With the help of the eldest princess of Ningyang, the two hundred armor soldiers were quickly in place.

The Mansion of the Duke of Ji and the Mansion of the Eldest Princess of Ningyang have a lot of subordinates and slaves, and there are also some relatives of some followers when the country was founded.

The two hundred people are all young adults selected from these people's families, one knows the roots, and the other is their own people, and the eldest princess of Ningyang can rest assured that they use these people.

Although I haven't received any systematic training, it's good to train while using it.

For this reason, Huo Jingzhi also made a special trip to find an old military brother who was idle at home in the past, and asked him to come over here to be the commander of these 200 people.

In terms of manpower, Huo Junyao hardly has to worry about anything.

For the next period of time, she was busy preparing for spring ploughing.

After understanding, she found that Yu Chao was still using a relatively primitive straight plow, and then she remembered the matter of making pig iron.

Originally, when she entered the palace, she wanted to ask for some pig iron, but a series of things that happened made this matter shelved.

Now that the situation is like this, it is not easy for her to speak.

After thinking about it, she came up with a solution.

"The slave has seen Grandpa Guo."

On the mansion of the eldest princess of Ningyang, the red sleeves respectfully greeted Ji Guogong, who came back from the lower office.

"Why did you go back to Beijing today? Is there something going on over there with Yaoyao? ”

Huo Jingzhi is still relatively familiar with the handmaidens around his daughter, and these people are all people around the eldest princess of Ningyang before.

"Returning to the country, it was the young lady who asked the slave maid to bring you something."

As she spoke, Red Sleeves took out a stack of drawings handed to her by Huo Junyao.

"This is a drawing made by the young lady, and it is called Quyuan Plow."

Then she recounted in detail some of the things she learned from Huo Junyao about Qu Yuanli.

After she finished speaking, she looked at Ji Guogong on the opposite side with a look of surprise on his face, and quickly turned over the result drawings carefully.

But soon his brow furrowed.

Don't look at him, although he is a scholar of the Ministry of Industry, he really doesn't know a lot about craftsmen, and at best, he has more contact than those who are officials in the same dynasty.

Compared with craftsmen or something, in the Yu Dynasty, it is a group of people who do not pay attention to it, and it can even be said that those civil officials in the court who claim to be scholars or something, and most of them have contempt for craftsmen.

When Huo Jingzhi didn't work as a secretary of the Ministry of Labor before, although he didn't despise craftsmen and the like, he also looked down on them.

This is not a dog looking down on people, but also arrogant, but more of a common normal psychology among readers.

Compared with in the eyes of readers, everything is inferior, only reading is high, let alone craftsmen, even if it is those generals who open up the territory, many readers look down on it in their hearts.

"Is this thing really as Yaoyao said?"

"The slave doesn't know, but if the young lady said so, it must not be wrong."

Red Sleeves is honest, she doesn't have a big bag, after all, she hasn't seen the specific role of this thing, but she still has 100% trust in Huo Junyao.

Huo Jingzhi also nodded after hearing this, of course he trusted his daughter.

"In that case, let the craftsman try it tomorrow."

Then he put the drawings away, then looked up and asked again; "Why did Yaoyao suddenly want to send something over?"

What kind of Quyuan plow is this, if it is really as powerful as Huo Junyao said, this is a great achievement, and it is even enough to go down in history.

Why did it suddenly send it out?

He is very aware of his daughter's dissatisfaction with the royal family, and if this thing is promoted by the Ministry of Industry, it will undoubtedly give most of the credit to the imperial court, or to the royal family.

If this thing is really that powerful, she will get out and publicize it herself, and the reputation she will get will not be low.

"Grandpa Guo, this thing needs to use pig iron, there is no iron on the Zhuangzi at present, Miss sent this thing to the imperial court, hoping to exchange it for some pig iron from the imperial court."

Hearing this, Huo Jingzhi was stunned for a moment, and then understood his daughter's plan.

Think about this is not bad, if it was put in the past, casually ask the emperor for two or three thousand catties of pig iron, I believe the emperor will be very happy, after all, the emperor has given it once, and it is five thousand catties.

But the current situation is different, he can feel that his daughter is alienated from the emperor, so it is naturally not good to ask for it directly.

Pig iron is a relatively important national resource, although the people also sell it privately, but the amount is not very large, and this is also a violation of the criminal law.

Especially these nobles, if they privately purchase these important materials, they will easily be attacked by people with intentions.

Therefore, it is best to take the clear path, and because of the change in the relationship, it is naturally the safest to adopt the method of exchanging one thing for another, and it will not give people a handle.

"How much pig iron is she going to want?"

"Miss said that it should be at least more than 3,000 catties, and I don't know how many slaves and maids there are."

Hearing this, Huo Jingzhi nodded and continued; "This matter is handed over to the national government, you go back and tell Yaoyao everything to rest assured."

Redsleeves replied and bowed.

The next day, early in the morning, Huo Jingzhi took the drawings to the Ministry of Engineering and found a few craftsmen, but he got the first Quyuan plow out in the morning.

Then I directly found someone to try it, and the results I got were really the same as Huo Junyao said.

Not to mention the need for more effort, there is no need for so many ploughing cattle.

In the past, the straight plough needed two ploughing oxen, and the efficiency was still very low, but now this curved plough only needs one person and one ox, and the efficiency is much faster than the straight plow.

Even if there is no ploughing ox, even if it is pulled by manpower, it can be used, although the speed is slower than that of cattle, but compared with the original method of ploughing the land before, it is much more powerful.

The thing has been made and has been verified, Huo Jingzhi is not delaying, and immediately asked people to take Qu Yuan plough and go straight to the palace study.

At this time, in the imperial study, Emperor Zhaowu was reviewing the folds, and the spring ploughing was imminent, and there were many things that needed to be dealt with in various places.

"Your Majesty, Ji Guogong asks to see you."

"Respectful of it? Let him in. ”

Not long after, Ji Guogong walked in from outside and respectfully bowed to him.

"Is there anything important that Jingzhi came to see me at this time?"

Hearing this, Huo Jingzhi didn't talk nonsense, and directly told Qu Yuanli in detail.

After listening to this, Emperor Zhaowu's eyes lit up, as an emperor, he naturally knew very well what this series of data represented.

Farming civilization, the most important thing is this farming, this curved plow is more than one or two times more efficient than the original straight plow, what this represents, he couldn't be clearer.

"Is it really such a fetish?"

Although he knew that Huo Jingzhi had always been steady, and if he could report here, he must have verified it, but Emperor Zhaowu was still a little too surprised to believe it.

"Back to Your Majesty, the minister has personally verified it, and it is true."
