Urban Legends: the Legacy of Ancient Civilizations

There are many secrets in urban legends, including Mayan prophecies, the unverifiable Tunguska explosion, souls, resurrected corpses, time and space tunnels, Yingkou falling dragons, UFOs, and ancient civilizations. There are too many horrors that cannot be named, and too many supernatural phenomena that cannot be proven. If you just treat it as a rumor about mountain ghosts, it would be a bit too small to underestimate the secrets and power behind this world.
