The starry sky is dotted with the night sea, and the stars in the sky are emitting the afterglow.

By the bonfire, Mo Feng had already opened the lid of the pot at this time. It was a layer of white solid. "Success?"

Thinking that his subordinates were faster, he took out the solids from the iron pot in a few seconds, cooled for a while, and then came forward after the solids were completely crystallized.

"Is this saltpeter?" Mo Feng murmured while pinching his chin. Refining this thing is not very complicated. It is mainly filtered and refined by stones soaked in feces and urine. For example, there are stones next to the toilets in rural homes, corners of pigpens, etc.

(Note: Ice making saltpeter, if you are interested, you can try it! Maybe you can really extract saltpeter and cover your mouth and hold your laughter!)

As he was skeptical, Mo Feng put clean water in a pottery jar, then made some crystallized saltpeter and put it in.

When the water enters, the saltpeter begins to melt.

Pinching his chin, Mo Feng murmured: "This reaction is not very intense!"

Ten breaths, twenty breaths, thirty breaths

At this time, the saltpeter crystals had completely dissolved in water. Mo Feng hesitated a little and poked his fingers deep into the water in the pottery jar. Suddenly, a hint of coldness came from his fingers. The clear water had turned cold and turned cold.

Bar smacked the corner of his lips and murmured in thought: "I think the amount of saltpeter is not enough to freeze it."

After saying that, he started to make arrangements again under the night.

…………

In a blink of an eye, it was dawn the next day.

The rising sun slowly rose, and the layers of mist that pierced the mountains fell down.

At this time, the women next to the river beach were still dealing with various fish quickly, but compared to dead fish like hills, their processing speed seemed very slow. Although the temperature in the mountains was not high at this time, if you put it like this, these fish would smell stinking for up to two days.

Seeing Mo Feng coming, Wang Zhan wiped his hands and hurriedly greeted him, saying bitterly: "Boss, if these fish are put down like this, it will probably not take long to get smelly. What should you do?"

"Refrigerate!" Mo Feng answered indifferently, and then said, "Go and call everyone over, I have a task arrangement."

Wang Zhan didn't understand why, but he still left in response.

After a while, nearly a hundred villagers had gathered. They looked at Mo Feng with curiosity and waited for Mo Feng's instructions.

"Everyone, too many dead fish are piled up by the river beach. If they cannot be dealt with in time, they will smell and rot." Mo Feng finished speaking, looked at everyone and said, "You put your hands on your hands first, and go to the forest to find places with more bird droppings and beast droppings. Once you find them, just transport the earth and stones below to me. Remember, don't have feces."

While saying that, Mo Feng rolled his eyes and looked at Chen Lan and the others. The latter three immediately turned red.

"Transport soil?" The villagers were stunned, and many people murmured: "Do you still need to build a house? But why do you need to use soil stained with feces?"

Wang Zhan hesitated a little and then waved his hand to command. Mo Feng's words were not to be disobeyed to him.

"Uncle Wang, is there a cave nearby?" Mo Feng suddenly rang out and asked.

"Cave?" Wang Zhan raised his eyebrows, but the young man beside him shouted hurriedly: "Boss, when I was looking for stone salt before, I found one, probably about seventy or eighty feet long."

Hearing this, Mo Feng showed joy and immediately shouted: "Take me over and take a look."

In just a moment, a natural hole.

Mo Feng and others walked in and walked around a little. The hole was very deep, at least twenty meters, and there were several winding branches, probably about seven or eight meters.

"Not bad, it's a good place." Mo Feng smiled while pinching his chin. The temperature here is not high, so it's just right to use it as an ice cellar. Thinking of it, Mo Feng said, "You can clear the weeds in the cave first. Also, let everyone know and let them transport the stones here."

...

The sun was gradually shining higher. Not far from the cave, several villagers were busy, with various containers in front of them, including pottery jars and bamboo tubes. There were all kinds of turbid liquids in the container, which gradually settled and clear.

"Boss, these have just settled!" The young man said, holding a basin of slightly turbid liquid.

"Just put that!" Mo Feng added dry firewood to himself, and in front of him were several burning pots.

As he said that, he put filter paper on again, and the basin of water was filtered and poured into the pot, evaporating and crystallizing.

Not long after, Mo Feng let out a heavy breath, looked at the pot of saltpeter in front of him, and the corners of his mouth curled up, and murmured: "These should be enough!"

As he said that, he waved to Chen Lan and others to move the pot of saltpeter into the cave. At the same time, he waved to everyone to start moving the crude custom-made rectangular wooden board molds into the cave, as well as cans of river water.

