I, the Final Boss of the Beta Server!

Rast’s time was hopelessly frozen on the same day after transmigrating into the western fantasy game Snow Moon Emblem. No matter what he did, when dusk arrived, the resurrected Old God would erase the entire city known as Deep Blue Port, along with every trace Rast had left behind. Time would rewind, and everything would begin again. He had once been joyful, using endless time to pursue various women, studying the most obscure and remote books in the library, honing each of his skills to perfection… He had also despaired, attempting to prevent the descent of the evil god, only to fall into utter hopelessness amidst endless failures… Until that day, after three hundred years of rewinding and failing, when Rast once again, in his mortal body, faced the Old God head-on, he saw a figure that absolutely should not have appeared. “Eh? According to history, Deep Blue Port should have been destroyed by the aftermath of the divine descent.” The poster girl from the game cover, the 「Azure Silver Sword Saint」 Shiltina, was staring at him with a face full of confusion. “And also, who is this strange Historical Echo instance NPC, and why is there absolutely no record of him in the chronicles?” Rast: ? So this is a replica projected from past history, and I’m just an NPC in the historical instance? So, I’ve been playing the beta server for a whole three hundred years? …… Breaking free from the shackles of time, the prisoner shattered the cage of history. And thus—— A player more terrifying than any boss was born.
