Nanjing, which is in the dog world, is so hot that people collapse.

At this time, the huge gap between ancient and modern times can be seen.

There is no air conditioning, no electric fan, and no cool modern clothing such as vests and pants, and the summer heat every year is a kind of torture for Zhu Yunwen.

Fortunately, he is the emperor, hundreds of people in the imperial front division are waiting, and dozens of ice guards in a Qianqing palace are replenishing the ice cubes in the cellar all the time, which makes the Qianqing Palace once as cool as early spring.

"Go to Tanglin."

North Korea's military situation has not been sent back, Zhu Yunwen's heart can't calm down, during this time, the number of times he goes to Tanglin has become more and more frequent, one is to escape the summer, and the other is to find that these students in Tanglin gradually have novel ideas every day, and their hearts will be extremely happy.

Sneaked out of the harem, took three hundred guards of the new army, and went out of the Taiping Gate, but no one noticed.

When Zhu Yunwen arrived, this group of students were busy exchanging their latest ideas, and most of them were accustomed to Zhu Yunwen's arrival.

It is also because of the number of times he has come, the Imperial Front Division also built a temporary small palace for Zhu Yunwen here to be used as a walk, surrounded by trees, but there is also a little effect of escaping the heat, Zhu Yunwen will stay here if he has nothing to do, if any student has any strange ideas, they also like to come to Zhu Yunwen to discuss together.

The person who came to Zhu Yunwen the most times was the man named Mo Cheng, a student who was committed to improving the social status of the craftsman.

Zhu Yunwen said at the beginning that before the truth is practiced, we can all question the correctness of the truth, this sentence made Mo Cheng completely let go of himself, and the commonplace things he often encountered in life became an excuse for him to come to Zhu Yunwen.

And this time, he's here again.

"Student Mo Cheng, long live my emperor."

Mo Cheng carried a kettle in his hand, put the latter on the ground, and then knocked his head in a proper manner

Zhu Yunwen looked at him and became curious, "What are you doing, are you planning to invite me to tea today?" ”

The kettle was still steaming, apparently freshly boiling.

Zhu Yunwen rarely put up a stand in front of them, the purpose is to prevent them from being restrained, so that they can speak their minds boldly, so that a bold person like Ji Gang has no excuse to discuss problems and run Zhu Yunwen's good tea.

Mo Cheng explained, "Actually, the students also brought stoves, but they were left outside the hall and not allowed to be brought in. ”

Zhu Yunwen couldn't figure out what Mo Cheng wanted to do, so he waved his hand, and Shuangxi on the side hurriedly sent someone to bring in the small stove that Mo Cheng was carrying.

The fire is still blazing, and it should be just charcoal.

"Are you going to boil water for my show?"

Zhu Yunwen already had a bold idea in his heart, but he still restrained his excitement and asked lightly.

Mo Cheng put the kettle on the stove.

"Your Majesty, don't be impatient."

The water in the pot was originally boiling, and when it was put on, it didn't take much effort to boil, and the lid of the top of the pot was tinkling, and a large amount of water vapor came out.

"Has Your Majesty made any discoveries?"

Mo Cheng arched his hand, his face full of pride, as if he had discovered something terrible.

Zhu Yunwen clenched his fists for a moment!

"Really? It's just that the water is boiling, what's so strange? ”

Mo Cheng was happy, as if he had discovered a treasure from such an inconspicuous little thing, and talked eloquently.

"Your Majesty said earlier that we should question the reasonableness of anything that is taken for granted before it is put into practice, and what is the reason why the lid of the kettle will be pushed when the water is boiled?"

Mo Cheng took the lid of the kettle, and suddenly a large amount of water vapor rushed out of the kettle.

"Here's why!"

Mo Cheng pointed to the rising water vapor, "Boiling water will produce a large amount of water vapor, and these water vapors have a certain driving force in the sealed space, and it is they who push the lid of the pot!" ”

Zhu Yunwen was moved.

