Chen Wanrong originally wanted to gradually spread it out, but unexpectedly, as soon as Li Longji arrived, the matter changed and he became a big deal. Five hundred Imperial College students and two thousand county library students were a big deal, and there were more students in the military weapon supervisors. How could Chen Wanrong and the others jump up unhappily?

Li Longji continued, saying: "Don't be busy thanking you first. These incidents are important. If you can't do it well, I will say ugly things ahead, and you will not be able to escape punishment."

Chen Wanrong took the conversation without thinking and said, "Your Majesty, you can just put one hundred and twenty thoughts on it, so there will be no problem with the certificate. Your Majesty, when did you say anything big?"

"It hasn't been before, it's hard to say in the future!" Li Longji would not follow Chen Wanrong's words, which made everyone laugh.

After everyone laughed, Li Longji continued: "You have to do a lot of things. You can't grab your beard and eyebrows at once. I will give you some points. All of these things must be used. Sulfuric acid is the most important thing, so there is no need to mention this. After making sulfuric acid, you must first create medicine for treating severe cold and fever. This is a stubborn disease that has been stubborn for thousands of years and may cause disasters at any time and must be put first."

Plague is known as "the fish that slips through the net in historians". Historians of all generations have focused on military and national affairs. They often use the simplest few strokes to describe the plague, and some of them are not mentioned at all. Therefore, we cannot now explore the scale, scope, number of deaths, and response methods of the plague.

Even so, there were still a few claws that revealed the information that the plague had killed countless people, and severe cold and fever were one of the most severe diseases. During the Ming Dynasty, Jiangnan's disease caused a disaster, killing nearly one million people.

Severe cold and heat diseases, that is, abuse of diseases. When the weather turns hot, it will be more or less popular and sometimes cause disasters. This medicine is indeed the most urgently needed.

Everyone had no objection to Li Longji's statement and said in unison: "The emperor is wise!"

Li Longji added: "I will also issue an order to the whole country, and local officials must collect stinky artemisia first, just waiting for you to make sulfuric acid."

Although we have to plant stinky artemisia, there is a process, so we should collect it first. This way, there is nothing to say. Chen Wanrong and others admire Li Longji from the bottom of their hearts, and it is another praise.

"Oh!" Li Longji slapped his forehead, as if he had remembered something, and asked, "Chen Wanrong, can you make fertilizer? Can you cure the diseases and pests of crops?"

China is a traditional agricultural power. It is based on agriculture and attaches much importance to agriculture far beyond our imagination. Li Longji is well aware of the importance of agriculture and is always talking about it.

What he asked was another question that had troubled countless people. The diseases and pests of crops made the ancients helpless. Ye Tianheng and the others suddenly realized and looked at Chen Wanrong involuntarily.

Chen Wanrong nodded: "Prince, please rest assured that as long as sulfuric acid is made, it can be used as a drug to prevent and control crop diseases and pests."

"Wanrong, is there such a good thing?" Chen Laoshi was born in a mud-legged manner and couldn't help it when he heard this.

Chen Wanrong was very sure: "That's of course. To prepare this medicine, we can now mix a pound of gallbladder and a pound of lime, mixed with a pound of water, and sprayed on the leaves of the crops to prevent and control pests."

"Cyclone?" Li Longji's eyes suddenly widened and said with a lot of blame: "Chen Wanrong, how dare you use it to make glass? How dare you? No matter how important glass is, can it be bigger than growing crops?"

It was quite a bit of accusation. Agriculture was really too important to the Tang people. Ye Tianheng and others complained that Chen Wanrong was ignorant of the importance of it.

Chen Wanrong said calmly: "Your Majesty, you don't know anything about this. The main reason why I use gallbladder and alum for glass instead of growing crops is that the number of gallbladder and alum we collect is limited, and it is impossible to use it on a large scale. Furthermore, without the tools I need, it is impossible to have these products. Where should I start with the prevention and control of diseases and pests?"

Thinking about this, Li Longji couldn't help but feel relieved, frown and loosened his eyebrows, and asked, "Is it really effective?"

The formula Chen Wanrong mentioned is the simplest and has good effect, called Bordeaux liquid, which has been used in agriculture for a long time, and of course it is effective. Chen Wanrong can completely pat his chest to ensure: "Prince, please rest assured, the certificate is effective."

