Chapter 133

No one thought that the rain lasted two days and one night. Early in the morning on the third day, it gradually cleared up.

After the rain, the sky was as white as a fish belly, especially clear. The endless sky showed blue, and a touch of white clouds dotted the blue. Gradually, white clouds floated and a rainbow floated in the sky.

"Wow, pan pan, rainbow!" this is the first time LAN Siyu has seen a rainbow in the interstellar space.

"Seeing the rainbow means good luck! How lucky!"

"Rainbow is an optical phenomenon in meteorology. When sunlight shines on water droplets in the air, the light is refracted and reflected to form an arched colorful spectrum, which is very common."

“……”

LAN seemed to be silent. "You can't talk..."

"Well, well, go out and see what's going on outside."

Although LAN Xiangyu made preparations in his heart, he couldn't help pumping out when he went out and saw the yard covered with a layer of yellow sand.

Her yard has walls like this. There must be yellow sand everywhere outside?!

Sure enough, as soon as he walked out of the yard door, LAN Siyu stepped on a layer of yellow sand and took two steps to get two shoe prints. Look at the surrounding vegetation. There is thin sand on the leaves.

On the road, many people and robots have cleaned the streets there.

"Lord, are you coming?" an old man put down his machine and smiled at LAN Yueyu.

"Good morning, uncle Charles. What's this?" Lan Xiyu pointed to the machine at Charles's feet.

"This? It's a sand suction machine. It's an old thing. More than 30 years ago, the ancient earth encountered a dust storm, and all oases were covered with yellow sand. Lord lanqike bought these sand suction machines for us to clean."

LAN Qike, LAN Xiyu's father.

"Well, OK, thank uncle Charles."

LAN Xiangyu inspected all the way. Along the way, everyone took a sand suction machine and cleaned it with the robot. Because of the strong wind, many flowers and plants were uprooted, and even some branches of the big tree were blown off and hung on the roadside.

Fortunately, lankes has distributed more than 100000 robots around the oasis and started cleaning up, otherwise there may be no road.

Walking to a slightly dilapidated house, an old man climbed a ladder to repair the roof broken by the wind.

Despite the help of two robots on the intelligent ladder, LAN Siyu was still afraid that the old man accidentally fell down or flashed his waist, "Grandpa, come down first?"

When Griffin heard the sound, he slowly turned his head and looked at the source of the sound. When he saw that it was LAN Xiyu, he smiled and wrinkled his face. "Lord, are you coming?" then he pressed the button and the ladder fell automatically.

"Grandpa, your house was broken by the strong wind?"

"Yes, the old house has been for hundreds of years, but I can still live in it. Anyway, I'm the only one at home. I'll go soon and make do with it." Griffin sighed and looked at LAN Yueyu kindly.

After chatting with Griffin for a while, LAN Xiangyu learned that when Griffin and his wife were young, they worked hard to farm the land for their son to study on other planets. His son never came back after he went out. Griffin's wife died a few years ago, leaving Griffin alone in such an empty house.

"Don't blame him, don't blame him, he's not easy. It's hard to get him out. Let him live a good life outside as long as he has a good life. We're all dying. Whatever we do, it's a drag."

……

"Alas, there are still a lot of old people left behind on the ancient earth..." Lan Siyu read the data. In the past 200 years, there were more than 1000 people who left the planet, and less than 20 people came back.

In this way, those who had offspring gradually became empty nesters with the passage of time.

It's not easy to deal with this matter. 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 others to come back, can she?

"Let's think about the house first. I think the house should be strengthened and renovated."

The houses on the ancient earth now have a history of hundreds of years. After several storms and sandstorms, some houses have long become precarious.

LAN Xiangyu directly saw some abandoned houses that had not been inhabited for many years, and the roof was lifted by the wind. There were weeds in the yard, and the rust on the iron fence had already peeled off.

"No, no, why are these houses so expensive?" Lan Xiangyu originally wanted to buy residential houses directly on the Star Internet, but he searched it casually, which was hundreds of millions of houses.

The total population of the ancient earth was more than 30000, with a total of nearly 20000 households. If she bought one set per household, wouldn't it be trillions? She couldn't afford to buy a wind shield.

LAN Xiangyu felt that the money he had just earned was about to bottom out.

"You can buy materials and build robots for reinforcement. Anyway, robots need to be built for oasis expansion."

Now almost all houses are built by robots, and there are few artificial houses. First, they are time-consuming and labor-consuming. Second, the artificially built houses are not firm and can't live much old, just like the ancient earth.

There were only three construction robots on the ancient earth, all of which were made thousands of years ago. Now I don't know where to pile them to make ash.

"Building robots should be very expensive?!" this kind of function sounds a lot. In LAN Xiyu's cognition, the more functions, the more expensive it is.

Shen panchi:

"The average one is about five hundred thousand. It takes about ten construction robots to strengthen a building as big as your house."

"That's a house of 50 million, and 20000 is a trillion? It's a little cheaper than buying a ready-made house. And it can be used in the future."

With the comparison of trillions in front of him, looking at the one trillion yuan here, and the service life of the construction robot is more than hundreds of years, LAN Siyu thinks it's much more cost-effective.

"Don't panic. I'll see which one has a higher price comparison for building robots." as an excellent buyer, shopping around is one of the rules LAN Siyu follows when buying things.

"You can find Wen Chi. Wen Jia was in the real estate business in those days. Although the focus of Wen Jia has shifted from business to politics, a large part of the family industry is still about real estate."

Wen Jia is the largest real estate tycoon in the Federation, majoring in super high-grade residential areas and some important buildings. For example, the air suspension island inhabited by Shanshan and the building of the federal scientific research institute were built by companies under Wen's name.

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

When it comes to Wen Chi, LAN Xiangyu is a little guilty. Unlike Wen Chi, she and Wen Chi have a large part of interests involved with Wen Qilian. She and Wen Chi are simple friends.

In addition, she always doesn't like to keep in touch with her friends to maintain their relationship, which leads to that they haven't spoken since Wen Chi said no breakfast last time.

"There's nothing to be embarrassed about. You don't spend money. Besides, you still have time to be embarrassed?" Shen panchi said faintly.
