Chen Mo, who stayed up late reading, was accidentally involved in a horror game from another world, and became the only chosen one who could see the red hidden hints. He was in a dead end at the beginning, and he was forced to board the No. 404 Bloody train. The bloody rules in the car threatened his life step by step: the curse of truth, the timed darkness murder, the mysterious shadow in the mirror biting people, players died tragically one after another, and despair spread wantonly.
Zhou Shen, a veteran player, pretends to form an alliance to survive, but is actually a dungeon guide who survives by sacrificing newcomers, hiding a deadly conspiracy. Chen Mo relied on his unique tips to solve many fatal situations, and joined hands with Lin Xiaoxi, a girl from the Spirit tribe, to break through the strange carriage and uncover the thousand-year-old secret of the train: the bride Liu Niang was betrayed and died tragically in a dark marriage, and resentment created this never-ending death train.
He resolved the curse of the resentful spirit with his sincerity, and successfully passed the level by winning the title of Bridal Comb and Breaker. Returning to the wasteland and seeing the human race Linyuan City, Chen Mo was shocked to realize that the horror legend of Blue Star was deeply intertwined with the secrets of the other world. His own brand of outsider hid mysteries, and a more terrifying crisis and shocking conspiracy had just begun.
