Dongping Palace.

A total of more than twenty people stood together, looking at several cultivated fields in front of them.

The mansion given to Cao Xi by the emperor covers a large area, but this large area of land has been turned into a vegetable garden by them.

The arable land here is divided into several different types, in which the crops, seeds, including irrigation and weeding are exactly the same.

But different places use different fertilizers, and of course, there are places where fertilizers are not used.

Through such experiments, we can see if the fertilizer they make is effective.

This experiment has been going on for some time.

In order to see results faster, they applied fertilizer directly to the vegetables.

Cao Chao was also standing in the middle of these people at the moment, listening to the official in charge of taking care of these vegetables explaining the results of different types of cultivated land to everyone with great interest.

"This is the No. B field, and the No. B fertilizer used is also made by the king, and it is currently growing the most amazingly, and it grows better than all the cultivated land, everyone see."

This official was sent by Lu Zhi, and I heard that he was also from a big family.

It is said that this person is not good at fame and has never been a official, but later Lu Zhi heard about his reputation and talent, so he sent someone to summon him to be an official.

At that time, such recommendations had not been completely abolished.

As a result, the man did not want to go, so he ran somewhere else.

But later, there was some turmoil in the world, that is, when He Zeng had just become the ruler, those who were unwilling to appear in the temple were considered dissatisfied with His Majesty, and they were all arrested and questioned.

This man was very frightened, and hurriedly came to Lu Zhi to plead guilty, Lu Zhi forgave him for his original rudeness, and after examining his talents, he felt that he was the capable person that the household lacked, so he left him behind.

But this person's ability in governing government is really sparse, and for so many years, he has achieved nothing in government affairs, and he is completely a tool in the household department.

The official position is getting lower and lower, and now they are all thrown over to take charge of the test field.

However, Cao Chao found that when this person did the control test, the logic was very clear, and when he talked about various experimental fields, the head of the analysis was the Tao.

It doesn't look like the kind of person who is incompetent and incompetent.

The rest of the people's minds were on those test fields, especially Cao Xi, whose mouth was about to smile crookedly at the moment.

Compared with the soil fertilizer in the past, this chemical fertilizer is really exaggerated now! The difference between the two is so great that it's hard to compare.

Even the chemical fertilizer made at the current level is enough to beat the fertilizer of the past in all aspects.

Just look at the growth of the vegetables and you can see how terrible it is.

King Dongping really couldn't help it at the moment.

This recipe is actually real!!

Now he can be regarded as a famous person in history, making such a thing, after death, it is enough to be a god and receive incense, right?

It's hard for him to say how happy and excited he is at the moment.

He didn't even rely on the rest of the alchemists, he just asked Huangfu Mi to give him a start, and he successfully refined a variety of fertilizers.

Of course, they didn't just refine one, although the emperor gave the formula, but the formula was not perfect.

It is a very shameless behavior to only talk about the ingredients and not the complete proportion, the specific proportion can only rely on the test, they have configured a lot of copies, and the effect of No. B fertilizer is the most significant.

Cao Chao looked calm, as if he had known that the recipe was real.

He smiled and said to Cao Xi: "This time the king of Dongping has made a great contribution." ”

"Don't dare, if it weren't for His Majesty's formula, how could the minister succeed in refining?"

Cao Chao smiled, and then said to Zhang Hua on the side: "Reward Dongping Wang Baijin, gorgeous clothes, and horses." ”

"The rest of the people shall be rewarded with twenty gold each."

Zhang Hua hurriedly received the order.

Everyone bowed and thanked.

Cao Chao looked at everyone seriously, and continued: "You have worked hard, this is what you deserve, in addition, I am going to prepare a mansion for each of you, stay in Luoyang in the future, don't go back." ”

Cao Chao looked at the people in front of him.

Of course, these people are real medical scientists, and they refine things to cure diseases.

However, among these people, there is also a kind of special desperate scatter master, who is specially made and sold to Pei Xiu and them to eat.

In any case, Cao Chao wants to keep these guys in Luoyang, even if it doesn't help the chemical fertilizer, just don't stay in the local area and harm people.

Moreover, these chemists still have a lot to show their talents in the future, such as gunpowder.

The gunpowder was discovered by this group of people, and now it is time for them to discover it.

Everyone was very happy about this.

They didn't linger any longer, and hurried to their respective laboratories to get busy.

Cao Xi stayed by Cao Chao's side.

"Your Majesty, it's not an exaggeration to say that this recipe is a little stone into gold, shouldn't you send someone to keep an eye on these people, so that they can't tell the outside world?"

Cao Xi's eyes narrowed, all he could see was how valuable and important this recipe was.

This is an artifact that can increase grain production.

Cao Chao laughed, "It doesn't have to be like this, why should this recipe be hidden?" I can't wait for them to talk about it, to go around it. ”

When Cao Xi heard him say this, he naturally just smiled and nodded, saying that His Majesty was wise.

