Chen Chao really didn't have much to do with these two young couples who were still in the honeymoon period, so he had to pretend to be out of sight and out of mind.

After letting the team rest in place, it's time to prepare lunch. Chen Chao took out the first piece of wood, and then sketched it with charcoal to record the distance he had traveled today.

And Li Nong, the original single dog, also came to the side. Chen Chao painted while explaining to him every time he needed to pay attention to the places.

It didn't take long for Li Nong's little attendant Ban Zhong to come and call the two of them for dinner. Chen Chao saw that the map in his hand was almost outlined, so he put it aside first 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, let it warm, poured it into the pig's urine bubble, and set off again.

In the evening, he found a cave to rest as usual, and finally came to a large river in the afternoon of the third day. I can tell that it is a big river, mainly because the ice on this side has melted a little, and I can see some cracks of ice floating on the surface of the water, and colliding with each other.

How big... Chen Chao can't be sure yet, but there are still quite a lot of places where he can see broken ice floating, and it is estimated that there is no way to walk over directly.

Chen Chao originally wanted to cut down the tree directly and build a raft to go over. But now the ice can't melt, and there is no way to leave, and the raft is on top and it is difficult to move, no matter how you look at it, it feels a little difficult to handle.

Now there are three options, either just take a detour, or see if there will be heavy snow in the next two days, and freeze the river.

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

Chen Chao looked up at the sky, and it was so sunny that it was a little annoying. At a glance, you can see that there is no snow today, and it is estimated that there will be no snow tomorrow~

So after a short break, Chen Chao set off along the river with the Ministry of Commerce.

While looking for a place where you can bypass this large river, you can also look for a narrower river.

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

Let the team members push the wind-powered wheelbarrow outside the cave, some of them to prepare food, and the other part of them 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's very unstable. In the case that there is no shortage of spare wheels, it is better to replace them or replace them.

So he waved his hand and asked Qu, the head of the wheelbarrow manufacturing department who followed him, to take Li Nong and the two of their little followers. In the afterglow of the setting sun, carefully remove the things on the wind-powered unicycle little by little, and then turn the unicycle over entirely, and then prepare to start replacing the wheels.

And the brown witch who was watching from the side, Chen Chao didn't care about him, he can learn to walk, it is his ability.

In the past few days that Brown Witch has followed the team, Chen Chao has also seen it. The purpose of people is to learn, and what kind of joining the gang to earn more commissions is all made up by themselves. The ideals and vision of the brown tribe are much more far-reaching than they think~

However, Chen Chao didn't care about his purpose at all, he was willing to learn, so he would learn. What is on the surface, what can be learned, that's his own business.

As for the fact that when he got along with a little old man in private, he always pestered the little old man to teach him to speak, Chen Chao should not know about it, and let them go.

As for the technology, the Ministry of Commerce and Commerce brought out the finished product this time, and if you want to work backwards from the finished product, it is not so simple to look at it at a glance.

After I get the bronze back this time, who will still use this soil method to make wheels? When the time comes, maybe the two-wheeled bicycle will be made for himself, this kind of unicycle, he can learn it if he wants to~

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

That is the processing of wood, and according to Chen Chao's observation, the Brown tribe does not seem to have a stone axe and other processing tools.

Besides, the stone axe handles wood, which is only a secondary option. When the bronze is returned this time, then I will have to make a bronze saw, and then I will really be able to process the logs into planks properly. There is no longer a need for such thick, uneven wood for wheelbarrow carriages.

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

After changing the wheels, it was dark, and the sky was full of stars, and it looked like tomorrow would be a good day with a big sun.

Want snow? If you want to eat it~

Chen Chao gave up the last bit of hope and decided to honestly cut down trees and pave an improvised bridge tomorrow.

Even though I have been hunting lately, I can not eat the stored food without eating the stored food, but the food I carry is still decreasing at a rate that is visible to the naked eye. Chen Chao carefully inspected it when he unloaded the goods just now, and it was already more than half of it.

So this is also the reason why Chen Chao took the risk of laying wood to cross the river, instead of going around a little farther and trying to find a way to bypass the river.

The team is in dire need of food replenishment!

I can't wait for a few more detours, and it's best to replenish a certain food source tomorrow.

And as long as this river is crossed, it will be the territory of the ring tribe in the past, and when the time comes, find a way to exchange dozens of domesticated black pigs and flower pigs from them. At that time, you can also drive the black pig and the flower pig to the next destination, and at the same time use it as a supplement to food.

Of course, it is definitely necessary to save a few for future breeding. Let the Tianyuan tribe one day live this kind of life with hundreds or thousands of pigs~~

It is estimated that a few heads may not be enough, and you have to find a way to change a hundred or so heads. This will not only be enough to eat, but also enough to feed in the future.

However, this is the current ideal situation, what if the tribe is only willing to change a dozen heads?

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

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

Instead, he used a wooden stick to stir around the cracks in the broken ice, but he didn't get much, much to the disappointment of the little old man.

Although the harvest is not much, I still look at the brown witch and the mushroom girl in a daze.

, what kind of operation is this?

Such? That's it? Can you catch your prey?

Holy, you're kidding the two of us, aren't you?

Don't bully us into being from a small tribe?!

We've seen the world in the tribe!

What they didn't notice was that on the other side of the river, some people looked at the little old man's invincible fish stirring stick and dropped their jaws in shock.
