In the Dungeon, She Relied on Her Mouth to Survive Until the End

After the heroine Shen Zhiwei woke up, she found herself trapped on a subway train that could never reach the end. There were twelve passengers in the carriage, and the radio announced: "Please find the dead people in the car before reaching the end. If you answer wrong once, one player will be erased." She soon discovered: All claim to be alive; At every stop, there's another body; The ticket in her hand said "Terminal Station: Shen Zhiwei"; The monsters in the copy seemed to know her.
