Chapter 373 Ice Cellar

"You want me to go dig saltpeter? This thing has been there for a long time and I haven't dug it."

After much thought, Su Ranran happily decided on her goal for today.

"I feel like if I work harder, my career will be able to upgrade again after this solar term!"

Shu Lingyi was a little surprised: "The next upgrade will make me a high-level miner, right? So fast! I'm still far from being able to upgrade."

Su Ranran casually waved her hands at Shu Lingyi's envy, and did not forget to roll her eyes at Shu Lingyi: "You're kidding, I've been mining since I came to the territory, so I can say I haven't done anything else."

"I dig every day, digging this and that. I feel like I can dig corners with a pickaxe now. Even demolition work requires me to dig."

"..." Shu Lingyi was silent.

What kind of metaphor is this?!

"Laoran, do you know what strange things you are saying?"

Su Ranran turned around and realized what she was saying and smiled foolishly: "Hehe, I spoke too fast. Hehe~"

As long as she keeps laughing, the atmosphere won't be awkward!

After Xin Qing got up, she rushed to the door of Shu Lingyi's room to eat. Shu Lingyi was already used to it. He would put two square tables at the door of the room when he had nothing to do, and everyone would sit together to eat.

"I've urged my senior brother to go out! He will be here soon!"

Shu Ling nodded slightly. Many players should be arriving today, such as [Have you finished the continuous tasks], [Yan Huan], [Bai Moxi], etc...

She also specifically reminded the players to be careful not to head towards the north... otherwise they would be trapped in the beast tide and it would be difficult to rescue!

If they noticed it from a distance, they would have to take a detour, otherwise there would be too many monsters and it would be difficult for Shu Lingyi and the others to rush in and bring the people back safely!

Thinking of this, Shu Lingyi had to trouble Luo Zhiqing to make some more concealing feather clothes today.

Anyway, a lot of bird monsters were killed last solar term, including a lot of owls and crows, so Luo Zhiqing doesn't have to worry about lack of materials.

"No big deal. I made several more last night. When their relatives come over, if they can't avoid the monsters, just wear this. If you're careful, I should be able to sneak in before you."

“Okay, okay!”

Shu Lingyi looked at Xin Jing who was eating happily at the side, and suddenly asked her: "Um, Xin Jing, do you know the relationship between saltpeter and obsidian?"

Shu Lingyi didn't know much about obsidian, so he couldn't imagine what the relationship between saltpeter and obsidian was.

I asked other people but no one gave an answer. Even many people on the public screen didn't even know what obsidian was.

[Confused]: "My ID is my answer to this question."

[One Two Three Seven Seven Seven]: "Stupid and confused, haha. Although I don't know either, it involves a blind spot in knowledge."

[Cai Cai Cai Li]: "Before the boss asked this question, I didn't even know what obsidian was..."

[Simple or not]: "This looks like a decoration? I seem to have heard of an obsidian bracelet before."

The players in the public screen were in the same boat as her, and after arguing for a long time, there was still no conclusion.

She was expecting two top students to come and give a clear explanation, but in the end, none of them showed up.

If you ask Xiao Ai about it, she won't tell you anything even if she dies. It's really abominable to keep you in suspense.

[Don't be ashamed to ask, someone will give you the answer. Anyway, if you are thick-skinned, ask others what's wrong! ]

Seeing the righteous tone, her fist responded.

Xin Jing slurped a mouthful of noodles and thought for a moment: "These two things should have nothing to do with each other..."

There was something in her mouth and she spoke slowly. Just when Shu Lingyi felt a little disappointed, she continued, "If you insist on making a connection, it's probably because saltpeter can make ice."

"How can you say that?"

Shu Lingyi blinked his eyes. The others were also curious. Shu Lingyi had asked this question just now but no one answered the question.

"Obsidian is formed when magma suddenly solidifies after a sudden drop in temperature. Usually, when a volcano erupts, only the magma falls into the sea? Or into the river?"

"Anyway, if there is too little water, it will just evaporate. Unless it is a big river or sea, it has to be a big lake. If there is enough ice, saltpeter may have a similar effect?"

Xin Jing couldn't be completely sure either. Her idea was just a guess, after all, she had never done this experiment herself.

“I see!”

Shu Lingyi nodded thoughtfully, then patted Xin Jing's shoulder and said, "Then you and Ranran should go dig for saltpeter today."

"Oh! Could it be that Boss Yi wants to use saltpeter to make ice and then wait for the volcano to erupt to get some obsidian?!"

Xin Jing is not stupid either. She also went mining with Su Ranran yesterday, but like Su Ranran, she didn’t think about the volcano.

After all, according to other veteran players in the territory, the volcano has been there for a long time, and she had forgotten for a moment that volcanic eruptions must be accompanied by earthquakes.

The system is so shitty, there is no way it can arrange any good days for the players.

"Yes, Qi Xuanze needs obsidian to make seismic isolation bearings. I asked on the public screen where I could buy it, but they said there was none."

"I didn't expect it to be waiting for us here! After the volcano erupts, only players with large rivers and lakes will have a chance to mine obsidian."

"But who's stupid enough to live near a volcano that's about to erupt?!"

Shu Ling smiled bitterly. There were too few people who could meet the requirements. He might as well do it himself! He used ice cubes to get a lot of obsidian.

Self-reliance is best.

"Hey, that's no problem. I'll dig up saltpeter today and prepare a few large containers. I'll also prepare some water, and then I can make ice."

"Well, when the time comes, Boss Yi, can you spare a cellar to store these containers?"

Xin Jing drank the last mouthful of soup and smiled sweetly.

"Containers... Then I'll make these stone jars. Wooden barrels might freeze and crack..."

Shu Lingyi was stumped by the new problem. Making ice with saltpeter was not difficult, but it currently required a large enough container to hold water, and when the water froze, the container had to be able to withstand low temperatures.

"And one more thing. The ice has to be storable after it's made. Otherwise, it will melt quickly in this weather."

"If we rely on the cellar alone, I'm afraid the ice won't last long before it's scratched away. The cellars that the boss built before weren't very deep, and the depth of the ice cellar must be at least six meters."

Xin Jing raised all these issues, and Shu Lingyi began to ponder over countermeasures.

Qi Xuanze: "The ice cellar is nothing more than a little deeper. I have also made enough cement and obsidian. I need it. I can choose a place here to dig deeper to use as an ice cellar."
