The Hidden World is actually a powerful Formation left on Earth by former Martial Arts Experts. This formation, a self-contained small world, possesses its own circulating Magic Law, and at the Array Eye of this formation, there's a Treasure exuding a terrifying aura!
This information was obtained from Roma Vulcan, who, for many years, had been enduring humiliation in hiding, letting everyone drop their guard against him. Only now did he act, consecutively killing Indian Solomon's Pusuo Sect Leader, the Vatican's Pope, and the Clan Leader of the Zeus Family in Greece, because he discovered a way to explore the Hidden World clearly. That was by having the other strong figures of the Mortal World, already connected with the Magic Law of the Hidden World, all die. In this way, the Magic Law of the Hidden World would be shaken and changed, allowing him to seize the terrifying Treasure!
