Daqin: When I return from sea, I will offer you a map of the world

Chapter 206 The First Emperor's scorching heat was unbearable, and Zhao Si's water turned into ice!

The establishment of an institution that is independent of the San Gong and Jiu Qing and has information about Xing Prison and even the independence of promotion channels is not achieved overnight.

At present, the establishment of the Black Ice Terrace has obtained the consent of 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, what 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 accidents in the past few days. Because of the massacre in Dongjun, the road ahead of the entire convoy was much smoother.

"It's so hot..."

With the passage of time, summer gradually came to an end, but the temperature did not drop but rose.

Autumn does not feel cool. With the arrival of the autumn tiger, the weather is getting hotter.

Others are fine, mainly because the first emperor suffered from his old problem and lost his appetite as the weather got hotter and hotter.

The most terrible thing is that there are no ice cubes to use. Not all local governments have basements for storing ice cubes, and Emperor Shihuang couldn't bring too many ice cubes, let alone effective long-term storage.

Of course, it was only a loss of appetite. Under the maintenance of the halo of uncut jade, at least the first emperor's body had no problems in other aspects.

However, due to the arrival of the autumn tiger, the driving away was getting slower and slower. The first emperor had no ice to use, so of course he couldn't drive in the sun.

By the way, how was ice-making done in ancient times?

Zhao Si had seen the specific process when reading novels in her previous life, but she had read too many things in her previous life, and she couldn't remember them for a while.

Seeing that Emperor Shi Huang's appetite was getting worse and worse, Zhao Si saw it and felt pain in his heart.

The main people are iron rice and steel, and now Emperor Shihuang eats less and less. Zhao Si has been thinking hard for the past few days, the method of making ice with saltpeter.

"I thought of it!" Zhao Si slapped his thigh fiercely, startling Wang Li who was sitting in a daze beside him.

"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 listless

"Make ice! I thought of a way to make ice!"

"Ice? Where do you get ice in these dog days?" Wang Li smiled, thinking that Zhao Si's head might be hot and confused.

"Never mind where I got it from!" Zhao Si rolled his eyes.

It was noon now, when the sun was hot, Shi Huang's car had to stop in this shaded place until the sun went down and it was not so hot before moving on, which happened to be convenient for Zhao Si to move.

Without any hesitation, Zhao Si stepped forward and led a group of soldiers out.

Wang Li became curious and led his horse to follow.

"Where are you going to get ice from? This generation has a basement for storing ice." Wang Li followed behind.

"Go to the toilet!" Zhao Si smiled.

"Where did you get the ice in the latrine? Are you burnt?" Wang Li patted the horse. Zhao Si's riding skills are getting better and better every day, so that Wang Li can'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 the villages in the countryside. After all, this is the border of the Central Plains, and the two river basins are basically livable areas everywhere. However, what Zhao Si didn't expect was that his team of soldiers with both bows and horses caused a commotion in the local area. .

To be honest, the pavilion chief, who upholds his conscientiousness, is numb.

But after Zhao Si and Wang Li presented their testimonials, the elders and the head of the pavilion were completely paralyzed...

The status is so high that they are obsequious while doing their duty.

"There's no need to report to the county captain, we won't stay here for long."

It's good to have local snakes like old folks and pavilion chiefs to greet them, at least it's much easier to find the toilet.

After Zhao Si expressed his needs, the old man fell into shock again.

With such a big momentum, just to find a toilet?

Does such a big person really use an earthen toilet?
……

The latrines in the village are really smelly...

But fortunately, Zhao Si also discovered the soil nitrate associated with the latrine.

"I fucking know why pork and dog meat are cheap meat in ancient times..." Zhao Si came out of the toilet, holding his nose, with a deep expression on his face.

Damn, there are pigs and dogs in the toilet.

To be precise, the toilet is built on top of the pigsty.

As we all know, dog, this thing eats shit.

Pig...he doesn't even pick a damn thing, he eats it too!

Obviously, in this day and age, manure is also an extremely precious resource.

Adhering to the choice of not wasting, pig and dog turned into old eight... The taste is the real taste...

Human excrement, pig excrement, and dog excrement are mixed inside... The pungent smell goes straight to the sky.

"Does it mean that dogs eat pig dung?" Zhao Si asked a very philosophical question while holding the nitrate wrapped in white paper in his hand.

"Why do you ask this? No, I should ask you what you are doing in the toilet?" Wang Li also had a bitter expression on his face, his facial features were almost wrinkled together.

