"Huh? Ghosts?"
Lin Feng sensed that there seemed to be something new in his Reincarnation Realm. They were somewhat similar to ghosts, and was an invisible force that could only be captured by the Reincarnation Realm.
However, they did not seem to be ghosts,either. What the Reincarnation Realm captured was entirely energy that seemed to belonged to the soul, such as perfected spirits, ghosts, and so on. Apart from these, the Reincarnation Realm could not capture other energy.
There were very few of these "ghosts", and they were all incomplete. For some reason, they still remained in the carcasses after death. Forget about ordinary cultivators, even a Perfected Deity would not be able to detect them.
If not for the Reincarnation Realm in Lin Feng's internal universe, he would not have been able to discover the remaining power of the "ghosts" in the carcasses either.
