The transmission mode, of course Xiao Han knows, is nothing more than chains, belts, and cranksets.

Forget about the crankset, it's too precise! It is estimated that it will not be able to be made for a while and a half, and the wear and tear is too great, and the current material is definitely not practical!

Belts, it's good stuff! But where does Xiao Han go to find raw materials? Damn the rubber trees are still being climbed by monkeys in the Americas! Every time he thought about it, Xiao Han was extremely depressed.

Why? Why are all the good things there?!

Peppers, potatoes, tomatoes, corn, rubber trees! Damn, you're growing one in Datang! It makes Xiao Han want to eat a sour and hot potato shreds now, and the tomato and egg soup are all delusions!

Okay, let's get down to business, these two things are ruled out, and there is only one chain left.

Sturdy, durable, high gear ratio, the only drawback is that the production is a little troublesome, but whatever, he is the Hou Ye, only responsible for asking questions! As for solving the problem, that's someone else's business!

Xiao Han, who had made up his mind, slowly squatted down in the surprised eyes of the old bird and Master Cao, picked up a stick and drew the components of the chain on the ground.

"Well, this is called a chain, and it needs to be matched with iron gears, and the teeth need to be completely fastened to the holes in the chain! One gear turns, and another gear can be driven! We can even install a few more gears, and if one moves, the others will follow! You see, is this transmission still suitable? ”

After drawing the picture, Xiao Han patted the mud and sand on his hands and stood up. Master Cao and the old bird seemed to be enchanted, almost lying on the ground looking at the picture drawn by Xiao Han, while watching, they also used their fingers to follow the drawing on the ground!

Seeing this, Xiao Han didn't think it was strange at all, this is the person who is engaged in technology! When you see something new that you don't master, everything around you is immediately forgotten, and you only have your own world in front of you!

For the time being, let the two of them study first, Xiao Han walked to the side with his hands behind his back.

There is a gantry crane built of wood, which uses Xiao Han's pulley technology, which can easily lift thousands of pounds of heavy objects, which is extremely practical for construction machinery!

Under the gantry crane, there is a group of people, the big ones are young and the youngest, the big ones are about fifty or sixty years old, and the small ones are only in their early twenties.

Xiao Han was in a good mood, and when he saw these people so restrained, he waved his hand: "You're welcome, everyone, just do whatever you have to do, I'll take a look at it!" ”

These people may have heard Master Cao talk about Xiao Han, and when they saw this Hou Ye talking so well, most of their apprehension disappeared, although they raised their eyes from time to time to peek at Xiao Han, but the work in their hands was not messy at all.

Walking along the way, Xiao Han became more and more pleased the more he looked at it.

Originally, he thought that he was just arranging a few people at random, but he didn't expect that this was really a treasure!

Not to mention anything else, just that old man is a rare talent. Now look at these people, it's only been a few days since they were full? These new tools, new technologies, including cement can be applied to clinker! Where is this Xiao Er's mouth called Huazi, it is clearly a group of extremely powerful craftsmen!

"This little thing, it's worth a beating!" Secretly scolded Xiao Er, Xiao Han blamed all the faults on poor Xiao Er, if it wasn't for the wrong information he gave, he would have come over to take a look, and he wouldn't have found out about this group of treasures until now!

"Master Hou, who are you scolding?"

was scolding, and suddenly a voice next to him sounded coldly, almost startling Xiao Han! Quickly turned around and looked, but it was Master Cao standing aside with a surprised face.

"Who cursed? Master Hou, I am a humble gentleman, how can I scold people! It's because you have a problem with your ears! Hey, what about the old birds? Xiao Han's face was not red, and he defended himself without a heartbeat, and looked back again, but he didn't see the strange old man.

"Your ears are broken! Owe a gentleman, you do it more than you do when you move your mouth! Master Cao clenched his fists, and really wanted to scold, but when the words came to his mouth, he swallowed them alive, Hou Ye was a careful eye, which made him angry and embarrassed, and he really couldn't make it...... Therefore, Master Cao could only scold these words in his heart, and he still pinched his nose on his face and recognized Xiao Han's "gentleman's style".

"I heard it wrong... Elder Yu thinks that you have made that thing extremely feasible, and you have already gone to the steelmaking workshop to build a prototype, Master Hou, you will also go and have a look? ”

"Well, I'm not going, I'm not going, you can do it yourself!" Xiao Han shook his head, he really didn't want to go to the steelmaking workshop, he went once, and he was dizzy, not because of the poisonous gas, but because the heat wave really made Xiao Han unbearable, and he didn't dare to run out casually, for fear of flashing, catching a cold again, a cold is not a trivial matter this year!

Master Cao had long expected that this would be the case, but it was already an unexpected joy to get the chain today, and Xiao Han was going to go on an expedition in a few days, so he didn't do much reluctantly, and he took a few people to the steelmaking workshop.

Returning to the Hou Mansion alone, retiring from the others, Xiao Han sat alone in the study, spread out the paper, and began to write down his plans for the future.

He can't say the length of time for this expedition, let alone predict the good and bad, only by listing all the things first, can he go out with peace of mind.

And Xiao Han also believes it! In the hands of the fiefdom, things will only be done better than you expected!

Perhaps, even Xiao Han didn't expect that he would sit from the afternoon to the evening!

It wasn't until Ziyi knocked on the door and came in to light the lamp that Xiao Han suddenly realized that the sky outside had darkened.

rubbed his eyes, folded the paper in front of him, and looked at the beauty palm lamp, which was also a unique flavor.

"Ziyi, how are you doing here?"

Xiao Han asked with a smile, after getting along for a few days, Xiao Han and Ziyi slowly became acquainted.

But don't think about it, Xiao Han is not an animal that thinks on the lower half of his body. For Ziyi, he just simply appreciated it.

For this reason, Ziyi was a little relieved and a little lost in his heart, and only he could experience the taste.

Hearing Hou Ye ask himself, Ziyi took a step back and made a blessing to Xiao Han, and then said lightly: "Back to Hou Ye, Ziyi is very good here, better than before!" ”

"Well, we're not somewhere else, we can talk about anything. And when you have a break, you don't have to stay at home all the time. Go out and have a look, even if it's to Chang'an, it's fine. What's the problem, let them come to me! ”

Xiao Han said with a smile, although his tone was gentle, he was firm and domineering, which made Ziyi suddenly have an illusion that the Hou Ye in front of him was not a sixteen or seventeen boy, but a middle-aged man who had been weathered for a long time.

"Yes, Master Hou......" Ziyi replied with mixed feelings.

"Okay, you go and tell the kitchen and let him bring my food to my master, where will I eat tonight."
