The development and progress of human development is a slow process, among which the development of technology especially takes time to accumulate, and by the mid-to-late Ming Dynasty, that is, from the 16th century to the 17th century, the technological development of Daming and even the whole world has encountered a bottleneck, or reached a peak.

This peak is the peak of a variety of simple applications, that is to say, the simple application of various forces has reached an extreme.

For example, people feel the buoyancy of water, so with a wooden boat, in the 17th century, the wooden boat can be said to be huge to the extreme, no matter how big it can not move, and even if it is launched will be scattered.

For example, people feel the wind, so with the sail, and the 17th century is also the peak period of the windsurfing battleship, the sail battleship is also large to the extreme, and the wind can not blow.

How can the simple application of various forces develop after reaching the extreme?

This problem, human beings have been thinking about for more than a hundred years, until the eighteenth century, finally found the direction of development, that is, transformation, the simple force, into a stable and sustained driving force.

The steam engine is no longer a simple application of water power, but the conversion of water energy into air kinetic energy, and then from the air kinetic energy into the mechanical energy of the steam piston, which is the result of a transformation, so Wang Song said that it cannot be found.

Steam power is naturally not to be found by looking, this is no longer a simple power that can be found with the eyes, or with the body to perceive, but a kind of power after conversion, do not transform, you will never find!

Of course, Zhang Bin does not need to explain the physical and chemical principles in the transformation process, or even the law of energy conservation to Wang Song, he wants to explain this, Wang Song is not understood, because he is just a mechanical expert, not a physicist and chemist.

He only needs to tell Wang Song this conversion method, in short, how to use this steam power.

He asked in the simplest and most intuitive way: "Lian Fu, have you ever seen boiling water?"

This is no joke, tea every day, how can I not see boiled water, Wang Lin immediately nodded: "I have seen."

Zhang Bin continued: "Think about what would happen if you closed the lid of the kettle and then stuffed a cork with the pot mouth and then boiled the water."

Wang Xun thought about it and guessed, "That wooden stopper may be sprayed out."

Zhang Bin nodded, "It's not possible, but sure, you think again, if you make such a big kettle, plug a big wooden plug, is not the same can be sprayed out."

He was a puffin-sized kettle larger than a paddle, and the wood-mounted feet were so large that he meant to be scaled up.

Wang Song nodded without hesitation: "Surely it can be."

Zhang Bin continued to guide: "Well, this proves that after this water boils, the steam force that comes out is very large, and the bigger the pot, the more water, the greater the force, after this you can slowly try, then I will tell you how to use this steam power."

Next, Zhang Bin began to draw sketches while explaining, with the simplest, most intuitive method, tell Wang, how to do steam piston, how to send steam to the piston inside, how to use the crank mechanism to turn the back and forth of the piston movement into a rotating motion, and how to use the connecting rod to turn the steam valve into automatic opening and closing, so that the steam piston to maintain automatic operation and so on.

Wang Xun listened attentively, his eyes slowly showed light, and to the back, he almost jumped up excitedly.

The governor said that this steam piston is what he is looking for, as long as the machine has such a power, it can be stable and lasting operation, completely replacing manpower, is not a problem at all!

If it hadn’t been for Zhang Bin’s words, he would have gone right away to try out steam piston.

Zhang Bin certainly will not teach Wang Xun to make a steam piston, how to use this steam piston to process weapons is the key.

He told Wang how to do steam piston, but not to tell him the application of steam power so simple, mainly in order to let him design a variety of machine tools to process weapons as soon as possible!

Then, Zhang Bin also sketched the explanation, telling Wang Song, how to use large gears with small gears to speed up, and how to use the filament rod to slowly close the distance between the rotating drill and the barrel.

There is also how to make the processed parts rotate, and then use a fixed tool to process the parts, and how to use a fast rotating tool to cut the parts, and so on.

This is a purely mechanical problem, almost fell into the king's bowl, he heard the nod, excited.

Finally, after all the possible machine tools at this stage were roughly introduced, Zhang Bin put down his brush, stared at Wang Xun, and solemnly asked: "Lian Fu, steam piston and simple drilling bed, how long do you have to make it?"

It’s about to start, great!

Wang Song excitedly said, "If you can give me enough craftsmen and enough silver, the steam piston can be made next month, and it can be made before a simple drilling bed."

Zhang Bin also nodded excitedly: "Well, people, you can go to the first sun and Changgong, ask for money, you come directly to me, when are you ready to start doing it?"

Wang Song wanted to start now, but no one, at the beginning, the steam piston must only be made by hand, he will not cast, nor will he process grinding.

So he said, "The officer wants to go to a few blacksmiths, coppersmiths and foundries at once, and start as soon as possible."

Zhang Bin smiled and stood up, "Well, I just want to go to the first sun and Changgong, go, go with me."

Then he stood up and took the king’s song and went out.

Wang Song was about to lift his feet, but suddenly realized that he was currently working, and the city department was now such a master, and he left, what if something happened?

He could only stand there and say, embarrassed, “Sir, there is not much going on here, but you can’t walk away.”"

Zhang Bin patted his shoulder and smiled: "It's okay, the eye is your own person, anyway, the city is not a big deal now, those chores let him do it on the line."In addition, it is only a temporary arrangement to transfer you to the city, in order to allow you to get some achievements, when the time comes, I will report the high-profile corruption case, and your city's import department should also be moved."

The city raised the high corruption and was arrested by the governor, Wang Xun naturally knew this thing, but he did not expect that Zhang Bin wanted to give him this achievement, and he continued to rise!

He was a high school sergeant for nearly six years, but he was a two-time officer, has been a good seven, did not move at all, did not think, the governor has just mentioned him from the five, which is to find a way to continue to rise, this is simply the grace of re-engineering ah!

He couldn't help but say, "Lord, you have this kindness to the lower officer, the lower official does not report it!""

Zhang Bin patted him on the shoulder and laughed, "You can make the drilling as soon as possible is the greatest reward for me, and I can count on the musket gun gun that is processed from the drill to destroy the pirates and build meritorious deeds."
