Birds and trees have become good friends, and although there are already many birds and trees here, there is another world between them, which belongs only to them.

The tree is the oldest and most sturdy tree in this place, and it is like a large umbrella that shelters the creatures under its feet.

Birds have the strongest wings, the sharpest eye, and the wisest minds here. It likes to fly far away and loves something fresh.

The bird does not seem to have a stable nest, it is always flying, and when it is tired, it only stops at the highest branch of the tree.

As it rested, the tree asked it, "Do you fly so constantly that you don't even prepare a nest for yourself?" ”

"What are you going to do? A bird that is born to fly non-stop, as long as it stops for a while when it is tired, why bother to worry about yourself? ”

But the bird does not stay in any place at random, it is always fixed, standing on the highest branch of the tree, closing its eyes slightly in the wind, and swaying its body gently.

The tree asked it, "There are already a lot of trees here, why do you just stay on me?" ”

"Because you're different."

"What's the difference?"

"You are the first tree here, and the tallest, strongest tree. And I was the first bird to discover you, and we should have a special meaning for each other. ”

The tree didn't understand, but it said, "Then ...... I'll keep this branch for you, and you'll only be allowed to rest on it. ”

The tree is always envious of the freedom of the birds, and the tree cannot go anywhere, but it is full of curiosity about the outside world. So the bird became its eyes.

"There is one more creature in the world, and it is called human."

"Oh?"

"Don't worry, they are very weak, they hide in dark caves every day, they like to huddle together, and they don't dare to act alone."

Birds don't just bring news from the outside world, they always bring a lot of strange seeds: "This is the seed of a flower, and it is said to have petals of seven colors!" ”

The bird asked the little animals on the ground to help dig a hole, threw the seeds into it, and covered it with fertile soil.

These seeds sometimes germinate and sometimes rot.

"Not all seeds can germinate here, they need different conditions," the bird said. ”

"I thought they weren't ready to join us." ”

"Huh." The bird smiled, "Maybe your thoughts are more meaningful." ”

Sometimes the bird flies away, and the tree looks far away in the direction it disappears. As far as the trees can see, there are not only weeds, but also many tall and short trees standing in the distance, and colorful flowers under the trees.

When the bird flew back, it was panting heavily.

"Remember the humans I told you?"

“…… Weak creatures? ”

"They're not weak anymore." "They learned to use tools, to cut down trees with tools, to make tools into trees, to hurt animals with tools." ”

The tree began to worry: "What should I do then?" ”

"Oh, don't worry." The bird said, "I met them from a long way away...... They used tools to attack me. ”

The tree didn't know what the "tool" really looked like, he just began to worry: "You don't want to fly too far." ”

"Why?"

"It's too dangerous outside, you should stay with us."

"Ahh The bird said, "I'm a bird, so the bird should fly everywhere." ”

"Then ...... Don't fly where there are humans. ”

"My parents told me not to fly here...... When it's just you here......"

Every time the bird flies outside, the tree starts to worry. When he felt a gentle pressure from his tallest branch, the tree breathed a sigh of relief: "You're back." ”

"Humans began to build cities and learned to use more powerful tools."

"Are they getting more dangerous?"

"No!" The bird suddenly laughed, "That's exactly what I'm going to tell you!" ”

"Humans have not only learned to use tools, but they have also learned to get along with us! They no longer cut down trees at will, they no longer hurt animals at will, they ask us for what they want. ”

"But they're still going to hurt us, aren't they?"

"It's the rules of the world."

"Rules?"

"Just like a tiger eats a rabbit and a rabbit eats grass, are both tigers and rabbits evil? This is the only way they can survive, life continues in such a cruel way, every living being is a victim, they have no choice. ”

"......" the tree was silent for a long time, "you have to eat small insects too, right......"

"We don't have to worry about humans anymore! I can fly freely in the human world! They have a skill that all creatures don't have! ”

"What?"

"Create! They can create something that has never been done before, they are an extremely intelligent creature. ”

"Smarter than you?"

"They know more than I do, and are as curious about the world as you and I am!"
