The section of railway built by Yan Lide is only more than 40 miles.

So the train didn't run long before it came to an end.

After some complicated manoeuvres, the train began to return.

During this period, Li Shimin and others also basically understood how the train operated.

After everyone returned to Chang'an City, the construction of the railway was quickly decided.

As soon as the people around Chang'an City finished their farming work, they got a lucrative job again.

With the increase of people's income, more and more people come to Chang'an City from the surrounding area to play and shop.

At the same time, the real estate business, which was disliked by all merchants in Chang'an City, also began to heat up.

Today's Pei Mingli is already well versed in the truth of making a fortune in a muffled voice.

In the past two years, he has made a lot of money through the real estate business.

Pei Mingli first bought a large amount of cheap idle land in Chang'an City to build houses.

These houses are then used to exchange with those who live in prosperous areas but do not have the means to repair their homes.

When the houses in these prosperous areas were built again, he would immediately be able to sell them at a high price to foreign merchants who were eager to move into Chang'an City.

Nowadays, as the people's incomes are getting higher and higher, even some people around Chang'an City have begun to yearn to move into Chang'an City.

Therefore, Pei Mingli decisively seized this wave of business opportunities and cooperated with Datang Bank to vigorously promote the loan purchase project.

As the population of Chang'an City continued to grow, Li Zhi decisively asked Pei Mingli to build some more residences in the industrial park in the west of Chang'an City.

There are both markets and factories here, as well as colleges.

Not only that, the road to Chang'an City here is wide and smooth.

With the increasing popularity of horse-drawn carriages and bicycles, the time to travel between the two places has been greatly reduced.

Wouldn't it be a big loss if such a good place was not developed well?

Just when Li Zhi's eyes were about to turn to the direction of making money for himself, Yan Liben and Li Dejian gave him a big surprise.

After a lot of hard work, the two finally built a four-stroke gasoline engine.

This achievement made Li Zhi very happy.

With gasoline engines, motorcycles and cars are not far from application.

As long as we work harder to solve problems such as gearboxes, then the only thing Datang needs to do in the future is to build roads.

Today's post stations should be banned, and those that can be changed into hotels will be turned into hotels.

The saved horses were sent directly to the people in remote areas.

If each village had one or two horses, it would be much easier for everyone to travel when they wanted.

As long as people in these remote areas can easily get in and out, they will see what is going on in developed areas sooner or later.

At that time, many people will start to work in developed areas to make money.

In this way, Datang still has a chance to achieve urbanization with a small population.

If urbanization can be achieved at a time when the population is small, then Datang officials will be able to adapt to urban management very easily.

In the next few years, when the population starts to explode, it will be much easier for them to cope.

Thinking of this, Li Zhi excitedly circled around the running engine in front of him several times.

After the excitement, Li Zhi said to Yan Liben and the two: "Organize more people to study motorcycles and cars as soon as possible."

At the same time, the development of diesel engines should also be stepped up. ”

Many large machines and equipment still use diesel engines to be more efficient.

And the ships of the future will also be mainly diesel powered.

Yan Liben and Li Dejian bowed down and agreed.

This work will be done by the superintendents, who are already doing it.

Although Li Zhi did not provide them with detailed drawings, the specific process requirements had already been given.

After Li Zhi said goodbye to Yan Liben and the two, he was just about to leave and be a prisoner, but he was stopped by Pei Kuanshu, who was hurriedly found.

I only heard him happily open his mouth and say to Li Zhi: "Your Highness, hurry up and follow the lower officials to the Shaofu Prison."

The watch you want has already been made. ”

After listening to Pei Bandshu's words, Li Zhi couldn't help but look up at the sun in the sky.

What day is it?

How can good things come one after another?

The engine had just been developed, and the watch was about to be launched.

Do you know that the grandfather clock that has just started to be sold to the outside world is still in the hot sale period?

Li Zhi was a little dazed and followed Pei Kuanshu to the Shaofu Prison, and was directly taken into the public house by him.

Pei Kuanshu came to his desk and took out the key to open the drawer.

Then he cherished the two brocade boxes in front of Li Zhi.

Li Zhi picked up a brocade box and opened it to find that it was a men's watch.

While Li Zhi picked it up, Pei Kuanshu introduced on the side: "The strap is made of cowhide.

The dial and case are made of stainless steel.

As for the surface, it is tempered glass. ”

Li Zhi nodded as he looked at the watch in his hand.

The color of the dial is pale yellow, and the indexes are black.

The date can be displayed in the position in the count.

Li Zhi turned the watch upside down to look at the back.

Pei Bandshu said on the side at this time: "The movement uses the tourbillon technology proposed by His Royal Highness. ”

After listening to Pei Kuanshu's words, Li Zhi said in surprise: "The process requirements of tourbillon technology are not low.

Didn't you choose an easier movement? ”

Pei Kuanshu opened his mouth and said: "What Xiaguan and the others are challenging is the best craftsmanship that can be achieved at the moment.

As for the other movements, there are others who are producing them. ”

Li Zhi nodded after listening to Pei Bandshu.

Then he said to him: "You can find a few excellent craftsmen to study more."

Watches are a commodity that will be popular for many years.

The more complex the movement used, the more accurate the time display. ”

Pei Mingli nodded after listening to Li Zhi's words.

At this time, Li Zhi opened the brocade box next to him again.

Inside is a women's watch.

The individual components are made of the same material as the men's watch.

The difference is that the women's watch is smaller than the men's watch, and the color of the dial has changed to pink.

Li Zhi put the two watches together and compared them for a long time.

Then he said to Pei Bandunshu with satisfaction: "The young eunuch is worthy of being the peak representative of the Tang Dynasty's handicraft industry.

Such exquisite skills are the top machinery of Datang today, and it cannot be compared.

Aside from the rest, this watchmaking technique alone is enough for craftsmen from the outside world to learn for decades. ”

After listening to Li Zhi's words, Pei Bandshu said: "Your Highness has benefited, and the ministers were able to produce this watch thanks to the drawings given by Your Highness." ”

Li Zhi waved his hand and said: "This king doesn't dare to accept this credit."

The drawings given by this king are only approximate, and even the accuracy requirements are not marked.

It's entirely up to you to be able to make it in such a short period of time. ”

After listening to Li Zhi's words, Pei Bandshu bowed down to the lower officials and thanked His Highness for his praise.
