Hmm, in this chapter, I will add and clarify the comparison between the cultivation levels of any world Woochin goes to and the world of Primal Chaos, and I will update it with each new world.
Anyway, let's start
-------------
Comparing the world of wu dong qian kun:
Nirvana realm up to the sixth stage = Earth Profound Realm
The Nirvana realm from the seventh to the ninth stage = the Profound Sky Realm from the first to the third stage
Life realm = Emperor Profound Realm
(Yes, the difference is very big between the world of nirvana and the world of deep life)
Death Realm = Tyrant Profound Realm
Samsara = Sovereign Profound Realm
Reincarnation Realm = Sacred Origin Realm
The realm of the ancestors = the realm of the sacred self
Dimension Master = Holy Tribulation Realm

Comparing the world of Genshin Impact
First there are the immortals: whose strength ranges from the Sovereign Profound Realm (9) to the sacred Origin (10) realm.
Then there are the Seven Rulers: whose power lies mainly in the world of the Sacred Self (11)
Also, as you can see, there are strong monsters in genshin, and there are also strong humans, and their strength is estimated according to their strength relative to the previous two categories.
