No one expected that the rain would last for two days and one night. Early in the morning of the third day, the sky gradually began to clear.

After the rain, the sky was pale white like a fish's belly, exceptionally clear, and the endless sky was exposed blue, and a touch of white clouds dotted the blue. Gradually, the white clouds drifted by, and a round of rainbows appeared in the sky.

"Wow, Panpan, Rainbow!" This is the first time Lan Ruyu has seen a rainbow when she came to the interstellar world.

"Seeing a rainbow means good luck! How lucky! ”

"A rainbow is an optical phenomenon in meteorology. When sunlight hits water droplets in the sky, the light rays are refracted and reflected to form an arched multicolored spectrum, which is very common. ”

“……”

Lan Qiyu was silent, "You can not speak..."

"Alright, let's go out and see how the devastation is going outside."

Although Lan Qiyu was mentally prepared, when she went out, she saw the yard covered by a layer of yellow sand, and the corners of her mouth couldn't help twitching.

Her yard has a fence like this, so isn't there yellow sand everywhere outside?!

Sure enough, as soon as he walked out of the courtyard door, Lan Ruyu stepped on layers of yellow sand, and there were two shoe prints after two steps. Look at the surrounding vegetation again, and the leaves are thin layers of sand.

On the road, there are already quite a few people and robots sweeping the streets.

"Your Lord, are you here?" An uncle put down the machine in his hand and smiled at Lan Ruyu.

"Good morning, Uncle Charles, what is this?" Lan Qiyu pointed to the machine at Charles' feet.

"Huh? It's a sand sucker. More than 30 years ago, the ancient earth suffered a sandstorm, and the oasis was covered with yellow sand. At that time, Lord Lanqike bought us these sand suction devices to facilitate cleaning. ”

Lan Qike, Lan Qiyu's father.

"Well, okay, thank you, Uncle Charles."

Lan Qiyu inspected the way, and along the way, everyone was cleaning with the robot with a sand suction machine. Because of the strong wind, many flowers and plants were uprooted, and even some branches of the big trees were blown off and hung down by the roadside.

Fortunately, Lanks has already distributed the hundreds of thousands of robots all over the oasis to start cleaning up, otherwise there may be no roads.

Walking to a slightly dilapidated house, an elderly man climbed a ladder to repair the roof that had been blown by the wind.

Despite the help of the two robots with the smart ladder, Lan Ruyu was still afraid that the old man would accidentally fall down or flash his waist, "Grandpa, will you come down first?" ”

When Griffin heard the voice, he slowly turned his head to look at the source of the voice, and saw that it was Lan Yiyu, and his face smiled with folds, "Lord Lord, are you here?" With that, he pressed the button and the ladder went down automatically.

"Grandpa, was your house blown by a strong wind?"

"Yes, the old house is hundreds of years old, but it can still be lived in by tinkering, anyway, I'm the only one at home, I'm leaving, I'll just take a break." Griffin sighed and looked at Lan Yiyu kindly.

After chatting with Griffin for a while, Lan Yiyu learned that when Griffin and his wife were young, they worked hard to farm for their son to go to other planets to study, and the son went out and never came back, and Griffin's wife also died a few years ago, leaving Griffin alone to live in a huge empty house.

"Don't blame him, don't blame him, it's not easy for him, it's already bitter, let's finally get him out, let him live a good life outside, as long as he lives well. We're all dying, whatever we do, it's a drag. ”

……

"Alas, there are still quite a lot of left-behind old people on the ancient earth..."Lan Ruyu looked at the information, there were more than 1,000 people who left the planet in the past two hundred years, and the number of people who came back was less than 20.

As a result, those who originally had offspring gradually became empty nesters over time.

This matter is not easy to deal with, first, I don't know where those people have gone, and I can't find anyone at all; Second, even if she finds it, she can't force people to come back, right?

"Let's think about the problem of the house first, I think the house still needs to be strengthened and renovated."

The current houses on the ancient earth are basically hundreds of years old, and they have experienced several storms and sandstorms, and some houses have long become precarious.

Lan Qiyu directly saw that some abandoned houses that had been uninhabited all year round were directly blown up by the wind, the yard was overgrown with weeds, and the rust on the iron fence had already peeled off.

"No, no, no, why are these houses so expensive?!" Lan Ruyu originally wanted to buy a residential house directly on the Star Network, but after a casual search, it was hundreds of millions of houses.

The total population of the ancient earth is more than 30,000, and there are nearly 20,000 households in total. If she bought one set per household, wouldn't it be trillions again, and she couldn't afford to pay for the windproof protective cover.

Lan Ruyu felt that the money she had just earned was about to bottom out.

"You can buy materials to build robots to reinforce, anyway, you will need to build robots for the expansion of the oasis later."

Nowadays, almost all the houses are built by robots, and it is rare to see artificially built houses, one is because it is time-consuming and labor-intensive, and the other is that the artificially built houses are not strong and cannot be lived in old, just like the ancient earth.

There were only three construction robots on the ancient earth, all of which were thousands of years ago, and now I don't know where they were piled up with ash.

"It should be expensive to build a robot, right?!" This kind of function sounds like a lot, and in Lan Yiyu's cognition, the more functions, the more expensive it is.

Shen Panchi: ......

"The average one is about five million, and it takes about ten construction robots to reinforce a house the size of yours."

"That's 50 million for a house, and 20,000 is 1 trillion? It's a little cheaper than buying a ready-made house. And it can be used later. ”

With the comparison of the previous trillions, and then looking at the trillions of this and the fact that the service life of the building robots is more than a few hundred years, Lan Qiyu feels that it is much more cost-effective.

"Don't panic, wait for me to see which one has a higher price for building robots." As a good buyer, shopping around is one of the rules that Lan Niyu follows when buying things.

"You can find Wen Chi, the Wen family was in the real estate business back then, although the focus of the Wen family has shifted from business to politics, but a large part of the family business is still about real estate."

The Wen family is the largest real estate tycoon in the Federation, specializing in ultra-high-end residential areas and some important buildings. For example, the floating island where Shanshan lives and the building of the Federal Research Institute were all built by companies under the name of the Wen family.

"Smell late? It's not good..."

When it comes to Wen Chi, Lan Ruyu is a little weak-hearted, she and Wen Chi are not like her and Wen Qilian have a large part of the interests involved, she and Wen Chi are simple friends.

Coupled with the fact that she has always disliked frequent contact with friends to maintain relationships, the two have never spoken since the last time she said to Wen Chi that she would not send breakfast.

"There's nothing to be embarrassed about, and you're not spending money. Besides, are you still embarrassed? Shen Panchi said lightly.
