Yusuf Zuck did not know how to activate the Blood Beads again; the first time was by electric shock, and the second time was during his time in America, sparked by the death of Lena Brown, so the activation of the Blood Beads lacked any pattern.
He certainly couldn't get electrocuted again, nor could he re-experience the helplessness of a loved one dying before his eyes, so he was unable to find a method to activate the Blood Beads.
Of course, he would try various methods in the future to discover the way, and once he found it, he would become a true master.
After breakfast, Fleur Carson took him to the airport early, and once there, he also found time to call Mia.
However, the call was abruptly cut off after one ring, followed by a text message: "Ignoring you, hmph!"
Seeing these words, Yusuf laughed. Mia was probably with Ruth Wilcox at the moment, so it was inconvenient for her to answer the phone.
