Li Chengqian recalled the records about the quyuan plough in his head, so he knew that in history, the application and popularization of the quyuan plough greatly improved labor productivity and the quality of cultivated land.

The invention of the Quyuan plough opened a new page in the history of traditional agricultural tools, so that in the future era, unless there was war, there was little famine.

However, now the plough of the Tang Dynasty is not only a straight plow, but also a wooden plow, mainly because of the backwardness of iron-smelting technology.

It has been like this for thousands of years, and no one has changed it. It's not that they don't change, it's that people are running around for food and clothing, so how can they have time to improve?

So, it has been dragged until the middle of the Tang Dynasty.

Therefore, Li Chengqian wanted to change it, and what he asked Wei Chi Jingde to do was an iron curved plow and plow shovel.

Because at this time, iron can already be produced in a short period of time, with high quality and high yield. The main thing is that it is close to the presence of steel, so durability and corrosion resistance will also be upgraded to a notch.

Therefore, it is better to use these iron as ploughs and shovels.

Wei Chi Jingde did not disappoint Li Chengqian, they built again and again, without rest.

Until the evening, Wei Chi Jingde hurriedly brought the plough shovel, and at this time there were already many carpenters waiting in the East Palace.

All they have to do is to plow the frame, if the whole curved plough is made of iron, the first is the high price, the second is that the weight is really unbearable, and the maintenance is not convenient, but the use of good wood is different.

Moreover, with the current iron ore production, more Quyuan ploughs can be made, and if it is extended to the entire Datang, then the future can be expected.

"His Royal Highness the Crown Prince, this ......"

Wei Chi Jingde was very puzzled by what Li Chengqian was going to do.

It was also because he was not present at the feast.

"This king wants to change the whole status quo of labor! So that people can farm more efficiently! ”

Li Chengqian looked at the plough shovel as he spoke, and the quality was very high-grade.

And there is no superfluity in the whole shape.

"His Royal Highness the Crown Prince can take a long-term view, which is what those of us who are courtiers have to learn."

It's not that Wei Chi Jingde is patting on the back, but he's telling the truth.

Li Chengqian's six-day tenure can be said to have done something very unbelievable.

No matter which one it is, it is to change the direction of Datang in the future.

And Li Chengqian is not proud of his achievements, because there is nothing worth showing off.

He said

"This is what you should do as a prince! This is done for the common people of the world. ”

Wei Chi Jingde nodded yes.

"Yes! His Royal Highness the Crown Prince is right! ”

"Wu Guogong, come and get this thing inside!"

After Li Chengqian finished speaking, he walked to the front, and Wei Chi Jingde followed him.

And when they reached the backyard, there were already a dozen carpenters working there.

There was a strangely shaped thing parked in front of them.

"How's it going?"

Li Chengqian asked as soon as he came.

Someone responded, "Your Royal Highness the Prince, the shelf is still a little bit away!" ”

"Good! Wu Guogong, give this thing to them and let them install it! ”

Wei Chi Jingde was still at a loss, because he didn't know what this was for, a strange, curvaceous shelf, and with this shovel, what was it for?

He didn't know, and he couldn't possibly know.

Wei Chi Jingde took the plough and shoveled it to the carpenter.

"His Royal Highness the Crown Prince, this ......"

"Just look at it!"

"Yes!"

There was a lot of noise in the entire East Palace, and more than a dozen people were circling around a strangely shaped thing.

Finally, the carpenters came to talk to Li Chengqian.

"His Royal Highness the Prince, it's already assembled."

Afterwards, these people carried a brand-new curved plough in front of Li Chengqian.

Only then did Captain Chi Jingde find out what was going on.

"This ......"

"Yes, this is what this king has made. Come on, try a cow! ”

At this time, Guan Lishi said, "Your Royal Highness the Prince, there are no cattle in the East Palace, and it is so late, there is nowhere to find cattle." ”

It seems that if you want to try, it is really impossible.

At this time, Xue Rengui came out and said, "His Royal Highness the Prince, let the villain give it a try!" ”

Everyone focused their eyes on Xue Rengui.

This guy is as strong as an ox, and he can have a strong confrontation with the ox, and if he can pull the zigzag plow, then the ox must have it.

In terms of strength, Xue Rengui is stronger than a cow, but in terms of endurance, he may not be as strong as a cow.

But it wasn't for Xue Rengui to pull the plow.

"Okay, I'm tired!"

After Xue Rengui saluted, he pulled up the rope of the curved plow.

Ready.

"Wu Guogong, you have to carry this plow!"

Li Chengqian's stature is too small to control, otherwise it will definitely be more interesting if he comes.

"Yes!"

People have seen a lot of oxen pulling the curved plow, but this person may have seen it for the first time.

Wei Chi Jingde has planted the field, and he quickly mastered it!

In the end, people's eyes were on Xue Rengui.

"Up!"

Xue Rengui shouted.

The plough began to move, and sank deep into the dirt of the backyard.

Rise!

As Xue Rengui's voice fell, the Quyuan plow continued to drive forward, and what it left behind was a row of dirt that had been turned over.

It is not very clear that it is dark at the moment, but Li Chengqian thinks the effect is not bad. I'm sure I'll be able to put on a good show tomorrow.

From this point of view, Wei Chi Jingde and the major carpenters were dumbfounded.

"His Royal Highness the Crown Prince, this ...... This Xue Rengui is too strong! ”

Wei Chi Jingde is interested in Xue Rengui's strength.

This afterlife is really terrifying and terrifying.

But Li Chengqian smiled and said, "He's right, but everything still lies in this Quyuan plow, I believe that Wu Guogong must also be able to pull it." ”

"So...... Can I? ”

"Yes! Well, don't talk about everything tonight, you know? ”

Li Chengqian didn't give him a chance to try, after all, it was too late.

Everyone should be, in this way, just wait for tomorrow to dawn, and then you can start performing.

So Li Chengqian sent an order to go to the court in the East Palace tomorrow morning! Make no mistake!

This is unique, and the early dynasties have come to the East Palace.

This will inevitably make people slander, but Li Chengqian doesn't care, and all opposing voices will be silent under the refutation there.

And tomorrow is also the last day to take charge of Datang, he has not enjoyed it in the past few days, but he has also benefited a lot, so that Wang Cui and his family are much more honest, and their own Fengtang Dynasty business house is getting bigger and bigger, and they benefit from it.

As for the task of people's livelihood, it can be completed no matter where you are. It doesn't matter if the people are in charge of Datang or not, and Datang is not their own in the future?

Having said that, being an emperor is not an idle matter, and now that he is in his prime of life, he should go to have more fun, and don't be trapped in this palace all day long, life is too boring.
