It is known that the recipe for gunpowder includes: sulfur, charcoal, saltpeter! Mixing these three together in a certain proportion makes gunpowder.

And the best ratio of black powder, if Jiajing remembers correctly, should be 10% sulfur, 15% charcoal, and 75% saltpeter.

"Yes, Your Majesty!"

When Yi Bin heard this, he hurriedly gathered the craftsmen who were responsible for improving the gunpowder formula, and everyone immediately came to the room where gunpowder was specially tested.

When these craftsmen learned that their immediate superiors had asked them to conduct experiments according to the emperor's ratio, their faces were full of fear, and their hands began to tremble slightly.

Soon, the three materials of sulfur, charcoal, and saltpeter were placed in front of them, and several craftsmen looked solemn.

After a while, Jiajing's voice came: "One percent sulfur, one percent charcoal, seven percent five, and seven percent five percent saltpeter!" Let's experiment according to this ratio. ”

Hearing the emperor's orders, these craftsmen did not dare to slack off, and soon began to match.

These craftsmen have long been responsible for blending and refining the recipe of gunpowder, so they have a very precise grasp of the amount of gunpowder!

They soon made gunpowder in the ratio proposed by the emperor.

Looking at the black gunpowder in front of them, the hearts of everyone present couldn't help but start to worry, if the ratio proposed by the emperor was wrong, what would happen then?

And Jiajing looked at the black powder in front of him, with a confident look, and then ordered.

"Let's start experimenting!"

"Yes, Your Majesty!"

After everyone retreated to a safe distance, a craftsman was seen taking out a fire fold from his body and immediately lighting the fuse.

When the fuse burned out, the pile of black powder was quickly ignited, emitting a burst of intense light, followed by a choking white smoke!

Jiajing took the handkerchief from Lu Fang's hand, covered his mouth and nose, looked at the white smoke, couldn't help but breathe a sigh of relief, and muttered to himself silently.

"Looks like I'm not mistaken!"

After a brief silence, the craftsmen at the scene immediately erupted in a loud cheer.

Judging from the light and heat generated when the pile of black gunpowder burned just now, His Majesty's ratio is completely correct!

This black gunpowder was dozens of times more powerful than the gunpowder they had originally experimented with!

The problem that they had been racking their brains for a long time had not been solved, but it was easily solved by His Majesty.

"Your Majesty! Your Majesty! ”

The craftsmen who were in charge of the experiment before had their faces full of fanaticism, knelt on the ground, and kept muttering.

"Your Majesty, since there is more powerful gunpowder now, the research and development of new cannons will also go more smoothly!"

I saw Yi Bin kneeling on the ground, his face full of joy.

"Since you want to increase the range of the cannon, you might as well try to lengthen the barrel, and then match it with the black powder above, the range and power of the cannon will be greatly improved!"

Jiajing immediately added.

"Yes, Your Majesty, Weichen obeys!"

Yi Bin kept Jiajing's words firmly in his heart, and secretly resolved to conduct experiments as soon as His Majesty left.

"In addition, the ratio of gunpowder must not be leaked out, and those who violate it will be killed!"

Immediately, Jiajing looked at Yi Bin who was kneeling on the ground with a very cold gaze, and warned in a deep voice.

"Your Majesty, you can rest assured, if the ratio of gunpowder leaks out, Weichen will come to see you!"

And out of the need for secrecy, Jiajing did not let everyone present talk too much about the specific ratio of gunpowder, but chose to let Yi Bin record it and keep it strictly, without permission, no one is allowed to read it.

Subsequently, after Jiajing explained some of the thoughts in his mind to Yi Bin, the official in charge of managing the Weapons Department, he and Lu Fang embarked on the journey home.

"Weichen sends your majesty, long live my emperor, long live long live!"

At this moment, Yi Bin was kneeling on the ground respectfully, looking at the back of Jiajing leaving, and couldn't help but think so.

"Your Majesty is truly brilliant and wise! He not only put forward the correct ratio of gunpowder, but also put forward many valuable suggestions for the next work of the Ordnance Division. ”

"But what did Your Majesty just say about the bomb that can be held in your hand and thrown at the enemy?"

"By the way, I remember, Your Majesty named it a grenade!"

