After reading the printing of the test papers, in the afternoon, I continued to walk roughly with Qian Yongren and Tao An through the various venues that were about to be used as examination rooms, and the other two went to be busy, while Zhu Yuan came to a courtyard at the northwest end of Jinling University located on the halfway of Hongshan Mountain.

A large area here has been carved out by Zhu Yuan, and it is planned to be built into various laboratories.

It involves physics, chemistry, etc.

The relatively remote corner is also for the sake of confidentiality, which is a plan agreed with Lao Zhu before, such as chemistry majors, students must carefully choose and formulate strict confidentiality rules.

All kinds of technologies at this stage, in Zhu Yuan's view, are actually very primitive.

However, this is done in order to set rules in advance and establish the idea of technical secrecy.

Regarding the issue of rules, Zhu Yuan also discussed with Lao Zhu in private, because of the "Book from Heaven", this time, Lao Zhu does not want his children and grandchildren to abide by various rules so rigidly in the future.

Of course, Zhu Yuan's attitude is the same, and even suggested that Lao Zhu write 'flowing water is not rotten, and the household hub is not beetle' in the ancestral training.

If there is still an ancestral precept this time.

It's just that some rules can't be rigid, and some rules must also be set to death.

For example, the whole people pay taxes.

At this point, Lao Zhu has already stated that in the future, even if it is a royal family, it must pay taxes.

This is a matter of national capital.

However, on the other hand, while the tax rate must be paid by the whole people, the tax rate should not be too rigid, and when it needs to be raised, it must be raised, and when it needs to be reduced or even exempted, of course, it must be exempted.

As for the scale, it is based on future national fiscal situation and economic growth data.

In general, it will take a long time to explore and finally set up a relatively complete system.

However, there are some fundamental references, and the premise of everything is still Zhu Yuan's 'economic science', or 'production' and 'distribution'.

This time, Zhu Yuan will also make some things clear in advance, for example, in the future, all economic theories that violate the principles of "production" and "distribution" in the "science of economics" need to be strictly vigilant and even banned.

Because Zhu Yuan knows very well what the meaning behind many simple or complex economic theories in his previous life is.

For example, the free market.

The one that was once praised to the sky gradually proved that it seemed to be ...... Not quite right.

Those who really obey are either deceived and lame, or those who pretend to be deceived and lame, and the result is that they are harvested.

There is no 'market' in the normal 'market'.

From Zhu Yuan's personal analysis of 'economics', the corresponding theory may play a role in stimulating 'production' in the early stage of the development of a 'market', but once it enters the mature period, it is too free and forms a monopoly, which will inevitably inhibit 'production' in turn, because too strong productivity will impact profits, and only by maintaining a certain output can the benefits be maximized.

On the other hand, it will inevitably lead to more and more extreme 'distribution' imbalances, which in another word, are the gap between the rich and the poor.

Once a businessman, Zhu Yuan absolutely welcomed this.

Of course, the freer the better.

Even if the 'freedom' collapses in the end, as the top of the pyramid, it basically belongs to the citizens of the world, and it is just a different 'boat'.

This time, the stance is different, and the direction of thinking is of course different.

Born as a businessman, Zhu Yuan will not oppose business, and he also has a certain sympathy for businessmen in this era, but, after all, it is an opposing position to a certain extent, and from the perspective of national interests, some things should be avoided as much as possible.

In short, all kinds of rules, dead or alive, will have some fundamental reference in them.

A gentleman is a gentleman, and he is born from the beginning.

In the yard on the hillside.

This time, we will focus on the chemistry laboratory, which has been renovated recently.

Zhu Yuan wanted to build a chemical laboratory in his own home, but if he thought about it, on the one hand, the houses in this era used too much wood, which was easy to burn, and on the other hand, there were too many poisonous chemicals, in case he polluted his own house and even the surrounding Houhu, it would not be good.

So it's still on this side.

The demarcated chemistry laboratory is rectangular in a north-south direction, nearly an acre in size, with five main rooms on the west side facing east, three rooms on each side, and two rows of east rooms used for storage rooms or changing rooms.

The main house of five rooms is two rooms deep, and the total area is about 200 square meters in a familiar unit of measurement.

The craftsman had just done the fireproof treatment specified by Zhu Yuan on the inside of the house, mainly the top, the beams and columns that were originally exposed, and now made a fireproof ceiling.

Various laboratory utensils have also been moved in.

Many of them were used by Zhu Yuan himself before, such as a set of glassware used to distill alcohol, and so on.

After seeing it so roughly, I pointed out some details that needed to be improved on the spot, and the time came to the evening.

