The Master of Time and Space, Earn three small goals with blood at the beginning

“Science? What is that?” Lan Daoxing was confused.

“Science…” Jiang Hao thought for a moment and said, “Science is a methodology.”

“Methodology?” Lan Daoxing was still confused.

Jiang Haodao: “You know that the universe is infinite, heaven and earth are infinite, the sea of ​​learning has no boundaries, and people are born with boundaries, so it is impossible for people to know all the mysteries of this world.”

This time, Lan Daoxing understood, nodded and said, “Even gods can’t exhaust the mysteries of the world.”

Jiang Haodao: “Science is the pursuit of truth when admitting that human beings do not grasp the absolute truth. To be precise, it is to use the laws of nature and analyze the laws of nature to help humans, gain benefits, and know more.”

“To be more specific, after a pot of water is boiled, what will happen to the lid?”

Lan Daoxing was still confused, but he naturally knew the phenomenon of boiling water, so he said: “The lid will be pushed up by the steam. If it is too tight, the lid will collapse. If it is not tight or loose, the lid will fall off.” They will fall together.”

Jiang Hao smiled and said: “The rising of water vapor is a natural phenomenon. The rising will generate force. This force will make the lid of the pot fall together.”

“Suppose the kettle is made larger, the fire is hotter, and the lid is connected more reasonably, the force of the lid rising and falling will be extremely powerful.”

“The power of the pot lid to rise and fall, combined with the hammer, can forge armor.”

“Using the wheel hub to convert it, you can drive the wheels and make the car move.”

“If it is made very precisely, this kettle can drive vehicles and move them. It can also extract water and pump water up. It can also crush rice. This is much more powerful than human power, and even the power of animals cannot reach it.”

What Jiang Hao was talking about was exactly the principle of the steam engine.

Lan Daoxing is a first-class smart man. Although he has never seen a steam engine, he understands the principle after thinking about it carefully.

“Pindao understands, but is this thing very useful?” Lan Daoxing asked.

Jiang Hao smiled slightly and said: “If we use the railway as a road and drive a steam car, it will only take three days to reach the capital from Jinling.”

The steam engine is the representative of the first industrial revolution.

Significant.

It can not only replace animal power, but also greatly improve productivity.

It can also improve traffic levels.

The emergence of railways and trains is of great significance to the development of society.

After the birth of the train, the empire’s land power will also be strengthened to an epic level.

Take counterinsurgency as an example. In the past, when local rebellions occurred, it would take a month for the army to arrive.

With the railway, the army can arrive in three days, which is of extraordinary significance for strengthening local control.

“Three days?” Lan Dao , can’t afford to build such a road!”

Jiang Hao smiled slightly and said: “There are a lot of iron ores in the world. The quality of Daming iron ore is not high, but there are very good iron ores overseas. As long as productivity can be developed, it will not be difficult to build a railway that runs through the country. .”

Lan Daoxing looked at Jiang Hao blankly. The emperor had changed so much that he couldn’t help but be stunned.

After being stunned for a moment, Lan Daoxing came to his senses and asked, “What is productivity?”

Jiang Haodao: “Which one is stronger or weaker, plowing the land with manpower or plowing with oxen?”

Lan Daoxing said: “Of course it is better to use oxen to plow the land. Oxen plowing is more than ten times faster than people.”

Jiang Haodao: “Which one is stronger or weaker is cutting wheat with an iron sickle or cutting wheat with a stone sickle?”

Lan Daoxing said: “Iron is naturally better than stone.”

Jiang Haodao: “Cows are better than people, and iron is better than stone. With better livestock or tools, we can cultivate more land and produce more food than slash-and-burn farming. This improvement is productivity.”

“In the prosperous period of the Kaiyuan period of the Tang Dynasty, the population was only 60 million. Now our territory of the Ming Dynasty is far inferior to that of the Tang Dynasty, and the population has reached nearly 200 million.”

“Why? This is because the productivity of the Tang Dynasty was not as developed as that of the Ming Dynasty. The Ming Dynasty could produce more grain per acre of land, so it had a smaller territory but a larger population.”

“Science is about understanding the laws of nature to increase productivity, making the country rich and the people strong, and the world long-term peace and order.”

Lan Daoxing finally understood.

“So science is just a matter of craftsmen’s ingenuity?” Lan Daoxing suddenly realized.

“There is an element of craftsman’s ingenuity, but not all of it. The craftsman knows what it is but doesn’t know why it is so. Science must not only know what it is, but also why it is so.” Jiang Haodao, “Craftsman is art, science is Tao, and art does not include Tao. , but Tao contains art.”

Lan Daoxing completely understood: “This is what Patriarch Yang Ming said about studying things to achieve knowledge!”

Jiang Hao smiled and said:

“It is indeed a matter of studying things to gain knowledge.”

Lan Daoxing said: “Your Majesty has the benevolence of the Holy Lord. He wants to increase productivity to benefit the people of the world, and is interested in the science of studying things to achieve knowledge. I am naturally willing to help you. I wonder how I can contribute?”

Jiang Haodao: “Your magic can be used to help me build some machinery. Many skills that craftsmen cannot achieve can be completed directly with magic, right?”

“It can be done, but with magic…” Lan Daoxing resisted.

Spells are noble.

Using magic to do this made Lan Daoxing feel a little inferior.

Jiang Hao saw through Lan Daoxing’s thoughts at a glance and said, “Do you think it is beneath the status of a Taoist to be a craftsman?”

Lan Daoxing said: “This… craftsman family is indeed disrespected.”

The household registration system of the Ming Dynasty was very primitive and stipulated that various professions were hereditary.

For example, if you are a soldier, you have a military household.

Craftsmen have craftsmen’s households.

Initially, this approach was conducive to social recovery and development.

But more than a hundred years later, the guard system that military households relied on has completely collapsed.

Before Hu Zongxian took charge of the southeast, fifty Japanese pirates fought all the way to Jinling City, shaking the south of the Yangtze River.

Although these fifty Japanese pirates were eventually wiped out, it also reflected that the Ming Dynasty’s guard system had actually collapsed.

The guard system was a combination of soldiers and farmers. Soldiers enjoyed the land allocated by the court and were self-sufficient in daily farming. When needed, they transformed into soldiers and fought for the court.

It can be regarded as a variant of the Fubing system.

When Zhu Yuanzhang designed the guard system, he proudly declared: “I raise millions of soldiers without costing the people a grain of rice.”

But when Zhu Yuanzhang was alive, land annexation occurred in the guards. Powerful military officers and local gentry caught these “Qiu Ba” bullies, occupied the land of military households, and forced them to become serfs.

After Zhu Yuanzhang’s death, this situation became more serious. Military households either fled or had no fighting capacity.

The Tumu Fort Incident was a direct precursor to the collapse of the guard system. However, because the Ming Dynasty still had some foundation, loyal ministers such as Yu Shaobao managed to turn the tide and did not perish.

But now more than a hundred years have passed, and the guard system has completely collapsed. Therefore, Japanese pirates are rampant in the southeast, and Anda Khan is harassing the north, and no one can control it.
