Du Mingxu hesitated in place for a moment before deciding to explore the Miao Lei Region.
The Dharma Origin Sect's True-Teaching Elders can only be held by True Immortals, and if one were to break through to the Profound Immortal Realm, these True-Teaching Elders would be promoted to Core Elders.
Every hundred years, some of the peak True Immortals among the Dharma Origin Sect's True-Teaching Elders will enter the Miao Lei Region to cross the Profound Immortal Calamity.
The reason for Du Mingxu's worried expression was that whenever Dharma Origin Sect's True-Teaching Elders entered the Miao Lei Region, it would provoke an ominous stir within a dark organization ensconced within the Dharma Origin Sect called 'Black Yama'. The organization would send peak True Immortal assassins, being Robbing cultivators, to rob and kill the True Immortals of Dharma Origin Sect after they had crossed the Profound Immortal Calamity.
