Ancient natural disasters, walking sideways in the maximum level space!

Jiang Yue and Xiao Zhu really wanted to go back to their room to enjoy the cool breeze, but Concubine Liang would definitely not let them go back now.

Besides, it’s almost noon, so I must keep her for lunch. She doesn’t want to move in the middle of the day, and won’t she be too hot to eat if she eats later?

No, we have to think of a way. How can a living person be killed by holding his urine?

"Aunt, the weather is getting hotter. Didn't the palace give you some ice to cool you down?"

There was no need for Concubine Liang to explain. Her maid Yuchun bowed and said, "In reply to the princess, since the earthquake in Kyoto.

The ice stored in the palace was pressed into the cellar and could not be dug out at all.

All along the way, the masters have had to endure the high temperatures, and our queen has fainted from heatstroke several times."

Jiang Yue felt sad when she heard how much suffering Concubine Liang had endured.

After all, we have never been together, so it is normal that there is no affection.

For the sake of these new relatives, and mainly for herself and Xiao Zhu, Jiang Yue decided that she wanted to make ice!

"Aunt, I have a way to make ice. If you follow my method, you'll have an endless supply of ice to cool you down."

Seeing the disbelieving looks from the few people, Jiang Yue asked Xiao Zhu to prepare some things for her. Yao Chi was afraid that no one would listen to Xiao Zhu, so she asked Hong Mei to go along.

After a while, two men came in with a few young eunuchs.

Concubine Liang and a few others came over to watch Jiang Yue busying herself, and Xiao Zhu helped her. In fact, making ice is very simple.

Prepare two wooden basins, one large and one small, and pour an appropriate amount of water into the smaller basin, about 80%.

Slowly add the ground saltpeter powder into the water and stir constantly to mix the saltpeter and water thoroughly.

During the mixing process, monitor the water temperature with a thermometer. When the water temperature drops to around 0°C, part of the water will begin to freeze.

During the freezing process, continue stirring to allow the ice crystals to form a uniform slushie.

When ice crystals are formed, move the iron basin to a cool place and let it cool naturally to make ice cubes.

It was not convenient to take out the thermometer in public, so I could only pour in saltpeter powder slowly.

Everyone was stunned as they saw with their own eyes that the saltpeter and water turned into ice cubes.

Prince An was the first to react. He grabbed a handful and put it on his face.

"It's really ice! Mother, Third Brother. My cousin really made ice! Oh my god! Come and touch it."

The remaining few people woke up as if from a dream, and grabbed some, and the icy feeling was chilling.

Xiao Zhu thought that her young lady was trying to use a trick to take out the ice from her Qiankun bag.

As a result, I watched with my own eyes as the water in the basin turned into ice little by little, my eyes widened in disbelief.

The lady really knows how to make ice!

Jiang Yue taught several maids how to make ice. Soon, several basins in the room were piled high with ice cubes, and the temperature in the room dropped instantly.

"Sister Yue'er, you are simply amazing! You can even make ice cubes, you are so amazing." Yao Chi held the ice cubes in her hands and turned them back and forth because she was freezing.

Prince Rong grabbed the ice and said thoughtfully, "Yue'er, it's very hot now, and many people have died of heatstroke on the road.

The team also needs ice, as people from every palace and family faint from heatstroke every day.

Especially for the elderly and children, I would like to ask, your method of making ice... can it be used... can it be used?"

It seems a bit difficult to say it, after all, this is someone else's ability, but he wants to use it to benefit the people, which is still a bit shameful.

Yao Chi understood Prince Rong's intention and finished for him, "Sister Yue'er, Third Brother wants to know if we can spread this ice-making method so that the people can use ice to cool down."

Jiang Yue thought, what’s the big deal!

Anyone who has studied chemistry today knows this.

"Of course, I have no problem with that. It's my duty to help the people. Now that these beauties have learned something, we can let them go out and teach others."

Jiang Yue took a cup and scooped a cup from the basin she had just made. "This ice is edible. It's delicious for making smoothies or fruit salad."

Yao Chi's eyes lit up. "Sister Yue'er, the cakes you taught the royal chef to make were delicious. I didn't expect you could make so many delicious dishes. Fruit salad, what is that? It sounds delicious."

Jiang Yue took a bite of ice and felt the heat in her heart subside.

"I'll go to the kitchen and make some for you this afternoon. This saltpeter can be used repeatedly.

After it melts, take out the saltpeter, dry it, and grind it into powder, and you can still use it."

Prince Rong's eyes moved slightly, "This can save a lot of saltpeter. Originally, the stock of saltpeter in each provincial capital and county pharmacy was not very large.

If it can be used repeatedly, the price of saltpeter will not be raised, and people will be able to afford it.

Yue'er, I want to thank you on behalf of the people. If there's anything you need, I'll go get it for you."

Jiang Yue waved her hands quickly, "No need, cousin, if you use something to exchange for my method, it would go against my original intention.

This is just my little trick, nothing to mention. I hope you guys will be more kind to me in the future, but please don't look down on me."

Yao Chi held Jiang Yue's hand, and everyone laughed.

Ice made from saltpeter can be reused. This is because saltpeter, chemically known as calcium nitrate, absorbs heat when dissolved in water, causing the temperature to drop, thus freezing the water.

This process is a physical change that does not alter the chemical properties of the saltpeter, so the saltpeter can be reused.

In order to use it again, you just need to separate the saltpeter from the water, dry it and then dissolve it again.

Concubine Liang nodded repeatedly, "Yes, Rong'er, this is a good thing that benefits the country and the people.

Hurry up and bring a few basins of ice to your father and tell him how to make it."

Prince Rong bowed and went to see the emperor with two maids and guards, carrying a basin of ice.

Xiaozhu, Hongmei and Bailian made a few more ice basins and brought water for people to wash their faces and hands.

Jiang Yue was indeed sweating from the tossing and turning just now, and she felt much cooler after washing.

Several maids took turns standing behind the ice basin and fanning the room. The cool air circulated in the room, making it feel more comfortable, and the maids were all smiling.

It's not hot at all standing behind the ice basin. They like this kind of work.

Emperor Mingde looked in surprise at the basin of ice that Prince Rong brought in, and watched the two maids demonstrate how to make ice with their own hands.

He quickly ordered the Imperial Hospital to remove all saltpeter to make ice and distribute it. He also notified the secret guards to contact all prefectures and counties, and to sell all the saltpeter in the pharmacies to the people at a low price, without raising the price. He also posted the method of making ice and made it known to the public.

It was not until several basins of ice were placed in the room that Emperor Mingde felt refreshed and his appetite was whetted.

When he heard Prince Rong say that the method of making ice was just discovered and invented by the daughter of Concubine Liang's younger sister, he really wanted to meet this little girl.

It was lunch time, so Prince Rong and I leisurely went to Concubine Liang's place.

The maid had just come in with the lunch box and hadn't set the table yet when Emperor Mingde came in.

Eunuch Huang waved his hand and asked the eunuch behind him to bring the food to the table. As there were many people, they moved it to the dining hall.

In a disaster year, there is not a single grain of harvest outside, not even a trace of green.

So now it is difficult for the emperor and the concubines to eat fresh vegetables and fruits. All they have are meat and dried goods.

Moreover, the weather was hot and the masters had no appetite, so the emperor ordered that the number of dishes in the entire palace be reduced by half, and he himself only had two dishes and one soup for each meal.
