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

Qin Dynasty.

The ministers present were all staring intently at the light curtain.

I'm afraid of missing a single detail.

"Gunpowder made from a mixture of potassium nitrate, sulfur, and charcoal powder is called black powder, or brown powder. "

"The content of sulfur and nitrate is close to 1 to 3. "

"This is the detailed ratio of black powder!"

"Write it down!"

A group of scholars worked hard to write books.

Thanks to Daqin, he now got out the paper, otherwise let them engrave words on the bamboo slips.

I can carve my hands into smoke!

Ying Zheng carefully compared it on the side, but any minister made a mistake or wrote too slowly.

He would give a reminder.

"Whew..."

"Back to Your Majesty, I'll wait for all the records to be completed. "

The ministers stood up and replied respectfully.

"Hmm. Ying Zheng agreed, and then shouted: "Go and call Xu Fu and the others." "

Not for a while.

Xu Fu arrived with more than a dozen Fang Shi.

Ying Zheng directly handed them a note and instructed: "This is the recipe for black powder, you should make it as soon as possible." "

"Yes, the villain will definitely live up to His Majesty's high expectations. "

After that, Xu Fu grabbed the formula and took the monks back to study.

Do everything.

Ying Zheng stared at the light curtain angrily, and scolded angrily: "It's a good Qing Dynasty, even cannonballs can be faked, what else can't they do?"

Han dynasty.

Liu Bang got up to inspect.

"Hey, everybody, take a quick note. "

"With this black powder, my Han family is worry-free. "

Civil servants are responsible for keeping records.

Among the generals, Han Xin took a few steps and admonished: "Your Majesty, when the black powder is made, the ministers will take the initiative to attack the grassland!"

Hearing this, Fan Hao let out a rough laugh.

"Yes, Your Majesty, we are still afraid of the Huns of birds, and that Maudun boy is not afraid." "

"The minister is also willing to ask for soldiers!"

Liu Bang's eyes swept over the two.

After a moment of silence.

He couldn't hide his joy on his face, and shouted repeatedly: "Okay, good, when the time comes, you go together, and you must eradicate the Xiongnu royal court for me." "

Another dynasty.

Emperor Wu of the Han Dynasty, Liu Che, said in an uplifting tone: "I will see black powder in seven days!"

"Two months later, blitzkrieg Huns!"

"Kill them so badly!"

This was the case for the emperor for a time.

The morale of the generals has skyrocketed!

Huo Quzhi immediately knelt down and received the order: "The minister receives the order!

Liu Che suddenly looked up with some confusion.

Why did he say the word "blitzkrieg"?

But it feels very appropriate to put it here.

Then he stared at the light curtain and commented: "It is said that taking history as a mirror, I can be regarded as summing up experience from later dynasties today. "

"The extent of corruption within the Qing Dynasty can be seen. "

"Even the military budget dares to be greedy for ink. "

"Cannonball fake!"

"It's ridiculous. "

"I have never seen such a dynasty in ancient and modern times. "

"What kind of scene will it be when the enemy comes?"

Liu Che's scalp was numb just thinking about it.

Shu.

Liu Chan rubbed his ass.

I was so excited just now that I actually fell out of my seat.

However, this did not affect his excitement in the slightest.

Liu Chan shouted loudly: "Father, the formula!

"The old minister is remembering. Zhuge Liang responded casually, and then wrote down all the popular science content word for word. (If you read a violent novel, go to Feilu Novel Network!)

Song dynasty.

Zhao Kuangyin smiled.

During the Song Dynasty, firearms developed rapidly!

Is it completely possible to rely on firearms to defend against foreign enemies and not be disturbed by them?

"Good!"

"Come on, the gunpowder formula will be changed according to the light curtain. "

"Also, make the assault gun mentioned above as soon as possible. "

Yuan.

Kublai Khan was somewhat autistic.

The content of popular science does not have the Yuan Dynasty that he single-handedly established?

Instead, it focuses on the Song Dynasty before the Yuan Dynasty and the Ming Dynasty after the Yuan Dynasty.

What's wrong?

Isn't he worthy of the Yuan Dynasty?

But he was soon relieved.

Fortunately, there was an even worse Qing Dynasty.

In such a comparison, the Yuan Dynasty seems to be okay.

Ming dynasty. []

Zhu Yuanzhang just beat Zhu Tan fatly.

Now, apparently, it hasn't completely deflated.

He was very happy to see the development of firearms during the Ming Dynasty.

You can see the Qing Dynasty after the Ming Dynasty.

His face was horribly dark.

"How could our Ming Dynasty get into the hands of such a group of grassland people. "

"What is the difference between them and the Yuan Dynasty!"

"Ahh!!h

"It's all to blame for the descendants of future generations!"

"Shame on us!"

Zhu Yuanzhang almost went completely crazy.

It was not easy for him to end the end of China's domination by the grassland people.

In later generations, it was snatched back by the prairie people again!

He turned his head to look at Zhu Biao, his face was so gloomy that he was about to drip water.

Zhu Biao was so frightened that he took two steps back.

He immediately snatched the paper in Li Shanchang's hand, and (Nuo Nuo Hao) recorded the content of popular science.

Then, very quickly complete the diversion of the troubled waters.

Zhu Biao raised the paper in his hand and shouted: "Father!"

"You take a look at this paragraph. "

Zhu Yuanzhang looked puzzled, and then came to Zhu Biao.

Zhu Biao pointed to a record and read it worriedly: "Zhu Di, the king of Yan (that is, the later Ming Chengzu) and the Jianwen Emperor Zhu Yunwen fought in the Baigou River, and they used the "swarm of bees" shop. "

"Father, look. "

"It said that the fourth brother became the ancestor of Ming Cheng. "

"Also, it was not Xiong Ying who became the emperor, but Yun Wei. "

！！！

？？？

Zhu Yuanzhang, father and son, opened their eyes wide at the same time!
