"XIX. The Three Mysterious Tunnels
The discovered tunnels are thousands of miles in length and lead to three different areas of the planet. The one in the left connected the Romanian base to a yet to be discovered underground base somewhere in Egypt (which was definitely discovered and explored by now).
The right tunnel led to a similar but smaller structure, in the “Tibetan Plateau”. This tunnel had three secondary ramifications. One led to an underground area near the Romanian city of Buzaru (close to the “Carpathian Bend”). Another one led to the already mentioned Iraqi base, while the final ramification led to an underground base in the “Gobi Desert”, in Mongolia.
XX. The Third Tunnel — A Secret World
The middle tunnel was the most important to both Lord Massini and the U.S. Government, which strongly requested to be kept secret to the public. This tunnel descended to extreme depths towards a veritable underground world, located near the center of our planet."

"The length of the tunnel was given as approximately 1,500 miles, so it cuts through underneath both land and water."

"“Fabled Shambhallah,” as she Madame Blavatsky calls it in her book The Secret Doctrine, was an etheric city in the Gobi Desert, the invisible headquarters of the Mahatmas, a brotherhood of great spiritual masters who had moved there long ago after the submergence of the land of Mu under the Pacific Ocean."

"the Macuxi people entered a sort of cave attracted by a voice and traveling for 13 or 15 days until they reached the interior of the planet, a place located “from ‘other part of the world, in the inner earth ”, where they discovered giant and living creatures about 3-4 meters high.
According to the Macuxi, these giants were given the task of monitoring the passage in front of the entrance and preventing foreigners from entering the “hollow earth”."
