People Are in the Underworld, Working as Caregivers

My name is Meng Po. As a materialist, I am very panicked now. Why do I really go to the underworld after death, and the underworld is still a sanatorium! What do you mean my boss is King Qin Guang? What does it mean that my customers are historical celebrities from various periods? How did they get together? I'm Chovy, you were a good choice when you reincarnated me, but why were you recruited as a caregiver and why do you want me to collect their lives? If a person is both a caregiver and a reporter, capitalists cannot exploit people like this! (This book is purely fictional, and the historical part contains a large number of artistic creations. Any similarities are purely coincidental)
