I'm the Only Living Person in This Chat Group?

An ordinary person, Gao Tian, accidentally joins a ghost chat group. The group members' names are all very strange, like “Ghost Infant,” “Ghost Cave,” “Living Human Apartment,” and “Burnt Ghost.” They often discuss bizarre and thrilling horror stories, and occasionally send out some black red packets. The red packet names are even more grotesque, “Supernatural Item,” “Cinerary Casket,” “Spirit-Sucking Pot,” “Blood Shroud”… Gao Tian never paid it any mind. One day, a group member suddenly said: “Among the dozens of us ghosts, it seems a living person has snuck in.” — Description from novelcodex.org
