"This light that has been stagnant for years, finally pouring out, is the true essence of the Calamity of Light!"
It's simple to say, but actually quite ordinary.
Consider Star Prison Tianyu and Terra as a metal room deep under the sea with Humans, Humans can live at the narrow deep-sea seabed under the shelter of the metal room, but once they leave the room, they will be crushed, drowned, and suffocated by water pressure, essentially certain death.
The good news is that this metal room is incredibly sturdy; even the currents outside won't damage it. The bad news is that this metal room has a gap, though covered with a layer of glass, it's almost the same in effect, but the glass position is very fragile.
This layer of glass has its pros and cons. The people inside the house can observe the sea through the glass and imagine what the outside world is like, but the bad news is that it is extremely fragile.
