Back in Time: Apocalyptic Awakening

I, Lin Yi, an ordinary librarian, suddenly became the DJ of time, controlling the beat on the dance floor of the apocalypse. I originally thought that saving a little sister would be an extreme challenge, but then a big man in black robes appeared and told me: "Boy, you are just a newbie!" Just when I was almost cornered by his time suppression, hey, Amy and I held hands, and our powers actually merged! With a reversal, we escaped. This post-apocalyptic world is just a battle royale game. Let's see how I can use the time buff to pass through the levels and become the true king of survival! Want to see how I come back? Then don't blink and jump into this crazy time vortex with me! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
