That Xinzi's fusion with the Heavenly Dao and mastery of the Dao Breath multiplied his growth pace didn't surprise Qiu Meng. He'd seen that much in the various timelines, and so came mentally prepared to be no match for his enemy.
But "pace" here was the primary issue. The rate at which the Dao Breath enhanced the might of Xinzi's body, Dao Foundation and soul was way faster than it was in any other timeline — at least three times faster. The Dao Breath Alone couldn't explain this.
'He must have found a way to fuse his Five Elements Transmutative Technique with the Heavenly Dao and his Swallowing Skill — adding them all to his Dao Breath. So, this is no longer just Shenzhuo's Dao Breath, but a bridge between the Dao Breath and the Primordial Breath that Hengye Zhen will later shake the world with.' By relying on his knowledge of the future, Qiu Meng saw through the root of Xinzi's breakneck growth pace.
