The Dao Heart Demon Talisman, something Ye Zhen had only read about in ancient texts before, had never been seen by him in its physical form.
Once a martial artist's cultivation breaks through to the Dao Entrance realm, the Divine Soul Oath no longer has much binding power. The Divine Soul Oath uses the martial artist's own divine soul power as a medium, so how binding could it possibly be?
Usually, only those martial artists who have condensed a primordial spirit use primordial spirit power to evoke the Heaven and Earth Laws to swear an oath, which has considerable binding power on those who swear it.
Yet still, there are many nuances involved, such as true body versus false body, and so on.
Additionally, the Demon Race evokes their Ancestor Spirit Bloodline to swear oaths, and the followers of the Heavenly Temple Demon God Palace swear by the tributed Divine Monarchs and Divine Kings, among others.
While these have some binding force on those who swear, they aren't absolute.
