For example, the Soul Break on the foreign races' arrows is precisely to break through Northern Spiritual Energy, and the reason their bodies are cultivated so tough is also to resist Northern Spiritual Energy.
So does that mean using the power of the soul can break open these people's Armor?
Previously, when Ling Zhenfei used the power of the soul to attack an opponent's soul, he was basically using his own powerful soul to ram into the opponent's soul.
The strength of the power of the soul is related to one's own cultivation; as one's strength grows and improves, the power of the soul will also become correspondingly stronger.
For instance, a cultivator of the Zhu Xin Jing System is definitely much stronger than a cultivator in the Zhiyi Boundary, but since they ultimately haven't deliberately cultivated it, they naturally can't compare to Ling Zhenfei's power of the soul.
