When Fries led a group of scholars of the Greek school to Broken Leaf to join Li Lu, among them, there was a descendant of the ancient Greek scientist Hero, Riotinis, who once showed Li Lu a strange machine that was absolutely a strange skill in the eyes of the scholars and doctors in the Central Plains, this machine was called "Steam Ball", the structure of this "Steam Ball" was very simple, it was connected by a hollow ball and a closed pot filled with water with two hollow pipes, The water added to the bottom of the pot boils and then turns into water vapor, which then enters the ball through the tube, and finally the water vapor is ejected from both sides of the ball and causes the ball to rotate.

At that time, Li Lu was quite shocked when he saw it, in his opinion, this is not just a delicate toy, but the most primitive steam engine, he said to those scientists that if the time comes, steam power will inevitably prevail, and this small "steam spinning ball" may trigger a power revolution, he hopes that someone can continue the research of Hiro, at the same time Li Lu also offered a reward, if anyone can put the steam power device into practice, he will let him gain fame and fortune.

From then on, Riotinis and his students from Broken Leaf University, as well as some of the best inventors in the people, all focused their energies on what Li Lu called "steam machines", and even Daomen and Mojia, as well as scientific giants such as Song Yingxing and Shen Kuo, were involved.

The first to gain was a Taoist doctor, this Taoist priest named Yunping because he wanted to make a high-pressure vessel suitable for disinfection, he got a copy of Hiro's "Mechanical Collection" from Riotinis and Hiro's invention of chain pumps, air pumps, piston pumps and other machines, called his friend, Xiang Libin of the ink door to study together, as a result, the two of them developed a strange container, when they dedicated this to Li Lu, Li Lu said in surprise, "Isn't this a pressure cooker??" ”

Yes, this strange container invented by Yunping and Xiang Libin is a pressure cooker, the most critical part of the pressure cooker is the safety valve, the two of them ingeniously invented a lever safety valve, which applies a heavy object at the far end, and the force point of the steam pressure to push the steam valve is a short force arm, when the pressure of the pressure cooker exceeds the design value, the steam valve can be pushed up to discharge part of the pressure, and then fall back to the distance after balancing. When he saw this safety valve, Li Lu said that he could make a piston steam engine on the basis of this safety valve, although Yunping and Xiang Libin did not put Li Lu's idea into practice, but they spread Li Lu's conjecture.

After Song Yingxing and Shen Kuo visited the pressure cooker built by Yun Ping and Xiang Libin, they carefully studied Li Lu's conjecture and found that this plan was still feasible, but because of the lack of manufacturing technology to make a good closed piston, they abandoned the piston structure in the plan and built a steam engine that could be used in the mines, which was mainly used to help those mines extract groundwater.

Their steam engine was redesigned with two parts: a boiler and a closed working vessel. The working principle is very simple, that is, first add water through the boiler to fill the working vessel with steam, and then close the steam inlet hole, so that the water vapor in the working vessel condenses, forming a local vacuum, when the container is connected to the mine water, through the external atmospheric pressure, you can "suck" the water to a high place, the principle is to rely on the atmospheric pressure to press the water up, so the lifting height of the water is related to the atmospheric pressure, about three zhang. In order to send water to a higher place, Song Yingxing specially designed a steam pressure device to send water to a higher place, this machine was named "Friend of the Mine" by Li Lu, and Li Lu issued Song Yingxing and Shen Kuo two people can be said to be the first steam engine patent in the known world.

This steam engine was used in large quantities by Yinghua Mining, a subsidiary of Wu Mei's Department of Commerce, but this "Friend of the Mine" has many problems, the most important thing is that the efficiency of this steam engine is very low, and it needs to burn a lot of coal in order to maintain the operation of the machine, but fortunately, it is used for coal mine pumping, and coal is. However, it relies on pressure to transport water, and due to the lack of material manufacturing and welding technology, the pipeline breaks and explodes from time to time, and at the same time relies on atmospheric pressure to lift water, and the maximum lifting height is about three zhang, which limits its use range.

Although Song Yingxing and Shen Kuo thought of a lot of ways, but to no avail, just when the two science and technology tycoons were thinking hard, a steam engine repairman named Sun Xin from a Kazhou coal mine solved a problem that neither of them had solved.

Sun Xin only had a primary education, he used to work as a blacksmith in a mechanical workshop, and then by chance, he became a steam engine pump repairman in the Kazhou Coal Mine owned by Yinghua Mining, when repairing the steam pump, he found that the condensation of steam into the lower part of the piston and the piston and the connecting rod can produce movement, he thought that this idea is installed on the "Friends of the Mine" he serves, wouldn't it be possible to form a better machine? Sun Xin is a person with ideas and willing to do it, he first made a scale model, and after finding that his idea was completely feasible, he was ready to get this device out, but the biggest problem came, he was just a maintenance worker, not much money, and his boss sneered at him, saying that even the masters of Broken Leaf University and the Science and Technology Department couldn't solve the problem, you can solve it with a small maintenance worker, and said that he would not provide Sun Xin with funds for experiments.

