Chapter 823

Xiao Ming closed the fold that Niu Zhen had sent, and his face was full of smiles.

Then Qian Dafu laughed, "the emperor is so happy that he must have conquered the remaining three cities.

"You guessed right. Now all of Guandong is under the control of Dayu state. Now Dayu state has three more prefectures. It's really gratifying." Xiao Ming said.

The three northeast provinces are well-known grain production bases in modern times. The fertile black land makes the grain yield here very high.

It's a pity that the Central Plains Dynasty rarely paid attention to this place, so that it was occupied by different nationalities in various dynasties.

Now that he has recaptured the whole of Guandong, the next step is to build an industrial zone with Anshan as the core and build it into a grain production base. There will also be a large shipyard in the contemporary Liaoning area where Beisha city is located.

"Such a great achievement, the emperor must be famous in history, praise, old slave with the emperor can also touch the light." Qian Dafu laughed more and more happily.

Xiao Ming shook his head helplessly: "I don't care how historians evaluate it. I just hope that Dayu will no longer be bullied by foreigners and stand on the top of the world."

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

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

When the barbarians moved to the west, they had lost their families and could not harass the state of Dayu any more. Now he could finally free his hand to unify the state of Dayu completely.

After all, the king of Yong, the king of Huainan, the king of Chu and the king of Ruyang are still there. Strictly speaking, the state of Dayu is still in a state of division.

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

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

Once the army was still in the Dynasty and had a rest for a while, he would have time to clean up the remaining vassals.

Xiao Ming was not idle, but went on to Qingzhou University under the protection of the bodyguard. Now the daily teaching in Tianzi school is almost the same as a big event of the imperial assembly.

In order to be able to enter the emperor's school and have the honor of being a student of the emperor, the learning atmosphere of Qingzhou university is very strong now, and there are almost no students wandering here.

Every student I saw was walking in a hurry with books, because it was not only Tianzi school, but the selection system pursued by Qingzhou University also put great pressure on students.

If you don't study hard and fail in the exam, you will be dissuaded after two make-up exams, thus losing the qualification of Qingzhou university students.

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

In accordance with the past practice, Xiao Ming went to Qingzhou university to solve some difficult problems at Tianzi school.

Then he went to the laboratory where the key experiments are being carried out.

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

"Emperor, this is the latest improved triple expansion steam engine. Generally speaking, it has completely surpassed the previous single cylinder reciprocating engine."

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

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

The three cylinders are high, medium and low cylinders respectively. The steam engine expands three stages in the three cylinders, so as to improve the thermal efficiency of the steam engine.

Therefore, the real advantage of the triple expansion steam engine lies in the three times utilization of the steam engine. That is to say, after the steam enters the first cylinder to do work, it will enter the second cylinder to do work, and then the third one. In this way, the same amount of steam engine can make the steam engine do more work.

In this way, with the same amount of coal and water, the steam engine enables the steamer to travel further at sea.

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

In his time, it was very difficult to replenish at sea. It would be a huge saving to reduce the number of fuel supply points.

To be able to produce a single cylinder reciprocating steam engine, the accessories of the three cylinder steam engine are naturally not a problem. After all, the materials used are the same.

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

So the reason why it took such a long time to develop successfully is to test the material strength required by the steam engine and the use of the safety valve in the steam engine.

However, the state of Chongqing already has a barometer. After properly discharging the steam pressure with the safety valve, the high temperature and high pressure steam engine is much more stable now.

Because of this, Lin Wentao announced the successful development of the triple expansion steam engine."I haven't been busy in vain for such a long time, but now you can't be idle. You need to produce this kind of steam engine and deliver it to the shipyard immediately. Zhang Liangke is waiting for your steam engine to transform the warship." Xiao Ming looks at the steam engine in the laboratory and is very satisfied.

This is similar to the triple expansion steam engine in the science and Technology Library. With the basic industrial capacity, many machinery manufacturing becomes easier. Only qualified accessories are needed, some machinery can be successfully manufactured. The only thing that needs to be strengthened is the strength and precision of accessories.

Lin Wentao breathes a sigh of relief when he hears that the three expansion steam engine is finally qualified. Since Xiao Ming is staring at the laboratory, everyone is nervous now, in order to finish the goal one day earlier.

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

Now every time I meet with officials, they no longer look down on it. On the contrary, they are envious.

"Yes, Emperor. When I went back, I arranged for the craftsman to make the three expansion steam engine. But what's the task of the research room below?" Lin Wentao is looking forward to the fact that they are busy studying science and technology.

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

In the field of steam engine, Lin Wentao still has a lot to go, and the multi expansion steam engine is a steam turbine, but Xiao Ming doesn't expect to achieve this in five or six years.

This is because it is the technology of the first World War, but although it can not be realized, it is necessary to reserve technology in advance.

So he said, "continue the development and improvement of the multi expansion steam engine. If you have energy, you can consider the steam turbine, which is a revolutionary power machinery for both ships and electric power."

Lin Wentao has also come into contact with the concept of steam turbine in his books, but this kind of thing is obviously more complex than steam engine. At present, the industrial capacity of Qingzhou is unable to produce it.

However, thinking of Su Liangcai's good progress in electric power research, he had a faint expectation in his heart.
