The steam engine will inevitably be replaced by a more advanced internal combustion engine, this is the process of history, Lin Bei originally thought that it would take a long time, but when he saw this water drawing engine, Lin Bei felt that this process might not take long.

Lin Bei didn't know how to make an internal combustion engine, but after seeing the water drawing engine, Lin Bei saw a hint of direction.

"Wood, seeing this way of drawing water, I suddenly thought of an idea, you come to help Lord Ben improve it, by the way, Zhao Gou, and you too." Lin Bei said.

Everyone nodded.

"The advantages of this water drawer must be obvious to everyone, it can suck out the water in the deep well on the flat ground, which Zhao Gou has done very well, and Lord Ben wants to praise him." Lin Bei praised Zhao Kuo first, and then said: "The disadvantage is that every time the water drawer has to be refilled with steam after pumping and releasing water, the water drawing speed is actually not fast, right." ”

Mu Tou glanced at Zhao Gou, and then nodded: "Yes, my lord, the water drawing speed of the water suction machine is indeed not fast, and it is not comparable to overturning." ”

Zhao Gou also nodded honestly: "What the adult said is right, the villain is convinced." ”

"Well, with this water drawer, Lord Ben has thought of another way to draw water, can you not add steam to the steel ball? And just heating the outside of the steel ball, will this have the same water absorption effect? ”

Heating in this way can also form a vacuum in the steel ball, which will naturally have the effect of absorbing water, but the craftsman has not yet formed the concept of vacuum, so Lin Bei needs to describe this concept in words.

The wood and the surrounding craftsmen thought about it carefully, but they didn't dare to be sure, but immediately tested it, and the result was really as Lin Bei said, it could also absorb water.

So Lin Bei said again: "This method has been proven to be feasible, in fact, this is called vacuum theory." Whether it is to use cold water to pour steam or heat the steel ball, the ultimate purpose is to make the steel ball form a vacuum state, the external pressure is greater than the pressure in the vacuum, not so much the steel ball absorbs water, but the water automatically gushes into the steel ball, do you understand? ”

Lin Bei set aside time for the craftsmen to digest. Then he continued: "Now there is only one steel ball, and the water absorption and water will lead to the vacuum state in the steel ball and the outside to form a balance, so wood, can you add a few more steel balls, and then study them carefully, for example, a steel ball is specially piped to inject steam or heat, another steel ball is used to absorb water, and there are steel balls used to store the water that is sucked up and facilitate the release of water, just like a steam engine." So that they can absorb and release water all the time. ”

The wood and the craftsmen thought about it, and suddenly realized, and at the same time their faces showed excitement, if they really made this, it would be like a rollover, and the water could be drawn out of the well endlessly, because it was powered by a steam engine, and there would be no need for manpower.

"How. Think of the benefits, right? In addition, this method can also be applied to steam cars. You know, suction is also a kind of power, as long as the power is enough, it can also make the car move like a steam car, maybe it will run faster than a steam car. Lin Bei concluded.

If the craftsmen can do it, they will almost make the internal combustion engine. Compared with the steam engine, the internal combustion engine has more power, higher conversion efficiency, and at the same time, it can be used in a wider range of places. If the internal combustion engine can be perfected, even the cars and airplanes of later generations can be made.

"This speed is simply too fast, this is against the sky, if you can make an airplane in ten years, then what will you do in the future? Do you want to conquer the galaxy? This picture is so beautiful, Lin Bei said that he didn't dare to imagine it.

If there is an airplane, it will not take a year for Lin Bei to conquer the earth, and after two thousand years, Lin Bei can't imagine what the level of science and technology will be.

"My lord, we will work hard to achieve the kind of thing that adults say." Mu nodded and said very excitedly, for these craftsmen, the place where their value can be reflected is here, as long as there is a research direction, they will be full of motivation.

"Well, work hard, make this water drawer better first." Lin Bei instructed.

Lin Bei finally left the craftsman workshop satisfied, he was really satisfied, he could know the future development direction of science and technology, and the craftsman would follow his instructions to do it, this feeling of leading science and technology was really good.

"If electricity were to be manufactured, it might not take even a hundred years, or only a few decades, to reach the level of technology at the beginning of the twelfth century."

This night, Lin Bei had no sleep all night.

On the second day, Lin Bei sent a sergeant to bring Zhen Ping to the academy, and asked Bian Ji to arrange for Zhen Ping to teach the students.

In fact, Zhen's business is very simple, very much like a modern chain store business mode, all Zhen's business houses are opened in some states and counties of the big city, convenient transportation has formed a unique news channel, Zhen's business bank usually communicates with each other, if the grain price in which state rises, the nearby Zhen business bank can quickly transport the grain over, grab additional wealth, just like a snowball, Zhen business bank will roll bigger and bigger.

