Heishi still felt that it was a good thing to gain more. When he arrived at the waterside, he was in a hurry to pick a place to dig a water hole.

"Don't be anxious, catch some fish first." After all, I exchanged work with the tribe. Is it better to cook things and eat these things? It's better for Black Stone to make it? It's not easy to see it and gossip: "The mold is not difficult to make, don't rush it like this. You cook breakfast first, let's eat it and take your time."

Hei Shi didn't even have some room for imagination, so of course he could only say what Xia Weiwei said. Xia Weiwei sorted out soft velvet grass when Black Stone picked fish, and sorted out soft velvet grass when Black Stone handled fish meat. When he lit the fire, he still sorted out soft velvet grass.

Seeing that Heishi poured the water into the pot and was not busy laying the fish, but instead washed the lotus roots. Xia Weiwei hurriedly shouted: "Give the fish first, the fish will be cooked later. The lotus roots will be eaten after boiling, so don't worry."

He was not as familiar with cooking things as Xia Weiwei. He raised the ceramic basin and put the fish into the pot after hearing the sound.

The fish meat was poured into the pot, and Heishi wanted to cut lotus roots again. Xia Weiwei thought about it and said again: "The cut of the lotus root will be black. You have to make some water to soak the cut lotus root segments."

"What if I cut it later?" Blackstone paused.

He stood up and brought a bundle of soft velvet grass. Xia Weiwei then said: "If the fish is to be cooked, just cut it and throw it into the pot. If you have to wait a while before putting it in the pot, it is better to soak it in water."

"?"

Facing the question marks that were full of black stone, Xia Weiwei was not annoyed. While unbuttoning the straw rope that bound the soft velvet grass, she explained: "Starry will have an effect on the air. Freshly exposed starch will oxidize after contacting the air for a long time and will turn black. Although the oxidation of a small amount of starch is harmless to the human body, it doesn't matter if it is eaten, but it's uncomfortable to look black."

Lotus root powder is starch. He already knows this. He doesn’t understand why air affects starch. Similarly, he doesn’t understand what oxidation means.

He stared at the thin girl who was wearing a calm face but quick eyes and hands, and quickly sorted out the soft velvet grass for a moment. Black Stone said "Oh": "Then I'll dig a hole first?"

Heishi didn't know what Xia Weiwei called "dream". Adding the reason why the lotus root was a squid and "telled" her. Xia Weiwei's series of words, Heishi naturally thought of it on the squid.

For Black Stone, the squid is the same as the Aoki.

No matter how incredible what Juan Wu said, he would not doubt it.

Unexpectedly, Hei Shi thought a lot in an instant, but Xia Weiwei was a little surprised if he didn't see him digging his roots.

When he met Xia Weiwei's exploring eyes, Hei Shi raised his eyebrows: "What's wrong?"

"···No." Because he couldn't understand, it would be better not to ask: "Don't go far, just dig here."

Hei Shi opened his mouth and wanted to say something, but he nodded after looking at the stove: "Yes."

Knowing that red paste mud is useful, Black Stone is very careful when digging red paste mud, and no impurities can be confused. Because he climbs up the slope from time to time to add fuel, the puddle is digging relatively large. When a puddle is dug, the lotus root and fish soup will be served for a while.

The lotus root is slightly cut by Xia Wei, and she carried it to the side when the fish soup is cooked.

Hei Shi moved the new mud dug to the side of the pile of mud where there was not much red paste, and then washed his hands and had breakfast.

The two of them ate and worked their own things silently. By noon, Black Stone dug out six puddles with a diameter of two meters and a depth of one meter five meters, while Xia Weiwei completed two straw coats.

Standing up, stretched his lower limbs, Xia Wei snorted: "Your hot fish soup, I'll go in and see Aunt Huang Tao's mother and daughter."

He looked up subconsciously and then realized that it was already noon.

Frowning, he nodded: "I understand."

The situation of Huang Tao and his daughter was getting better every day. Xia Weiwei came out shortly after she went in. While Xia Weiwei was in, Heishi not only heated the fish soup, but also pulled out a lot of taro.

"Is it enough?" asked Black Stone.

Staring at the huge pile of taro beside the fire, Xia Weiwei nodded silently.

Not only is it enough to test, even saponin should be able to be refined.

By the way, she chose this place and seemed to have more taro bushes than other places!

His eyes turned to the taro bushes on the slope and retracted them. Xia Weiwei took the small bowl handed over by Heishi and squatted down: "Put too much taro roots, so there is no need to poison, and the fish may die of hypoxia."

"Deficiency of oxygen." The bowl delivered to the mouth was paused for a moment.

This is the second time I have heard this word today.

Although curious, Black did not mean to ask.

He was not sure whether Xia Weiwei knew the meaning of these two words.

When she lifted her eyelids, she saw Hei Shi snoring and drinking soup, waiting for her to explain, Xia Weiwei couldn't help but wonder: "Don't you want to know what oxygen is? What is hypoxia?"

"···Do you know?" Without even lifting his eyelids, he scooped up the lotus root after swallowing the soup.

Xia Weiwei: "·····"

After that, I felt that she didn't know!

Do she want to thank him for his understanding?

"After all, I'm the one who grew up watching me. I think you are more reliable than me, what he does?" For the first time, Hei Shi's words brought resentment: "If he knew about you, he would definitely regret it."

Xia Weiwei: "·····"

She couldn't say that these things had nothing to do with the great uncle in his heart. The stupid girl in his eyes was really bullied to death by that family!

Directly, Xia Weiwei pretended that she hadn't heard Hei Shi's complaints, and buryed herself, and gave him some popular science: "All animals need oxygen. Although fish and humans are very different, fish, like us humans, also need oxygen to survive."

"Fish gills are a very special filtering system. They can filter the oxygen contained in the water. Therefore, when raising fish, the size of the fish pond, the amount of water in the fish pond, and whether the pond water is flowing live water is important..."

Honey, Xia Weiwei explained what oxygen is and what hypoxia is in one breath.

Originally, Hei Shi was still eating, but as he listened, his movements slowed down. At the end, he stopped moving.

When he was sure that Xia Weiwei would not say anything, he asked: "What do you mean is that as long as the water contains enough oxygen, the fish will not die?"

"No, I mean, the oxygen in the water is enough for the fish to survive." After Gugud drank half a bowl of fish soup, Xia Weiwei continued: "Fishes also need to eat food, and they will starve to death without food."

Heishi didn't know what he thought of, but he was silent for a while. Then, his legs and feet were hard, and he turned directly from the other side of the fire to Xia Weiwei: "If the water has enough oxygen and enough food, will the fish I put down this year be good next year?"

The word "未分" does not exist at all for primitive people. Hei Shi's question really surprised Xia Weiwei.

Seeing Xia Weiwei looking at him incredibly surprised, Heishi looked solemn: "Your father wants you to think more, why do you only think of taro roots?"

Xia Weiwei: "·····"

Blame me?
