When did Chen Mobai discover that Du Mengyun was no longer Du Mengyun?
From three perspectives.
First, when he used the Void Secret Technique to transport Du Mengyun, the power consumed far exceeded that of a Nascent Soul Cultivator.
Second, when he captured Du Mengyun back, the Heavenly Blessing actually sounded an alarm. Although it was relatively minor, no matter how powerful a Nascent Soul Cultivator was, even if holding a heavy treasure, it couldn't pose a threat to Chen Mobai.
And finally, the third point, was that the Primordial Demon Talisman he had originally planted in Du Mengyun's Sea of Knowledge at the Purple Mansion began to proliferate. It multiplied from one into many, distributed throughout the Five Continents and Four Seas, each corner of the Tianhe Realm.
At first, Chen Mobai didn't understand what was happening. It wasn't until he finished reading the Incarnation Demon Technique that he instantly understood.
