I, the final BOSS of the beta test server!

Although he traveled through time just before the game's closed beta test, Last did not rely on his foresight about the plot to embark on the path of the protagonist bathed in flowers and glory.
His time was hopelessly frozen in that small town called Deep Blue Harbor.
No matter what Rast did, when dusk came, the revived ancient god would destroy the entire city, along with all the traces he left behind, and time would go back and start all over again.
He was happy, and spent endless time to capture the opposite sex, studied the most unpopular and remote books in the library, and honed his skills to perfection...
I have also been desperate, trying to stop the coming of the evil god, but I gave up in the endless failure...
Until that day, after countless failures, when Rast dragged his mortal body to face the ancient gods again, he saw a figure that should never have appeared.
"Hey, according to history, Deep Blue Harbor should have been destroyed by the aftermath of the God's Descent."
The poster girl on the game cover, the future Silver Sword Master, was looking at him with confusion on her face.
"Also, who is this strange night world projection? Why is there no record of him in history books?"
Rust:?
I was about to speedrun it, and you just told me it was a plot kill?
Also, it turns out that I have been playing on the beta version for the past three hundred years?
……
Reflections of the past, echoes of history, and the embers of civilization converge into the [Night World].
The travelers walking through it are the night world players.
"They are committed to the darkness of the night, yet they shine like stars."
