From the Start, I Was a Nascent Soul, Playing the Old Monster in the Cultivation World

Yu Mu, a zoo director, woke up one day and, through a twist of fate, found himself in a world of immortal cultivation.

He figured that since he was there, he might as well make the best of it and focus on staying alive.

What? He was at the Nascent Soul stage from the start?

This is just my luck!
