"What the hell are they talking about?!"

In the secret room, Zhu Gaochi saw that his father had come to the verge of a violent state.

So he hurriedly made another move, "Panda Hugging the Tree", grabbed his father who was pacing back and forth in front of the wall, and suppressed his emotions.

"Father, don't worry, maybe it's something that doesn't pass on the six ears, you just need to go back and ask the second brother or Zheng He to know."

Zhu Gaochi didn't dare to mention Zhuo Jing, everyone knew that Old Man Zhuo was as stubborn as a donkey, and he refused to surrender to Zhu Di, let alone tell Zhu Di what the lecture was.

But Zhu Gaochi had to admit that this kind of silent silence on the other side of the wall, not to mention that his father was itching, and he wanted to know what Jiang Xinghuo had done, even he himself was indeed very much like a pair of clairvoyants, seeing what Jiang Xinghuo had done.

But at the moment, there is really no way to know.

Of course, if these people in the secret room see Jiang Xinghuo's drawings and comprehend the contents, I am afraid they will change the inherent impression that "Jiang Xinghuo does not understand the temple".

Seeing that his father really had the urge to push the wall in a hurry, Zhu Gaochi, who was distracted for a moment, quickly pulled his father back.

Zhu Gaochi did not doubt that his father, who had just completed the four years of Jingjing, had the ability to tear down a newly repaired wall with his bare hands.

If this is not pushed well, it will be hilarious to bury them all inside.

——————

Jiang Xinghuo looked up at the sky and never spoke.

This method, if he doesn't say it at such a juncture, it will definitely not be able to appease the hearts of the top brass of the Ming Empire, and he will not be able to promote change.

It is equivalent to a "letter of nomination" that must be paid.

Of course, Jiang Xinghuo also has countermeasures against this, but there are some things that really can't be said too clearly.

"Got it."

Zhuo Jing was convinced orally.

Zheng He and Zhu Gaoxu didn't understand, and he didn't plan to talk about it.

Anyway, Jiang Xinghuo just scribbled and painted on the notebook casually, and didn't say anything.

"That's all I have for today's lesson, about what is the manufacturing power of an agricultural country, what is the manufacturing power of an industrial country, the essential difference between the two, how to reverse annexation, etc."

Jiang Xinghuo asked, "Are there any more questions?" No problem, just end the class. ”

"I have a problem."

Zhu Gaoxu, who was no longer entangled in the question just now and had made up his mind to go back and ask Old Man Zhuo what was going on, was not polite to Mr. Jiang at this time, and asked directly.

"I remember the topic of this lesson, which is the gap between agricultural countries and industrial countries, which is beyond the reach of imagination."

"Although I know that during the Southern Song Dynasty and the Yuan Dynasty, the kind of handicraft workshops that arose in Jiangnan did have a great improvement in manufacturing capacity compared with the past, and if a new spinning machine was used, I am afraid it would be even more powerful. Moreover, this new set of things that Mr. Jiang said sounded irrefutable theoretically. ”

"But."

Zhu Gaoxu scratched his beard and said, "I didn't see from it that there is a gap that is beyond imagination." ”

This is almost the meaning of Jiang Xinghuo's title party.

Jiang Xinghuo was stunned, but he had a bad information.

Except for the last time in order to test the attitude of the high-level of the Ming Empire, he revealed [Iron Horse] and [Qianli Transmission] in advance, and after that, Jiang Xinghuo did not say anything about science and technology.

Jiang Xinghuo himself is not a person who likes crazy tech trees.

In Jiang Xinghuo's view, the reason why there is a world of difference between agricultural countries and industrial countries is that the level of manufacturing power between them is very different.

The predecessor of the large machine manufacturing industry of industry was the factory handicraft industry, and the premise of the large-scale emergence of the factory handicraft industry was the separation of agriculture and handicrafts, which could not be completely separated in China because of the insufficient grain production and the support of the imperial court.

And since Jiang Xinghuo pointed out the chemical fertilizer, the only scientific and technological point since the crossing, he also learned from Zheng He that he had found several guano islands from Wanli Shitang, and there must be more guano islands in a larger area.

Well, the seabirds have been pulling for tens of thousands of years, and they can't dig up in a lifetime.

In this case, combined with the last crop rotation and intercropping, the agricultural grain output of the Ming Dynasty has already met the critical point of civilization accumulation to the separation of agriculture and handicrafts.

In fact, the upgrade of real civilization is sometimes not fundamentally different from the data-based progress bar in the game.

When grain production accumulates to a certain point, and with a little support, then the separation of agriculture and handicrafts is simply a matter of course.

It is not even necessary for Zheng He to bring back a three-piece set of sweet potatoes, potatoes, and corn from South America, it is enough to complete this civilization upgrade.

And the information difference between Jiang Xinghuo and Zhu Gaoxu appeared here.

Zhu Gaoxu knew what the manual workshop was like, but he couldn't imagine what the "factory" would look like in the future, full of the roar of machines.

Jiang Xinghuo knew what the "factory" looked like in the era of big machine manufacturing, but he did not describe it to Zhu Gaoxu.

