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

[Begin to popularize the history of the development of human weapons!].

[Weapons are the most creative and incredible inventions of mankind. 】

[The advent of weapons has enabled mankind to gradually move towards modern civilization, but at the same time, it has allowed endless wars and killings to continue to this day. 】

[In the more than 5,000 years of the history of world civilization, mankind has experienced more than 15,000 wars, large and small. 】

And these wars are always accompanied by the continuous development and change of weapons. 】

[In the early stage of the development of human society, tools and weapons were inseparable. 】

[With the complexity of society and the progress of craftsmanship, it is natural that tools have changed in various ways due to their uses, and weapons have begun to be redefined at this time. 】

[It is different from hunting tools and tools, and weapons specifically refer to the instruments used in armed struggle between people. 】

[Plays a contradictory role that is both respectful and fearful.] 】

[Since the development of weapons, according to the different uses and combat performance, we generally divide them into three stages: the era of cold weapons, the era of combining cold and hot weapons, and the era of hot weapons. 】

[1: Popular science in the era of cold weapons. 】

[Cold weapons refer to weapons and equipment that do not use gunpowder, explosives and other thermal strike systems, thermodynamic mechanical systems, and modern technological lethal means to directly kill or injure the enemy in combat, or to protect one's own weapons and equipment. 】

[In a broad sense, the era of cold weapons refers to all weapons and equipment in that era. 】

[The era of cold weapons is a period of time before weapons were separated from the tools of production until the appearance of firearms.] 】

[As far as China is concerned, it is the history from the primitive society to the Song Dynasty. 】

[In the primitive society, there was no distinction between military work, and wood and stone were used to hit things, and fighting was a soldier. 】

[Start playing, videos related to the primitive era.] 】

The text-only science popularization in the light curtain ends.

Insert a video about a primitive society.

Commentary is attached.

I saw that the beginning of the picture was in a vast grassland.

A group of wild men, dressed only in straw skirts and animal skins, are desperately trying to escape.

Behind them, several lions were chasing.

This is followed by commentary, as well as subtitles.

Our human ancestors were these fleeing savages, with strong physiques and hairy bodies, which allowed them to withstand the cold weather and harsh living conditions. 】

And unfortunately, they are being chased by several prairie lions. 】

In the picture, several male savages are shouting in a language that modern humans do not understand.

After a short exchange.

They scattered and fled.

The chasing lion was confused for a moment, while chasing one of the wildlings who seemed to be the slowest runner.

With a scream.

The wild man was crushed under several lions and bit off the back of his neck.

The remaining few surviving savages took the opportunity to escape from the pursuit.

Nature is so cruel, in primitive societies, the average life expectancy of men is extremely low, and a large part of the reason is precisely because they have to face a wilderness full of dangers. 】

[Fortunately, only one savage died in the lion's mouth this time.] 】

[The others escaped from the territory of the lions.] 】

Screen switching.

Several wild men who managed to escape regrouped.

Then stop under a large tree.

They whispered to each other for a moment.

One of them went to climb a tree, while the others carried sharpened sticks to let out the wind.

A moment later.

With a joyful shout, the tree-climbing savage came down with an animal skin.

Several people leaned over when they heard the sound.

The wild man opened the leather bag, and there were several eggs lying inside.

[The wild people gave up hunting, but chose a more secure way, digging birds' eggs. 】

[It seems that the death of their companion has made them fearful.] 】

【......】

Qin Dynasty.

The people looked up at the sky.

With the advent of the light curtain, the group of storytellers has increased rapidly.

And they don't need to tell a story at all, just by reading the words that appear on the light curtain, they can earn more money in the teahouse than before.

They listened to the storyteller's translation, and their minds were foggy.

What kind of cold weapons, hot weapons?

I don't understand it at all.

However, the video that soon appeared made it easy for them to understand without the help of a storyteller.

Because there are pictures and sounds.

Look at the wild men that appear in the light curtain.

The people of the Qin Dynasty exclaimed: "These people are our ancestors? "

When they saw the wild men being chased by ferocious beasts, their hearts rose to their throats.

Then they watched the savages dig out the eggs, and they all laughed out loud.

Xianyang Palace.

Many ministers had a heated discussion on the popularization of light curtain science.

"Our Daqin is also in the era of cold weapons, what do you say are hot weapons, hot weapons?"

"Are you stupid, you can't understand popular science, and it's called a thermal weapon if it can explode. "

"Explosion, come, tell me what is going to explode?".

“..."

Then the video of the primitive society appeared.

They immediately changed the subject of the discussion.

"Hiss~~ These unclothed savages are actually our ancestors. "

"Grass skirts, animal skin clothes, not even shoes, how can our ancestors fight wild beasts?".

"Oh no, I'm going to catch up!".

"Hahaha, they also dig birds' eggs, just like us. "

“..."

Ying Zheng looked at the light curtain and completely substituted into it.

His life was bumpy, and he was sent to another country as a proton at the age of a few years and suffered humiliation.

At this moment, see the living environment of human ancestors.

He realized how good his life was when he was a teenager.