As soon as he finished speaking, Li Longji's eyes shone and he kept rubbing his hands. Before he could speak, Ye Tianheng and the others started to talk to each other: "It turns out that there is such a good thing, we don't know. General Chen, have you hidden it again? If the emperor hadn't said it, you wouldn't have said it, it's true."

I have not complained about Chen Wanrong so much, let alone in front of Li Longji. This matter is really too important. If there are such pesticides, crops will suffer from less pests and diseases. I don’t know how much food is for increasing income. I don’t need to say how important it is.

Chen Wanrong smiled and said, "It's not that I didn't say it, it's that I didn't remember it."

Li Longji pointed at Chen Wanrong and said, "Chen Wanrong, if you forget such an important thing again, don't blame me for being rude to you. Do you know how important this matter is to the court? No matter what you want to do, you must first fill your stomach. If you can't be full, everything will be in vain. This matter is so important! By the way, just picking it from the fields is too little, so how can you make more alum?"

Everyone here knows the importance of agriculture, and their eyes are suddenly focused on Chen Wanrong, waiting for his answer. No one speaks, but only hears the sound of breathing.

Chen Wanrong smiled: "Master, why is this difficult?"

Li Longji, who has always been steady, suddenly became anxious and asked, "How to do this? What materials are needed? If you have difficulties, just say it, I will definitely help you solve it!"

Li Longji's stable and steady figure is difficult and difficult to make him anxious. Chen Wanrong had never seen him so anxious, and couldn't help but be surprised and pondered for a moment: "Your Majesty, there are no other difficulties, it's just that it requires a lot of copper. I wonder if the court can give it to you?"

In ancient times, copper was a strategic resource and used to mint coins. The Kaiyuan Tongbao (which should be called Kaitong Yuanbao) of the Tang Dynasty was made of copper, and the copper required a lot of money. Sometimes, because copper is expensive and the money is cheap, bad people melted the money to sell silver and made huge profits from it.

Copper was related to the economic stability of the Tang Dynasty. Li Longji agreed to use copper sulfate.

This matter is of great importance, and Li Longji couldn't help but be stunned: "Is there any other way to use copper?"

Chen Wanrong nodded with great affirmation: "Yes, the emperor!"

Li Longji did not speak immediately, but frowned and thought, "Bronze is very important to the court. I can't decide this for a while, so I have to think about it for a while." He patted his forehead and suddenly laughed: "I am really worried. Copper is smelted by military weapons. It's not enough. Find a military weapon supervisor! Chen Wanrong, I agree to this matter. You can solve the problem of copper yourself."

He really knows how to give up, Chen Wanrong was stunned. Li Longji continued: "Fat and alum are put second, and you must make it as soon as possible. When you make it, try it in Guanzhong first. Then promote it. Youzhou, Central Plains, Bashu, Jiangnan, Jianghan and Lingnan all need to use it. As for soda ash, let's take it slow first and solve the grain first."

Guanzhong, Youzhou, Central Plains, Bashu, Jiangnan, Jianghan, and Lingnan are all major granaries in China. Guanzhong is the "800-mile Qinchuan". It is precisely with the fertile soil of the Guanzhong Plain that the Qin State rose and finally unified China. In addition, Chang'an is in Guanzhong, so the importance of the Guanzhong Plain needs no need to say, and naturally it must be put first.

One of the most important reasons why Chang'an's transportation is so developed is that it needs to transfer grain from various places to Chang'an. Once the grain transportation is not smooth, there will be major problems in Guanzhong, and it is inevitable that the government and the country will be shaken. Trial is first made in Guanzhong. If Guanzhong can support Chang'an's grain demand, the pressure on the grain transportation will be reduced.

Li Longji's vision was very far-reaching, but there was no stroke of the eight characters, and the cucumber had not yet been stalked, which was too advanced.

He spoke lightly, and Chen Wanrong was stunned when he heard it. The 800-mile Qinchuan in Guanzhong; Youzhou is the current North China Plain, which is the most important strategic barrier of the Tang Dynasty in the north; Bashu, the country of Tianfu; the rich water towns in the south of the Yangtze River; the Jianghan Plain; the "Pearl River Delta" in Lingnan, and the hinterland of the Central Plains. All of them are famous granaries in China.

