Li Xuan's three in a row made Lin Hui feel a little surprised, although this steam engine is difficult to come up with, and it is also very novel, but to be honest, he who is the developer of the steam engine in the organizing committee does not understand why His Majesty attaches so much importance to the steam engine.

As for the term industrial revolution, it was the first time he had heard it, and he really didn't understand what the industrial revolution was!

He engaged in the steam engine, on the one hand, because he was very interested in this kind of machine that can run by itself by relying on coal, and had great curiosity, and on the other hand, it was also because of Li Xuan's fate, Li Xuan attached great importance to the steam engine, and naturally hoped that Lin Hui could make a steam engine as soon as possible.

Today, after getting the steam engine out, Lin Hui also felt that his dream had come true and satisfied his curiosity, but for him, it was just to satisfy his curiosity, as for what this steam engine was for, to be honest, he also knew a little bit, it was nothing more than as a new power.

But he didn't know how much of a role the steam engine could play as a new power.

After the test steam engine finished its test operation, Li Xuan looked at the steam engine that was still emitting heat, and his eyes were like looking at a super beauty, and he almost drooled.

Then he directly called Lin Hui aside and asked some detailed technical questions about the steam engine, which was nothing more than the difficulty of production, whether it could be mass-produced, how much power it had, whether it could be improved, and a series of questions such as how much power it could be improved.

From Lin Hui's mouth, Li Xuan also had a general understanding of the overall performance of this steam engine, because this steam engine was developed on the basis of previous generations of steam engines, so the operation of this steam engine is relatively successful, and it can output power stably, and this power can directly drive other machinery that needs to be driven, such as machine tools, such as pumping machines, etc.

The steam engine itself is just an engine, and how to use it is actually a matter of follow-up design, and Lin Hui basically doesn't care about this aspect.

In terms of power, this seemingly huge steam engine is only five horsepower, and in order to obtain this three horsepower, a lot of fuel is required.

From the perspective of later generations, the technical level of this steam engine could not be lower, but for this era, it is enough to be called an epoch-making invention!

Even if it's just five horsepower!

Li Xuan, who was extremely excited about this, summoned other senior students in the young military camp on the spot, and personally assigned research and development tasks to them, Lin Hui's task was naturally to continue to specialize in steam engines, reduce the volume and weight, increase the power, and simplify the design for mass production, these are Lin Hui's tasks.

Others, on the other hand, were given other R&D tasks, such as pumping machines, etc., mainly in the application of steam engines.

Li Xuan hopes that in a short period of time, the steam engine will be used in industrial production, especially in the production of minerals that require a lot of manpower, and it will also need to be used as factory power to replace the water power that is currently widely used.

At the same time, there are also military applications, the most important of which is to put a steam engine on a ship and build a steam ship!

For this reason, Li Xuan even personally designed the style of paddle steamer boats, and directly asked these people to create steam-powered paddle steamer boats.

As long as it can be built, it doesn't matter if the horsepower is smaller!

It doesn't matter if it's good or not, just use it!

The appearance of the steam engine made Li Xuan feel very good, and he even announced on the spot that he would reward Lin Hui with 1,000 taels of silver, and at the same time grant him the title of viscount, and his daily treatment would be compared to the three grades.

In Li Xuan's opinion, Lin Hui's talent is more important than other third-grade officials, but Lin Hui is not an official after all, and he is also very young, this academic boss in the Tang Dynasty is actually only nineteen years old!

Lin Hui was given the award, which also made Chen Ziran on the side envious, jealous and hateful, and after going back, he plunged into the steelmaking Dafa, but unfortunately, the difficulty of mass production of steel is higher than the research and development of steam engines, and after Chen Ziran fell into this sinkhole, it is unknown when he will be able to climb out.

After leaving the steam engine, Li Xuan's good mood was still difficult to calm down, and he didn't go to deal with official business in the afternoon, anyway, everything was like that, and there was nothing to delay a little, and in the afternoon he rarely accompanied Empress Dong and Empress Dowager Bai's family to watch a happy drama.

During this period, Princess Huichen also heard Li Xuan talk about the steam engine outside, and she was also very interested in it, clamoring to take a look, but she was glared at by the Empress Dowager Bai, and she was scared back.

Princess Huichen, who has a large tonnage, is naturally nothing in front of the white queen mother, who has a larger tonnage!

However, for this sister, although Li Xuan didn't care much, after all, she was her own sister, so she also said a few words on the side, saying that if you want to see it, let the grandmother in the palace accompany her to see it another day.

Then I asked two more questions about Princess Huichen's reading!

It's a pity that this princess Huichen has no talent for reading, although she is literate, but it is only limited to the scope of literacy.

