Having taken advantage of Shen Luoyan, Yun Zheng finally got up feeling refreshed.
Shen Luoyan's face turned red with embarrassment, and she stayed in bed and refused to get up, planning to wait until her expression returned to normal before getting up.
If she goes out now, if Ye Zi and the others see her face, they will laugh at her.
Yun Zheng finished washing up under Xin Sheng's care. When he walked out, it was just getting dark outside.
Winter has begun in Shuobei, and now it gets bright later and gets darker earlier.
After a while, the days will be shorter, only five or six hours.
Yun Zheng was about to go to the yard to stretch his muscles when he saw several servants sweeping brooms on the walls of the house.
"What are they doing?"
Yun Zheng looked at Xin Sheng with an incomprehensible expression.
There's no snow drifting into this house!
What were they scanning the walls for?
"They were cleaning the white dust off the walls."
Xin Sheng replied: "The room has been a little humid recently. There is a lot of white dust on the wall. It was just swept a few days ago and a lot of it has grown again. Madam Zi gave an order yesterday to let everyone remove the white dust on the wall this morning. Divide by one…”
Xin Sheng was still talking nonstop, but Yun Zheng's heart suddenly jumped.
White ash?
So good, why is there white dust growing on this wall?
How the hell is this white ash!
This is saltpeter!
Nitrate!
The key material for making gunpowder!
"Stop! Stop everyone!"
Yun Zheng was so excited that he quickly stopped all the servants.
Everyone stopped one after another and looked at Yun Zheng with blank expressions, feeling inexplicably uneasy in their hearts, fearing that the Sixth Prince would stop because he thought they had not done a good job.
"Your Highness, what's wrong?"
Xin Sheng asked blankly.
Yunzheng didn't answer Xin Sheng's question and hurried to the wall.
Under everyone's doubtful gazes, Yun Zheng scraped a little bit of white ash from the wall, put it to the tip of his nose and smelled it, then poked it a few times with his fingers to confirm that it was saltpeter.
In my previous life, this kind of wall salt often precipitated on the walls of my hometown.
Even if no sulfur is added to this thing, it can burn just when mixed with charcoal!
When he was a kid, he used to scratch this thing a lot to play with.
Damn it!
No wonder he hadn't discovered saltpeter before!
Before I even got up, the servants at home had already cleaned up the saltpeter that had grown on my bed.
Fortunately, I got up early today, otherwise, I wouldn’t even be able to see this thing!
"Scrape off all the white ash on the wall and make a clean wooden bucket to store it! Remember, only scrape the white ash off, don't scrape the wall ash in! Get all the clean white ash on the ground and put it in it! "
Yunzheng gave an order and immediately hurried to Zhang Xu's room.
At this moment, Zhang Xu was still sleeping soundly in the room.
"Dong dong dong..."
Zhang Xu was awakened by a rapid knock on the door.
"Who is it? You are so full after eating, aren't you? If you knock again, I will chop off your hands!"
Zhang Xu was extremely angry when he got up, and he roared outside the room.
"Your uncle, open the door quickly! I have something urgent to ask you!"
Yun Zheng's anxious voice came from outside the door.
Your Highness Sixth?
Zhang Xu's heart skipped a beat, and most of his anger disappeared in an instant. He approved a random piece of clothing and quickly got up and opened the door.
"Your Highness, why is it so urgent?"
Zhang Xu looked at Yunzheng confused.
Seeing that his clothes were disheveled, Yun Zheng immediately said: "Put your clothes on quickly and come with me!"
While talking, Yunzheng saw the charcoal basin in Zhang Xu's room again, and immediately took out two pieces of charcoal from the charcoal basin.
Zhang Xu looked at Yun Zheng in astonishment.
He hurriedly knocked on his door, just to get two pieces of charcoal?
When Zhang Xu put on his clothes and came outside with Yun Zheng, everyone in the mansion was alarmed.
Shen Luoyan didn't even have time to comb her hair, so she ran out with her messy hair.
"Why are you so crazy so early in the morning?"