Out of the courtyard gate, there was a sedan chair parked outside that was the only one in the campus, stepped into it, and summoned a sack to come in by the way, and then ordered the outsiders to set off and return to the mansion on the back lake.

The sedan chair was lifted, and Zhu Yuan pulled up the sack girl who habitually knelt at his feet, held it in his arms, and asked with a smile: "Always follow me like this, is it boring?" ”

Lin Xiaoyu hugged the head of his little official, pressed it on his chest, and shook his head gently.

How can it be boring?

Home...... There are so many sisters, I don't know how much I envy her for being able to follow him often.

She's just apprehensive.

is worried that a girl who always follows him like this will let his petty officials be gossiped about.

I wanted to say a few more words, but I was sealed by the girl, and Zhu Yuan stopped talking.

Coming to the north of Houhu Lake, there are boats waiting here, and it is Lin Xiaoyu's father and brother who support the boat, a certain Nizi is not a mute, but he is used to being a little mute by his side, Zhu Yuan got on the boat, and turned to Lin Xiaoyu's father and said a few more words.

Lin Xiaoyu saved his life after all, when he was in Dinghai, anyway...... Zhu Yuan didn't mind supporting the Lin family.

Father Lin became more and more trembling in front of Zhu Yuan, and he was also very satisfied with his current life, that is, he hoped that his grandchildren could go to school and have a future in the future.

He also said that he was too high to climb around, so he could go to the primary school attached to the medical school.

This is a trivial matter, Zhu Yuan directly agreed to come down.

When I got home, the day's affairs were not over, He Xuan greeted me and said that the craftsman Zhu Yuan had ordered to find had arrived, and he was waiting in the front yard.

So he took the shoulder to a meeting room in the front yard.

Or about the steam engine.

These days, Zhu Yuan is already asking craftsmen to make all kinds of parts of the steam engine, which will be made of copper for the time being in order to facilitate shaping.

Gradually, the problem was discovered.

Zhu Yuan planned to build a larger-sized steam engine, about a three-foot diameter boiler with a cylinder diameter of one foot, and planned to achieve the simplest steam engine hammer effect.

It is used to strike iron.

Things are not going well, the key is the cylinder, the preliminary casting, very easy, but, because there is no lathe milling machine and other equipment in this era, all kinds of components, need high precision, can only be polished manually.

Zhu Yuan asked the craftsmen to make many sets at one time.

As long as it can be one.

Now the situation is that they are all polishing little by little.

Speaking of which, there are lathes used to make bearings on the banks of the Yangtze River, but for a set of samples, it is not cost-effective to transform the hydraulic lathes that continue to operate there.

Since there is no shortage of people, let's grind.

It's just that grinding and grinding, the craftsmen don't feel anything, and Zhu Yuan is a little anxious.

I regretted it.

If you had known, the design size should have been smaller.

Steam engines can be miniaturized.

You can be as small as you want.

Like once upon a time, it was as if there was a Gatling model...... Well, Gatling seems to be a machine gun, anyway, it should be something to add, although, it doesn't seem to be a steam engine model, but, in short, it can be made small.

I used to have the impression that steam engines tend to be large-scale, or even huge, mainly because steam engines need to be prepared with a large amount of water and fuel at all times. Just like a steam train, if the boiler is too small, it will be too much of a toss to add water every dozens of miles.

Moreover, the efficiency of the steam engine is also too low relative to the internal combustion engine.

When the small internal combustion engine appeared almost every little time, the miniaturized steam engine was gradually eliminated, and the large steam boiler was actually used all the time.

Now that he has thought of it, the large steam engine is slowly being made, and Zhu Yuan plans to make a set of ultra-small steam models at the same time.

It takes a craftsman.

Yesterday I was instructed to go down, and the general requirement was that it was a craftsman who could make some delicate metal devices, and today the people arrived.

Coming to the front room, there are six people waiting.

Zhu Yuan sat down on the main seat, and after the salute, he asked briefly, these people, some of them had made bird guns before, some made bronze mirrors, and some came from the bearing workshop, and they asked and asked, and one of them attracted Zhu Yuan's attention.

This is a craftsman who has just been escorted from the capital, in his early thirties, named Jin Sango.

Zhu Yuan's first thought was that this person should have two elder brothers, called Dahu and Ergo.

Well.

Well, I didn't talk about this, the key is that this person was carved for the Yuan court royal family before.

Leakage?

Of course Zhu Yuan knows, there is an hourglass at home?

However, probably in a hurry to perform, Jin Sanhu explained in detail that what he made was not the usual hourglass, but a very accurate kind of leakage that could tell the time.

Can you tell the time?

That's a bit too advanced, right?

Let the other party explain again, Zhu Yuan was a little unconvinced, but, it seems, it seems...... What Jin Sango said is not a leak, but a ...... Clock!

