Zhang Yan was also very surprised to come closer, stretched out her hand to check the train, on weekdays, she also had a lot of advice to Zhu Youxiao's love for woodwork, and she didn't agree with Zhu Youxiao's abandonment of the court, and she was obsessed with woodworking, but after saying a few times, Zhu Youxiao still went her own way, and she didn't say it again.

When she heard about such strange things at this moment, she couldn't help but check it out, she raised her head, looked at Huang Xiao, and said: "Every time the imperial court transports grain and grass to Liaobian, it will cost tens of thousands of people, ten percent of grain and grass, and fifty percent more for consumption on the road, which not only makes the people tired, but also consumes amazingly, if it can really be so, it can really be said to be the important weapon of the country!" ”

Huang Xiao nodded and said, "If I hadn't studied the mystery thoroughly, I wouldn't have opened my mouth!" ”

Zhu Youxiao got up and bowed down, and said, "Please also ask Brother Huang to give advice!" ”

Huang Xiao sighed: "Okay! I believe in Brother Zhu's character. ”

As he spoke, he dismantled the locomotive, put it in his hand, and said, "The most critical place for this train is in this locomotive. ”

Huang Xiao decomposed one by one, "Brother Zhu, Mrs. Zhu, please look here, this is the combustion chamber, with coal as fuel, here is the boiler, the boiling steam is transported through the pipeline to the intake chamber, pushing the connecting rod, driving the piston rod, and the generated power is transmitted to the wheels, so that it can pull the carriage forward......"

Huang Xiao roughly explained the principles one by one, Zhang Yan and Yueniang seemed to understand it, while Zhu Youxiao listened to it more and her eyes brightened.

Finally, after Huang Xiao finished explaining the working principle, Zhu Youxiao asked, "This should be made of iron, right?" ”

Huang Xiao raised his thumb and praised: "Zhu Gongzi is really talented!" It's iron, and it's good steel. ”

Zhu Youxiao was a little embarrassed to be praised by Huang Xiao, but Zhang Yan said: "The cost of such a huge train and track must be huge, and the imperial court may not be able to come up with so much money to build it, and it is just for this purpose, I am afraid that the gains outweigh the losses, this is the little woman's shallow opinion, Mr. Huang is not to blame." ”

Huang Xiao smiled and said, "Mrs. Zhu's words are not unreasonable, but the purpose of this steam engine is not just a train, this is just one of his small uses!"

If the steam engine is used in agriculture, for example, many places in Daming are affected by drought now, and the steam engine is used to make a pumping machine, which can pump water from the river day and night for irrigation; If there is no nearby water source, you can make a steam engine drilling rig to take deep groundwater, or you can make agricultural machinery such as a cultivator. ”

Huang Xiao took a sip of tea and continued: "If it is used in business, it can provide power for various machinery, and the quality of the goods produced is stable and the output is extremely high. ”

"If it is used on a ship, it can be ignored whether it is smooth or against the current, not only saving time and manpower, but also carrying a large number of personnel and materials...... The uses of this can be said to be infinite possibilities, and if I think about it, I can know that there are many uses that I haven't thought about.

That's why I said that this is the important instrument of the country, and I am referring to this steam engine! ”

Huang Xiao talked eloquently, Yueniang listened obsessively on the side, she was really proud of Huang Xiao at this moment!

It turns out that he is not a fool, but has spent more than ten years studying knowledge and benefiting the public, and he really has a patriotic heart and loves the people!

Zhu Youxiao and Zhang Yan were stunned!

At the same time, the two of them were also very excited, just from the application described in Huang Xiao's mouth, the two of them could think that this small machine could bring earth-shaking changes to Daming.

Zhu Youxiao stood up excitedly and said loudly: "Okay! What a country's most important weapon! ”

After speaking, he took the locomotive from Huang Xiao's hand, touched it again and again, and couldn't help but say, "Good baby!" Ha ha! This is really a blessing for the Ming Dynasty! ”

Zhang Yan was also impressed, and bent down to salute Huang Xiao, "Mr. Dacai, the little woman is really rude!" ”

Zhu Youxiao was also in a mood, and he clasped his fists and saluted: "Mr. Huang really let me ...... I am so impressed! ”

Huang Xiao smiled indifferently and said, "Although I, Huang Xiao, am a grass citizen, I also have a heart to serve the country!" Every time I hear that the people are living in hardship and the border passes are invaded, I can't tell how uncomfortable I feel, so I concentrate on studying, hoping to be able to contribute my own strength to Your Majesty and this brilliant Ming.

This is what I should do as a Ming person, I don't deserve the reputation of the two, and I will be embarrassed to praise me like this! Ha ha! ”

Zhu Youxiao also laughed.

Huang Xiao glanced at the needle in Zhu Youxiao's hand, and hurriedly said: "Ah, Brother Zhu, you are injecting, quickly, put your hand flat, I'll see if there is any leakage!" ”

"It's okay, if you miss it, I'll fight again, I'm so happy to know Brother Huang and know this kind of important weapon of the country!" Zhu Youxiao said loudly.

Huang Xiao smiled, flattened the back of Zhu Youxiao's hand, and looked at it, but there was no missing needle.

Zhu Youxiao sat down again and asked, "Can this be made?" I mean a real steam engine. ”

Huang Xiao shook his head and nodded again.

This made Zhu Youxiao extremely worried, for fear that Huang Xiao would say no.

Fortunately, Huang Xiao nodded again and said, "Yes!" If it's just a prototype, I can make it, but if it is to be mass-produced, it is not so easy. ”

Zhu Youxiao laughed and said, "Okay! That's great! The little brother is looking forward to Brother Huang's prototype! But why is mass production difficult? ”

Huang Xiaodao, "There are great difficulties in this, Brother Zhu, you must know that the raw materials and processes involved must be developed in the name of the country."

For example, this steel, is not the general steel, it has requirements for corrosion resistance, rust resistance, in short, relying on personal ingenuity alone must not be good, I will be the pride of tomorrow hundreds of thousands, if you can gather these talented people, and then gather the strength of the country, it will definitely be able to mass production! ”

Zhu Youxiao nodded, thought deeply, and said, "It's still Brother Huang's foresight, and Zhu takes it for granted." ”

Huang Xiao sighed, "Brother Zhu, don't be presumptuous, alas! Brother Zhu, how do you say you can let the emperor know and agree? Please also ask Brother Zhu to teach me. ”

Zhu Youxiao was stunned, and almost shouted: I am the emperor!

But after thinking about it, if Huang Xiao knew that he was the emperor, would he still talk so freely? Can you still call yourself a brother?

"This is easy to say, it is not a secret, Zhu is also a member of the royal family, although it is a branch line, but he can also ask to see His Majesty, when I have the opportunity, I will definitely transfer Brother Huang's patriotic heart to Your Majesty!" Zhu Youxiao patted his chest.

Huang Xiao smiled: "That's really good! That's it, Brother Zhu! ”
