"There is a Leqing in Kaifeng, the iron-faced selfless discerning loyalty and treachery, the heroes of the rivers and lakes come to help, Wu Song and Yang Zhi are by their side......"

Whenever I heard a child sing this unknown ballad, the people of Biandu all sighed, how could such a good official of Dali Temple Qingle Marquis Shang the emperor become a concubine, and since then he has become an idle person who can no longer serve the court.

Gradually, some words spread among the people, and there were various gossip that the Marquis of Le Dali Siqing did a good job but suddenly became a princess, and there were many insiders in the meantime.

What the insider? Hearing the gossip of these people, the bad people got better.

So all kinds of rumors spread in Biandu, because of the official integrity and not favoritism, he once beat up and fought with the people during the flood in Biandu last year, and became the concubine brother of Wang Huang, the prime minister of the court, and the two were not in harmony; Le Hou Ye is arrogant by nature, and Liang Shicheng, who is known as a hidden appearance in the dynasty, can't talk together, and even impeached and disposed of Yang Jian, the head of the Gongtian Institute, and Yang Jian and Liang Shicheng intersected irreversibly, so that Liang Shicheng was jealous of Le Hou Ye and could not retaliate.

Moreover, Hou Guan also led troops to destroy the Xia Kingdom, and robbed Tong Guan, who was known as the Great Song Dynasty, how could Tong Guan be pleasing to the eye; Previously, Lotte was guilty of the dynasty ruling Cai Jing, and the Cai family also died in Hangzhou in an unknown way, and the Cai family also counted this account in the body of Le Hou Ye, although Cai Jing Zhishi, it seems that Deng Xunwu, Bai Shi, Hu Shi and others are his henchmen, how can he let Le Hou Ye do this official stability.

What kind of beating are these officials and eunuchs in the Great Song Dynasty today, the people of Biandu know very well, so the people are also convinced of these rumors, it is these people who want to cure the Hou Ye but can't grasp the handle of the Hou Ye, so they have no choice but to collude in all kinds of rhetoric in front of His Majesty, so that His Majesty will marry Emperor Maode to the Hou Ye, and from then on let the Hou Ye Le stay away from the court, and they can't hinder these people.

Although there are different versions of the rumors, each version has a very high degree of credibility and is enough to withstand scrutiny.

When the people of Biandu sighed, there were the latest developments of the Le Hou Ye, saying that the favor of the idle Le Hou Ye is different from those other idle princes and horses, one likes to talk about poetry and words in vassals and elegance, the second is not nostalgic for the land of fireworks and dust, and the third is not fond of the sound of dogs and horses, but bought a yard in the distance of Biandu, recruited many fine craftsmen, and indulged in some tricky things.

For Lotte is not attached to the elegant saying, not only the students of Biandu are also ordinary people who sneer, the family Le Hou Ye is the leader of elegance, Le Hou Ye is recognized as the first talent in this dynasty, only others to vassal Le Hou Ye, how can Le Hou Ye go to vassal others.

Some people even say that Lord Le Hou has long been tired of flowers, and now he has no sense of the color of copper flowers......

For these rumors, Lotte just smiled helplessly, his own wife, flat wife, and eleven concubines of all sizes, who can withstand such suppression......

As for the rumors that Lotte is addicted to some technical and clever things, this rumor is true, and recently Lotte has definitely been studying something about machinery.

In the courtyard under it, Lotte recruited many skilled craftsmen, and there were many coppersmiths and blacksmiths who were proficient in smelting, Lotte secretly divided these people into two, and some coppersmiths and blacksmiths were secretly sent to the Grange where Emperor Maude married, and at the same time ordered Tu Si's subordinates to be stationed around the Grange, on the surface, the Grange was inconspicuous, but in fact, this Grange was loose on the outside and strict on the inside, and the inside was Lotte's workshop for making artillery guns.

As for the other part of the craftsmen, Lotte placed them in another annex with great fanfare, which was public, and Lotte announced that these craftsmen were invited to make steam engines.

This annex was not far from the Grange where the artillery guns were made, and the distance between the two was only Rich.

Today's Lotte has unloaded the Dali Temple, only hanging the false title of the Marquis of the Three Pins and the Captain of the Horse, except for the great court that has a very formal need for these nobles to fill the façade, even the court does not want it, Lotte is now very comfortable.

The craftsmen recruited are all skilled craftsmen who are well-known in various places, and since they have been recruited, it is natural for Lotte to ask these craftsmen to meet and explain their intentions.

Different from later generations, in later generations there are craftsmen with unique skills are sought after by the world, in the era of the Northern Song Dynasty, the status of craftsmen is still low, I heard that the famous Le Hou Ye wants to see his own people, the excitement of the craftsmen can be imagined.

After seeing Lotte, a group of craftsmen found that this marquis, who was a high-ranking man and married to the emperor, not only did not have the slightest shelf, but also smiled and looked very approachable.

After seeing the ceremony, after a polite and not much to say, in the attention of a group of craftsmen, Lotte began to talk about what a steam engine is, as well as the principle of a steam engine.

