Houtian life form: lifespan of one hundred years.

Xiantian life form: lifespan of two hundred years.

Zifu cultivator: lifespan of five hundred years. They absorb the primordial Qi of heaven and earth, and open up a void in their Dantian (energy center), hence the name "Zifu" (Purple Palace) due to the purple Qi that surrounds the void. The Zifu void can be used for storage.

Wanxiang True Person: They vaporize the Zifu Yuan Sea (source of energy) and use massive amounts of Yuan power to condense the sun, moon, and stars, sensing the stars of the outside world, evolving into the myriad phenomena of day and night, and focusing on cultivating their divine soul to generate divine sense. Wanxiang lifespan is eight hundred years.

Yuanshen Daoist: Yuanshen Daoists form the Turtle-Snake Yuanshen, open their celestial eye, control divine consciousness, and can split a second Yuanshen. Theoretically, their lifespan is infinite, but they will suffer the Three Disasters and Nine Tribulations (in the original work, a minor tribulation every three hundred years, and a major tribulation every nine hundred years), unless they become a Celestial Immortal, it continues indefinitely.

Fanxu Earth Immortal: They form a Golden Lotus Yuanshen on top of the Turtle-Snake Yuanshen. Theoretically, their lifespan is infinite, and they are subject to the Three Disasters and Nine Tribulations. When they reach the Fanxu Completion stage, they will suffer the Four Great Heavenly Tribulations: Wind Tribulation, Fire Tribulation, Lightning Tribulation, and Heart Demon Tribulation.

Those who fail to survive the tribulation but live on are "Loose Immortals" (their strength is comparable to Earth Immortals, and those with extremely high levels of understanding of the Dao can be comparable to the most ordinary Third-Rank Celestial Immortals). Success leads to becoming a Celestial God or Celestial Immortal.

Celestial Gods and Celestial Immortals: They jump out of the Three Realms, are no longer within the Five Elements, are free from the Three Disasters and Nine Tribulations, circulate through the Three Realms, attaining merit, longevity, and carefree existence. They must comprehend at least one complete Minor Dao.

From Celestial Gods and Celestial Immortals to the Four-Step Dao Lord, their lifespan is 108,000 Chaos Cycles. The original work does not specify how long a Chaos Cycle is (but it mentions that half a Chaos Cycle is tens of trillions of years; I personally estimate one Chaos Cycle to be 129.6 trillion years).

Note: Celestial Gods and Celestial Immortals are the same realm, but when cultivators of the Qi refining path break through the mortal realm and achieve Celestial Immortality, they are divided into three levels. First-Rank Celestial Immortals use the power of a Great World to condense their Golden Core, equivalent to a Celestial God. Second-Rank Celestial Immortals use Chaos treasures to assist in condensing their Golden Core, equivalent to the threshold of a Celestial God. Third-Rank Celestial Immortals use a small amount of their own power, and are completely slaughtered by Celestial Gods.

True Gods and True Immortals: The Qi refining path is also known as "Pure Yang True Immortal." The most important thing is to comprehend a Grand Dao, and secondly to comprehend five Ordinary Daos belonging to the Five Elements, namely the "Five Qi in the Chest."

For the path of Gods and Demons, the most important thing is to refine a perfect divine body and comprehend a Grand Dao, and then use the "Dao" as the core to build a more powerful divine body, using the transformation of the core to draw power from the Chaos, making the divine power more pure.

Ancestor Gods and Ancestor Immortals: They need to comprehend a complete Heavenly Dao and have the ability to open up a Great World.

Note: Because the quality of the Golden Cores of Qi refining cultivators in the Three Realms is only Third-Rank (so the value of Qi refining techniques is not high), the Three Realms divides Ancestor Immortals into: Ordinary Dao Ancestors who are only equivalent to the strength of First-Rank True Immortals (so True Gods are also called Dao Ancestors); Top Dao Ancestors who approach the strength of Ancestor Gods by improving their understanding of the Dao; Leaders whose strength represents the level of Ancestor Gods.

The above is the realm division of the Desolate Three Realms part. Subsequent updates will continue as they are written.

In addition, because Desolate Era mentions Earth and says that the limit of the Speed Heavenly Dao is the speed of light, assuming the Chaos World corresponds to the universe, and then deducing that the Great World corresponds to a galaxy, and the Small World corresponds to a star system (these are just simple correspondences, there is no need to substitute them, and the world level will be divided in detail later to unify the levels).
