At this point, the arena no longer bore the initially very weak skull; the skulls that remained were mostly of the larger, taller variety.
Through observing the size of the skulls in the arena, Dong Tianyu astutely realized that if the skulls died from devouring each other, then the other arenas should not have any dead skulls that were consumed. Otherwise, no matter how long they waited, the arenas would always refresh with those initial frail skulls.
Although Dong Tianyu had seen through the tricks of the Mysterious Realm, it was of no use, since he was not the only person in this realm; there were ninety-nine others. Even if Dong Tianyu understood the situation and restrained his actions,
it didn't mean that others would share the same thoughts as Dong Tianyu. Otherwise, no one would have killed that initial weak skull.
