Da Qin: Me! the Unparalleled Prince, Guarding the Great Wall for 18 Years

Just find two different-sized containers to fit together and fill them with water at the same time.

Then pour the saltpeter into the large container outside,

When saltpeter meets water, it absorbs a lot of heat, instantly making the surrounding temperature very low.

As a result, the water in the small container will quickly drop to the freezing point and then condense into ice cubes.

The above is the procedure of making ice with saltpeter, which is very simple to operate.

Just find two ice containers and some saltpeter.

As for the raw material of saltpeter, it is not difficult for Ying Changying at all.

Previously, the expeditionary army brought back a lot of various ores from Fusang, including a lot of saltpeter.

Ying Changying had already ordered Taishi Ci to send some saltpeter to his house in case of emergency.

After all, Ying Changying has long been produced when the weather is hot,

Use saltpeter to make ice to get some ice cubes to cool off the heat.

I just didn't expect it to come in handy so soon.

Seeing Ying Changying's confident look,

While touching his beard, Wang Ben laughed and joked:

"Haha, since the son is so confident,

Then please, son, give us a show,

The old man really wanted to see how the young master made the ice cubes. "

"Okay, you come with me!"

Ying Changying didn't bother to talk to them, she directly waved at them, then turned and left.

Ying Zheng and the others saw Ying Changying's sworn expression,

He couldn't help but be more puzzled, and followed them one after another.

After that, Ying Changying took Ying Zheng and others around the mansion, and finally came to a remote yard.

The saltpeter that Ying Changying uses to make ice cubes is stored in this yard.

Ying Zheng looked at the desolate yard in front of him, frowned and said:

"Changying, didn't you say you want to make ice cubes? Why did you bring us to this yard?"

Ying Changying waved her hand and said:

"Father, don't be impatient, the tools used by my son to make ice cubes are placed in this yard."

After speaking, Ying Changying ignored their reaction.

He walked directly into the storage room in the yard and came out with a bag of saltpeter.

After finding out the saltpeter,

Ying Changying went to the utility room next door and found two wooden basins, one large and one small.

After Ying Zheng and the others saw this scene, a hint of curiosity flashed across their brows.

Didn't Ying Changying say to make ice?

Why did you suddenly find something so strange?

What exactly is in that bag?

Can these be used to make ice?

For a time, Ying Zheng and others were extremely confused.

Seeing how busy Ying Changying was, she was embarrassed to ask aloud.

After the ice-making tools were ready, in the eyes of everyone's doubts,

Ying Changying put the two tubs together, then grabbed the saltpeter in the bag,

Pour evenly into the large wooden tub outside.

After pouring out the saltpeter, Ying Changying clapped her hands, and then instructed the servants in the mansion:

"Someone, go and fetch two buckets of well water!"

After the servants in the house got the order, they immediately went to draw two buckets of clean well water.

Upon seeing this, Ying Zheng did not hesitate,

Directly pour all the well water into the two wooden basins until the water almost overflows.

"呲呲呲!!"

As soon as the saltpeter in the big wooden basin met the water, it immediately started a chemical reaction, and a thick white smoke came out.

Ying Zheng and the others on the side were shocked when they saw this.

Ying Zheng only felt that the scene in front of him was very bizarre, and couldn't help but ask:
