The card draw is not ruthless, and the gate of the house is unstable

"No, no, one more sentence!"

"It's a little hot today?"

"That's right, that's it!"

Xie Qingyu was a little excited. Didn't he encounter saltpeter when testing energy before?

She can use this!

Just rounded up the previous excuse.

Thinking of this, Xie Qingyu picked up the bowls and chopsticks and started eating quickly.

She had to study carefully to find out what was the proper ratio of saltpeter to ice.

"I've finished eating. Auntie, you can rest later and don't worry about me."

Xie Qingyu put down the bowl so that Xi Tong wouldn't have to wait for her, then got up and went indoors to study how to make ice with saltpeter.

At that time, they put the stones into the spring, and when they took them out, there was a layer of frost on one of the ores.

At that time, Xie Qingyu guessed that it was saltpeter, but later put it behind him.

Just now Xie Tong said it was hot, Xie Qingyu thought of it now.

She wanted to look for saltpeter before, but she never found it.

In the end, the ice used in the milk tea shop at home is all stored in winter.

If the ratio of ice production is studied, there will be no need to worry about not enough ice cubes in summer in the future.

Because he didn't take out the ore last time, Xie Qingyu went directly to the world of kings.

Just in time to brainstorm.

"Qing Yu is here."

"Sister Qingyu!"

As usual, as soon as Xie Qingyu arrived at the square, everyone in the square greeted her one by one.

After Xie Qingyu responded one by one, he asked about the whereabouts of the ore.

"Sister Qingyu, those stones are still in the spring!"

When Cai Wenji heard Xie Qingyu asking where the previous stone was, she immediately spoke up.

"However, sister Qingyu, what are you doing with the stone?"

Those stones have no energy, so why does Sister Qingyu still look for them!

Xie Qingyu patted Cai Wenji's head, "Do you still remember when we tested before, there was a layer of frost on a certain kind of ore?"

"Mmmmmmm!"

Cai Wenji nodded, "Little Lu Ban and I scraped it off to play with!"

"It's the same as the one transformed by sister Zhaojun, but it's too little..."

Cai Wenji was a little frustrated.

"So, let's make more ice together today, shall we?"

Xie Qingyu raised his hand and touched Cai Wenji's head, and said in a somewhat coaxing tone.

"Can we also make ice?" Cai Wenji wondered.

"Sister Qingyu, have you learned the ice and snow skills of sister Zhaojun?"

Xie Qingyu shook her head, she learned those skills as soon as she said she would learn them.

Instead of using their skills directly as before, they create their own skills.

Seeing Xie Qingyu shaking his head, Cai Wenji suddenly lost interest.

She thought that Xie Qingyu would use ice and snow.

The result is not.

If so, how to make ice.

Seeing Cai Wenji's disappointment, Xie Qingyu smiled, "Although we can't use spells, we can use saltpeter!"

"Nitro?"

"It's the stone that was frosted before." Xie Qingyu nodded, "You can use it to make ice!"

"Ah!" Cai Wenji exclaimed, it turned out that Xie Qingyu was talking about making ice with that stone.

"Then I'll call Little Luban! Last time I played with him on the ice made of stones, it was so much fun!"

As Cai Wenji said, she quickly ran away to find Xiao Luban.

Xie Qingyu didn't follow, nor did he wait in place.

Instead, go to the spring first.

She only has more than an hour, so she has to work it out quickly.

I don't know if it will be successful tonight.

The last time it was placed directly in the spring of the spring, it condensed into frost when it was taken out.

Now, without knowing the proportions, it is up to you to make ice, whether it will go smoothly or not.
