Suo Hong was stunned, I can understand ice-making, why are you running to the edge of the manure tank?

You must know that in the Jiangling military camp, there are almost 50,000 infantry cavalry sailors, plus the Wuxi barbarians in Shamosong, 50,000 is not much more.

With so many people eating, drinking, and Lazar together, you can imagine how much the manure tank in the barracks smells.

Although at the request of Yao Yu, the barracks paid great attention to hygiene, and resolutely put an end to all possible plague outbreaks.

However, it's okay if you don't get close, and if you get close, the smell can still kill people.

No, as soon as they walked up, Lu Bi and He Xiong pinched their noses and said, "Lord (adult), spicy eyes." ”

Yao Yu sighed: "It's okay, bear with it first." Oh, stuff your nose with a stone. ”

As he spoke, Yao Yu grabbed a handful of pebbles from the ground.

Seeing this scene, all that was left for Lu Bi Hexiong was dry and speechless.

Looking at Suo Hong again, while covering his nose with his sleeve, he asked Yao Yu in a loud voice: "Jun Hou, we didn't come here to smell the smell, right?" ”

"How can it be, I said I wanted to make ice. Lu Bihexiong, don't be stunned, take the shovel and the crockpot, and see that there is no hoarfrost on the wall around the manure tank, all of them are scraped off for me and put in the crockpot. ”

Lu Bihexiong didn't understand: "Lord (lord), what do you want this thing for?" ”

"Anyway, it's used to make ice. Okay, don't ask, go quickly. ”

Under Yao Yu's urging, the two of them couldn't resist, so they could only agree.

No, the two of them went to the front and started to work, and Yao Yu and Suo Hong looked at it with their noses plugged.

Their behavior made Yongji, who was training the soldiers next to him, suspicious.

So, he handed over the task of training the soldiers to Lian Jun, and he led a few guards to come to him and asked Yao Yu: "My lord, is there anything wrong with this military camp?" Why did you let Lu Bi Hexiong go around in circles on the edge of the manure tank? ”

Yao Yu explained his plan with a smile while commanding Lu Bi Hexiong.

Hearing Yao Yu's explanation, Yong Yu was taken aback: "Ice making? Can this thing make ice? ”

"You see, you don't understand that. If I say yes, then I can. Lu Bi Hexiong, don't be lazy, scrape more, there are more things, hurry up. ”

was said by Yao Yu, and the two of them had no choice but to continue to work hard.

Soon, the two scraped a jar full of cans, and that's it, the wall was scraped not a ten-thousandth.

The two of them came back with a full clay pot, and after picking out the stones in their noses, they gasped for breath, and muttered stinking words over and over again.

Looking at Yao Yu again, he smiled happily, and he looked at the crockpot in the arms of the two: "It's done." Next, the ice is made. ”

After speaking, Yao Yu asked Yong Yu to prepare a vacant lot and a large vat for himself, and then he first asked Lu Bi Hexiong to dig a big pit in the ground with a shovel and smear yellow mud to prevent water loss.

Then, Yao Yu put the vat into the pit again, filled the vat with water, and asked Lu Bi and He Xiong to put the hoarfrost scraped off the wall into it.

To be honest, there weren't many of the two crockpots, and they didn't cover the bottom.

So, Yao Yu looked back at Lu Bi Hexiong with ill intentions in his eyes.

Noticing Yao Yu's gaze, Lu Bihe's heart jumped, and the corners of his mouth couldn't help twitching: "Lord (adult), you don't still want us to go, do you?" ”

"Look, isn't that pretty smart, okay, since you guessed it, go ahead, obedient. The ice will be made later, and the first one will be enjoyed by both of you. ”

The two of them wailed, so they could only shake their heads and turn back to the edge of the cesspool and continue to scrape.

Seeing Yao Yu's behavior, Suo Hongyong was even more confused: "My lord (Jun Hou), what are you going to do?" ”

Yao Yu said it: "Don't I say it, make ice." ”

In this way, Lu Bihe Xiong kept busy, running back and forth more than 20 times, and finally collected half a pit of hoarfrost in the pit.

Then, Yao Yu asked Lu Bi Hexiong to take water and pour it into the pit to mix with hoarfrost.

After doing this, he asked Yong Ju to fetch a piece of oilcloth to cover the pit and the mouth of the water tank in the pit.

After finishing the fight, Yao Yu slapped his palm: "It's done." ”

Suo Hong looked confused: "Jun Hou, you don't want to say that you can make ice just like this, right?" Just kidding, it's not. ”

"Don't rush to conclusions, there's a time limit for this thing to make ice, wait two hours and you'll know."

When the words landed, Yao Yu turned his head and said to Chong Yong: "Take advantage of this time, go, go and see how the soldiers are training." ”

In this way, Yao Yu stayed in the barracks for two hours in a row.

It was already late and he didn't go home, but had a simple meal with the soldiers in the barracks.

When night fell, two hours was enough time, Yao Yu ended the bragging with the grassroots generals, and called Suo Hongyong and said: "Next, it is the time to witness the miracle, go, go and see our ice." ”

After speaking, Yao Yu led the way and walked in the front.

Although Suo Hong and Yong were suspicious in their hearts, when they saw Yao Yu so confident, they had no choice but to stand up and keep up, believing that Yao Yu this time.

To make a long story short, when everyone came to the pit dug during the day, Yao Yu asked Lu Bi Hexiong to open the tarpaulin as soon as possible, and from the pit, a cool air immediately came out.

This big night really made everyone by the pit shiver.

Yong Ju raised the torch to illuminate it, and saw that in the large water tank in the pit, a thin layer of ice crystals formed on the surface.

Yao Yu reached forward and stabbed a handful, and ice water flowed from between his fingers.

Suo Hongyong was shocked: "Really, it can really freeze!" ”

Yao Yu nodded: "That's a must." Otherwise, wouldn't it be in vain that Lu Bi Hexiong was busy this afternoon? ”

The two of them were speechless: "Lord (adult), don't say it, it stinks us to death." Now we both feel like we smell in ourselves. ”

Yao Yu laughed: "The so-called capable people work harder." You two are so powerful, it's okay to do a little more. ”

Two: "···"

At the same time as the joke, Suo Hong subconsciously squatted down and reached out to fish in the water tank, and at the same time, he turned back to Yao Yu and asked, "Jun Hou, how did you do this?" Why is it that the water is fine in the afternoon, and it freezes after a while? ”

Yao Yu smiled and asked Lu Bi to re-cover the tarpaulin, and then said, "This is called the nitrate ice method." Nitrate is not only a firestarter, but also an ice cube. ”

When he said this, Yao Yu couldn't help but feel a little proud.

The phenomenon of nitrate ice making is very easy to understand in the modern society in which I live, which is nothing more than that when nitrate and water are dissolved, it will take away a lot of heat, so that the temperature in the tank will drop, and the water will further condense into ice.

Of course, this method is not unique to modern times, in fact, as early as the Song Dynasty, the common people have mastered this method of ice making, so that the people can also enjoy cold drinks in summer.