Cao Chao was a little interested in the official at the moment.

He asked Cao Xi to continue to work on himself, and he called the official from Fang Cai and asked him to take him to continue to visit the experimental field.

The official's name is Liu Hui.

He looks very clever.

And the reason why Cao Chao is interested in him is because of his other identity.

The first mathematician of the Wei and Jin dynasties.

Of course, it cannot be regarded as the Northern and Southern Dynasties, only limited to the Wei and Jin dynasties.

The first brother of mathematics in the Northern and Southern Dynasties once commented on Liu Hui and believed that Liu Hui was the top among many mathematicians in the Wei and Jin dynasties.

This Liu Hui has this work, "Nine Chapters of Arithmetic Notes", others are annotating Spring and Autumn Rite poems, this old brother is more powerful, he is annotating nine chapters of arithmetic.

And he did quite well, he sorted out the ancient Chinese mathematical system, and laid the theoretical foundation of the ancient mathematical system.

He inherited this system and became a veritable master of mathematics.

And when it comes to specific achievements, there are too many to say.

Listening to Liu Hui taking himself to visit many experimental fields very seriously, Cao Chao couldn't help but ask: "Liu Jun, I heard that you are the best math on weekdays, study all day long, don't like to go out, and don't want to be an official, how can you be in charge of some farming things here today?" ”

Liu Hui's eyes widened.

Of course, although Liu Hui at this time cannot be said to be a no-name junior, he is really not a domestic person.

He just started to note nine chapters of arithmetic, and he didn't even finish it!!

It belongs to the time when it is just beginning to rise.

Liu Hui couldn't figure out how this emperor knew about himself?

Looking at his stunned expression, Cao Chao asked, "Isn't Liu Jun going to make notes for the nine chapters of arithmetic?" ”

Hearing this, Liu Hui was even more scared.

He only decided to make notes for the nine chapters of arithmetic half a month ago, and now it has just begun, and he has been in the mansion all along, and even his wife doesn't know about it

He swallowed, "That's right. ”

Seeing his frightened appearance, Cao Chao suddenly understood that he probably just started to have this idea.

Cao Chao asked about the process again.

Liu Hui talked about the current progress, and sure enough, it had just begun.

During the conversation, Liu Hui became more and more excited the more he talked.

Most people think that they can beat all the mathematicians of that time when they return to ancient times, and this is the case on average, but if you compare with the scholars, in fact, these scholars who have read the Five Classics also have to know the numbers, and their mathematical ability is not bad.

Mathematics in ancient China is not a subject that is not taken seriously, on the contrary, it has been developing rapidly, and every dynasty can come up with representative mathematics, even if it is a very unpopular and short-lived dynasty.

Even if it is Wu Guo, there is a great mathematician Wang Fan.

But it's a pity that because this guy didn't drink well, he was executed by Sun Hao and died young.

Cao Chao listened carefully to the mathematician's story, sure enough, Ma Jun is like this, and Liu Hui is the same, when it comes to their majors, they are not so restrained, and their speed of speech has become much faster.

Cao Chao listened to his words very carefully.

"Yes, yes, you can leave the things here to someone else to do, and you can make your annotations with peace of mind first."

"I see, you are a person who can go to Taixue to teach mathematics, and it is really a bit condescending to hold the official position you have now."

Just like taking care of the experimental field, the household department can bring a large number of people to do it at any time.

But the person who commented on the arithmetic in the ninth chapter is now the only one left in the whole world.

Cao Chao is a person who loves only his life.

Liu Hui could feel the importance that the emperor attached to him, and he was also excited.

But this is a rare kind of minister, he doesn't care much about fame and fortune, he just likes mathematics very much, and his character is suitable for going to Taixue to be a doctor.

Cao Chao finally got into the carriage back.

Sitting in the carriage, Zhang Hua told him about Wang Chang and Liu Yuan.

Cao Chao couldn't help but sneer.

"The support and promotion of fellow villagers among the big clans, I thought it was a thing of the past, but I didn't expect it to be like this now."

Zhang Hua said in a low voice: "I heard that some ministers have begun to look for the prince and want the prince to come forward."

"It is impossible for Wang Chang to come forward."

Cao Chao shook his head, unwilling to talk about this matter anymore, and asked very dryly: "Is there anything else?" ”

"Yes, Your Majesty, there are two more small countries in the Western Regions that have contacted the Changshi Mansion, and they are willing to follow the example of King Shanshan and take the country as a county!"

"Oh? That's a good thing. ”

Today's Shazhou has another Shanshan County, one north and one south in the Western Regions, each with a county, which is also a good start.

I heard that Changshi is putting pressure on the Qiuzi Kingdom and the Yanqi Kingdom, hoping that they can follow Shanshan County as soon as possible, but it is not so easy.

After all, these two countries are relatively powerful.

And Zhuge Xu has also set off from Luoyang, presumably he will soon be able to reach the Western Regions