No one can tell how many fertile fields there are here, so they can only say a lot. Correspondingly, there is a lot of demand for phosphate fertilizers and agriculture, and it is not an exaggeration to say that it is an astronomical figure. To meet the needs of these granaries, it takes at least ten years of effort, and it may not be possible to achieve it in ten years. Can soda ash be discharged?

Seeing Chen Wanrong's dazed look in his eyes, Li Longji asked, "What's wrong? Is there a problem?"

Chen Wanrong woke up and said, "Your Majesty, there is no problem, there is a big problem! Your Majesty, do you know how much sulfuric acid is needed just these two things? It's not tens of thousands of kilograms, not hundreds of thousands of kilograms, not millions of kilograms, it's as much as 100 million! How can I do so much?"

"If you can't do it, you have to do it! If you can do it, you will be granted your Duke! If you can't do it well, go to the Heavenly Prison!" Li Longji was very relaxed: "Chen Wanrong, no matter how much military achievements you make, I will not be granted your title. Only when you do these things well can I be granted your title. I just want people to see that in the Tang Dynasty, in addition to military merits and talents, people like you can also get titles!"

Chen Wanrong doesn't care whether he has a good job or not, he just wants to do things.

"What I said is the granary of the Tang Dynasty, which is related to the fate of the country." Li Longji continued: "If you do it well, it will be more meaningful than destroying ten Tubos. It is natural to be a master of your country, and no one dares to say anything! This is a great difficulty. Let's do it, first expand the military weapon supervision ten times, and then expand it according to the situation."

"Ten times larger?" Ye Tianheng and his friends almost fell to the ground, staring at Li Longji in surprise.

The military weapon surveillance is now quite large. If it expands ten times, how many people will it take? How big is it? It makes people dizzy to think about it. Ye Tianheng and the others can't be surprised.

Li Longji frowned and said, "What I need most is manpower. I can only give you so many people at the moment, and I will find a way later."

Chen Wanrong's eyes rolled and he hurriedly said, "Your Majesty, I have a way."

"Oh, let's talk about it." Chen Wanrong said excitedly: "Your Majesty, you know that these large granaries alone have been busy with military weapons for ten years. This requires a lot of people, and we have to cultivate them from now on. I want to ask the emperor to allocate a piece of land for me, build a school building, set up a classroom, gather the intelligent boys of the Tang Dynasty and teach them since childhood."

Li Longjis asked: "This is indeed a long-term solution. It is not a long-term solution just by transferring people from the Imperial College and the county office. It is feasible, I'm sure! There are many people, so you can't put them in the Imperial College. You have to find another place to build a school building. This is learning skills, what's the name?"

"University of Science and Technology!" Chen Wanrong blurted out.

Li Longji commented: "This is a learning skill, and it's not bad to call it technology. Does university have any hindering the words of saints?" There is a saying of "university" in the Confucian classics.

Chen Wanrong explained: "Your Majesty, wouldn't it just show that the Tang Dynasty attaches importance to the learning of skills?"

Since Chen Wanrong took over the military weapon surveillance, the changes in the military weapon surveillance have been greatly changed, and Li Longji saw it. Now, Chen Wanrong has drawn a better blueprint and the prospects are even more wonderful. How could Li Longji, a wise king with the power of the emperor, not realize it? After thinking about it, he said, "Since that's the case, let's do it. When it is built, I will write the inscription myself."

With Li Longji's inscription, this university of science and technology can be opened for a long time. Chen Wanrong is in charge of this university and can divide the subjects according to the standards of modern universities and systematically impart scientific and technological knowledge.

Opening a university in the Tang Dynasty and allowing modern scientific and technological theory to take root in the Tang Dynasty was something Chen Wanrong dreamed of, but there was no chance. Now, it was finally realized, Chen Wanrong was so happy that he could not say.

Of course, Chen Wanrong seized the opportunity well. If Li Longji hadn't wanted to solve the food problem, Chen Wanrong would really not be able to explain clearly when it would be done.

Li Longji was still interested: "You haven't told me about the way to be alum. Come on, let me tell you."

Ye Tianheng and the others were immersed in the joy of expanding the military weapon surveillance, and did not think of this. When they heard this, they couldn't help but agree in unison: "Speak quickly, speak quickly."

Chen Wanrong said: "Master, this is not difficult. It's just to burn the copper to black and then react with sulfuric acid."

