What Qin Fengming was using at this moment was the secret art for controlling magic treasures that he had originally obtained from Gu Changtian's memories. It was also the secret art that Qing Zhu had once given him as a method for controlling the Void Stone.
This secret art had always been treated by Qin Fengming as a secret never to be passed on.
According to Qing Zhu, this art was not something that had been handed down. Even a million years ago, only a handful of people had known its details.
After such a long passage of time, the cultivators in the Cultivation World who knew of it were naturally even fewer.
Moreover, this art was the closest to the source runes of the Immortal Realm. It looked simple, but without a foundation in Immortal Realm runes, it was impossible to comprehend the hundreds or thousands of variations and combinations within it.
Immortal Realm runes looked simple, but completely comprehending them placed extremely harsh demands on a cultivator's talent for runes. Furthermore, the source runes of the Immortal Realm possessed the power to assail a cultivator's soul.
Thus, this secret art for controlling magic treasures from the Immortal Realm had gradually vanished from the Cultivation World.
Now that Qin Fengming wanted to obtain the Profound Purple Sword hovering in midair, this Immortal Realm secret art for controlling magic treasures was naturally his first choice.
However, as streams of treasure-controlling runes flashed into existence and wrapped around the purple longsword hovering in the air while it resisted the slashes and chops of sharp blades, Qin Fengming was astonished to discover that as the profound runes appeared, the two sharp blades shooting toward him suddenly veered off course. Guided by the runes moving against them, they shot toward one side instead.
