Zhao Yuanzhen was still preparing to deal with the last wave of Tribulation Thunder, unaware that the cultivators outside were in an uproar, and no one was paying attention to her Tribulation anymore.
The large-scale disappearances of people inevitably caused panic. The explanation given by the Yin Yang Bureau is that there were non-registered civilian Onmyoji illegally conducting "Divine Concealment", which led to a large number of nearby residents being affected.
Divine Concealment, a unique "Core Formation Heavenly Tribulation" to the Chongying Onmyoji. Once the Crossing Tribulation begins, the Onmyoji will vanish from this world and enter an unknown domain to face unknown challenges.
As to what these challenges are, Lu Country has no way of knowing. For now, they only know that if the Onmyoji fails, they will completely disappear, never to return to this world.