"I was thinking, if you add dogs to eat pig manure, then the logical chain will be smooth, pigs eat human manure, dogs eat pig manure..."

"Stop!" Wang Li covered Zhao Si's mouth.

"I really regret believing your nonsense..." Wang Li sighed.

"I didn't ask you to come either, did I?" 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, how much ice can be produced from this small amount of dirt, and then we will search all the toilets of this generation!" Zhao Si said in a deep voice.

……

Thanks to the current bad and smelly hut structure between the villages.

The output of soil nitrate is really quite a lot.

Zhao Si ran with Wang Li and a group of soldiers for more than two hours.

Hmm... The toilets in the three townships were searched and wiped out.

More than 100 catties of soil nitrate were obtained.

Zhao Si led Wang Li and his soldiers back.

After returning home, he first went to take a shower. After visiting so many toilets, Zhao Si felt that his whole body was smelly.

After taking a cold bath, Zhao Si began to make ice with his own method.

"It's said that the ice made from nitrate can't be eaten directly, it should be..." Zhao Si's impression of this is still a bit vague because of the long time.

"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, and fill the small copper basin with water and place it in the large copper basin. Through temperature conduction, the ice formed by the condensation of water 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 in this era without pollution, just in case, plain water is the cleanest.

In ancient times when medical conditions were underdeveloped, there was no need to gamble with one's body whether the water was clean or not, whether there were parasites or not.

"I want to see how you get the ice out." Wang Li squatted beside him with a resentful expression and muttered to himself.

"It's also thanks to you and my friendship..." Zhao Si laughed when he heard the sound.

As far as Wang Li's reaction is concerned, in the novel, high and low are all villains who see people as low as dogs.

"Nitrate will absorb a lot of heat when it dissolves in water!" Zhao Si spread his hands and gave Wang Li the basic principles.

But the wait is long...

The sky was getting darker and darker. Although it was still hot, it was ready to drive. Although Meng Yi was able to drive, Zhao Si was too lazy to wait, leaving Wang Li there alone, waiting for him to drive.

It didn't take long to drive, and after about an hour, the sky gradually began to sink into darkness.

This is the case when the tiger comes in autumn, the temperature is higher than the hot summer, let alone the first emperor's loss of appetite, even the soldiers have some heatstroke when they are driving under the sun.

There is very little time to travel in a day, early morning and evening.

When 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.

After seeing Meng Yi, he suddenly remembered that this was the frame of Emperor Shihuang, and immediately stopped his exclamation.

Fortunately, Wang Li's backstage was strong enough, no one would care about such a small disrespectful behavior, Meng Yi just smiled and nodded to Zhao Si to signal Zhao Si to go and do his own work.

Follow Wang Li to the carriage pulling the ice making container.

I saw a total of four small buckets used to make ice, two of which had already formed smoothies.

"I just said it's okay!" Zhao Si clasped his hands together and gave a tactical back.

"It's amazing. Under the scorching sun, water can be turned into ice out of thin air, and the boiling water freezes first!" Wang Li looked at Zhao Si with a complicated expression.

"Is this a spell?"

Zhao Si shook his head: "Of course not..."

"Wait... what did you just say? Boiling water freezes first?"

Zhao Si stopped his pretentious thoughts and took a closer look. Sure enough, out of the four small buckets, only two of them had icy sand. Zhao Si reached out and touched the other two. 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 white were boiled, and two barrels were now 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 slightly cold boiled water, but the scalding boiled water that had just boiled.

"What the hell is the reason..." Zhao Si was stunned, this force was a bit incomprehensible.

"Is it because the heat absorption speed is different..." Zhao Si rubbed his brows.

Fortunately, Wang Li doesn't understand this, he just thinks that Zhao Si's ability to turn water into ice is awesome, and it's even more awesome to be able to turn boiling water into smoothies in these dog days.

"Don't worry about this issue yet." Zhao Si chose to ignore Zhao Si's knowledge blind spot when it came to it.

However, this interesting phenomenon can be recorded. Zhao Si can vaguely know that it must be related to the speed of heat absorption, but he can't tell the reason for a while, and it can be regarded as a topic for Mohist disciples later.

"Now that there is ice! We have to stop driving now, and we should set up camp and bury pots and cook food..."

It is also time to solve the problem of Shi Huangdi's loss of appetite.

Zhao Si planned to rub some cold and appetizing snacks for the First Emperor!
