After making some discoveries, Sang Que and Xia Chan did not continue to explore further.
In response to the chaos of zombies and ghosts attacking the base, the only solution Sang Que could think of was to use her own Ghost Realm to transform the area around the base into the Death Domain, and deploy the zombies from her painting to patrol the area.
In this way, unless they are highly targeted and extraordinarily powerful, zombies and ghosts will generally avoid approaching the Death Domain.
The matter of finding the 'Impermanent Bureau' cannot be rushed; opening the Qian Trigram Eye only reveals a large door where Black and White Impermanence can immediately detect her spying, so thorough preparation is necessary before investigating.
From the reaction of the Yin Child and this corpse, it seems this Impermanent Bureau is likely a place where evil ghosts are artificially created, where Yin Walkers are made, and serves as a site for researching supernatural entities.
