Deserted Island Survival Belt System

Chapter 343 Chapter 371, saltpeter will turn into ice when it meets water

"Because, after water combines with saltpeter, it will become..."

"ice!"

After Lin Qingxue gave the answer, Qin Fengyi was obviously stunned. How could saltpeter and water turn into ice?
"Really?" Qin Fengyi looked at Han Xuening with a confused face. He always felt that this was not right. How could stone and water turn into ice.

"That's right, saltpeter can absorb the heat in the water and drop it to the freezing point. That is to say, the amount of saltpeter is enough to completely absorb all the heat in the water." Han Xuening smiled slightly, "But we have liquid nitrogen, I think The effect of liquid nitrogen is more reliable than that of saltpeter, and it is quicker."

"I felt it more than once..." Qin Fengyi muttered to himself, "It's terrible to be uneducated, just like the author."

(Only just now, I learned that saltpeter mixed with water can actually freeze... As I have not graduated from junior high school, I am not suitable for writing high-end novels.)
"Haha, let you not study hard." Lin Qingxue smiled, "As the saying goes, if you learn mathematics, physics and chemistry well, you will not be afraid to travel all over the world."

"You are good at mathematics, physics and chemistry, and you are scared like a dead dog on a desert island." Qin Fengyi complained.

"This island is not normal..."

"Stop explaining!"

Seeing the two fighting each other, Han Xuening stopped her, "If you continue to fight like this, we will probably go home at night."

Yes, I don’t know how long the next road is. This narrow canyon stretches to the distance, and there is no end in sight. Speaking of it, this should be the canyon connected to the gold mine cave deep in the bat cave.

Speaking of which, Natasha and the others all passed by here, but the pirate group was wiped out except for Natasha, and even Natasha, who escaped by chance, was parasitized by the parasite.

Perhaps, there are still parasites here!
Thinking of this, Qin Fengyi didn't dare to be careless. He quickly ordered Saturday and Sunday to collect saltpeter. Both giant apes had huge double-edged axes. This weapon can be used to smash. I believe that the saltpeter on the canyon wall can be easily removed. down.

After several operations, a lot of saltpeter was indeed collected. This kind of stone is not very hard, and it is also very brittle. After hitting it with a double-edged ax made of gold, it did get a lot of saltpeter fragments.

These saltpeter fragments were packed in the backpacks carried by several people. There were three full backpacks, which were bulging and felt heavy on the back.

"It's so heavy..." Lin Qingxue put the heavy backpack on her back, muttering softly, "It feels like I'm back in junior high school."

"Junior high school...what the hell! Especially the class that only takes a few weeks..." Qin Fengyi thought for a while, there was a course, I really forgot what it was called, it seemed to be about planting, Similar to various courses for cultivating pumpkins and mushrooms.

"I only know that there are a lot of homework in junior high school. Every day after school, I will carry a heavy schoolbag on my back. All the homework adds up to several hours of homework." Lin Qingxue frowned, as if because the backpack on her back reminded her of her junior high school homework. bag.

"Also, the class you mentioned, I have the impression that it was the head teacher of Class 5 who taught us!" Lin Qingxue recalled.

"That's right, that woman who looks like a pig!" Qin Fengyi's entire class, and even the entire department, had a mysterious hatred for that woman.

Because the head teacher of the fifth class will ask you to take out the books for the class once every few weeks. Let you start copying, this is the homework assigned by that pig-like woman.

Generally speaking, the homework assigned by that woman is outrageous. A class lasts for 40 minutes, and the homework is assigned for a few minutes. The rest of the time is spent on homework. novel.

"Best friend! When I took this class, the homework I wrote was the sum of all the homework in a day... even far surpassed the homework of each day." Lin Qingxue recalled the saddest life in junior high school. The problem is that I have forgotten all the lessons now, it doesn't matter anyway, and I don't even take the exam during the exam.

"I still can't figure out what that teacher does!" Qin Fengyi was also speechless, what he taught, and he couldn't take the exam. Every time he took that class, the "teacher" would assign homework , I was copying homework all in one class, and I couldn’t even finish copying for more than 40 minutes.

This……

Is it really education?

(When I was in junior high school, this was an example...don’t ask me what the subject was called. After many years, I don’t know. I only know that the female teacher is the head teacher of Class .)
"It's said that going to work is stressful, and I think the pressure on students is also quite high." Han Xuening's ability to become a teacher shows that she was also a top student when she was in school, and that she has studied abroad.

"It doesn't matter anymore. There is no pressure from books here, only survival..." Qin Fengyi walked in the front and walked along the canyon for about 30 meters. The stones on both sides of the wall changed, and this place is no longer It was saltpeter, but granite.

They desperately wanted to rush back. The past few days after leaving the shelter were really hard.

However, they all resisted and survived successfully.

"Now I really want to go back to the beautiful hot spring, take a good bath, and then have some iced watermelon!" Lin Qingxue thought of the wonderful sanctuary, and a satisfied smile appeared on her small face.

When I was living on a deserted island at the beginning, I always wanted to go home, the big bed at home, and everything in the civilized world. I always looked out at the sea, hoping that a big ship would appear in the next second.

Afterwards, the current shelter came into existence. Although the conditions here were very simple compared with the civilized world, it also felt like home.

"If you freeze the watermelon, it can be done in ten minutes!" Qin Fengyi has several bottles of liquid nitrogen in his backpack. This kind of thing with a temperature of nearly minus 200 degrees can freeze the water in the bottles into ice cubes in just a few seconds.

"Big watermelon!" Lin Qingxue was obsessed, as if eating a delicious watermelon right now.

Walking along the canyon, you don’t have to be afraid of getting lost here, because there is only one road on the ground, and it didn’t take long before you came to a gravel. In front of you is the bat cave, but this is a collapsed cave.

"There's no way..." Lin Qingxue stared blankly at the blocked road ahead, staring at her big Shui Lingling eyes. It seemed that it was different from what she had imagined. This place was a dead end.

"Don't worry, don't forget, I can fly!" Qin Fengyi looked up at the sky, through the narrow canyon, he could see a line of sky.

However, the moment he raised his head, his pupils shrank for a while, as if he saw something!
