Gao Heyan pondered several possibilities in his mind before asking the forensic expert, "I have a few more questions. The oral cavities of the previous three victims were all stuffed with maps before their mouths were sewn shut, right?"
"Yes... The method of murder is extremely brutal."
"So, what areas did those maps depict?"
"This had always been confidential. I only learned about it after the special investigation team arrived... It was supposed to remain confidential..."
After a moment of thought, overwhelmed by the desire to survive, the forensic expert with surname Chen said, "It's at Suyuan Mountain in W City."
Upon hearing this, both Dai Lin and Gao Heyan gasped in shock.
Suyuan... Mountain???
The first time Lin Yan saw the pupil-less female ghost was at Suyuan Mountain!
"Suyuan Mountain..." Dai Lin repeated to confirm, "You mean Suyuan Mountain on the outskirts of W City?"
"Exactly, yes... Why, do you know something?"
This absolutely couldn't be a coincidence!
