In fact, everyone couldn't wait to give it a try, Duanmu Rong didn't push back, and let people burn the steamer as soon as possible, and soon, the raging fire ignited, and the fire rose, covering the entire bottom of the pot.

At present, there are actually people in Daqin who have used coal, which is called black stone, but the black stone is different, the purer black stone is fine, there are not many impurities when burned, and the natural toxic gas is almost negligible, but if it is a black stone with more impurities, many people may die at any time.

Of course, there are manpower in the Great Qin Weapon Manufacturing Office, so it is natural to find relatively pure black stones, although it has not been processed, the effect of burning fire is still leveraged.

Soon, the water in the boiler was boiled, and the steam rushed to the upper boiler through the pipe, and immediately the slightest missing steam came out, which was caused by the lack of rigor manufacturing, but it did not hinder the operation of the boiler.

No one could see that the vapor had reached that point, but to touch it made the fingers hurt.

At this point, the bar moved, and slowly climbed upwards, as if it had been floating at the beginning, but much faster.

Li Zhao knew that it should be Duanmu Rong who improved the bars in the boiler.

This bar and this pot, if you use modern terms, are cylinders and control valves.

When the bar rose to a new height, Duanmu Rong instinctively wanted to reach out and squeeze it, but was stopped by Li Zhao.

"You don't believe you can improve well?"

Duanmu Rong was stunned, and her hand immediately paused in the air, but her heart was nervous and excited.

Click!

The bar stopped rising, accompanied by a sound, followed by a 'sizzle' sound of air leakage, and in the amazed eyes of everyone, the bar actually changed its direction, sank downward, and slowly returned to its original position.

Everyone was even more nervous, and it seemed that everyone had a question on their faces: the bar had replied, could it be raised again? What's the use of rising?

No one could give an answer, but the truth was that the bar would rise again without hindrance.

In other words, the bar moves up and down successfully, and there is no need for human operation.

Duanmu Rong clenched her fists excitedly, her delicate body trembled slightly, and Li Zhaodu beside her could see the trembling of her clothes.

The corners of Li Zhao's mouth twitched, and his white teeth grinned.

The fact that a person who is so committed to studying can show such a performance proves how excited she is inside, or rather, it is an experience she has never experienced.

The Mohist mechanism is famous in the world, as the core figure of the Mohist, what kind of organ has not been seen, but it is the first time to use the air to promote, this is an innovation, the innovation of the Mohist.

In the history of the Mo family, it is definitely a pioneering existence.

At this moment, her eyes quietly looked at Li Zhao, and she felt that this excessively young man was so tall and wise, if it weren't for his suggestion, she wouldn't have succeeded in the transformation, let alone know that the original anger could also be used like this.

In the Mojia Organ City, the power of all the organs depends on what, relying on water power, water power is everything, but there is a limit, it is not available everywhere, but it is different, no matter where, as long as it can burn fire, it can be used, and it seems that it can be moved.

What does that mean, it means too much.

The bar rises and sinks, and then repeats.

Li Zhao knew that the piston movement was completed, which was a crucial step, and the success of this step would lay a solid foundation for the emergence of the steam engine.

"Sister Rong, what should we do next? Is this the principle of steam ball, we have succeeded? A craftsman asked excitedly.

At this moment, everyone's heart is full of anticipation and the desire to challenge Confucianism.

"This." Duanmu Rong still couldn't believe her eyes, and said uncertainly, "You should have succeeded!" ”

"As for what's next? Let me think about it. ”

Yes, the innovation that will be brought about by the operation of the piston is only known to Li Zhao, and the concept in their minds is vague, or at all.

What can the up and down movement of the bar bring? No one has a thought in their minds, so they can only watch quietly, occasionally falling into deep thought.

"Don't think about it, I'll tell you."

Li Zhao didn't want everyone to delay time, so he simply said it, which would reduce their trying process and greatly shorten the time, after all, the time left for the competition between Confucianism and Mohism was very limited.

From the appearance of the prototype to the maturity of the steam engine, it has taken a hundred years, and if they really let them explore it on their own, he will already be old.

"You know?" Duanmu Rong's gaze fell on Li Zhao again, and this time she looked at it very carefully, as if she wanted to see Li Zhao through.

Han Shaofu also showed surprise and stared at Li Zhao curiously.

He thinks that the enlightenment of the steam ball is almost at this time, and it can be handed over, but at this moment, Li Zhao still has to tell, he can't think of what else Li Zhao can tell, so what does he know?

Everyone looked at Li Zhao with expectant eyes.

Li Zhao smiled embarrassedly and said, "It's not difficult to follow. "He didn't break it right away, but told everyone to go outside.

When he came, he remembered that there were several carriages parked outside.