A large number of commercial houses are the foundation of Zhen's in this era, and now Zhen's is not only engaged in rice and grain business, but also involves many other industries, Zhen's is like a capital predator, as long as there is a cake of wealth, he will take a bite.

However, the Zhen family is not without shortcomings, the most obvious thing is that he needs to rely on the strong candidates, and he can't be too conspicuous, for example, now the Zhen family is funding Yuan Shao, Lin Bei knows, but many heroes in the Central Plains don't know, the reason is because the Zhen family does not have a strong armed force, the Central Plains heroes need Zhen's financial resources on the one hand, but they have scruples about Zhen's financial resources, and it is just enough to have money, if there are a few more armies, then these candidates will not be at ease, and they may sweep the Zhen family in minutes.

"Whether Zhen can continue depends on the attitude of those in power in the future, and perhaps this is the reason why Zhen can't wait to bet." After thinking about it clearly, an idea rose in Lin Bei's mind.

At noon, Zhen Ping came back from the academy, and Lin Bei summoned him into the city lord's mansion again.

"Shopkeeper Zhen, what do you think of Nanyue Academy?" Lin Bei asked with a smile.

"Adults are amazing, you can know a thing or two from the academy alone, such a huge academy is really the first in the Han region, but my lord, why are there still young girls among those children?" Zhen Ping asked very strangely.

"What about girls?" Lin Beizhan smiled and said: "As far as Lord Ben is concerned, there is no difference between men and women, they are all the children of Lord Ben, and women are not only married to their husbands and children, such as Cui Lan, Cui Lan is Lord Ben's General Chenlong, who fought for Lord Ben in all directions and made great achievements, such a woman is not inferior to most men in the world, and the shopkeeper Zhen thinks so." ”

Zhen Ping thought about Cui Lan, and had to admit that what this adult said was indeed right, as for what broke the etiquette, this Dragon God Lord could even appoint a female general, and it was actually not so surprising that girls were enrolled in school.

Then, Lin Bei changed the topic and said: "Today, what the shopkeeper Zhen said to those students, after listening to it, Master Ben also felt deeply in his heart. ”

Zhen Ping is not surprised, this is Lin Bei's territory, what class he taught, this adult will definitely know if he knows.

Lin Bei continued: "After listening to the words of the shopkeeper Zhen, Lord Ben knows that it is indeed not a fluke that the Zhen family can have today, and now that the territory under the control of my Great Dragon King Sect is increasing day by day, Lord Ben has some ideas, that is, to set up some institutions in the city under his jurisdiction, just like the Zhen family firm, what do you think?" ”

"Do you also do the rice business?" Zhen Ping asked.

"For example, there is an institution, I call it a bank, it is called Longshen Bank, similar to a money bank, each bank stores a large amount of money, and communicates with each other, if the common people deposit money in the bank in Wanghai City, go to the Longshen Bank in Linjiang City, as long as they rely on the certificate, they can also withdraw money at any time, what do you think?"

Zhen Ping thought for a while, and then his face showed surprise, "The method of adults is very novel, if there is such a bank, it will be too convenient for businessmen." ”

Zhen Ping keenly saw the benefits of this bank, like Zhen every time he came to Wanghai, he needed to bring a large amount of red gold, which was extremely heavy, not easy to carry, and he had to beware of bandits, so he had to need a lot of guards every time, which increased the cost of the merchant in disguise, if there was such a remote access function of the bank, the number of people required for each merchant would be much less, and the farther the distance of the merchant, the greater the benefit for the merchant.

Lin Bei smiled in his heart: "Shopkeeper Zhen thinks this method is feasible?" ”

"This method is very wonderful and indeed feasible, and Zhen Ping is deeply admired."

"Then Shopkeeper Zhen, if it were up to you to carry out this plan, would you be willing?" Lin Bei looked at Zhen Ping with blazing eyes.

"My lord, what is this?" Zhen Ping asked in surprise.

"As you think, Lord Ben wants to recruit you, because Lord Ben thinks you are a talent, so Lord Ben wants to give you a chance, you can copy the successful experience of the Zhen clan in the city under the jurisdiction of the Great Dragon King Sect, and then Lord Ben will improve it."

Zhen Ping said with some trepidation: "Adults are loved, it's just Zhen Ping"

"Don't be in a hurry to refuse, think about it carefully, to be honest, this matter is not unavoidable, this Lord can do it by finding some people casually, Zhen Ping, this is an opportunity for you, Lord Ben's goal is not only the Central Plains, but also the countless foreign countries, the Dragon God Bank to be built will not only be dozens of hundreds, but tens of thousands, your Zhen's nearly 100 commercial banks, in fact, are really not many or big." Lin Bei said frankly.

Zhen Ping couldn't say anything if he refused, he was thinking about it seriously, because as Lin Bei said, Lin Bei was giving him a chance, and it depended on whether he could seize this opportunity. (To be continued......)