He had a hunch that if this Mo Cheng in front of him walked down according to this idea, maybe he, Zhu Yunwen, could see the appearance of the steam engine!

You know, bellows and water drains were born on the land of China for 2,000 years, and after years of evolution and improvement, they are similar to the cranks, connecting rods, flywheels and other devices needed in steam engines to convert circular motion into linear motion, but no one has thought of using these technologies to become one with steam.

In a word, it is technically mature, and what is missing is a flash of inspiration!

"Water vapor turns out to have power."

Mo Cheng closed the lid again, "Moreover, the student has more than just one discovery. ”

As he spoke, Mo Cheng picked up the lid of the pot again and hung it on the palm of his hand, and water droplets fell from the inner wall of the lid from time to time, dripping in Mo Cheng's palm.

"These water vapors, attached to the inner wall of the lid, condensed with each other, and become water droplets."

Mo Cheng's face turned red with excitement, "Your Majesty, that day's classmate Chen Chong once said that the theory of ghosts and gods is nothing, if the rotation of the sun and the moon, thunder, rain and dew are not immortal Bufa, then this pot lid is the most powerful evidence!"

In the past few months, the students have taken a basin of water, put it in the house every night and put it on the cover, and every morning they will bring it out under the scorching sun. ”

Mo Cheng pointed to the boiling kettle.

"The students guessed that it must be the basin of water that turns into water vapor and soars into the sky under the sun's exposure like this boiling hot water, and the students' basin of water is very small, but how wide the lakes and rivers in the world are, and the East China Sea is boundless, how much water vapor will be produced by such exposure, and these water vapors are condensed together, and the origin of the downpour will not be explained?"

Zhu Yunwen smiled in his heart.

Although Mo Cheng's words do not echo all the elements of rainwater formation, the core point is grasped, and most importantly, through a small discovery in his life, he has obtained a strong scientific evidence to refute the deep-rooted theological system that has been formed in society over thousands of years.

"But if the dead thing falls to the ground and not rises into the sky, how can the water vapor reach the sky? Besides, the rain in Nanjing may be explained, leaning on the side of the Yangtze River, so the rain in Huguang and the rain in Fujian and Zhejiang are reconciled? Why does the water vapor formed in the East China Sea rain on the head of Fujian and Zhejiang? ”

Zhu Yunwen thought that his question could be asked to Mo Cheng, but who knew that the latter seemed to have been prepared.

"The students deliberately took the cotton wool for this purpose, the cotton wool will fall indoors, because it has no wind, and it is fluttering outdoors, the less cotton wool, the longer it will float in the air, just like we people will not be blown up by the breeze, the lighter the weight, the more unable to resist the wind, the water vapor is more worthless than the cotton wool, and it is likely to be carried by the outdoor wind and go up to the sky."

It's raining, it's not the dragon lord casting spells!

Thunder and rain are not celestial phenomena manipulated by immortals!

What does this discovery mean for the age of supremacy of monarchy?

In ancient times, there was a drought in the world, the emperor often had to fast and repair, and then set up an altar to pray for rain in the sky, if he failed to pray for rain, the emperor would issue an edict against himself, and at the same time grant amnesty to the world and stop the construction project. In this way, it is a sign of sincerity and repentance to the heavenly spirits.

Those who have seen Daming 1566 will remember that just one that does not snow makes people all over the world panic, and even uses it as the fuse of party disputes.

And once it is discovered that the so-called celestial phenomena are natural phenomena and are not controlled by the gods, then, if there are droughts and floods in the future, it will have nothing to do with the emperor!

This shook the foundations of theology.

If the divine power is unstable, the monarchy will also be unstable!

Under the freedom of thought, the first spark of death has been born.

Zhu Yunwen knew at this moment that his greatest contribution to the Ming Dynasty in the future may be to carefully protect this cluster of scientific flames that are still very weak.

"You like engineering?"

