Dong Tianyu flipped through the booklet he received from Robinson William, finding that most of its content was a Cultivation Method for the Inner Breath Realm. Although the method was balanced and gentle, it was not slow in practice. It was also noted that it did not conflict with most other Cultivation Methods for the same realm.
Beyond that, the final few pages of the booklet detailed how to break through from the Inner Breath Realm to the Energy Realm, the necessary level of cultivation for attempting the breakthrough, and methods to stabilize one's cultivation level after the breakthrough.
Dong Tianyu quickly finished browsing the booklet in his hand, then returned it to Madeline and casually asked, "Besides this Inner Breath Realm booklet, there should also be ones for the Body Tempering Realm and the Energy Realm, right?"
