After taking full advantage of Shen Luoyan, Yun Zheng finally got up refreshed.
Shen Luoyan's face turned red with shame. She curled up in bed and refused to get up, intending to wait until her composure returned to normal before getting up.
If she went out now, Ye Zi and the others would see her expression and laugh at her.
Yun Zheng finished washing up with the help of Xin Sheng, and when he walked out, it was just dawn outside.
Winter has already begun in Shuobei, and now it gets light late and gets dark early.
After a while, the daytime hours will be even shorter, only five or six hours.
Yun Zheng was just about to go to the yard to stretch his muscles, but he saw several servants sweeping the walls of the house with brooms.
"What are they doing?"
Yun Zheng looked at Xin Sheng with a puzzled expression.
There's no snow coming into the house!
...
...
What are they doing sweeping the wall?
"They were cleaning the whitewash off the walls."
Xin Sheng replied, "The house has been a bit damp recently, and there is a lot of white dust on the wall. We just swept it a few days ago, and a lot of it has grown back. Madam Zi instructed everyone to remove the white dust on the wall this morning..."
Xin Sheng was still talking incessantly, but Yun Zheng's heart suddenly skipped a beat.
White ash?
Why is there white lime growing on this wall out of nowhere?
This is not white ash at all!
This is nitrate!
Nitrate!
The key material for making gunpowder!
"Stop! Stop everything!"
Yun Zheng was extremely excited and quickly stopped all the servants.
Everyone stopped and looked at Yun Zheng blankly, feeling inexplicably uneasy, fearing that the Sixth Prince had called a halt because he thought they had done something wrong.
"Your Highness, what's wrong?"
Xin Sheng asked blankly.
Yun Zheng did not answer Xin Sheng's question and quickly ran to the wall.
Under the puzzled gazes of everyone, Yun Zheng scraped a little white ash from the wall, put it to the tip of his nose and sniffed it gently, then poked it a few times with his fingers to confirm that it was saltpeter.
In my previous life, this kind of saltpeter would often precipitate on the walls of my hometown.
This stuff will burn even without adding sulfur, just mixing it with charcoal!
He used to scrape this thing off to play with when he was a kid.
Damn it!
No wonder he hadn’t discovered saltpeter before!
It turned out that before he got up, the servants in his house had already cleaned up the grown saltpeter.
Fortunately, I got up early today, otherwise, I wouldn’t be able to see this thing!
"Scrape off all the white lime on the wall and put it in a clean wooden barrel! Remember, only scrape off the white lime, don't scrape the wall lime in! Pick up all the clean white lime on the ground and put it away!"
Yun Zheng gave an order and immediately ran hurriedly to Zhang Xu's room.
At this moment, Zhang Xu was still sleeping soundly in the room.
“Boom boom boom…”
Zhang Xu was awakened by a rapid knock on the door.
"Who is it? Are you bored because you've had too much to eat? If you knock again, I'll chop off your hands!"
Zhang Xu was particularly grumpy when he woke up and started yelling at the outside of the house.
"Open the door! I have something urgent to discuss with you!"
Yun Zheng's anxious voice came from outside the door.
The Sixth Prince?
Zhang Xu's heart skipped a beat, and his bad mood instantly disappeared. He just put on a piece of clothing and got up to open the door.
"Sixth Prince, what's the hurry?"
Zhang Xu looked at Yun Zheng in confusion.
Seeing that his clothes were disheveled, Yun Zheng immediately said, "Hurry up and put on your clothes and follow me!"
As he spoke, Yun Zheng saw the charcoal basin in Zhang Xu's room again, and immediately took out two pieces of charcoal from it.
Zhang Xu looked at Yun Zheng in astonishment.
He knocked on his door in a hurry, 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.
Chen Luoyan didn't even have time to comb her hair before she ran out with a mess of hair.
"What are you doing so mad so early in the morning?"
Chen Luoyan looked at Yun Zheng with annoyance.
"You all step back first!"
Yun Zheng waved to the servants outside.
After all the servants had left, Yun Zheng mixed some carbon powder and saltpeter together.
He was just giving a demonstration to Shen Luoyan and the others, so he didn't care about the proportions, just mixed them together randomly.
"What are you doing?"
Shen Luoyan frowned and said, "For no reason, you got your hands dirty..."
Yun Zheng blinked and said teasingly: "Kiss me and I will tell you!"
"Pooh!"
Shen Luoyan blushed and spat lightly, saying unhappily: "Don't talk nonsense, you are so old and you have no shame!"
"shame?"
Yun Zheng curled his lips, "How much does shame cost per pound? Can it be eaten as food?"
Upon hearing this, Chen Luoyan couldn't help but glare at Yun Zheng with shame and anger.
She now understood that talking about shame to Yun Zheng was like talking to a cow!
"Okay, stop talking nonsense!"
Ye Zi looked at Yun Zheng helplessly, "What on earth are you trying to do by making such a scene so early in the morning?"
Yun Zheng raised the corner of his mouth and said in a pretentious manner: "Next, it's time to witness a miracle!"
Everyone disagreed and rolled their eyes at him.
Yun Zheng smiled, took out a piece of red-hot charcoal from the stove next to him and threw it into the mixture of saltpeter and charcoal.
“Squeak…”
In an instant, the mixture burned violently, creating a scene of fireworks.
Everyone looked at the scene in disbelief, shocked and curious.
It is normal for charcoal powder to burn.
But how could it burn like this?
“So beautiful!”
Ye Zi was the first to come back to her senses and was amazed by the fireworks in front of her. .
pretty?
Yun Zheng looked at Ye Zi with a dark face.
It’s indeed a woman!
The first thing that comes to mind is whether it looks good or not.
"This thing is very useful! I'll tell you its specific uses later!"
Yun Zheng smiled at the others and said to Zhang Xu, "From today on, you must immediately purchase a large amount of this white ash on the wall. Remember, it must be the kind that I ask people to collect. Don't be fooled by others with other things! If you really can't tell the difference, just try the method I just used and you will know!"
"good!"
Zhang Xu nodded and asked, "At what price?"
"One tael of silver for one pound!"
Yun Zheng replied.
"What?"
Hearing Yun Zheng's words, everyone was shocked.
For such a thing, he actually wanted to buy it at such a high price?
"You really have too much money to burn, don't you?"
Ye Zi looked at Yun Zheng speechlessly.
How could he waste money like this!
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 just afraid of not being able to spend it!"
This stuff looks like a lot, but it's actually not that heavy.
He didn't know where the saltpeter mines were now, so he could only collect the saltpeter first.
As for sulfur, it is easy to purchase.
People in the Dagan Dynasty also used sulfur to drive away snakes, insects, rats and ants, and sulfur could be bought in major pharmacies.
It is unrealistic to produce large quantities of gunpowder without saltpeter and sulfur mines.
Moreover, even if it is developed, it will definitely not be able to compare with the power of modern gunpowder.
However, it is still okay to keep a small amount as a backup!
Even if the power is not too great, even if only a noise is heard, at least it can scare the enemy's horses!
Just do it now, it will come in handy sooner or later!
"Okay, then I'll hurry up and buy it!"
Zhang Xu nodded and pulled Yun Zheng aside. "One hundred war horses are indeed not enough. That person said that he can only buy twenty war horses at most. If we really want them, he can sell them to us at twenty gold per horse..."
This is that person's bottom line.
All this gold and silver did not fall into his pocket alone.
He also had to take out gold and silver to bribe people.
Otherwise, losing twenty war horses would be enough to cost some people their heads!
Yun Zheng thought about it and nodded, "Then buy it!"
