The formation of an organization that is independent of the Three Princes and Nine Secretaries 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 Platform has been approved by the accompanying civil and military officials, and as for the civil and military officials who stayed in Xianyang, it is obvious that they only need to be notified.

are all left behind in Xianyang, what more decision-making power do you need?

The road is long and bumpy......

Zhao Si continued to drive for Wang, and it is worth mentioning that there have been no accidents in the past few days, because of the killing of Dongjun, the road of the entire convoy has been much smoother.

"It's so hot......"

As time passed, summer gradually came to an end, but the temperature did not fall but rose.

Autumn didn't feel cool, and with the arrival of the autumn tiger, the weather became hotter.

The others are fine, mainly because the first emperor has become hotter and hotter, and the first emperor's old problem has been committed again, and he has lost his appetite.

The worst thing is that there is no ice cubes, not all local governments have basements to store ice cubes, and the first emperor can't bring too much ice cubes, let alone effective long-term storage.

Of course, it was just a loss of appetite, and under the maintenance of the Puyu aura, at least the First Emperor's body did not have problems in other aspects.

However, because of the arrival of the autumn tiger, the drive is getting slower and slower, and the first emperor has no ice cubes, so of course he can't rush against the sun.

How did you get ice making 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 he couldn't remember it for a while.

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

The main person is iron rice is steel, and now the first emperor eats less and less, Zhao Si has been thinking hard about the method of making ice from saltpeter these days.

"I thought of it!" Zhao Si slapped his thigh fiercely, scaring Wang Li, who was sitting on the side in a daze, stunned.

"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 in a state of exhaustion

"Ice! I've figured out how to make ice! ”

"Ice? Where do you get ice from these dog days? Wang Li smiled, only to feel that Zhao Si's head was not hot and confused.

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

It was noon now, and when the sun was hot, the First Emperor's drive had to stop in this shady place until the sun was not so hot before continuing to travel, just enough to facilitate Zhao Si's action.

Without any hesitation, Zhao Si slapped his horse and came out with a team of soldiers.

The king was curious, and led his horse to follow.

"Where are you going to get the ice from? This generation is enough to choke on the basement where ice is stored. Wang Li followed behind his ass and spoke.

"Go to the toilet!" Zhao Si smiled.

"Where does the latrine get the ice? Confused? Wang Li patted the horse, Zhao Si's current riding skills are getting better and better, so that Wang Li can't keep up with Zhao Si's speed.

"Go to the villages around here!" Zhao Si took the soldiers and went straight away.

The villages in the township are not difficult to find, after all, this is the boundary of the Central Plains, the two river basins, and there are basically habitable areas everywhere, but what Zhao Si didn't expect was that his whole team of all-armored soldiers with both bows and horses caused local commotion.

To be honest, the pavilion chiefs who uphold their due diligence are numb.

And after Zhao Si and Wang Li showed the test, the village elders and pavilion chiefs were numb......

The status is so high that they have to grovel while doing their duty.

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

It is still beneficial to have the village elders and pavilion chiefs to greet them, at least it is much easier to find a toilet.

After Zhao Si expressed his needs, the villager was once again shocked.

The momentum is so loud, just to find a latrine?

Is such a big character really using a dirt toilet?

……

The latrines in the township, they really stink......

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

"I know why ancient pork and dog meat were cheap meat......" Zhao Si covered his nose and came out of the toilet with a deep face.

Fuck, 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 he eats.

Pig...... Don't fucking pick this 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, pigs and dogs incarnate the old eight...... Taste is the real taste......

Inside, human dung, pig dung, dog feces are mixed...... The pungent smell rushed straight to the Heavenly Spirit Gai.

"Do dogs eat pig manure?" Zhao Si held the nitrate wrapped in white paper in his hand and asked a very philosophical question.

"What is this, you ask? No, I should ask you what you do with the latrine? Wang Li also had a bitter face, and his facial features were almost wrinkled.

"I'm 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 call you either, did I?" Zhao Si rolled his eyes.

"What's next? Aren't you looking for ice from the latrine? What about ice? The king asked.

"What do you think, just how much ice is enough to get out of this bit of soil and nitrate, and then we have to clean all the latrines of this generation!" Zhao Si spoke in a deep voice.

