After living on a desert island, they all plotted evil against me.

It is said that in ancient times, people soaked plant ashes and baked them into cement.

I just want to give it a try anyway.

Picking up another small clay jar from the side of Bamboo House No. [-], Zhang Liu divided half of the plant ash into it. He planned to conduct the experiment in two times.

The first time I tried adding water, the second time I just put it on fire.

After adding water.

The plant ash that was originally a white and fine powder suddenly turned into a mixed soup.

And there's this layer of black stuff floating on top.

He patted the residue of plant ash on his hand.

Remembering what Qin Ruoyan told him about the "Water Flying Technique", Zhang Liu decisively poured the top layer of stuff outside Bamboo House No. [-].

These things are most likely impurities. After all, plant ash, as the name suggests, should be ash that turns into a suspension.

As for whether the test is successful, Zhang Liu plans to use the elimination method.

It happened that the two stone bricks in Bamboo House No. [-] had been fired.

He planned to use them to test the plant ash cement later.

When pouring out the top layer of black stuff, Zhang Liushun also poured out two-thirds of the gray liquid in the small vat.

Stirring it repeatedly with his hands, he not only felt the sticky feel of the plant ash after it met the water, but also a slight burning feeling.

The chemical formula of plant ash is K2CO3, which is potassium carbonate.

This stuff is a strong alkali and will really burn your hands.

At the same time, it is precisely because of this characteristic that it can be used to process pig skin or wolf skin.

As for the changes after adding water...

Zhang Liu simply converted the chemical formula in his mind.

碳酸钾加水的话，应该就是K2CO3+12H2O=K2CO3.12H2O

That is potassium carbonate dodecahydrate.

But what is the use of potassium carbonate dodecahydrate?

He didn't know it himself.

At present, Zhang Liu's knowledge is only enough for him to complete the formula conversion, but he cannot yet use it freely.

Stir for a while and make sure there are no big particles inside.

Zhang Liu also took his hand back.

Looking at the plant ash that had begun to settle in front of him, he began to think about how to burn it into cement.

To be honest, although the documentary video mentioned that it can replace cement, Zhang Liu didn't think this thing had anything to do with cement...

Because even if potassium carbonate dodecahydrate is directly burned to dryness, it will form anhydrous potassium carbonate.

Then heat it by searing.

That should also produce potassium oxide and carbon dioxide.

That is, K2CO3==heating==K2O+CO2↑...

Does potassium oxide have anything to do with cement?

However, in line with the idea of ​​​​treating a dead horse as a living horse, he poured out part of the water from the precipitated plant ash again.

Then Zhang Liu used his experience of playing with mud as a child and began to roll plant ash into balls and put them aside for later use.

When he was carrying a plate of plant ash and preparing to go to Bamboo House No. [-] to light a fire for burning, he heard Anya's voice inside the bamboo house at the door.

"You said Zhang Liu was spineless before, but now you are so close to him!"

"You're just taking advantage!"

"I hate this behavior!"

After Zhang Liu pushed the door open, he happened to see Anya, who was tightly hugged by Zhou Fang, and Song Shuyao, who was sitting on the bed with her head lowered and silent, but still holding her wolfskin coat in her hand.

The other girls stood beside him helplessly.

The moment she saw Zhang Liu come in, Song Shuyao cried, and Anya also cried.

Seeing this scene, his brain, which can quickly convert chemical equations, instantly went numb...

………………………………………………………………Dividing line

PS·Here are the toilet drawings that I forgot to put in the previous chapter.


In addition, there are only [-] words to update today because I was called to work in the afternoon.

This chapter is the last one.

The author is off tomorrow and will work hard to complete it.

Chapter 1 Why is she in your room?

"Anya seems to have had a quarrel with Shuyao."

After seeing Zhang Liu come in, he tried his best to break up the fight, but it could only temporarily stop the conflict between the two parties. Zhou Fang, who could not end the situation, said helplessly:

"My advice just now was of no use, so why don't you come and give me some advice?"

"Uh..." Zhang Liu held a lump of grass and gray cement in his hand, with a helpless expression on his face.

Although his mind was numb just now.

But that doesn’t mean we can’t figure out the situation.

This doesn't mean "there seems to be a quarrel".

It was obviously "almost a fight", okay!

