## Eras

The 'Nine Heavens and Ten Earths Yearbook List' book mentions modern era, ancient times, very ancient era, Primordial era, Ancient Desolate era and Great Primal Chaos Era.

* Modern era refers from the present to Million years ago.
* The ancient times refers to Million years to ten million years ago.
* The very ancient Era refers to ten million years ago to billion years ago.
* But Primordial and Ancient Desolate Era, the changes of these two Era are relatively vague and cannot be calculated by year. According to the records in books, Primordial refers to the first year of the birth of the cultivation world, so Primordial is also called Highest Beginning.
* In the Primordial Era, it is considered to enter the cultivation Era. It is said that at that time, Cultivation Technique and Battle Skill, everything is the most primordial, everything is rudimentary, and the year cannot be traced back because it is too long and everything is blurred.
* Before Primordial Era, it was Ancient Desolate Era. It was said that it was a disorderly Era. Human Race was still at the bottom of the food chain. There were no written records. Only some murals were handed down to record the difficult survival of humans at that time. In the Ancient Desolate Era, various kinds of wild beasts and other creatures are the overlords, and humans can only survive in the cracks. It can be said that human memories can only be reversed to Ancient Desolate Era, because at that time, although there were no words, there were pictures and texts to calculate history.
* Great Primal Chaos Era is a vague name, it is Era before human history. It is a piece of Era unknown to human beings.

## Primal Chaos Era

* During this era, there was abundant Primal Chaos aura and the Heavenly Dao laws were complete, resulting in very powerful creatures being born.
* There is no information about the human beings of that era, the human beings could only exist in the cracks on various worlds by being slaves of various creatures.
* The ancestral Dragon which keeps helping Long Chen was born and became a terrifying powerhouse during this era.
* The Great Emperor's of Ten Earths like Ghost Emperor were born
* Starry Sky Warriors, known as " The strongest under the stars" were present. They mysteriously disappeared in the Immemorial Age.
* Seven Treasures Colored Glaze Tree also called the tree of wisdom is tree species of Primal Chaos Era. It helps people obtain enlightenment or gain an epiphany.
* The ten Primal Chaos Divine Armament were mostly created in this era. They are the strongest Divine weapons in Nine Heavens and Ten Earth's. A complete Divine Armament can kill even undying, indestructible creatures like Ghost Emperor, Underworld Emperor etc.
* The ancestors of Myriad clans created the Saint King Arena. The champion of this competition would obtain the Saint King Crown, which gathers the destiny of Nine Heavens on the winner. With this blessing, the champion would not face any bottleneck and would be guaranteed to become an Immortal Powerhouse.

Possible contradiction - The Ancestral Dragon tells Long Chen that the fleshly body of human beings in this era was within the top ten among trillions of species. As they relied only on bloodline divine abilities and didn't use any magical technique's.

## Ancient Desolate Era

* Human race was at the bottom of the food chain. Since, they had a weak fleshly body and were smart enough to create many tools, human race was considered as a prized catch by various races.
* Nine Star Lord was born, human race went from being slaves to overlords of immortal world.
* Human race obtained heavenly Dao's blessings and were baptized by divine light, making them create new Cultivation Technique's, Battle Skills and casting items.
* It is rumored that some people opened the Dark door, which allowed beings of the Dark World to invade Nine Heavens & Ten Earths and start the Ancient Desolate Great War.
* Ancient Desolate Great War took place 1 trillion+ years back. This resulted in the fall of human race, Heavenly Dao being incomplete and primal chaos aura flow reducing. All the great inheritances that the Human Beings created during this era were lost after the war. This war is also referred to as ' Primal Chaos Great War'.
* Nine Star Descendants went from being one of the most noble existences in Nine Heavens Ten Earths to one of the most hunted down faction.
* Pill Emperor, Nine Star Lord and other Heavenly God's were betrayed by Great Brahma, resulting in the fall of humans.
* The Three Link Heaven Swallowing Clan who were the overlord of the underworld were betrayed and the serene clan became the new ruler of the underworld.
* Vermillion Bird is said to have gone extinct after the war. Cloud Chasing Heaven Devouring Sparrow most probably betrayed myriad beasts to help human beings, which resulted in then being hunted.
* Ghost Emperor and Underworld Emperor's fleshly body and primordial spirit was destroyed by the Nine Star Lord. Since, they were undying, indestructible creatures, they didn't die.

## Primordial Era

* As the name implies, the Cultivation Technique and Battle Skill, everything is the most primordial, everything is rudimentary. In reality, the Ancient Desolate Great war caused all the great inheritances to be lost.
* After the Ancient Desolate Great war, Heavenly Dao became incomplete and the primal chaos aura flow became less. There by resulting in creatures of every successive era being far weaker than their earlier era counterparts.
* Human race became too dependent on Heavenly Dao, which resulted in human beings being able to create new magical techniques, but having a very weak fleshly body.
* As the Heavenly Dao kept on changing, human beings couldn't create a new body refining system.
* This is the last Era when Heavenly Gods were born.

## Very Ancient Era

* All the branch institutes of Soaring Firmament academy were destroyed.
