Academy.

Unremarkable in front of the door.

A carriage came to a slow stop.

It stands to reason that all men in the Tang Dynasty should ride horses, and now Li Chengqian has also learned to ride horses.

But Li Chong felt that it was more comfortable to sit in the carriage.

And......

Riding a horse is too ostentatious, in case someone wants to be unfavorable to the prince, this prince riding a horse to the front, that is not the first to bear the brunt.

If there is a carriage, at least it can be topped.

"Teacher, it's here."

At the door, the guards guarding the door saw that His Royal Highness the Crown Prince had come down, and they also hurried to call the people inside to come out to greet him.

Li Zhong immediately called him to stop.

"No need to call it. It's a few steps away, so why bother. ”

"This ......"

The guard stopped and returned to stand guard in a huff.

Li re-looked at the plaque of the 'Academy of Sciences' at the door, and then looked at the inconspicuous words 'the people, the source of the country' hanging on the right.

Originally, I wanted to get something, 'the worries of the world first, and the joy of the world after the world'.

But this sentence did not conform to his truth, so he gave up directly and used such a simple sentence instead.

Of course, Li Chengqian also followed his teacher to look at the plaque and the words on the right.

Li Chong asked:

"Qian'er knows, why does the teacher use these five words?"

Li Chengqian thought for a while, and then said, "The teacher wants to say that this place is for the people?" ”

Li Chong smiled, "Almost." ”

Li Chengqian looked at the teacher who had already entered, and could only shake his head.

Indissoluble.

Why is it almost?

……

Soon.

The people inside were summoned and saw Li Chong.

"Sit down, don't be restrained, let me introduce myself first, my name is Li Chong, and I am now the president of this academy."

In fact, Datang prefers to use official titles such as Ling and Cheng.

But the word dean, in fact, should not be difficult to understand. That is to say, here he is the biggest, and he has the final say.

At first glance, these craftsmen are all craftsmen.

The hands are thick and calloused.

At first glance, it looks honest.

Li Chong said: "The purpose of this academy is actually to better serve the people. As we all know, people work hard to farm. Therefore, the Academy of Sciences is to prevent the people of Datang from working so hard. ”

Seven or eight people didn't know what Li Chong was talking about.

However, it doesn't matter if you don't understand.

Anyway...... Li Chong means that there is a program of action.

Next, they will slowly understand from the process of practice what they were called here for.

Li Zhong put the first target on the pedal reel.

Because of the pedal reeling car, Datang could have more silk, so that his concubines could wear beautiful and gorgeous clothes for his enjoyment.

Li Zhong then assigned tasks to these seven or eight people.

Of course, they will definitely be given a little hint as well.

Presumably, it is almost through the connecting rod to turn the original hand-cranked part into a pedal.

As for how this connecting rod is connected.

Then Li Chong doesn't know.

That's what they need to solve next.

At first glance, when they heard Li Chong's task, to be honest, everyone was a little confused.

For a while, I didn't know where to start.

In order to let them have a deeper understanding, Li Chong went to ask people to find a hand-cranked reeling cart, and then took some wooden sticks or something to facilitate their comparison.

And then slowly, they found a little bit of a feeling.

Actually, this shouldn't be difficult.

Li Chong felt that giving them a maximum of ten days and half a month would be enough.

After all......

Even the general concept map, he hung it directly on the screen.

Seven or eight people looked at the picture while studying it selflessly, and Li Chengqian could only say that he was also a little interested.

It's just that with his little head, I'm afraid it's hard to come up with.

Also, it's useless to just think about it, you have to do it yourself.

Therefore......

The next day.

Li Chong asked people to arrange everything they needed for them, and they all started to get busy.

Probably......

It's been about ten days.

This scaled-down version of the model seems to have been made.

Li Chong didn't bother with it, and let them continue to make the real thing.

And......

In order to improve efficiency, it is definitely necessary to be able to reel three bundles of silk at a time.

The craftsmen worked overtime.

Finally......

With the joint efforts of seven or eight people, it took more than 20 days to make this thing.

Li reeled on the reeling car and tested it himself.

Except that it feels a little unsmooth, and you can adjust it a little more, nothing else seems to be a problem.

So, some more comments were made.

Finally, a little more than a month later, the first pedal reeling bike was launched.

Therefore, the wisdom of the ancients is really not to be underestimated at all.

And then......

Li Zhong has to think about it next.

It is the question of how to benefit more people.

Li Zhong applied to Li Er for another house, and this house can be a little more casual.

It is directly placed in the southernmost two rows of Chang'an City.

It may not even be called a house.

It's a big pergola.

There is a roof on the top, which can shelter from the wind and rain, and in the middle, it is hollow.

In the hollow position, put dozens of pedal reels.

For the women of Chang'an City to come here to reel silk.

To be more precise, this may be a small experience hall.

When you run out of home, it's your turn to the next one.

You can't force someone else to stuff one thing, you have to let people use it at home, think it's really good, and then people will naturally go to the door and want to buy one.

Thereupon......

After using it for a winter, hundreds of pedal reels were accumulated, and then in the spring, once it was put into use, it immediately became the talk of all the people in the entire Chang'an City, especially the women among the people.

"There are free pedal reels in the south of the city."

"Reeling is free, too?"

"What does it mean that the reeling car is free?"

"What did you just say? Pedal reel? ”

The news spread from the south of the city, which was so barren that it could only be used to grow vegetables, all the way to the north of the city.

And a hundred pedal reels are obviously not enough.

However, some people actually just come to see the fun, by the way, get started.

Many women were instantly conquered by this kind of reeling car.

Moreover, there are people who come to compete with hand-cranked ones.

However, can the hand-cranked one be compared with the pedal, the hand-cranked one needs at least two people, when one person, the efficiency will be greatly reduced, after all, you have to add thread while shaking the car, but the pedal is different, one person can complete it very smoothly, the key, it can also reel three bundles at a time, which is more than the simple hand-reeling car in the homes of many people in the Tang Dynasty, I don't know how many times stronger.

So, some people who have money in the family began to inquire about how to customize the reeling car, how much the price is, and those who have no money at home also come over to see if they can use it.

In fact......

As long as there are people with carpentry skills, this reeling car can be imitated and copied, so Li Chong didn't think about selling this thing, so he could only go back and discuss it with Li Er.

Chang'an City counts a total of one million people, according to five people and one household, then Chang'an City is equivalent to 200,000 households.

Of course, the actual situation is certainly less than that.

Now, it depends on Li Ershe's reluctance to let his craftsmen come out to help and build tens of thousands of units.

However, if it is really created, how can it be distributed?

This is also a problem.

Or rather......

You can make an IOU first, make an appointment for the next year, or two years later, you can exchange the woven silk.

Rei main hall.

Li Er looked at Li Chong below, and he was also a little worried.
