No palace people knew why the emperor was suddenly depressed, even if the military situation was urgent and the finances were insufficient, they didn't see the emperor frowning and thinking about it like this.

"When the emperor leaves the palace, what people or things can he meet outside?" Wang Tiqian reported two good news to the emperor, and the emperor was only temporarily happy, he didn't know why, so he secretly called Fan Xiaohui out to ask.

Fan Xiaohui was also puzzled, tilted her head and frowned for a while, and said: "I talked and laughed with those students at the Academy of Sciences, and then I went back to the palace, and I didn't encounter anything!" ”

"Think about it again." Wang Tiqian didn't give up, and asked again: "The emperor is estimated to sleep in the warm pavilion tonight, you are waiting, don't make the emperor happy, you can be careful to punish him." ”

Fan Xiaohui blushed, the emperor's punishment is ashamed!

The girl pondered for a long time, and finally thought of the little thing about the mouse catching the mouse. It doesn't sound worth mentioning, but the emperor seems to have been unhappy since then.

Wang Tiqian touched his chin and thought about it, and guessed wildly: "Could it be that the emperor is worried about Bai Niangniang, and those cats eat mice, and feel disgusting?" ”

Saying that, Lao Wang turned his gaze to Fan Xiaohui and instructed: "You go and bring the emperor's favorite junior, or Xiaowu, to see if the emperor is because of this." ”

"Then what if the emperor is really angry?" Fan Xiaohui's eyes widened, very reluctantly.

Wang Tiqian put on a majestic posture, and Fan Xiaohui had no choice but to admit it and leave with a pout.

In the middle of the night, Fan Xiaohui walked into the hall with the cat in her arms, and when she saw the emperor's gaze turned, she immediately stood still, not daring to move forward.

Cats eat mice, can cats get plague? I don't think I've heard anything like this, why?

Zhu Youxiao's eyes were full of scrutiny and doubt, and he beckoned, and when Fan Xiaohui approached, he reached out and hugged the cat, looking at it thoughtfully and petting it.

Oh, it turned out not because cats eat mice. Fan Xiaohui breathed a sigh of relief, and said with a smile: "The cat is very well-behaved and cleanly cared for." ”

The emperor smiled, a little bitter, and a little helpless.

Of course, he knows that good hygiene habits can reduce the breeding of mosquitoes, flies, bed bugs and rats, and reduce the occurrence of various infectious diseases.

But most of the ordinary people of the Ming Dynasty are not wealthy, and they can bathe and change their clothes frequently. Garbage disposal in cities is not regulated, and contaminated drinking water is inevitable.

Of course, compared to the poor, dirty, and foul-smelling Europe of the Middle Ages, the Ming Dynasty was still good. Although this is still far from Zhu Youxiao's standard.

Personal hygiene habits, depending on the level of affluence, must have at least a few changes of clothes, and be able to afford soap and soap.

Public health requires government investment to continuously improve the urban system, such as sanitation, epidemic prevention, and so on. Growing from scratch will require sustained and huge funding.

The emperor held the cat up in front of him, and with a smile on his face, he jokingly asked, "Why do cats eat mice, why aren't you afraid of getting sick?" ”

Although the emperor didn't know it very well, he knew that cats eating mice were definitely good for the body, and it should be a supplement for the lack of some element.

Moreover, he also knew that the cat's immune system was estimated to be resistant to the plague bacteria. Just like a scavenger doesn't get sick from eating rotten food.

Meow! The cats squealed obediently, and stuck out their tongues to lick the emperor's hand.

The emperor laughed, and the happy look he showed made Fan Xiaohui and Wang Tiqian, who had been standing respectfully beside the hall, breathe a sigh of relief.

The emperor teased the cat for a while, then gave Fan Xiaohui again, turned his head and ordered: "Summoning the missionaries in Beijing to enter the palace tomorrow." ”

Foreign devils?! Fan Xiaohui blinked her eyes wide, looking forward to it. I've heard of it, but I haven't seen it with my own eyes, but this time I can see something new.

How did the Black Death stop in Europe?

Although Zhu Youxiao has his own guesses and judgments, he still wants to know more. In order to prepare in advance and prevent in advance.

This is not a trivial matter, but a major event related to the life and death of tens of millions of people. According to history, the plague killed more than 10 million people at the end of the Ming Dynasty. More than 10 million, wherever you put it, it is the population of a medium-sized country!

…………………….

Pingliao exterminates slaves, the power of the whole country, this is the main theme of the recent "Daming Tribune", and it is the word that appears the most often.

But no one would have thought that the emperor was still worried about mice, and even if he said it, no one understood.

Jiannu can be destroyed, and the tragic history will not be repeated. Even if he can't compete for all the success this time, it will only drag on for another year or two, that is, a few more years, and the emperor is confident.

But for the plague, the emperor knew that he could not stop it, let alone extinguish it. This, like the catastrophe of the Xiaoice period, is inevitable and will definitely come.

Since this is the case, the emperor also wants to open it and try his best to reduce the harm, and there is only one way.

Alas, knowing too much is the main reason for my own trouble. And the little carpenter in history, although he is a short-lived ghost, should be happier than himself, right?

Maybe that's how life is, and it's spent constantly solving problems. It's better to move step by step, deal with it one by one, and solve it one by one!

"Five hundred rockets were produced in such a short period of time?" Although the emperor was slightly surprised, he was more still admired, "Sun Qing has worked hard." ”

Sun Yuanhua hurriedly bowed down and humbly spoke, "Long live the praise, the duty of Weichen, I dare not say the word hard work." ”

The emperor smiled and said, "As for the operators, they can't be fully equipped, and they can't fully exert the power of the rocket!" ”

"Long live the kick-starter." Sun Yuanhua replied: "The rocket launch is simple, and only a small number of operators are needed. It's nothing more than a ranging measurement, and then roughly adjust the next direction. ”

The launcher is a triangular iron frame with an iron tube on top of it, and only the elevation angle can be adjusted after inserting the rocket. If you change direction, you can only move as a whole.

Simple to manufacture and easy to operate, this is precisely where the advantages of the rocket lie.

The accuracy is definitely not as good as artillery, but the maximum range can reach more than two thousand meters, which is nearly twice as far as the Hongyi artillery.

The emperor thought about it and thought that it was necessary to explain to the front-line generals to make full use of the ultra-long range of the rocket and use it at a critical moment to achieve the greatest effect.

After thinking about it, the emperor raised his head and asked with a kind face: "Xu Ge is concentrating on the study of agriculture, please resign from the president of the Academy of Sciences, Sun Qing is willing to serve." ”

The first president of the Academy of Sciences was Xu Guangqi, a well-deserved appointment.

However, while Xu Guangqi was revising the almanac, he also guided Chen Zilong and others to conduct agricultural research, and this dean was in name only, and he had no leisure to manage and guide.

Sun Yuanhua bowed and said, "Wechen is willing to go." ”

After a pause, he added: "But the work of the Gunpowder Weapons Bureau, Wei Chen feels that it is more important. ”
