The Calamity of Longevity

One day in 1989, thick smoke billowed from a remote modern health research center. Everyone inside, from its administrators to its researchers, died mysteriously and horribly, while its founder, the entrepreneur Xu Jianguo, disappeared. Thirty years later, the protagonist Xu Pei joins an outdoor research team of university professors and students, venturing into the center to find a collection of cultural relics and ancient books once kept there. He unexpectedly stumbles upon the truth behind the murders. But by then, the Grim Reaper haunting the research center has begun closing in on them.
