The Dragon of the Apocalypse

A giant dragon nearly ten thousand meters long stands on the ground. With its own gravity alone, it causes the surrounding space to distort, elemental tides riot, dark clouds cover thousands of miles around, thunder and lightning thunders, and the sea rolls up thousands of meters of violent waves.
Within a hundred miles around the dragon, angels, demons, and devils covered the sky.
Giants, dwarves, humans, elves, orcs, and goblins covered the earth. They raised their sharp blades and shouted to let the dragon occupying the main material plane leave.
The giant dragon just glanced at it from the corner of his eye, not even wanting to say a word to the group of ants.
His body burst into pure and flawless white light!
Endless light and heat burst out, like stars falling into the world!
When the star disappears.
Thousands of miles of red land! The sky is filled with smoke and dust that can obscure the world...
