The division of realms in the Ze Tian Ji (Perfect World) universe is as follows: an introduction to the classification of realms in the Ze Tian Ji world. Note: "Ze Tian Ji" is sometimes translated as "Perfect World," but it's more commonly known by its literal translation, "遮天" (Zhē Tiān), which can be translated as "Veiled Sky" or "Heaven's Veil." The exact translation for the title may vary depending on the context and official localization. For the purpose of this translation, I've kept it as "Ze Tian Ji."

Generally speaking, cultivation stories usually focus on refining people, but the worldview of the game "Perfect World" seems a bit different. It emphasizes the character's comprehension of different realms, not of people, but of the world, transcending between reflection and counter-narrative. How are the realms divided in the Perfect World? After a fortuitous coincidence, the character played by the player meets a high-level expert from outside the North Star galaxy, which then initiates the cultivation journey through the star domains. Under such a cultivation realm division, what specific realms will there be?

After players enter the game, they initially have no realm. Only after unlocking various gameplay features can they start breaking through realms. The game specifically has the following realms:

1. Sea of Wheels Realm, this is the cultivation of the navel wheel sea, opening up the bitter sea, cultivating the life spring, setting up the divine bridge, and reaching the other shore. Therefore, this realm is further divided into 4 smaller realms: Bitter Sea, Life Spring, Divine Bridge, and Other Shore.

2. Dao Palace Realm, this is the realm of cultivating the five viscera, namely the heart's divine storehouse, liver's divine storehouse, lungs' divine storehouse, kidneys' divine storehouse, and spleen's divine storehouse.

3. Four Extremities Realm, this is the realm of cultivating the limbs.

4. Hualong Realm, this involves cultivating the spine, allowing one to transform completely and begin to transcend the mundane, marking a small success in cultivation.

5. Immortal Terrace Realm, this is the great realm of truly cultivating one's mind and nature. Each small realm passed consumes a large amount of cultivation, so this realm is divided into 9 minor steps.

6. Red Dust Immortal, upon reaching this realm, one basically achieves the state of silent years, capable of traveling between star systems, and formulating the celestial rules between heaven and earth.

In the game, to quickly improve and break through realms, mainly relies on main quests to gain a large amount of cultivation points. After unlocking dungeons, grinding them is also a way to break through realms, although it mostly results in the drop of items.

The above is the sharing of how the realms are divided in the Perfect World. This cultivation story tells of characters first accumulating cultivation to initiate self-cultivation, then transcending the natural world, focusing more on the exploration of rules and the universe. "The path of non-beginning ultimately leads to emptiness" is actually the core idea during the process of realm breakthroughs in the game.
