"Rainbow Gate: It seems that the piston is directly made of soft copper. 》

"Enthusiastic Citizens: Yes, even if you can't use soft copper, you can use lead pads, there was a lack of electricity at the beginning of the founding of the People's Republic of China, and a book was published with a 35-horsepower steam engine, 28 parts, most of which are cast iron, and the production of the pot camel machine is all made by the local method [Look]. 》

"Empty chop: you don't have to use lead pads and soft copper, there is rubber grass in our country, we can use it to make gum, and then seal the steam engine.

Moreover, it is a perennial herbaceous plant, which likes cold climates, and the gum contained in the roots can make rubber. It is wild in Xinjiang, China, and cultivated in Northeast China, North China, Northwest China and other places. 》

"The Wind of Loulan: Even if the rubber grass can't be beaten, it doesn't matter, the animal skin is also doped. 》

This......

The people of various dynasties were a little surprised when they saw the comments on the canopy!

They did not expect that the sealing of the steam engine could be solved in so many ways.

Thinking about their previous solutions, they were all stupidly crying by themselves!

Now that they've got these methods on the canopy, they're on the move.

In their time, no matter what kind of copper, it was a very valuable thing, and they and the common people would certainly not be able to afford it.

Although the canopy said that this plant is available in many provinces, they have not seen this plant, nor do they know what it looks like, and it takes too much time for them to find such a plant, and they do not have the ability to find it.

As for the use of lead pads, although they also had this kind of thing in their time, it was not common for them and the people.

As for the animal skins, they saw them all the time, and they had them all.

So many people began to experiment, wanting to see how well the animal's fur was sealed.

They were pleasantly surprised by the results, as animal fur has its own advantages over soft copper and lead pads.

Not only is it easier to process, but it also seals the steam engine more tightly.

It's just that it also has its drawbacks, if the steam engine is used for a long time, the animal's fur is easy to fester, so that the originally tightly sealed boiler has all kinds of air leaks.

However, they are just ordinary people, and although it is more troublesome to use animal skins, its shortcomings are completely bearable compared to the precious soft copper and the hard-to-find lead pads!

Qin Dynasty.

After the Mo family children saw the comments on the canopy, they began to make soft copper and lead pads based on the information on the canopy and brought animal fur, they wanted to test which of these things had a better effect?

As for the rubber grass mentioned on the canopy, they didn't bother to find it.

It was too much trouble for them to find the rubber grass, and even if the rubber grass was in front of them, it was impossible for them to recognize it.

What's more, there is no picture of rubber grass on the canopy, just a brief introduction to its function and where it is.

Although it seems that you can find it based on information, you must know that these places are very large, how can you find them simply, it is like looking for a needle in a haystack.

In that case, they might as well start by tackling lead pads and soft copper and animal fur to see how effective these methods are.

Soft copper is very easy to overcome, and copper products in their era have reached their peak, and soft copper is not a technical problem in this era.

As for the lead pads, it is also very easy, after all, they are the children of the Mo family, the representatives of the most advanced technology in a country, how can they be stumped by this little question?

And as the most dazzling existence of the imperial court now, how could they lack these things!

As for the animal fur, it was any animal fur they needed, as long as they said hello, someone would bring it.

So they began to experiment slowly based on these three materials.

They found that the steam engine was much better than before, and there were no leaks after a short period of operation.

Steam engines with lead pads and soft copper seals do not have these problems and can run for a long time.

It's just that the children of the Mo family were not satisfied with this, and they wrote to Qin Shi Huang again, asking him to send someone to find the rubber grass.

After Qin Shi Huang saw the music of the Mo family's disciples, he was slightly stunned.

For the latest steam engine developed by the children of the Mo family, they are actually very satisfied.

Although after a long period of operation, the steam engine will also have various problems, the most serious is still the air leakage, compared to the steam engine at the beginning, the steam engine at this time can be used completely.

And he began to plan to build a train on the canopy next to Qin Zhidao, wanting to test whether the children of the Mo family could make a steam train.

After the children of the Mo family received the will, they were very excited.

They also didn't want the steam engine they had built with great difficulty to end up lying in that warehouse.

Now the steam train that Qin Shi Huang wants to build is also the time when this steam engine shines!

Han dynasty.

After Emperor Liu Che of the Han Dynasty saw the comments on the canopy, he gave orders to the craftsmen to make new steam engines based on the information on the canopy.

And the craftsmen did not disappoint him, and soon made a new steam engine.

The steam engine, which used to be sealed with various substances, is now unified into lead-electric or soft copper.

Their sophisticated craftsmanship has always been that leak is very small, even very rare?

For this result, Emperor Wu of the Han Dynasty Liu Che was very happy.

Originally, he didn't have any practice in making steam engines, but he didn't expect that a few simple comments on the canopy would solve the difficulty that Dahan couldn't make steam engines.

This once again made him see the horror of the future generations, and also understood why the market is so prosperous!

After the steam engine was manufactured, Emperor Liu Che of the Han Dynasty, who was supposed to run aground, began to build the railway from Chang'an to Xianyang again.

After countless merchants got the information, they also began to act.

They can't interfere in such a project, but after that, they can at least drink some soup.

And the railway from Chang'an to Xianyang, the rails on it are very valuable, even if they drink soup, they can drink rich flowing oil.

What's more, His Majesty's ambitions are not only like this, they believe that as long as they follow His Majesty, they will be able to get rich sooner or later.

Not only those businessmen benefited, but also the people from Chang'an City to Xianyang City.

They were recruited and began to build a unified railway between the two places, and some people were even invited by those merchants to work, so that the poor life has changed a little bit.

They are grateful to the canopy from the bottom of their hearts, and they are grateful for the changes that the canopy has brought to the Han!
