'Is he going…to the Myriad Abysses?' Analyzing the situation, Taotie came to the only possible conclusion—a conclusion that left her shaken and unnerved. Throughout the Three Realms, only a handful knew that, within the Manuscript of Forbidden Secrets, an ancient and terrible world resided.
About 15 times the size of the Extreme Plateau, that world had appeared alongside the Manuscript and concealed a myriad of ancient evils, prisons, calamities and nefarious entities that, if unleashed, could cause the destruction of the Three Realms.
Yes—not just the Mortal Realm, but the Three Realms as a whole wouldn't survive the rampage of those creatures.
When mortals talked about "hell," unbeknown to them, they were referring to the Myriad Abysses' prisons. Places of corrupt madness and extreme horror that confined their victims to eternal suffering. Taotie didn't care about those prisons or calamities, rather dreading the ancient evils and nefarious entities sealed in the Myriad Abysses.
