not counting the workers in the industrial chain behind it, it adds up to more.

However, this is also a big killer that drives production and construction, which directly pulls the national strength of the Ming Dynasty to a different level.

Xu Ning couldn't see Zhu Gaochi's heart, and continued to report as usual.

This is the merit of the Ministry of Railway Engineering, and he must make every word clear.

"The iron used to build railways is mainly steel, pig iron is too brittle and easy to crack, wrought iron is too soft, and it is easy to deform when exposed to high temperatures."

From wrought iron at the beginning to steel later, the technology of the Railway Engineering Department is also changing with each passing day under the market demand.

Zhu Gaochi knew what Xu Ning was talking about.

In ancient times, there was steelmaking

At least in the Northern and Southern Dynasties, there was already an initial steel-making method, which was called "steel filling", or "group steel".

"The so-called iron and steel in the world are bent with soft iron, and they are trapped in the middle of pig iron, sealed and refined in mud, and forged into each other, which is called mass steel, also known as steel filling."

It means that in the society, steelmaking is to bend wrought iron into a coil in a steelmaking furnace, and embed a piece of pig iron in the middle of the coiled wrought iron, and then seal the steelmaking furnace with mud for smelting. After refining, take it out and forge it. The steel smelted in this way is called group steel, also called steel filling.

This is the steelmaking method before the Song Dynasty, although it can make steel, but the output is low, the efficiency is low, and it can only meet the needs of the agricultural society.

By the middle of the Ming Dynasty, there were more advanced steelmaking processes, such as the steelmaking process mentioned in Tiangong Kaiwu.

Auxiliary materials for steelmaking, found cheaper, widely available, and with better results.

The use of steel furnaces has improved the temperature, quality and cost of iron smelting.

Then there was the middle and late Ming Dynasty.

The invention of Sugang.

The new steelmaking process, output and technology have undergone tremendous changes, and the process of Suzhou Iron and Steel has been used until the sixties of New China, which shows its advanced nature.

In a nutshell.

Before the Song Dynasty, the ancient steelmaking was still in the exploration stage, and it was not stable, during the Song Dynasty, the steelmaking technology was mature, but the production process led to limited output, and the late Ming Dynasty made a big breakthrough, and the output and technology rose to a new height.

Later, even the heavenly works disappeared in the Qing Dynasty, and the whole of China did not know that there was this book, and after the new China, there were still people who came back from Japan, and people knew that there were so many advanced technologies in ancient China.

I don't know how many books have disappeared, and not every book has the luck of heavenly creation, which can be circulated abroad and preserved.

Iron and steel production in the Qing Dynasty declined year by year, and it was not until the end of the Qing Dynasty that the Westernization Movement increased, and the previous steelmaking technology not only did not continue to develop, but declined and was lost.

In a word.

The Sugang method in the middle and late Ming Dynasty was invented two hundred years in advance, making an important contribution to the improvement of railroad tracks in the Ming Dynasty.

However, the traditional technology has been developed, and the iron-smelting technicians of the Miyun and Huguang divisions have built a taller steel-making furnace, and the output exceeds the output of the Suzhou steel process in the late Ming Dynasty.

Xu Ning sighed: "A total of 3.78 billion catties of iron were used for all kinds of iron. ”

1.85 million tons.

After so many years, it is nothing.

Zhu Gaochi still didn't care much.

Finally discovering the attitude of His Royal Highness the Imperial Grandson, Xu Ning couldn't help but be surprised.

His face didn't change.

The imperial grandson is really a very person, even if the saint heard about it, he was extremely shocked, not as calm as the imperial grandson.

It seems that the imperial grandson is more calm than the saint.
