The girl in white took Marven and his little friend to the edge of the bubble.

Fortunately, there was a reminder from the girl in white, otherwise the off-road vehicle Weiwei would definitely hit the bubble headlong.

Outside the bubbles are sea water and a variety of fish swimming around.

"It's a lot of fun. Exactly the same as an aquarium. Mia leaned on the bubbles and looked out.

Suddenly, a huge octopus rushed over and slammed one of its tentacles on the bubble. Scared Mia a lot.

"Why can't you hear a little outside?" Marven asked.

The girl in white said, "If this bubble is not soundproofed, the bubble will be noisy to death." I brought you here to tell you. The bubble is completely enclosed. It is impossible for those outside to come in, and it is impossible for those inside to go out. That's why the black-clad messenger asks where you came from. ”

Marven said: "I have already told the old man in black that we are from the earth. ”

Next, Marven told the girl in white about their experience.

The girl in white held her cheeks and thought for a long time, and finally said, "Or, I'll take you to meet someone." ”

The girl in white sits in the front row of the SUV and directs the way.

Marven asked, "Did this bubble exist before?" How did you get into this bubble? ”

The girl in white shook her head and said, "This bubble didn't exist before. At that time, the star was not completely covered by the sea. ”

Once upon a time, there were lands, oceans, mountains, and rivers on this star. Some people live in the city, and some live in the countryside. Everything is very much like the Earth.

Later the iceberg melted. The snow turned into a flood that washed away the city and the countryside. The water level also got higher and higher, and finally the highest mountain on land was submerged. Since then, only the ocean has been left of this star.

Humans started living on ships. But because of the bad weather at sea, living on a ship is especially dangerous. That's why we built this bubble that can be suspended under the seawater. The city was built in a bubble.

At that time, bubbles had an exit, but then many disasters happened. When the bubble bursts, the whole city is destroyed. Because bubbles are spherical in shape, they can easily burst if they have cracks. In order to avoid the recurrence of this catastrophe, the bubble was built seamless.

So, since then no one can come in, and no one can go out.

"So you've been living in the same city? I can't travel anywhere else. How boring is that. Marven asked.

The girl in white said, "We can go to another city on the back of the bubble." ”

"But......" Marven wanted to say that the two cities were actually about the same, and it was not interesting to travel. However, it is useless to say this, "but the strange thing is that two cities are completely upside down, and when one city is on top, why doesn't the other city fall?" ”

"I don't know. All I know is that in the old days when our stars were not flooded. There are people who live above the stars, there are people who live below the stars, and no one has fallen. It's weird. ”

Marven thought to himself: That's not strange at all. That's what the earth is. Thinking of this, Marven guessed that it might be the effect of gravity. Dad used to talk about this with a magnet before. Even Mia understands this.

But there is no magnet in the off-road vehicle, and Marven has no way to tell this truth to the girl in white.
