Discovery under Egypt's pyramids may lead to forgotten underworld

I discovered three perfectly cut shafts hidden beneath the sands. They sit in the triangle between the Great Sphinx, Khufu's Pyramid and Khafre's Pyramid, and may open into a long-forgotten underground world. These are not water wells. They bear no inscriptions, no signs of casual digging, and their geometry is too precise, their walls too smooth, their design too deliberate. Could these shafts be the keys to the network of hidden chambers the Greek philosopher Herodotus once whispered about, possibly connected to the Nile?
