Watching short videos of beautiful women dancing, the ancients were all shocked

The teacup was simmering, and the teacup was full of water.

[The essence of human civilization is to boil water and throw stones! ]

On the sky!

There is a pot of boiling water in the teapot, bubbling with white steam, as if jumping happily.

The lid of the pot is jumping up and down by the steam, as if dancing a passionate dance.

Then the picture changes again!

A child is squatting on the ground, holding a stone in his hand, his eyes fixed on a bird not far away.

He threw the stone in his hand with force, but unfortunately he didn't hit the flexible bird.

However, the child did not give up. He immediately took out a slingshot from his pocket and aimed at the bird again.

This time, he used a stone again.

With a crisp sound, the stone flew towards the bird like an arrow.

This time, he successfully hit the target!

People from all time and space couldn't help but have some doubts when seeing the title on the sky curtain!

"Boiling water? Throwing stones?"

"Could it be that the powerful weapons and airplanes in the future were made by boiling water and throwing stones?"

"Is this impossible?"

Above the sky curtain!

The narration also sounded!

[No matter when human beings develop, energy is definitely the most critical factor! ]

[And the essence of energy is boiling water, and the essence of weapons is throwing stones. ]

[From the initial catapult to today's tanks and cannons, they can all be said to be throwing stones. ]

[It's nothing more than throwing stones at the doorstep before, but now they can be thrown into the sea! ]

[Whether it's an intercontinental missile or the two big explosions on the Japanese island back then. ]

[It's essentially throwing stones. ]

[It's just that this stone has changed a little bit, and its power is slightly greater. ]

[Whether this power is great or not is actually uncertain, after all, those who enjoyed it in the Japanese islands have not said a word so far. ]

[And power is energy, and energy is the steam turbine that evolved from boiling water! ]

[Let's talk about boiling water first! ]

[From the birth of mankind to the present, mankind has always been inseparable from boiling water. In the past, boiling water was for eating cooked food and drinking water. Now boiled water can also be drunk, but mankind is not satisfied with this! ]

[So they began to boil water in various ways! ]

[Even if it is nuclear-powered, it is just a change of fuel when boiling water, and the essence has not changed. ]

[So mankind has been trying every means to boil water the fastest and throw bigger stones! ]

[Take the steam engine for example! ]

[Since mankind entered the steam age and discovered the power of boiling water, it has only been a few hundred years since nuclear fusion and nuclear power plants were developed! 】

【The steam engine is undoubtedly the ticket to the new world. It's a pity that it was not invented by us, but it is a unique progress for the entire human race! 】

【Its principle is actually very simple! 】

【Even in ancient times, it could be easily made! 】

At this time, a diagram of the internal structure of a steam engine appeared on the sky!

If you travel back to ancient times, when the basic industry accumulates to a certain level, a new industrial revolution will inevitably begin.

The steam engine is an important symbol of the industrial revolution.

In ancient China, we were the first to use coal!

And the Chinese people's obsession with hot water is obvious to all!

But the use of steam was a long time later than the West!

Today we will learn about the working principle of the steam engine.

Here is the firebox that burns coal, and above it is the water tank, a set of pipes that enter the water, which brings the burning smoke to the chimney.

The water tank is a sealed space where water boils.

In fact, it is very simple, just a boiler for boiling water and a steam engine!

Let's look at the path of steam. First, steam comes out of the air hole and then enters the cylinder through the sliding valve.

Entering the cylinder.

It will force the piston to move forward, and at the same time, the sliding valve slides backward under the action of the twists and turns. At this time, the steam will enter the exhaust port through the outlet below the sliding valve.

[Because the sliding valve moves backward, the next step is that the steam can only enter the front cylinder through this path, thereby pushing the piston backward. ]

[As long as the sliding valve moves forward and backward, two channels will be provided for the steam to push the piston forward and backward, so that we can hear the sound of the steam engine. ]

[Then how this sliding valve slides becomes the key. ]

[Look here, when the piston moves backward, these crankshaft connecting rods will push the sliding valve forward, and when the piston moves forward, these

The crankshaft connecting rod will push the sliding valve backward, so that the steam engine will form a stroke. 】

【Connecting the industrial blood vessels of various places, our army will appear on the border in one day. 】

Under the sky.

Daqin.

Ying Zheng widened his eyes and stared at the huge steel monster that was whirring on the sky, shaking all over.

He was originally worried about how to speed up the Qin army's march!

But now after seeing the steam engine displayed on the sky, he felt that this problem seemed to have a solution.

If he Daqin could develop such a machine, wouldn't his army be able to go anywhere as he pleased?

By then, he will be able to command the army as he pleases and let them win on the battlefield.

The entire map will eventually be filled with Daqin's military flags!

Thinking of this, Ying Zheng was so excited that he trembled all over, his eyes full of greed and ambition.

"Your Majesty, we have recorded the working principle of the steam engine. Please take a look."

A minister came forward with a bamboo slip and said.

Ying Zheng couldn't wait to take the bamboo slip and read it carefully.

He became more and more excited as he read it, with a gleam in his eyes: "Great, this steam engine is really amazing. As long as you master the principle, it is not difficult to make it!"

"Your Majesty is wise, this is the blessing bestowed by God on my Great Qin!" The ministers knelt down and shouted long live.

Ying Zheng nodded with satisfaction, and then ordered: "Pass on my order, immediately summon the world's skilled craftsmen to study the steam engine with all their strength."

"I want to see it made before the potatoes and sweet potatoes are ripe!"

"Yes!" The ministers responded in unison.

As the imperial edicts were issued one after another, the whole Qin State was busy.

Countless craftsmen began to gather in Xianyang City to study the manufacturing method of the steam engine!

Tang Dynasty.

Li Shimin looked at the steam locomotive on the sky, his heart full of shock and confusion.

He couldn't imagine that this seemingly ordinary steam engine had such a huge power that could drive the steel behemoth forward.

He couldn't help but sigh: "Could it be that the airplanes flying in the sky and the steam engines running on the ground in the future are all evolved from boiling water?"

""Do people in the future boil water so much?"

He showed an unbelievable expression on his face, as if everything that happened in front of him made him feel extremely shocked.

Li Shimin widened his eyes and muttered to himself: "People in the future actually used a simple principle of boiling water to create such a steel behemoth. It's incredible!"

If he hadn't seen it with his own eyes, he would never believe that these amazing inventions were evolved from a small principle of boiling water.

Li Shimin's eyes became brighter and brighter. He knew that if he could master this technology, his country would have stronger strength.

"If I also built such a steam locomotive, wouldn't it mean that wherever steam can reach, it belongs to my Tang Dynasty? "

Li Shimin's eyes flashed with ambition, and he seemed to have seen a bright future.

He couldn't help laughing, and continued to talk to himself: "This... Does this mean that God wants me, Li Shimin, to be the world's chief?"

The scene changed again!

Various machines and steam locomotives appeared on the sky!

People in all time and space were shocked!

"Look at that assembly line-like thing!"

"They never dreamed that boiling water would be so awesome!"

"How much manpower and material resources will be saved!"

Then the sky screen changed again, and began to explain what "throwing stones!"
