Where are they at the beginning of the novel "Burning the Milky Way at Night"? What are you doing?

Where else? They are in heaven. According to the setting of the novel, there is a huge "sea" in the sky (you can understand it as the city of the sky). After the whale dies, it will fall down and be eaten by other fish or big birds. Because this big whale is big and light, it takes a long time to fall, which is enough time for small animals to settle on it. As for what is dug on it, I guess it is the special fat particles on whales (ouch ~), which are dug back as fuel. (; ? д`)ゞ
