Belief is indeed a fascinating thing.
Due to Shintoism's animism, Fusang has left a bit of soil for the survival of many mountain spirits and wild monsters in the context of the great retreat of mythology.
If this were Europe, all the tree spirits, immortal spirits, fairies, etc., would have declined and perished.
The role of nymph fairies in Greek mythology was quite significant. They were subordinate divine maidens, hidden in mountains and rivers, but they gradually disappeared before the Common Era. However, now it's the 9th century AD, and Fusang still has a soil for mythical creatures to live in, even managing to pull off the Night Parade of Hundred Demons during the Heian Era, with mountain spirits and wild monsters dwelling everywhere.
Similar belief systems, like Celtic beliefs, only lasted until around 100 BC.
Their ritual stones were used for worshiping natural spirits.
"This way, my lord."
"Please follow me."
