The Penglai Immortal Realm had no Immortal Court system, but instead was home to four great Tao Sects. Below the Tao Sects lay countless large and small Immortal Sects, which were divided into nine tiers.
Purple Sun Tao Sect was one of the four great Tao Sects, and within the boundary of Purple Sun Tao Sect, there was a ninth-tier Immortal Sect called the Dharma Origin Sect.
The place where Han Yi had once faced the Profound Immortal Calamity was within the bounds of the Dharma Origin Sect, in the Miao Lei Region.
At the time of the calamity, due to a fortuitous misunderstanding, he acquired the inheritance of the Qingyan Knife.
And this inheritance of the Qingyan Knife came from a dark organization within the territory of the Dharma Origin Sect known as Black Yama.
