Most solo bullet ants were 3rd or 4th rank mutated creatures. There were very few 5th rank bullet ants in colonies, and 6th rank bullet ants would be kings of a colony. This was just a small army out of the whole host of bullet ants, and only one 5th rank bullet ant was present. However, this had already scared off the 6th rank mutated Chromatic Dragon. As it ran away, its body swept up a giant cloud of dust; Wang Zhong's scent mixed into its scent when it passed him by. Compared to a human that was merely an appetizer to the bullet ant army, this enormous Chromatic Dragon was obviously the main course.
The bullet ant army changed its direction and chased after the 6th rank mutated Chromatic Dragon, eventually disappearing in the desert.
