Zhang Yifan remembered that Deng Yu, a famous general of the founding generation of the Ming Dynasty, was infected on the way to this class and died.

However, there is no record in history of what illness Deng Yu fell out of.

Thinking of this, he remembered something again, so he asked Zhu Biao, "What is the illness of my sister-in-law's father?"

In history, there was the same ending as Deng Yu, and there was also Chang Yuchun who was also on the way back from the war, and suddenly hung up.

There were conspiracy theories in later generations, saying that Zhu Yuanzhang felt that they had a high merit and could not be sealed, so he killed them.

In this regard, Zhang Yifan doesn't think so, no matter how powerful these generals are, can they be better than Xu Da? How did Xu Da not die of a violent illness?

Besides, Zhu Yuanzhang himself said publicly that the first hero of the founding of the Ming Dynasty was Li Shanchang, and he was fine, and he didn't kill Li Shanchang until Zhu Biao died in history, set up a young successor, and Zhu Yuanzhang himself had little time.

Therefore, when the power of the former yuan was still very large, it was said that Zhu Yuanzhang killed Chang Yuchun and Deng Yu because of his great merits, anyway, Zhang Yifan didn't believe it.

At this time, Zhang Yifan remembered it, and he wanted to know what the answer was?

Zhu Biao listened, and didn't know why he suddenly asked about this, but he immediately replied, "It's that he was infected with smallpox during the war."

At this point, he said gratefully, "Thanks to you for solving the smallpox problem, otherwise, I don't know how many people would have died in this smallpox trouble!"

Hearing this, Zhang Yifan suddenly remembered that like Chang Yuchun, a famous general of the Manchu Qing Dynasty in the late Ming Dynasty, an important figure in the Aixin Jueluo family, and the most famous son of Daishan, Yue Tuo, also contracted smallpox and hung up during an invasion of the pass, and failed to get out of the pass alive, which is recorded in history.

From this point of view, if anyone gets smallpox, it is really not a question of who is strong or not, but a blind box, bad luck, like this kind of generals with the strongest physical fitness, are easy to hang up when they are in their prime.

From this point of view, is it possible that Deng Yue hung up because of smallpox?

Thinking of this, Zhang Yifan hurriedly asked, "Then have all our Ming army been vaccinated with cowpox?"

Zhu Biao listened, nodded and replied, "Since you proved last year that vaccinia vaccination can prevent smallpox, my father was the first to vaccinate the border army......

Speaking of this, he paused, feeling that there was nothing to scruple in front of his brother-in-law, so he revealed the news: "I also let the border pass spread the smallpox plague to the enemy, and the same is true, when you compete with the fourth child, the commander of the border pass can rush back to the capital to watch the battle with more confidence."

"......" Zhang Yifan was speechless when he heard it.

The old man's sense of smell is really sensitive, and from the fact that the border army can be inoculated with cowpox without smallpox, he immediately thought of the advantages of the Ming army, and then created trouble for the enemy.

is really worthy of being the founding emperor, killed in the sea of corpses and blood, and with a little fighter, he can quickly seize and use it.

Thinking so, he asked Zhu Biao, "Then this also means that Wei Guogong's side has also been vaccinated with cowpox!"

"Of course!" Zhu Biao nodded and said, "Even Xiangshan County, which is so remote as you here, was vaccinated with cowpox before you came, so you still have to worry about the border army?"

After saying that, he felt that he was talking a little serious, so he explained: "The smallpox plague, as long as it is human, will be afraid, there is a solution, who doesn't want to solve it as soon as possible? Isn't it?"

"By the way, in terms of this matter, my father also issued a strict decree at the beginning, if there is still smallpox in the local area after a month, the magistrate will be held accountable."

When Zhang Yifan heard this, he felt a lot more relieved, so that there would be no one in the Ming Dynasty who died of smallpox.

That classmate Wei Guogong, will he change his fate?

Thinking of this, Zhang Yifan suddenly remembered that Queen Ma was also infected and died, although there was no record of what kind of disease Queen Ma was, but it was said that Queen Ma was sick when she was sleeping, and she knew that this disease could not be cured, so she did not let Zhu Yuanzhang be angry with the imperial doctor.

