There was a question: How many clans were there within the Black Mist Zone?
There was only one answer: There were too many to count.
Then the next question: Could anyone remember the appearance of all the different clans?
The answer was also obvious: Of course not.
The history of the Black Mist Zone was too ancient, and over the long years, countless tribes became the chosen ones to undergo tribulation, and numerous races integrated into the Black Mist Zone.
What was worth mentioning was that some races had unique forms that prevented them from marrying other races. However, most races did not have reproductive isolation between them. This led to a much greater population of mixed-blood intelligent beings than pure-blood ones!
In short, the diversity of intelligent species in the Black Mist Zone was so vast that even scholars specializing in this field could not comprehend it in a short time.
