Chen Chao really had nothing to do with these two young couples who were still in the honeymoon period, so they had to pretend to be out of sight.

After leaving the team to rest, it’s time to prepare lunch. On the other hand, Chen Chao took out the first piece of wood and sketched it with charcoal to record the distance traveled today.

And Li Nong, a primitive single dog, was also nearby. While painting, Chen Chao explained to him every time he needed to pay attention.

It didn't take long for Li Nong's little friend Ban Zhong to ask them to eat. Chen Chao saw that the map in his hand was almost sketched out, so he put it aside and went to sacrifice his five internal organs temple.

After a simple lunch, everyone rested for a while, boiled a few pots of boiling water, poured it into the pig urine bubble, and set off again.

In the evening, I found a cave to rest as usual, and finally came to a big river in the afternoon of the third day. I can tell if it is a big river, mainly because the ice here has melted a little, and some cracked ice can be seen floating on the water and colliding with each other.

How big is it... Chen Chao hasn't been able to determine it yet, but there are still a lot of places where the broken ice can be seen floating.

Chen Chao originally wanted to cut down the trees and build a raft. But now the ice will not melt, there is no way to leave, and the raft is inconvenient to move on, no matter how you look at it, it feels a bit difficult to do.

Now there are three options, either to detour directly, or to see if there will be heavy snow in these two days and freeze the river.

Or find a place where the distance from the river surface is relatively narrow, and cut a few big trees directly on the river surface to make a simple wooden bridge.

Chen Chao raised his head and looked at the sky, it was a bit annoyingly sunny. I can see that there is no snow today, and I guess there will be no snow tomorrow~

So after a short rest, Chen Chao set off along the river with the Ministry of Commerce and Foreign Affairs.

While looking for a place to bypass this big river, while looking for a narrower channel.

Finally, after an afternoon of searching, Chen Chao finally found a relatively narrow river. However, the weather at this time no longer allowed him to cut down trees and cross the river, so he could only walk back a little bit. Walking along the way before, he found a small cave where people could rest.

Ask the team members to push the wind wheelbarrow outside the cave, some of them prepare food, and the other group followed Chen Chao to check the wheels of the wheelbarrow.

Chen Chao checked it, and the wear was already very large. If you don't change the wheels, you should be able to go for a while, but it is very unstable. If there is no shortage of spare wheels, it is better to replace them.

So he waved his hand, letting Li Nong and their two small attendants follow his wheelbarrow manufacturing department. In the afterglow of the setting sun, carefully unload the things on the wind-driven wheelbarrow, and then turn the wheelbarrow over, ready to start replacing the wheels.

As for the Brown Witch who was watching by the side, Chen Chao didn't bother him. He could learn to go, it was his skill.

Chen Chao also noticed the days when the Brown Witch was following the team. People's purpose is to come to learn. Anyone who joins a company to earn more commissions is just to make up for it. The ideals and vision of the brown tribe are far bigger than I thought~

But Chen Chao didn't care about his purpose at all. He was willing to learn, then learn. What is on the surface and what he can learn is his own business.

As for when he was with a little old man in private, he always pestered the little old man to teach him to speak, Chen Chao didn't know it, and let them go.

As for the technology, what the Ministry of Commerce and Foreign Affairs brought out this time is all finished products. It is not something that can be done simply by looking at the finished product.

After he got the bronze back this time, who would use this kind of native method to make wheels? At that time, he might find out the two-wheeled bikes for himself. This kind of wheelbarrow, he can learn it if he wants to.

In fact, it is more difficult for the Brown Witch to learn to make a unicycle, because there is a crucial technical point that must be solved.

That is the treatment of wood. According to Chen Chao's observation, the Brown Tribe does not seem to have tools such as stone axes.

Moreover, stone axe handling wood is only a secondary choice. When I get back the bronze this time, I have to make a bronze saw myself, and then I can really process the round wood into a plank. This kind of thick and uneven wood is no longer used as the carriage of the wheelbarrow.

In general, as long as the bronze can be brought back, all aspects of the production capacity and technology of the Tianyuan tribe can get a qualitative leap.

After changing the wheels, the sky was also dark, and the sky was a little bit starry. At first glance, tomorrow will be a good weather with a big sun.

Want to snow? Want to fart~

Chen Chao gave up the last hope and decided to cut down the trees and build a simple bridge tomorrow.

Even if I have been hunting recently, I can skip the stored food without eating the stored food, but the food I carry is still decreasing at a rate visible to the naked eye. Chen Chao checked it carefully when unloading the cargo, and it was already more than half.

So that's why Chen Chao took the risk of spreading wood to cross the river instead of going around a little further and trying to get around the river.

The team is in urgent need of food supplements now!

Can't wait to detour for a few more days, it is best to add a certain food source tomorrow.

And as long as you cross this river, the past is the territory of the Jie tribe, and you will find a way to exchange dozens of domesticated black pigs and flower pigs from them. When the time comes, you can drive the black pig and the flower pig to the next destination while serving as a supplement to food.

Of course, a few must be reserved for future reproduction. Let the Tianyuan tribe one day be able to live this life with hundreds and thousands of pigs~~

It is estimated that a few heads may not be enough, and you have to find a way to change more than a hundred heads or something. This is not only enough for food, but also enough for the future.

But this is the current ideal situation. What if someone or the tribe is only willing to change a dozen?

Tonight’s food was still mushroom stew and wild boar stew with chestnuts, but because of the river, a certain old man volunteered to take someone to fish by the river.

But because they didn't know the specific depth of the river, they didn't dare to go directly to the river basket fish as they did in the tribe before.

Instead, he used a wooden stick to stir far away in the cracks in the broken ice, but the harvest was not much, which made the little old man disappointed.

Although the harvest is not much, but the brown witch and mushroom girl are still taken aback.

Shit, what kind of operation is this?

such? that's it? Can catch prey?

Damn, are you kidding us two?

Don't bully that we are from a small tribe? !

We have seen the world in the tribe!

What they didn't notice was that on the other side of the river, someone looked at the little old man's invincible fish stick and dropped his jaw in shock.
