Reincarnated as an Extra: I had an Ascension Tower

The doctor's frantic shouts faded into a muffled blur. Then, nothing. I thought I was dead.



But… pain? I felt pain! My eyes jolted open, taking in the unfamiliar yet strangely familiar room. "Weird, where am I?"



An interface blinked to life before me:



[You are blessed by destiny.]



[You have gained access to the system.]



[Loading 1%... 2%... 3%... 100%]



[Accessing memories of previous owner]



Memories flooded my mind—someone else's life, someone else's secrets, leaving me reeling with confusion and a strange sense of displacement. Wait, this person is... an Extra?!



[System activated]



[Objective: Conquer the Ascension Tower].



What did "blessed by destiny" even mean, and what was the Ascension Tower?
