Just a quick list of the cultivation realms that are already mentioned in the story.

Energy Cultivation System. Despite the titles of the stages, most are just referred to as Early, Mid, or Late stages.

Ascended Tower realm. Divided into Mortal Tower, Houtian Tower, and Xiantian Tower realm. One builds up their Ascended Tower, allowing them to produce and harness Qi within their own dantian.

Heaven's Gate realm. Divided into Heaven's Foundation, Heaven's Ladder, and Heaven's Gate. One opens the gates of their Ascended Tower and climbs to the peak, tearing off the roof and connecting the tower to the heaven's, absorbing even purer Qi and starting to come into contact with the laws.

Soaring Immortal Realm. Divided into Crawling Immortal, Wandering Immortal, and Soaring Immortal. One uses the laws one has gained insight into, infusing them into one's body and slowly changing it, shedding their mortal coil and drastically increasing their life spans, while also increasing their affinity for the laws used to change their body.

Primordial Immortal Realm. Divided into Human Immortal, Ancient Immortal, Primordial Immortal. At this stage, one uses all the laws one has gained insight into and changes their Ascended Tower, turning the entire tower from a structure made from Qi into a structure made from the laws. The tower will then become a structure made from a single law, a fusion of every law that person has cultivated, a law unique to them.

Transcended Immortal Realm. After turning their tower into a structure composed of the laws, one must then completely fill it with Qi, to the point that the tower starts to shatter and collapse in on itself, the fragments floating around within a person's dantian and separating from the heaven that they were connected to.

Sovereign God realm. After the Ascended Tower has been fully shattered, the cultivator must turn the fragments of their Ascended Tower into an independent heaven that they can draw energy from, a heaven solely for them, where they can be god.

Empyrean Ruler realm.

Primeval Sovereign realm.

Universal Heart realm.

While these are the cultivation realms, the MC uses a different cultivation technique that creates lotuses based on the laws he is cultivating. These lotuses are called Dragon Lotuses, and the more leaves they have, the higher his cultivation is.

Body Cultivation System.

Bone Forging realm. One strengthens their bones using Qi to let them bear the future pressure they have to withstand.

Body Ascension realm. One strengthens their various organs using Qi, their laws, or other sources of energy. This will connect the organs to the heavens, spawning a type of energy called Fiendgod Essence, the body cultivation equivalent of Qi.

God Forging realm. This step requires one to use their Fiendgod Essence as well as their laws to pierce their own bones, organs, as well as their flesh, replacing all the Qi within them, as well as completely filling them.

Mortal God realm. This stage requires one to use their Fiendgod Essence and their laws to fully change their blood, as well as forcing open all 361 acupuncture points in their bodies.

Fiendgod realm. At this stage, one continues to strengthen every part of their body with Fiendgod Essence and their laws, slowly disconnecting their body from the heaven they are connected with, turning one's own body into an independent heaven they can draw energy from.

Star God realm. This realm can only be reached after one has fully turned their own body into an independent heaven, and there are three different ways for a cultivator at this realm to increase their cultivation. The first is by killing someone else at the Star God or the peak of the Fiendgod realm and refining their heaven into one's own. The second is to refine an entire universe into their own heaven, and the third is to refine a star into their own heaven. Of the three paths, the third one is the easiest.

The body cultivation system that the MC follows is a bit different from this one, mainly because it requires him to not strengthen his body, but rather turn his body into the purest of lightning.

Soul Cultivation System.

Materialized Soul realm. The first and easiest cultivation level. It only requires one to nourish and strengthen their soul enough to let it take form within the mind of the cultivator, greatly increasing their thinking and concentration power. The difference between the three stages of the cultivation realm is how corporeal the materialized soul has become.

Ascended Soul realm. To reach this stage, one must strengthen their soul enough to let it leave their body and allow it to connect with the heavens. If the soul has not been strengthened enough, the majesty of the heavens will shatter it, so the strengthening process is vital. Connecting the soul with the heavens will spawn something unique to Soul Cultivators, something called Anima Essence, the soul equivalent of Qi. This energy specializes in attacking the very essence of all living beings, the soul.

Soul Rebirth realm. One of the more dreaded steps of Soul Cultivation, it requires you to use your Anima Essence to shatter your own soul so thoroughly that only a sliver of your consciousness remains. You must then use the energy of the heavens, as well as your own Anima Essence, to rebuild your soul from scratch, allowing it to become purer and stronger than ever before. The slightest mistake can result in death or retardation, so great care must be taken.

Soul Lord realm. Thanks to the previous process of rebuilding the soul, it has now become so pure and strong that it can bear this step. One uses their Anima Essence and whatever laws they have gained insight into, fusing it all together and merging it into their soul. In doing so, one must fuse all their laws into a single one to control the soul, creating a law that is wholly unique to this cultivator.

Heaven's Soul realm. The realm known to be the most painful of the soul cultivation realm. This realm requires one to tear their soul free from the heavens, severing the connection between them and wresting control over one's soul away from the heavens. One must then use their own insight and understanding of the heavens to turn their soul into an independent heaven, practically becoming a god.

Universe Soul realm. The final step of Soul Cultivation, the highest of peaks in existence. One has turned their soul into an independent heaven, and now you must use that heaven to create a universe in your own image, turning your soul into the nucleus of the universe. At this step, every attack from your Anima Essence will bring with it the might of your universe.
