The girl in white treats Marven and his friends as VIPs, so she books the most luxurious hotel in this bubble city for Marven and them.

In this hotel, you can not only look down on the city, but also simulate the effect of living at sea level. The most popular movie "The Sea" is playing on the TV in the hotel, and the room shakes with the camera of the movie. The bed is a waterbed, and lying on it will also shake with the surface of the sea.

After a tiring day, Marvin and Mia both slept soundly in this luxury hotel. When I was ready to go out the next day, I vomited all my breakfast.

"Are you sick?" The girl in white asked.

"It's not." Marven shook his head and said, "It's just that my head is dizzy." After shaking all night, I couldn't stand it. We have to go. Thank you for being with us. ”

The girl in white shook her head: "You're welcome." Thank you also for telling our mayor how to make batteries. ”

"That bearded uncle is the mayor?"

"yes. Every city elects a person who has contributed the most to the city as its mayor. We, the mayor, invented wireless communication technology. Now the eight thousand bubbles on the entire Bubble Star are connected. He's also helping a lot of poor bubbles solve their food and energy problems. It is said that some bubbles have proposed to make our mayor a star commander. Manage whole stars. ”

"Wow, I don't see it. Then here we go. Marven took Mia to the hotel parking garage and got into the car, waved at the girl in white, and then carried his grandfather's old cane.

No response.

Marven twisted it again.

Still no response.

"Grandpa Cane, why don't you drive?" Marven shook his cane.

Grandpa Cane yawned and said, "Marven, don't shake it." Have you forgotten that the night on this bubble is not really the night. ”

Oops, oops. Forget about it.

Because the bubbles don't shine sunlight in the sea, the day and night on the bubbles are simulated by the lights overhead.

But the bubbles can only stay below the surface of the sea, and they can't see the sun at all. What can I do?

At this time, the hairpin of the girl in white made a "beep" sound.

The girl in white said a few words to the hairpin and said to Marven, "The mayor is waiting for us in the hotel lobby." ”

In the lobby of the hotel, Marven meets the bearded uncle.

When the bearded uncle saw Marven, he happily put a big iron box in his hand and said, "Marven, Mia, thank you." This is a gift for you. ”

The big iron box was too heavy, and Marven didn't catch it. It fell down and smashed a hole in the marble floor of the hotel. Almost smashed Marven's foot.

Uncle Bearded called the hotel staff to discuss the loss of money.

The hotel staff waved their hands and said, "We can't let you lose money." If you like, you can smash the whole hotel. ”

"Huh?" "Huh?" Marven and Mia looked at each other and thought: Is this okay?

"Let's go and have a look in my lab. I made the battery. ”

"Yes." Marven found it incredible.

Although it is not difficult to make batteries, it is also quite troublesome to find various materials.

Everyone came to the factory area where they went yesterday, and Uncle Bearded took Marven to a workshop. In this workshop stands a huge iron house. It looks like the big iron box on Iron Man.

"That's it." Uncle Bearded said.

"Who's that?" Marven asked.

"Batteries."

"So big?"
