Bureau of Paranormal Investigation

While pursuing drug lords near the Yunnan border, a special forces team stumbles into ancient Shu caves and disrupts long-forgotten rituals. Nearly the entire squad is wiped out-only Shen Shuang and anti-drug officer Sun Desheng survive, saved by a mysterious white-haired man named Wu Hao. After this encounter, the two men are drawn into the "Civil Affairs Investigation and Research Bureau," where they find themselves caught in increasingly strange and supernatural events, slowly uncovering the hidden truths of an unseen world.
