The instance in consciousness space has always had a limited number of entrants.
The number is determined by the strength of the invading characters' conscious power. Generally, a supervisor-level consciousness space can accommodate up to five saints for a five-versus-five power trial.
The military leader of the Annihilation Legion, Deris, had such a strong conscious power that he could accommodate twenty-five saints for a small group battle trial experience.
As the host, White Emperor did not turn on the public matching mode after invading Deris's consciousness space; instead, he set up a room matching password and invited all the players on his friend list who were online.
"Damn it? A power trial instance with a twenty-five people limit? Silly, how did you find this?"
Caramel Cook was the second one to enter this instance after Caramel. He was shocked when he received White Emperor's invitation.