Shen Luoyan looked at Yunzheng angrily.
"You all stand down first!"
Yun Zheng waved to the servant outside.
After all the servants retreated, Yun Zheng mixed some carbon powder with wall salt.
He is just giving a demonstration to Shen Luoyan and the others. He doesn't pay attention to the proportions, just mix them together randomly.
"What are you doing?"
Shen Luoyan frowned and said, "You're so good, but your hands are dirty..."
Yun Zheng blinked and said teasingly: "Kiss me and I'll tell you!"
"Pooh!"
Shen Luoyan blushed and spat lightly, and said angrily: "Don't talk nonsense, such a big man has no shame!"
"shame?"
Yun Zheng curled his lips, "How much does a pound of shame cost? Can it be used as food?"
When Shen Luoyan heard this, he couldn't help but glared at Yunzheng shyly.
She now understands that telling Yun Zheng that she is ashamed is just playing the piano to a cow!
"Okay, stop talking nonsense!"
Ye Zi looked at Yunzheng helplessly, "What are you going to do by making such a fuss so early in the morning?"
Yun Zheng raised the corner of his mouth and said in a pretentious manner: "The next step is to witness the miracle!"
Everyone was disapproving and rolled their eyes at him.
Yunzheng smiled, took a piece of red-hot charcoal from the stove nearby and threw it into the mixture of saltpeter and charcoal.
"呲呲......"
In an instant, the mixture burned violently, creating a scene of fiery trees and silver flowers.
Everyone looked at the scene in front of them in disbelief, shocked and curious.
Charcoal powder burns normally.
But how could it burn like this?
"so beautiful!"
Ye Zi was the first to come to his senses and marveled at the fireworks in front of him. .
pretty?
Yun Zheng looked at Ye Zi with a dark expression on his face.
It is indeed a woman!
The first thing that comes to mind is whether it looks good or not.
"This thing is very useful! I will tell you the specific use later!"
Yun Zheng looked at a few people with a smile, and then said to Zhang Xu: "From today on, you immediately buy a large amount of this kind of white dust on the wall. Remember, it must be the kind I asked people to collect. Don't let others take other things." It’s a lie! If you really can’t tell the difference, just try the method I just did and you’ll know!”
"good!"
Zhang Xu nodded and asked: "At what price should I buy it?"
"One tael of silver per catty!"
Yun Zheng replied.
"What?"
Everyone was shocked when they heard Yun Zheng's words.
He actually wants to buy such a thing at such a high price?
"Are you really overwhelmed with money?"
Ye Zi looked at Yunzheng speechlessly.
How could he waste money so much!
No matter how much money you have, you can't waste it like this!
"This thing is very useful!"
Yun Zheng shook his head and said: "I'm not afraid of spending money, I'm afraid that I won't be able to spend any money I have!"
This thing looks like a lot, but it’s actually not that overwhelming.
He doesn't know where there are saltpeter mines now, so he can only collect the wall saltpeter first.
As for sulfur, it is easy to purchase.
People in the Daqian Dynasty also used sulfur to drive away snakes, insects, rats, and ants. Sulfur can be purchased in major drug stores.
Without saltpeter ore and sulfur ore, it would be unrealistic to produce large amounts of gunpowder.
Moreover, even if it were produced, it would certainly not be as powerful as modern gunpowder.
However, it’s still okay to get a small amount for backup!
Even if the power is not too great, even if it only makes a sound, it can still scare the enemy's horses!
Anyway, let’s do it first, sooner or later it will come in handy!
"Okay, then I'll hurry up and buy it!"
Zhang Xu nodded and pulled Yun Zheng aside, "It's really hard to handle a hundred war horses. The man said that there are only twenty war horses at most. If we sincerely want them, we can sell them to us for twenty gold each... …”
This is that person's bottom line.
These gold and silver did not fall into his pocket alone.
He also had to take gold and silver out to do some sorting.
Otherwise, losing twenty war horses would be enough to kill some people!
Yunzheng thought for a while, nodded and said: "Then buy it!"
