Just like in the original story, there was a hidden chamber built underground beneath the Divine Deer Shrine.
There wasn't anything particularly special here, just a huge Nine-Colored Deer statue and a few scattered storage cabinets in the corner of the wall.
The storage cabinets mainly contained the antlers shed by the Nine-Colored Divine Deer each year, as well as various hairs naturally shed from the Nine-Colored Divine Deer's body, or the saliva that dripped from its mouth while sleeping.
These things weren't a big deal for the Nine-Colored Deer, but for humans with weak spiritual energy in their bodies, they were like dragon eggs and jade nectar.
Apart from that, the main purpose of this huge Nine-Colored Deer statue was for the villagers of the snow village to collect the excess natural spiritual energy from the Nine-Colored Divine Deer on a daily basis.