Mo Cheng knelt on the ground, "The students are stupid and talented, and the governance of the country and the students are as profound as the words of the heavenly book, but they are very fond of this side, fortunately, the father of the family is open-minded, and he does not dislike the students because of this."

Originally thought that the rest of his life would only be left in the countryside with farm tools as a companion, Sansheng was fortunate to be favored by His Majesty to summon Nanjing, enlighten the students' thoughts, and encourage the students' naivety. ”

Zhu Yunwen stood up and walked back and forth in the hall for a long time.

"How many other people here have the same hobbies and discoveries as you?"

Mo Cheng hurriedly replied, "Only Xing Yu, a fellow villager of the students, is alone. ”

"I'll arrange a place to go."

Zhu Yunwen thought carefully for a long time, "Go to the Ministry of Industry, you two go to the Ministry of Industry, and boldly do everything you want to experiment and do, and I will send someone to order the Ministry of Industry to provide you with all the things you need." ”

"Student, Thank You, Your Majesty."

Mo Cheng kowtowed excitedly.

"Go ahead."

Zhu Yunwen called for double happiness, "Send someone to send them to Nanjing, pick a house for them, and ask your Xichang to send a general flag for me to protect them." They can't afford to make any mistakes, you know? ”

Shuangxi could feel Zhu Yunwen's attention to this Mo Cheng, and his heart suddenly tightened.

"Your Majesty, rest assured, the slave maid must carefully protect these two by the people of the Imperial Front Division and the West Factory, and there will be no mistakes."

Mo Cheng left, but the excitement on Zhu Yunwen's face became more and more obvious, and he couldn't even hold back for a while, and laughed.

"Your Majesty."

Shuangxi looked at Zhu Yunwenle, but he couldn't be happy, "It's been a long time since the slave maid has seen Your Majesty so happy." ”

Isn't that the reason for the rainfall discovered?

This is not a good thing for the imperial power.

Without the gods of heaven, the four words of the monarch's heavenly endowment will not be tenable.

Zhu Yunwen pressed Shuangxi's shoulder and laughed.

"He found steam!"

Zhu Yunwen's own engineering knowledge is too shallow, he is a liberal arts student, and he has been in the career for too many years before crossing, he is a secretary, not a professional counterpart, he spends all day writing speeches, arranging itineraries for leaders and coordinating the cooperation of various units, more than ten years, how can he still remember the knowledge in the textbook.

So even if he knew the original principle of steam and the gravitational force that everyone knows, there was no other person who could teach the ancients, he would not make a flintlock pistol, he would not have an encyclopedia and a golden finger.

That's why he asked these students of Tanglin to boldly emancipate their minds, because the wisdom of the ancients was very powerful, and they were just bound to a framework for thousands of years.

As long as this mental cage is broken from the periphery, they can take off.

Three thousand years ago, in the Spring and Autumn Period, the ideas of the hundred schools of thought contended, that was the period of the fastest scientific progress of the Chinese nation, and today's mainstream siege equipment is still the batch of improvements from 3,000 years ago, isn't this the most powerful evidence?

Today, Mo Cheng does not rely on him Zhu Yunwen, and has discovered the most primitive steam theory by himself, which means that as long as this whimsy is not suppressed, Mo Cheng is not killed, and his discovery is put in a cage, with the primitive industrial system that is now fully mature and hundreds of years ahead of the West, it is fully expected to manufacture a steam engine!

"Isn't it just a kettle propelled by water vapor?"

Double happiness is not clear, a pot lid that has been pushed, and even the strength is not enough to open the pot lid, as for making Zhu Yunwen so excited?

"Push a pot lid today, and you can push a carriage in the future."

Zhu Yunwen painted a flatbread, "Sooner or later, one day, when the technique is proficient and can push a larger weight, I can send my Daming son-in-law to Tiannan and Haibei in one day!" ”

When the army of the Ming Dynasty is no longer limited by the speed of marching and manpower, Mobei is the back garden of the Ming Dynasty!
