On the ground of the Underworld, Hades's figure was rapidly flickering.
The sky seemed to tilt for a moment, stars fell to the Mortal Realm. And he was trying to move far from the impact's center point, and stabilize the Underworld Land as much as possible with his power.
That is to say, the sky of the Underworld is not the real sky, it doesn't need tools to prop it up. Otherwise, the destruction caused by Zeus's fall would not be limited to the Fields of Truth.
Whoosh—
The 'Fallen Star' swept through the air, only holding stiff for a short while before the 'Celestial Body' continued to sink.
Black flames wrapped around the 'meteor,' and the hellfire burned relentlessly on Zeus's body.