There was a TV series in later generations, and it was speculated that Queen Ma also died of smallpox. as

If that's the case, Queen Ma wouldn't have died at the age of fifty-one!

However, Zhang Yifan was a little suspicious of this cause of death.

Chang Yuchun and Deng Yu, both in their early forties, died suddenly when they were in the prime of life. It stands to reason that their bodies are strong, and ordinary diseases are not easy to kill them.

The most important thing is that if the two of them died of smallpox, the guards around them would die with them, and it would be nothing if they didn't leave any records in history, after all, they were just guards, and they were not famous at all.

But Queen Ma is different, she is in the courtyard of the deep palace, where does smallpox come from? And if she has smallpox, the people around her are infected, such as other concubines, even Zhu Yuanzhang, so it is impossible not to record this incident in the history books, right?

Therefore, Zhang Yifan did not believe that Queen Ma died of smallpox. However, he is not a doctor either, so I don't know what kind of illness Queen Ma might have died?

He was thinking about this, but Zhu Biao's mind no longer thought about smallpox, and he no longer even mentioned the matter of the prime minister, but said to Zhang Yifan: "The statement of shares you mentioned to your father is the common interest, dividends and money just mentioned, right?"

"Well, yes." When Zhang Yifan heard this, he explained, "In this way, the imperial court can also use other people's money to do things that originally required a lot of money to do without having to pay more. And because of the binding of interests, it will be more efficient to do things."

There is a loan from Qianzhuang as a reference, for example, the county government of Xiangshan County has built so many cement houses, but only a small part of the money is taken as an example, Zhu Biao can already understand this matter, so he replied to Zhang Yifan: "Okay, I know about this matter, and I will explain it to my father in detail when I go back."

Speaking of this, he immediately continued to the next topic: "Also, what patent did you mention to my father, this matter, my father has concerns, and I feel that it is not easy to do."

"Huh?" Zhang Yifan listened and was a little puzzled.

When Zhu Biao saw it, he explained to him: "The main thing is that you have mentioned this unique skill, how to prove that it is his unique skill, maybe Jiangxi people will do this, Shandong people will also do this, if the court recognizes Jiangxi people, then what should Shandong people do?"

"Also, if Haoqiang forcibly occupies someone's unique skills and comes to the court to admit it, then does that person even have to look at his own unique skills?"

"The most important point, since it is a unique skill, why should you tell the court that it is not good to keep it for your children and grandchildren? The protection of the imperial court is only a few decades, how can it be passed on to children and grandchildren?"

「……」

Listening to Zhu Biao talking one by one, Zhang Yifan can confirm that the father-in-law and the eldest brother have indeed been seriously considered. Judging from the situation they summed up, they still thought simply.

The good things of the future may not be suitable for this time.

Listening to Zhu Biao's statement, there is actually a problem, that is, the people's distrust of the imperial court.

After a while, Zhu Biao said that he was almost done, and asked Zhang Yifan, "Look, what kind of patent matter is this, I'm afraid it's not easy to handle?" Do you have any other ideas?"

I didn't reply to Zhang Yifan before, firstly, because Zhu Yuanzhang was busy at the time, and secondly, it was too troublesome to communicate by letter, and when Zhu Biao came, it was much easier to communicate in person.

When Zhang Yifan heard this, he said what he had just thought about and said, "Big brother, look, how about we change like this?"

"You say!" When Zhu Biao heard this, he was immediately overjoyed, and he could hear that his brother-in-law still said this after knowing these problems, which means that there is a solution to these things.

So, I heard Zhang Yifan say to him: "Take the cement workshop as an example, the cement workshop we have fired at present, in fact, there should be something that can be improved, such as the formula, is it better to add anything else to the cement that is fired, and there are more applications? Or maybe it would be more cost-effective......

Zhu Biao actually thinks that this cement is very good!

However, after Zhang Yifan put forward various possibilities, he didn't dare to ensure whether there would be better cement.

Therefore, he listened carefully to see what Zhang Yifan wanted to say.

