Ye Qing decided that if he found that there was nothing abnormal about Xiao Tangyuan in the future, he would keep the two pandas outside.

At this time, Zhou Yaozu came over, followed by several servants, each with an iron box in his hand.

"Mrs. Qian, the iron box you want has been made, can you see if you are satisfied?" Zhou Yaozu asked.

Ye Qing walked over and looked at the box in their hands, picked up a small one and looked at it at the sun, "Yes, you move these to a shady place, and then go pick up a few buckets of water." ”

"Did you hear that? Do as Mrs. Qian says. Zhou Yaozu shouted loudly.

"Yes." A few servants put down the box and went to fetch water quickly.

It didn't take long for all five loads of water to be picked up.

"Lady, what are you going to do?" Qian Junbao asked curiously looking at the water and the box.

"Make ice." Ye Qing whispered to him.

Qian Junbao nodded, not very surprised. He also knew Ye Qing's origin, and there was nothing strange about being able to make ice, but because he hadn't seen it, he was still very curious.

"I'll come right over." As soon as the words fell, Ye Qing entered the outhouse and quickly took out a jar of things.

Ye Qing first put half of the water in a small iron box, and then scooped out some white things from the jar and poured them into the big box.

Immediately afterward, she added some water to the large box.

Soon all five sets of boxes were made by her.

Zhou Yaozu looked stunned, he didn't understand what this had to do with curing, and couldn't help asking, "Mrs. Qian, what are you going to do?" ”

"Make ice cubes." Ye Qing raised his head and smiled.

"So you can make ice cubes?" Zhou Yaozu's eyes widened in surprise.

"Of course, you'll see it soon." What she just added to the big box was something for ice cubes.

If it weren't for the fear that the ancients would be too conservative, she would have taken an ice machine out and used it.

The one that Ye Qing poured in is called saltpeter, and when it is dissolved in water, it will absorb heat and reduce the temperature, so the water in the small box will freeze.

Spent 10,000 gold coins in exchange for a ton of the best white saltpeter, this thing can be used again and again, and one kilogram can make ice bricks one meter long and half a meter high.

And this is not a loss, it can be used next time, and it will not consume too much saltpeter to make a ton of ice, which is still very cost-effective.

If it weren't for the fact that the space store would cost at least 10,000 gold coins, Ye Qing actually didn't want to exchange so much saltpeter.

However, she has already redeemed an ice machine in the space, which is a good thing she will use to make cold drinks in the future.

"Look...... There was a fog coming out. Lan'er pointed to the big box and shouted in surprise.

Others also noticed this, Zhou Yaozu touched the big iron box with his hand, and immediately gasped, and sure enough, it became cold.

Ye Qing thought about it, and poured some powder into each big iron box, and soon the water began to freeze, and after a while, thin ice flakes slowly began to appear on the water in the small basin.

"Really turned into ice?" The people surrounding the iron box were all stunned when they saw such a magical sight, they didn't expect Bing to be able to do this.

Qian Junbao also looked at Ye Qing with some surprise, were these things really left by her master?

How can a nun have something magical that is not in this world?

My own lady is really getting more and more mysterious.

However, Zhou Yaozu's mind was all white things that Ye Qing had put into the big box before.

"It's amazing." Someone lamented.

"I've opened my eyes!" Zhou Yaozu poked the ice with his finger with a look of surprise, and while exclaiming, his eyes rolled and asked, "What did you put in just now?" ”

"That's what my master gave me, so I can't tell you." Ye Qing said lightly.

Her master?

With such means, it is possible to turn water into ice.

It seems that Ye Qing's master is really a fairy-like figure, he has received news of his sister's illness last night, and nothing happened to his sister, and she slept peacefully.

After a while, it is estimated that she will be able to wake up, if that is the case, it means that Ye Qingzhen has cured her sister.

That Ye Qing is the person he wants to try his best to woo, not to mention that there is also a Qian Junbao.

"If so, what if the old man spends money to buy it?" Zhou Yaozu glanced at Ye Qing with his eyes.

"A tael of snow crystals sells for a tael of silver, and a catty can make two thousand catties of ice. Are you going to buy it? Ye Qing asked with a smile.

A ton of saltpeter cost her 10,000 gold coins, and if it were normal, 10,000 taels of silver would be exchanged for 10,000 gold coins.

Therefore, the cost of one kilogram is almost one tael of silver, and in ancient times, it was sixteen taels for one catty, and it is natural to sell it to Master Zhou to double it.

Zhou Yaozu was stunned, two thousand catties of ice cost ten taels of silver, and the ice shop outside sold ten cents a pound of ice.

Two thousand catties of ice cubes are 20,000 yuan, which is equal to twenty taels of silver, this transaction is simply a huge profit? !

And with this thing, you can make ice whenever you want, which is very convenient.

It's a good deal, it's a good deal.

"It turns out that this is called snow crystal, I don't know, can this ice cube be edible?" Zhou Yaozu asked.

Ye Qing nodded and said, "As long as the water in the small basin is drinkable, the ice cubes made can be eaten." ”

"That'...... I wonder how many of those snow crystals you have? Zhou Yaozu asked again.

"Well, there are more than a dozen pounds." Ye Qing didn't say much, scarcity is expensive!

Zhou Yaozu nodded and said, "Okay, can you sell the old man ten catties, if there is still an old man in the future, he will also buy a large number of them." ”

Ye Qing was silent for a while and said, "I can sell you ten catties of snow crystals, but that's all for the time being, I will tell you again if there is goods in the future." ”

Although she has so much saltpeter, she still has to use it herself, and she doesn't want to sell it all to Zhou Yaozu.

She can keep half of it herself and use half of it to make ice for sale, and she has to use ice to make something more valuable.

The saltpeter in her hand was a purified white crystal, and the ancients couldn't recognize what it was.

Even if they know that this is saltpeter in the future, it is estimated that it will take a while, and the saltpeter taken by the soil method may not necessarily be able to make ice in large quantities.

Thinking that this was also a way to make money, a hint of a smile appeared on Ye Qing's lowered face.

But she didn't plan to make money from this thing all the time, if the streets were full of ice, then the ice cubes in the ancient summer would be worthless.

In ancient times, there were actually too many things that could be done, but many of them required a powerful background to spread the things in their hands all over the world.

Otherwise, it will attract coveted traitors, and she doesn't have that much ability at the moment, so she can only spend more time saving gold coins and upgrading the space to obtain stronger abilities.

It's not realistic to eat a big fat man in one bite, and you may be killed by someone as a pig.

The truth of guilt is universal in any world, a lonely and helpless child holding a gold brick in his hand, is a bad person who wants to rob it.
