After the third major purge, Su Yonglin still has a lot to be busy with.

In addition to government affairs, he also needs to take some time to invest in the technical department to pay attention to how technicians have made progress in tackling the technology he is looking forward to.

As of now, in addition to successfully achieving technical difficulties such as coking, steelmaking and firearm manufacturing, Ming Guo’s technical department has many other technical problems.

For example, the practical steam engine that Su Yonglin hopes they will study.

In the Ming Dynasty in the ninth year of Hongwu, steam engines were definitely not without markets. If they were really developed successfully, steam engines that could be put into the market, this advanced machine would definitely be widely used in the mining farms of Ming Dynasty in a short period of time.

The steam engine first acted in the mines, helping miners work and used to remove groundwater from mines.

In the current Ming Dynasty, because the imperial court promoted the movement of coal as a daily raw material, the demand for coal in the Ming Dynasty market has soared, and the surge in coal demand has been reflected in the emergence of more and more coal mines.

The emergence of coal mining farms provided a large number of jobs for the Ming Dynasty. A considerable number of rural surplus laborers in the main coal mines left the land, entered the workshop, and chose to become a full-time worker, and the number of working class was expanded.

The more people of the working class, the more urgent the demand for industrial production technology. Once industrial technology has made breakthroughs, it will be put into production and use as quickly as possible.

In the coal mine work area, with the development and excavation of mineral deposits, they will naturally go deeper and deeper into the ground. Once they go deeper into the ground, they will face the problem of mine groundwater.

In certain extremely dangerous situations, groundwater can even threaten the lives of workers.

Faced with these problems, without the help of more advanced production tools, the staff and managers of coal mining farms used their brains to find ways to use manpower and livestock to drain water.

Because of the difficulty of drainage, the Ministry of Works also taught them how to use pulley groups at their request to help them save effort.

Pullax set drainage is now the mainstream drainage method in many mining areas, which has improved production efficiency in a certain sense.

However, compared with the huge groundwater system, whether it is human or animal power, even if the pulley set is added, the displacement still seems to be a drop in the bucket, which is far from enough.

Therefore, when coal mining sites face groundwater interference, mining factories often need to spend a lot of manpower and material resources to drain water, which will lead to a reduction in production efficiency and a significant increase in production costs. The output of coal on the market cannot increase, and the price will be difficult to continue to be paid.

Sometimes, due to practical reasons, many coal mining sites have to give up some mining areas with too much groundwater and choose to develop other mining areas.

This will also cause a certain degree of waste of resources.

In this case, Su Yonglin felt that it would be a very meaningful thing to be able to launch a steam pump in time and would be welcomed by miners. If the steam pump is realized, the threshold for the industrial era will be near to Mingguo.

The working principle of the steam engine is actually very simple and not difficult to solve. Even the technicians of the Ministry of Industry have built a research steam engine of one person the size of a person, which has basically realized the operating principle of the steam engine and can realize the pumping work.

Through steam, filling and condensation, Su Yonglin watched the steam engine drain a cylinder of water with his own eyes. The scene gave Su Yonglin a sense of surprise and excitement that transcends the times and goes against the will of heaven.

To be honest, compared to the amount of groundwater in the mining area, this steam engine is like a child scooping water in the river with half of the gourd.

The small amount of water pumping and the limitations of implementation conditions make this steam engine have no market value. It must be improved and improved until it has market value. It will be considered truly successful.

However, the implementation of the principle made Su Yonglin particularly excited because they found the right direction, so as long as they invest a lot of energy to improve continuously, the days of success will definitely come.

With the first success, more successes that followed will follow, and the production state of the entire Ming Dynasty will undergo tremendous changes.

In order to realize the steam pump, Su Yonglin invested millions of money to hand over to the technicians of the Ministry of Industry, giving their raw material demand a green light, but the progress so far is still limited.

At the end of October, Su Yonglin inspected the Ministry of Industry and went to see the working progress of the steam unit. Then he found that they made a series of improvements to the steam pump, which achieved more than twice the working efficiency compared to the original version of the steam pump.

However, it still has no market value and is easy to damage. It is also quite difficult to operate. It is still a bit difficult for the generally deep mines and needs to be improved.

The members of the working group were very frustrated and felt that they were sorry for Su Yonglin's efforts and such strong financial support.

Many departments need money to be approved by the Ministry of Finance, and they are closely watched. However, when the Ministry of Industry Research Department needs money, they almost made a request in the morning, and in the afternoon someone came to send the money to them and gave them a green light.

Faced with such preferential treatment and attention, these technicians who master the current highest-end technology cannot give corresponding results, and they feel very sad.

Su Yonglin could only continue to encourage them and tell them that the development of technology was not achieved overnight. Don’t worry, let them develop steam engines in a larger, faster and stronger direction, so that this brand new power equipment will bring a better tomorrow to the Ming Dynasty.

Looking at the steam pump that can complete the pumping action, Su Yonglin saw full of hope for the future.

In October of the ninth year of Hongwu, this was the beginning of everything.

Su Yonglin has no doubt that these excellent technicians can ultimately break through various restrictions and successfully create market-worthy steam engines, and will continue to add a large amount of investment.

He hopes that at this time next year, he will see a [Friends of Miners] who are more friendly to miners and can invest in mining factories, which will truly bring light to the transformation and leap in productivity.

When the cold wind in Zhongdu began to blow unscrupulously, Su Yonglin received two messages.

First, Dali Kingdom sent people to pay tribute.

Second, the Khwarezm sent people to pay tribute.

It was within Su Yonglin's expectation that the Dali Kingdom sent people to pay tribute.

Because the army led by Su Haisheng and the Eighth Corps under construction and training put huge pressure on the Dali Kingdom, it was natural for Dali Kingdom to come to pay tribute and find out the trump card of the Ming Dynasty.

But what does Khwarezmian come to pay tribute?

According to the report of the Tianwang Army spy who returned from "doing business" in Western Liao, Su Yonglin learned that the Khwarezmian Kingdom was in the west of Western Liao.

The western territory of Western Liao has expanded to Central Asia, which puts huge pressure on the Abbasid and Gur dynasties and has great influence in Central Asia.

The Khwarezmian Kingdom also lived there, separated from the Ming Dynasty by thousands of mountains and rivers.

There cannot be said that there is no intersection between this country and the Ming Dynasty, or that there is no exchange. There has been no intersection in history since the Tang Dynasty. It has been three or five hundred years. What did they do when they came to pay tribute?

Just giving gifts, or...

I hope the Ming Dynasty launches a military attack on Western Liao?

Are there many conflicts between the Khwarezmian Kingdom and the Western Liao Dynasty?

Su Yonglin had some of his own ideas about this.

Then he announced that he would first meet with the envoy of Dali, have a conversation with the envoy of Dali, and then go to meet with the envoy of Khwarezm.
