No, the Primordial Moon had already existed in the Fourth Epoch. The Emperor couldn't possibly have been Her...
Could it be that the Emperor had been corrupted by Her, gradually replaced by Her just like the Chained God had been replaced by the Mother Tree of Desire, becoming Her incarnation and thus being sealed beneath this tower?
Sigh, there was too little information to infer much.
As his thoughts raced, Klein picked up the Black Emperor card. His level and status instantly rose, causing the power pried from Above the Gray Fog to submit one by one.
Then, he grabbed a paper figurine, flicked his wrist, and threw it toward the Crimson Star corresponding to Miss Sharron.
The paper figurine merged with the power pried from Above the Gray Fog, rapidly expanding into a gigantic Angel with twelve pairs of twenty-four pitch-black wings, overlapping with the phantom within the crimson radiance.
Immediately afterward, that power collided violently with the red Roselle figure on Sharron's body.
At first, the crimson-colored power could still contend with the Gray Fog carried by the paper figurine Angel. But lacking follow-up strength, it quickly lost ground and was gradually "swallowed."
However, just before the "corruption" was completely removed, Klein, seated in the Fool's chair, suddenly heard a cacophony of murmurs that left him dazed.
Those murmurs originated from the corruption devoured and expelled from Miss Sharron. Through contact with the Gray Fog, they reached his ears.
Fortunately, after being "processed," the murmurs were harmless, somewhat resembling the "roars" he heard whenever he entered the Gray Fog:
"Master Key"...
"Full Moon Whispers"...
"The method given by the Calamity Seal"...
"Separating the corruption was not completely successful"...
"Beware the moon"...
"Save me"...
"Find Liu Bo and save me"...
"Do not casually set foot on the first floor"...
