Immortal Reborn as a Cat

It was normal for He Muchen to travel through time and be reborn during a late-night adventure. What's abnormal is that he traveled through time with a female ghost? What's even more unusual is that this female ghost is actually my fan's fairy sister? What's even more bizarre is that the soul of the fairy sister has traveled through time and space to my cat? There is also an even more bizarre fairy sister who can actually switch bodies with Sissi in this world! (The first dozen chapters of this book are slow to read, mainly introducing the character background Goldfinger. If you don't like it, you can skip to Sissi's appearance and start reading.)
