The Bone Flute Underground

Lin Yanqiu, a restorer of ancient books, Chen Mo, a discharged soldier, and Zhou Ye, a member of an engineering crew, team up to explore an ancient Warring States tomb. The discovery of an ancient bone flute shatters the silence: its eerie notes awaken the supernatural forces inside the tomb, and the team members begin falling into hallucinations as one bizarre event follows another. Later, when Liu Meng from the criminal investigation team joins them, they discover that behind the unsolved cases lie not only the shadows of human greed, but also a horrifying curse spanning a thousand years and supernatural forces beyond explanation.
