"Of course I know! Who made this! That's what I wanted to do before!" Xiao Han grabbed Master Cao excitedly and sprayed all the spit on his face!
"This is me..." Chief Cao, who was grabbed by Xiao Han, was about to speak, but stopped at the last second!
He coughed and then said: "Ahem...this is done by my friends, um, friends! They are the same people I wanted to arrange to come in last time..."
"Are you talking about them?"
Xiao Han pointed at the black brothers carrying coal in disbelief, his mouth wide open enough to fit a fist into it!
"That's not true. These people are just latecomers. We can't let others do this. It's too wasteful. They are probably studying waterwheels by the river now."
"What? The waterwheel is also out?! Why didn't you notify me of such a big thing! Let's go! Take me to see it quickly!"
Chief Cao was pushed out by Xiao Han like a dung cart. He was in a state of dumbfounding. Who didn't inform him? It was obvious that he was too lazy to play around every day. Good guy, when things happened, he was blamed again!
But no matter what, who calls me the Marquis or the Lord? Just bear with it!
After leaving the door, he hurriedly took a cart to the lower reaches of the river. Xiao Han saw on the cart that the originally wide river channel had been blocked by an earthen dam at some point, and the gentle river passed here.
As soon as it was blocked by the earthen dam, the water flow immediately became much more rapid! And under the dam, there were three or four waterwheels of various sizes!
"This is what you made in the past few days? So fast?" Xiao Han swallowed hard, and before the cart stopped, he jumped off and quickly ran to the waterwheel.
The river water in early spring still carries a trace of ice, rushing against the tall waterwheel made of logs. The large waterwheel, which is more than two feet high, is turning slowly and slowly. At its edge, there are also tied
There are many bamboo tubes.
With every rotation of the waterwheel, the bamboo tubes immersed in the river were filled. When they reached the highest point, they were dumped out again. Although they were all dumped in the river now, Xiao Han knew that as long as he connected a few
Only bamboo tubes can automatically transport the river water to the dry land! By then, the dry land will be turned into paddy fields!
After looking at this waterwheel, Xiao Han looked greedily at the smaller waterwheel next to it. Perhaps because of the low resistance, it turned much faster than the larger one!
Of course, the size alone would not make Xiao Han lose his composure! What really surprised him was: this waterwheel actually had gears connected to it!
Xiao Han dared to swear to God! He really saw the gears! Although they were still very rough and made of wood, they turned one by one and the teeth were interlocked. What are these if they are not gears?!
Xiao Han was dumbfounded, but Chief Cao bowed slightly and said something to an old man walking by the river.
The old man's hair was completely white, his face was wrinkled, and his back was heavy, but only his eyes were extremely clear. When he looked at Xiao Han, there was a strange light flashing.
"Old Cao, Old Cao...I'm a little dizzy, who did this?" A burst of water vapor came, waking Xiao Han up from his chaotic state. He wiped the moisture from his face, and Xiao Han shouted to Master Cao at the top of his lungs!
He really couldn't believe what he was seeing! In Xiao Han's mind, if someone could complete all of this with design and production in just a few days, then he must not be human!
Chief Cao heard Xiao Han's cry and confessed to the old man. He quickly came to Xiao Han and said to him: "Master Hou, this is one of my...well, uncle, he drafted and completed these designs."
!”
"Where is my uncle? Take me to see..." Xiao Han pulled Master Cao, wanting to know what this person who is not human looks like!
That’s outrageous! Even if Lu Ban was alive, he couldn’t play like this!
Chief Cao smiled and pointed at the old man not far away: "Here, that's who it is!"
Xiao Han looked in the direction pointed by Master Cao and saw the smiling old man.
At first glance, Xiao Han felt that this man was really different! Looking at his face alone, Xiao Han couldn't even tell his age!
With his face full of wrinkles and withered white hair, it’s okay to say he’s sixty or seventy years old, and some people will believe him if he’s seventy or eighty!
But those eyes, no matter how you look at them, look like a child! Could it be that he is a child again, and he is a child again?
"Junior Xiao Han, I have met my father-in-law. Do you dare to ask me his surname?" Xiao Han did not dare to act like a marquis to this strange man, and quickly greeted the old man with the etiquette for his elders.
The old man came over, smiled gently at Xiao Han, and then said: "Haha, I have met Mr. Hou. My real name is Qin. As for my name, I haven't used it for a long time and I have forgotten it. Mr. Hou called me Qin Lao!"
"My surname is Qin?" Xiao Han didn't know that there was such a surname. He was stunned for a moment, then bowed and said: "I don't dare to call myself master in front of the old gentleman. Mr. Qin can just call me Xiao Han! Wan Sheng wants to ask Mr. Qin,
Are all the waterwheels on this river made by you?"
After all, Old Man Hua still taught Xiao Han a little bit. In terms of respect for elders and younger ones, which was most valued by the ancients, Xiao Han was almost perfect at this time. He really lived up to Old Man Hua's "careful teachings".
Seeing Xiao Han being so humble, Mr. Qin also laughed loudly, stroking his long white beard and said: "Yes, you can also say no."
"How do you say this, Qin Lao?" Xiao Han was a little confused, scratching his head and asked the old man.
"Master Hou, let me explain this to you." Chief Cao spoke up at the right time and explained to Xiao Han: "Actually, the waterwheel was not thought up by you, Master Hou, let alone Qin Lao!
It had already appeared in the Han Dynasty, but it was not widely used because of its low durability. Later in the Jin Dynasty, there were already sporadic millstones driven by waterwheels. And now these waterwheels are all based on Qinlao
The remaining drawings were redesigned, otherwise who could build these things in a few days?"
"Oh~" After listening to Chief Cao's explanation, Xiao Han understood. Fortunately, it's not too outrageous! If there is a genius who can design so many things in a few days, Xiao Han really needs to consider what this person can do
Isn't he also a time traveler?
"Oh, by the way! What happened to you when you told me on the way? What problem did you encounter?" Xiao Han looked at the whirring waterwheel and suddenly remembered what Director Cao said before he came.
"Transmission! The problem now is the transmission!" Chief Cao was going crazy. He had been talking about it for a long time on the road, and Xiao Han didn't listen to his feelings at all...
"Transmission? Isn't there a gear? What's wrong with the transmission?" Xiao Han asked strangely, pointing to the gear that was still running.
Master Cao's eyes were almost red, and he said loudly: "There are gears, and the bearings you made are really useful, but the water hammer is too big! And for the convenience of processing, it needs to be placed farther away from the river bank. This distance
The gears can’t be reached at all! If you add too many gears, they’ll break easily, and you’ll be stuck here now!”
"Oh, that's it." Xiao Han nodded and asked, "Then you haven't thought about using other things for transmission?"
"The old man also thought about wrapping two sets of gears with knots, but the cast water hammer is too heavy, and ordinary ropes will break after just a few times. Even ropes made of old rattan wires will not last long, and they will not last long.
It cannot be used with oil like the rotating shaft."
At this time, Mr. Qin opened his mouth and explained the problem simply and clearly, and then looked at Xiao Han quietly. Cao Housheng said that this boy is a genius. Although the extremely exquisite turning axis can prove this,
But Qin Lao still wanted to witness it with his own eyes.
