First, Zhou Tian discovered that while the bead could grant its user a high level of rule mastery, the source of that mastery was entirely within the bead itself. Just as Zhou Tian possessed the rule for the same reason, he could sense that all the new rules on his body at that time were emanating from that bead. However, losing the bead meant losing all his cultivation level at that moment. The way that rule existed was already predestined, and if one fought using the cultivation given by the bead, then any ability not cultivated by oneself would certainly be difficult to operate smoothly in a key moment.
Of course, though Zhou Tian felt a variety of sensations once he used the bead, he didn't let the changes in his strength distract him. Instead, another sensation from embedding the bead slightly altered Zhou Tian's mood at that moment.
