The establishment of an organization that was independent of the Sangong and Jiuqing and had access to Xing Prison information and even independent promotion channels was not accomplished overnight.
At present, the establishment of the Black Ice Platform has been approved by the accompanying civil and military officials. As for the civil and military officials staying in Xianyang, it is obvious that they only need to be notified.
They are all left behind in Xianyang, so what kind of decision-making power do they need?
The journey is long and bumpy...
Zhao Si continued to drive for the king. It is worth mentioning that there were no unexpected incidents in the past few days. Because of the killing spree in Dongjun, the road ahead for the entire convoy was much smoother.
"It's so hot..."
As time goes by, summer is gradually coming to an end, but the temperature is rising instead of falling.
I don’t feel cool in autumn. With the arrival of autumn tiger, the weather is getting hotter.
Others were fine, mainly because as the weather got hotter and hotter, Shi Huangdi's old habit relapsed and he lost his appetite.
The most terrible thing is that there is no ice cubes to use. Not all local governments have basements to store ice cubes. Moreover, the First Emperor could not bring too much ice cubes with him when he was traveling, and there was no way to effectively store them for a long time.
Of course, it was just a loss of appetite. Maintained by the halo of raw jade, at least the First Emperor's health had no problems in other aspects.
However, due to the arrival of Autumn Tiger, the driving was getting slower and slower. The First Emperor had no ice to use, so of course he could not drive in the bright sun.
By the way, how was ice making made in ancient times?
Zhao Si had seen the specific process in his previous life, but he had seen too many things in his previous life and couldn't remember it for a while.
Seeing that the First Emperor's appetite was getting worse and worse, Zhao Si felt pain in his heart.
The main thing is iron rice and steel. Now the First Emperor is eating less and less. Zhao Si has been thinking hard these days about how to make ice with saltpeter.
"I thought of it!" Zhao Si slapped his thigh fiercely, frightening Wang Li who was sitting aside in a daze.
"Why are you yelling so loudly?" Wang Li rubbed his sleepy eyes. The weather was too hot. Not only the emperor lost his appetite, but everyone else was also depressed.
"Make ice! I thought of a way to make ice!"
"Ice? Where do you get ice in these dog days?" Wang Li smiled and felt that Zhao Si's head might not be too hot.
"Don't worry about where I got it from!" Zhao Si rolled his eyes.
It was noon now, when the sun was very hot, so the Emperor's driver had to stop in the shade until the sun went down and it was not so hot before continuing, which was just convenient for Zhao Si to move.
Without any hesitation, Zhao Si rode up and led a group of soldiers out.
Wang Li was curious and followed him with his horse.
"Where are you going to get ice from? This generation has enough basements to store ice." Wang Li followed behind and spoke.
"Go to the toilet!" Zhao Si smiled.
"Where did the ice come from in the toilet? Are you confused by the fever?" Wang Li patted the horse. Zhao Si's riding skills were getting better and better with daily practice, so much so that Wang Li couldn't keep up with Zhao Si's speed.
"Go to the nearby villages!" Zhao Si led the soldiers straight away.
It is not difficult to find villages in the countryside. After all, this is the border of the Central Plains and the two river basins. Basically, there are livable areas everywhere. However, what Zhao Si did not expect was that his entire team of fully armored soldiers with both bows and horses caused a local commotion. .
To be honest, the director of the pavilion who upheld his duties and responsibilities was numb.
And after Zhao Si and Wang Li presented their testimony, the village elder and the pavilion chief fell into anesthesia...
Their status is so high that they have to grovel while performing their duties.
"There's no need to report to the county captain, we won't stay here long."
It's good to have local bosses like the village elders and pavilion chiefs to greet you. At least it will be much easier to find the toilet.
After Zhao Si expressed his needs, the village elder was once again shocked.
There is such a big momentum, just to find a toilet?
Is such a big man really used to using earthen toilets?
…
The toilets in the countryside really smell...
Fortunately, Zhao Si also discovered the soil salt that accompanies the toilet.
"I fucking know why pork and dog meat were cheap meat in ancient times..." Zhao Si covered his nose and emerged from the toilet with a serious look on his face.
Damn it, there are pigs and dogs in the toilet.
To be precise, the toilet is built on top of the pigsty.
As we all know, dogs, this thing eats shit.
Pig...he doesn't even have a damn choice about this thing, he eats it too!
Obviously, in this era, feces is also an extremely precious resource.
Adhering to the choice of not wasting, pigs and dogs transform into old people...the taste is real...
Human feces, pig feces, and dog feces were mixed inside... The pungent smell reached Tianling Gai.
"Do dogs eat pig manure?" Zhao Si asked a very philosophical question while holding the saltpeter wrapped in white paper in his hand.
"Why are you asking for this? No, I should ask you why you got into the toilet?" Wang Li also had a bitter look on his face, and his facial features were almost wrinkled.
"I was thinking that if we add dogs eating pig excrement, then the logical chain will be smooth. Pigs eat human excrement, dogs eat pig excrement..."
"Stop!" Wang Li covered Zhao Si's mouth.
