Within this area, the inhabitants of the Dark Matter World have all but completely forgotten everything about the Material Universe, believing that the Dark Matter World is all there is. Because of this, they are much more familiar with the Dark Matter World than Lu Yuanming and his group, including the locations of various Dark Matter inhabitants, the threats posed by terrible monsters, and the use of the powers of the Dark Matter World, among other things.
When Lu Yuanming slew those Super Level beings, it was ensured that in a vast area no one witnessed the act, yet the information about his slaying these Super Level beings still leaked out because the Dark Matter inhabitants employ a system of power from the Dark Matter World, akin to Psychic Power but different.
As Lu Yuanming approached the forest, all elves and other aliens in the hall turned pale.
