"The Stone of Insight that we use is known as the Inferior Stone of Insight, and it can only detect Soul Depth of 9.0 and below. That is to say, we can only check the Soul Depth of one below the level of a 3-star master teacher. Once it exceeds that level... the Stone of Insight will crumble."
Pavilion Master Jiang nodded as he pointed at the powder on the floor. "Otherwise, given how resilient the Stones of Insight are, how could it possibly shatter upon contact.
"Now that you speak of it, it does make sense!"
Everyone was stunned once more.
As a precious jade, the Stone of Insight was extremely tough. It would be difficult for even a sword to leave a mark on it. Yet, it crumbled upon contact. The situation was indeed bizarre.
"Pavilion master means to say that... Zhang shi's Soul Depth is possibly... above 9.0?"
Catching the gist of the other party's words, Elder Zhu said in a quivering tone.
What did 9.0 mean?
