The people of the Netherworld were very smart.
In fact, the ghostly yin spirits had many weaknesses; they not only feared extreme yang and rigidity, but also feared extreme yin and death.
So when they cultivated the Undead Ghost Qi, they used eighteen thousand Extreme Yang creatures and stored them in the depths of their spirit bodies, thus achieving a balance of yin and yang, making it difficult for ordinary people to break through.
This was also the reason why even these ghostly yin spirits, with the protection of Dao Intent Inscriptions on their bodies, needed to cultivate Ghost Qi. With Ghost Qi, they would have no weaknesses.
However, this so-called lack of weaknesses was based on the effectiveness of the Ghost Qi.
If the Ghost Qi could be broken, these ghostly yin spirits would not be so terrifying.
Yang Chen fell into deep thought and began to ponder this issue.
If he could break through the Undead Ghost Qi, it would be a huge breakthrough.
