Ch 165: Position in the Sect
The supervisor first told Rein that the Divine Scale Pavillion was first named Steel Scale Pavillion by the founder of the sect. The founder himself had the steel scale skill and the student he took in also had the same skill as him. He was the one who developed a cultivation art called the Vajra Strengthening Art and that exactly was the strongest cultivation method that the Divine Scale Pavillion had.
Later this method was modified by the second sect leader to be usable by other less powerful skill users and in that process obviously the power of the technique decreased a little bit. But still it was one of the strongest cultivation methods. But still this technique was most useful on the Steel Scale skill.
