The Soul-Searching Technique was an exceptionally vicious form of Martial Arts. It involved forcefully searching another person's soul for their memories. How much could be retrieved was an unknown, but one thing was certain. Anyone subjected to the Soul-Searching Technique would almost certainly be reduced to an idiot. Even if they weren't, their soul would inevitably be traumatized, severely impacting their future cultivation.
With an incomplete soul, one's cultivation speed would naturally plummet, as would their aptitude. It could be considered one of the most ruthless Martial Arts in existence. However, very few people knew how to perform it. It wasn't surprising that someone from the Netherworld Empire would know of the Soul-Searching Technique; from the looks of it, they had used it many times.
