I am a primitive

Only after the donkey cart is built, can the width of the road be determined according to the width of the donkey cart.

However, according to Han Cheng's vision, the road built this time will be able to accommodate two donkey carts running side by side, and then extend a little further.

This is to prepare for the long-term development in the future.

The Qingque main tribe is close to the Yanshan Mountain, and the Tongshan residential area is close to the Tongshan Mountain. These two things are extremely important strategic resources for the tribe.

That is to say, as long as the two resources are not exhausted, the two tribes of Qingque main tribe and Tongshan sub-district will not decline easily. On the contrary, until the two resources are not exhausted, both places will become more prosperous.

As for the depletion of these two resources, recalling the mining speed at this time and the consumption of the two resources, Han Cheng feels that this is something that will not need to be considered for decades or even longer.

As the Qingquezhu tribe and the Tongshan residential area become prosperous, the demand for this road will become even greater in due time.

By that time, the tribe might have acquired cattle and horses that were bigger than donkeys.

The carts pulled by large animals are of course bigger than the donkey carts.

If the road is not built wider at this time, then the two vehicles will not be able to stagger when they meet, and the road will need to be rebuilt to widen the road surface, which will be time-consuming and laborious.

When Han Cheng and Wu came to the carpenter's room, the carpenter Lie and several other people who were mainly engaged in carpentry and weaving were weaving rattan armor with soft rattan in the shade of the open space outside the carpenter's room.

Rattan armor is complicated to weave, and because it is used to save lives, the quality requirements are very high, so the weaving speed is not fast.

For a master weaver like Lai, the fastest weaving is only two pairs a day, usually one and a half pairs.

As for these apprentices, it is normal to have one pair a day, and sometimes the hands are a little slower, and they can't even weave a pair.

This is still on the premise that someone specially collects and processes rattan.

If they were asked to collect vines again, the speed of weaving armor would become even slower.

But when working, you are not afraid of slowness, but of standing still. Although there are only seven rattan armors at most in one day, thanks to the tireless efforts of Lai and the other five carpenter apprentices, by now, there are almost one rattan armor in the tribe. Hundreds of pairs!

Calculated according to the population size of the Qingque tribe and the size of most tribes in this era that Han Cheng knew, nearly one hundred pairs of rattan armor can already form a rattan armor army!

"Son of God! Witch!"

"Son of God! Witch!"

With the arrival of Han Cheng and Wu, everyone who saw the two stood up and greeted them.

Han Cheng smiled and waved to everyone, signaling them to continue weaving here, then walked to Lie's side, watched Lie weaving the rattan armor for a while, then reached out and patted Lie's shoulder to signal him to follow him.

Lie put down the half of the rattan armor he had woven in his hand, got up, followed Han Cheng and Wu, and went to the house where the sledge and wheelbarrow were stored in the tribe.

Well, after the donkey cart is manufactured, this place can be called a parking lot...

The reason why Han Cheng didn't tell Lai about these things in front of the carpenter's room was because looking at the sledge and the wheelbarrow here could better explain the donkey cart and let Lai have a more intuitive feeling.

On the other hand, it is to prevent the other apprentices from being distracted and delaying the weaving of rattan armor.

Well, in essence, God Son Han is also a person who loves to watch other people's hard work...

Following what Han Cheng said, the lame eyes that seemed a little dazed because Han Cheng and Wu, the two giants of the tribe, came to find him together became brighter and brighter, and then they seemed to be flickering with light inside.

Lame with an excited expression, looked at the many sledges stored here, and then at the wheelbarrow over there, rubbing his hands back and forth excitedly.

So smart!

The Son of God is so wise!

I also once felt deeply regretful that the sledge could only be used when heavy snow fell, but this regret was just a regret, and I didn't think of any way to make up for this regret.

But now, with a few light words from the Son of God, this matter was resolved.

A wheelbarrow can run with round wheels and can be pushed by people, so why can't I think of putting wheels on the sledge?

In this way, even if there is no snow, the animals in the tribe can also pull this kind of sledge with wheels.

And one sledge can hold more things than four wheelbarrows.

Once such a thing is manufactured, then...

"Son of God!"

The more I thought about it, the more excited I became, I came to Han Cheng and saluted Han Cheng deeply, and shouted respectfully to express my deep respect...

-------------Chapter Dividing Line---------------

(Rewards for book friends AT books will be added on 7/12, 8/18, too many words, I can't put it on the chapter title, sniffing...)

Many things in the world are like this, just separated by a layer of window paper, you only need to pierce it, and you can get a brand new result immediately, and it is not impossible to discover a brand new world.

It's just not easy to pierce this membrane.

Just like lame now.

Putting things on wheels and making them into carts for transporting things is the most normal thing for people in later generations, but it is very difficult for people in the tribe to think about it.

If it weren't for Han Cheng to make a point, even on the basis of today, the people in the tribe can think of things like adding wheels to the sledge, making vehicles, and putting deer and donkeys on them to pull the carts. It's not easy.

You only need to look at Lai's reaction at this moment to know this.

In fact, this is the biggest advantage of people who travel back, because with the knowledge that I don’t know how many years ahead, when they deal with the things they encounter, they often feel very common, or even taken for granted, in this era. In the eyes of everyone, there will be an uproar.

Looking at the lame who saluted deeply to himself and respectfully praised the 'Son of God', and the witch who joined him later, Han Cheng was full of emotion and thought this way.

It's not by accident that Lai became the number one carpenter of the Qingque Tribe. You only need to look at the way he looks so excited and eager to build it immediately after learning about the donkey cart.

The most critical part of making a two-wheeled donkey cart is not the sledge-like body on the top, but the wheels below.

This is really a very technical thing, especially the bearings that connect the two wheels.

Together with the weight of the car itself and the weight of the things on it, it will be pressed on the bearings first, and then shared on the two wheels. The weight it bears can be imagined.

Before there was no bronze in the tribe, hardwood alone was enough to make the axles of some wheelbarrows, but it was difficult to make hardwood bearings for two-wheeled carts like donkey carts that were destined to carry a lot of things.

Therefore, the manufacture of donkey carts is not only the work of Lai, the carpenter, but also the work of Hei Wa, the craftsman who makes the molds, and the second senior brother, who specializes in copper and iron besides slings.

Han Cheng said that he needed to call the second senior brother and Hei Wa to come and study together, but before he had time to go out, the extremely excited carpenter limped and ran quickly to find the two of them.

At this speed, Han Cheng, a man with good legs and feet, actually felt a little unmatched.

Not long after, the second senior brother and Hei Wa limped in excitement, and also came over with excited faces.

"Son of God!"
