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

In the end, Xiang Wanying silently rejected this approach.

It's better not to take risks yourself.

"Forget it, let's make a little more and then take it back together to show Qin Ruoyan?"

Looking around, she quickly found her target.

Plantain bushes growing in muddy areas next to rivers

After clearing her throat, Xiang Wanying put forward her idea to Zhao Yiran: "Leave the job of chopping wood to me. Wrap more of this stuff in banana leaves. Maybe it is the food that the wild boars are eating."

"it is good!"

Zhao Yiran nodded quite seriously, turned around and ran towards the banana forest.

After she left, Xiang Wanying continued to wave the metal piece in her hand and began to chop down the two-meter-long bush in front of her.

Although the alloy blade is not sharp, it is still no problem when used to cut down such shrubs.

So when Zhao Yiran wrapped a dozen "suspected sweet potato" roots in banana leaves, Xiang Wanying had already cut down thirteen shrubs.

Later, with the help of Zhao Yiran, the 24 shrubs used to build the basic framework of the shelter were prepared.

Carrying the four shrubs used to build the fire shelter, Xiang Wanying and Zhao Yiran ran to Qin Ruoshuang, who had successfully cleared a three-meter-long open space.

After briefly talking to each other about their discovery, the two began to build a rainproof shelter.

"Is this a sweet potato?"

After hearing about the situation, Qin Ruoshuang was full of curiosity and wanted to try some...

But now that her sister Qin Ruoyan is away, she also doesn't dare to talk casually.

I looked at these roots covered with wet mud for a while.

In the end, Qin Ruoshuang chose to run in the direction Xiang Wanying said to get the bush.

When the fire shelter was built, the three began to build the shelter.

Qin Ruoyan, who had gone all the way to collect flowers, also came back with a handful of purple-calyx-colored flowers.

She collected a lot of purple flowers on a meadow.

This wild vegetable that looks like a flower can be blanched briefly in boiling water and eaten directly.

Qin Ruoyan was very happy to be able to harvest this thing.

At the same time, she also found a lot of closed flowers that fell on the ground.

There are many seeds inside.

in other words.

This thing can be taken back to the taro field to observe and plant.

But after walking to the camp where the fire was already lit.

Qin Ruoyan heard the good news from Xiang Wanying and others who were working together to build a second shelter that they had found sweet potato rhizomes.

"let me see!"

Arranging her sister to start boiling water to blanch the diced purple orchids, Qin Ruoyan turned around and looked at the "sweet potatoes" she had found.

But the more she looked, the tighter her brows became.

When the four members of Xiang Wanying's exploration team finished building the shelter and began to hide inside, waiting for Qin Ruoyan to make a judgment on the rhizome that was suspected to be a sweet potato, Gu Xixi had already crossed the ridge area of ​​the goat jungle with a book basket on her back, and then entered the front area of ​​the jungle. .

Moving forward, her goal was to cross the jungle and enter Shelter No. [-] inside the forest to look for other traces.

After all, if the godmother and Miss Lan Yueting had not arrived, then the last ones to use Shelter No. [-] would be herself and Gu Qingrou!

Gu Xixi was going to use this to judge the traces of the two people.

He reached out and touched the roasted taro that his eldest lady would rather go hungry to keep for herself.

Her eyes were extremely determined.

This breakfast that was still warm represented Gu Qingrou's expectations and worries.

The rain kept flowing around the awning overhead, and then plopped against the rain hat above the head.

But Gu Xixi didn't stop at all. She must find a way to pick up her godmother and the eldest lady's classmate!

Time soon came to noon.

When Gu Xixi stopped to eat something, Anya's cheerful voice came from in front of her.

"I will give three to Zhang Liusheng then!"

Anya walked on the grass that had become smooth and easy to walk on. She turned around and spoke with a proud expression on her face.

Behind her were people who looked dissatisfied. Su Yan, who had just expressed her intention to give birth to two children for Zhang Liu, and Lan Yueting, who had just suggested that it would be best to have a girl.

Replenished with energy from eggs, bird meat, snake meat, and coffee, although the three of them were a little tired, they still had enough energy to joke around.

Therefore, Anya's "declaration" of having three children quickly reached the ears of the Gu family's maid.

"Is it Anya!"

But for Gu Xixi right now, having several children is not something that needs attention at all.

The thing that she pays most attention to right now is why she heard this voice.

According to the plan, shouldn't she and Su Yan accompany Zhang Liu and move on?

Gu Xixi's anxious voice passed through the rain curtain and bushes.

It reached the ears of Anya and others about 100 meters away.

"Hey! It's Sister Xixi!"

Following Anya's surprised voice, Su Yan, Lan Yueting and she all quickened their pace.

Soon the four of them successfully met in the jungle.

