A Short-Lived Ghost Who Traveled to the World of Fairies and Demons!

Are you the Taoist sage Lao Tzu? Your unreliable Poding Immortal Emperor's treasure? I worked so hard to become an immortal, but ended up traveling through time into a short-lived ghost? It's not that easy to kill me... Demon God? Immortal Emperor? Game? It's none of my business. When I get here, I want to reach the top. Even if I'm a short-lived ghost, I have to be an awesome short-lived ghost. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
