The Ten Thousand Poison Evil Prison is among the Inner Realm Divine Domains mastered by the Human Clan and is the one that expands the easiest.
Wherever the poisonous miasma reaches, it becomes part of the dojo's expanse.
Especially after the Great Elder abandoned his human body and cast away the reasoning of being born human, there were no longer any restraints; he devoured Evil, the Human Clan, strange energies of Deceit Night... thus transforming them into his toxic barrier of evil energy. The speed at which his inner realm expanded was terrifying.
Meanwhile, Lin Yan's Netherworld Inner Realm required steady construction to avoid a fragile foundation, focusing on condensing the Inner Realm and secondary on expansion.
Therefore, Lin Yan's Inner Realm Divine Domain covered a much smaller area, unable to completely encompass the entire Ten Thousand Poison Evil Prison within his Netherworld Inner Realm.
