Yan Zheng stayed in Nantou for ten days, and then stayed for two days when he passed through Qinzhong City to visit the local area.

The specific information obtained during the whole visit was very large, and we had a more intuitive understanding of all strata of the Chinese people.

I found many problems, but also found a lot of shining points, and I have a bottom in my heart about the work of the past five years.

The rapid development of the economy has brought about rapid changes in life, and the face of urban residents has changed greatly, and new concepts of the market class have begun to appear.

For example, the change in the attitude towards workers has given the old concept of craftsmanship a second spring in China.

The pursuits of the citizen class have also changed greatly, and they attach more importance to education than in rural areas.

These changes come from their own work, and as long as they are working families, they will be more receptive to knowledge and have a broader vision to demand from their children.

It's just that the fertility rate in the city is far less than that in the countryside, the gap is about double, and the cost of raising a baby in the city makes having a child for a long time only a net investment.

Unlike rural areas, as long as a child is seven or eight years old, he can help farm together, which is half a labor, and the cost of raising a baby is relatively low.

Therefore, the antagonism between urban and rural areas has already faintly emerged, and the change of concept will inevitably lead to cognitive differences, and this difference will lead to greater estrangement.

Along the way, Yan Zheng was thinking about the current situation of the countryside and the problems of the farmers.

As a result, he was very helpless, and he really couldn't think of a way to reverse this trend under such productivity.

Thinking about it, there are only two answers he can find, one is to continue to develop the productive forces, and the other is to expand!

It is necessary to make the peasants have a few hundred acres of land per capita, to allow them to plant hundreds of acres of land per household, and to let agricultural machinery replace most of the work.

If this is achieved, it will be like the great agriculture of the rice country in later generations.

The root of the formation of the agricultural model of the United States is not the good planning, but in the process of colonial development, it is naturally formed, and its fortunate place lies in the large-scale application of diesel engines at that time, resulting in exponential growth in productivity, and a large number of agricultural machinery was invented and manufactured.

It is impossible for Eastern Qin to have thousands of acres of land per capita, but a few hundred acres per capita can also solve big problems.

So for these conceptual things, Yan Zheng decided not to care! He originally wanted to oppose the old and cut the tail of feudalism.

But he knew that it wouldn't work very well. There was a sage who had already stepped on the pit for him, and for the sake of a better reputation for future generations, he chose to take a step back.

……

By the time I got back to Meadow, it was late May.

Before Yan Zheng arrived at the Red Room, he saw a group of people in uniforms waiting at the gate of the Third Courtyard.

They weren't a gang, just look at the costumes, one was from the shipyard, and the other was from the medical department.

They surrounded the carriage, and as soon as Yan Zheng got down, they bowed down in unison and said, "Your Majesty, we are here to say hello!" ”

Yan Zheng was stunned for a moment, and hurriedly asked, "Why do you have it?" ”

The people of the two groups humbly gave in, and Liu Chengyun, the director of the shipyard, was older, so he reported first: "Your Majesty, our shipyard has successfully built the five-masted, thousand-ton iron-ribbed wood-hulled sailboat you want!" ”

As he spoke, someone passed a model, and Liu Chengyun came forward with an excited face.

Yan Zheng solemnly took it, the five masts refer to the five tall main masts, if you really want to count, this ship has nine masts, using a cross-sail structure.

The bow looks a bit like a later ship, but it is more rounded, and the hull gets narrower the way to the stern, like an elongated droplet.

"The difficulties in the construction process have all been overcome?" Yan Zheng asked.

Liu Chengyun said smugly: "Don't hide it, it's the first time for our shipyard to build so many masts and thousand-ton ships, the main thing is the balance of the hull, unlike the transport ship that can build a big belly, and it doesn't matter if you sacrifice a little maneuverability." This ship has a combination of high masts and horizontal sails, so many masts and sails, just sorting it out is a door!

The victory lies in the spirit of daring to think and dare to do, insisting on being in charge of politics, building while practicing, and learning shipbuilding in shipbuilding. Deeply implement a series of spirits of the king, and then gradually grope for the way out, get the hull and mast ratio, the impact on the balance of the ship. With the calculations we've discovered, it's easy to build a bigger tonnage ship! ”

"That's awesome!" Yan Zheng was shocked, this group of people came up with a calculation formula?

Liu Chengyun said with a smile: "This is also the result of the help of the students of the physics department, and the concept of force analysis can be easily obtained!" However, this ship, built to about 1,000 tons, should also be the limit, at most it may be 1,500 tons! ”

"Why?"

"This ......" Liu Chengyun thought about and said: "It involves a series of reasons for the personnel handling the sail, the complexity of the sail, and the wind on the sail, when it exceeds a certain tonnage, then no matter what, the speed and difficulty of the ship will go up a big step!" ”

"Diminishing marginal returns!" Yan Zheng summarized.

