Right now, what Jessica was witnessing without a doubt was blood control. At first, she was unsure who was using it—either the little girl or the strange looking plain vampire she had seen. However, now it was clear.
Blood control was different from blood aura, which is what every vampire had. Blood aura allowed vampires to emit strong attacks such as the blood swipe, blood canon and so on.
However, Blood control was something that only the gifted vampires could do, and it tended to follow the bloodline of the vampire leaders, decedents and more could use it. Still it would vary from vampire to vampire.
With blood control, one could change the direction of their attacks and could even use it to speed up and strengthen their attacks to the next level, which was why right now, Jessica was more amazed than ever.