However, being able to read is also better than not being able to read big characters before!

After asking a few words slightly, Li Xuan nodded slightly, and then said: Only by reading can you be sensible, and you still have to study hard in the future!

Li Xuan doesn't want that the eldest princess of the Tang Dynasty is a fat woman who doesn't learn and doesn't know how to do it, and this tonnage can't be reduced, but the words must be recognized, and the book can be understood, otherwise, it will not be her face that will be lost, but the face of his Tang royal family.

After watching a drama, Li Xuan accompanied Dong Yunyun's mother and daughter for a walk, and personally took a walk with the tender Princess Wei'er on the whiteboard, but Princess Wei'er was still too young, she was held in Li Xuan's arms when she was less than a year old, and she looked extremely excited.

And a pair of small hands are also very strong, pulling the hair hard, making Li Xuan's painful face change, and he said: "Little ancestor, light, again, your father's hair will have to be pulled out by you!" ”

Princess Vile seemed to understand him, or because she thought it was funny to pull her hair, she immediately let out a giggle.

When others looked at this look, they all had strange expressions on their faces that wanted to laugh, but they didn't dare to laugh!

If the ministers of the outer court knew that the Son of Heaven, who made them feel more and more moody and even frightened, was bullied by Princess Wei'er at this time, they would probably be shocked by their big teeth!

After hugging and turning around, Princess Wei'er was handed back to Dong Yunyun, and the strange thing is that after Princess Wei'er returned to her mother's arms, she immediately became a lady, not noisy or noisy, obediently held, looking east and west with a pair of super big eyes, without blinking for a long time.

After having dinner with them, Li Xuan also rested directly on Dong Yunyun's side that night, and Dong Yunyun was very happy and even excited about Li Xuan's stay.

You must know that although Li Xuan often came to visit Princess Wei'er and her, Princess Wei'er was at the front, and she, the queen, had actually not been favored for more than half a month.

There is no way, there are too many women in the harem, and they can be sent to Li Xuan, all of them are purple and are high-quality and versatile women, Li Xuan is not a decent gentleman, it is normal to be fascinated by those fox spirits and then forget Dong Yunyun.

Of course, even though Li Xuan doesn't often stay with Dong Yunyun, he hasn't shaken Dong Yunyun's authority in the harem at all!

Dong Yunyun is still the queen, and she is also the queen of real power, the most powerful in the huge harem is the Empress Dowager Bai, and the second is her!

Among the many affairs of the harem, some important affairs are basically decided by the Empress Dowager Bai, and other affairs are basically decided by Dong Yunyun, if you have to strictly say it, if there is no Dong Yunyun's approval, in fact, Li Xuan can't see those women if he wants to see them.

Because these women can enter the palace and become Li Xuan's pillow people, they all have to pass the handsome selection and approval of Queen Dong Yunyun!

After all, outside the male protagonist and inside the female protagonist, Li Xuan also respects this tradition, of course, this is also because Li Xuan is too lazy to manage many messy things in the harem.

But in any court, palace fighting is indispensable, and with so many women in the harem, this fight is also quite intense.

It's just that Li Xuan doesn't care if he doesn't see it, anyway, as long as these women are extremely deferential in front of him, he doesn't care much about the rest of his thoughts.

Of course, even if he doesn't care about most things, he still personally intervenes in some major events, and it is a very case of prevention, which is the protection of pregnant concubines and the protection of children!

For the protection of children, this can be seen from his protection methods for Princess Wei'er, and this is just a princess, if the prince is born, then the level of protection will definitely be second only to Li Xuan's own!

And the pregnant concubines in the harem, has always been deeply protected, and now several pregnant concubines in the palace are personally taken by the Empress Dowager Bai to protect, and the people who serve them are also their own frequent henchmen and maids, and the Empress Dowager Bai will also appoint her henchmen and aunts to protect her to prevent all kinds of accidents.

Fortunately, so far, there has not been any such a bad thing as poisoning or miscarriage.

But even so, Li Xuan did not relax at all!

The eighth department of the Survey and Statistics Department of the Hanlin Academy is in charge of clan affairs, and at the same time, it does not belong to the Hantong Guan, but only has a name in the Hantong, but reports directly to Li Xuan! Many palace maids in the harem are actually from the eighth place, monitoring many hidden things in the huge Tang Palace day and night.

In recent days, the eighth department has been mobilized, because Concubine Ye and Concubine Wang are about to give birth, these two daughters are very likely to give birth to a prince for Li Xuan and consolidate the country's foundation for the Tang Dynasty!

In this way, it is no wonder that the eighth place is almost like a great enemy!
