After all, they are all experts in playing with mud, and most of the earliest batch of clay pots and bowls came from their hands~

In the end, most of the construction team members who had just been free returned to the pottery team, and these people, led by One-Eye and Wu, all sharpened their knives to the mud.

After watching them start making clay embryos, Chen Chao explained to the little old man that the clay pots made this time should be stacked together.

After the explanation, Chen Chao led Da Zhuang and his team to start work, and the location was chosen to be the place where the tribe usually cooks.

Directly put the piece of yellow clay that built the house in a clay pot, and some people from the grass tribe moved a batch of bricks, and you can start work directly.

Chen Chao used the clay pot to make a gesture of the position that needed to be set aside, and took Da Zhuang to do the first one, and after confirming that Da Zhuang had learned, he went to work on other things as a shopkeeper.

Because he has something else on his mind, he has recently awakened a lot of tribes and populations. Therefore, Chen Chao plans to go out in the near future to get a group of people to come back, and by the way, to get some bronze mines back.

And Chen Chao has been thinking about this matter recently, and now there are several ways to want the population.

1. Influence each other with love and let them join the Tianyuan tribe, (of course it's impossible, now this strength, it's good not to be influenced by others' force~~)

Second, take resources in exchange, the tribe now has resources: stone pots, straw sandals, straw ropes, rattan baskets.

Third, turn on the plunder mode, and those who do not join will destroy the whole clan (it is okay to destroy small tribes, but not large tribes, and they will only be counter-killed.) It's not the original intention, and the aftermath is too great. ）

So the first and third options are directly passed, and the second can. In addition, Chen Chao also started the idea of another small tribe, planning to absorb their entire clan.

After all, it was winter, and those small tribes would soon starve and freeze to death if they didn't have food and skins to protect them from the cold. Therefore, at this time, there should be a great success rate when a wave of charcoal is sent in the snow.

And those medium-sized tribes should also be happy to get some clay pots that can be heated over the fire. If you can reduce a few mouths to eat, I believe they will not refuse.

As for the big tribes, it is as a last resort. Because it is not clear whether this large tribe, which can barely survive the cold winter, has any plans to exchange populations. However, it is okay to exchange some of the animals they raise, and some specialties can also be exchanged, preferably seeds and other things.

Moreover, Chen Chao is also afraid that he will be blackened by the other party, plus several big tribes are far away from the Tianyuan tribe, he may not be able to go there, and even if he goes there, he will not have enough resources to exchange it.

But if you choose the second option, you have to consider how the resources are transported, and the problem of transportation capacity is not realistic, and there are mainly more than a dozen horses. And Chen Chao felt a little reluctant, besides, if the wild horse has not been domesticated, it will be troublesome to carry people, let alone pull the carriage for hundreds of kilometers.

Now the bronze hasn't been brought back, and the bronze horseshoe can't be made, plus pulling heavy objects. This round trip is almost as cost-effective as this horse.

Moreover, there are already people in the Tianyuan tribe who believe that wild horses have spirits, otherwise how could they be obedient and brought back from such a far away place by the deputy leader?

So in the absence of capacity, Chen Chao can only use people as capacity.

Fortunately, he is not interested in carrying a lot of things to the major tribes to fight alone, so he will still take a group of people with him, but this matter must be discussed with the little old man first.

Since considering people as the transport capacity, it is certainly not possible to carry hundreds of clay pots and bowls on the shoulder to replace people, one is unrealistic, and the other is that the efficiency and cargo capacity are too low.

And the two-wheeled vehicle can't be considered, no way, there is no capacity, if this time I can go out and get a batch of bison and other animals with good endurance to come back, it would be great.

Then you have to get on a wheelbarrow. The wheelbarrow is also known as the 'chicken bus' and the 'sheep's horn', mainly because it is used to drive with a "clucking" sound non-stop, and the front head is sharp, and the back two push handles are like sheep's horns.

A unicycle is usually capable of carrying the weight of six people at a time, and instead of putting a large amount of weight on the person or animal pulling, it distributes the weight evenly between the puller and the wheel itself.

Moreover, it can run on narrow roads, and its transportation capacity is several times larger than that of human load and animal load load. They can work in the countryside and fields, but they are also convenient for walking on rough roads and hills

But if it's just a wheelbarrow, it's all about manpower. It's too much, I can't bear to think about it~

So Chen Chao decided to go directly to the wind unicycle (interested students can check Baidu, the keyword is 'wind unicycle' to see the picture, it is an old photo of the Republic of China).

After the wheelbarrow is made, a cross rod is added to the front of the car, and a prismatic sail is tied to the pole, but this can only be replaced by animal skin for the time being.

Chen Chao first thought of two styles of unicycles, the first is a funnel-style unicycle, and the second is a flat plate at the bottom, and then some railings are added around it to prevent things from falling.

The funnel-style wheelbarrow is too restrictive, and although it looks a little more stable and is suitable for transporting building materials (sand and bricks), etc., it is very limited in what it can carry.

The second type can hold a lot of things, but considering that this time it is mainly pottery and other materials. Pottery is good at everything, but it is fragile and heavy, not as good as iron pots and bowls, porcelain!

Therefore, Chen Chao decided to combine the two, and the surrounding railings were changed to wooden boards, and movable wooden boards were added in the middle as partitions.

In fact, the pottery is also placed in rattan baskets, which are blocked by rattan baskets and hay, and the problem of fragmentation should be well solved.

In this way, it does not necessarily need to be separated by wooden planks in the middle, after all, adding movable wooden plank partitions still requires a certain weight.

And this time, I was rushing to lead a large number of people to a long-distance attack of more than 300 kilometers, and in addition to the unnecessary weight addition of pottery, it was as little as possible.

After deciding on the specific style of the wind-powered wheelbarrow, Chen Chao still has two problems to solve, one is the outermost wooden board production, and the other is the most important thing of the wheelbarrow, the production of wheels.

In terms of wooden planks, if the Tianyuan tribe no longer has a saw, it is unrealistic to directly deal with long-distance wooden planks, even if they want to make them into the flat and thin planks of modern times.

There is indeed a plant with sharp serrations at the edges, but it is not practical to handle large wood with that, and it is still possible to handle small twigs the thickness of the wrist, as long as you are patient.

Therefore, if you can use a stone axe to divide a 6-70 cm tall log into quarters longitudinally, you can be called a master.

So Chen Chao could only make do with using a pile of thick wood as the outer frame of the car.

When it comes to wheels, there are two options.

One is to bake the wood and bend it, and then bend it into the desired arc.

The second is to directly find a log of the right size to make the wheel.

It is true that the wood can be bent, although there is no limit to the size of the wood in this method, as long as it is long enough, there is no problem.

But there's really nothing to hold it in place right now. So the option of baking bent wood was directly passed by Chen Chao.

Then there is the second option, which is to find a log of the right size to make the wheel.

He went to the cave to look for the wood mountain, and only then did he find a few logs that fit the size of a wheel, because there were too few logs suitable for wheels.

The main reason is that Chen Chao plans to burn through the logs at both ends in the middle, burn a round hole that is large enough, and then leave enough space for the spokes to be installed.

This means that the wood has to be large enough.

In fact, you can also use logs (rolling logs) directly, without any treatment. But this is heavy, and it is easy to crack along the wood grain.

If it's hollow, it's much lighter. In addition to saving effort, it can also greatly improve the travel speed.

However, when the time comes, you can make a few more wheels and carry them with you on the road. Placing these pieces of wood next to the pottery can also effectively reduce the collision between the pottery and the pottery.