Sun Xin was angry, and wrote his plan and Yinghua Mining Manager's sneer at himself on a letter, and threw it into Jinyiwei's special mailbox, because Li Lu attaches great importance to scientific and technological inventions, so after seeing Sun Xin's letter, Kazhou Jinyiwei did not dare to delay, and they sent Sun Xin's letter to Broken Leaf quickly.

When this letter arrived at the broken leaves, Li Lu was worried about what excuse he would not go to Chang'an once Li Er hung up, when Li Lu opened Sun Xin's letter, he was surprised to see that the steam engine designed by Sun Xin was already a relatively mature steam engine program, and this plan was more advanced than the previous Song and Shen two people's plans in that the pressure of this machine was no longer limited and the steam pressure, as well as the internal condensation nozzle and automatic valve actuation device on his plan were simply genius-like ideas, Li Lu couldn't help but applaud Sun Xin's design.

But when Li Lu saw Sun Xinfa's prison, he couldn't help but be furious, "These bastards, they can't do it themselves, and they still have the face to ridicule others......" When Li Lu was angry, it happened that Wu Mei walked in, she was holding a cup of strong coffee, "What's wrong?" Lang Jun, who you off? ”

When Li Lu heard Wu Mei's voice, his anger calmed down, and he pushed Sun Xin's letter in front of Wu Mei, "Mei Niang, look at it, your good subordinates..."

"My good men??" Wu Mei was taken aback at first, she took Sun Xin's letter, quickly skimmed it, and then became angry, "This Qin Bo is really a bastard...... Lang Jun, I will sign an order to remove him from his post...... "Yinghua Mining is a directly subordinate enterprise of the Department of Commerce, and Wu Mei naturally has the right to remove this Qin Bo from his post.

"Mei Niang, you have to check this Qin Bo well, well, and our stall is getting bigger and bigger, and some problems will inevitably appear, it's not terrible to have problems, it's terrible not to solve them......" Li Lu took a sip of coffee, "You have to investigate and deal with Qin Bo's matter, and rectify the business under our family name and Wang Ting's name..."

These enterprises mentioned by Li Lu are roughly quite state-owned enterprises in later generations, and after a long time, some problems have also been used to appearing, such as this Qin Bo is an excellent example.

"Well, these people are actually moths, if they go to eat others, I Wu Meiniang can't control it, and I don't want to take care of it, but I want to make a living under the banner of the two of us, and I still want to be moths and dig the corners of our family, this is what my Wu Meiniang can't accept..."

Soon Sun Xin was taken to Broken Leaf with his drawings, and Qin Bo, who was sneering at him, also found that this guy was not only incompetent, but also greedy, and he was guilty of all the crimes he could, except for the crime of collaborating with the enemy, when he searched his house, people were surprised to find an astonishing amount of gold and silver in the wall of his house, and when Jinyiwei interrogated him, this Qin Bo actually said that because the flying money was easy to find, all the stolen money he took bribes and embezzled was replaced with gold and silver......

Qin Bo's fall heralded the arrival of a new wave of anti-corruption in the "state-owned enterprises" of the British Kingdom controlled by Li Lu, but their owner Li Lu did not put his mind here, but pulled Sun Xin and Song Yingxing, Shen Kuo, Riotinis and a large number of experts began to tackle the steam engine, it turned out that the steam engine Li Lu wanted was not this kind of steam engine that was only used to pump water, he wanted the kind of steam engine that could be widely used.

"We can design a separate condensing device, so that there is no need to reduce the temperature of the cylinder to room temperature and then re-add it, maybe we can improve the efficiency ......of the machine," Li Lu said to a group of scientific and technological giants, "I suggest that Sun Xin's plan continue to be improved..."

"There's also the question of the drivetrain... You see, the way of motion of my scheme is that the piston is doing reciprocating motion, how to turn this reciprocating motion into a motion that can rotate, this is a big problem...... "This is Sun Xin."

"Well, we can use cranks and gears to design a transmission system and accept the work ......done by the piston," Song Yingxing thought about it and said.

"We can also design the cylinder to be bidirectional, so that the air intake on both sides of the cylinder will definitely improve efficiency..."Shen Kuo is not far behind.

"If you want to run a two-way cylinder smoothly, a parallel four-rod linkage is indispensable...", Riotinis also put forward his own opinion.

In the end, with the efforts of Li Lu and several science and technology masters present, an epoch-making machine was tossed out by them, the appearance of this machine marks that Li Lu has opened the door of the industrial revolution, just when Li Lu was too happy, he didn't pay attention to the system for a long time, but reminded him, your civilization point balance is not much, please hurry up and recharge, Li Lu quickly logged in to the background to check, don't look at it I don't know, I was startled when I saw it, it turned out that because of the appearance of the steam engine, the system must be upgraded, And the civilization points required for upgrading are an astronomical amount, and this number is so big that it can eat him, what should I do??

What is the fastest way to get money? This still needs to be asked, naturally it is robbed, it seems that it is time to start a war again, thinking of starting a war, Li Lu's mind lit up, he came to the expedition himself, if Li Er hangs up, he doesn't have to go to Chang'an. I want to talk about "Rebirth of the Tang Dynasty as a Khan" with more like-minded people, and "chat with more book friends about your favorite books."
