As a cultivator of the Marginal Path at the Return to Void stage, Chen Yanqi's studies were extensive and varied. In addition to the most basic cultivation techniques and fire-related divine powers, he also mastered the Hundred Arts of Cultivation—particularly artifact and elixir skills, having reached the Fifth Rank Realm.
After sorting through it all, Xu Yang found that aside from some ancient methods that were too damaged to comprehend, the most valuable was Chen Yanqi's lifebond technique—the Nine Dragons True Scripture!
This was a fire-attribute cultivation technique that integrated many aspects into a cohesive system, which included cultivation skills, art skills, divine powers, treasured strategies, and formation principles. The cultivation technique could reach as high as the Seventh Rank Integration Realm, and the treasured strategies and formation principles could reach the Sixth Rank.
This was a legacy second only to Mahayana Skills within the Marginal Path sects.
