Iron Dynasty

Xiao Ming closed the booklet brought by Niu Ben with a heavy smile on his face.

Qian Dafu on the side laughed, The emperor is so happy, presumably all the remaining three cities have been conquered.

You guessed it right, now all of the Guandong Kingdom is under the control of the Great Yu Kingdom, and now the Great Yu Kingdom is equal to the land of three more prefectures, which is really gratifying. Xiao Ming said.

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

It's just a pity that the Central Plains Dynasty rarely set its sights on this place, so that it has always been occupied by aliens in various dynasties.

Now that he has recaptured the entire Kanto, the next step is to build an industrial zone with Anshan as the core, and at the same time turn it into a food production base, and there will also be a large shipyard in the contemporary Liaoning area where Beisha City is located.

Such great achievements, the emperor must be remembered in history, praised by all ages, and the old slave can follow the emperor. Qian Dafu laughed even more happily.

Xiao Ming shook his head helplessly: I don't care what the historians say, I just hope that the Great Yu Kingdom will no longer be bullied by aliens and stand on top of the world.

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

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

The barbarians have moved westward, and they are now lost dogs, unable to harass the Great Yu Country any more. Now he can finally free up his hands to completely unify the Great Yu Country.

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 when the country is settled can he concentrate on ending the colonial era of the West with more advanced firearms than Europeans.

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

Once the army returns to court and rests for a while, he will have time to clean up the remaining vassal kings.

After explaining the matter, Xiao Ming did not sit idle, but went to Qingzhou University under the protection of the guards. Now, the daily teaching of the Tianzi Academy has almost become a major event equivalent to the court meeting.

In order to be able to enter the Tianzi Academy and have the honor of being a disciple of the Emperor, Qingzhou University now has a strong learning atmosphere, and there are almost no students hanging around here.

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

If you don't study hard and fail the exam, you will be dismissed after two make-up exams, and you will lose your qualifications as a student at Qingzhou University.

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

According to the usual practice, Xiao Ming went to Qingzhou University to answer some difficult questions at the Son of Heaven Academy.

Next, he went to the laboratory where key experiments are currently being conducted.

Different from the past, now he is directly involved in various experiments as a technical consultant, and he has formulated a set of science and technology to be developed successively, and realizes the technology in the technology spar step by step.

Your Majesty, this is the very latest and improved three-expansion steam engine. Overall, it has completely surpassed the previous single-cylinder reciprocating engine.

Xiao Ming is now in Lin Wentao's laboratory. After repeated experiments of improvement, 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, respectively, and the steam engine performs three-stage expansion in the three cylinders, thereby improving the thermal energy efficiency of the steam engine.

Therefore, the really advanced part of the triple expansion steam engine lies in the three-time 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 steam engine volume can be Let the steam engine do more work.

In this way, this steam engine can make steam ships travel farther at sea using equal coal and water.

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

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

To be able to manufacture a single-cylinder reciprocating steam engine, the accessories of this 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.

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

However, Dayu Country already has a barometer. After the steam pressure is properly discharged 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 triple expansion steam engine.

After all this time, it's not in vain, 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 looked at the steam engine in the laboratory. satisfy.

This is similar to the three-expansion steam engine in the science and technology library. After basic industrial capabilities, many machinery manufacturing becomes easier. Only qualified accessories are needed, and some machinery can be successfully manufactured. The only thing that needs to be strengthened is the accessories. Strength and precision.

Lin Wentao breathed a sigh of relief upon hearing this. The three-expansion steam engine was finally qualified. Ever since Xiao Ming was staring at the laboratory, everyone was now tense, in order to complete the goal as soon as possible.

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

Now every time they meet with officials, they no longer have a slight tone of contempt, on the contrary, they are very envious.

Yes, Your Majesty, I will arrange for craftsmen to build a triple-expansion steam engine when I go back. However, what is the task of the research laboratory below? Lin Wentao was looking forward to them.

Xiao Ming hesitated for a while. In fact, for him, the three-expansion steam engine was just the beginning. This type of steam engine was just the simplest multi-expansion steam engine.

In the field of steam engines, Lin Wentao still has a long way to go, and the multi-expansion steam engine is the next step to 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 achieved, advance technical reserves are still necessary.

So he said; Continue the development and improvement of the multi-expansion steam engine. If you have the energy, you can consider the steam turbine. It is a revolutionary power machine for both ships and electricity.

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 the current industrial capacity of Qingzhou cannot be produced.

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