"It's that simple?" Li Longji was very surprised. The alum could only be obtained from nature. According to his thoughts, it must be very complicated to rely on artificial manufacturing. It was too surprising that he could only say a single sentence.

Not only Li Longji was surprised, but even Ye Tianheng and the others were also unbelievable. Princess Yuzhen's eyes widened: "You are hiding your own private matters?"

Chen Wanrong shook his head very firmly and said, "Absolutely no."

There are many methods to make copper sulfate from copper, and the most suitable method for the Tang Dynasty is this. First, roast the copper to make it black, which is to generate copper oxide through heating. The copper oxide reacts with sulfuric acid, and then produces copper sulfate.

What Chen Wanrong said was definitely the truth, and everyone had to believe it. Li Longji smiled and said, "This record should be added. This record can be published and distributed to everyone. Remember, keep it confidential."

This is inevitable, Chen Wanrong and others received the order.

Li Longji was in a good mood today. After hearing so many good things, he was in an extremely good mood: "Chen Wanrong, I came to you, you won't say you don't care about a meal, right? Come and serve the food, let's have a few drinks!"

Although this New Year has not ended, good things continue to happen, and good news comes one after another. Ye Tianheng and the others are particularly happy and think they should have a few drinks, and agree in unison.

Chen Wanrong ordered, and the banquet was on the table soon. Everyone was in a good mood, chatting and laughing at the dinner, and the cups were coming and going, and they were having fun until the fun ended.

After the annual leave, Chen Wanrong rushed to the Military Equipment Supervisor. As soon as they met, everyone gave a little greeting and then went into intense work. Chen Wanrong called Ye Tianheng, Kou Yibing and others to discuss the opening of a university and expanding the Military Equipment Supervisor.

When starting a university, the Military Equipment Supervisor trained the students and accumulated some experience, which was just right for use. However, most of the people who came this time were boys, young and had to train for several years. This course had to change and started from the basics.

Chen Wanrong made some adjustments based on modern education, so that these boys should have good writing skills, of course they should not only teach poetry and books. It is easy to handle for them to have a math skills. The monks and their vocations are math masters, and it is not a problem to have him here.

Writing skills and mathematics are the foundation, and writing is a must-have for good scientific and technological talents, and no one has any objection.

A healthy body is a necessary condition. Chen Wanrong suggested that some basic body training for boys, but no one objected to this matter. Ye Tianheng was in a good health. He could still be busy in the military weapon surveillance at such an age. This is a living example. This matter is put on Sima Chengzhen’s master and apprentice.

Art can be used to motivate sentiments. People have a time to be tired. If they are tired, they can relax. This matter will be left to Wu Daozi.

While everyone was discussing, Yao Chong came. After a brief greeting, Yao Chong said his purpose: "I came to discuss with you the emperor's will to discuss the expansion of military weapon surveillance with you. Before talking about the main business, Yao Chong couldn't help it. If you want to say a few words, what your military weapon surveillance is doing now is related to the fate of the country and the future of China. You have to do your best. Yao Chong has thanked me here!"

"Yao Xiangyan is so serious, this is what we should do." Chen Wanrong and the others were busy and humble.

Yao Chong expanded a map. Chen Wanrong looked at it and outlined it with cinnabar on the map. It was obvious that the handwriting should have been written by Li Longji. Yao Chong pointed to the map and said, "This is a written by the emperor. There are twenty miles of land here and all are assigned to the military weapon surveillance."

"Twenty miles? Didn't it mean ten times? Isn't this twenty times?" Ye Tianheng was so surprised.

Yao Chong continued: "The emperor said that the current military weapon supervision will be expanded ten times first, and the rest will be expanded later. This place is close to the Longwu Army camp, and the security of the military weapon supervision will be left to the Longwu Army. Once there is something wrong, the Longwu Army can provide reinforcements nearby."

There are many secrets in the military weapon surveillance and must be strongly guarded. No matter how good this matter is to be suppressed by the Longwu Army, it will be gone.

Yao Chong pointed to the map and said, "There is an open space between Qinglongfang and Dunhuafang, which is about the size of a yard. I will allocate it to you to build a school building. It is close to Qujiang and has a good scenery. It can be used to study and enjoy the scenery. It is suitable for building a school building."

"The size of a house is not the same size as the Imperial College?" Liu Huaide shrank his mouth.
Chapter completed!
