A long, long time ago, the old man was still a child, a little friend with teeth.

At that time, not only did he have teeth, but all the children had teeth. Not only do all the children have teeth, but all the adults have teeth too.

One day, an alien came up to this star. He was a magician.

The magician told the king that he could grant one of the king's wishes. Any wish is fine, but only one wish can be fulfilled.

The king did nothing and meditated every day. Every time he thought of a wish, the king shook his head, thinking that there must be a better wish. And so it went on for a few days.

One day, the prince, the king's son, came to the king, hoping that his father would make the magician grant his wish.

Because the prince loves to eat cream cakes, he wants to turn the star they live in into a cake that can never be eaten.

The king did not come up with a better wish anyway, so he told the magician of the prince's wish.

Sure enough, the magician turned the star into a cake covered in cream.

From then on, the prince had endless cakes. The prince was happy.

All the people on this star don't have to worry about food anymore. The king was also very happy.

Almost all the people on the stars no longer eat anything else, only cake.

Slowly, all their teeth fell out.

However, they are not worried about losing their teeth. Because you don't need your teeth at all to eat cream and cake.

Every time they lose a tooth, they have to hold a celebration meeting to celebrate that they have become the most loyal citizens of the cake star.

After the death of the king, the prince became king.

Of course, the new king has no teeth, who made him love cream cake so much.

He personally served as the president of the Academy of Sciences and led many scientists and engineers to make many great inventions - cars made of cream cakes, mobile phones made of cream cakes, soccer balls made of cream cakes, clothes made of cream cakes......

And, of course, the refrigerator and washing machine made of cream cakes that Marvin and Mia had seen at their grandmother's house.

The lifestyle of the people on this star has changed dramatically, and the way people have fun has changed dramatically.

For example:

In soccer, for every goal scored, the team that scored the goal can eat the goal they kicked. The team that conceded the ball could only watch others eat. The more goals you score, the more you eat. If you can't score all the time, then the team will have to go hungry.

If you can't eat enough, how can you win?

The winner of the soccer match is entitled to eat the giant golden soccer statue on the side of the soccer field. It's a lot more interesting than the winner on the planet who can only take a bite of the gold medal.

"Wow, that's a nice reward!" Marven was very envious.

"Yes." The old man said while munching on corn, "At first, everyone thought that this kind of life was very good. But slowly, the problem came. If you eat too much cake, you will not only be prone to tooth decay, but also lose your teeth in the end. And you can't eat anything else without teeth. Many people want to improve their food, but they can't do it. ”

"Isn't it possible to grow all kinds of food?" Marven asked.

"Look outside." The old man pointed out the window, "This star is covered with thick cream, and many things can't be raised." That's why I chose to live on this mountain. Just roll that cream down the hill like a snowball, and the ground will be exposed. ”

"But why do you still have teeth?" The little boy asked. That's the key question.

"yes, I was about to talk about me." The old man smiled, then got up and squeezed two more glasses of juice for the little boy and his father, and continued—
