Under the Ring of Heaven

Three thousand years ago, a celestial ring sealed the sky, declaring the earth dead. In the giant steel structure called "Greenhouse", human beings are divided into gods in the clouds and ants in the quagmire. You wake up in the bottom of the sea of ​​rust, with huge debts, incomplete memory, and your only property is a body that does not completely belong to you. In this world where you have to pay to even breathe, you have to not only survive, but to climb up from the sewers of hell and smash the glass ceilings of the gods. This is a story about prison break-out of the cage called "class" and out of the greenhouse called "lie". When the sky falls, will you choose to be a stepping stone or the hammer that breaks the boundaries?
