Wrong Ghost at Work Station

Pei Nian died the day before becoming a full-time official. Then she was "reborn". With the workplace memories of three years in her previous life, she started over - avoiding every pit, countering every backstab, and sending those who forced her to death one by one into the traps they dug themselves. Everything went smoothly. It was as smooth as if someone had paved the way for her in advance. Until one day, she heard a chanting sound at 1:23 in the morning. That's not her memory. That's not the sound this world should have. Pei Nian finally began to doubt - was her "rebirth" really just a rebirth?
