Danzhu studied for a day and a night without eating.

It made Yu Yu a little worried.

"Patriarch, we all saw Ah Hong eating soil hungry...."

The old patriarch is much more keen, and the envoys of the Central Plains definitely did not come from afar to eat soil.

It's just that during this time, he has been dragged by Qiao Song and others, nagging about the family's shortcomings, but now he is idle but he doesn't go to the wizard, but wanders around in the Chifang clan, in view of his sensitive identity, the old patriarch not only has to give Qiao Song and a big boost to their face, but also gives Ah Hong, the envoy of the Central Plains, face.

However, it has been many days since the contact was stopped, the rice in the south has been dried, and it seems that the autumn harvest in the north is coming, and the harvest time in the south is dozens of days earlier than in the north, of course, this dozens will not exceed a month and a half, mainly because the climate in the south is warm and the crops grow quickly.

After drying, the tools that Wu made before can come in handy.

Flails, stone mills, and most importantly, treadmills.

"You don't care about his affairs, you also eat soil when people eat soil? Don't learn it, maybe people are tasting something, I guess I also saw that the soil composition is different, you kid, the elf is very, spread rumors here, and learn from Yu Pan?"

Yu Yu smiled: "I just think it's strange that he came here to look at this and look at that." ”

The old patriarch shook his head: "That's the envoy of the Central Plains, when we were in the Central Plains, we didn't see anyone from the imperial court, right?"

The so-called imperial court is the center.

Danzhu naturally kept his promise, and the grains were returned on time, but his "battlefield" was not facing Sanmiao for the time being.

The ox cart obviously interested him more, and in fact, with this thing, the cart he held in his hand was useless, compared to the practicality, maneuverability, and the smoothness of the wheels and turns, the car in his hand was a big step behind.

Danzhu's primitive vehicle, which is between a log car and a real horse-drawn carriage, the kind of wheel without spokes, is called "辁 (quan)"

辁, the fan car under the 庳 (bei) wheel also.

When Danzhu saw the stepping mill, the fire of the craftsman in his eyes burned.

"So many new devices!"

At this time, he suddenly resonated a little with Yu Zai, who had never seen him before.

I see! This is also a man who thinks that equipment is a productivity witch!

In addition, the previous wheels, canals, waterwheels, straight and curved ploughs, as well as those that were popularized by Dayi, some of the water control concepts about Yu Zai all reflect the importance of tools.

Don't say it, I know you! You like woodworking equipment, I also like woodworking equipment, woodworking equipment is the first in the world, we are half-brothers!

Danzhu appeared like a ghost, which scared everyone, of course, Danzhu immediately said, please play this device to yourself.

"That's it... Foot on it, one-two, one-two..... Eh, you ask me what does this slogan mean? I don't know, it's not interesting, it's just counting, Wu's verbal habits, I wrote it down the last time I listened to it, but it sounds quite rhythmic...."

When the rice is withdrawn from the ground, the grain and the ear stalk are mixed together, and after threshing with wind, bulging, bamboo sieve, etc., it is pounded in a stone mortar, and then a few times are bumped and sifted to remove the bran and husk, which is a very tiring process.

But Dan Zhu stepped on this, but he felt very relaxed, his body was dancing up and down, and the huge wooden pestle in front of him was also smashing down into the round pit with his stepping.

The paddy begins to be hulled.

As for the flail, that thing hammer will do, I use nunchucks, knock knock......

Of course, after Danzhu used it, I felt that it was good, but I always felt that something was missing.

His gaze was on the second weight.

Stone mill and grinder! These two things look very similar, but the work is a little different.

So as soon as Danzhu got started, those eyes suddenly began to shine!

Oh, good fellow, there's weight! That's the aesthetics of men!

"No, no, no, it's a cow, it's not a human .....!"

However, a group of fighters could not stop Danzhu's attempt, and Danzhu pushed the millstone, trotted all the way, and spun and flew!

The big grinding disc is creaking, and the grinding disc here is broken!

Click!

"Ah, it's broken. ”

Crowd: "......."

Danzhu took the broken wooden stick and said to everyone: "It's nothing, I have probably figured out the principle of this thing, it's not that I speak badly, the principle of this thing is actually very simple, it's too easy to copy....."

However, having said that, Danju quickly left, saying that he would get them another better one the next day!

Yes, better!

This stone mill just broke a handle ....

"This, Ah Hong, just change this one....."

However, when Yu Yu spoke, Dan Zhu had already run away, only in the sunset, leaving everyone with a youthful back running with all his might.

"It's nice to be young...."

The old patriarch said with emotion, and the old people in the clan also nodded.

The messenger of the Central Plains is really spiritual.

However, Danzhu's mouth was heard by Yu Zai, and the next day, Danzhu didn't sleep for most of the night, and when he went out half-dreaming, he found five slips at the door.

"The witch of the Akafang clan?"

Danzhu raised his eyebrows, and the five slips were painted with five different "vessels", or structures.

"Pulleys, Splits, Axles, Threads, Levers, ....."

Dan Zhu looked at these five things, and suddenly felt a flash of inspiration in his head, he raised his head, and Yu Zai stood not far away, waving his hand to him.

Danzhu was silent for a while, and then said: "The matter of repairing the river, let's not talk about it for the time being, you tell me, what does this mean?"

Danzhu held five wooden tablets, and always felt that he wanted to grasp something, but he just couldn't grasp it, and this mood was very irritable.

"These are the five basic accessories of the instrument, or the method, and the change of the sharp split can be regarded as the mortise and tenon ..... of the Central Plains."

Yu Zai brought a little thing.

It was a delicate, small stone hand mill that could be held in your arms.

Danzhu's craftsmanship is very good, he has a deep attainment in carpentry, and the ships he makes can be pushed and walked on land, although many people think that Danzhu is absurd and nonsensical, saying what to say about land boating, but it is also from the side to affirm his carpentry ability.

Danzhu is a famous shipwright and a famous Go ancestor, but he has not learned the relevant skills of politics.

Yu Zai didn't know that Ah Hong was Danzhu, but Qiao Song told Yu Zai that Ah Hong is a person with very good carpentry skills, as long as you like carpentry, you can be friends with him, and although he likes to talk and raise the bar, he is indeed a good person in his bones.

"It's .... What?"

A design board that Yu Zai took out was picked up by Danju.

"This is mine.... One of my thoughts. ”

Yu Zai said: "This thing, called a fan, I want you to do it, this is the internal structure, in fact, it is not difficult, I can't do it this year, but I can use it next year....."

"Next year?"

Danzhu suddenly stared at Yu Zai for a moment, and then let out a sneer.

Who do you look down on? Is it that Dan Zhu can't hold the chisel, or are your Chifang clan's eyes too high?

It's not that I'm talking badly.... That's it?

That's it!

He slapped the plank on it!

"Give me the plank, I'll give it to you tomorrow!"
