This world is both a cage and a ladder.
In AD 4770, human beings live in countless overlapping "level worlds". No one knows exactly how many layers there are, only that
-The higher you go, the richer the spiritual energy is, like the Kingdom of God; the further you go, the poorer the energy is, like a desert.
Each level is a complete world, isolated from each other, but occasionally forcibly penetrated by "level cracks". Alien beasts, treasures, or unknown civilizations from other levels may emerge from the cracks. Human beings have established a "boundary protector" organization to protect their own hierarchy for generations, resisting invasion and prying from all parties above and below. —Above the border, is it the Kingdom of God or Hell?
—Under the border, is it hometown or prison?
—And the young man standing in the center of all borders will use his own efforts to stand shoulder to shoulder with the gods as a mortal and continue to climb up.
