When he was a child, Yu Qichao saw photos of the human world before the cataclysm in a book.
Different from the coldness of the underground ark, the world in the photo looks particularly bright.
So, his longing took root and sprouted, and when he had the ability, he stepped out of the door.
The moment he reached the soil, looking at the devastated wasteland world, Yu Qichao thought:
"This is my world."
"What do you do?"
"I'm just a scavenger."
"What's that?"
"Searching for freedom."
Intention: live well
