Huang Tinghui put the filtered plant ash into the iron pot, and then poured a bucket of crystal clear spring water into the iron pot to submerge the plant ash.

"Lian'er, light up the fire!" Huang Tinghui said to the little girl.

After receiving the instruction, the little girl immediately lit the tree sticks on the stove, and the flames sprang up, making a "pop-pop" sound.

Huang Tinghui found a wooden stick to remove the bark. He stirred hard in the iron pot, stirring the plant ash in the iron pot evenly.

The little girl kept adding firewood to the stove, and the flames were burning brighter and brighter.

A pot of plant ash solution was boiled by the fierce fire. Huang Tinghui let the plant ash solution boil for a while before letting the little girl take out the burning sticks from the stove.

"Brother Tinghui, what are we going to do next?" the little girl asked extremely curiously.

"Next, we are going to reclaim wasteland, we have to remove weeds, and we don't have much firewood at home. I have to go to the mountains to get some firewood!" Huang Tinghui arranged what to do next in just a few words.

It's all properly posted.

"Ah?" The little girl looked at Huang Tinghui blankly. He did not expect Huang Tinghui to give such an answer.

"Hahaha..." Huang Tinghui laughed loudly. He didn't explain to the little girl. He took some tools and walked straight out.

There is no way, I can’t explain these clearly!

Huang Tinghui did this just to obtain some highly concentrated lye. The plant ash needs to be left for a period of time to obtain highly concentrated lye.

When explaining this matter to the little girl, it seemed that it was not clear for a while. After all, there was a lot of knowledge in junior high school chemistry textbooks.

The little girl glanced at the stove and then at Huang Tinghui's back.

She put the pot lid on top of the plant ash solution, and then used the lid of the pottery pot to cover the pottery pot filled with lard.

After doing all this, the little girl took the farm tools and started her hard work again.

Some vegetable seeds suitable for winter were carefully sown by the little girl on the newly reclaimed wasteland.

The little girl turned over the loose and warm soil and pressed it on top of the vegetable seeds.

In this way, he and Huang Tinghui can eat fresh vegetables in winter.

After doing all this, the sun had already set in the west, and the little girl's stomach growled twice. Only then did she realize that the sky was getting a little dark.

In ancient times, people usually only had two meals, and the same was true for the little girl and Huang Tinghui. It was quite difficult for Huang Tinghui to adapt at first.

But after several hungry meals, everything was no longer a problem.

Seeing that the sky was getting dark, the little girl looked toward the mountains and fields.

Sure enough, she saw the shadow of a man carrying a lot of firewood walking slowly towards the setting sun.

The little girl smiled sweetly. This was something she had never dared to imagine even in her dreams.

But now everything has become true!

If you can spend your whole life in such an ordinary way, it will be worth it, the little girl thought.

"Brother Tinghui!" the little girl waved to Huang Tinghui in the distance.

Huang Tinghui walked a few steps and soon came to the dilapidated thatched house. The little girl quickly opened the fence in front of the thatched house and let Huang Tinghui walk in.

"Lian'er, it's almost time, let's go to the kitchen to take a look!" Huang Tinghui rubbed the little girl's head, and the two of them walked into the kitchen.

Putting the bundled firewood aside, Huang Tinghui couldn't wait to open the lid of the iron pot.

The light yellow liquid appeared in front of Huang Tinghui, and a smile appeared on Huang Tinghui's face.

This is what Huang Tinghui wants!

Use lye obtained from plant ash, add lard and cook together until the fat is completely dissolved.

When the time comes, keep stirring and heating until more than half of the water has evaporated, then add a little salt cubes to it.

This is the finished product that Huang Tinghui finally wants to get.

"Brother Tinghui, is this okay?" the little girl asked anxiously.

She seems to be more nervous than Huang Tinghui.

"Okay, let's watch brother Tinghui do tricks next!"

"Lian'er, please light the fire. My brother wants you to keep the fire burning brightly." Huang Tinghui said to the little girl with a smile.

The little girl nodded when she heard this, and hurriedly lit the dry wood on the stove with a fire stick.

The flames immediately started and the stove was heated up immediately.

Huang Tinghui found a spoon, scooped out the lard from the clay pot, and placed each piece into the plant ash solution in the iron pot.

In a high-temperature heating environment, lard dissolves quickly.

The alkaline solution and lard were perfectly blended together. Huang Tinghui took a wooden stick and kept stirring the two solutions in the iron pot.

I don't know how long it took, but it wasn't until more than half of the water in the pot was reduced that Huang Tinghui put down the wooden stick in his hand.

It's almost done at this point.

Huang Tinghui grabbed two pieces of crushed salt and carefully sprinkled them evenly into the iron pot.

Watching Huang Tinghui sprinkle the salt into the solution, the little girl felt extremely distressed.

In this era of salt and iron government management, the price of salt is expensive.

The little girl usually eats a little bit of salt carefully, but now seeing Huang Tinghui spreading salt into the milky white solution, it is inevitable that she will feel a little distressed.

However, the little girl feels distressed, but she has no principles or reasons to support anything brother Tinghui does.

Watch the plant ash and lard mixed together, plus a little salt, to create the final product.

The little girl couldn't help but widen her eyes.

I'm afraid I missed something.

At this time, Huang Tinghui walked inside the thatched house and found some wooden molds that he had polished before.

Then he poured the milky white solution into the wooden mold, and Huang Tinghui's task was completed.

Next, all Huang Tinghui needs to do is wait.

After these milky white solutions cooled and solidified, it was what Huang Tinghui wanted to get.

"Brother Tinghui, what is this?" The little girl looked at the solution in the mold with gleaming eyes. Like a curious baby, she looked at Huang Tinghui and asked.

"In the future, you can use these things when you wash clothes and take a shower. These things are very effective at removing stains!"

"You can wash clothes and take a shower clean!" Huang Tinghui explained with a smile.

When the little girl heard this, her eyes lit up even more.

No wonder brother Tinghui said he could exchange money, so it turned out to be the case.

Who would say no to something that can be washed cleanly by washing clothes or taking a shower?

"Brother Tinghui, what's the name of this thing?" the little girl asked again.

"Let's call this thing soap!" Huang Tinghui smiled slightly and said to the little girl.
