I! Jar merchant, Qin Shihuang prescribes the elixir of longevity at the beginning

"Using water?"

"It's a good idea, I didn't think of it before."

"Think of what is the use, you are not a craftsman, and you can't toss it."

"Yes, yes."

"However, this can only be built on the river, and due to the flow of river water and seasonal differences, the magnitude of production will also fluctuate, right?"

"It's good to be able to increase it by forty or fifty times, even if it is affected to reduce production, it is definitely faster than pure handwork."

"Zhao

Xing and Zhu Yuanzhang, you glanced at me."

The defect of this hydroelectric 'spinning machine' soon came to mind.

But.

Take a step back and think.

No matter how much the output is reduced, it is far faster than ordinary artificial spinning, which is nothing.

"No, the point you made makes sense." Li Xiaohan said with a smile, "Indeed, this is only the most basic achievement of the first industrial revolution, so there will be factors affected by the seasons, but they quickly made reforms and invented the 'steam engine'." "

A steam engine is a reciprocating power machine that converts the energy of steam into mechanical work.

It requires a boiler that boils water to produce high-pressure steam, which can use wood, coal, oil or gas or even combustible waste as a heat source.

Steam expansion pushes work to do.

The emergence of the steam engine was the greatest achievement of the first industrial revolution!

"What is this?"

"I won't say much about the specific principle, anyway, you are not professionals and you can't understand it." Li Xiaohan said, "To tell you simply, he can make all walks of life such as textiles, mining, metallurgy, flour grinding, manufacturing and transportation, and even the construction of warships." "The

use of steam engines.

It not only greatly improved labor productivity, but also promoted the development of commerce and transportation, accelerated the process of urbanization, and greatly changed human life.

Let Zhu Yuanzhang and Zhao Xing listen like a dream.

That's right, too.

The fruits of the first industrial revolution.

In the Daming Empire, which had just been established for twelve years, it seemed a little too early.

Even the Western world only entered the first industrial revolution after 380 years, leading by nearly four hundred years, coupled with the lack of professional explanations and guidance, which made Zhu Yuanzhang's brain buzz.

Zhu Yuanzhang muttered, "Are there really so many benefits?

Li Xiaohan swiped his finger, and the terrifying inner qi instantly formed a model of a warship, but it was pure white.

Its mighty form is daunting.

Whether it is a warship of the Han Dynasty, or a warship of the Daming Period.

In front of the warship that Li Xiaohan simulated with internal qi, it was all the role of 'younger brother among brothers', and it was not vulnerable at all, because it was made of pure steel, far from being comparable to wooden warships.

"Have you ever thought that the armor of a warship is made entirely of steel?"

"Steel shipbuilding, that's not realistic, right?"

"That's right, the weight of iron is too great, if you use it to build ships, I am afraid that it will sink to the bottom of the sea in minutes."

"So, have you tried throwing a hollow iron ball into the water?" Li Xiao said lightly, "Will it float or sink."

"This..." "

If Xing guessed correctly, it should float."

Zhao Xing pondered for a moment and said.

When he was a child, he also did similar behavior, and he is still impressed.

Soon.

He understood what the example given by the immortal master meant.

"Immortal Master means that steel warships are like hollow iron balls, even if they sail on large rivers and seas, they will not sink?"

"That's right."

"But how can such a heavy warship be pushed?"

Zhu Yuanzhang quickly threw out another question.

Large wooden boats alone cannot be propelled by wind and manpower alone.

If you can't sail, isn't this just a flower shelf in front of you, completely useless?!

"That's where the steam engine works."

"Through special mechanical theory, let steam generate powerful power to propel the steel warship forward."

"Its speed is even several times that of wooden warships that rely on wind power and manpower!"

"With speed and defensive suppression, if equipped with long-range artillery, it is even more irresistible, crisscrossing the seas!"

".............,"

Li Xiao said lightly.

The ancient Chinese crossbow and arrow "two armies meet, the bow and crossbow compete first", the invention and widespread use of the crossbow, so that the offensive defense and fighting on the battlefield increased sharply a little fiercely.

In ancient times, along with the crossbow, there was also a "long-range" firing weapon called a cannon.

This cannon is a rock thrower.

From the perspective of combat form, it can be fully regarded as the originator of artillery, once known as "the first attack weapon in the army".

Merely.

Since there was no impact of the first industrial revolution.

As a result, although the prototype of the 'cannon' first appeared in Huaxia, it did not develop and expand it.
