Hei Xinjiu looked in the direction that Guai Cao was pointing at and was stunned. Guai Cao was actually pointing at the black bead.
Back then, when the cheapskate grandfather gave the black bead to her, he had said that only the Yun family could make it recognize its master. At that time, it was quite incredible that she could make it recognize its master.
It was not until she returned to the Yun family that she realized that she was really a member of the Yun family.
Presumably, the distant ancestors of the Qing Xuan continent and the Yun family of the towering sky continent should be a family. That was why she was able to make the black bead recognize her as its master.
Speaking of which, the black bead did not have a strong sense of existence. Other than devouring the power of thunder and lightning, when Hei Xinjiu fell into an illusion, it would use the pain to remind Hei Xinjiu. Other than that, there was nothing unusual about it.
