Young Lin Xun accidentally ate a kind of "cloud ear mushroom" while camping in the mountains, and found that he could enter another world in his dream - "The Realm of Cloud Whales", a continent floating in the sky, where whales swim among the sea of clouds, islands can sing, and rainwater is a conscious life form.
He can travel freely between the two worlds, but every time he returns to reality, there will be strange deviations in time, weather, and even the shape of the city. As he explored more, he found that the real world seemed to begin to "float", as if the continent in the clouds was approaching the human world...