In fact, it is the large-scale large-scale machine manufacturing that means that in the era of industrial countries, it is possible to completely crush agricultural countries in all directions.

And big machine building is not just a replacement for traditional handicrafts.

More importantly, due to the emergence of large machine manufacturing, the supply of raw materials and the way of product sales have changed greatly, there has been an obvious social division of labor, and supporting service industries have begun to appear.

In addition, handicraft workers began to transform into industrial workers, such as fitters, welders, riveters, turners, etc., which required supporting vocational and technical standards, as well as specialized schools.

And this process will inevitably be accompanied by the rise of science and the popularization of comprehensive universities.

Jiang Xinghuo came back to his senses and began to explain to Zhu Gaoxu.

"This point, indeed, I omitted something and did not explain it to you clearly, which is why you have the illusion that you think that the era of industrial countries, although it is understandable, is also 'nothing more than that'."

"In fact, you must know that industry is the further development of handicrafts, and the biggest difference lies in the emergence of large machines."

"What is a big machine? The big machine is by no means a huge spinning machine in your impression, I told you before that the [iron horse] that eats coal is one of the big machines, and it is also the most important one. ”

Seeing that Zhu Gaoxu was still a little ignorant, Jiang Xinghuo sighed in his heart.

I want to depict the era of an industrial country to the people of the era of the agricultural country.

This is similar to the difficulty of getting primitive people to understand the scenes of the feudal era.

To put it simply, it is something that people can't imagine, that goes beyond the boundaries of their imagination, and that they can't see.

After all, the people in Jiang Xinghuo's previous life imagined aliens, and they were all abstracted according to their own appearance.

It's like the ancients imagined the afterlife world and created a whole underground bureaucratic system.

Therefore, Jiang Xinghuo knew that he had to find something that Zhu Gaoxu could understand, be interested in, and exist now as an example.

Otherwise, he still can't figure it out.

Teachers, preachers and those who solve doubts.

It is a teacher's shame to teach students and not understand the problem.

Jiang Xinghuo didn't want to be ashamed of being a teacher, so he easily found examples from the direction that Zhu Gaoxu was most interested in.

As the world's number one fierce general, what is Zhu Gaoxu most interested in?

Of course it's a war!

As long as Zhu Gaoxu understands the gap between industrial countries and agricultural countries from the perspective of "war", he will naturally understand how terrifying the concept of "industrial countries" is!

After sorting out his thoughts, Jiang Xinghuo continued.

"[Iron Horse] can not only be used for mining, water pumping, land transportation, water transportation, and even war!"

"Huh?!"

Hearing this, Zhu Gaoxu's eyes suddenly lit up.

If you say anything else, Zhu Gaoxu will indeed reluctantly try to understand in order to listen to lectures and learn, but this is just an attempt.

But if you talk about war, then Zhu Gaoxu will be energetic!

Not only that, Zhu Di, who was next door, as the Ninth Five-Year Emperor, personally eavesdropped on the cracked ceramics, and he also listened with great interest.

Can the big machines of the era of industrial countries be used in warfare?

Interesting, so interesting!

"Mr. Jiang hurry up and tell me, how is this [Iron Horse] used in war?"

"You can simply understand that the enlarged version of the 'Iron Floating Tu', except that what is wrapped in the iron sheet is no longer a war horse."

"What's that?" Zhu Gaoxu asked curiously.

Jiang Xinghuo said: "A huge box with four wheels like carriages underneath, powered by the [Iron Horse], driving them forward. ”

Zhu Gaoxu was stunned, and asked tentatively: "A chariot that doesn't need a war horse?" ”

"Uh, kind of something similar."

Before Jiang Xinghuo could speak, Zhu Gaoxu couldn't wait to ask, "Mr. Jiang, what is this chariot used as an attack weapon?" ”

"Artillery."

"What?!"

Zhu Gaoxu's leopard eyes widened, full of disbelief.

Mr. Jiang actually told him that such a big and heavy artillery could be carried to a chariot?

You must know that in this era, there are indeed artillery, but they are all cast in copper, or even in stone, and they weigh thousands of catties or even thousands of catties at every turn, which is extremely heavy.

So Zhu Gaoxu couldn't imagine how big the chariot must be and how many horses had the same power as a war horse to pull a cannon of thousands of catties.

Jiang Xinghuo immediately understood Zhu Gaoxu's thinking misunderstanding.

Jiang Xinghuo smiled slightly: "Industrial country, there is another point, that is, with the application of large machines, the forging technology of steel has been significantly improved. It's not hard for you to understand this, think about it, if the Iron Horse can become a huge hammer that no one in the world can match, used to forge steel, what craftsman can compare? ”

Zhu Gaoxu suddenly realized, and Jiang Xinghuo continued: "At the same time, you must also know that artillery can be lightweight and cast with steel!" ”

"Why is there no sound?!"

Hearing this, at the most critical juncture, the amplification wall is broken again.

Zhu Di in the secret room couldn't hold back the excitement in his heart at all.

Reach out and press against the wall, a posture of pushing the wall!
