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

Qin Dynasty.

Never mind Daqin Heavy Industries, the world’s first assembly line...

Ying Zheng was not interested at all.

He could only know one thing now.

Why did the Qin Dynasty collapse so quickly?! ? who is it?

Who made the iron-blooded Qin Dynasty that he forged with his own hands collapse in less than twenty years?

Ying Zheng was as anxious as an ant on a hot pot.

He looked at Fusu aside.

Could it be Fusu?

"Yes, this man is pedantic and unfit to be an emperor!"

But even so, it is impossible for the huge Qin Dynasty to fall so quickly.

Fusu alone is useless.

You can't let his officials be useless too.

The two brothers Meng Tian and Meng Yi are completely the pillars of the Qin Dynasty. With these two people here, what enemy can defeat the Qin Dynasty!

He noticed Ying Zheng scanning his eyes with disappointment.

Fusu lowered his head in shame.

On the other hand, the other princes tried their best to attract attention.

The young master looked ecstatic:"This prince's The opportunity has come!

Fusu, he is finally hated by his father!

Haha, Fusu, today too.

Hu Hai is even more exaggerated, standing on tiptoes with a happy expression on his face.

Look at me, look at me!

Father, look at me...

Ying Zheng turned his face away. All these princes were disappointed.

Don’t even look at it!

Wait, since nothing big will happen in the country.

The problem lies abroad.

Foreign invasion?

The only people who can be called enemies of Qin are the grassland people.

Huns and barbarians.

Ying Zheng's eyes narrowed and he murmured:"It must be a foreign invasion!"

【Surprise or not? Unexpected or not?】

【Q&A session!】

【May I ask when the Qin Dynasty was established and when it fell?】

【Option 1: 221 BC, 206 BC】

【Option 2: 222 BC, 206 BC】

【Option three: 220 BC, 208 BC】

【Option 4: 221 BC, 207 BC]

Ying Zheng’s eyes were bloodshot! this...What's the difference between this and rubbing salt into his wounds!

It’s heartbreaking to kill people!

"Option four!"

Ying Zheng almost shouted. He may never forget these two numbers in his life.

【correct answer!】

【Congratulations to Qin Dynasty Yingzheng for successfully answering the question】

【Obtained: Improved iron smelting technology, manufacturing process drawings of stirrups and horseshoes. 】

The next second.

A (bjbe) book and two drawings appeared in his hands.

The sadness never goes away, it just moves on to other people.

Ying Zheng decided to let the grassland people feel his pain!

He quickly looked at the two drawings in his hands

【Stirrup:】

【It is a pair of footrests hung on both sides of the saddle, which is used by the horseman to step on the horse when mounting and riding.】

【The function of stirrups: not only to help people get on the horse, but more importantly, to support the equestrian's feet while riding, so as to maximize the advantages of riding and at the same time effectively protect the safety of the equestrian.】

【horseshoe:】

【Also known as horseshoe, it is an iron hoof-shaped object nailed to the hooves of horses, mules and other livestock.】

【A horse's hoof is made up of two layers. The layer that is in contact with the ground is a layer of hard cutin about 2-3 cm thick, and the upper layer is living cutin.】

【When horseshoes come into contact with the ground, they will fall off quickly due to friction from the ground and corrosion from accumulated water. The purpose of nailing horseshoes is mainly to delay the wear and tear of horseshoes.】

【The use of horseshoes: not only protects the horseshoes, but also makes the horseshoes grip the ground more firmly, which is beneficial for riding and driving.】

"It's so magical."(To read Baoshuang novels, go to Feilu Novel Network!)

Ying Zheng took a deep breath.

After reading the introduction, he already knew the functions of these two things.

In short, when placed on the battlefield, the former can increase the strength of soldiers. Combat power, the latter can make horses run farther.

Another book is more interesting.

It is iron smelting technology[]

The reason why Da Qin used a large number of bronzes was not because there was no iron to use, but because the iron smelting technology was backward.

Now, that just makes up for it

"Well, God helps me. Ying Zheng waved his hand and immediately ordered:"Call the people of the Mo family into the palace to make stirrups and horseshoes for me.""

It didn't take long.

Everyone from the Mo family arrived.

After seeing the iron smelting technology, everyone was very excited.

They had been worrying about how to smelt iron efficiently recently, but now their Majesty has solved it!

"Don't worry, Your Majesty, I can make these stirrups and horseshoes within one day, ensuring that each one is exactly the same and can be used directly."

After receiving the promise from everyone in the Mo family,

Ying Zheng could only wait patiently.

After only waiting for half a day, the stirrups and horseshoes were delivered to him.

Ying Zheng looked at the two strange-shaped things and ordered to his side:"Bring a horse war horse."

After a while, a majestic war horse was pulled outside the palace.

Stirrups and horseshoes had been put on it.

"You protect His Majesty while I mount the horse and try it myself."Meng Tian came out and gave orders to thousands of soldiers.

"promise!"

Thousands of voices frightened the war horse, which made it stomp a few steps on the spot, as if it wanted to escape.

Meng Tian came to the horse, gently stroked it, and comforted the frightened horse.

Then, he looked at the stirrup.

The whole thing resembled a The ring was round at the top and flat at the bottom.

It was just enough to put down one foot.

Putting his foot on the stirrup, with a little force, he jumped on the horse.

"nice one!"

As soon as he got on the horse,

Meng Tian immediately felt the beauty of this thing.

Indeed, with this thing, getting on and off the horse is very simple.

He even suspected that even a woman could easily get on the horse without training.

And there was a place to put her feet.

You won’t be so tired when riding a horse.

Before, your legs were stretched out, but once you ride for a long time, you can barely feel anything in your legs when you get off the horse.

"drive!"

The horse's hooves made a crisp sound on the ground.

Meng Tian knew very well what the sound was.

The sound of the collision of iron tools.

He didn't quite understand how the iron tools were installed on the horses' feet?

It was just like people putting on shoes.

But One thing is certain, a war horse wearing iron shoes will be able to run farther.

Moreover, once the war horse steps on the enemy while running,...

He couldn't even imagine how miserable the trampled enemy would be.

Walk around the main hall twice on horseback.

Meng Tian discovered something that surprised him even more.

He seems to be able to stand up on his horse and fire a crossbow at the enemy!! ?

"My dear, what's wrong?"

Ying Zheng looked anxious and asked directly......
