The Beauty of the World: The Peerless Female Army

Chapter 235
"Oh, I understand! Tomorrow I will order that the soldiers guarding the city will allocate [-]% to go out to find these places, and collect all the soil from those places and hand them over to you for you to check. What do you think?" Xueyi pondered for a moment, then whispered in my ear.

I was taken aback for a moment, but I have to say that this is much faster than blindly looking for it by myself.

"This kind of soil nitrate is often associated with saline soil, and it is the product of the upper layer of black soil in low-lying areas. Its color is yellow, its taste is bitter, and its quality is light. Let them look for it in some caves! And, let each of them Put all the soil in a bag, write their names on the bag, and where the soil they sent up was collected!" In this way, if I can find the soil, I will know where they found it at once of.It would be great if you could find large patches of soil nitrate.

"En!" Xueyi nodded, then asked again suddenly: "What do you want this soil salt for?"

What are you doing?Of course it is very useful.However, I haven't found it yet, and I don't know if I can make it successfully, so I am not going to tell him yet, so I said: "I have my own use!"

Seeing what I said, Xueyi knew that I didn't want to say any more, so she didn't ask any more questions, and hugged me and fell asleep.

As the saying goes, "There is great power in numbers!" This sentence is not wrong at all.Since the afternoon of the second day, people have been sending some soil to me.And since this afternoon, I have been identifying the soil.

But after ten days of busy work, there is no progress at all!I can't help but feel a little discouraged!

However, Xueyi didn't seem to lose confidence, and a large number of soil samples were still sent to me every day.Looking at the soil samples sent in every day, although I was a little discouraged, I still cheered up and analyzed them one by one.I hope the next one can surprise me, however, what I waited for was disappointment again and again.

No. On the 12th day, when I opened a piece of soil in a blue cloth bag listlessly, I saw that the soil contained in it was a little yellowish. I smelled it with my nose, and then picked it up with my hand to identify it carefully , I'm initially sure, this is what I'm looking for.

Suppressing my excitement, I took that portion of soil and did another experiment, and the result proved that my conclusion was correct, that was indeed the soil salt I was looking for, that is, potassium nitrate.

After looking at the name on the bag and the place where he collected it, I plan to let this person come to see me tomorrow morning, and then take me to the place where he found the soil nitrate to investigate...