"Have you seen that these carriages can only walk if they are attached to their horses, but with what they have just realized, they can abandon their horses and make their carriages walk."

What?

As soon as this remark came out, everyone was shocked.

This speech is a bit shocking, but in fact, their expressions are the same as when Ying Zheng heard Li Zhao's heart.

This, this, how can you get it, it's a carriage, how can you walk without a horse? It's a bit of a fantasy.

However, no one questioned it, but listened quietly, looking forward to Li Zhao's next explanation.

"You don't believe me?" Li Zhao saw everyone's expressions, the corners of his mouth rose slightly, and continued, "It's not just a carriage, it can allow all carriages to walk together, and there is no need for a horse. ”

Yes, modern trains are connected by carriages, driven by the nose, without any external force.

This was the beginning of the train.

When everyone heard this, they showed even more absurd expressions.

A carriage is amazing enough, and now all the carriages can be walked in tandem, which is probably only available in the world of immortals!

Li Zhao didn't explain much, walked into Han Shaofu's office alone, found paper and brushes, and bought a steam engine manufacturing drawing from a department store.

The steam engine is mainly composed of cylinder, base, piston, crank connecting rod mechanism, slide valve distribution mechanism, speed regulating mechanism and flywheel.

What was invented just now is only the cylinder and piston, and if you want to make a steam engine, you still need a lot of parts, Li Zhao only understands the operating principle of the steam engine, but he doesn't know much about other components, and only by buying can he solve the current needs.

After a while, he walked out, handed over a piece of paper with various structural drawings drawn in it, handed it to Duanmu Rong, and said:

"The thing you just realized is called a steam engine, but it is only a prototype, and it is not perfect, but the vested principle must be able to make a real steam engine, and these drawings are the drawings of the various parts of the steam engine, and you can make it and put it on the carriage, and you can push the carriage."

"Of course, the carriages you see now are too fragile and too small, and I speak of carriages the size of a house that can hold a lot of things."

"I'll call it a carriage, and in order to save time, after you have built a steam engine, let's build two carriages first!"

There is no way, to make a multi-carriage train, less than a month is simply not enough, although they have a lot of people.

The only way to do this is to downsize.

Of course, even if it's just two carriages, it's enough to amaze the entire Daqin.

"Steam engines? Carriage? Everyone became more and more confused when they heard this, but their eyes quickly focused on the drawings and looked at them curiously.

They are craftsmen, and they are naturally no strangers to drawings, of course, it is completely impossible for them to see through such complex drawings at once, but in a limited time, they should be able to understand them, after all, after so many drawings, Li Zhao's painting has already gone up a level, and the things drawn are not difficult to understand.

"This, it turns out that the bar is used like this, wonderful!" Soon, someone understood, and they were amazed.

"If you put it on a carriage, you might be able to really push it along." Someone believed.

"It turns out that there really is such a divine thing in the world."

When many craftsmen saw it, their eyes became brighter and brighter, even to the point of shooting the case.

"My lord, is this what you call a horror?" Someone thought of something and looked at Li Zhao in horror.

At that time, Li Zhao said that he could create a terrifying thing by realizing that the steam ball could be made, but everyone thought it was too ridiculous to take it to heart, but at this moment, the prototype of the steam engine was made and the drawings were seen, so they didn't think so.

"Of course, this is a horror thing, when the steam engine is successfully developed, it can drive more carriages, and this thing is no longer called a carriage, but a train."

Train?

Everyone heard the new words again, and pondered for a moment.

The next moment, someone was puzzled and asked, "What is a train?" What's the use? ”

"Hey, hey!" Li Zhao didn't point out directly, "If you make it according to my method, you will naturally know it then." ”

When it was manufactured, in fact, there was no need for Li Zhao to say it, they would also know, after all, the horse-drawn carriage had been used as an example just now to explain this point very well.

Of course, the other craftsmen didn't know, I believe Duanmu Rong knew, at this moment, she looked at the drawings, and she was excited again, and her hands kept shaking.

"Also, the steam engine is not only used for this, but also for navigation, it can make the ship no longer need to be rocked by manpower."

Daqin's ships were still in a relatively backward stage, not to mention steam engine ships, even sails had not yet been invented.

It can be said that if a steam engine ship is manufactured, the shipbuilding industry will go beyond the sail era and move directly towards the steam ship, which is a great innovation and a change across the era.

"So that the boat no longer needs to be rocked by manpower? This, this." No one dares to believe it, but they have to believe that they can move without seeing the carriage? That ship might be able to break away from manpower.

At this moment, everyone fell into the hope that when that day came, what it would be like.

Everyone was talking enthusiastically, and suddenly, there was a 'snap' sound from the side.
