Deep beneath the Sand Demon Realm, a being in the Heavenly Immortal Realm stood guard.
With cultivation in the Void Insight Realm, stealing the innate Wu Earth origin qi was almost impossible.
Lin Fei and the Demonic Womb Clone communicated through their souls, discussing a plan.
"First, we must find out exactly what that Heavenly Immortal Realm being underground is. Only by knowing ourselves and our enemy can we prescribe the right remedy."
"At the same time, expand the search and see how much innate Wu Earth origin qi there is beneath the Sand Demon Realm."
"We cannot let such a heaven-sent opportunity slip away, but we cannot rush either. We must work toward it patiently."
Following Lin Fei's instructions, the Demonic Womb Clone once again sent two early Void Insight Realm demon souls underground to investigate.
He did not neglect the investigation aboveground either.
He likewise sent out two early Void Insight Realm demon souls to scout in all directions, using their ability to slip into the void.
In less than a month, they had uncovered almost everything about the Sand Demon Realm.
One of the early Void Insight Realm demon souls even found Lin Fei's Spirit Body, successfully joining up with him.
"Throughout the entire Sand Demon Realm, that is the only deposit of innate Wu Earth origin qi underground. However, many powerful Sand Demons are hidden beneath various locations, including some whose strength surpasses the Human Immortal Realm."
"When ordinary Sand Demons are injured fighting cultivators, they burrow deep underground to replenish their Wu Earth energy and recover their strength."
"There are more than three thousand cultivators in the Sand Demon Realm. Most are Void Insight Realm Spirit Bodies, with some Spirit Transformation Realm cultivators among them."
These three thousand or so cultivators formed three major factions.