Clock?!

This era......

Zhu Yuan never doubted the wisdom of the ancients, but ...... Present, clocks, is not ...... Earlier?

Seeing that Zhu Yuan didn't believe it, Jin Sanhu immediately said that a crystal carving that he personally participated in the production of before was leaked, and then it was given to Emperor Zhizheng first, and he was ...... It should be in Jinling.

The treasures of the Yuan Court Palace were all packed and brought back by Lao Zhu.

If it was really a clock, this was a big deal, even if it was already evening, Zhu Yuan immediately wrote a letter and instructed Zhao Xu to rush to the imperial city in person to inquire about it.

Still in a hurry.

Waiting for Zhao Xu to leave, Zhu Yuan simply asked Jin Sanhu to roughly describe what he said.

is worthy of being a skilled craftsman, even if Jin Sango has not practiced painting, a pencil to draw it, still gives Zhu Yuan a quite vivid 'carved leak' appearance.

This is something similar to a small house model, made of crystal throughout, so it is called a crystal carving, which ...... Not only do there are hands on the dial, but according to Kanesango's description, there are also various gear parts.

Obviously, it's clocks.

Because there was no concept of clocks in this era, since they were used for timekeeping, they were called 'engraved leaks' according to the traditional name.

Not only that, according to Jin Sango's description, according to the rotation of the internal machine yellow, at a certain time, there will be a small wooden figure that will regularly beat a small drum.

Ask deeper.

It turned out that the prototype of this leakage had already appeared in the Northern Song Dynasty.

It was about 300 years ago, the Song Dynasty Prime Minister Su Song presided over the construction of a timekeeping device, called 'Water Transport Elephant Terrace', the Yuan Dynasty followed the Song Dynasty, and also got the Song Dynasty left behind the artwork, and used it as a blueprint to go further.

Water transport elephant platform?

At first glance, I don't understand what it is.

The ancients named it too mysterious.

However, after such an inquiry, Zhu Yuan became more and more sure.

It's not a leak.

It's a clock.

There's a watch, Mingzhou...... No, not only Mingzhou, but many other things, can go further.

There are so many chains, and they can be strung together.

In the blink of an eye, it was dark.

Zhu Yuan was very interested, and He Xuan and Freehand took turns to persuade him to eat something.

When the lanterns in the courtyard were lit one by one, and Zhu Yuan was about to send someone to ask what the situation was, Zhao Xu finally returned with a 'carved leak', and explained that there were too many things in the royal inner curry, and he had been looking for a long time.

At first glance, it was finally confirmed.

Although inlaid with gold and inlaid treasures, it is brilliant and gorgeous, like a mini crystal palace. But, looking at the dial, this is the clock.

Even, for a moment, Zhu Yuan thought, it's good that Lao Zhu hasn't seen it yet, otherwise, with someone's temperament, his first reaction is probably extravagant, too extravagant!

Smash it for me!

Kim Migo was here, adjusting it himself, winding it up, and pushing the hour hand to a position close to the hour.

Many gears inside began to turn, and a clattering sound was heard.

Table!

Does the leak have this sound?

Moreover, Zhu Yuan also quickly determined another thing, which ...... It can be wound, which means that it is yellow steel.

I remember that there was a sword in the terracotta army, which was bent for a thousand years, and when it was taken out again, it was immediately restored to its original state. It can be seen that thousands of years ago, there was already bullet yellow steel.

However, this time, it can be regarded as seeing it with my own eyes.

The process of playing yellow steel must also be obtained.

Recently, the general has been registering and sorting out a large number of craftsmen that Lao Zhu brought back from Dadu before according to Zhu Yuan's requirements, among them, there must be no shortage of corresponding talents.

As long as you have yellow steel, you can do too many things.

Another flurry.

For example, because of the steam engine that came up with recently, the barometer, Zhu Yuan has thought about it, or according to the most basic principles of physics, a bullet yellow, it is almost the same.

It doesn't need to be too precise at the moment.

Another example is the shock absorption of vehicles.

And so on.

His thoughts were spinning quickly, and on the gorgeous 'crystal carving', the hands came to the hour, and with a click, a lifelike little wooden figure in the transparent crystal palace began to beat the drum.

Winter, winter, winter!

This one...... It feels familiar.

Some of the old clocks I've seen have chimerated the time like this, but it's usually a bird.

At the moment, listening to the small drum sound of 'Dong Dong Dong', Zhu Yuan felt as if a new era was coming.

Well.

Next, not only those classics and craftsmen in the Yuan room, but also the various treasures brought back by Lao Zhu, you should also check it out for yourself, and maybe there will be other good things.
