Danxia Heaven was indeed a Daoist lineage with a tradition, but its influence was truly too small.
Even within the Daoist lineage, the ancestral tablet of Maoshan was placed there; when leaders visited, they might take a look, but it was unlikely they would take it away; however, Guan Shanyue himself worried that his own valuable items might be "borrowed" by powerful individuals.
Anyhow, the individuals from Danxia Heaven would neither say where the director was located nor admit to any cultural relics being unearthed.
Nevertheless, the two officials from the cultural heritage department had done some groundwork beforehand and suggested that since you won't admit it, we'll go take a look at the back mountain.
A new path had just been built on the back mountain, and this piece of news was not particularly secret; after all, it's impossible to rely solely on the Taoist priests to do the work—local labor had to be hired.
