On the vast grassland, a light blue car is driving wildly on the road.

This kind of car is called Razer. It has all the functions you can think of. One day, I drove Lasser to Hengyang, but I didn't know the way. You must ask, "What should I do?" Don't worry, just press the time travel button and the destination will arrive soon. You may ask, "What if I can walk and get caught in a traffic jam?" Don't worry, press the fly button and the car will fly immediately and easily cross the queue.

Once, I drove Razer to the seaside and pressed the diving button. Razer immediately turned into a submarine and entered the sea. I drove around the sea and found the ancient city of Atlantis, ancient shipwrecks, unknown creatures ... and visited many places. You will definitely ask, "Aren't you afraid of being stolen for such a good car?" No, because Razer has an anti-theft system and the car lock is voice-activated. Only the voice of the owner can open it, and recording is not allowed. The car thief can't open it. If the car thief forcibly opens the car door, he will be hypnotized by Razer's hypnotic needle, and then Razer will call the police immediately. How's it going? Razer is not amazing enough? If you have time, come and see its location!

Great! My parents finally promised to take me on a trip to Mars on Flight 19! I bounced back and forth in the house.

When we were ready, we set off early in the morning. When I arrived at the rocket launching site, I set off with curiosity and excitement. With a loud noise, we arrived at Mars.

Wow! The surface here is so strange! They are all deep red. In the dark blue universe, Mars is like the sun, one is a big fireball and the other is a small fireball. I sighed: "It's amazing here!" As a result, as soon as I finished speaking, two uninvited guests appeared-Martian soil messengers. They arrested us without saying anything and put us in the bad guy detector. After some twists and turns, we were released

They took us to their kingdom to play, where we tasted local food and visited many famous buildings, one of which shocked me the most. 2008 is a free-floating and mobile ANA building. The Ana building was artificially built by stars outside the milky way galaxy. But they didn't cherish it, so they were taken back and reformed by Martians.

After playing, we went back. Although we are gone, our good times together will not disappear. I believe that no matter between people or between people and aliens, there will be good memories, because trust often creates a beautiful realm.

There are many beautiful things in the future city.

There is a super car, which floats in the air, so that there will be no accidents. It's even weirder in the car. If you sit in a chair, it will automatically massage you. If you press the button on the car, the car will run automatically. If the bad guys attack the car, the car will move to a safe place in an instant.

Houses in the future cities will be more interesting. If you want to buy something, there is a food conveyor belt at home. Just put money on the machine and say what you want, and money will become what you want. When you make a phone call, the phone will display the image of the person you are talking to. The walls at home can adjust the most suitable temperature with the change of weather, which is similar to air conditioning. It becomes cool in summer and warm in winter. There is also a TV set embedded in the wall. You can play programs you haven't seen without the remote control. Just say what you want to watch and talk to the characters on TV.

There are many advanced things in the future cities, and these things are waiting for us to invent and create. I believe that humans can make these things one day. I believe that nothing is impossible as long as they work hard.

The current car anti-theft equipment is not good at all. Future cars should be equipped with a set of anti-theft equipment. If the thief is interested in this car, the car will spray a little glue, and the thief will be caught immediately.

Now, when the road is blocked, we have to wait for several hours. In the future, cars can automatically adjust vehicles and directions and clean roads. In the future, cars can fly to the sky, dive under the sea and drive on land.

The most important thing is not to have an accident. You see, this damn car accident has torn many families apart. People's lives are not guaranteed.

Also, a group of thugs who intentionally hurt cars can be photographed by the surveillance inside, and everything can be seen from a global perspective.

How I want a car like this! I believe that with the development of science and technology, cars and everything in the future will get better and better.
