Upon his return to Champa, the Champa merchant Daro immediately met with King Jayaparamisu Ravarman IV. Pen, fun, pavilion www. biquge。 info

He passed on the words of Zhang Guoan's island master, and also gave him a weapon demonstration.

King Jayaparamita Shuravama IV was originally an aspiring young king, and he always wanted to have the same exploits as his grandfather, Jayaparami, Shuravarman II, to drive the Chenla people away and re-establish the Champa state!

However, the current military strength of Champa is not good, and it is harassed by Annam and Chenla in the north and west respectively, not to mention that if you want to reach the level of your grandfather, you will not have the confidence to keep it now.

At this time, this batch of weapons gave him hope.

A military general tried to slash with his own treasure knife and the steel knife he sent, but the sword opened a hole, and the steel knife sent there was no problem at all!

Later, arquebuses and grenades were demonstrated outside the palace, which stunned everyone, there are still such sharp weapons in the world?!

King Jayaparamita Shuravama IV immediately agreed to exchange weapons, especially when he heard that rice could be exchanged there, and even black charcoal buried in the ground could be exchanged!

The king of Champa immediately took the gifts from his private treasury and asked the merchant Daro to take them, hoping that they would soon be able to bring the first batch of weapons.

As for the military trainers, the king didn't think they needed it, the generals in his hands were all people of a hundred battles, and there was no need for the well-known Liuqiu guards to train them.

Zhang Guoan, the owner of the island, listened to the merchant Daro's account and nodded, not all kings will have the spirit to accept new thinking, even some local officials.

Now Shimazu, the daimyo of Japanese Samoa, has tasted the sweetness of hired personnel for a long time, and it turns out that all kinds of labor are required on the island of Liuqiu!

So he organized people to go there, and nothing was produced in Samoa. But there is no shortage of manpower.

It wasn't long before he discovered that he was earning more money by sending mercenaries!

Therefore, he always tried to hire idle samurai------ but he was dismissive of rumored weapons, and still believed that swords and arrows were invincible in the world.

In the eyes of Zhang Guoan, this is a good thing. No matter how much he sells, he will not be able to supply arms for export at all.

Arquebus making is now the easiest process in the Bado region, and as more and more artisans become familiar with the process, they have learned to make it by process.

The hot-rolled steel plate designed by Zhang Guoan Island makes the arquebus more convenient, especially the shearing plate technology while it is hot!

Several vacuum steam engines provided them with a stable driving force and could also drive the steam engine hammer.

On this day, the director of Hu Zhenbei said to Zhang Guoan in the hammer workshop: "If the speed and power of the hammer can be faster and greater, let alone a thousand gun barrels, it is 10,000, and I can also guarantee that it will be completed on time!" ”

At this time. Hu Zhenbei, the factory director, wore narrow-sleeved overalls made of cotton and linen, and the overalls were full of speckled oil stains.

The whole hammer workshop was noisy, and the sound was endless.

Zhang Guoan's owner scratched his head at that time------ vacuum steam engine was originally the oldest kind of driving force, at most a few horsepower output, for this time and space, it could have been used for a few years, but now it is developing too fast, and it will soon reach the bottleneck period of the original power demand.

Zhang Guoan, the owner of the island, had to scratch his head. He is most afraid of machining a line.

Before the crossing, he had really practiced his hands. However, the level of actual operation is too poor, and in the words of Director Hu Zhenbei, he can't even hit the fire sickle!

As soon as his friends returned, he sealed the machine unless he was forced to do so. He will never use it------ he is afraid that his operation will hurt the equipment, and he has always had an idea that except for Wu Dapeng, the other three friends should only come back. It's all hands-on.

When he smokes outside the house at night, he often looks at the starry night sky in a daze, are his friends happy in that world?

Is it time to be happy with money or to be happy with youth?

Maybe different people choose differently, but at least he chooses youth, and he truly feels joy in creation and salvation!

The most important point is that after Jing Jing had a child, he felt that it was this time and space, and it was the Great Song people he saved who saved him!

He is finally going to have children------ he is so motivated to think about building a normal society for his children!

However, his lathe skills were too poor.

Quietly and gently: "Guoan, you are an ordinary person, not a god or a saint, let alone a superman. If you don't know machine tool technology, you still have to let the craftsmen of the Great Song Dynasty worry about it.

Maybe they like to worry about something like that. ”

And so it can be.

Zhang Guoan, the owner of the island, had to come up with the drawings of the atmospheric steam engine, which was of course the simplest and easiest to process.

This is the Newcomen atmospheric steam engine, and it has been improved at the same time.

He separated the cylinder wall from the condenser, used a balance lever and tie rod mechanism to drive it, and installed an air pump to remove condensate and air from the condenser.

Finally, a sandwich is added to the outer wall of the cylinder, which can be heated with steam at the same time to reduce condensation losses.

In this way, a truly practical atmospheric steam engine was designed.

The current craftsmen of the Great Song Dynasty are not interested in the vacuum steam engine, but they think that the place where there is black smoke floating on the high chimney, roaring all around, and the air is full of the smell of soot is a good place, and the vacuum steam engine that has been flashing in the middle of the night is the most beautiful scene here.

None of those craftsmen did not understand the principle of the machine's work, and praised Zhang Guoan's master, which was like driving ghosts and gods to do work.

The owner of Zhang Guoan Island was not unafraid to pay attention to their admiration, and hurriedly built his own villa in the upper reaches of the Badao River, so that he could only stay away from the pollution here for the sake of his children.

There is no way, the primary stage can only develop this level.

Zhang Guoan, the owner of the island, handed over the drawings to the director of Hu Zhenbei and said: "Let's build a model first, this is three times more expensive than a vacuum steam engine, and three times more dangerous!" ”

Vacuum steam engines have limited efficiency, but they are safer because they have a lower pressure and the machine shrinks inward rather than exploding outward in the event of material damage.

The use of high-temperature and high-pressure steam brought a huge increase in the efficiency of the steam engine, but this steam engine was much more dangerous than the vacuum steam engine, and the explosion of the boiler and machine caused many major accidents.

Of course, the temperature and pressure they will not be able to reach much at first, but the danger remains.

Zhang Guoan, the owner of the island, naturally also designed a safety valve, to prevent problems before they happen.

He explained the technical essentials and the effect to be achieved to the director of Hu Zhenbei little by little, and then asked them to make a model.

Quiet was right, they were very interested in this machine, which was three times better than the original, and they quickly figured out the principle, but it was not so easy to make it.

However, the order placed by the Champa state still had to be completed, and the so-called atmospheric steam engine model could only be left to worry about in his spare time. (To be continued.) )
