Staring blankly at the enclosing walls for a while, Number One couldn't help but say, "This place is really beautiful, what is this place?"

"What's a botanic garden?"
"A place for placing plants and for people to enjoy looking at them. Bipedal Beasts, that is, humans of the past, were very fond of such facilities. They liked to come here during their leisure time to pass the time by observing plants."

"Most are only for ornamental purposes and are poisonous, and moreover, they require a lot of sunlight, clean water, and fertile soil, etc."
"What a waste!" Number Two cried out, "Using precious land and resources to cultivate things you can't eat, were humans this wasteful?"
"To the humans of the past, this was merely a common way to entertain themselves."
