Everyone knows that there is a world below them, but they don't know that there is another lonely city hanging above their heads. A gilt rare coin breaks the shackles of the mortal body, awakens the extraordinary, and glimpses the twin cities. The city hanging high in the sky is not an empty city. Foreign races live here and are watching in secret. The barrier between the two cities gradually loosened, and the alien figure quietly approached. The road to awakening is thorny every step of the way. He can only continue to become stronger, protect the mortal world, fight against aliens, and explore the grievances and secrets between the two worlds that continue to this day.
