I hand over the Wanjie trading system to the country

Because Blue Star became an agricultural star, the entire Blue Star started a breeding and planting boom.

The stocks of major agricultural groups soared, and countless workers resigned and went home to farm.

And the deal with the prehistoric world is basically over, and now is the learning time for the prehistoric world.

Orc tribes learn hunting skills and the manufacture of trap tools.

The Human Alliance learns farming techniques and more advanced tool making.

"This wild rice, if we bring it back and plant it, won't it become domesticated?"

"Why are we breeding them again?"

As a learning representative of the Human Alliance, Kai is simply the latest version of One Hundred Thousand Whys.

There are countless questions waiting for the instructor every day, and the instructor almost collapsed when asked by him.

"And these little piggies, why are they castrated?"

"Isn't it necessary to save more piglets to continue raising?"

"Why can't sprouted potatoes be eaten? But sprouted garlic can be eaten?"

"The fire also comes from the sky, and we can make it ourselves."

"That rain comes from the sky, why can't we make it?"

"Oh? You can make rain? Then why don't you teach us?"

"Can't learn? You don't teach us why you say we can't learn?"

"Chemistry? What is chemistry?"

In fact, it seems that people from the main world are teaching people from the prehistoric world all kinds of knowledge.

In fact, the main world has learned a lot from the prehistoric world.

Although some methods seem very clumsy, they are extremely practical.

The primitive people in the prehistoric world were not useless, they also had their own complete system.

Although many animals and plants have been traded back from the prehistoric world, they are actually of no use to the cultural inheritance of the main world.

Those things have been extinct for too long, and there are no records or applications in history.

For the main world, the animals and plants of these prehistoric worlds may be used for viewing after the research on them is over.

It may also be because the prehistoric world is too dangerous. Most of the animals in this world are relatively fierce, and the plants are more or less poisonous.

Many small herbivores in the public perception of the main world, their "ancestors" in the prehistoric world were omnivores.

Pointy teeth, sharp claws, skilled hunting skills.

In the prehistoric world, a place where the law of the jungle is vividly interpreted, the size of the herbivores is bigger and bigger, and the defense is full.

And the colors of those small birds are actually not very good-looking, they are all dusty, and they are basically invisible when they enter the forest.

The larger the body and the stronger the fighting power of the bird, the more colorful the color.

After the orcs learned to use the large-scale hunting of the main world society, several adult giant raptors were caught.

Gigantoraptor stood twice the height of a human body, weighed 1.5 tons, and had a turtle-like beak.

This is the largest feathered dinosaur archaeologists have ever found.

According to Gang Ya, Gigantoraptor was notorious throughout the prehistoric world.

Relying on his ability to fly and his huge size, he often rushed directly into the protection circle of a group of dinosaurs to snatch those small dinosaurs.

The breeding of the Human Alliance also often encounters the poisonous hands of the giant raptor.

Although Gigaraptor is huge in size, it flies extremely fast and is extremely difficult to capture.

The means of protection in the prehistoric world can only be obtained from nature.

Those protective nets woven by vines and thorns are simply vulnerable to the giant raptor, and can be easily torn by its sharp claws.

Fortunately, the Dinosaur Island in the main world has something like an electronic fence, otherwise it would be a headache for a while.

Don't wait for the small dinosaurs that have been traded back with great difficulty to become the food of Gigantoraptor in the end.

The transactions of the late and prehistoric world are almost all kinds of knowledge.

There are very few seeds traded to them, and the prehistoric world is completely different from the ancient times.

Although the food production in ancient times was very low, humans at that time had learned to plant and breed.

Moreover, the whole society is developing at a high speed, so there is absolutely no problem in providing them with seeds.

For the prehistoric world, providing them with high-yield grains would have done more harm than good.

Just as we cannot directly provide the ancient world with fully modernized weapons, we still cannot make too many strides all at once.

They were given a small amount of seeds, one of sugarcane and beet, which can be used to make sugar, and one of sweet potato.

Sugar can provide high calories, and sweet potatoes can provide high satiety.

As for other corn, millet, etc., they compiled an atlas for them based on the pictures restored by the experts.

When the time comes, let them find them by themselves according to the atlas and come back to domesticate them slowly.

Speaking of it, teaching is the most perfect technology in the world, and it should be salt making.

Salt is an indispensable thing no matter which world you are in.

In the long history of Huaguo, salt has once become something that can directly replace currency in transactions.

In the prehistoric world, whether it was humans or beastmen, in fact, they were not to the extent of pursuing the taste of food.

For them, as long as they can eat enough.

Compared with bloody raw food, food that has been roasted with flames is already extremely delicious.

Salt is another thing they would go on their own.

Just like those animals in nature now lick the salt crystals precipitated on rocks.

The same is true of humans and orcs in the prehistoric world. They actually don't know what this is.

I only know that if I don't lick these white crystals for a period of time, I will lose my strength.

In the Human Alliance, a group of prehistoric sheep were specially domesticated to find stones that can precipitate salt.

It turns out that no matter it is the prehistoric world or the main world, sheep are the animals that like to eat salt the most.

When Chunuo returned to his hometown in the countryside when he was a child, he saw his relatives feeding the sheep with a large piece of salt.

The sheep ate with relish, and Chuno's throat hurt when he saw it, and he felt so salty when he really watched it eat.

And it is precisely because of this characteristic that sheep are the most powerful animals in nature to find salt.

The sheep in the prehistoric world look similar to the argali in the main world.

However, the coiled horns on its head are larger, and it runs fast. Its teeth look similar to those of the current sheep, and its eyes are cute and cute.

It is about the size of a zebra, with curly hair all over its body, and it feels very good to the touch.

But he is not timid at all, and he likes to take the initiative to provoke and attack other animals.

Chuno, who was deceived by the appearance of the prehistoric sheep, touched a lamb a couple of times, but was knocked backward by the mother sheep for more than three meters.

Like a bowling ball being ejected, it knocked over a dozen people behind him.
