The division of territory is also very clear, basically the place that can be reached and returned on foot in a day, and the territory of each tribe is demarcated within a radius.

This ensures that there is basically no overlap between the tribes.

The second brother explained this meaning to the Son of Heaven again, and then said, "Son of Heaven, like this... Yes, you can. ”

Wang Tian understood what he meant, but as the so-called side of the couch did not allow others to sleep soundly, Wang Tian still felt uncomfortable in his heart.

But considering that he may also have to go to other people's territory to collect copper and iron ore in the future, he had to explain: "Dear fish, I don't know that it is from your river tribe, you and we are friendly, this is no problem, but you should be able to understand my anxiety. ”

The fish didn't speak, he patted his chest in understanding.

"How is your tribe doing? The water level should have receded! Wang Tian asked further.

Under the second brother's translation, the leader of the River tribe continued: "It has not completely retreated, and it is still difficult to travel. And said that he wanted to return to the tribe as soon as possible.

Wang Tian invited the leader of the River tribe to come to his tribe as a guest.

Wang Tian is playing a careful trick, of course, the river tribe at this time is impossible to come as a guest, and the empty favor is not sold for nothing.

If there was a 1% chance that he would come, then Wang Tian would definitely not invite him.

"We don't have time, we have to quarry as soon as possible," the fish asked the second brother.

The stones of this era were basically of little use except for polishing stone tools.

He was puzzled to see that the Tianlong tribe had also collected so many stones, and he was worried that he would not let them quarry because of this.

"That's no problem, what our tribe needs is this kind of stone, and you can pick the rest here." Wang Tian picked up a piece of limestone and handed it over.

"We need a lot of this stone, and this one you must leave for us." Wang Tian clearly put forward his own conditions.

Wang Tian saw that the fish was obviously relaxed, he wanted hard granite and basalt, and if this kind of limestone existed, he didn't mind using it for emergencies.

But they have all been picked up by Wang Tian and others, and if he needs to mine them himself, of course he will not go to limestone.

The main component of limestone is calcium carbonate, which is affected by carbon dioxide, carbide and water vapor in the atmosphere, and is also easy to weathering and dissolving, which makes the surface lose its luster quickly.

Therefore, except for a few relatively stable and durable varieties such as white marble and artemisia leaf green, which are pure and have few impurities, they can be used outdoors, and other varieties are not suitable for outdoor use.

Not to mention that it was to be used for soaking in water, although primitive people did not understand the reason, but which kind of stone was more suitable, life experience can still tell them.

After saying that he only needed hard stones, he ignored the people of the Tianlong tribe and led the people of his tribe to mine stones.

Wang Tian was not in a hurry to go back at this time, he wanted to see how the people of the River tribe mined hard granite, so that it would be convenient to understand the civilization of other tribes.

In fact, the quarrying method of the river tribe is also more ingenious, they first dig out the gravel and soil parts of the fault to clean up the fracture surface of the granite.

Then a wooden tip made of hard wood is hammered into the crevices of the stone to break and separate.

Because they also use waterways, no matter how large the stones are, there is no problem with transporting them.

Seeing that there was nothing to learn from, Wang Tian beckoned everyone to put the stones on the bamboo raft, and then five people from each bamboo raft transported the stones to the factory.

The remaining 11 people plus Wang Tian returned to the tribe by land, and the second brother still accompanied Wang Tian as protection.

On the way back, Wang Tian's eyes have been fixed on the dogtail plant, the world's most primitive agricultural crop, China is the first country in the world to grow millet.

Millet was first cultivated from dogtail grass, and all the corn varieties in the world were introduced from China.

Wang Tian asked the second brother where he knew where there was more of this grass, and the second brother pointed to the north where they were hunting.

The second brother told Wang Tian that in a col over there, there was all such grass. But he didn't know why Bai Zi was looking for this grass.

This grass seems to be of no use except for the fire, and his grass seeds are so small that they can be blown away in one breath. Not edible at all.

Wang Tian estimated that the earliest corn cultivar should be at least a mutated variety.

Primitive people should not have imagined that with ordinary dog tail grass, they could cultivate practical food.

As long as there are enough of them, there will always be variations in them, so that even if they are re-breeded, it will be much easier.

Wang Tian asked the second brother to take him there now, but the second brother pointed to the people of the tribe and signaled that Wang Tian's number was too small, and it would be dangerous to go like this.

