Once upon a time, the three major battalions of the Beijing Division were well-deserved elites of the Ming Dynasty.

It's just that later the legend of invincibility was buried in the hands of the god of war.

Zhu Youzhen didn't expect to be able to train a group of elite divisions who could fight well in ten days and a half months. But no matter how you pull it out, you are all old, weak, sick and disabled, and all of them are running around in a battle.

His requirements are not high, just don't be scared and weak when you see Jiannu.

The 10,000 Shenji battalion equipped with Minne rifles was basically invincible in this era, and the platoon shot could knock the infantry of Jiannu out of.

But no matter how advanced the weapon is, the person who uses it cannot be coerced.

At present, the Yongwei Battalion has just been reequipped with a new type of Migne rifle, and the production efficiency of the arsenal is limited, and it will take two months to reload all the muskets of the Shenji Battalion.

Returning to the palace from Beijing, Zhu Youzhen continued to devote himself to academic research.

He found that there was an electronic version of the Encyclopedia of Land Law in the mall.

To be precise, it is a compendium of local law, which records a variety of technical means.

He learned to be obedient this time and asked the system customer service directly.

"Can you help me sort and print out what I bought?"

The agent was silent for a few minutes.

"Gotta add money! Ten pieces a piece. ”

"Why don't you go...... Forget it, print it. ”

It doesn't seem to make much sense to talk about the system.

Soon, two stacks of A4 paper printed and bound with the earth-based technique appeared in front of him. The system is very intimate and classified, and the traditional Chinese is transformed.

Agriculture, Industry, Animal Husbandry, Medical, Water Conservancy, Military ...... The whole nine yards.

Flipping through the pages, an agricultural technique caught his attention.

"Soil and Fertilizer"

It contains detailed descriptions of the methods used to make chemical fertilizers from soil, as well as the types and manufacturing methods of chemical fertilizers.

Zhu Youzhen studied for a while, and then threw it aside.

Artificial feces, artificial urine.

He couldn't understand complicated things, but he learned how to make urea at once.

Pour human urine into an iron pot and boil it so that the water vapor evaporates, leaving pure urine. Fry semi-dry, then put it in a bucket of 40% alkali powder and stir it thoroughly, mix it into a paste and pour it on the yang ash ground. The pale white crystals formed are urea.

It sounds a little unclean, but it has a great effect on increasing grain production.

Zhu Youzhen looked at all kinds of great knowledge in the book in amazement, to be honest, he had never learned so much in his previous life. He didn't look at it anymore, he was afraid that he wouldn't be able to help but cook urea if he looked at it again.

This thing should be handed over to Dean Song, a full-time master, and after he has researched the results, it will be handed over to the Ministry of Industry for national promotion.

All provinces, prefectures, and states are engaged in making soil fertilizers, and strive to make soil fertilizers bloom all over the country!

Zhu Youzhen held on to the two stacks of materials and fell into deep thought.

The preciousness of these things is self-evident, but he can't do everything himself. He didn't learn that much, and he didn't have that much time.

The idea of starting a school came to his mind again.

I have considered this issue before, and some people have been trained like a military academy, and they have slowly developed and grown.

But Confucianism, which has been inherited for thousands of years, has to be taken seriously, and if you change the system rashly, you will set yourself on fire if you are not careful.

After a long time, Zhu Youzhen sighed.

Take your time, hold the gun tight, and then talk about it slowly.

He stretched and was about to order someone to put away the precious information.

Wang Chengen walked in in from outside in a panic.

"Hooray, the little flower has smallpox!"

"What?"

Zhu Youzhen was shocked.

"What about people?"

"In the harem."

"Let's go, let's see."

"Hooray......

"What's wrong?" Zhu Youzhen frowned.

"Recently, Xiaohua and the prince have been in contact very frequently."

Zhu Youzhen was silent, he knew what Wang Chengen meant.

"I know, you quickly ordered the Yongwei battalion to seal off the palace, and you are not allowed to enter or leave the palace gate without permission. Also, order someone to go and find the cow quickly, and remember, be sure to look for the one with the pox. ”

Wang Chengen didn't mention the prince to prove that he was fine.

