That curse was the very reward given when he pretended to be Jiang Yitian to rescue the Sleeping Giant Emperor.
Inside, it contained a complete Sleeping Curse.
No one had expected that the deceased Sleeping Giant Emperor would leave behind a curse, let alone that it would fall into Jiang Fan's hands.
Ghost Sun Inferior Sage and Yun He Inferior Sage were caught off guard and were immediately overcome with drowsiness.
However, Yun He Inferior Sage was indeed a Soul Master, with a very strong soul and an immunity to similar soul-level attacks far beyond ordinary people.
The moment he was struck by the curse, he awoke immediately and decisively ran away into the Void with the Bone Tube.
Ghost Sun Inferior Sage was not so lucky and suddenly fell into a stupor.
Though not completely unconscious, his consciousness was sluggish.
Dongfang Canyue, as an old Sage who spanned millennia, couldn't miss this perfect opportunity.