In autumn, bushgame is abundant and hunters are abundant. There is no clear boundary between the two roles of prey and hunter, and if you accidentally become a yellow finch behind, it becomes a snack for other hunters.

Wang Tian knew that what the second brother said was the truth, and he no longer insisted, he had already made up his mind that after the lime was fired, he would go out hunting with the leader.

Just as Wang Tian was about to leave, a tree as tall as him attracted his attention.

Isn't this the north? How can there be papaya?

What he saw was a shrub about one meter long, with a straight trunk, evenly spread out around the leaves, and the entire crown of the tree was like a canopy, and the shape of the plant was very beautiful.

Wang Tian hurriedly stepped forward and wanted to use the firearm in his hand to pull out the leaves and observe carefully.

The second brother stopped him, and made him understand that this can't be touched, and if he touches it, it will cause itching all over his body.

Wang Tianjin stepped forward to see that although this kind of tree was very similar to papaya, the snakeskin lines on the trunk clearly told him that it was not papaya.

Its trunk is gray and white, like pebbles of two colors, and it resembles snakeskin, and its leaves are different from those of papaya. Combined with the second brother's words, touching it will cause itching all over the body, which reminds him of a food.

Such a plant shape will itch after touching, this ......, is it konjac?

In Wang Tian's memory, konjac coincides with this thing.

Konjac is a rich food in Wang Tian's memory, and it is very respected and eaten in later generations, with the effects of lowering blood sugar, lowering blood lipids, lowering blood pressure, laxative beauty, etc.

The legend on the Internet is that it is a fetish for weight loss, it is low in heat, low in fat, low in sugar, to put it simply, it is not only to satisfy the appetite, but it is impossible to feel full. Its three lows can also cure the three highs.

Primitive people needed precisely high-fat and high-calorie food.

Of course, it still has nutritional value, at least the plant fiber is rich.

This discovery made Wang Tian a little depressed, and what he wanted was food that could be used as a staple food. God gave it to himself, what does it mean to be this kind of konjac that you can't eat enough?

Primitive people should not have the hidden danger of the three highs, this kind of wealth disease is.

Despite this, when it comes to a food that can be eaten, Wang Tian will not let it go.

Konjac is poisonous throughout the whole plant, especially the roots that are used for food. It needs to be processed before consumption.

According to legend, the Chinese began to use konjac very early and it was related to Emperor Yan.

Ancient legends: Xuanyuan Yellow Emperor made clothes, Emperor Shennong tasted herbs, and Emperor Yan grew food. The wife of the Emperor Yan is the reincarnation of Ma Po Niangniang, the husband sings the wife and travels all over the land of China, looking for all kinds of food that can be eaten.

One day the couple rode the white crane, came to the tiger on the white crane cave mountain, only to see a lot of people all over the mountain, especially the elderly, sick and weak, women and children fell to the ground, it is countless, Ma Po Niangniang took a closer look, they all foamed at the mouth, convulsions, so the local land lord called, only to know that it was from the west to the sky a devil scattered these rhizomes that shot the tongue, because of the three years of famine here, people were hungry and did not choose food, and fell down due to the attack of poison after eating.

The land lord said: I have heard, these black stones sown by this devil are called konjac and konjac, and if you want to eat it, you must add a kind of medicine, and you can only eat it after it is cooked thoroughly.

The concocted konjac has the effects of satiety, beauty, intestinal cleansing, and detoxification, but this secret recipe is in the hands of the devil, and he refuses to take it out.

Ma Po immediately set up a seven-star stove on the tiger hill, cut down cornwood, burned water to the west heaven to boil the devil in the west sky, boiled for seven seven and forty-nine days, and finally burned the devil into ashes, boiled into alkaline water, and soaked in alkaline water with stove ashes, which was used to cook konjac.

In this way, the hemp flavor was boiled, and it was no longer astringent. It tastes delicious and has a lot of flavor.

Ma Po, the wife of the Yan Emperor, selflessly dedicated this secret recipe of grinding konjac with alkaline water to cook konjac to the world.

Since then, konjac this green food has raised generations of people on the land of China, and later for people to commemorate the merits of this Ma Po Niang Niang Fetus, and respectfully call Ma Po Niang Niang Fetus as the Stove God - Husband.
