Sun Huan patted Ying Zheng's little head.
This kid really knew how to add scenes to himself.
The reason why Sun Huan asked him to do these things was actually very simple.
It was just that no one had cleaned the City Lord's Mansion for a long time.
Sun Huan was just too lazy to make a move.
However, since Ying Zheng had said so himself…
Sun Huan could only pretend to be profound and nod.
"Your comprehension is not bad. Come with me. I'll teach you how to make salt.”
Ying Zheng said proudly.
As expected, Master was teaching him this.
Fortunately, he had comprehended it.
Master's painstaking efforts were not in vain.
Master was indeed amazing!
She had thought of teaching him this from the beginning.
Ying Zheng was convinced.
"Master, wait for me!"
Sun Huan led Ying Zheng to his laboratory.
This laboratory was Sun Cheng's top secret place.
Sun Huan was the only one who could enter and exit.
It was in a very hidden small house in the City Lord's Mansion.
Sun Huan usually spent his free time in the laboratory, slowly verifying the knowledge he had learned before.
Otherwise, they wouldn't have been able to make steam engines and refined salt.
Ying Zheng followed behind.
Just like a curious baby.
It opened up a whole new world!
" So many crystals!"
"This isn't crystal, this is glass. The crystals you saw in the inn are also made of glass. They can be made by heating them with high-temperature quartzite.”
Sun Huan paused for a moment, looking at Ying Zheng who was frantically taking notes, then continued,""The production of this thing in Sun City is also very high. It can also be made into various craft products.”
Ying Zheng did not care whether he understood or not, he nodded repeatedly.
Yes, yes!
There was more!
"What is this?"
"This is gunpowder! If you light it with fire, it will explode!"
"Explosion? What is an explosion?"
"You'll know when I set off fireworks for you tonight. Alright, stop asking questions. Watch and learn!”
Sun Huan took out a rock sized mineral salt.
He took out a basin of clear water.
Dissolve the mineral salt in clear water.
Then, he lit the alcohol lamp and heated it to boil.
"I forgot to tell you, this is also a type of chemistry.”
"Our world is made up of all kinds of substances. Each substance has its own unique properties and functions.”
"For example, this water is actually made up of water molecules.”
"Water molecules? Where is it?"
Ying Zheng was like a slacker.
The water that he drank every day was made up of water molecules?
Unheard of!
Chemistry was indeed profound!
Sun Huan continued," Water molecules are tiny particles that we can't see with our naked eyes. We need to magnify the water many times to see it. I've seen it once before, but don't even think about it.”
Ying Zheng was completely dumbfounded.
Could it only be seen after being magnified many times?
Master had seen it before?
Could it be that Master wasn't from here in the past and came from another place?
Ying Zheng instantly figured it out.
This would explain the origins of potatoes, sweet potatoes, steam engines, linen paper…
Master must have come from a mysterious place!
And these things were all brought over from there.
Sun Huan knocked on Ying Zheng's head.
"Don't be distracted in class!"
"I'll only do one side. It's up to you whether you can learn it or not!”
Sun Huan first filtered the boiling water through a fine net.
It could be clearly seen that there were many undissolved impurities left on the fine net.
However, the reason why coarse salt could not be processed into refined salt was not because of these impurities.
There were also many metal ions dissolved in the bittern.
Sun Huan could easily swap them out using the metal's liveliness.
He boiled the crude salt solution again and added a small amount of the solution of the soda.
It was soda water.
At this time, the calcium and calcium ions in the solution reacted with the carbolic acid, forming the precipitations of calcium and calcium.
After filtering it again, some residue could be obtained.
These were all junior high school chemistry knowledge.
Sun Huan's operation was basically smooth.
But in Ying Zheng's eyes, it was different.
After the coarse salt was boiled in water, there was still something that had not melted.
After filtering it, he boiled it again.
After adding a few drops of liquid, an unknown residue appeared again.
Ying Zheng was a super slacker who had no foundation in any subject.
The first thing that came to his mind was…
Creation out of thin air?
Wasn't this the method of immortals?
After Sun Huan filtered the solution again, the impurities were almost removed.
Then, he boiled the water over a large fire to evaporate it.
Very soon, Ying Zheng saw salt as thin as white sand appearing on the ground of the bottle.
This time, he was really speechless.
This was how salt was made!
In the future, no one would dare to say that they were immortals in front of Ying Zheng.
Ying Zheng wanted to throw the salt on his face.
"Today, I have the honor of witnessing the immortal technique with my own eyes. It's really my honor!”
Ying Zheng sighed.
He was probably the first person in history to be so close to an immortal.
Moreover, it was the land of immortals.
Although Ying Zheng was the Human Emperor, immortals were different.
To be an Immortal's disciple.
Embarrassing?
It was not embarrassing!
He even felt a little proud.
Ying Zheng recorded everything he saw today.
"To make refined salt, immortals pass down a technique. Boil it with water, add a little immortal liquid, and then boil it dry.”
As for what the immortal liquid was…
Ying Zheng did not know.
In any case, it was something very powerful!
Sun Huan looked at Ying Zheng's notebook and immediately felt a headache coming on.
This student was going to anger him to death!
It wasn't easy for him to learn about science.
However, he didn't expect that he would lose everything.
The technology was too advanced, and it scared the ancients.
Not to mention a child with a rich imagination.
"How many times have I told you? This is science, not some immortal technique!”
"There are no immortals in this world, and I'm not a creation out of thin air. All substances will not disappear or appear out of thin air.”
Ying Zheng nodded, pretending to be smart.
"Science, that's right. From now on, there will be no immortals, only science!”
Sun Huan suddenly felt a faint sadness.
This child had obviously changed the word 'god' into 'science'.
He didn't understand at all!
Forget it, forget it.
Teaching disciples was really difficult.
The master led the way, but the cultivation depended on the individual.
In any case, he would naturally know when he knew more in the future.
Ying Zheng turned his head and looked at Sun Huan's eyes, which were filled with admiration.
Previously, Ying Zheng was still a little unconvinced that Sun Huan was his teacher.
Now, he was truly convinced.
Not only that.
Ying Zheng felt how lucky he was.
Looking at Sun Huan, Ying Zheng gave him a deep bow.
"Master!"
"Master taught me immortal…science. I am extremely grateful. In the future, when I become a dragon among men, I will repay you.”
Sun Huan was completely speechless.
sigh ~
Playing the lute to a cow!
This misunderstanding could not be explained clearly.
Ying Zheng did not listen at all.
He didn't look smart at all.
He looked at Sun Huan as if he was looking at a panda.
