Datang: Time travel in two months, wait online, hurry up!

At least in this discussion, Changsun Wuji didn't want to have any sense of participation.

This is the fate of playing against him when he has a big tailwind!

Just as Li Ke thought, after Changsun Wuji heard his apology, his face became even uglier.

The winner apologizes to the loser, it will only make people more disgusting!

"Ha ha!"

And Cheng Yaojin and Yu Chigong couldn't help laughing out loud after hearing Li Shimin tell the eldest grandson Wuji to talk less!

"What are you laughing at?"

Changsun Wuji stared at the two of them coldly.

"It's nothing, I just suddenly thought of something funny."

"5.8 is right, we guarantee that it has absolutely nothing to do with Zhao Guogong!"

Cheng Yaojin and Yu Chigong had playful expressions on their faces.

After hearing the words of these two people, Changsun Wuji's face became even darker!

"Ke'er, are those two things you just said true?"

Li Shimin couldn't wait to ask Li Ke.

He really couldn't imagine the use of those two things Li Ke said.

But since Li Ke said it, and Li Ke is not the kind of person who would talk big about him.

"I want to report to my father, I assure you that everything I said is true and there is no exaggeration!"

Li Ke's expression was indifferent, and his tone was full of confidence!

Feeling his self-confidence, Li Shimin seemed to have gained some confidence.

"Then when will you be able to get the Quyuanli and the barrel cart you mentioned?"

Li Shimin had to be in a hurry, spring plowing was about to begin, and if these two things could be produced earlier, it would be of great help to spring plowing!

"Father, my son has already asked craftsmen to make some in the palace. I think we can experiment with the effect first!"

Li Ke smiled slightly and suggested to Li Shimin.

A few days ago, he recruited all the craftsmen from Li Yin's house, just to build something.

Among them, including Quyuan plow and bobbin cart!

PS: Seventh more! .

Chapter 69 Served as the Minister of Industry!Meet Li Zhi for the first time!

Originally, he was planning to use it for the next seed production.

Therefore, some people have built some curved plows and bobbins in advance to facilitate the next plan.

After all, turning seeds into seedlings also requires plowing and irrigation.

Unexpectedly, Li Shimin and the ministers happened to discuss spring plowing today by mistake.

So he simply took out the Quyuanli and the bobbin cart and talked about it.

Anyway, sooner or later it will be taken out for everyone to use, and now it can be used for meritorious service, so of course he will not miss it.

"Already figured it out?"

Hearing that it has been made, Li Shimin was overjoyed immediately: "Okay, let's use it now and see the effect!"

As expected of Li Shimin, with this vigorous style, as soon as he heard that there was a finished product, he immediately went to the field to see the effect of the Quyuan plow and the bobbin cart for himself!

"Go directly to Huangzhuang, Ke'er, let someone go back and bring the things over!"

Li Shimin thought about it and decided to conduct experiments in Huangzhuang.

Huangzhuang is actually the land of the royal family, and there are special people in charge of farming.

"Yes!"

Li Ke nodded, and then ordered a guard of the palace who followed him to escort Qu Yuanli and the barrel car to Huangzhuang after returning.

And Li Ke followed Li Shimin and his party and went straight to Huangzhuang.

Fortunately, all the ministers came to the palace in the carriages of the various houses.

So everyone boarded their carriages directly at the gate of the palace, and a group of carriages drove towards Huangzhuang mightily.

Not long after, the carriage arrived near a fertile field on the outskirts of Chang'an City.

Li Ke got out of the carriage, and found that this was an endless fertile field, and some farmers were already working in the field, preparing for spring plowing.

And next to these good fields, there is a river with sufficient water, which is absolutely more than enough to supply these good fields with water.

Moreover, as expected of the royal family's Huangzhuang, the ditches here are neatly dug, and the water can circulate very well.

But he quickly realized that this is Huangzhuang!

Can the ditches be dug well?

If the digging is not good, it is estimated that the grass on the grave head is an inch high.

This is an imperial society!

It's not the situation in modern times. If the modern tofu dregs project appeared in the imperial power society, no amount of heads would be enough to cut off!

The Ming Dynasty was even more exaggerated. Every brick used to build the city wall was engraved with the name of the burner!

Once there is a problem with any brick, go directly to the burner, and cut it down without a word!

This also led to the fact that even when Li Ke traveled to the Chang'an city wall before, he saw that the bricks had not broken after hundreds of years.

Not long after, the guards of King Wu's Mansion brought a Quyuanli and the parts of the bobbin cart.

Because the bobbin is too big and unlucky, it would be more convenient to ship the parts directly for assembly.

"This is Qu Yuanli?"

Soon, Li Shimin and others saw the legendary Qu Yuanli!

They found that the curved shaft plow is actually similar to the common straight shaft plow in structure, but the design is slightly different.

