Chapter 115 Consider You Rich
"When saltpeter dissolves in water, it absorbs a large amount of heat, causing the surrounding water temperature to drop sharply, thus forming ice." Mu Wanwan explained patiently.
Making ice from saltpeter is not a difficult task. The shadow guards followed Mu Wanwan's instructions step by step.
First add saltpeter into the large barrel, add water into the small basin, and place the small basin in the center of the large barrel.
Then everyone watched intently from the side. It wasn't long before the saltpeter took effect. Frost began to form on the edge of the small basin, gradually spreading to the center, forming a thin layer of ice.
"Mistress, look, it's turned into ice!" Ying Er shouted excitedly.
It's like magic, it's amazing.
Si Yuan didn't expect that making ice was so simple. What about those ice cubes that he bought at a high price before?
[Mu Wanwan: Consider you rich]
You know, even the concubines in the palace were given a fixed amount of ice every day.
Although there were dedicated people in the palace to take charge of storage matters, the manpower and material resources consumed were enormous.
The amount of ice that survives the hot summer heat without melting is pitifully small.
It turned out that Wanwan could make it so easily.
"By evening, this basin of water should be able to freeze into thick ice." Mu Wanwan said, "Ying Er, spread this ice-making method in the name of the Prince's Mansion."
Mu Wanwan didn't intend to hide it. Now that the situation has been determined, the people of Ruilan will also be Si Yuan and her people in the future. It is the common responsibility of her and Si Yuan to make the people live a better life.
Si Yuan felt a warm feeling in his heart and he embraced Mu Wanwan in his arms. This was his Wanwan.
If this ice-making technique is applied to the people, it will definitely relieve the summer heat and improve people's quality of life.
There are also those soldiers. In the past, soldiers were prone to heatstroke when fighting or training in high temperature environments.
If a large amount of ice is placed in the tent, the soldiers will have a cool space to rest.
Food is also difficult to store in summer. People have learned how to make ice, which allows them to preserve more food and reduce waste.
"The purchase of saltpeter must be registered by a dedicated person, and the quantity cannot be too large," Mu Wanwan added.
Si Yuan was a little confused, "Why limit the purchase quantity?"
"Saltpeter can not only be used to make ice, but it's also an important raw material for making gunpowder. If someone deliberately hoards it and uses it to make gunpowder, it would be more trouble than it's worth."
Mu Wanwan remembered the classic formula of gunpowder, 'one sulfur, two nitrates, and three charcoal' very clearly.
Although people of this era did not know about black powder, what if someone happened to discover it?
In the history that I learned in my previous life, there were many alchemists who claimed that they could make people immortal.
Don’t the pills they refine contain saltpeter and sulfur?
This is why the furnace often exploded. If there were such so-called alchemists in this dynasty, they would have discovered the gunpowder component.
I know a lot about Huoyao Siyuan, and I didn't watch those videos on his phone in vain.
The high-tech weapons Wanwan gave me are strictly controlled.
However, if the method of making gunpowder falls into the hands of people with ulterior motives, the consequences will be unimaginable.
Si Yuan explained the matter seriously to Ying Er and the others, making sure that nothing would go wrong in the process of selling saltpeter.
Ying Er and others took the order and left.
"Don't worry, as long as you control the amount, there will be no problem." Mu Wanwan said.
Even if we know the approximate proportions, there are no precise measuring tools in this era, so it is difficult to accurately control the proportions of the three.
Moreover, the production process of black powder is extremely dangerous, and there is a risk of explosion from the moment the raw materials are mixed.
Especially when grinding, even the slightest friction may cause an explosion, and before anyone else can finish making it, you may be killed by the explosion.

"Crown Prince, Crown Princess. Master Mu and Master Ouyang are here." The butler reported at the door.
Si Yuan was handling official business in the front hall, while Mu Wanwan was watching popular short dramas on her phone.
This short drama is really addictive. Mu Wanwan said she also wants to act in an episode.
"Let them in." Si Yuan said.
"Why is the door to the front hall closed in broad daylight?" The moment Mu Yuheng pushed open the door, the cool air made him and Ouyang Moyu shiver.
Ouyang Moyu was curious about why the room was so cool.
He had never studied his phone carefully except when Mu Yuheng pestered him to play games.
Of course I don’t know what air conditioning is.
Just yesterday, Ouyang Moyu was busy dealing with military affairs. Mu Yuheng contacted him to play games, but he didn't reply.
As a result, Mu Yuheng was chased and scolded by nine people in the game! This morning, he drove his mecha to the northern border to pick up Ouyang Moyu.
The people in the game asked him to play 5V5, but they didn't have enough manpower, so they came to Si Yuan's house to find them to fill the gap.
However, Ouyang Moyu has no interest in games at the moment. What he is curious about is what new gadget Mu Wanwan has come up with that can make the room cool and pleasant in this summer.
"Sister, please install a few air conditioners in the Prime Minister's Mansion." Mu Yuheng is an old hand at using mobile phones, and he has also enjoyed the air conditioners in the space.
Of course I know the source of this cool air.
"I've prepared them for you, your parents, and Chaochao a long time ago. I'll bring them back to you later. I'll install the video and send it to your phone." Mu Wanwan laughed and looked at Ouyang Moyu who was curious at the side. "Military Advisor, bring two back too."
Ouyang Moyu's eyes lit up and he thanked Mu Wanwan. This trip back to Beijing was not in vain, as his wife had given him good things again.
"Mo Yu, why did you suddenly come back to Beijing?" At this time, Si Yuan had finished the work in his hands, put down his pen and looked over.
Ouyang Moyu glanced at Mu Yuheng and said, "I've been idle in the Northern Territory recently, so I came back to take a look."
He would only act like a fool with Mu Yuheng because Meng Yi was in the northern border.
Si Yuan saw through it but didn't say anything, as he also wanted to promote the ice-making method in the army.
Now that Ouyang Moyu is here, he doesn't have to send a message. It would be clearer to discuss the control of saltpeter in person.
"It just so happens that I have something to tell you. Please come with me." Si Yuan stood up and led Ouyang Moyu to the yard.
In the yard, a thick layer of ice had formed in the small basin. Mu Wanwan put more saltpeter, so the ice formed quickly.
Looking at the basin full of ice, Si Yuan explained calmly, "The key to making ice lies in saltpeter."
Si Yuan explained the method of making ice from saltpeter and also explained the importance of saltpeter control.
When he returned to the front hall, Ouyang Moyu had not yet recovered from the novel ice-making technique. He did not expect that ordinary saltpeter could not only be used to make ice, but could also be used to make gunpowder.
Mu Yuheng was not very interested in the method of making ice, because Mo Yu would tell him anyway.