"Yes!" Wang Chengen walked out quickly.

Zhu Youzhen came to Li Xiaohua's residence in the harem.

To be exact, it is Li Zhao's residence, a hut in the Shangfu Bureau.

When the palace ladies saw the emperor coming, they hurriedly knelt down and saluted.

Zhu Youzhen walked into the house and found that only Li Zhao was standing by Li Xiaohua's side, Li Xiaohua was lying on the bed, wrapped in a quilt on a hot day, still shivering.

Zhu Youzhen walked over and touched Li Xiaohua's forehead, which was terrifyingly hot. I bought a forehead thermometer and measured it at 39.2 degrees Celsius.

"Have anyone from the hospital been here?"

"Long live Hui, I've been here, I've prescribed medicine and left. It is said that it depends on the will of God. Li Zhao touched a handful of tears and replied.

"You feed Xiaohua these two medicines first. Take her quilt away too, and don't cover up anything! ”

Zhu Youzhen took out amoxicillin and ibuprofen suspension and handed it to Li Zhao.

Li Zhao took the medicine and helped Li Xiaohua up, and Zhu Youzhen saw that Li Xiaohua already had two herpes on her face.

Li Xiaohua saw Zhu Youzhen on the side and smiled at him reluctantly.

"Brother Emperor, am I going to die? The adult who treated me said I might be dying. ”

"He scared you, be obedient, take the medicine first."

Li Xiaohua nodded, obediently took the medicine, and spoke again.

"Brother Emperor, can I meet my brother? I'm afraid I won't see him if I'm dead. ”

......

"Good!"

You are contagious, haven't you seen that those palace maids are far away from your mother?

But he really couldn't bear to tell Li Xiaohua.

Leaving the Shangfu Bureau, Zhu Youzhen returned to the Qianqing Palace. Zhou Yufeng, he doesn't plan to go for the time being.

An hour later, Wang Chenen walked in.

"Hooray, the cow has been found. A total of 180 heads! ”

......

When Zhu Youzhen came to the Shangfu Bureau again, Li Xiaohua's fever had subsided, and although her spirit was still not very good, she was no longer shivering. I think antibiotics and antipyretics worked.

Next, Zhu Youjian began to vaccinate everyone in the palace to prevent smallpox.

At this time, there was also a lot of discussion outside the palace, and the emperor blocked the palace again.

I heard that someone in the palace seems to have smallpox?

What are those eunuchs doing with a herd of cows into the palace?

Three days later

Kunning Palace

Zhu Youzhen stretched out his fingers to play with his son Zhu Cihong, and before he came, he took a special shower and changed into clean clothes.

"Hooray, how is the little flower?"

"It's been three days, except for a fever yesterday, and today it's been a good day. Come to think of it, it's no longer a problem. ”

"That's good. What vaccinia does this vaccination really protect against smallpox? ”

"Yes. As long as you are vaccinated with cowpox, you will never get smallpox in your life. ”

"That's great. If only the whole world knew about this method, not so many people would have died. ”

Zhu Youzhen nodded thoughtfully.

Li Dingguo only learned the news of his sister's illness on the third day.

Zhu Youzhen was afraid that he would be worried, so he waited for Li Xiaohua's condition to stabilize before ordering someone to notify him.

When his classmates learned the news, they all sweated for Li Xiaohua. If you have this disease this year, you can call it nine deaths. True life and death have destiny and wealth in the sky.

Li Dingguo was admitted to the palace, and after being inoculated with cowpox, he met Li Xiaohua. She is in good spirits, and the herpes on her face are slowly scabbing over. Thankfully, there are only two.

"Sister!"

"Rujing, did you vaccinate the cowpox when you entered the palace? The emperor's brother said that as long as you get vaccinated, you won't get sick anymore. ”

"Planted! Planted a knife! ”

"That's good! You won't get smallpox! ”

Li Dingguo nodded and looked at the scar on his sister's face. Said softly.

"I beat Zhang Erhu a few days ago!"