After finishing all this, it was already sunset and dusk. The people glanced around and saw that they finally finished what they needed, they all breathed heavily.

Wang Zhan glanced around the cave and saw all kinds of substances piled up. Then he wiped his forehead and vented heavy breaths and asked: "Boss, I've been busy all day, what are we going to do?"

"Refrigerate, build an ice cellar to freeze the white fish." Mo Feng explained casually.

"Frozen?" said the words, and the originally sluggish villagers instantly raised their eyes with an expression of disbelief.

Chen Lan pursed her lips and then showed a hint of bitterness and said, "Old, boss, the ancients said that it would be cold for three feet to a day, and it was almost June at this time, where can I get ice?"

As soon as this said, everyone nodded. Freezing can indeed be safe and prevented, but June is about to be around, and the earth will recover long ago. There is no possibility of ice!

Mo Feng shook his head with a smile on his face and said, "Get ice on the spot! In addition, what the ancients said is a fallacy, and it only takes three feet of ice to freeze for a moment!"

"Just, get ice on the spot?" Everyone was stunned and then trembled again. What did their boss say just now? Say the ancient sages were talking about fallacies? And it would be enough to freeze three feet and one quarter of an hour?

It's impossible, it's absolutely impossible, and the ancients would never deceive them.

Thinking of this, they all pursed their lips, looking disbelieving, but they didn't dare to shake their heads.

"Brother, can you really get ice on the spot?" Mo Xin flashed with clear eyes and said curiously. Only after his brother's serious illness has changed a lot, making her unfamiliar but sweet.

In the past, Mo Feng would not be so kind to her, nor would he be so kind to her.

After rubbing Mo Xin's little head, Mo Feng teased heartily: "Of course, because your brother is a god!"

"god?"

The people were stunned, and their eyes looked at Mo Feng with a slightly strange look. Then they concentrated on their minds and wanted to see what Mo Feng would do next. If he could really get ice on the spot, and with all the previous ones, I'm afraid he would be really a god.

At this time, rows of wooden boards are laid on the bottom layer. Then water is poured into the wooden board mold.

The shaking river water was slightly clear and also gathered everyone's eyes. At this time, Mo Feng picked up a portion of saltpeter and then slowly poured it into it under the gaze of everyone.

As soon as the water entered, everyone's eyes flashed, but the expectant eyes then turned into loss.

The river water has not changed much, it is still shaking, still clear. The only difference is that the crystals are rapidly getting smaller, as if they are melting.

"Hey!"

"Speak quietly!"

"Shh, this is impossible, it's nothing if it's not frozen!"

Everyone was talking privately, pulling each other's sleeves from time to time, as if reminding each other to be careful when speaking.

Ten breaths, thirty breaths, fifty breaths, and a hundred breaths!

Everyone sighed even more, and the loss in their eyes was obvious, but then there was a burst of self-deprecation because they shouldn't have expected it.

However, at this moment, a young man in front rubbed the corners of his eyes, then widened his eyes and shouted: "Ice, there is really ice. Look, the water surface is starting to freeze!"

When the words came out, everyone in the cave was stunned for a moment, and then they focused on looking.

I saw that a thin layer of ice slag on the surface of the water quickly condensed like thin swords. Moreover, the thin swords were rapidly becoming longer and wider. It was even said that not long before and after, the ice slag on the surface of the river had been cultivated into a piece.

"This, how is this possible? There is really ice?"

The people's mouths fell to the ground with their eyes flashing with incredible eyes. Especially the ice condensed in front of them, at a very fast speed, and it is not an exaggeration to say that it is visible to the naked eye.

The most important thing is that it is almost June, and the temperature in the cave is not low, so it is absolutely impossible to freeze.

"Gudu!" He swallowed a slutty saliva hard, and everyone's eyes wandered between Mo Feng and Shui. No, there was a shock in his eyes and a feeling that could not be expressed in words.

"Thick, thicker, and you'll see that the ice has become thicker." A young man screamed and pointed at the gradually whiter ice layer, as if it was a sign of getting thicker.

Looking at each other, everyone grew their mouths. The ice layer actually became thicker and thicker at the speed of the naked eye. Isn’t this saying that the ancient sage said that the three feet of ice that was not cold for a day was false words? It was lies.

Thinking of this, everyone's eyes completely looked at Mo Feng with a strange look, which was a look of wanting to kneel down and worship faith. In their eyes, Mo Feng was already a god, a god-like existence.

Whether it was the fish swimming in the river that floated up inexplicably, or the previous angrily smashing the wild boar king, or the three-foot freezing in front of them, they were all unimaginable.

"Go and fill other molds with water and make ice together." Mo Feng said.
