Xuan Jizi felt a slight shock in his heart, aware that when such a scenario arises, there are generally two possibilities.
One is that Lu Qing practiced some Special Secret Method, capable of perfectly concealing his own aura, making it undetectable to others.
The other possibility is that Lu Qing possesses an Exotic Treasure, capable of shielding others' Divine Soul Power perception.
He was more inclined to believe the latter.
After all, Lu Qing was too young, and even if he had practiced a Secret Technique, his experience would likely be shallow.
Moreover, according to the intelligence of Tianji Building, Lu Qing was merely in the Internal Organ Realm two years ago.
Even if his cultivation had advanced rapidly, at such close proximity, he shouldn't have been able to deceive him, a seasoned expert in the Innate Realm.
Having made his judgment, Xuan Jizi then turned his attention to the elder doctor.
And with that look, he was once again taken aback.
