Qi Heng nodded and continued: "Water ..... after heating into water vapor"

Speaking of this, Qi Heng didn't know how to describe it to make Shen Wansan easier to understand, and after thinking about it, he said: "The space it occupies in the pot will increase, and you can see the lid of this pot, because the space in the pot cannot accommodate these water vapors and there are ups and downs." ”

At this time, Shen Wansan seemed to be listening to someone tell a story, thinking intently. When he heard Qi Heng explain the reason for the undulation of the pot lid, his face immediately showed an expression of sudden realization.

In ancient times, Shen Wansan, who hadn't even gone to school for a few days, had never thought about these problems.

Qi Heng's words surprised him.

At the same time, Qi Heng continued: "Then what do you think will happen if we open a gap in the completely closed pot? ”

Shen Wansan thought about it and said, "The water vapor inside will come out along this gap. ”

Speaking of this, he seemed to think of something, and said, "It's like a teapot!" ”

Qi Heng smiled and nodded: "Yes, just like a teapot, water vapor will spew out along the mouth of the pot." ”

"But what if we make the mouth of the teapot a little longer? For example, connecting from this room to the next door, or even the next door to the next door, and installing a large water dissolver in each room for heat dissipation. ”

Looking at Shen Wansan's gradually solemn brows, Qi Heng patiently explained: "You can use this water dissolver as a ......"

After thinking about it, Qi Heng suddenly pointed to the pot on the stove and said, "You will treat the water dissolver as a sealed pot." ”

Speaking of this, Qi Heng directly brought the pot down and said to Shen Wansan: "You feel the surroundings of this pot with your hands." ”

Shen Wansan said: "It's hot." ”

Qi Heng continued: "Yes, when the water in this pot reaches the boiling point, the entire sealed pot will be squeezed as more and more water vapor increases, and this squeezing power can push the water in the pot to flow to the pot in the next room, and then to the next room. ”

"Eventually, we connected the pipe, the spout of the teapot, to the pot that was heating up."

"What do you think will happen after this circulation?"

Following Qi Heng's train of thought, Shen Wansan quickly discovered the key point, and his eyes lit up: "What my lord means is that these connected rooms will be hot, just like the stove in this kitchen, so that the whole room will be warm." ”

Hearing Shen Wansan's words, Qi Heng finally breathed a sigh of relief.

It was really difficult to spread this knowledge to the ancient people.

Fortunately, Shen Wansan has a flexible brain, if he changes Han Qin, he doesn't know how much effort it will take.

"Then tell me, what will we gain after such a set?"

Shen Wansan didn't think much about it, so he said while thinking about it: "You can save a lot of stove construction, and you can also save a lot of charcoal for burning stoves, and ...... Once and for all, once and for all, once the winter is over, you only need to stop boiling water, and you can use it at any time in the next year. The point is that in this way, people who can't afford to burn carbon can reduce their expenses through this method, and they won't be able to freeze in winter! ”

As he thought about it and said, Shen Wansan immediately realized the importance and role of this thing, as well as the value behind it!

In the life of the ancient people, winter was definitely the most difficult.

Everything is withering, and the weather is cold.

Every year it is not known how many people will freeze to death.

And how many people shivered in the night.

As a person from a merchant family, Shen Wansan quickly thought of the colder weather in the north.

The further north you go, the more valuable this thing becomes!

The most important thing is that the more rooms connected to such a set, the smaller the consumption!

With so many households, the cost will be lower!

At this time, Shen Wansan finally understood why Qi Heng's identity would tell him these things.

Just when Shen Wansan looked at Qi Heng with shocked eyes, Qi Heng only said, "Figured it out?" ”

Shen Wansan nodded.

"As I just said, is it feasible to mix rich?"

Shen Wansan immediately nodded and said excitedly: "If it is operated properly, it will be easy to get rich." ”

Qi Heng, who heard this, put aside the topic and continued: "Then what do you think is the most important thing about what I just said? ”

Shen Wansan thought about it and said, "Water vapor!" ”

After saying that, he immediately shook his head: "No....."

"Yes....."

"Pressure!!"

"Yes, it's the pressure of the big people!"

"It's the one that drives the flow of hot water!"

Qi Heng looked at the enlightened Shen Wansan, and suddenly felt that the son could be taught.

"You're half right, but let's talk about the pressure first."

"Come, follow me."

With Shen Wansan, Qi Heng came to a bright ground in front of the house that was illuminated by firelight, and then drew a teapot with an infinitely extended spout on the ground.

Then a built-in turning device is drawn in the middle of the spout of the teapot, which is infinitely extended, like a fan.

After drawing this, Qi Heng asked, "What do you think will happen if such a fan appears in the mouth of this teapot that has been extended indefinitely?" ”

Shen Wansan immediately said: "The fan will be pushed by water vapor or water. ”

Qi Heng nodded, extending the hinge connected to the fan on the ground.

"What will happen to this shaft on the outside?"

Shen Wansan: "Turn." ”

Qi Heng continued to nod, and then continued to draw on the ground.

When another fan was connected to that shaft, Qi Heng asked, "What if I say that this fan is surrounded by water?" ”

The moment he heard Qi Heng's words, Shen Wansan's eyes widened at the boss, and his eyes were full of incredulity!

He excitedly pointed to the fan on the ground, and even stammered a little: "Big... My lord... You mean......"

Speaking of this, Shen Wansan swallowed deeply and foamed: "My lord is talking about ......."

"Ship ???!!!"

Obviously, Shen Wansan had already thought of the deep meaning behind this.

Shen Wansan, who was in the south of the Yangtze River, it was difficult not to understand the principle of ships.

In addition to relying on sails, boats on ordinary rivers and lakes are manpower.

Even if it is a sea ship, it is only that the sails are larger, and it is also carried out by the blowing of the monsoon.

But now it's different, if such a device can really perfectly replicate the real thing and install it on the boat, the speed of the ship will be greatly increased.

And, it is possible to sail in any situation.

Especially ocean voyages!

Looking at Shen Wansan, whose facial expression was constantly changing, Qi Heng knew very well that as the richest man in Jiangnan who would become the richest man in Jiangnan by relying on ocean trading in the future, he must be able to think of the subversive changes that this thing would have for maritime navigation.

However, Qi Heng didn't want to just forget it, the reason why he wanted to say this to Shen Wansan today was to surrender this person!

Trapping his body and not leaving Huanggang City is not a skill, and it is useless.

What he wants is for Shen Wansan to follow him sincerely and lower his heart!

Then, Qi Heng asked, "Can this thing be the richest man in Jiangnan?" ”

Shen Wansan said firmly: "Yes! ”

Qi Heng smiled casually, and then drew another circle around the periphery of the fan pattern on the ground.

"What about this?"
