The memories of these four individuals, for the most part, are nothing special.
They are merely the legendary experiences of four Demon Cultivators advancing from the Qi Refining stage to the Nascent Soul Realm.
These occurrences, in the area of influence of demonic forces, the Ghost Soul has witnessed too many times.
Therefore, He Song naturally wouldn't be surprised in his heart.
However, among these four individuals, one of them, whose cultivation had reached the late-stage Nascent Soul before death, brought a pleasant surprise to He Song.
This person was precisely the Nascent Soul cultivator who had long been at odds with the Yin Soul Sect.
The remaining three Nascent Soul Demon Practitioners were also invited by this person.
As for how this person came to be at odds with the Yin Soul Sect and why he was fixated on it, He Song found the answers within his memories.
He Song had already felt something was off about this matter.
