Immediately afterward, Yuan Yan and his Three Corpse Dao Bodies temporarily set aside their own cultivation and devoted themselves fully to helping Yuan Jie, Yuan Lun, Yuan Ling, and their Three Corpse Dao Bodies break through.
Thus, forty or fifty Epochs ago, Yuan Yan, Yuan Jie, Yuan Lun, and Yuan Ling had all cultivated to the Peak Late-Stage Primordial Golden Immortal, on the verge of breakthrough at any moment. Their Three Corpse Dao Bodies had likewise broken through to the Late-Stage Primordial Golden Immortal.

Perhaps his foundation had already become sufficiently profound, or perhaps the various enhancements had elevated his comprehension to an utterly terrifying level. In merely five or six Epochs, Yuan Yan perfected his Yin-Yang Dao to the level of Primordial Golden Immortal Fullness.
