The story takes place in the Great Migration Era of 2380. Humanity has completed its migrations to Mars, Europa, Callisto, Ganymede, and Saturn's moon Enceladus.
At eighteen, a boy from Earth named Xingchen dreams of soaring freely through the universe, but the gravity of reality keeps him firmly bound.
Having barely escaped Earth's cage, he must now face all kinds of mutants, enhanced humans, evolved humans, artificial humans, and intelligent machines.
In an age when the rich have technology and the poor can only rely on mutation, freedom comes at a price.
