The rain outside the cave was very heavy, and the wind was blowing fiercely, which can be said to be the world has lost color, but inside the cave is very warm.

Ah Yu looked at Mu Tong, who was concentrating on nibbling on chicken wings, and a smile hung on the corner of his mouth. These days, the relationship between him and Mu Tong has long changed from strangers to family, although Mu Tong is not as sweet to him as he was with Shen Kai, but he believes that over time, Mu Tong will treat him differently.

Anyway, it is a fact that he and Shen Kai are now sharing the same body. Shen Kai is intimate with Mu Tong, how can he not feel it at all? He just can't dominate, so he doesn't say anything. Thinking of the spring at that time, Ah Yu's face couldn't help but turn red again.

He couldn't understand the conversation between Shen Kai and Mu Tong, he heard that it was in the dialect of their hometown. But between Shen Kai and him, he can communicate with his heart.

What Shen Kai told him, he believed it, after all, two souls were in the same body, wouldn't it hurt the two of them to say that he was panicking?

Therefore, for Mu Tong's special storage space, Ah Yu did not say anything to outsiders. This is the wife's secret, the secret of their family. Now, the prey he hunts every day, as long as he can't eat it that day, puts it in that place. Anyway, there are a lot of prey now, and he has the strength to go out and fight every day.

Food is stored every day, and by the long winter, they will not go hungry.

Mu Tong finished gnawing on the two chicken wings, and Ah Yu handed her the two wings of the other chicken and a chicken leg. Mu Tong's appetite is not as good as that of the two brothers, Ah Yu knows it, and after seeing her take it, he took the rest of the chicken in his hand and ate it.

After eating the chicken legs, Mu Tong took out a few more washed blue strawberries to eat, of course, she also took a few for Ah Yu and put them in a stone bowl. In a stone cup, he poured a cup of water that had been boiled and stored a long time ago, and handed it to Ayu.

The summer rain comes and goes as fast as it comes. Don't look at this as an otherworld, the general direction is still the same. Therefore, when the two of them ate and drank about the same, the sky outside was also clear.

Carrying two empty baskets on their backs, the two of them got out of the cave and began to walk in the direction of the tribe, and now they go back, plus the collection along the way, it is almost evening to return to the tribe. Walking all the way to the tribe, these two baskets are also full.

Mu Tong accepted some of the rings and took out some newly discovered ingredients: sweetheart fruits, dough leaves, and a variety of spices and spices.

I took out some of each, and I had to let the people in the tribe know about them. When you know and know the use, you will collect it and make good use of it.

Ah Yu went to the wizard's house first with a full load of belongings, and only after teaching the wizard and his apprentices to know these plants, and then leaving some samples of each of them, Ah Yu returned to his thatched hut.

From a distance, I saw Mu Tong, who went home first, and Dorjee and Dorjee were drying something on the clothesline in the yard. When I got closer, it turned out that I was drying a freshly washed quilt and other things.

"Okay, why did you wash it?" Ah Yu is puzzled, these things haven't slept for a few days, where are they dirty?

"Brother, the house is leaking, and the quilt is wet, so my sister-in-law washed it." Dorjee looked back at the roof made of grass, and his face was full of sadness: every year when it rains in summer, every house is like this, it rains heavily outside, and it rains lightly inside.

His house is good, and the roof is very thick, so it is not easy to leak. Like other people's houses, some of them are easy to make the top of the house thinner, and I don't know what the leakage has become.

Mu Tong looked at the grass house and sighed: It seems that the construction of the house has to be advanced. Otherwise, would it be like this all summer?

From the mouths of the two brothers, I learned that not only does it rain heavily in summer, but also the Chishui River in Gukou has to send a big flood every year. Every time there was a big flood, the whole tribe would be drowned. All the people who fell behind would move to a nearby cave and then move back when the water receded.

Clean up the silt or something, repair the roof and walls, and live in it again.

Mu Tong stuck out his tongue: Just this grass and mud wall, can it withstand a few days of flooding? I'm afraid that when the flood recedes, the house will collapse, right? The so-called repair of the house is only afraid of building a new thatched house.

Every year, the people of the tribe will not choose a good place to build a house? Thinking that others were still primitive tribes, Mu Tong didn't ask any more, anyway, she definitely had to choose a new location as soon as possible and build a house that was not afraid of wind and rain.

By the way, I heard that the winters here are very cold, and you need to have enough cold protection function.

Hey, this has to resist wind and rain, it has to be warm in winter and cool in summer, and you have to choose a place that is not afraid of flooding, where is it suitable?

Mu Tong finished drying the quilt, entered the back room, and thought about this question seriously. If you don't want to be flooded, you have to build your house on high ground. The entire tribe of the Chishui tribe was built in this valley, and the terrain was slightly higher, only the place behind the tribe near the cliff, there was a small hillside that was not low and not small.

Mu Tong walked out of the house and walked towards the small hillside. Seeing Mu Tong walking out, Ah Yu hurriedly packed up the prey snake in his hand and walked out.

Dorjee looked at his brother and sister-in-law who came out of the courtyard, pursed his lips and snickered: The wise and martial brother has also become a wife and slave.

The elder brother and sister-in-law went out, and the diligent Dorjee took a broom again and went into the house to sweep the stagnant water in the house.

Seeing Mu Tong walking towards the back of the tribe, Ah Yu followed in a few steps: "Ah Tong, what are you doing on the small hillside?" ”

"I'll see, by the way, can it be flooded there every year?"

While the two were talking, the hill that was not far away arrived.

"You see, you can drown there." When she arrived at the small hillside, Ah Yu pointed out to her the location that could probably be flooded when there was a big flood in previous years.

Mu Tong took a closer look, that location was about ten meters high under the hillside. If the water level of the big water rises by more than ten meters, isn't the surface of the Chishui River at least twice as wide? That's a staggering number, how much water is there.

Dizzy, how can the thatched huts in the tribe withstand the soaking of this big water, it is estimated that after the big flood every year, it basically has to be rebuilt.

"Does the tribe have to rebuild the thatched hut every year?"

"Yes." Ayu didn't understand what Mu Tong was asking for, it was an indisputable fact that the thatched huts in the tribe needed to be rebuilt every year.

"Then why don't you build a grass hut on a high point, like this hillside?" Built on a small hillside, at least there is no need to worry about the annual flooding, let alone rebuilding every year.

"The hillside is full of large boulders, and there is no way to drive piles." Ayu Dao: At the beginning, there were people in the tribe who built the grass hut here, but there was no place to drive piles to build the foundation, so the grass hut could only be built on the ground.

Mu Tong's eyes were embarrassed: she forgot that this was a primitive tribe and had no ability to drive piles in the stone ground. If you can't drive piles, you can't build foundations. Doesn't a grass hut without a foundation have to be blown apart when it encounters a strong wind?

I heard that in autumn and winter, the wind is quite strong. Especially in winter, it is not only windy but also cold. Instead of rebuilding a thatched hut once a year, building a house on this hillside has to be rebuilt countless times?
