It is said that without considering the cost and output, even if it is made by hand, it is possible to stack a certain piece of machinery to a very high accuracy.

And the windmill and machine well combination in Zhangjiazhuang is a clear proof of this kind of product!

With the blessing of the craftsmen of the National Treasure level of the Ordnance Inspectorate, the main components of this machine are wrought iron, and the precision parts are made of bronze, and only in the base, shell and other inconsequential positions are used in the wood "money-burning machine".

When the "money burning machine" was officially assembled, and Zhang Qian personally removed the damping of the stuck windmill fan blades, its rhythmic roar and powerful water absorption ability made the people present even more dizzy!

Under the blowing of the northwest wind, the fan blades of the windmill rotate slowly. The gear quickly converts the kinetic energy into the wind, accelerates and transmits it first-stage, and finally lifts the piston of the shaft repeatedly and presses down through the lifting transmission rod. The cowhide pads around the piston quickly pumped the bucket into a semi-vacuum.

Driven by air pressure, the turbid canal water flows down the sealed bamboo pipe into the bucket above the embankment, and is continuously discharged into a fixed tank, and then merges into a stream, heading straight for the small river in the distance! 、

"It's done!" Because he had already imagined the situation when this "windmill machine well assembly" was officially running more than a hundred times in his mind, Zhang Qian didn't feel any excitement, but just looked at it for about half a minute before making a final judgment.

The efficiency is only equivalent to the hand-cranked machine wells that have been eliminated in rural China in the 21st century, and far inferior to electric water pumps. And the cost, even with Zhang Qian's net worth now, it will feel painful to think about it.

The only advantage is that this thing can be switched between the two bamboo pipes inside and outside the embankment at any time through another handle. In this way, the canal water can be continuously discharged into the small river during flooding, and the river water can be continuously pumped into the canal during the drought.

There is still a lot of room for improvement, for example, bronze gears, if they are manufactured on a large scale, they can be cast in fine iron and then polished. Most of the structural components inside the windmill are replaced by hardwood, which does not affect the efficiency of the windmill. As for the service life of the wood, it can be solved by regular maintenance and replacement. Otherwise, looking at the whole of Gyeonggi, the number of people who are willing to make such a bloody thing will probably not exceed 300......

"Little friend, little friend, this thing is really an artifact, and the artifact is also! It is worth more than 10,000 times gunpowder! Before Zhang Qian could finish thinking about how much else could be done to reduce costs, Bi Gou had already grabbed his arm.

At this moment, the old gentleman's body was trembling, his beard was trembling, and his voice was trembling violently, not giving Zhang Qian a chance to be modest at all, so he continued to shout with red eyes: "If this thing is promoted, the flood and drought in my Datang will definitely be reduced by half!" Tens of millions of people will no longer have to sell their children and be displaced. A well-off family, there is no need to worry about being broken by the victims because of a few extra buckets of food, and ending up with no money and no money! ”

As he spoke, he suddenly let go of Zhang Qian's hand, took two quick steps back, lifted his robe, and was about to kneel down on both knees. "With Zhao, please allow the old man to write this thing in detail, and spread its map, structure, and function to the world. The old man is willing to thank Yongzhao for the grace of life for all the people in the world!

Panicked, Zhang Qian hurriedly rushed over and held his elbow hard, "Don't, don't do this!" Please don't do this, old man. I'll give you permission to write and draw as you like, can't you? This thing is erected on the embankment, when will the younger generation not allow people to imitate it?! ”

"With Zhao Daren and righteousness, please accept Zhang's worship!" This car patronized and supported Bi Gou, but unexpectedly, on the other side, Zhang Ruoxu also bowed his head deeply.

"With Zhao Daren and righteousness, Sun Mou thanked the tenants and servants on his own village for the grace of passing on the art!" Sun Anzu joined in the excitement, never willing to be left behind, followed Zhang Ruoxu's movements, and reached the ground for a long time!

