It was indeed fine for now. But if it rained for a while longer, even the deep-drilled and widened ditches wouldn't be able to release the floodwaters in time, and the flood would surely reach the tribe.

Lu looked at the rain outside and felt relieved. "I've lived so long and never seen such a heavy rainstorm. If we were still living in the valley tribe, we would definitely be doomed."

It was as if the sky had leaked, and all the water in the sky was pouring down to the ground. Lu felt that the word "downpour" that Qiao Yu had once used couldn't describe it.

The most important thing is that the rain was not only heavy but also long. Counting from the time it first started, it had been raining for half a month. There was a day when the rain stopped, and everyone thought it had stopped and started cheering, but when they woke up the next day, it started raining again.

The rising water in the river had no time to recede, and the rain poured down again.

If Qiao Yu had not ordered people to deepen and widen the ditches on both sides in the spring, the ditch would have been high at the top and low at the bottom, with the lowest end directly connected to the river. The Dragon Tribe would have been flooded long ago.

"Although there is no problem for the time being, we still need to make preparations." Qiao Yu said.

She looked at Ming and said, "Ming, calculate how many houses can be created on the lower two floors of the first residential area if the upper floors are squeezed together. The fifth and sixth residential areas are slightly lower, so I want to relocate the people on the lower floors there and put them here for temporary accommodation."

"Okay, let's do a count," Ming said.

Now that the tribe has grown, he is no longer alone. After the God Tribe moved here, Qiao Yu selected four of the more outstanding people in the literacy class to help him.

During this time, they completed household registration for the people of the God Tribe and the Sun Tribe, recording in detail where each household lived, how many people were in the family, each person's age, and which team they worked for.

To this end, Qiao Yu brought out the bamboo slips and brushes. As for the ink, she was troubled because she had no idea how it was made. So she passed the question to Ming, leaving him and Wu Yue to worry about it.

As expected, professional matters should be left to professionals. Not long after, Wu Yu made the ink.

Although the scent of this ink was different from the ink Qiao Yu had smelled in his previous life, it had a bit of a stinky smell, and the words written with it had no luster, but at least it was usable. It was much better than writing with charcoal, which would become blurry and dim after being rolled up twice, making the words difficult to see.

After the five of them completed the household registration, they selected neighborhood committee members and residential area sanitation workers in the newly built residential area to manage the residents' safety, hygiene and other issues.

Now we need to temporarily move residents living in low-lying areas to houses on higher ground, and this matter needs to be handled clearly.

In fact, except for the first residential area, Qiao Yu chose high ground for the second to sixth residential areas. On the one hand, this was to avoid humidity and summer flooding, and on the other hand, it was to facilitate the operation of the water diversion system.

In order to avoid flooding and provide a drainage area for the water diversion system, Qiao Yu dug large ponds in the low-lying areas under each residential area and put many fish in them.

The water in the pond is alive. The water from the top of the residential mountain flows down and into the pond. The pond has an outlet. After the large and small stones are piled up there to block the fish, the water will continue to flow down, into the ditch, and then into the river below the tribe.

So even if there is a flood that reaches the tribe, their residential area will be safe for a while.

However, Qiao Yu likes to do things in advance to avoid being in a hurry when the situation really comes.

She then said to the telegram, "Tell the guards to keep an eye on the flood situation outside the city. If anything is amiss, report it immediately."

"Yes." Dian said.

He and Qiang are now responsible for the security of the tribe.

Seeing Qiao Yu arrange everything in an orderly manner with a confident look, the people who were panicking at the heavy rain gradually calmed down.

Yes, their tribe is safe.

At first, when Qiao Yu asked everyone to dig ditches and ponds, no one took it seriously. However, due to Qiao Yu's extraordinary intelligence, no one expressed these emotions, thinking that it would only take some manpower and time, so they just dug.

Unexpectedly, these ditches and ponds are now playing a huge role.

The torrential rain, undeterred by everyone's anxiety, continued to fall. The river swelled, and the village's drainage ditches were overwhelmed, causing flooding in some low-lying areas. In the fifth and sixth residential areas, the water was threatening to flood the lowest row of courtyards.

Qiao Yu asked, "Have you completed the statistics I asked you to do?"

"It's ready. The bottom two floors of the first residential area can be used for occupancy," Ming said. "Once the people from the bottom floors of the fifth and sixth residential areas move in, they can squeeze in and be fully accommodated."

Lu came in wearing a straw raincoat and said, "I just checked, the water hasn't flooded into their yard yet. And even if it did, it wouldn't be able to get into the house, so they shouldn't need to move yet."

When building the house, Qiao Yu insisted on laying a foundation. The house had to be three steps higher than the yard, and the stone foundation was used underneath. Although it was time-consuming and laborious, it now gives everyone a great sense of security.

After all, these houses are made of mud bricks. If there is no stone foundation underneath, the house will collapse after a few days of flooding.

It is not easy for the water to rise to the height of three steps, and the drainage system in the tribe is still playing its powerful role.

Qiao Yu looked up at the dark sky and sighed, "Even if it's not flooded now, it will be in a couple of days. The sooner we move, the better. It will also give peace of mind to the people living down there."

Everyone looked at the sky outside and fell silent.

…

At this time, people living in other residential areas looked at the sky where water was pouring down and felt very grateful.

"Thanks to God, we are not destined to die. If we were still in the Sun Tribe, we would definitely be doomed."

"That's right. In the tree house we live in, whenever it rains hard up there, it rains lightly inside. We almost died even when the rain wasn't this heavy in previous years, let alone when it rained this hard and for so long. If we hadn't moved here, we wouldn't know what would have happened to us."

As they were talking, they suddenly heard sobbing sounds coming from behind them.

Everyone turned around and saw a woman covering her face and sobbing, while her husband and little daughter were also wiping their tears beside her.

Everyone knew about her family's affairs. They looked at each other, sighed, and stopped talking.

They were the lowest class in the Sun Tribe. Caves and high-lying areas were where the higher-ranking people lived, so they could only build their tree houses in the lower areas.

Last year's rain wasn't that heavy, but the area they lived in was prone to waterlogging. The treehouse was simply a structure made of a few trees, covered with woven thatch. When it rained heavily, it drizzled inside. Even hiding inside, they got soaked, not to mention having to sleep on the ground at night.