「…… Therefore, I plan to set up a research group within the cement workshop, that is, to send people who are proficient in cement firing and have the brains to try how to improve cement. I think it's necessary to spend this money, and this manpower."

"In addition, the fish floss workshop has also set up a research group to see how to make it cheaper and more delicious? You can't always rely on Jing Jing, you have to have someone else do it."

"In addition, in agriculture, the cultivation of rice, fruits, etc., in Lingnan, a research group has also been set up to study how to increase yields."

Zhang Yifan gave a few examples in one breath before concluding: "If these research groups have achieved results, then reward them and encourage them to continue their efforts; If the method is useful to the whole world, then the imperial court should also protect it, and rewarding these workshops is tantamount to encouraging these workshops to do these research. This is also a patent protection, but it is not for ordinary people, but for workshops. After these have been implemented for a long time and are familiar, it may be feasible to promote them to the people. Look, how about that?"

Zhu Biao listened, nodded and said, "You can say that, I think it's okay."

However, immediately after that, he changed his words and said, "But can those craftsmen produce any results? With their knowledge, can they push the boundaries and make something better than what is currently being made?"

This is indeed a key point, Zhang Yifan listened, and replied to Zhu Biao: "Indeed, the probability of getting results is very low. However, if we train them to be able to read and write, read more and analyze more, and make them more knowledgeable, will it be more likely that they will get some results?"

If the old farmer who farms the land comes to study, he will only know the point himself, even if he is good at pondering, it is equivalent to working behind closed doors, and it is really difficult to achieve results.

This principle is also suitable for research in other industries.

This is also why, in ancient times, people who read books have always been respected, because through reading, they can understand more, open their horizons, and naturally it will be easier to bring forth the new.

If it was somewhere else, Zhu Biao might still have doubts, but after visiting Xiangshan County in the past few days, he immediately understood Zhang Yifan's intentions, and immediately asked with a little surprise: "So, you are trying to make the people literate in Xiangshan County, so you have this consideration?"

Ordinary craftsmen must have low creativity, but if there are literate craftsmen, their creativity will be high, which is a natural thing to think of!

Zhang Yifan heard this, and immediately responded: "That's right, and what they learn is not traditional books such as poetry and songs, four books and five classics, but miscellaneous studies, those related to their own work. In this way, it will be easier for them to know what is going on and then why they will be able to learn from the strengths of others, and it will be easier for them to produce results."

After a pause, he added, "I thought of a part, summarized some rules, and wrote books and put them in the library, but no one has borrowed them yet. The main reason is that the level of knowledge here in Xiangshan County is still very low, and it is in the process of literacy."

When Zhu Biao heard this, he immediately became interested, so he stood up and said, "Let's go, go to your library and have a look."

When I visited before, I didn't go to the library pavilion, of course, Song Lian and they went by themselves, anyway, Zhu Biao didn't go.

Compared with other emperors, Zhu Yuanzhang is definitely a pragmatic emperor, and now that the Ming Dynasty is only in its tenth year, Zhu Yuanzhang is still looking for what doctrine to adopt for his concept of governing the country?

Influenced by him, Zhu Biao is naturally also a pragmatic prince. After visiting Xiangshan County, he felt the prosperity of Xiangshan County, listened to Zhang Yifan's explanation, and felt the economic benefits of the so-called miscellaneous science, of course he was interested.

Zhang Yifan saw that Zhu Biao was very interested, he was naturally happy, of course he was accompanied, so he stood up and said, "Then say hello to my sister-in-law, and say that we are out."

"Hehe, no, just let them toss there!" Zhu Biao listened, just smiled and replied.

In the backyard of the county government, Zhang Yifan dug a small swimming pool and taught Zhu Jingjing to swim; Now Zhu Jingjing has become the head of the sect and is teaching the crown princess and Zhu Xiongying to swim.

In this kind of weather in Lingnan, playing in the water is actually a kind of enjoyment, even if you can't learn to swim

Swimming, you can have a lot of fun.

