[Please go to the starting point to give Heng Yi a collection, thank you]

Here Yun is carrying out all kinds of publicity for the large-scale auction held on the second day of the first month of June, hoping to attract more people to come, over there Yunyi left Yunhua County with his disciple Li Xiu, went to (Qingshan) iron mine, inspected iron ore and steel plant, the steel plant is about to open a furnace to make steel, there is no professional and technical personnel, Yunyi can only sit in person, although Yunyi is not a technical talent, fortunately, Yunyi has a knowledge reserve that others can never match, and it is better to talk on paper than nothing.

And take Li Xiu, after Li Xiu has mastered some knowledge of machinery and steam engines, he will take over the steam engine manufacturing plant, and he will also have to deal with steel, and it is also necessary to bring Li Xiu here to gain knowledge.

Li Xiu's figure is fat, it is difficult to drive a fast horse for a long journey, and it took more than a day for the group to arrive at the Qingshan Iron Mine, which is still the case that the road to the Qingshan Iron Mine has been rested, if you don't take Li Xiu, I'm afraid that the group will set off in the morning and arrive in the afternoon.

However, with Li Xiu, the group stopped and stopped, jolting on horseback, Li Xiu's eyebrows gradually wrinkled, obviously unbearable, but fortunately, they arrived at their destination soon, and Li Xiu persevered.

Yun Yi looked at Li Xiu, whose face was not very good, shook his head and sighed: Maybe I should think of a way to let this disciple reduce his body shape.

There is a Qingshan town outside the Qingshan Iron Mine, which is inhabited by workers and their families in iron mines, iron and steel mills, masonry yards, and cement factories, with a total population of more than 3,000, which is a relatively large town.

The town was built according to a certain plan, most of the houses are about the same size, located in a good way, not cluttered at all, although most of the people in the town live in the workers and their families, but the common people's lives of various ancillary industries have also begun to rise, and there are vendors selling all kinds of things on both sides of the street.

In the future, as the scale of the steel mill continues to expand, the population here will soon exceed 10,000, and then the town of Qingshan will become Qingshan County, and the four walls will protect it.

Yun Yi asked his subordinates to take Li Xiu to Qingshan Town to rest, and then continued to drive towards the steel mill.

In Qingshan Town, Yunyi could see the billowing smoke coming from the chimney of the steel mill not far away, and the surrounding environment was rapidly deteriorating, and there was even a pungent smell in the air.

For this situation, Yunyi has no good solution, the development of industry will inevitably bring pollution, but with Yunyi, the speed of industrial progress will be very fast, and advanced technology can reduce pollution.

Now Yunyi can only take out a pair of white masks from his cuffs and try to breathe less of these industrial exhaust gases.

Yunyi's subordinates are also curious about Yunyi wearing a mask, they don't know what this mask is and what it does, and the gap in identity makes his subordinates dare not ask at will.

Soon, the group arrived at the steel plant, after all, the workers' homes could not be too far away from the steel plant and the mine, otherwise a lot of time would be wasted on the road throughout the day.

At the gate of the steel plant, Yun Yi could see ox carts and horse-drawn carts coming in and out, transporting iron ore and coal into the steel plant, and then driving out empty.

The person in charge of the Qingshan Iron Mine is named Yang Yuan, Zi Jichang, Chinese New Year's Eve, medium stature, ordinary appearance, was previously the manager of the Yun Clan's Commercial Bank, and then was transferred to Yun Yi by Yun Yuankai, responsible for managing the affairs of the Qingshan Iron Mine, Yang Yuan In addition to not being responsible for the affairs of Qingshan Town, the affairs of iron mines, steel plants, masonry yards, and cement factories are all managed by Yang Yuan.

Yang Yuan has no technical knowledge, and the main thing he is responsible for is to arrange all kinds of personnel, arrange the right people in the right place, and do not do the thing of laymen directing insiders, so that there is no big mess here, if there is really a big mess, Yunyi would have come to inspect it a long time ago, instead of waiting until the steel mill is about to start steelmaking.

Yang Yuan knew in advance that Yunyi was coming to Qingshan Iron Mine, but Qingshan Iron Mine was not too close to Yunhua County, and Yang Yuan didn't know when Yunyi would come, so he didn't come out to greet Yunyi in advance, but Yang Yuan informed the guards everywhere that once he saw Yunyi's arrival, he would quickly inform him, at this moment, I am afraid that Yang Yuan already knew about Yunyi's arrival and was rushing to Yunyi's side.

Yun Yi did not walk into the steel plant, there are guards in the steel plant, and the guards are still the people of the Yun family, and the guards behind Yun Yi are wearing the standard clothes of the Yun family, knowing that they are their own people, they will not stop Yun Yi and his party, and the guards have only come out who is it, and someone has already run into the steel plant to report Yang Yuan.

Yun Yi, who was standing at the gate of the steel factory, looked at the ox carts and horse-drawn carts coming and going, and fell into deep thought, Yunyi found a problem: the transportation efficiency of ox carts and horse-drawn carts was very low.

How big is an ox cart and horse-drawn cart, how many things can be transported, the speed of the ox cart and horse-drawn cart carrying goods is greatly reduced, and how much higher the transportation efficiency can be, and now the scale of the steel plant is still small, so the transportation efficiency can still be maintained, if the scale of the steel plant is expanded, then the efficiency will be far from enough.

In Yunyi's view, it is very simple to improve the efficiency of transportation, although it takes a long time for steam locomotives to be manufactured, but if the track is laid, so that the ox cart and horse-drawn cart can run on the track, the transportation efficiency can also be greatly increased.

Yun Yi saw in the Yun family's collection that a disciple of the Mo family had invented a kind of railroad, that is, a track laid with hard wood, the principle is similar to that of a modern railway, except that one is pulled by a steam locomotive, and the other is pulled by horsepower.

In the heyday of the Shengwu Dynasty, a large number of such wooden rails were built, and the Shengwu Dynasty could use this wooden rails to quickly transport large armies or grain and grass, and it is said that horse-drawn carriages could travel more than 1,200 miles on it.

If you lay rails on the road from the mine to the steel plant and from the coal mine to the steel plant, you can greatly increase the transportation efficiency, but the wooden track is still a little troublesome, and it is easy to be damaged, it is better to wait for the steel production to increase after the forging of the rail to lay the railway, but also to prepare for the steam locomotive.

Yun Yi wrote down this matter in his mind, and planned to implement it later, and then Yun Yi's eyes turned to the steel plant, and Yun Yi had already seen Yang Yuan walking briskly towards this side.

"Humble welcome to the Lord." Yang Yuan faced Yunyi and saluted respectfully.

"Hurry up, Ji Chang is happy." Yun Yi stepped forward in a few steps and helped Yang Yuan up.

Yun Yi and Yang Yuan chatted briefly and learned about the general situation of the steel plant, which is currently operating normally, has smelted a large amount of pig iron, and is about to start steelmaking, and there have been no accidents during this period.

Note 1: The rail road appeared during the Qin Dynasty, and you can Baidu for specific information.
