Two months later.
Chu Ning had already mastered the basic theories of formation, and started studying the restrictions in Wang Sen's jade slip.
Three months later.
A jade slip appeared in Chu Ning's hand, the same one that Zheng Qingmin had on him.
Placing the jade slip in front of him, Chu Ning formed a series of hand seals with constant changes.
The seal formations Chu Ning was executing were one of the three types of restrictions recorded in Wang Sen's jade slip.
Thirty breaths later, Chu Ning's hand seals changed again.
If the first type of restriction wasn't right, then he would try the second method to break through.
For Chu Ning, he hadn't completely mastered the restrictions but had mastered the three types within the jade slip, unable to deduce the restrictions based on those within the slip, leaving him to try one by one.