"I really regret believing your lies..." Wang Li sighed.
"I didn't ask you to come, right?" Zhao Si rolled his eyes.
"What's next? Aren't you looking for ice from the toilet? Where's the ice?" Wang Li asked.
"What are you thinking about? This little bit of saltpeter is enough to make a lot of ice. Next, we will raid all the toilets of this generation!" Zhao Si said in a deep voice.
…
Thanks to the poor and smelly hut structure currently in the countryside.
The output of soil saltpeter is really quite a lot.
Zhao Si ran with Wang Li and a group of soldiers for more than two hours.
Well...the toilets in three villages were completely looted.
I got more than 100 kilograms of soil saltpeter.
Zhao Si led Wang Li and his soldiers back.
After returning home, he first took a shower and visited so many toilets that Zhao Si felt that his whole body stank.
After taking a cold bath, Zhao Si began to make ice in his own way.
"Speaking of which, ice made from saltpeter cannot be eaten directly, right..." Because it was so long ago, Zhao Si's impression of this point was really vague.
"After all, it's for the First Emperor, just in case." Zhao Si pondered for a moment and chose to use large and small basins to make ice.
Pour water into the large copper basin and add nitrate. Fill the small copper basin with water and place it in the large copper basin. Through temperature conduction, the ice formed by the water condensing in the small copper basin does not contain nitrate.
It is worth mentioning that Zhao Si used boiled water.
Don't talk about well water and stream water being pollution-free in this era. Just in case, boiled water is the cleanest.
In ancient times when medical conditions were not developed, there was no need to gamble with one's own body on whether the water was clean or whether there were parasites.
"I want to see how you make this ice." Wang Li squatted beside him with a resentful look on his face and murmured to himself.
"Thanks to you and me for being good friends..." Zhao Si was happy when he heard this.
As for Wang Li's reaction, he is a villain who looks down upon others.
"Nitrogen dissolves in water and absorbs a lot of heat!" Zhao Si spread his hands to explain the basic principles to Wang Li.
But the wait is long...
The sky gradually darkened, and although it was still sultry, conditions were met for the journey. Although Meng Yi could also drive, Zhao Si was too lazy to wait, leaving Wang Li alone to wait for him to run away and drive.
Not long after the journey, about an hour or so, the sky gradually began to fall into darkness.
Autumn is like this when tigers come. The temperature is higher than that in hot summer. Not to mention that the First Emperor lost his appetite, and even the soldiers suffered from heat stroke while rushing in the bright sun.
There are very few hours in a day to travel, early morning and evening.
Just as the drive was about to stop again, Wang Li suddenly ran over.
"It's done! It's done! It's really done!" Wang Li came to greet Zhao Si excitedly.
Then when I saw Meng Yi, I suddenly remembered that this was the frame of the First Emperor's bicycle, and immediately stopped my exclamation.
Fortunately, Wang Li was tough enough backstage, so no one would care about such a small disrespect. Meng Yi just smiled and nodded to Zhao Si, telling Zhao Si to go about his business.
Following Wang Li, he quickly arrived at the carriage pulling the ice-making container.
I saw a total of four small buckets used for making ice, two of which had already formed smoothies.
"I just said it's okay!" Zhao Si folded his arms and made a tactical retreat.
"It's amazing. You can turn water into ice out of thin air under the scorching sun, and it's the boiling water that freezes first!" Wang Li looked at Zhao Si with a complicated expression.
"Is this a magic trick?"
Zhao Si shook his head: "Of course not..."
"Wait...what did you just say? Boiling water freezes first?"
Zhao Si stopped pretending to be cool and took a closer look. Sure enough, of the four small buckets, only two were filled with ice cream. Zhao Si reached out and touched the other two. The temperature was indeed very cold, but it was obviously not frozen yet. to the point of freezing.
For the safety of the First Emperor, Zhao Si used boiled water.
Among them, two barrels of ready-made cold boiled water were made, and two more barrels were boiled, and they were thrown into the saltpeter solution.
Zhao Si remembered this very clearly. What he didn't expect was that the first thing to freeze was not the cold boiled water with a slightly lower temperature, but the scalding hot water that had just boiled.
"What the hell is this principle..." Zhao Si was stunned, this guy was a bit pretentious.
"Is it because the heat absorption speed is different..." Zhao Si rubbed his eyebrows.
Fortunately, Wang Li doesn't understand this. He just thinks that Zhao Si's ability to turn water into ice is awesome, and being able to turn boiling water into smoothies in these dog days is even more awesome.
"Don't worry about this issue yet." When it came to Zhao Si's knowledge blind spots, Zhao Si chose to ignore it.
However, this interesting phenomenon can be recorded. Zhao Si could vaguely know that it must be related to the speed of heat absorption, but he couldn't explain the reason for a while, so he could just turn it into a topic and throw it to the Mohist disciples.
"Now there is ice! Now the driving has to stop, it's time to set up camp and bury the pot to make rice..."
It was also time to solve the problem of Emperor Shi Huang's lack of appetite.
Zhao Si planned to give the First Emperor some cold and appetizing snacks!