However, Zhang Liu somewhat understood the situation.

There are probably two points.

The first point is that Anya still minds what Song Shuyao once "did" to her.

The second point is that because she was afraid that Song Shuyao would be woken up, she left her wolfskin coat for Song Shuyao to hold, and then Anya felt uncomfortable.

When these two points are added together, conflicts naturally break out.

After figuring out the cause and effect, he suddenly felt secretly guilty.

Because Zhang Liu also understands that there will be such a situation, and he has at least about 70.00% of the responsibility.

Danfan woke up Song Shuyao.

Or take away the wolf fur coat.

This situation will not happen now.

Looking at Song Shuyao, who was sobbing, and Anya, who was standing in tears.

Feeling some pain in his head, he turned around and said to Zhou Fang and others: "Well, Teacher Zhou, please go out first. I will advise you alone."

No conversation was made.

Zhou Fang, who had been persuading for a while but still to no avail, Xiang Lingying, Su Yan, and Gu Qingrou all walked out one after another.

Looking at the rain outside.

They also gave up the idea of ​​building a bamboo house and instead went to Bamboo House No. [-] to weave leaf fences.

It's just that the four women's attention fell on Bamboo House No. [-].

There are feelings of curiosity and thoughts of worry.

And deep inside, there is even more expectation.

Zhou Fang and others were actually looking forward to Zhang Liu's follow-up treatment.

........................

"Well, why don't you stop crying first?" In Bamboo House No. [-], Zhang Liu followed his own experience of coaxing his sister and walked up to Anya, held her little hand, and said softly: "My eyes are swollen."

"My eyes are not swollen!" After hearing this, Anya immediately broke away from Zhang Liu's hand, and then directly covered her cheeks with both hands.

Then she cried and protested: "Don't blame me for having swollen eyes!"

Faced with this situation, Zhang Liu could only open his mouth and show a shocked expression.

He never expected Anya to respond like this.

In fact, this was not the first time Zhang Liu had encountered conflicts between girls.

Because he has two sisters.

The two of them would occasionally start inexplicable arguments over who could give her brother a comfortable blow on his back, or whose breasts and butt were big enough to give birth to a child...

The final result was to take off their clothes and show off each other's figures in front of his brother. Zhang Liu remembered that one time two idiot sisters were going to take off their underwear and expose their butts to compete for their respective "channel advantages."

However, he later gave me a severe "sex education" and told me not to compete in front of the opposite sex!

But during this period, Zhang Liu also discovered it.

As long as he said that his eyes were swollen, the two sisters would immediately stop crying and start rubbing their eyes to recover.

This way a dispute can be eliminated.

However, at this moment, she is facing Anya and Song Shuyao, who are not sisters.

Zhang Liu's tried-and-true trick was useless.

Hearing Anya cry more violently.

Song Shuyao also felt sad in her heart.

She finally had some relaxation with Zhang Liu.

The two also chatted and talked together.

They even sat on the same bed.

But now that Anya had cried like this, Song Shuyao didn't dare to think about what Zhang Liu's attitude would be towards her in the future.

Thinking of this, she felt so regretful that her mouth began to taste bitter.

Biting her lip with all her strength, Song Shuyao used the severe pain to stop her tears, then silently got out of bed and walked towards Zhang Liu.

These short steps were extremely difficult for her.

Standing next to Zhang Liu and Anya, Song Shuyao, holding a wolf fur coat in her hand, said like a child who takes the initiative to admit his mistakes after making a mistake: "Anya, Zhang Liu, I really didn't mean it, I was not sensible at that time..."

Hearing her apology, Anya turned around.

She was not going to pay attention to this girl who had already behaved according to the circumstances.

Watch this scene.

Song Shuyao's heart, which was already cold, became even colder.

She even felt a little desperate.

Faced with Song Shuyao's apology again.

Zhang Liu was also very helpless.

He didn't pay much attention to this matter at all.

Why do the girls around me care so much?

This is what Anya looks like now.

Qin Ruoyan and Xiang Wanying were even bullied by him to the point of begging for mercy. They gritted their teeth and said that they must get this situation back from the Song family to avenge their men...

"Hey……"

Thinking of this, Zhang Liu also sighed deeply.

Then Anya, who thought he was already unhappy, stopped crying immediately.
