Daming: I asked you to hang yourself, but I didn’t ask you to rebuild the Ming Dynasty

Zhu Youjian handed the barrel and musket to his guards, and then said:

"I wonder if any of you ever played with tops when you were young?"

Bi Maoliang nodded:

“Of course I have played with it.

Just wrap a whip around the top, pull it, and keep whipping it, and the top will spin on the ground. "

Bi Maokang also nodded:

"Your Majesty, my skills are better than my brother's. I can make the top spin at one point!"

Zhu Youjian laughed.

He was about to ask someone to bring him a gyroscope and explain its principles to them, when Bi Maokang handed him a knife.

This old man is so considerate!

"Then have you ever thought about why the top spins in one place?"

"This……"

The crowd was stunned.

Even though they are all technological giants in the world, they have never thought about this problem.

Zhu Youjian smiled.

He persuasively said:

“The development of any technology is not achieved overnight.

Understand every simple detail in life, then summarize it and give it a definition.

Then, take this definition and consider whether it can be integrated into technology.

I think this is the essence of Mohism back then. "

Bi Maoliang and the other two blinked. The Mo family has been cut off for so many years. Who knows what the Mo family was chasing back then?

never mind!

Let the emperor say whatever he wants!

As long as His Majesty gives us new drawings!

Practical technology experts never care about these falsehoods.

……

Zhang Jimeng was thoughtful.

The emperor's words seemed to be the way they should have compiled the catalog!

Zhu Youjian pointed out:

"For example, gunpowder, the essence of gunpowder is combustion.

Since it is burning, it must produce a heat wave, and this heat wave becomes the thrust that pushes the bullet forward.

So, can we define it this way - the reason why firearms can kill people is that the thrust is strong enough!

According to this idea, when the thrust is enough, it doesn't matter whether it is loaded with gunpowder or not? "

Zhu Youjian's words shocked everyone's jaws.

Yup!

If we infer from the results, the emperor's reasoning is completely correct!

Zhu Youjian waved his hand and got a royal guard in exchange.

He pointed at the man and said:

"Fu Xiaoqi's specialty is oral escort.

All it takes is a bamboo tube and a special flying needle.

He can kill people and become invisible within ten steps. "

After saying that, Zhu Youjian asked the man to perform a unique skill of blowing darts.

Jin Yiwei Xiaoqi took out the blow dart from his arms and aimed an arrow at the trees not far away.

When they saw a quivering flying needle stuck in the neem tree ten steps away, everyone believed the emperor's words.

Fu Xiaoqi picked up a neem fruit from the ground, stuffed it into a bamboo tube, then puffed up his cheeks and blew it down in one breath.

"Boom!"

The sound of neem fruit hitting the neem tree can be heard clearly.

Zhu Youjian used practical actions to prove the possibility of his speculation.

Everyone nodded, secretly pondering the emperor's intentions.

Zhu Youjian waved Fu Xiaoqi to retreat, and then said:

"Summary the situation, explain the definition, and then people can understand the truth based on the definition. This is the important task of you and other technical people!"

Bi Maokang suddenly realized it and said anxiously:

"Don't worry, Your Majesty. After I return, I will sort out the books I wrote in my early years."

Zhu Youjian smiled and nodded.

He continued:

"Okay, back to our question - is the top spinning on the ground because of the force we exert on it?"

"If the top can be stabilized at one point because of the application of force, then what is the direction of this force?"

"Ring-shaped!"

Bi Maokang was overjoyed:

"I understand, what Your Majesty means is - since a top with a circular force exerted on it can spin stably at one point.

So, when we apply a circular force to the bullet, the trajectory will be stable! "

Zhu Youjian nodded with a smile and corrected:

"I think the force on this bullet can be accurately described as - spiral force.

Because the annular shape is a circle, it can only rotate in place after applying force. In other words, a bullet with annular force applied cannot exit the barrel of the gun.

Only the spiral force, because the direction of the force is forward, can push the bullet out of the gun chamber and still maintain a stable trajectory. "

Spirals are no stranger to Akito.

As soon as Zhu Youjian said it, everyone understood.

"I know what to do!"

Bi Maoliang laughed loudly:

“As long as you find a way to make the bullet rotate, you can naturally stabilize the trajectory.

In this way, the distance at which soldiers can accurately aim and shoot will be greatly increased. "

The corners of Zhu Youjian's mouth curled up.

It’s just good to talk to smart people, it’s totally effortless!

He picked up the stone on the ground:

"But there is another question. Have the Qing family ever thought about it?"

Bi Maokang was stunned, looking at the round stone in the emperor's hand, and instantly thought of a spherical bullet.

He blurted out:

"What your Majesty means is - why can't round stones be shot in a straight line?

The long top can stand on the ground, right? "

"Exactly!"

Zhu Youjian laughed:

"Can you guys try to make a groove in the barrel of the gun, and then experiment with spherical bullets and gyro-shaped bullets respectively?"

"Put a groove in the barrel?"

With one word to wake up the dreamer, Bi Maokang instantly understood what the emperor meant.

The emperor didn't give him any drawings, but he gave him a research direction!

He laughed:

"Your Majesty, don't worry. I will definitely find a way to stabilize the ballistic trajectory within ten days!"

After saying that, he grabbed his eldest brother, not even his apprentice, turned around and ran away.

Zhang Jimeng and others smiled bitterly and saluted the emperor. After retiring, they hurriedly chased after the two masters.

The two mentors are already old, so don’t fall down!

Zhu Youjian smiled bitterly.

ten days...

motherfucker!

Ten days later, what are you going to do to fool these two people?

Ugh!

When there is no talent, I can’t sleep at night thinking about it.

After having more talents, I was so worried that I couldn’t sleep at night...

Prosecutor Zhu You sighed:

life...

As soon as Brother Bi Maokang was tricked away, Hao Yaoqi's secret message arrived.

Zhu Youjian was surprised and happy to hear that Zheng Chenggong came with nearly a thousand ships, and Hao Daguo even tricked ten bird ships.

Surprisingly, as his power gradually became more and more stable, more and more important people who were famous throughout the original history gathered under his command.

With so many great people around him, Zhu Youjian was really afraid that if he did something wrong, he would disgrace them.

Naturally, I am overjoyed that the arrival of these talented people is enough to prove that my actions have impressed these talented people.

People recognized him.

Zhu Youjian's hand holding the letter was trembling.

He forcibly suppressed his excitement and put the letter in his arms.

The more excited you are, the less able you are to make an immediate decision.

Zhu Youjian deeply understands this truth.
