The Artificial Intelligence System judges tasks based on standards from ten thousand years ago.
In the era before the Great Schism, the kingdom of Hell governed all deaths, and there was no existence of Netherworld.
However, with the Primal Chaos Realm's Great Schism, the Great Yin's Mortal Emperor reached an agreement with the Lord of Mount Tai, partitioning part of the kingdom of Hell to create the Netherworld, allowing souls of the Primal Chaos Realm to undergo reincarnation.
The emergence of the Netherworld was credited to the Great Yin's Mortal Emperor and the Lord of Mount Tai, but due to Shen Yuan possessing Emperor Fengdu's incorporeal persona and expelling the 10th Hall Yama, he unified the entire Netherworld, which led the Artificial Intelligence System to recognize Shen Yuan as the ruler of the Netherworld.