When Zhang Yifan heard this, he said to Zhu Biao: "Big brother, if you learn it again, you can easily learn to swim." When the time comes, I will teach you, or let my sister-in-law teach you the same."

If the Ming Emperor could swim, it is estimated that there would be fewer emperors who fell into the water and died. In the original history, Emperor Zhengde and Emperor Tianqi seemed to be related to falling into the water.

Zhu Biao listened, just smiled and did not reply to this matter.

He has been here in Xiangshan County for a while, and he can't stay in Xiangshan County all the time, but everything in Xiangshan County is too novel, and there is still a lot to see, so if you want to, you are busy! ………………

The library pavilion is not far from the county office, and it is only a few steps away.

What Zhang Yifan and Zhu Biao didn't expect was that Song Lian's master and apprentice who went out for a stroll were actually in the reading room of this library pavilion.

When Zhang Yifan built this library, it was built in the style of the library of later generations, and there was a reading room where you could read books quietly.

Moreover, he has very high standards for this library, for example, the ice cubes that can only be enjoyed in the county government are also available here in the library.

In this way, on such a hot day in Xiangshan County, the library has become a popular place to escape the summer, and it is still free, but the premise is to read books carefully here, otherwise you will be driven away.

It is also for this reason that the library is famous in Xiangshan County and even other places, and many people are willing to come to the library to read books even if they are trying to escape the summer, which also invisibly promotes the literary style of Xiangshan County.

There are three reading rooms, two of which are quiet places to read books, and the other is separated by a baffle that allows for whispered discussions about problems encountered in reading.

As soon as Zhu Biao and Zhang Yifan came over, some people came over to tell them that Song Lian's master and apprentice were discussing the problem.

However, Zhu Biao did not go over immediately, but first looked at the two reading rooms closest to him, and found that many people in them were reading carefully, so he didn't go in, so he went to the library to check the scale of the library.

The library is divided into two layers, the outer layer, where borrowers can look through the books they want to see by themselves, and if they feel that they want to see them, they can take the books to the administrator to go through the procedures;

On the inner layer, borrowers can't look through it, they can only see the corresponding book introduction, and if they want to see it, they need the administrator to help them get it.

Zhu Biao took a look, there are many kinds of books here, from subsets of scriptures and history to religious classics, to hundreds of schools of thought, poetry and songs, etc., but if you want to talk about the amount, it is really not very large.

Zhang Yifan accompanied Zhu Biao and gave him nothing to say, "This is still the result of the reward, and I sent someone to buy all the bookstores in Guangzhou. If we want to continue to expand the scale of the collection, I'm afraid we will have to go to Jiangnan to collect them."

Starting from the Eastern Jin Dynasty, especially the southward migration of the Song Dynasty, it led to the prosperity of Jiangnan and the prosperity of literary style. Other places, after all, are not as good as Jiangnan.

Although Zhang Yifan felt still dissatisfied, Zhu Biao was very surprised, and praised repeatedly: "It's great that there is such a library here in Lingnan."

After finishing speaking, he asked with some curiosity, "Didn't you say that there are many books that you have written?" Why didn't I see that?"

Zhang Yifan listened, smiled bitterly, pointed to a large empty area next to him with his hand and said, "Most of the books are there, and they have been borrowed!"

When Zhu Biao saw it, he was very surprised and said, "What kind of books are they, so popular?"

Zhang Yifan listened to it and replied: "One set of "The Legend of Sword and Fairy", one set of "Zhu Xian", and one set of "Three Heroes and Five Righteousness", anyway, Jing Jing is clamoring to hear the story, she wrote them all down, printed them into a book, some of them are sold, and some are collected here."

One thing he didn't expect was that "Three Heroes and Five Righteousness" was more sought after than other Xianxia genres.

Zhu Biao has read some "The Legend of Sword and Fairy", mainly because the way of writing in it has been discussed with his father, but he is busy with political affairs, even if he is interested, he doesn't have time to read these idle books.

At this time, when he heard Zhang Yifan's words, he said to him with a smile: "You, you are still idle, such a good brain, you have time to think about this, you might as well think about other useful things!"

When Zhang Yifan heard it, he disagreed.
