In the outside world, only a few months have passed.
Yet within the Six Dao Reincarnation, these two Refinement Void Level Divine Souls have already undergone billions of reincarnations, countless times transforming into cattle, sheep, horses, pigs, dogs, and mortals, becoming emperors, beggars, officials, merchants, robbers, experiencing all sorts of lives—birth, aging, illness, and death—their original consciousness now on the verge of collapse, greatly reducing their defenses.
Now, within the Six Dao Reincarnation, Jiang Ding is already able to see some of Mud Swamp True Venerable's memories and can directly perform Soul Searching.
However, this kind of Soul Searching is extremely crude and likely unable to obtain all the information; many areas might be missing.
In fact, this is normal; Soul Searching among those of the same level is like this. Achieving such an effect is already quite a rare accomplishment.
