The energy on this talisman paper had almost entirely disappeared due to the passage of time, and even Emperor Xuanwu couldn't find what was inside.
But the moment Qin An infiltrated it with Void Essence, the talisman paper finally showed a hint of anomaly.
Qin An could feel that there was a faint aura flowing inside the talisman paper, hidden in its deepest part.
If Qin An didn't have the Perfection of the No-Self Realm, he truly wouldn't have been able to sense what was hidden within this talisman paper.
This trace of energy was the energy of the Mysterious World.
Through this talisman paper, the energy from the Mysterious World seemed to set a coordinate, which Qin An could clearly feel.
"Did you feel that?"
Emperor Xuanwu also noticed Qin An's anomaly, because when Qin An sensed this trace of energy, it provided him with the most direct feedback.