Liu Chengyun didn't know this term, but said: "The results of this ship's trial voyage are very gratifying, its wave-riding hull, and the sails are tall, and it runs almost twice as fast as previous ships!" It is also resistant to wind and waves, and I believe that after a few more sea trials, it will be finalized! ”

Yan Zheng looked at the model with a smile on his face, what he didn't know was that this ship was equivalent to the flying clipping ship of later generations, and it was almost the same in terms of overall structure and principle.

Under the superposition of technology and knowledge, the bow design was drawn by Yan Zheng according to the ships of later generations, and the shipbuilding experts of the Eastern Qin Dynasty, who had mastered the iron-ribbed wood-hull shipbuilding, naturally came up with this ship, such a ultimate version of the sail warship era!

That's right! It's the ultimate version! If the tonnage is larger, then the gains outweigh the losses.

The clipper ship has only been in service for a short period of time in history, and the reason is that it has been eliminated by the rapid development of ironclad technology.

However, it set a record of only 89 days from Guangzhou to London, which is faster than the ironclad ships of the same period.

Yan Zheng said happily: "The shipyard has made great contributions, and Director Liu has been promoted to a higher title and become a special engineer!" The rest of the staff will also be promoted to the next level, and will be paid three months' salary as a bonus, allowing you shipyards to select the top ten outstanding craftsmen to have dinner with the monarch! ”

Liu Chengyun bowed excitedly and said, "Thank you, Your Excellency!" Long life without borders! ”

Yan Zheng looked at the Department of Medicine again, and saw that the student led by him took out a small glass bottle, which contained some yellow powder.

"Back to Junshang, with the help of the Department of Chemistry, the sulfonamide laboratory has been successfully prepared!" This time it was Du Wensong who came to report.

"Success?" Yan Zheng hurriedly took a look, "Have you verified the efficacy?" ”

Du Wensong replied: "Human live experiments have been conducted, and the injured laborers heal faster after taking and applying these powders than those who did not. Colony tests have also shown that it does work! ”

"The Sword Comes"

Yan Zheng looked at these powders, looked up in astonishment and said, "Dongqin's technology has really entered self-upgrading?" ”

A girl on the side couldn't help but smile: "It's just that large-scale production is still being discussed, but it's not more difficult than sulfuric acid production, and people in the chemistry department say that it takes two or three months to make a plan!" ”

Yan Zheng nodded: "Do it well!" As soon as sulfonamide comes out, Huaxia will be invincible in the world! ”

Historically, the discovery of sulfonamides was purely accidental, it was discovered from dyes, and scientists at that time found that they had an antibacterial effect.

And this dye has a history of more than 100 years, and if it were not for that accident, perhaps the discovery of sulfonamide would have been much later.

Therefore, the principle and process of preparation are not difficult, and what Dongqin prepared this time is only one of the sulfonamides, and the professional name should be called "p-aminobenzenesulfonphene".

However, in the current era, this drug can be described as an anti-heaven existence!

This kind of rebellion lies in the fact that he can chemically synthesize! This makes it less difficult to produce on a large scale, and although there are many side effects, it is effective against plague, respiratory infections, various types of inflammation, cholera, malaria and other diseases that can be found.

It is also extremely convenient for storage and transportation, and only needs to be taken orally during use, unlike penicillin, which will affect the efficacy of the drug when taken orally.

…………

After returning to the Red Room, Yan Zheng couldn't hide his excitement, he was half-lying on a chair, and there were ship models and sulfonamides on the table.

He didn't know how much this weight had in history, but this thing would definitely save an unknown number of lives!

In the future, as long as Dongqin plays hard to pile up production capacity and make sulfonamide the price of cabbage, then it will be regarded as saving hundreds of millions of Li people.

Many viral and bacterial infections will also be dealt with with by a miracle cure.

Yan Zheng looked at it for a while, and couldn't help but smile, as if it was a seed he sowed, and today it finally bore satisfactory fruits.

This can be regarded as a great contribution made by him and Dong Qin to the entire human civilization.

It's just that these contributions, in this era, are really a must-have medicine for armed colonization!

The sail runs fast and speeds up the reaction time on the ocean, and sulfonamide can cope with various diseases caused by colonies and viruses, and can avoid adaptation to water and soil.

This, combined with the amount of artemisinin already in production, is enough to make malaria no longer a threat.

As long as the production capacity is piled up, then Dongqin can really do whatever he wants!

"Lan Ya, go to the Ministry of Defense for me to give an order, and say that a conference will be held! Get them ready, the topic is Nanyang! ”
