"Your Majesty, I found that the gunpowder in the arsenal seems to be more powerful after it is wet and then dried again. I have never thought of the reason behind this, so I specifically asked your Majesty for advice!" Ge Hong said.
When Liu Yu heard this, he immediately became energetic.
Ge Hong is a great and powerful man whose name has been recorded in history. If you just want to force him into an official position, you would be looking down on this man who meant to refine elixirs and practice Taoism.
After Liu Yu summoned Ge Hong, he quickly shocked Ge Hong with a series of chemical knowledge.
Ge Hong, who was shocked at the time, once thought that the current emperor was also a fellow Taoist and was extremely obsessed with Taoist cultivation.
However, after Liu Yu whetted his appetite, he got him to work as an errand in the Department of Salt, Iron and Military Preparation.
For a period of time, whenever Ge Hong encountered some difficult questions, Liu Yu could always give him answers from an angle that surprised him.
In this way, Ge Hong admired and worshiped Liu Yu even more.
Every time Liu Yu answered questions, he gained a further win over Ge Hong.
"These gunpowders are originally made by mixing three kinds of chemicals. However, no matter how you stir them, the three powders always do not blend well with each other. If it encounters moisture, part of the fire salt inside will dissolve into the charcoal and sulfur. .”
Liu Yu began to answer patiently.
Ge Hong listened very carefully and saw Liu Yu continue to speak.
"When the gunpowder becomes moist, it will fuse more closely. After it is dried again, the gunpowder will naturally explode more quickly and fully, which means it will naturally be more powerful!"
The chemistry knowledge that Liu Yu once mastered has begun to slowly fade away as time goes by.
Therefore, after getting Ge Hong, a good student with a thirst for knowledge, it can be said that he wanted to teach him everything he could.
In order to better subdue Ge Hong and prevent him from running away from the world after learning, Liu Yu wished he could write a textbook for him.
"Oh, that's it. Your Majesty is indeed a god who came to this world, and he knows everything!" Ge Hong admired from the bottom of his heart.
"Nothing in the world has rules to follow. Not only this gunpowder, but also all other material changes have rules to follow!"
As Liu Yu spoke, he took out a brand new book from his arms.
"Your Majesty, what is this?" Ge Hong took it and asked in confusion.
"The secret of the method of all things in the world that I just mentioned is hidden in this book. If you can learn it thoroughly, you can create things out of thin air and turn stone into gold!"
Liu Yu said in an exaggerated tone.
"What? Your Majesty said it, but is it true?" When Ge Hong heard this, he was immediately overjoyed.
He has been practicing Taoism for nearly twenty years. He is not just pursuing the way to immortality, but also wants to understand the way of change in the world.
However, with that kind of simple hard thinking, even if you want to break the sky, you can't come up with anything.
Now that Liu Yu had answered his questions many times, Ge Hong was already convinced of Liu Yu's level of 'cultivation'.
Now that Liu Yu personally gave him the treasure book, he was even more happy.
Ge Hong couldn't wait to open the book.
However, after just reading the first three sentences, I was completely fooled.
"Hydrogen, helium, lithium, beryllium, carbon, nitrogen, oxygen, fluorine, neon, sodium, magnesium, aluminum, silicon, phosphorus,,,,"
"Oxysilica aluminum iron calcium sodium potassium,,,"
Because the characters here seem familiar, but I don’t even recognize them, let alone what they mean.
"Your Majesty, what are these words? I am so stupid that I don't understand them at all."
Ge Hong said to Liu Yu with a sad face.
Liu Yu patted his shoulder and comforted Ge Hong.
"Don't be anxious. This book of mine can be said to have been learned by all living beings from all the great masters in the world. It cannot be understood so quickly."
"Even if there are words you don't understand, don't worry. There are explanations at the end. With your intelligence, you will definitely be able to understand."
"If you really don't understand something, just write it down and ask me again."
For his "good student" Ge Hong, Liu Yu could say that he wanted to give him everything he could.
This knowledge is more useful to Liu Yu than conquering cities and territories.
However, in this day and age, it is difficult for Liu Yu to even find someone who understands the crudest meaning.
What's more, the vast majority of people today are illiterate, and it is even rarer to find interested people among a group of literate people from high families and poor families.
The most reliable person now is Ge Hong.
"Your Majesty, I understand. I will treasure it and study this book carefully to repay Your Majesty's favor!"
The more Ge Hong couldn't understand the book, the more profound he felt the book contained.
Otherwise, if he could see it clearly at a glance, it would definitely be a lie.
"Treasure? No, no, no, I don't mean that." Liu Yu shook his head and said.
"Ah? Then I will return it to Your Majesty immediately after reading it!?" Ge Hong said with some reluctance.
"Hahaha, you misunderstood, and that's not what I meant. What I mean is that if you want to study this book first, if you don't understand anything, you can ask me. Once you understand it thoroughly, you can explain it to me. Recruit smart people to carry forward this knowledge and make it even better!" Liu Yu said.
In fact, this book written by Liu Yu is an introductory material for basic chemistry.
Some basic common elements are summarized, along with some common responses.
For the knowledge of chemistry, it is just a shabby stepping stone.
However, even such a simple stepping stone must be verified and promoted by elites like Ge Hong.
After all, Liu Yu was the emperor, so he couldn't abandon military and political affairs and lead a group of chemists to conduct crazy experiments every day.
"Your Majesty, do you want to make this kind of sky-stealing technique public?" Ge Hong was so surprised that he could hardly close his mouth.
In his view, every sect's monastic skills are absolute secrets, and they are often kept secret.
But what Liu Yu meant was that he should learn it himself first and then teach it to more students.
And it seems that the more people you teach, the better.
"Well, yes, that's what I mean. The road reaches the sky and the sky is huge, but there will never be room for others just because one person knows the secrets and reaches the top."
Liu Yu said, took out another scroll, and then said to Ge Hong.
"There are so many mysteries in this world that one person can never fully understand or study them all. There must be more people to build the tower of this knowledge higher and higher. Knowing You can touch the real sky!" Liu Yu said.