What is a steam engine, no one has ever heard of it in this era, and no one has ever seen it, everyone's first reaction when they hear the word steam engine is full of confusion, when Lotte gathers these people together, talking about the function and principle of the steam engine, he was shocked.

As long as coal can run automatically, this is a fantasy and unheard of for people in this era.

Optimistic heart with the thinking of later generations has long been prepared, this advanced concept is contrary to the cognition of people in this era, but Lotte ignores a point, although the Song people are backward in cognition, but the ability to accept is quite strong, in this regard, the Song people and the Ming and Qing dynasties are different from the people of the Ming and Qing dynasties who are in a closed country and self-isolation.

First of all, these craftsmen will have a cognition in their hearts, who is the person in front of them, it is the famous Le Hou Ye who is the official of the dynasty, and he is the first wind and talent of the Great Song Dynasty, and he is the master of the Great Song Dynasty.

In order to make these craftsmen understand what they are saying, Lotte also spent a lot of thought and effort, when Lotte finished talking about the steam engine, he began to explain from shallow to deep, first talking about the most basic waterwheels and windmills.

Waterwheels, windmills, whether it is to draw water or to grind noodles, since the invention to the Song Dynasty in China has a history of more than 1,000 years, these craftsmen have seen it before, naturally they can understand it, and even many people are experts in this area, but also know the principle in the meantime, and have a strong interest in machinery.

After explaining the principle of the waterwheel windmill, Lotte Shakutanchi brought a stove and a special sealed thin-spout kettle, poured the kettle into the stove, boiled the water in the kettle until it boiled, and brought an ordinary windmill made of fine and used as a toy by children, and put the windmill in the thin mouth of the kettle that sprayed steam, and then the steam spewed out by the windmill in the kettle spun up quickly.

Because the thin-spout kettle is well closed, all the steam is sprayed out of the spout, and the steam is not only hot but also powerful, and the speed of the windmill is getting faster and faster.

Looking at the spinning windmill, Lotte smiled and looked at the craftsmen, "You can see it clearly, this is what Le said about the principle of the steam engine, burning coal converts the heat of fire into boiling water vapor, and then uses the windmill to convert the energy of water vapor into mechanical energy, just like a fire wind and water wheel, so as to drive the operation of machinery." ”

No amount of saliva is just a practice, looking at the small windmill spinning in steam, the craftsmen immediately understood the principle.

Knowing its principle, a group of craftsmen couldn't help but throw themselves to the ground with the five bodies that Lotte admired, and Lotte's idea was really a wonderful idea, which no one had thought of before.

Seeing the sudden expressions of the craftsmen, Lotte continued: "You understand the principle, but you don't just understand it, Le wants to make this principle a reality, as long as Le's idea becomes a reality, in the future, I will no longer need to see the sky with the help of sails, nor do you need manpower to row or use a slender man, and even the road vehicles do not need horses to pull." ”

For people who have no mechanical common sense in this era, Lotte's statement can be described as absurd, but after a group of craftsmen understand the principle of the steam engine, they have begun to not doubt what Lotte said, and even under the influence of Rakuten's words, everyone's mind has sketched a huge blueprint......

"Ladies and gentlemen......" As the craftsmen were thinking about it, Lotte's words brought the thoughts of the tools back to reality.

Seeing that a group of craftsmen turned their eyes to themselves, Lotte continued: "Everyone, although Le said that the sky is wild, but there is a folk saying that 'useless is a scholar', although Le has this idea, but he is a scholar who has no power to tie the chicken, and he does not know the doorway in the craft industry, so if Le wants to turn his idea into reality, he cannot do without your assistance......"

"The little one is willing to serve the Hou Ye for the work of dogs and horses!"

"Master Hou, what do you say, how do you do the small one, and the small one will desperately turn Master Hou's idea into reality."

……

After Lotte's words fell, a group of craftsmen expressed their positions one after another.

Lotte also arched his hand and said, "Le depends on you!" ”

The original engine of the steam engine is very simple, it is a reciprocating power machine that converts the energy of steam into mechanical work; The steam engine needs a boiler that boils water to produce high-pressure steam, which can use coal, wood, and even combustible garbage as a heat source to expand the vapor and push the piston to do work.

Although it is not mechanical, Lotte has read a lot of knowledge about history and economy in the textbooks of his previous life, and the emergence of the steam engine directly caused the industrial revolution in the 18th century, which has a non-negligible role in the promotion of economy and history.

However, although the idea and ideal are good, but the idea and ideal are subject to the constraints of reality, first of all, there is a hurdle to overcome the past, but also have to face the fact that the manufacture of steam engines requires excellent steel, and the current output of ordinary steel in the Great Song Dynasty can meet the requirements of manufacturing machinery.

Steel!

All assumptions are back to square one, and high-quality steel and production capacity are the biggest constraints on productivity.

This was not only in later generations, but also in the Great Song Dynasty at this time, and it was also the biggest factor restricting productivity.

Without high-quality steel, let alone a steam turbine, it is an artillery, and I am afraid that it is also an empty mansion.

How to refine steel with high performance has become the biggest headache for Lotte.
