I won't go into detail about the Qi Cultivation Realm. The Gathering Spirit Realm is simply a preparatory realm developed by the Zhengxuan Sect to lay a foundation for the Qi Cultivation Realm.
I'd like to mainly talk about a realm that might appear later: the Purple Viscera Realm. The word 'Viscera' is intentional; it's a reference to the 'five zang and six fu organs' of Traditional Chinese Medicine.
Hence the name, Purple Viscera.
Among the 'five zang and six fu' organs, from the perspective of Traditional Chinese Medicine, the five 'zang' organs are considered yin, while the six 'fu' organs are considered yang.
The meaning of the Divine Organ Realm is also rooted in a concept from Traditional Chinese Medicine: 'the five zang organs house the spirit (shen).'
The six 'fu' organs are the warmest parts of the human body. My thinking was inspired by the proverb 'Purple qi comes from the east,' which also symbolizes the rising sun.
That's why I came to associate the color purple with 'yang,' and thus named the realm Purple Viscera.
As for the Soul Realm, my intention is to have it represent a person's character and temperament. My writing may not be skilled enough, but I will do my best to write it well.
Although there are many different realms, their power levels are all meant to correspond one-to-one. I hope everyone can understand this. I didn't want to simply name every realm using the same progression—like Qi Cultivation, Foundation Establishment, Golden Core, etc. That would feel perfunctory and wouldn't properly illustrate or represent the reasons for Body Refinement or Soul Cultivation...
