Lu Qingyu, an intern reporter in the world of immortality, embarks on a path to the truth that is blocked by rules and taboos in order to trace the mysterious disappearance of his master at the end of Line 13 of the Spiritual Vein three years ago. All the clues were artificially tampered with, and those who knew about it were silent. The only one who was willing to speak was the transparent female nun in white in the last car of the last train - she looked like the Master's female disciple who disappeared back then. The talisman she left behind only read one line: "The tunnel at the end of Line 13, see you when the spiritual pattern lights up." When Lu Qingyu finally waited until the night when the spirit pattern was illuminated, he discovered that the mysterious monk who had been following him was actually an old friend of his master, and what was sealed deep in the tunnel was a thousand-year secret that could overturn the entire Lingxu. Some truths are more cruel than forgetting.