"Three, three seniors, broken, broken!" Zhang Qian held on to this, missed that, and was in a hurry. "Isn't it just a windmill and a well, I told the three of you about it a long time ago? If the three elders like it, I will make each of you an identical set! After you take it back, do you dismantle it, or do you have it installed, but you can also drain it! ”

"With Zhao's hospitality, Zhang was disrespectful, so he smiled!" Zhang Ruoxu immediately put away his long skew, and knocked on the bricks with a smile.

"Sun is ashamed, but he doesn't dare to refuse Zhao's kindness!" Sun Anzu also quickly straightened up and nodded with a smile.

"Hmm-" Zhang Qian let out a muffled snort in his heart, so he fainted on the spot.

Fooled again, fooled again, how many times have I lost under the old fox, and I don't have a long memory!

This time it is not a simple few jars of liquor, but a combination of two sets of "windmill machine wells". The cost of each set, in the 21st century, is more than enough to convert into a Ferrari!

Fortunately, the two old-timers were just joking with him this time, and after knocking on the bricks and nails, they shook their heads with a smile one after another, "Sun Mou looked at this thing, and used a lot of copper and iron, and he didn't dare to let it be used." How to prepare the materials, although Zhao sent someone to send a list, the old man will prepare it for you as soon as possible. ”

"The old man is troublesome, how much money should be spent, just send someone to the old man's house to get it. I just hope that Yongzhao will build the windmill as soon as possible, and also add a scenery to the old man's Zhuangzi! ”

"I know that Uncle Zhang and Senior Sun, you two, won't pit me endlessly!" Zhang Qian secretly breathed a sigh of relief and muttered quietly in his stomach. Immediately, he quickly turned his gaze to Bi Gou, who had been holding his elbow by himself, "Senior, your set, junior is for nothing!" If you don't receive a penny, it can be regarded as a little respect for you by the younger generation. Also, the relevant drawings are in the study of the juniors, and the juniors will copy a copy and send it to your house as soon as possible! ”

"The old man has reached the age of sixties, what's the use of asking for so much money?" Bi Gou tried a few times, but because his strength was far less than Zhang Qian's, he couldn't go on, so he had to give up, "This time, I relied on the old and sold the old, and forced Xiaoyou to take out your master's stunt and make it public, and the old man was already very unhappy." The cost of this windmill and machine well, I don't dare to let Xiaoyou break the cost again. ”

Obviously, he could save a lot of money, but Zhang Qian stubbornly shook his head gently. "Senior, I really want to send it! I've heard of the recent thing that my predecessors did. I asked myself if I couldn't be as brave as my predecessors, but I was willing to give a gift to my seniors to strengthen his daily beauty! ”

He didn't know how and how to use words to pay tribute to Bi Go. Although, although the old gentleman admonished the emperor to stop selling his official beard and dismiss the oblique officials in the world, he directly cut off his shortcut to the sky.

He asked himself that he couldn't be as brave and resolute as Bi Gou in the twenty-first century and his current self together, however, he hoped that in the officialdom of two different eras, there would be more Bi Gou, and a few less Empress Wei and Wei Shuban!

He didn't know how many people in the twenty-first and eighth centuries would have the same idea as they were. However, he clearly knows that the reason why China is China is that for thousands of years, there have always been people like Bi Gou, who have stood up one after another and brought the entire nation back on the right track at a critical moment.

These people may not be famous enough, or their morals may not be perfect enough, but their figures and deeds are destined to shine in the annals of history and illuminate the eyes of future generations.

That day, Bi Gou refused a few more times, and Zhang Qian didn't remember.

On that day, who proposed the banquet to see off Bi Gou, and took it upon himself to bring the guests to Zhang's house, Zhang Qian didn't remember.

He only remembered that when he copied the drawings that day, he did so very carefully.

All he remembered was that he had finally given away a complete set of windmill shaft assemblies (promises), a set of design drawings, and a wagon spirits for nothing.

He still remembered the back of Bi Gou's white hair fluttering when he finished drinking and jumped into the carriage with the drawings. Vaguely, there is the same tragedy as a thousand years ago, on the bank of the Yishui River.

The wind is sluggish and the water is cold.

At that moment, Jing Ke was mindless, and Gao was unhappy.
