As he entered the mountain, an oscillating wave of nearly imperceptible spiritual strength bounced off the walls. Wei Wuyin's eyes shrunk for a moment, hurriedly executing a spiritual spell.
「Spiritual Spell: Scarlet Lingering Shadow」
This was one of the most vital spells inherent within a Core Disciple of the Scarlet Solaris Sect's set of spells. It concealed the physical body with a unique set of spiritual waves that adapted to other spiritual waves, allowing them to seem like a lingering shadow to observers.
When the wave of spiritual strength flowed through him, not being disturbed in the slightest, he heaved a sigh of relief. The Beast-Taming Sect truly lived up to its reputation as being very meticulous and protective of their secrets. If it wasn't for his Eighth Stage of the Qi Condensation Realm cultivation base, the chances of him being able to stealthily enter this base was absolutely zero.
