You don't know what the next story will be, who the next protagonist will be.
In this world, there are all sentient beings in the six realms. Taking a piece of the past from it, whether it is joyful or sad, whether it is long-lived or short-lived, ups and downs in one life, can be called floating life.
Life is like a dream, but people in the world would rather perish.
(There is no fixed protagonist, it is like a united story, but there is a great connection between each other. All historical events and historical figures involved are fictitious by the author and are purely fictional)
