"Well, we only have two bags." The orc guarding the stall dragged two more bags and opened them to show him.
After checking and confirming that it was all saltpeter without any other stones mixed in, Meng Yuqing looked at the chain.
So Lian continued to negotiate the price with the other party.
Although Meng Yuqing showed great desire for saltpeter, the other party did not quote a high price, only slightly more expensive than graphite.
After all, they think saltpeter looks better than graphite.
Lian didn't know what the two stones were used for, and the other party didn't know either, so the price was calculated based on the decoration.
At this time, Ya and another orc also came over. Lian gave a bag to Ya to hold, and the few of them prepared to leave.
Before leaving, Meng Yuqing looked at the orcs guarding the stall and said, "We should need these white stones for a long time. We will collect some every year. The black stones may not be needed until they are used up. If you are willing, you can take some time next year to bring these things directly to our tribe and exchange them with us."
The orc guarding the stall originally thought that this was a one-time deal. After all, what use could these stones be?
The stone is durable and will not go bad after being stored for a long time. It is generally difficult to replace it again after it has been replaced once. Not every stone is like yellow light stone.
The orcs guarding the stall looked excited. Meng Yuqing's words meant that they could rely on this white stone to continue trading with this big tribe in the future.
He looked at Meng Yuqing and asked, "Excuse me, how do I get to your tribe?"
Meng Yuqing looked at Lian and Ya. They exchanged a glance before Lian stepped forward and said, "Walk along the river in that direction for about twenty days, and you'll see a stone wall taller than the trees. That's our tribal territory. Head toward the stone wall. We have flying orcs patrolling the sky. When you see them, just call out to them and explain your purpose."
The orc guarding the stall nodded as he listened. In fact, it was very risky for a small tribe like theirs to go to other tribes to trade, but the environment near their tribe was really too bad.
If there is a way to make their lives better, they are willing to try it.
Take these stones back. Since Xuan hasn't come back yet, he can only ask Lian and Ya to help him.
Meng Yuqing took them both to a corner with few people, looking mysterious, and Lian was quickly piqued by him.
Even Ya, who had been clearly in a bad mood recently, showed an interested expression.
"Yuqing, what are you doing?" Lian asked Meng Yuqing who was holding a few pieces of saltpeter in her hand.
"Shh, don't ask, you'll know when I'm done." Meng Yuqing looked proud.
He asked Ya to make a fire to boil water. After the water boiled, he threw saltpeter directly into the water and stirred it constantly with a small wooden stick.
Soon the saltpeter disappeared. He looked through the space warehouse and took out a small fan he had made with dry grass. He placed it on another stone jar and used it as a simple filtering tool to filter the water containing the dissolved saltpeter.
Some gravel and larger grains of sand were kept out.
After throwing away all the debris, he fanned the stone jar frantically to speed up the cooling of the water in the jar.
After a while, some white crystals began to precipitate out of the jar.
He carefully collected the simply purified saltpeter.
Lian and Ya watched him operate in confusion.
"Don't be anxious, it's not over yet." Meng Yuqing said casually.
Then he took out a ceramic basin and a small ceramic bowl from the space warehouse.
"Lian, go get two cans of water."
Although Lian didn't know what he was going to do, he did it anyway.
After Lian pumped the water back, Meng Yuqing was ready with a stone jar filled with saltpeter.
"Fill the basin and bowl with water." Meng Yuqing said, pointing to the two pottery pieces on the ground.
After pouring the water, he waved to Lian and Ya, "Come here quickly, I'll show you a treasure later."
After hearing what he said, they both sat on the ground and stared at the pottery basin.
Seeing that everything was ready, Meng Yuqing poured the purified saltpeter from the stone jar into the ceramic basin filled with water, but did not put any into the ceramic bowl.
As the wooden stick stirred, Lian and Ya's eyes gradually widened and they looked at the pottery basin and bowl in surprise.
Lian even reached out his hand to the ceramic basin and felt it, "It's cool."
Meng Yuqing chuckled and said, "The next moment is the moment to witness a miracle."
Tooth and Chain had completely surrounded them, their eyes fixed on the clay basin.
!!!
"Ice!" Although Lian lowered his voice, one could still hear the shock in his tone.
Ya even reached into the basin and felt around, "It's really ice."
He looked up at the sun in the sky and muttered, "It's summer now, and we can actually make ice."
"Haha, we don't have to be afraid of the heat in summer anymore." Meng Yuqing happily took the small ceramic bowl out of the ceramic basin.
He actually didn't expect to succeed in one go, especially he didn't expect that the liquid in the small ceramic bowl would also freeze successfully.
"Is this ice edible?" Lian suddenly asked when he was still immersed in the joy of success.
"The water in the basin is not okay, but the one in this bowl is. The water in the basin has been added with something purified from that stone, which is saltpeter. So the ice formed from that water is not edible. But the water in this small bowl has no saltpeter added. It is formed purely by low temperature, so it is edible."
Meng Yuqing put the bowl back into the basin and continued, "Later, we'll take some fruit, cut it up, put it in the bowl, and then put it in this basin. Cover it with thick animal skin, and we can enjoy the chilled fruit!"
!!!
"I'll get the fruit right away!" Lian immediately stood up and ran towards the crowd.
"I'll go get the animal skins." Yaye said as he stood up.
Saltpeter can be reused to make ice. When Xuan comes back, he will show him how to make it. Xuan will definitely be surprised.
When Ya and Lian came back, Lian was holding several small bowls filled with cut fruits, and Ya was holding a particularly thick animal skin, which was obviously for winter wear.
Under Meng Yuqing's guidance, they placed the small bowl in place and then covered it tightly with animal skin.
The three of them stayed by the ice basin until night fell.
During the process, Meng Yuqing used nitrate to make several basins of ice to ensure that the fruits would always have ice to keep them at a low temperature.
Seeing that those who had gone out were gradually returning, Meng Yuqing lifted the hide, picked up a bowl of fruit that had been chilled to the bone, and said to Lian and Ya, "I'll take this bowl. You two can divide the rest among yourselves."
After saying that, without waiting for the two men to reply, he picked up the stone jar filled with saltpeter with his other hand and ran straight towards Xuan.
Lian and Fang looked at each other and shrugged.
Someone is back, so I don’t have time to deal with them.
When Meng Yuqing ran to Xuan with something in his arms, Xuan was also looking for him.
