Corey had learnt a few things from Chucky, the spirit of the Perceptual Nexus Repository. One of them was about the uses of the stars in the Perceptual Nexus Repository.
The stars had other uses asides from being used as clones in the virtual reality room and as energy sources for the entire Perceptual Nexus Repository.
One of them was that the stars could help Corey multitask.
Before his baptism under the Eye of God, Corey was always able to perform two or more tasks at the same time with his mind.
Corey was obviously not the only person to be able to multitask with his or her mind. It was in fact, a very common feat as one's intelligence stat increased.
But, even though beings with a high intelligence stat could multitask, there was usually a strain on the mind of the individual.
The mental strain was dependent on the number of tasks issued to the mind, type of the tasks issued to the mind and the intelligence stat of the individual.
