Thinking about all this, she felt a sense of pride and said:

"Little Fish, we haven't done this yet, so let's not make a fuss about it."

Once we've conducted the experiments, produced the product, and confirmed that it works, we'll go down the mountain again.

Anping County is in dire need of reconstruction, not only Anping County, but also the cities you mentioned.

We've rebuilt countless houses. This is the business we've been in.

If things go as expected, as long as we can cooperate with Lord Fang, our county might even benefit from this misfortune and become even better!

Chi Yu is an obedient person, especially to her older sister.

Hearing her instructions, he nodded repeatedly: "Okay, sister, I'll listen to you."

However, from now on, please don't throw away the wood ash in the house.

If possible, please collect some for me in the village.

"Okay, I'll talk to your older brother later, and I'll also let Ah Kang know."

If he could get the old clan chief to collect them, that would be ideal.

Anyway, we can't let Xiaoyu handle these things now.

Everyone is currently indebted to her, so if she asked, everyone would definitely give.

But humans have their flaws!

If you save someone, and they send you wood ash a few times when you need it, they might feel that they are repaying your kindness.

If you offer to buy it, they will initially politely say no, thinking it's useless anyway, so they might as well give it away.

After a few times, things will change, and they will start charging money.

Once they find out what the money is used for, and see you making money, their attitude will change.

Although we are all from the same clan, we shouldn't be talking about gratitude or anything like that.

But Chi Qiao believed that since they had done it, they had to make them remember the debt of gratitude they owed.

Instead of thinking that a mere speck of wood ash is enough, and then getting envious when you make money using their products.

Chi Yu's thoughts were becoming increasingly scattered.

She realized that the water extracted from wood ash could also be used to make soap.

Thinking it over, she asked her sister before she left, "Sister, are there any shellfish in the lake near Tiger Head Cliff?"

Even something like a freshwater clam will do.

We can throw this shell into a charcoal fire and burn it. After it's burned, we can grind it into powder. Its main component is calcium oxide.

This calcium oxide is what I just mentioned, the stuff left after calcining wood ash.

Equivalent to quicklime.

Then, because there was a previous method of extracting alkali from plant ash, which involved boiling plant ash to make soda ash.

After filtering the water, add shell powder and let it sit overnight. Then add rendered and cooled lard, and a little salt.

Upon hearing that salt was being added, Chi Qiao couldn't help but ask, "Why do we need to add salt?"

She was really bad at chemistry in high school, and she would fall asleep whenever she had a chemistry class, so she really didn't know these things.

Even when reading novels with Xiaoyu, whenever these things are mentioned in the novel, she just skims through them and then skips over them, and afterwards she can't remember exactly how to do them.

But she still remembers that the main ingredients used were wood ash and lard.

"Sister, salt is sodium chloride. Adding it helps the water in the soap evaporate, increasing its hardness and durability."

Chi Qiao nodded upon hearing this and said nothing more.

However, she was thinking to herself that she and Xiaoyu had laundry detergent, soap powder, and soap from their space.

It makes washing clothes much more convenient.

However, the people in the tribe still use soapberry or wood ash to wash clothes, which is indeed not very convenient.

If she were to do this business, she would have to go to the county town at the foot of the mountain to investigate whether soap was sold there.
