If someone were to see Shan Lingguan's actions in the Medicine King Hall at this moment, they would be extremely surprised.
Because in the three courtyards of the Medicine King Hall, there were at least two or three hundred apprentices and workers, yet when Shan Lingguan walked in, it seemed as if no one saw him at all.
This was not any Invisibility Technique, nor was it Spirit Manipulation Technique that shielded everyone in the Medicine King Hall from sensing him; it was purely Shan Lingguan's control over his own aura, which had reached an incredible level, making him almost blend into the world around him, like a part of the environment, such as flowers, grass, and trees.
With Shan Lingguan's Seventh Realm Great Martial Man cultivation, he had reached the level of 'Gang Control', using techniques to hide his breathing and presence, enveloping himself with Gang Qi and blending into the surroundings.
