Thousands of palace maids are a bit exaggerated, and in the past two years, Li Shimin has also given many palace maids to the ministers, and some of the others have also been dismissed.

Facing Li Yuanjing, who suddenly asked him to be a palace maid, Li Shimin didn't know what to do for a while.

I wanted to deal with the past, but I couldn't stand Li Yuanjing's serious request that the palace maids must be taken away, and the number of people should not be less than five hundred.

In desperation, Li Shimin had no choice but to let Empress Changsun select and transfer three hundred palace maids from the palace.

Although it was far from meeting expectations, it was better than nothing, Li Yuanjing left the palace in a hurry, and these palace maids would naturally be sent to the imperial village.

And Li Shimin, who sent Li Yuanjing away, was in no mood to go to work anymore.

"Guanyin, what did you say the prince has been doing lately?" Li Shimin, who had no intention of working, came directly to the main hall and asked with a melancholy face.

"I heard that the concubine is familiar with farming, and the prince returned to the palace a few days ago, and he is not as impetuous as before!" Empress Eldest Sun smiled and said euphemistically.

"Humph!" Li Shimin snorted coldly, of course he knew that Li Chengqian returned to the palace a few days ago, and this kid didn't come to report to his father when he returned to the palace, if he was really busy farming, it would matter, thinking of this, Li Shimin was furious: "You don't have to excuse him, what virtue the prince has, I know it clearly in my heart." ”

Li Shimin's original intention was to let Li Chengqian personally experience the hardships of farming, to understand the impact of advanced agricultural tools, and to let him know in his heart what farming is all about and what decisions the rulers make that are beneficial to the peasants and not to the peasants.

If all the people are safe, the world will be safe!

Li Shimin's original intention was to let Li Chengqian understand this truth, but the facts gave Li Shimin a slap in the face.

Li Chengqian is not happy with each other in Huangzhuang, Li Yuanjing is also lazy to care about him, this kid does not say that he does it himself, he goes through the motions like a monk hitting the bell every day, and he still asks his subordinates to find the peasants to understand, and then assembles them into a book, and he memorizes them to deal with errands.

Although Li Shimin didn't say anything, and he didn't let people teach Li Chengqian a lesson, Li Chengqian's behavior made him deeply disappointed.

"Bring the prince back!" Li Shimin sighed deeply, it was pointless to continue to keep him in Huangzhuang.

One is not on the road when he is killed, and the other is as cunning as a loach, these two people faintly gave Li Shimin a little headache.

"Yuan Jing mentioned to me again that he was going to start the imperial examination, what do you think?"

"The concubine's opinion is the same as that of the second brother!" Empress Eldest Sun smiled and answered Li Shimin's question with a conventional routine.

"But this time I'm moved!" Li Shimin stared directly at Empress Changsun.

"The concubine will always support the second brother!" Empress Eldest Sun still didn't give a clear answer, she knew very well what kind of answer Li Shimin wanted, but she couldn't give this answer herself.

Eldest Sun Wuji looked at Empress Eldest Sun helplessly, and shook his head with a smile.

This is also the normal state of their husband and wife, what can make their hearts move, it must prove that it is beneficial to Datang, but the resistance encountered must not be small, the queen will not express her position on this kind of thing, but her position is very firm, and her attitude is her attitude.

Unless it is proved that she is really wrong, at this time, Empress Changsun will stand up and reprimand herself and wake herself up.

……

Things in Chang'an are like that, everything that should be done has been done, and I can't wait for my eyes to knock on the door to find death.

But Li Yuanjing didn't think anyone would be so stupid.

He then had to personally supervise the construction of the looms, which he would be able to build to 5,000 in a short time.

Of course, this task is mainly to replace Yang Li, and Yang Li's first task is to carry out a new transformation of the loom.

Otherwise, 200 craftsmen will be transferred directly from the palace, and according to the assembly line production process, the weaving workshop can be expanded to a scale of 5,000 units in ten days.

Yang Li's research task has reached a bottleneck, and the looms used today have been modified to the extreme, and there is little value in making small changes.

According to Li Yuanjing's requirements, Yang Li put the focus on a new direction, that is, no need to manually control the shuttle, Yang Li thought of using water power, using the runner, but the effect is not good, basically every five times at least one or two will tear the line off, the conversion efficiency is reduced.

Regarding the principle, Li Yuanjing didn't understand it, so he could only helplessly hand over this arduous task to Yang Li to solve by himself.

"It's done...... It became ...... I became ......"

Just when the two of them were at a loss, the eldest grandson rushed into the courtyard excitedly.

The palace was still under construction, but the first weaving and iron-smelting workshops were the first to be built, and the two courtyards were close to each other, separated only by a courtyard wall.

In the courtyard of the iron-smelting workshop next door, a blast furnace about 10 meters high is erected, and smoke is billowing from above.

After studying for a few months, Changsun Jun finally saw his results, and even in order to be able to do it as soon as possible, Changsun Wuji personally opened the back door and quietly recruited five experienced old blacksmiths for Changsun Jun to help.

"Let's go, let's take a look, and change our brains by the way!" Li Yuanjing nodded, he was not surprised by the success of the eldest grandson, if he did not succeed, it would be called an accident.

The general layout of the blast furnace has already been told to him, and what Changsun Jun needs to do is only to test and improve in local aspects, and there are five experienced old blacksmiths by his side, and the quality of the iron he has trained is naturally checked for him as soon as possible.

Yang nodded heavily, but in his heart it was as if a mountain was pressing him out of breath.

Even the little kid Changsun Jun has succeeded, but he is still spinning in place, and he is engaged in a loom, and Changsun Jun is engaged in iron, in Yang Li's opinion, the difficulty of iron is much higher than that of a loom.

But the reality is that boring, always like to play with people.

"What's going on now?" On the way to the next door, Li Yuanjing couldn't help but ask.

Although I haven't paid much attention to my neighbor during this time, I haven't relaxed on the technical improvement of iron smelting.

Once this technology is maturely used, what does it mean? It doesn't take much thought to do so.

Although Datang's iron-smelting technology is not backward, it is definitely not much different from the advanced, and the efficiency is extremely low.

Of course, this is the case for the whole world at the moment.

"This furnace has been burning all day, constantly throwing ore into it, and now it has produced at least three hundred catties of iron, and the craftsman estimates that this furnace can produce almost one thousand catties so far, one and a half thousand catties a day, and the efficiency has increased by at least ten times!" Eldest Sun Jun said excitedly.

He also knew what the improvement of iron-smelting technology meant, which was no longer something that could be dismissed by a county uncle.

Ten times?

Li Yuanjing smiled, the birth of a blast furnace is only ten times more efficient than the ancient method?
