Three Kingdoms period.

Cao Cao, Liu Bei, and Sun Quan looked at the comments on the canopy, they didn't expect that the original solution to the seal was so simple.

According to their original thoughts, they have always believed that only the rubber mentioned on the canopy can solve the problem of sealing!

However, now the comments on the canopy made them realize that there was more than one way to solve the sealing of the steam engine.

And the use of rubber seals in later generations on the canopy is only more cost-effective in their opinion.

There was no rubber in their time, but there was soft copper, lead pads, and animal skins.

So they experimented with these materials, and found that each of these three materials had advantages and disadvantages, and the lowest cost was the animal skin, followed by the lead pad, and finally the soft copper.

So they sealed the steam engine with these three substances according to their various uses.

One steam engine after another was built by them, and then used in various ways.

And since the advent of the steam engine, Shu, Wei and Soochow, which were already in various competitions, have entered incandescent.

The various technologies on the canopy were used in various aspects one by one, and countless talents began to burst out, and then various technologies were twinned based on the technologies on the canopy.

Sui Dynasty.

Yang Guang saw the comments on the canopy, and he looked at the craftsmen around him again.

He felt that these craftsmen were simply stupid people, or they couldn't fill in the simple method, why didn't they think of it?

He felt that the craftsmen who had been killed deserved it, and that if they could have thought of these methods, they would not have been killed by him.

Then he snorted coldly, and left the workshop outside Luoyang City and returned to the palace in Luoyang City.

Those craftsmen looked at Yang Guang who was leaving, and they were covered in cold sweat.

They were very afraid that this time Yang Guang's arrival would be their talisman.

Thankfully, it didn't happen, and they were able to survive for a while.

After they calmed down, they remembered what had been said in the canopy, and then they went back to action.

They didn't want to die, and now that the canopy had given them away, how could they not copy their homework?

Then the steam engine made of three materials was made, and according to various experiments, he finally determined which material made the steam engine was better.

Subsequently, someone sent these three steam engines into the palace for Yang Guang to inspect for himself.

After Yang Guang received the steam engine in the palace, he was very surprised.

This made him feel even more that those craftsmen must not have worked hard to make a steam engine before, otherwise how could they not have thought of a simple method on the canopy?

Tang dynasty.

Li Shimin read the comments on the canopy, and his heart was simply pleasantly surprised.

Ever since the Sky Curtain broadcast how to make a steam engine, especially after letting him know the specific role of the steam engine, he has always been thinking about this kind of thing.

However, compared to the various things that had been made before, the difficulty of this steam engine was too great.

Even when he gathered the best craftsmen in the country, there were always problems that went unsolved.

In particular, the problem of sealing made the craftsmen bald.

And now these methods mentioned on the canopy made them realize that it was so simple.

So they made a steam engine again, and then experimented with it.

The results of the experiment made them very satisfied, the steam engine made by using the method on the canopy can not only run for a long time, but also can drive all kinds of machines, as stated in the canopy.

Let Datang, which was originally short of labor, begin to slowly no longer lack labor!

Countless lands have been cleared for a variety of crops, and land lacking water sources has been irrigated by steam engine-driven waterwheels.

Song dynasty.

Zhao Zhen read the comments on the canopy, and he secretly breathed a sigh of relief in his heart.

The more he knew about the role of the steam engine in the canopy, the more he hoped that he Da Song would be able to have this kind of machine.

Although he was very confident in the craftsmen of the Great Song Dynasty, he also hoped that the Great Sage would have this kind of machine as soon as possible.

And now the comments on the canopy have pointed them in the direction that a successful steam engine can be made using these materials.

And in addition to the rubber grass, he has other materials in the Great Song Dynasty, and even these materials are not uncommon in his Great Song Dynasty.

Of course, as a national currency, the cost is too high if it is used.

Zhao Zhen is even more optimistic about the lead pad and animal fur, these things are very cheap to use, and they can be used on a large scale in the Great Song Dynasty!

And after the craftsmen of the Great Song Dynasty saw the comments on the canopy, they began to experiment.

For the steam engine on the canopy, they also longed to have it.

If they have it, they can not only get a lot of money, but also improve their skills again!

And the folk businessmen have already fried the steam engine to a sky-high price, if they make it, they can make one can completely return to the cost, and make two can go on a rich life!

Ming dynasty.

Zhu Yuanzhang saw the comments on the canopy, and then looked at the steam engine that had been made, and he asked those craftsmen to experiment with the methods mentioned on the canopy.

After some time, four people came to report the results of the test.

Although the method on the canopy is useful, it is still a bit weak compared to the steam engine he uses rubber!

If you use it for a short time, you can't feel the difference, but after a long time of use, you can feel the difference between rubber sealing and other sealing methods.

This also made Zhu Yuanzhang realize the importance of the New World again, he thought for a while, called the crown prince Zhu Biao and Zhu Di, and began to discuss with them how to occupy the New World.

Da Ming in another time and space, Zheng He looked at the newly made lucky boat, and he was very happy in his heart!

His lucky ship is different from the previous ones, it has a double power, using the monsoon winds of the ocean and the steam engine, so that the area that could be reached in ten days can be reached in just three days!

This made him full of confidence in the next trip to the West, and he was also full of curiosity about the new continent.

He wondered what kind of surprise he would have next time he went to the New World.

Late Ming Dynasty.

Zhu Youzhen looked at the comments on the sky, and he began to plagiarize the homework on the Tianmu again,

After taking notes, he began to find Xu Guangqi and Song Yingxing.

Now that Tianmu has given them an answer, Zhu Youzhen believes that his two generals will definitely be able to give him a satisfactory answer!

At the same time, Zhu Youzhen is also planning to build a railway from the capital to Liaodong, so that it will be more convenient to transport military supplies and soldiers.

After Xu Guangqi and Song Yingxing saw the comments on the canopy, they no longer went to those foreign monks, but gathered those craftsmen to discuss how to use the methods on the canopy to make steam engines.

After many experiments, they finally made a relatively satisfactory steam engine, and finally they told Zhu Youzhen the good news.

After Zhu Youzhen heard the news, he was very satisfied, and began to reward those craftsmen, and then discussed the construction of the railway with Xu Guangqi and Song Yingxing.

Xu Guangqi and Song Yingxing agreed with Zhu You's overhaul and construction of the railway, but what worried them was the state's finances.

After all, the Ming Dynasty at this time is really full of natural and man-made disasters!

After Zhu Youzhen heard it, he fell silent, and then waved his hand to let Xu Guangqi and Song Yingxing go back.

Maybe the success of this period of time made his mentality a little floating, so that he forgot that the current Daming is like cooking oil on fire, and if it is a little worse, the building will collapse!
