Lu Ban took my thanks in his eyes and nodded.

"Boy, you don't have to thank me, it's just a door, and I have to bother you for the rest of the trip."

"That's natural, but wait a little bit for me."

I removed the obscuring canvas, swept out the broken bricks and dirt in the corners, and called the property to help clean the door.

"They're inferior?"

Lu Ban looked at the cleaning aunt and asked me, which caused the cleaning aunt to look displeased.

"Huh? No, no, no, everyone is equal in this society, but the occupation and division of labor are different. ”

I hurriedly explained, otherwise Aunt Cleaning would kill me with her eyes.

"You just spoke into the little box in your hand?"

Lu Ban stared at the phone in my hand.

"Oh, this? This is called a mobile phone, and he can talk to people far, far away, and even meet, of course, not really meet, but a kind of projection. ”

"Are there any restrictions?"

"Of course not, if the phone bill and signal don't count."

"Can I take a look?"

"Oh, of course, I can..."

There was a click, and my face turned green.

"I can buy another one...

Yes, the phone didn't live for three seconds in his hand before it became a pair of parts.

"It's complicated, there's a lot of stuff in here that I don't recognize."

Nonsense, if you can read it, it's not one of the greatest inventions.

"What, if you don't understand, can you pay me back?"

"Oh, it's expensive, isn't it?"

Surprisingly, although Lu Ban did not study the phone thoroughly, it was easy for him to disassemble and reassemble.

"No, I can buy you one if you like."

took Lu Ban's reinstalled mobile phone, it was as good as ever, amazing.

"Okay."

Yes? I'm just polite. Can't you just be humble?

"But I didn't know you got it. Over there? Can it still be used? ”

"Limited?"

Luban looked at me.

"Well, let's explain to you that this device can turn sound into data, and the data can be transmitted to the base station, and then diverged from the base station to achieve information transmission, and the base station is also a satellite."

I don't know if I'm right, I'm not an expert on this after all.

"Can you build your so-called base station?"

"Theoretically, yes, but that's not something I can touch."

"Where is it? Can I take a look? ”

"Upper."

I pointed to the ceiling.

"Upstairs?"

I shook my head.

Lu Ban looked puzzled.

"Outside the Earth."

"Outside the sky?"

Lu Ban looked shocked.

I nodded.

。。。。。。。

In the following time, Lu Ban dismantled almost all the household appliances in my house, including the toilet and microwave, and even when I was watching TV, he directly dismantled the TV to see if there was really anyone inside.

If he hadn't been able to put it back together, I think it would have been a lot of money.

It wasn't until there was really nothing left to tear down at home that Lu Ban asked me to take him out.

This time, I chose not to drive, and took him on the bus and subway, and the expected route was to take a sightseeing cruise on the nearby canal.

on the bus.

"Where is it heading?"

"Buses have regular routes, they stop at intervals to get people on and off, and they're cheap."

"Your money is made of paper?"

I handed him a hundred dollars and a fifty dollar one.

"Who's on it? Your king? ”

This caused the person playing with the mobile phone next to him to look at him.

"No, he is a great man in China, he saved the country and led the people."

"That's not still the king."

Yes and no, I don't know how to explain to him the difference between the president and the king, it doesn't matter anyway.

"Where does he live?"

"Where we're going."

"Whatever you want?"

In his mind, the king was not something he could see casually.

"Of course, he's been lying there for a long time."

"He's dead?"

"Yes."

"Is it going to the mausoleum?"

Lu Ban was even more puzzled.

"No, people don't build mausoleums now, and there is not enough land."

"Then he...

"Let's go, get out of the car first."

I couldn't stand it, so I quickly pulled him off the bus, and he was already surrounded by the whole bus, and the people talked about it horribly.

Get out of the car and find a place with fewer people.

"He is Grandpa Mao, before I was born, he died, he was a great man in this country, after his death, his body was placed in a crystal coffin in a column, for future generations to admire, this country encountered a near annihilation a hundred years ago."

Well, this explanation can satisfy him.

Lu Ban nodded, looked at the banknotes, and whispered.

"But this country survived, and I didn't."

I heard it, but I prefer not to hear it, I am a latecomer to history, and he is a participant, and he still did not block the iron hooves of the Qin State by building all kinds of siege equipment with his own hands.

I looked at the navigation of my phone, but Lu Ban stared at the ground.

"There's something down there? Big, fast. ”

"What?" I didn't get it.

"Below, underground."

I was stunned for a moment before I reacted.

"Oh, subway, let's go, I'll take you to see it."

A lot of times I don't feel like a chattering tour guide, but someone who constantly takes distant relatives shopping.

"Why do you want to fix the car underground?"

"There is not enough space on the ground, not only underground, but also in the water, on the ground, in the sky, and even in outer space. In peacetime, there are the most people, and there is not enough space to live. ”

Lu Ban nodded as if he didn't understand, and when he bent down to look at the subway tracks, he was stopped by the conductor.

"Why don't you let it close?"

Lu Ban, who was forcibly pulled back by me, asked me.

At this time, the subway roared, rumbling and airflowing.

"The subway runs underground without obstacles, so the speed is very fast, and if you get too close, you will be sucked by the air current, and it will be fatal for ordinary people to rub it."

Lu Ban nodded, the subway stopped, the door opened, and followed me into the subway.

We avoided the morning and evening rush hours when it wasn't necessary, and the subway was not so crowded.

"Everybody can ride?"

Luban sat next to me and asked me questions.

"Well, as long as you pay a certain amount of money, it's cheap."

"But I didn't see you paying."

I pulled out a bus card.

"Money becomes a kind of data, and the cores in this card can be used as monetary payments, but only for buses and subways."

Lu Ban took it and looked at it carefully, but fortunately he didn't open it.

"It's so convenient."

I nodded.

The main thing is to let Lu Ban feel modern life, the destination is not important, I took out my headphones to listen to the song, but Lu Ban was eyeing a foreigner.

"And the non-Middle-earthers?"

I didn't understand, and following Lu Ban's eyes, I saw a foreigner with a headset.

"They are foreigners, and they seem to be from Europe and the United States."

"They live here? Or has it already captured their country? ”

"It's just life, some of them are here for tourism, and now there are very few wars, and no one in the big countries dares to act rashly because of the existence of nuclear weapons."

I took off one of my headphones and explained to him.

"Nuclear weapons?"

"Well, a weapon that can destroy the earth, every big country has it, but it restricts each other, no one dares to move, and threatens peaceful development."
