Xiao Ming closed the note sent by Niu Ben, and a strong smile appeared on his face.

Qian Dafu, who was standing beside him, then smiled, "The emperor is so happy, probably because the remaining three cities have been conquered.

"You guessed it right. Now all Kanto is under the control of the Great Yu Kingdom. Now the Great Yu Kingdom has three more land, which is really gratifying." Xiao Ming said.

The three northeastern provinces are famous grain production bases in contemporary times, and the fertile black soil makes the grain production here very high.

It’s just a pity that the Central Plains dynasty rarely turned their attention here, so that it has been occupied by foreign races in various dynasties.

Now that he has regained the entire Guandong, he will build an industrial zone with Anshan as the core and build it into a grain production base. There will be a large shipyard in the contemporary Liaoning area where Beisha City is located.

"The emperor will definitely leave such great achievements in history and praise it for generations. I can also benefit from it with the emperor." Qian Dafu smiled even more and more happily.

Xiao Ming shook his head helplessly: "I don't care how the historians comment. I just hope that the Great Yu Kingdom will no longer be bullied by alien races and stand on the top of the world."

After saying that, Xiao Ming remembered something and picked up his pen.

Now that Kanto has settled, there is no need for so many troops to be stationed outside, he wants to recall most of the musketeers.

The barbarians moved westward and were now a stray dog ​​and were unable to harass the Great Yu Kingdom any longer. Now he can finally free up his hands to completely unify the Great Yu Kingdom.

After all, King Yong, King Huainan, King Chu, and King Ruyang are still there. Strictly speaking, the Great Yu Kingdom is still in a state of division.

Only by stabilizing the country can he concentrate on using firearms that are more advanced than Europeans to end the Western colonial era.

After writing an edict to recall the army, Xiao Ming asked Qian Dafu to send eunuchs to Jinzhou.

Once the army was on the verge of the army and rested for a while, he would have time to clean up the remaining vassal kings.

After explaining this, Xiao Ming did not stay idle, but went to Qingzhou University under the protection of the guards. Now that daily lectures at the Emperor's School have almost become a major event equivalent to a court meeting.

In order to be able to enter the Emperor's School and have the honor of being a disciple of the Emperor, Qingzhou University is now in a strong learning atmosphere, and there are almost no students wandering around here.

Every student I saw was walking in a hurry with books, because not only the Emperor’s School, but also the selection system pursued by Qingzhou University also put a lot of pressure on the students.

If you do not study hard and fail the exam, you will be persuaded to withdraw after failing the two remedies, thus losing the qualification of a student at Qingzhou University.

For many poor students, this kind of thing is intolerable, because everything is free at Qingzhou University, and they cannot find a better place.

According to previous practice, when Xiao Ming went to Qingzhou University, he first answered difficult questions at the Emperor's School.

Next he went to the laboratory where the key experiments are currently underway.

Unlike in the past, he has now directly participated in various experiments as a technical consultant, and he has formulated a set of science and technology to be developed one after another to realize the technology in the scientific and technological crystal step by step.

"Your Majesty, this is the most recent and improved three-inflated steam engine. Overall, it has completely surpassed the previous single-cylinder reciprocating machine."

Xiao Ming is now in Lin Wentao's laboratory. After repeated improvements, Lin Wentao has finally made a three-inflated steam engine.

In fact, the principle of this steam engine is similar to that of a simple reciprocating machine, except that this steam engine has three cylinders.

These three cylinders are high, medium and low cylinders respectively. The steam engine expands in three stages in three cylinders, thereby improving the thermal energy efficiency of the steam engine.

Therefore, the real advanced part of the three-inflated steam engine lies in the three-time utilization of the steam engine. That is to say, after the steam enters the first cylinder for work, it will enter the second cylinder for work, followed by the third one. In this way, the same steam engine can allow the steam engine to do more work.

In this way, with equal coal and water, this steam engine can allow the steamship to sail further on the sea.

To put it simply, this is equivalent to the fuel consumption problem of Hyundai cars. The fuel utilization rate will determine how far the car can run under the same conditions.

In his time, sea supply was a very difficult thing, and it would be a huge savings to reduce fuel supply points.

If a single-cylinder reciprocating steam engine can be made, the accessories of these three-cylinder steam engines are naturally not a problem, after all, the materials used are the same.

The only thing to worry about is the explosion problem caused by excessive pressure in high-temperature and high-pressure steam engines. There are many such examples in history.

So the reason why it took so long to successfully develop is to experiment with the material strength required for this steam engine and the use of safety valves on the steam engine.

However, the Great Yu Kingdom already has a gas pressure gauge. After appropriately discharged steam pressure with the safety valve, the high-temperature and high-pressure steam engine is now much more stable.

It is precisely because of this that Lin Wentao announced the successful development of the three-inflated steam engine.

"It's been a waste of work for such a long time, but you can't be idle now. You have to produce this steam engine and deliver it to the shipyard immediately. Zhang Liang can wait for your steam engine to transform the warship." Xiao Ming was very satisfied with looking at the steam engine in the laboratory.

This is almost the same as the three-expansion steam engine in the technology library. After having basic industrial capabilities, many machinery manufacturing has become easier. Only qualified accessories are required and some machinery can be manufactured smoothly. The only thing that needs to be strengthened is the strength and accuracy of the accessories.

Lin Wentao breathed a sigh of relief when he heard this. The three-inflated steam engine was finally qualified. Since Xiao Ming stared at the laboratory, everyone has been nervous now, just to achieve the goal one day earlier.

Although the pressure is greater than before, Lin Wentao was still very happy. Not everyone can get the honor of studying steam engines with the emperor.

Now every time they meet with officials, they never show any contempt. On the contrary, they are extremely envious.

"Yes, the emperor, the officials will arrange for the craftsman to create a three-inflated steam engine when they go back. However, what is the task of the research room below?" Lin Wentao was somewhat expectant, and they were unable to stop studying technology.

Xiao Ming hesitated for a moment. In fact, for him, the three-inflated steam engine is just the beginning. This steam engine is just the simplest multi-inflated steam engine.

In the field of steam engines, Lin Wentao still needs a lot of roads to go, and the multi-swelling steam engine is a steam turbine, but Xiao Ming does not expect this thing to be realized within five or six years.

Because this is completely a technology from the contemporary World War I period, although it cannot be achieved, advance technical reserves are still necessary.

So he said, "Continue to develop and improve multi-swell steam engines. If you still have the energy, you can consider the steam turbine. Whether for ships or electricity, this is a revolutionary power machinery."

Lin Wentao has also been exposed to the concept of steam turbines in books, but this kind of thing is obviously much more complicated than steam engines, and Qingzhou's current industrial capacity cannot be manufactured.