……

Thanks to the current poor and smelly thatched hut structure in the township.

The output of soil nitrate is really a lot.

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

Well...... The latrines in the three townships were completely scavenged.

I got more than 100 catties of soil nitrate.

Zhao Si led Wang Li and his soldiers to turn back.

After going back, he first went to take a shower and visited so many toilets, Zhao Si felt that his whole body was stinky.

After taking a cool shower, Zhao Si began to make ice on the ground.

"Anyway, the ice made of nitrate can't be eaten directly, it should be ......" Because the time is too long, Zhao Si really has a vague impression of this.

"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.

The large copper basin is filled with water and placed in the large copper basin, and the temperature is conducted, so that the ice condensed by the water in the small copper basin does not contain nitrate.

It is worth mentioning that Zhao Si uses boiled water.

Don't talk about what well water stream water is pollution-free in this era, just in case, or boiled water is the cleanest.

In ancient times, when medical conditions were not developed, there was no need to gamble on whether the water was clean or not, and whether there were parasites.

"I'm going to see how you get this ice out." Wang Li squatted beside him with a resentful expression and muttered to himself.

"It's also thanks to you and me......" Zhao Si was happy when he heard it.

As far as Wang Li's reaction is concerned, he is a villain who looks down on people with dog's eyes.

"Nitrate dissolves in water and absorbs a lot of heat!" Zhao Si spread his hands and gave Wang Li a basic reason for popularizing science.

But the wait is long......

The sky gradually darkened, although it was still sultry, but it had reached the conditions for rushing, although Meng Yi could also drive, but Zhao Si was too lazy to wait, leaving Wang Li alone to wait for him to run away and drive.

It didn't take long to get on the road, and after about an hour, the sky gradually began to fall into darkness.

Autumn Tiger is like this, the temperature is higher than the hot summer, not to mention that the first emperor has lost his appetite, even the soldiers are a little heatstroke when they are in a hurry against the sun.

There are very few hours of the day to travel, early in the morning and late in the 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 in high spirits.

Later, when he saw Meng Yi, he suddenly remembered that this was the frame of the First Emperor, and immediately stopped his exclamation.

Fortunately, Wang Li is hard enough from the backstage, no one will care about this kind of small faux pas, Meng Yi just smiled and nodded to Zhao Si and motioned for Zhao Si to go and busy himself.

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

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

"I just said yes!" Zhao Si clasped his hands and came to a tactical back.

"It's really a god, it can really turn water into ice out of thin air under such a scorching sun, and it is actually boiling water that freezes first!" Wang Li looked at Zhao Si with a complicated expression.

"Is this a spell?"

Zhao Si shook his head: "Of course it's not ......"

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

Zhao Si stopped pretending to be forced and looked at it, sure enough, of the four small barrels, only two of the small barrels were frozen, and the other two, Zhao Si reached out and touched it, the temperature was indeed very cold, but it was obviously not yet frozen.

For the safety of the first emperor's life, Zhao Si used boiled water.

Among them, two buckets of ready-made Liangbai were opened, and two buckets were boiled, and they were thrown into the saltpeter aqueous solution.

Zhao Si remembered this very clearly, what he didn't expect was that the first thing to freeze was not the slightly cooler cold boil, but the boiling water that had just boiled.

"What the hell is this principle...... Zhao Si was stunned, this force is a little inthorough.

"Is it because of the difference in heat absorption speed......" Zhao Si rubbed his eyebrows.

Fortunately, Wang Li didn't understand this, he just thought that Zhao Si was very awesome at being able to turn water into ice, and it was even more awesome to be able to make a smoothie from boiling water in these dog days.

"Don't dwell on that just yet." When it comes to Zhao Si's knowledge blind spots, Zhao Si chooses to ignore them.

However, this interesting phenomenon can be recorded, and Zhao Si can vaguely know that it must be related to the speed of heat absorption, but he can't tell the principle for a while, and he can just throw it as a subject to the disciples of the Mo family.

"Now there's ice! Now the driving must be stopped, and it is time to set up camp and bury the pot to cook..."

It's also time to address the First Emperor's loss of appetite.

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