"Okay, just remember these things. It's getting late today. General, go to bed early. I'm afraid we still have a lot to do early tomorrow morning."
"Then your Majesty, please rest early. It's really getting late."
The watch drum outside had already been beaten three times. It was indeed getting late, so Li Guang stood up and said goodbye.
Li Guang left, but Liu Deng still couldn't sleep all night, lying on the bed tossing and turning.
The conditions in the military camp are of course incomparable to those in the city. Even he, the king, can only sleep on a flat bed at this time.
Coupled with the sweltering weather now, the inside of the tent was like a steamer, which really made it difficult for Liu Deng to sleep.
"Your Majesty, why don't I go to the city to find you some ice cubes to cool off the heat?"
Listening to Liu Deng cooking pancakes on the bed, Shunzi hurriedly whispered outside.
"If you want ice cubes, why go to the city to find them? Go to the back camp to find some saltpeter for me, and bring me some larger copper basins."
Liu Deng thought for a while and then said.
"promise!"
Shunzi was a little confused, but still followed Liu Deng's order and went to the back camp to find what Liu Deng wanted.
Saltpeter is a commonly used material in the military.
Now that we are in a large army, getting some saltpeter is not something we can easily do.
It only took less than a moment to pour incense, and Shunzi had someone carry a large bag of saltpeter, and then brought several copper basins of different sizes over.
"Your Majesty, do you think these things are suitable for use?"
He looked at Liu Deng with a smile on his face.
"You guys come with me with your things. I will teach you how to make ice in summer today!"
The guards around him are all loyal, although they usually don't have much flattery.
But Liu Deng knew in his heart that when the critical moment came, they were the ones who would die for him.
Therefore, Liu Deng never hesitated to reward them generously.
This method of making ice is actually very simple.
But just by using the reaction between saltpeter and water, you can basically learn it by watching it once, so Liu Deng did not hide their intentions.
"Is this what your Majesty uses?"
Shunzi looked at Liu Deng in disbelief.
"It's enough to bring a few more buckets of water!"
Liu Deng pinched his nose and opened the bag that Shunzi carried. The smell of saltpeter was really a bit pungent.
Especially in this stuffy tent, this thing would almost make people faint.
However, in order to give them some benefits, Liu Deng was not ready to make this method public for the time being, so he could only endure it for the time being.
After hearing what Liu Deng said, the guards immediately brought several large buckets of water.
Liu Deng immediately directed them to pour all the water into the largest copper basin, then poured the saltpeter into it and started stirring continuously.
When saltpeter met water, it began to react violently.
After everything was stable, Liu Deng directed them to put a smaller copper basin into the large copper basin, and then poured clean water into it.
By the light of the giant butter candle in the room, the water in the small copper basin began to freeze visibly to the naked eye.
"The big, big, king is really frozen!"
Shunzi's eyes suddenly widened, and everything that happened in front of her was like a myth!
"Is it magical?"
Liu Deng looked at Shunzi with a smile.
"This, this, this, this..."
Shunzi pointed at the ice cubes that were condensing in the copper basin, with an incredible expression on her face. When she spoke, she could no longer utter a complete sentence.
"There are many other methods like this, and students coming out of the academy will learn some of them in the future!"
Liu Deng smiled and patted Shunzi on the shoulder.
"Your Majesty has such a good idea, why would you leave it to them?"
Shunzi didn't quite understand.
Saltpeter is actually not expensive, but ice is really expensive in summer.
And it is definitely something that has a price but no market. Except for the ice cellars dug by wealthy people, there is nowhere for anyone else to buy it.
If Shunzi had such a good idea, he would have already made a fortune from it, so how could he tell others about it.
"If you want to make money, there are many ways, so why care about these little gadgets? It's too late for you to study now. When you have children in the future, let them study properly! After all, always picking up a knife to kill people is not the same thing. A long-lasting thing!”
As Liu Deng spoke, he patted Shunzi on the shoulder, then reached out from the copper basin, picked up a small piece of freshly condensed ice and stuffed it directly into his mouth.
Feeling the long-lost coolness, the suffocating anger in my heart finally got better.
The smell in the tent was so strong that Liu Deng decided to take a walk outside.
The guards around him are all loyal to him. He can't watch these old brothers die in the end.
As for the war, according to the current development of the situation, in at most ten years, the Han army will be able to overwhelm Yu Nei.
When further development of gunpowder weapons was completed, the shape of warfare would change again.
By that time, rough guys like them who only know how to kill people with knives may not even be able to serve as soldiers.
But if you often walk by the river, your shoes will never get wet.
At this time, it is actually a good choice to teach them some ways to make a living and let them make some plans for their own future.
Seeing Liu Deng come out, Shunzi hurriedly followed. Although he was very curious, Liu Deng's safety was obviously more important than anything else.
"Why aren't you watching from inside?"
Liu Deng put his hands behind his back and blew in the night wind, and asked casually.
"Before departure, the Empress of the Kingdom personally warned that the king's safety must not be careless!"
Shunzi said seriously.
"There are so many dangers everywhere, okay, I'm just here to enjoy the breeze, you don't have to follow me all the time!"
"I'll stay away and won't disturb the king's peace!"
After Shunzi finished speaking, he took a few steps back, but still remained in Liu Deng's sight.
Seeing his persistence, Liu Deng stopped insisting.
When I looked up at the sky, the stars in the sky were shining brightly.
The night breeze was blowing and the stars were shining, but he could only think about murders and arson, which made Liu Deng laugh at himself.
The situation of human beings is really strange. Who would have thought that a social creature like myself would have times to worry about the country...
Walking under the stars, Liu Deng suddenly felt like his whole body was being washed.
After watching the stars, Liu Deng felt much better. There were several large ice basins placed in the tent.
The temperature in the tent suddenly dropped a lot, and Liu Deng was finally able to sleep peacefully.