……

Jiajing was sitting on top of the dragon chariot at the moment, looking at Lu Fang with a look of wanting to speak and stopping, and chuckled.

"Lu Fang, do you have any questions for me?"

Lu Fang saw that he was seen through by the emperor, and after hesitating for a moment, he finally chose to explain it to the emperor and Panpan.

"Yes, Your Majesty! The slave felt that you had made those suggestions as if you had seen them with your own eyes. ”

"Also, when Your Majesty proposed the ratio of gunpowder before, the slave maid also felt ......"

After listening to Lu Fang's words, Jiajing explained with a smile on his face.

"Of course I've seen these things, do you remember the book I had in my hand earlier?"

"Your Majesty, is it ......?"

When Lu Fang heard what Jiajing said, after recalling it for a long time, he reacted suddenly, and his face was full of incredulity.

"It turned out to be in the hands of His Majesty, the book full of tadpole texts!"

Lu Fang thought so in his heart.

"Well, that's right, all the things I brought up today are recorded in that book!"

"As for the ratio of gunpowder, it was also recorded in that book."

Jiajing glanced at Lu Fang casually and said slowly.

Hearing the emperor's reminder, Lu Fang gradually reacted and felt ashamed of his previous behavior.

"It turns out that Your Majesty has been studying the knowledge in that book all along!"

"And I thought that Your Majesty's plaything was demoralized, Lu Fang, Lu Fang, you really deserve to die!"

Gradually, the look of shame on Lu Fang's face disappeared, and he immediately mustered up the courage to ask Jiajing.

"Your Majesty, the slave is very curious, what is the name of that book? There's so much weird and very useful knowledge out there! ”

Jiajing took in the expression on Lu Fang's face, and joked with a smile: "The name of that book is called Science." ”

"Science?"

Lu Fang chewed on the word repeatedly, and then fell into deep thought.

After a long time, I saw that Lu Fang's eyes gradually became bright, and he asked Jiajing.

"Your Majesty, the slave maid just thought that if she could translate this book called science!"

"And then hand it over to thousands of students from my Ming Dynasty to study, and maybe, many problems will be solved."

After listening to Lu Fang's words, Jiajing was in a good mood and said loudly.

"That's a good idea! Well, it's a long-term thing, and it can't be done overnight. ”

"Therefore, this incident like today's can be publicized by the way! Get everyone interested in science. ”

"But you can't give away important secrets, you know?"

After hearing this, Lu Fang hurriedly responded respectfully.

"The slave knows!"

……

When Jiajing returned to the Heart Cultivation Palace, everything that happened today quickly spread out, attracting many officials to start discussing.

"Have you heard, Your Majesty went to the Ordnance Division today, not only did they solve a big trouble, but also put forward a lot of useful suggestions!"

"Oh, what's the big trouble?"

"I don't know, it seems to be about gunpowder!"

"It is said that Your Majesty learned this knowledge from a book called Science!"

"Science, do we have this book?"

"I don't know, that's a book that Your Majesty reads! How can it be like us? ”

"I guess this book called science must be very obscure! Only someone as intelligent as His Majesty would be able to understand the above contents. ”

"If only Your Majesty could find a time to tell us about the above content, so that everyone will be protégés of the Son of Heaven!"

"You're beautiful!"

Not only are officials in the DPRK and China talking about this, but even the cabinet is not exempt from vulgarity.

"By the way, Elder Yan Ge, you have a lot of books in your house, do you have a book called science?"

Xu Jie put aside the brush that was reading the sparseness, and then asked Yan Song.

"Science?"

After listening to Xu Jie's words, Yan Song immediately fell into deep thought.

Immediately, Yan Song began to recall in his mind whether there was a book called science among the books he had read.

After a long time, I saw Yan Song shake his head and respond: "It doesn't seem to be." ”

After getting a definite answer from Yan Song, Xu Jie did not hide the disappointment on his face, and said slowly: "Alas, this is really a pity! ”

In fact, even if there is this book, Yan Song will not say it!

He had already made up his mind that when his duty was over for the day, he would go home and look carefully to see if there was any book at home.

After all, this is also to have more common topics with His Majesty, and what an honor it is to read the same book with His Majesty!

And the others also had the same idea as Yan Song, and they all decided that after they went back today, they would turn out all the books in the house and see if there was a book called science in it.
