The development and progress of human beings is a slow process, among them, the development of technology especially needs the accumulation of time, to the middle and late Ming Dynasty, that is, from the sixteenth century to the seventeenth century, the technological development of the Ming Dynasty and even the whole world has encountered a bottleneck, or reached a peak.

This pinnacle is the pinnacle of the simple application of various forces, that is, the simple application of various forces has reached an extreme.

For example, people felt the buoyancy of the water, so there were wooden boats, and by the seventeenth century, wooden boats could be said to be so large that they could not move no matter how big they were, and they would even fall apart when they were launched.

For example, people felt the wind, so they had sails, and the seventeenth century was also the peak of sail battleships, which were so big that no amount of wind could blow.

How can we move forward after the simple application of various forces has reached the extreme?

This question has been pondered by human beings for more than 100 years, and it was not until the 18th century that they finally found the direction of development, that is, transformation, the transformation of simple forces into stable and continuous power.

The steam engine is no longer a simple application of water power, but converts water energy into air kinetic energy, and then converts air kinetic energy into mechanical energy of steam pistons.

Steam power is naturally not something that can be found by looking, this is no longer a simple power that can be found by seeing with the eyes or perceiving with the body, but a kind of power after transformation, if you don't transform, you will never find it!

Of course, Zhang Bin didn't need to explain the physical and chemical principles in the transformation process, or even the law of conservation of energy, to Wang Zheng in detail, if he wanted to explain it like this, Wang Zheng couldn't understand it no matter how smart he was, because he was only a mechanical expert, not a physicist or chemist.

He only needs to tell Wang Zheng about this transformation method, and in short, how to use this steam power.

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

Isn't this a joke, I drink tea every day, why haven't I seen boiling water, Wang Zheng immediately nodded and said, "I've seen it." ”

Zhang Bin continued to ask: "Think about it, if you seal the lid of the kettle, and then put a cork stopper in the spout, and then boil the water, what will happen to you?" ”

Wang Zheng thought for a moment and guessed, "That wooden plug may be squirted out." ”

Zhang Bin nodded and said: "It's not possible, but for sure, think about it again, if you make such a big kettle and stuff such a big wooden stopper, can it also be sprayed out." ”

The kettle he gestured to was the size of a man, and the wooden cork was the size of a man, and he meant to enlarge it proportionally.

Wang Zheng nodded without hesitation and said, "Sure." ”

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

Next, Zhang Bin began to explain while sketching, using the simplest and most intuitive method to tell Wang Zheng how to make a steam piston, how to send steam to the piston, how to use the crank mechanism to turn the reciprocating piston motion into a rotary motion, and how to use the connecting rod to turn the steam valve into automatic opening and closing, so that the steam piston can keep running automatically and so on.

Wang Zheng listened intently, his eyes slowly revealing a gleam, and when he got to the back, he almost jumped up excitedly.

The steam piston that the governor said was what he was looking for, as long as the machinery has such a power, it can run stably and durably, completely replacing manpower, and it is not a problem at all!

If it weren't for Zhang Bin's words, he would definitely find someone to try to make a steam piston immediately.

Of course, Zhang Bin will not just teach Wang Zheng to make a steam piston, how to use this steam piston to process weapons is the key.

He told Wang Zheng how to make steam pistons, not to tell him that it was as simple as applying steam power, but mainly to let him design various machine tools to process weapons as soon as possible!

Immediately afterwards, Zhang Bin explained while sketching, telling Wang Zheng how to use a large gear with a small gear to speed up the rotation, and how to use a long screw rod to slowly close the distance between the rotating drill bit and the barrel.

There is also how to make the machined 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 completely a mechanical problem, and it is simply falling into Wang Zheng's bowl, and he nodded his head again and again, excited.

Finally, after a general introduction of all the machine tools that may be made at this stage, Zhang Bin put down the brush, stared at Wang Zheng, and asked solemnly: "Liangfu, how long can you make a steam piston and a simple drilling machine?" ”

It's about to begin, great!

Wang Zheng said excitedly: "If you can give me enough craftsmen and enough silver, the steam piston will be made next month, and the simple drilling machine will be made before the year." ”

Zhang Bin also nodded excitedly and said: "Okay, if you want someone, you can go to Chuyang and Chang Gung, ask for money, you come to me directly, when are you going to start doing it?" ”

Wang Zheng wanted to start doing it now, but no one, at the beginning, the steam piston must have to be made by hand, he couldn't cast, and he couldn't process and grind.

So, he said embarrassedly: "Xia Guan wants to find a few blacksmiths, coppersmiths and foundries right away, and start as soon as possible." ”

Zhang Bin laughed and stood up and said, "Okay, I just happened to go to find Chu Yang and Chang Geng, go, come with me." ”

With that, he stood up and pulled Wang Zheng to walk out.

Wang Zheng was about to raise his heels, but suddenly realized that he was on duty at this moment, and the city department was now such a chief official, as soon as he left, what if something happened?

He could only stand there and said embarrassedly: "My lord, although there is not much to do here, Xiaguan can't go away." “

Zhang Bin patted him on the shoulder and smiled: "It's okay, the officials are their own people, anyway, there is nothing big about the city division now, just let him do those chores." Besides, the transfer of you to the city department is only a temporary arrangement, so that you can have some merits, and when the time comes, I will report the Gao Cai corruption case, and you should be promoted by the city company. “

The city boss was highly corrupt and was arrested by the governor, Wang Zheng naturally knew about this, but he didn't expect that Zhang Bin wanted to share this merit with him and continue to mention him!

He has been a high school jinshi for almost six years, but he has been a pusher for two consecutive terms, and he has always been the seventh grade, and he has not moved the slightest, and he has never thought that the governor has just mentioned him from the fifth grade, and he is trying to find a way to continue to raise it, which is simply the grace of recreation!

He couldn't help but be moved: "Lord Governor, you have no way to repay your kindness to the lower officials!" “

Zhang Bin patted him on the shoulder and laughed: "You can make the drilling machine as soon as possible is the greatest reward for me, I can count on the musket and artillery processed by the drilling machine to exterminate the pirates and establish meritorious deeds." ”
