After escaping from the location of the Supreme Tribulation and finding a location to hide in, Corey decided to study the distortion and manipulation of the space, time, and void around him.
Despite escaping from the location of the Supreme Tribulation, the distortion and manipulation of the space, time, and void around him followed him no matter where he went to and he could not teleport to the Neon Headquarters no matter what.
It was an application of space, time, and void that astounded him. No matter how much he observed and studied the ability, the progress he made was basically close to nil.
Although he failed to understand the ability that was used by either a Supreme or the Supreme Ancestor on him, he found out that the space, time, and void around him was being restored back to normal.
However, it would most likely take a week or so based on his calculations.
