Chen Chao thought about the feasibility in his heart, because it would take six days to walk back and forth just to go to the Xian tribe...

But eating without salt is a big problem, although there has always been a situation in the tribe to drink animal blood to replenish salt, but Chen Chao has not drunk it if he doesn't go to that level in his heart, he has obviously felt recently that he often doesn't want to eat, and he often feels that he has no strength.

Especially Chen Chao has really tasted sweet, sour, bitter, spicy and salty, steamed, fried and fried all kinds of beautiful food, and occasionally eats some bland and tasteless things, which is called experiencing life, and often eats, in fact, it is really annoying...

Moreover, the Tian Yuan tribe has long been short of meat, at least there is no such thing as going hungry. And the skin is enough to survive the winter, and the fire is also made, and the stone axe is also made to cut down the trees, and there will be no shortage of firewood to burn in the winter.

Alas, full of warmth and salt!

After lunch, Chen Chao continued to walk, about the time when the sun set, he came to the foot of Tianyuan Mountain, looking from a distance, he could see many animals gathered by the river to bow their heads and drink water, there were wild boars that the hunting team had hunted, and foxes, lions and tigers also had two, and there were four moa...

They don't interfere with each other, as if they have agreed with each other.

Chen Chao looked at the waist-deep weeds around him, a bit like the kind of grass collected by the collection team.

I don't know how feasible it is, Chen Chao looked at the jungle connected to the weeds, and still gave up on this matter...

And these weeds can be dried to make straw ropes, so there is no need to burn them in a fire. Besides, the Tian Yuan tribe only needs a small piece of land for the time being, so where can it be done?

What if there is not enough open space and the walls are crooked?

This is also a problem, and there are large beasts in this vicinity, and it would be a terrible thing to send some of them to live and work in this place without the protection of the city walls.

Otherwise, it is very unrealistic to go back and forth in one day, but it is possible to build a room quickly, and this room must be strong enough and large enough...

It is better to build a high wall first, so that if there are wild beasts, they can quickly hide in the wall, and they can burn torches all the time.

As for the matter of setting fire to the mountain, it is the best policy, and before putting it, the fire prevention isolation zone must be drawn. In fact, even if the separation zone is drawn, a small breeze can bring Mars over and burn an entire mountain.

The whole tribe lives on this mountain, and when a mountain fire burns out, it will be full for the day, and it will be difficult to endure it in the future. So set fire to the mountain, can you come, or not.

Chen Chao walked through the weeds, and from time to time alarmed the rabbits and rats among them, he went to the river to get some water, and boiled a few pieces of dried meat that he had brought.

While the broth was cooking, Chen Chao saw a pair of eyes popping out of the water, and he was startled, isn't this a crocodile? There are crocodiles downstream, why aren't there in the upstream where the Tianyuan tribe is located?

Crocodile skin used to be a good thing, but now it's not!

Moreover, this thing is very difficult to make skin, and it is very fierce, if the children of the tribe do not pay attention to the water by the river, they may be dragged into the water by the crocodile.

Small crocodiles are okay, usually small crocodiles have more natural predators. Even fish can eat it.

But adult crocodiles basically have no natural predators, and occasionally lions, leopards, and even pythons fight crocodiles for accidental reasons, winning and losing each other, and of course being killed if they lose.

Because crocodiles have a characteristic of growing up as long as they are alive, and there is no ultimate size, it is said that there are very, very large individuals that have ever appeared in the world. If there really is such a very long-lived and very large crocodile, then there should be no animal other than a human to kill it.

It's so dangerous, I have to explain the situation to the tribe when I go back, and I usually have to be careful when taking water.

And I don't know if there are any large herbivores suitable for taming in this area, because spring plowing will begin after winter, and it is estimated that it will be difficult to cultivate enough fertile land with the 50 people of the tribe.

You must know that clearing the wasteland is a very hard thing, and without the blessing of animal power and tools, it is a matter that requires the mobilization of the whole family, which takes time and years, and may even cost your life.

This is not alarmist, and clearing the land is really a tiring thing.

What's more, it is a thing like rice, and it also involves the transformation of paddy fields, which is a super project.

Therefore, it is best to find bison and wild horses, which can replace manpower to pull the plow.

Chen Chao was thinking about the bison and wild horses when he felt the ground start to shake.

It can't be an earthquake, right?! But it's not like it's so regular, it's like some big beast is moving around.

He hurriedly looked around, and the meat that had just been put in his mouth fell out.

It's so big!

I saw a giant beast more than six meters tall walking not far away, what concept, about the height of a two-story building.

Hurry up!

Chen Chao quickly evacuated while manipulating in his consciousness, and then searched for the following information in the database.

Giant rhinoceros: Unlike modern rhinos, it has no horns on its head, long head, neck and limbs, and can reach up to six meters tall at the shoulders when it stands, making it the largest known terrestrial mammal, with a long neck and therefore feeds on leaves from large trees.

Chen...

The bison and wild horses didn't see it, but they saw such a giant rhino first...

Can this thing be tamed to pull a plow... If this goods are pulled up by the plow, yo, it will definitely not take a few clicks to turn over dozens of acres of land~~~

And there is such a big giant rhinoceros guarding the camp, what tigers and lions are weak chickens, even if the big moa is coming, they are not afraid! ~

But the wall still has to be built... Stay safe~~

Finally ran out of a distance, and determined that the giant rhino couldn't catch up for a while, Chen Chao began to fight its ideas, what to tame to work, guard the camp, and so on. And this thing eats leaves, let him eat the leaves himself when he is hungry, and it won't be a lot of trouble to find something to feed him.

Chen Chao, who stayed in another place, pondered about sleeping tonight, he collected some wood and prepared to start a fire, it seems that he can only find a random place to sleep tonight.

But fortunately, it is not yet winter, and he also brought two animal skins, and he will be able to sleep next to the fire, but he can't sleep to death, and if he dies of sleep, if he is surrounded by a tiger and a lion to steal his heart, he will have to whine.

Ay... But he's a system boss... Isn't there an artificial intelligence that automatically broadcasts every day... Anyway, seeing it idle, it was idle, so Chen Chao began to call out a friendly electronic sound in his consciousness again.
