[No System + multiple worlds + not invincible + no harem]
On an ancient wasteland sealed away by the passage of time, the wind howled.
Far into the distance, all that met the eye was an endless expanse of sky and earth. Only at the far-off horizon was there a tiny black speck.
As time passed, the speck slowly moved, and its shape gradually became clearer.
Beneath a ruined stone fortress in the wasteland stood a fallen self-destroyer, his face haggard and his eyes dim.
When he recognized the newcomer, an expression of disbelief flashed across his face, as if he were seeing a ghost that should not exist. But it vanished in an instant, replaced by an indescribable sorrow that surged through his eyes like a tide.
"You... why would you take the same path as us?" The self-destroyer's voice was hoarse and trembling, as though uttering that simple question had drained all his strength.
The newcomer remained silent. The wind howled between them, stirring their robes and making them snap in the air, as if telling of a tale unknown to all. The sound was like a sigh, yet also like a warning.
"To return all of this to the cosmos."
A voice, no one knew whose, carried a trace of resolve, as if making one final stand against fate.
It echoed across the wasteland, only to be swiftly swallowed by the endless darkness.
