With his Bloodline QI activated, Al's sensitivity towards anything similar to flames was pushed to the extreme. He was able to sense that the silver armored ladies also possessed a bloodline QI that was a bit similar to that of Prince Curtis. However, it was weaker and diluted.
And indeed, the armored ladies do possess the bloodline of Phoenix, albeit a pseudo-Class-1 bloodline that could almost compete with a Class-2 bloodline, however, their bloodline cannot utilize the oppressive and suppressive might of an original Class-1 Primordial bloodline. It was only good for boosting their abilities without any significant side effects.
