After being stranded on a deserted island, they all plotted against me

It is said that in ancient times, people would soak wood ash and then bake it into cement.

With the idea of ​​giving it a try anyway.

Zhang Liu picked up another small clay jar from next to bamboo house No. 3, and then divided half of the wood ash into it. He planned to do the experiment in two batches.

The first time was to try adding water, and the second time was to put it directly on fire.

After adding water.

The wood ash, which was originally in the form of white fine powder, suddenly turned into a mixed soup.

And there is a layer of black stuff floating on top.

He patted the remaining wood ash on his hands.

Remembering what Qin Ruoyan had told him about the "Water Flying Method", Zhang Liu decisively poured the top layer of stuff outside bamboo house No. 3.

These things are most likely impurities. After all, wood ash, as the name suggests, should turn into ash powder that can be used to suspend liquid.

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

It just so happened that the two stone bricks in bamboo house No. 3 had already been fired.

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

When pouring out the black layer on top, Zhang Liu also poured out two-thirds of the gray liquid in the small jar.

Stirring it repeatedly with his hands, he not only felt the sticky feeling of the wood ash after it came into contact with water, but also a slight burning sensation.

The chemical formula of wood 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.

Currently, the knowledge Zhang Liu possesses is only enough for him to complete the formula conversion, and he is not able to use it freely.

Stir for a while and make sure there are no large particles in it.

Zhang Liu also withdrew his hand.

Looking at the wood 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 could replace cement, Zhang Liu didn’t think it had anything to do with cement...

Because even if you burn potassium carbonate dodecahydrate directly to dryness, it will form anhydrous potassium carbonate.

Then heat it by burning.

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 order to give it a try, he poured out some of the water from the wood ash that had already settled.

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

When he was carrying a plate of wood ash and preparing to go to bamboo house No. 2 to make a fire to burn it, 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 saw Anya being hugged tightly by Zhou Fang and Song Shuyao sitting on the bed with her head down and not speaking, but still holding her wolfskin coat in her hand.

The other girls just stood there at a loss as to what to do.

The moment they saw Zhang Liu coming in, Song Shuyao cried, and Anya also cried.

Seeing this scene, his brain, which was able to quickly convert chemical equations, instantly went numb...

………………………………………………………………Dividing line

PS·Here is the toilet drawing that I forgot to put in the last chapter.


In addition, there are only 8,000 words updated today because I was called to work in the afternoon.

This chapter is the last one.

The author will take a day off tomorrow and will try his best to complete it.

Chapter 190 Why is she in your room?

"It seems like An Ya and Shu Yao had a quarrel."

After seeing Zhang Liu coming in, Zhou Fang tried to persuade them to stop fighting, but it could only temporarily stop the conflict between the two sides. She could not end the situation and said helplessly:

"My advice just now was useless, so how about you try to persuade him?"

"Uh..." Holding the ball of wood ash and cement in his hand, Zhang Liu's face was full of helplessness.

Although his brain was numb just now.

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

This is not "as if there was a quarrel".

It's clearly "almost a fight" okay!

However, Zhang Liu also had some understanding of the situation.

There are two main reasons for this.

The first point is that Anya still cares about what Song Shuyao had done to her.

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

When these two points are combined, conflicts naturally break out.

After figuring out the whole thing, he suddenly felt secretly guilty.

Because Zhang Liu also understood that he was at least 70% responsible for this situation.

As long as Song Shuyao is woken up.

Or take away the wolfskin coat.

This situation will not happen now.

Looking at Song Shuyao who was sobbing with her head down and Anya who was standing with tears in her eyes.

Feeling a headache, he turned to Zhou Fang and the others and said, "Well, Mr. Zhou, you guys go out first. I'll try to persuade them alone."

No one said a word.

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

Looking at the rain outside.

They also gave up the idea of ​​building a bamboo house and turned to weaving branch fences at bamboo house No. 3.

However, the four girls' attention was focused on bamboo house No. 2.

There is a feeling of curiosity as well as worry.

And deep down in my heart, there is an expectation.

Zhou Fang and others were actually looking forward to Zhang Liu's subsequent handling methods.

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

"Well, why don't you stop crying?" In the second bamboo house, Zhang Liu walked to Anya's side according to his experience of coaxing his sister, held her little hand, and said softly: "Your eyes are swollen."

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

Then she protested while crying, "Don't look down on my swollen eyes!"

Faced with such a situation, Zhang Liu could only open his mouth in shock.

He had never expected Anya to respond like this.

In fact, this is not the first time that Zhang Liu has encountered conflicts between girls.

Because he has two younger sisters.

The two of them would occasionally start bizarre arguments about who gave their brother a more comfortable back pat or who had bigger breasts and a rounder butt and was more suitable for having children...

The final result was that they took off their clothes and showed off their bodies in front of their brothers. Zhang Liu remembered that once the two idiot sisters were ready to take off their underwear and expose their buttocks to compete for their respective "channel advantages"

But later he gave me a severe "sex education" and told me not to compare this in front of the opposite sex!

However, during this period, Zhang Liu also discovered it.

Whenever he said their eyes were swollen, the two sisters would stop crying immediately and start rubbing their eyes to recover.

This can eliminate a dispute.

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

Zhang Liu's trick, which had always worked, was no longer useful.

I heard Anya's crying getting even louder.

Song Shuyao also felt sad from the bottom of her heart.

She finally managed to ease the tension between herself and Zhang Liu.

The two also chatted and talked together.

They even sat on the same bed.

But now that Anya has cried like this, Song Shuyao doesn’t dare to think about what Zhang Liu’s attitude towards her will be in the future.

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

Biting her lips hard, Song Shuyao used the severe pain to stop her tears, then quietly got out of bed and walked towards Zhang Liu.

These few short steps were extremely difficult for her.

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

Hearing her apology, Anya turned around.

She didn't intend to pay any attention to this girl who was acting like a fool.

Watch this scene.

Song Shuyao's heart, which had already been chilled, became even colder.

She even felt a little desperate.

Facing Song Shuyao's apology again.

Zhang Liu was also helpless.

He never really cared about this matter.

Why do the girls around me care so much?

This is Anya's situation right now.

Qin Ruoyan and Xiang Wanying were bullied by me before and begged for mercy. They gritted their teeth and said that they must get back at the Song family to avenge their men...

"Hey……"

Thinking of this, Zhang Liu also sighed deeply.

Then Anya, thinking that he was already unhappy, immediately stopped crying.