"It's just that this is different, can the speed and effect of farming be greatly improved?"

After seeing the ordinary Qu Yuanli, Li Shimin's heart was not as low as before.

Not only him, but other ministers looked at Qu Yuanli with suspicion.

Since Changsun Wuji was 'muted', he really wanted to say something, but he hesitated and held back.

But Li Ke could tell from the look in his eyes that he definitely had no good intentions.

"Father only needs to let the two of them use the straight plow and the curved plow to plow the land together, so that they can see the plowing speed and effect of the two plows at a glance!"

Practice is the only criterion for testing truth, Li Ke directly asked people to conduct experiments!

Real gold is not afraid of fire, Quyuanli definitely has a huge advantage over Zhiyuanli!

"Yes, this method is good!"

Hearing this, Li Shimin's eyes lit up immediately.

Is Qu Yuanli as good as Li Ke said, just compare and you will know!

Li Shimin immediately ordered someone to bring two oxen, and then one of them would use a straight plow and the other a curved plow.

In fact, the methods of use are similar. After Li Ke briefly introduced it, the farmer understood how to use it.

"start!"

Li Ke called out to start, and then the two farmers drove the cattle and started to move forward.

Soon, the plow went deep into the ground, and with the pulling of the oxen, the plowing began.

It's just that the cow using the Quyuan plow was obviously faster, and it seemed to be very easy!

Moreover, the soil dug out by the Qu Yuanli is very deep, much deeper than that of the Zhi Yuanli.

Not only is it faster in speed, but it needs to turn around when plowing to the edge of the field, and the Quyuan plow turned around easily.

But it is too difficult for Zhiyuan plow to turn around, and it takes time and effort.

Seeing this scene, Li Shimin and others were already shocked!

It turns out that such a small change can have such a huge impact!

Even if they only plowed for a while now, they have clearly seen the advantages of Qu Yuanli!

Compared with Zhiyuanli, Quyuanli is indeed much easier to use!

Soon, Qu Yuanli plowed a piece of land.

After plowing, everyone noticed that the cattle didn't seem to be working hard, and they were quite energetic.

After a while, Zhiyuanli plowed the land.

Not only that, but the farm ox obviously used up a lot of physical strength, and the walking pace was obviously not as easy as that of the previous farm ox.

Moreover, the gasping sound was extraordinarily heavy, obviously it was a bit too much physical exertion.

"Report to Your Majesty, what kind of plow is this, the old man has never used such an easy-to-use plow!"

A farmer looked at the plow he was using just now with surprise on his face, and his eyes were full of love.

How much time and effort would be saved if such a plow could be used to plow the land!

"This is Quyuanli."

Li Shimin was very happy at this time, and he also thought about chatting with the old man.

He witnessed Qu Yuanli's speed and effect with his own eyes, and he was completely at ease.

"Ke'er, can you explain why?"

However, Li Shimin still doesn't understand why such a huge change can be produced by just making a few changes to the structure.

"Returning to father, the shaft of the straight shaft plow is straight and long. It will be very laborious for the ox to pull it, and it is not flexible enough. It will be difficult to turn its head."

"I was wondering if I could make the plow more labor-saving and flexible, so I changed the straight shaft to a curved shaft and a short shaft, and installed a free-rotating plow disc on the shaft head."

"In this way, compared with the straight shaft plow, the plow frame of the curved shaft plow is lighter and smaller. At the same time, it is more flexible to turn and turn, and it saves manpower and animal power."

Li Ke explained the truth to Li Shimin and the ministers as simply as possible.

Since what Li Ke said was very popular, and Quyuanli and Zhiyuanli were placed next to each other, everyone basically understood the truth after listening to it and comparing it with real objects.

"I see!"

Li Shimin suddenly realized.

The other ministers also had similar expressions to Li Shimin's, and they all had the same expressions as before.

"Father, in fact, the structural design of these things is not all magic tricks, many things can greatly help productivity."

Li Ke took the opportunity to instill in Li Shimin strange skills and ingenuity, not all low-end things, many technologies can bring huge productivity to society!

"What you said makes sense."

Li Shimin nodded, as if he agreed with his statement.

No way, no approval!

Quyuanli in front of him is right there!

This living example is right in front of you, and Li Shimin is not blind.

Changsun Wuji was also shocked when he saw Qu Yuanli's speed!

But he has also learned to be smart, knowing that now is Li Ke's tailwind, and he can't go up to give away the head.

So I kept watching honestly from the sidelines, and at the same time raised Li Ke's threat level to an extremely high level again in my heart!

"That's right, Quyuanli is indeed as magical as you said, what about the cart?"

Li Shimin immediately thought of irrigation with bobbins, is it just like what Li Ke said?

"Father, please wait a moment!"
