How to Enter the World of Black Matter Edit
Nothing can enter this place without getting absorbed, except for an Ultimate Iron Man. Another way of entering Black Matter without getting absorbed is to gather up the original power-users with elemental powers, but because they don't actually fit with the qualities of an Ultimate Iron Man, there is a big probability that they won't make it back to the physical plane. Once entered, they must return before nightfall, where demonic energy will gather up and block the exit. Xia Tian, Lan Ling Wang, Xiu and Jiu Wu once entered Black Matter to save Bing Xin.
