Bureau of Paranormal Investigation - S01

While pursuing drug smugglers near the Yunnan border, a special forces team stumbles into the ancient caves of the Shu kingdom, disrupting long-forgotten rituals. The squad is nearly wiped out, with only Shen Shuang and narcotics officer Sun Desheng surviving-thanks to the intervention of a mysterious white-haired man named Wu Hao. After this ordeal, the two find themselves drawn into the "Civil Affairs Investigation and Research Bureau," where they become increasingly entangled in supernatural cases, slowly uncovering the hidden truths of an unseen world.
