There are many Mortal World in this novel and what determines the world to be a mortal world is the spiritual energy it produced! Once a world can only produce spiritual roots of the lowest to mid tier, it's immediately labeled as mortal world.
Immortal world on the other hand has thic spiritual energy and can produce high to highest spiritual roots if a cultovator cultivate in that world.
So the moment you are born in the mortal world, without a connection to the Immortal clan and be accepted as their outer disciples, your fate is already sealed to be a mere mortal!
To reach the Immortal realm, and start cultivating into Qi Gathering Stage, one needs vast resources but all resources are manipulated by the Immortal clans. Without a connection to them even with a heaven-defying body constitution you won't reach the Qi Gathering stage, the lowest stage of the Immortal stage!
In this novel, there is no such sects here—only Clans. Immortals here cultivate their own bloodline rather than picking up random people. If you are an exceptional mortal that you even managed to catch the eyes of the Immortals then you can marry off to that Immortal clans and be part of that clan making you their branch. Strengthening the clan more.
Every Immortal clans of this world own at least 5-20 mortal worlds.
If you're born in this world in a mortal world without connection, you're done for. Forget your heaven-defying constitution. The highest spiritual roots you can have is the lowest one! And without resources and cultivation manuals from the Immortal clans, you won't reach Qi Gathering Stage. Meaning: you're done for lol.
And Han Clan is one of the rulling Immortal clan in this world as Han Tian Yi's father is at the early stage of Saint stage, only one step lower from Dao God while his mother is at the mid stage of True Immortal stage a level only lower to Dao God and Saint Stage! Making their clan tier as a highest tier!
Immortals ranked from: Qi Gathering Stage as the lowest and Dao God as the highest one can attained (but this is just a legend since no one actually reached it yet)
Secluded domains are natural occurrence in the higher realm but it's rarely seen so not every clan own a secluded domains.
One can only be called a demonic cultivator once they threw away their morals and humanity.
Righteous cultivator doesn't mean they're kind, these people just didn't threw their humanity but since they're Immortal, they all treat mortals as bug.
Qi = used by mortals that learn martial arts. It's the lesser version of spiritual energy.
Spiritual energy = Qi with fragments of Dao itself. So by gathering spiritual energy, one can be closer to the Dao itself, the higher the realm the more dao fragments are etched deep in your body.