"Where are godmother and Zhang Liu?"

After seeing Anya, Lan Yueting and Su Yan who were completely fine, Gu Xixi breathed a sigh of relief.

Then she also asked about her godmother and sweetheart.

"Cuckoo..."

Just when Lan Yueting was about to speak, the pheasant stuffed in the book basket behind her suddenly made a sound.

He only ate a little grass tip in the morning, so now he is eager for the other party to let him go and continue to eat something.

"It's a long story. How about we take a break first, have a meal, and then chat while we eat?"

Looking at Gu Xixi who was full of curiosity because of this "coo", Su Yan suggested.

Chapter 321 The goddaughter who can’t understand her godmother

Under Gu Xixi's expectant expression.

In the end, she still didn't eat the two wild beasts that were left walking around on the grass.

Because Anya, Su Yan, and Lan Yueting simultaneously stopped in front of the Gu family maid who was sharpening her knife and wanted to kill two pheasants and beat their teeth for sacrifice, and emphasized the importance of "sustainable development".

But when everyone finished lunch and continued on their way.

Gu Xixi already understood the overall change in the situation.

Zhou Fang and Lan Yueting, who were originally scheduled to come back, became the three in front of them.

But his godmother went on the road alone with Zhang Liu.

This made her feel a little weird.

After all, based on what she had discovered before, Gu Xixi estimated that her godmother was preparing for a round of "old cows eating young grass".

　Thinking of this, the strange feeling in her heart became even more intense.

After all, Zhou Fang always looked capable in front of Gu Xixi.

Previously, she used the excuse of having a relationship with the Gu family's maid to talk about marriage issues with the other party. Zhou Fang's answer was also "For the sake of the family, I am prepared to practice non-marriage."

But now, she has discovered that the other party obviously has a plan.

This made Gu Xixi feel a little confused for a moment.

In essence, she is not opposed to this kind of thing.

but……

After thinking carefully for a long time, Gu Xixi couldn't fully understand such behavior.

after all……

The age gap between the two is also too big.

There is a two or three year age difference between me and Zhang Liu, so we both have to worry about our outlook on life...

This is already ten years old...

Can you all be a mother?

When Gu Xixi, Su Yan, Anya, and Lan Yueting started to head to the hillside of the hill, preparing to meet up with Xiang Lingying, Song Shuyao, and Gu Qingrou who were staying there.

Zhou Fang and Zhang Liu are collecting pyrite next to the pyrite in the middle layer of the forest.

This kind of ore related to volcanic activity is a proper treasure level for them.

Under normal circumstances, it can be understood according to the calcination equation as

《4FeS2+11O2=2Fe2O3+8SO2》

That is, iron oxide and sulfur dioxide are obtained.

But if we can find a way to isolate the air for combustion, then we can change the reaction equation.

"FeS2====Fe+2S"

Iron and sulphur!

The former is a good thing that is necessary to survive here for a long time.

The latter can be combined with saltpeter and charcoal to form gunpowder.

Just burn the charcoal at will.

Saltpeter is more troublesome.

However, Zhang Liu had seen detailed descriptions in Feng Jicai's novella "Cannoning Double Lanterns".

You can wait until the rainy season ends to check this thing next to the toilet or the pig pen or sheep den. There may be something on the edge of the soil.

And later in the chemistry book, Zhang Liu also learned about the origin of "toilet saltpetre".

Nitrates in the soil, that is, ionized nitrate ions, can be absorbed by plants and turned into nitrogen sources to synthesize amino acids and proteins.

When the plant is subsequently eaten, the end metabolite of protein and amino acids, urea, is excreted.

The ammonia obtained after the hydrolysis of urea and the like releases energy when oxidized, and is then converted into an energy source for autotrophic bacteria - nitrifying bacteria.

Finally, under the action of nitrifying bacteria, the final oxidation product of ammonia is nitric acid.

When nitric acid reacts with minerals in the soil, it eventually turns into nitrates, including calcium nitrate, magnesium nitrate, potassium nitrate, sodium nitrate, etc...

Zhang Liu's subsequent reaction is unclear.

But all he needs is nitrate, something that can be used to make gunpowder or ice.

Now the two of them have collected nearly 30 pieces of pyrite and wrapped them in curtain cloth.

During the collection process, Zhang Liu also accidentally knocked off a few large pieces of ore mixed with long strips of green crystalline stone.

He originally thought that this thing, which looked green and sparkling, might have "spokes on it," and he planned to throw it as far as he could.

But after Zhou Fang's subsequent identification, she determined that these should be long strips of emerald ore.

Because Zhou Fang has several long ore decorations like this at home.

And according to her initial judgment.

These emeralds retain their crystal structure and color and look very good.

If it can be perfectly removed and carved, the price may reach hundreds of thousands.
