Who Exactly Is This Group Owner?

“Daoist Lin joined the group chat.” “Daoist Simu joined the group chat.” “Ma Xiaoling joined the group chat.” After glancing at the members, all big shots in the worlds of mysticism and Taoist arts, Xue Yi happily struck up a conversation with them. Xue Yi: Daoist Lin, have you caught up with Mr. Ren yet? Daoist Lin: How do you know? Xue Yi: I also know that after Mr. Ren turns into a zombie, blades and bullets can't hurt him and spells don't work, but he likes listening to music... And Daoist Simu, you lost a magic duel to Master Yixiu and drank a whole vat of lamp oil... Ma Xiaoling, you're dating a zombie... Everyone in the group was stunned. Who on earth was this group owner, and how could he know everything?
