I make a popular science video and all the emperors learn from it!

Hand-operated steam engine and told where the rubber tree is!

In the past, various dynasties were worried that steam locomotives could only be seen but not manufactured.

Now they have hope!

Qin Dynasty.

Ying Zheng unconsciously repeated the introduction on the light screen

"The principle of steam engine...boil water?!"

He remembered that when boiling water, he had indeed seen the lid being pushed up.

But this phenomenon is very common.

Many people, including him, never paid attention to it.

Only now did he realize that it was water vapor that was causing trouble.

Want to understand After that, Ying Zheng was even more shocked.

The steam generated by boiling water could actually move an extremely large steam locomotive!

This time, he didn’t need to give orders.

Everyone in the Mo family present had already started working.

They were going to follow the steps in the video to make the steam engine. come out!

"A glass tube with an inner diameter of 6cm and a length of 12cm."

When they saw the first part, they were dumbfounded.

Glass? They had never seen it in Daqin.

Ying Zheng heard the sound, summoned someone, and ordered someone to pass over the glass from which he drank water.

"It turns out that pure colored glaze is glass!"Fan Xiliang, the leader of the Mo family, was excited.

But glass is neither metal nor wood.

If you are not careful, it will break completely.

Fan Xiliang shook his head and gave up on reshaping the glass, but planned to use bronze instead.

As for the interior As for the diameter and length, just control it at 2. For other accessories, you can find substitutes, so just use them.

Ying Zheng, who was observing from the side, was not idle either.

He called Li Si and asked:"Can the world map be drawn? complete?"

"When I got back to Your Majesty, I had already ordered someone to draw several copies."Li Si nodded.

"good!"Ying Zheng has not forgotten the Americas that he has always been thinking about. After allowing Qin to recuperate for a while, he can send people there to explore.

Compared to exploring the Americas, there is a more urgent matter in front of him.

Ying Zheng then told:

"Find a way to get the sap from the rubber tree as soon as possible, as well as the saplings and seeds of the rubber tree, and then try to plant it in Daqin"

"..."

Li Si wrote down the decree one by one.

Han Dynasty.

Huo Qubing and other generals looked delighted.

When fighting in the field, nothing beats a reliable map!

If you can't figure out the direction during the war and keep going in circles, no matter how much food and grass you have, you won't be able to withstand the consumption, and it will seriously affect morale.

How could Liu Che fail to see the value of the world map.

He immediately ordered people to start drawing according to detailed proportions.

If given the opportunity, which emperor wouldn't want to expand his territory!

Liu Che took a deep breath. Making the steam engine was the most important thing right now.

He immediately ordered the craftsmen to start building it.

At the same time, put the search for rubber trees on the agenda.

Tang Dynasty.

Li Shimin was a little surprised. He murmured:"I seem to have heard of rubber trees somewhere."

According to the description of the light screen.

He heard about trees similar to rubber trees from the envoys of the vassal state.

But he didn't care at the time

"That's all, it doesn't matter now."Li Shimin didn't think about it, and ordered someone to go directly to the rubber tree with a map.

After doing this, he issued an imperial edict across the country. He summoned the country's skilled craftsmen and farmers to build steam engines for the Tang Dynasty!

Ming Dynasty.

Zhu Di squatted down and pinched the tire of the bicycle presented by the light curtain.

"It turns out this thing is rubber."(To read Baoshuang novels, go to Feilu Novel Network!)

A question that troubled him was answered.

In just a moment, he thought of the huge value of rubber!

If the tires of the carriage were replaced with rubber, not only would it run more smoothly, but And it is not easy to slip.

Compared with wooden wheels, rubber has great advantages!

This does not include other uses of rubber.

Zhu Di looked at the distribution of rubber trees on the map and immediately called Zheng He

"Zheng He, I have something important that I need you to do."

"This time is not to promote the national prestige of the Ming Dynasty, nor to find the missing Zhu Yunwen, but to bring the rubber tree saplings back alive!"

"In addition, collect more sap from rubber trees"

"It’s best to bring local people who know about rubber trees back to Daming"

"Yes, Your Majesty."Zheng He immediately accepted the order.

After Zheng He left,

Zhu Di began to order people to try to build a steam engine.

Regardless of whether it can move or not, it is better to make the model first.

【Popular science continues】

【Steam locomotives were introduced to China during the Qing Dynasty】

【But the journey is not difficult!】

【......】

The ancients looked at the light curtain and started communicating

"How difficult was the process of being introduced to China? What kind of hardship method?"

"Brother, it’s normal for foreigners not to want to sell such a good thing."

"Well, that makes sense. Maybe foreigners priced it too high, and the Qing government had to cut off the price to be able to afford it."

"No, no! Have we forgotten what we did before the Qing Dynasty?"

"My day! Brother, when I mentioned this, I thought of Emperor Qianlong. He didn’t even bother to read good things."

"Oops, I'm convinced too. Why did I forget that this was the Qing Dynasty? They were closing the country to the outside world."

"After finishing the game, he might have been beaten to the pulp by foreign guns again, and was forced to buy a steam locomotive at a sky-high price."

"......"

After the ancient exchanges, the collective fell into sluggishness.

When was it bad to introduce it? It was the Qing Dynasty[]
