I make a popular science video and all the emperors learn from it!

in the video.

The members of the clan who had been kidnapped to the female savage came to the door and blocked her outside the cave.

The two sides each held wooden spears and confronted each other.

But the standoff didn't last long.

It wasn't until the first grandmothers of both sides came forward that the other party ransomed the female savage with a few hares.

[The two clans will not go to war unless necessary.] 】

[When a member is captured, he can usually exchange food for back, which is a common rule among clans. 】

[The weather is not very good today. 】

[It's only been raining lightly in the morning, I'm afraid I won't be able to go out hunting today.] 】

[Savages can only stay in caves. 】

Dozens of wild men sat around the entrance of the cave, staring blankly outside.

At this time, a little rain fell from the sky.

Boom thunder!

A bolt of lightning fell outside the cave.

Hit a dry tree right now.

The tree was split in two in an instant, and a fire ignited.

This scene happened to be witnessed by all the wild people in the cave.

They looked at each other, confused.

There was a brave savage, holding his head in one hand to keep out the rain, and holding a wooden spear in the other hand to go out to check.

A moment later.

He dragged the burning trees back to the cave.

[This is the first time primitive man has come into contact with flames. 】

What will they do with the flames. 】

The crowd looked at the burning trees and took a few steps back in fear.

After a while.

There seems to be no danger perceived.

They tested the flames with wooden spears.

When the wooden spear was pulled out, he found that the same flame was burning on the wooden spear.

Someone immediately tried to extinguish the flames.

As a result, as soon as his finger touched the flame, he immediately retracted it in pain.

After suffering a loss, they learned wisely.

Sticking a wooden spear into the cleaned hare meat, he approached the flames.

A moment later.

The cave was filled with the smell of meat.

Whet your appetite.

The wild man tried to taste the roasted rabbit meat, and then excitedly gestured something to his companion.

[Primitive people learned the method of roasting meat with a flame by chance. 】

[But unfortunately, this attempt is too short-lived, their understanding of flames is far from enough, and they are still far from being proficient in using it.] 】

Video screen switching.

[Decades later.] 】

[Primitive people have been trying to find flames since the last time they ate barbecue. 】

[Now, they have learned to drill wood for fire.] 】

[And use the flame as a totem and continue it.] 】

[It's sunny today. 】

[Primitive man gets up from the cave and leaves the cave, this phenomenon is called: primitive man got out of the cave!].

[They each held torches, and seemed to want to do something.] 】

Or the same cave.

But it's a different generation.

Dozens of savages armed with torches came to a dense forest.

With a signal.

The people set fire to the plants with torches, and since it was autumn, the dry plants and trees burned when they saw the fire.

In an instant, the fire spread into the forest.

Oh my God! They actually learned to use fire to get their prey. 】

[There are a large number of small animals living in the mountains and forests, and when the fire breaks out, they can only flee in another direction. 】

[And the savages, they only need to wait for the rabbit at the other end of the woods.] 】

[This is indeed a very physically economical way to hunt. 】

[But it will cause devastating suffering to nature.] 】

[Tips: Set fire to the mountain, sit at the bottom of the prison. 】

[Do not imitate.] 】

in the video.

Wait for the fire to subside.

Savages caught thousands of prey!

The most numerous were sheep and a very large pheasant, which were put into wooden cages and carried back to the caves.

...........................................

The ancients were fascinated.

There was a discussion.

"The clan is very disciplined, and they didn't do anything to the female savage, and the next day they took the hare to ransom the person, and they returned it directly, and they felt much more disciplined than the current people. "

"That's right, I misunderstood them and thought that they would do something if we got the female savage back. "

"It's all our faults. "

See the reaction of primitive man when he first discovered the flame.

They clutched their bellies and laughed.

"Hahaha, it's so funny to see their reactions, they actually put out the fire with their hands. "

"Hey, roast rabbit meat, it's the first time they've seen fire?".

"I can't believe it, it's much smarter than my son, who has been in private school for a few years. "

"No, how can you jump directly to a few decades later, what are they going to do with torches?".

"Arson in the mountains! I was too bold to do what I had always wanted to do but didn't dare to do. "

"Caught a thousand prey at once! The old hunter was not so good. "

“..."

Qin Dynasty.

The Confucian scholars finally shut up this time.

I didn't find the reason for the accusation.

But the students of the Legalist family couldn't hold back directly.

Arson in the mountains and forests!

It's a felony!

Even Li Si in the Xianyang Palace frowned slightly, and pondered: "Your Majesty, although this arson in the mountains can get a lot of prey in a short time, it is not a long-term solution." "

He did not convict primitive man.

At that time, people had no concept of law at all.

He just thinks that setting fire to the mountain will do far more harm than good.

It's the same as draining the river and catching fish.

Fusu echoed: "Yes, father, if the people of Great Qin dare to do this, wouldn't there be a good forest in the territory of Great Qin, how can the hunters make a living?"

Ying Zheng nodded slightly.

"The widow also thinks so, just look at it, what's the hurry. "

Whatever primitive man does, it is what has already happened.

He was not worried about the destruction of primitive man.
