From Patrick's behavior, Silas could guess that the one who advanced to rank 7 was not Patrick. The moment the mana was out of control, Silas could sense that Patrick was only at rank 6 and not rank 7.
"So it's not you, Granduncle," Silas murmured in a low voice.
Then who?
"Even if I want to, I have to get out of this formation in advance." Patrick laughed. "My attainment in formation is not very good."
Not many people have good enough talents to practice formation and Patrick was included among them. If he had to say, his attainment was not very good and could only be considered to be relatively worse.
It was because of this that they were confident to lock Patrick in this formation all these years.
If Patrick wanted to get out, he had to break the formation.
It would definitely attract attention.
