A joint expedition leads to an exploration deep underground, where the world below is strange and eerie. There is more down there than darkness: there is also a terrifying green glow. Suspended coffins in caves, bronze coffins, cat-eyed green snakes, green-eyed people, a formation of a thousand coffins, and ghostly walls that make you go around in circles. My buddy Ma Lou and I are drawn into an ancient mystery and conspiracy, and uncover the secret of eternal life hidden here. But it is all just one enormous hoax. With danger closing in, can we make it out alive?
