Isnt noble bright world just your common cultivation fantasy?
No, Cultivation world is pretty much an easy Grimdark world.
There is no "pretty surface", as the world has gone terribly wrong since the existence of "Cultivation".
Any human and animal without cultivation, is just a "Mortal", which is the Majority of people who can't cultivate.
"mortal" are worse than animal. For reference, "Mortal" is far worse position in comparison to ant vs human, in which ant could still hurt human with its small sting, mosquito with their bites, bear with their claws, and elephant with their big leg could stomp human.
"Mortal" couldn't pose any physical threat whatsoever to cultivator, as they're just like slow walking flesh that cultivator could kill, torture, eat, and bed as they please.
Every "Mortal" knew that fact and accept them as fact of life. And therefore, every "Mortal" are scared-to-death of cultivator like a kid being scared of monster.
The only reason most Cultivator cares about Mortal is because majority of Cultivators were born as Mortal who lives in normal Mortal villages/town/cities, and cultivating from their Mortal days until they got hired by sect/mercenary/imperial guard.
And also because Sect get majority of their disciples from Mortals in their territories.
They have huge incentive to care about Mortal, as huge amount of mortal genocide equals to less future disciple, and therefore less member.
Less member equals to less power against other sect, and other province.
Cultivation world are so badly grimdark, that no serious writer would write anything other than MC who have progresses with "cultivation" just to progress the story without MC being considered "weak" and "useless" like a "mortal".
