The Record of Returning to the Ruins

In the world of Guixu after the "Calamity of Spiritual Silence", the spiritual energy is violent and there is a gap between immortals and mortals. The path of spiritual practice is full of distortion and madness, and the truth is often more deadly than evil. Su Yue, a former deacon who was exiled by the Immortal Sect, now runs a small detective agency in a mortal town. She has no intention of cultivating immortality, she just wants to rely on her innate "Heart Trace Appearance" technique, which can see the remaining obsessions of all things, to find cats and dogs, mediate disputes, and barely survive. Until a strange cat-hunting request led her to an abandoned old house outside the town. An incomprehensible shadow of blasphemy lingers in the cat's memory of fear. Immediately afterwards, the watchman in the town died suddenly. His face was filled with extreme ecstasy, but blood crystals were condensed between his eyebrows - all emotions and memories seemed to have been completely drained away. Mortal murder? Or a twisted practice? When Su Yue touched the corpse, she only felt a void of "heart traces". The clue points to a down-and-out pharmacist and a kind of "forget-you grass" that is supposed to calm the mind. She gradually realized that this was not a simple crime, but that someone was stealing the purest emotions of living beings and refining them for their own use. Underneath the peaceful town, undercurrents began to surge. Su Yue's investigation not only touched upon the murderer's twisted desire, but also vaguely revealed the truth behind her expulsion from the Immortal Sect, as well as the taboo mystery about "mind" behind the depletion of spiritual energy in the Guixu Realm. When the cornerstone of the world is built on plunder, how can the only detective who can see through the "scars of the heart" uncover this most primitive crime in the cracks between immortals and mortals?
