Xiao Ming closed the fold sent by Niu Ben, and a heavy smile appeared on his face. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Qian Dafu on the side laughed, "The emperor is so happy, it must be that the remaining three cities have been conquered."

"You guessed right, now that the Kanto region is all under the control of the Great Chongqing Kingdom, the Great Chongqing Kingdom is now equal to three more prefectures, which is really gratifying." Xiao Ming said.

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

It's just a pity that the Central Plains Dynasty rarely set its sights on here, so that it has been occupied by foreign races in various dynasties.

Now that he has recaptured the entire Kanto, the next step is to establish an industrial zone with Anshan as the core, and at the same time make it a grain production base, and there will be a large shipyard in the modern Liaoning region, where Beisha City is located.

"With such great achievements, the emperor will definitely leave a name in history and be praised by all generations, and the old slave will be able to follow the emperor with his glory." Qian Dafu smiled more and more happily.

Xiao Ming shook his head helplessly: "I don't care what the historian says, I just hope that the Great Yu Kingdom will no longer be bullied by foreign races and stand on top of the world." ”

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

Now that the Kanto region was settled and there was no need for so many troops to be stationed outside, he had to recall most of the musketeers.

The barbarian people moved west, and now they are already lost dogs, and they have no power to attack the Great Chongqing Kingdom again, and now he can finally free up his hands to completely unify the Great Chongqing Kingdom.

After all, the kings of Yong, Huainan, Chu, and Ruyang are still there, and strictly speaking, the Great Chongqing Kingdom is still in a state of division.

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

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

Once the army returned to the dynasty and rested for a while, he would have time to clean up the remaining vassal kings.

After explaining the matter, Xiao Ming was not idle, but went to Qingzhou University under the protection of the guards, and now the daily teaching of the Son of Heaven Academy has almost become a major event equivalent to the court meeting.

In order to be able to enter the Son of Heaven Academy and have the honor of being a protégé of the Son of Heaven, Qingzhou University now has a strong learning atmosphere, and there are almost no students hanging out here.

Every student I saw was in a hurry with a book, because not only the Tianzi Academy, but also the selection system pursued by Qingzhou University also put a lot of pressure on the students.

If you don't study hard and fail the exam, you will be persuaded to quit after failing the two make-up exams, and you will lose your qualification as a student of Qingzhou University.

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

According to the past practice, Xiao Ming went to Qingzhou University and first answered some difficult questions in the Tianzi School.

He then went to the laboratory, where the key experiments were currently being conducted.

Unlike in the past, he is now directly involved in various experiments as a technical consultant, and he has developed a set of science and technology to be developed successively, and the technology in the science and technology crystal is realized step by step.

"Your Majesty, this is the latest improved three-expansion steam engine, which has completely surpassed the previous single-cylinder reciprocating engine in general."

Xiao Ming is now in Lin Wentao's laboratory, and after repeated improvement experiments, now Lin Wentao has finally built 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, and the steam engine undergoes three-stage expansion in the three cylinders, thus improving the thermal energy efficiency of the steam engine.

Therefore, the real advanced place of the three-expansion steam engine lies in the three utilization of the steam engine, that is, the steam will enter the second cylinder to do work after entering the first cylinder to do work, and then the third, so that the same amount of steam engine can make the steam engine do more work.

In this way, with equal amounts of coal and water, the steam engine was able to allow the steamer to travel farther at sea.

To put it simply, this is the equivalent of the fuel consumption of a modern car, and the utilization rate of fuel will determine how far the car can go under the same conditions.

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

To be able to manufacture a single-cylinder reciprocating steam engine, 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 of high-temperature and high-pressure steam engines, which is not uncommon in history.

Therefore, the reason why it took so long to develop was to experiment with the strength of the material required for this steam engine and the use of safety valves on steam engines.

However, Dayu already has a barometer, and after properly discharging the steam pressure with the safety valve, the high-temperature and high-pressure steam engine is now much more stable.

Because of this, Lin Wentao announced the successful development of the three-expansion steam engine.

"It's been in vain for so long, but now you can't be idle, 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 battleship." Xiao Ming looked at the steam engine in the laboratory and was very satisfied.

This is not much different from the three-expansion steam engine in the science and technology library, after having the basic industrial capacity, a lot of machinery manufacturing has become easy, only qualified accessories, some machinery can be manufactured smoothly, the only thing that needs to be strengthened is the strength and precision of the accessories.

Lin Wentao breathed a sigh of relief when he heard this, the three-expansion steam engine was finally qualified, since Xiao Ming stared at the laboratory, now everyone has tensed their nerves, in order to complete the goal one day earlier.

Although the pressure was greater than before, Lin Wentao was still very happy in his heart, and the honor of studying the steam engine with the emperor was not something anyone could get.

Now, every time they meet with the officials, they no longer have the slightest contempt, on the contrary, they are extremely envious.

"Yes, Your Majesty, the lower officials will arrange for craftsmen to make three-expansion steam engines when they go back, but what is the task of the research room below?" Lin Wentao was a little expectant, they couldn't stay idle studying science and technology.

Xiao Ming hesitated for a moment, in fact, for him, the three-expansion steam engine was just the beginning, and this kind of steam engine was just the simplest multi-expansion steam engine.

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

Because this is completely the technology of the contemporary World War I, but although it cannot be realized, it is necessary to reserve the technology in advance.

So he said; "Continue to develop and improve the multi-expansion steam engine, if you still have the energy, you can consider the steam turbine, whether it is for ships or electricity, this is a revolutionary power machine."

Lin Wentao has also come into contact with the concept of steam turbines in books, but this kind of thing is obviously much more complex than steam engines, and Qingzhou's current industrial capacity cannot be manufactured.

However, thinking that Su Liangcai's electric power research is progressing well, he has a faint expectation in his heart.
