Hi, welcome to Nine Venoms Sect Founder's official spoiler page. Without further ado, let's get started.
Mortal Path:
Purification (150 years)
Hallowed (200)
Daoist (300)
Nihilty (500)
Crossed Vicissitude (1000)
***
From here on, this story has two cultivation paths you need to care about.
***
Divine Path (This is most relevant in the first 20 chaps, then becomes a comparison tool for the other path):
Celestial Kin (3,600)--The Mc starts here
Celestial Guard (10,000)
Celestial Knight (50,000)
Ascending God (100,000)
Heavenly God (Theoretically Immortal)
Empyrean Monarch (Theoretically Immortal)
***
Six Incarnations Bridge (Most relevant after the first 20 chaps. This is the one the mc will focus on):
Human Realm
Monstrous Realm
Ghost Realm
Infernal Realm
Asura Realm
Reincarnation Realm
***
There are others, of course, but I think for now we're good.
