There are four mortal realms:
Elementary profound realm(1-9):
Strength, speed, and senses above normal living beings. For comparison, take captain America level of strength, but a bit more, and for each level increase, power increases overall. This level would take vitality to activate profound energy at first, but they will recover the lost vitality with cultivation. Though, you would get a few extra years of lifespan if you exercised properly before activating your veins.
Nascent profound realm(1-9):
Profound strength develops at this stage. People are eligible to write seals with their profound energy at this stage.
True profound realm(1-9):
At this realm, the symptoms of young master syndrome develops, and they start to get arrogant due to being drunk on power.
Spirit profound realm(1-9):
Average young master power level. Weak compared to other powerhouses in the mortal star realms, but quite high in some regions.
Earth profound realm(1-9): Lifespan increases to 150 years.
At this realm, you would be called a true cultivator because, you broke your shackles that held your lifespan to 150 years. Though, this feat can be achieved by eating herbs, doing martial arts, and meditating like Li-Ching Yuen(an actual person irl. Search him up.) and live for 256 years like him without any cultivation. If earth profound cultivation is added, then 300 years.
Sky profound realm(1-9):
At this realm, cultivators can use the profound floating technique an fly. These cultivators are revered in the mortal realms as strong cultivators. At this realm, one can survive without food or drink for a year.
Emperor profound realm(1-9): Lifespan increase to 500 years.
Those who reach this realm can use Profound Floating Technique and fly in the skies unhindered. At this level, one can survive without food and drink for a year with no problems. If one follows the Li-Ching yuen lifestyle, they can live for 650 years no problem, and do note that they don't need to eat at this stage, but if one decides to continue to eat, then they would not need the extra profound energy needed to maintain bodily health. That extra profound energy could be used to further boost the lifespan to 700 years easily.
Tyrant profound realm(1-9): Lifespan increased to 1000 years.
Those who reach this realm are referred to as overlords. At tis point, lifespan can be further increased by following a normal diet till about 1400 years.
Sovereign profound realm(1-9): Lifespan increased to 2000 years.
Cultivators at this realm are able to create pocket dimensions which can store their items instead of using a storage ring. Lifespan can be increased till 2500 by following a healthy diet. This is the peak of mortal achievement.
=========================================================
There are seven divine realms:
Divine origin realm(1-9): Lifespan increased to 10,000 years.
Those who reach this realm are called profound gods by cultivators form lower realms. Vital energy is refined at this stage. It is technically possible to increase lifespan if people can grasp ki energy in ATG. Lifespan can be increased to 10,700 years with a normal diet and exercise, and with ki manipulation, if possible, can be increased to 20,000 years.
Divine soul realm(1-9): Lifespan increased to 20,000 years.
As the name suggests, it is literally when the soul deficates and removes obstacles in the mind. People can technically grasp laws at this stage, but no one is ingenious enough in the whole primal chaos dimension to do it without the help of inheritances left by gods. Lifespan can be increased to 30,000 years with other means.
Divine Tribulation realm(1-9): Lifespan increased to 30,000 years.
In this realm, there is only the growth of profound strength. Because 60% cultivators perish in this realm while crossing the Divine Tribulation, this realm is also called Divine Perishing Realm. Tribulation lightning can technically be caught with powerful formations and forged into a weapon, but on one in the primal chaos dimension thought of doing that. MC will be the first one to introduce a company dedicated to building formations to harvest tribulation lightning. Lifespan can be extended to 40,000 years max.
Divine spirit realm(1-9): Lifespan increased to 40,000 years.
Spirit deification. Lifespan max increase is 50,000 years. Laws are easier to grasp at this realm.
Divine king realm(1-9):
Realm king in a low rank star realm.
Divine sovereign realm(1-9):
Realm king in mid rank star realm.
Divine master realm(1-9): Lifespan increased to 50,000 years.
Realm king in high rank star realm.
=========================================================
True god stage from ancient era:
Divine extinction realm(1-9): Lifespan increased to 100,000
This stage is considered to be half step to true god.
True god realm: Lifespan increased to 1B+ years
A true god is a divine being with supreme power and billions of years of lifespan. There were many true gods that existed in the ancient era, but they all died or disappeared due to myriad tribulations spelling the end of the primordial era.
Creation god realm: Lifespan increased to 5B+ years
Cultivators who have reached this realm can surely live for more than 5 billion years, but none have reached the natural end of their lifespans due to the event that caused the end of the Era of Gods.
Ancestral god realm:
Cultivators have to master all the laws and/or the law of nothingness to reach this stage(The more laws you master, easier it is to progress in the law of nothingness.) At this stage, the cultivator becomes the supreme existence of primal chaos dimension.
Unknown:
Nothing is known beyond Ancestral god stage, but the guess that can be made is that the cultivator is able to consume the void and increase the strength of the whole primal chaos. this stage could also be considered as a continuation of ancestral god stage where it becomes increasingly easier to grasp the law of nothingness and control the dimension.
Unknown outer god Azathoth:
A hypothetical realm where ancestral god powers transform into outer god like powers seen in Cthulhu mythos(I mean Azathoth where he dreams up reality). In this stage, a cycle of creation and destruction of multiple dimensions in primal chaos is defined by sleep and wake up schedules.
Unknown multidimensional true outer god
Full control of primal chaos dimension, and other sub-dimensions added to it where the cultivator is omnipresent, omniscient, and omnipotent. the cultivator can choose to divide his consciousness to experience a normal life while still keeping a form of his in the omni-state. At this point, the cultivator does not require anything, or desire anything. His state is full of bliss, at all times, and it keeps increasing(this is unimaginable y mortals like us. God does not need to enjoy anything, because be defines enjoyment, and how much he enjoys.)
