The Rotary Turtles, like the Xuanming and the Zang Turtles, were all impure descendants of the Xuanwu. After many generations, they were very different from pure-blooded Xuanwu. At the same time, they were able to come up with their own unique abilities and traits.
The Rotary Turtle Tribe submitted to the Heavenly Charms Grand Sage. The current Rotary Turtle Grand Sage was the oldest, and in terms of the cultivation age, few in the Barren Expanses could rival him.
The Rotary Turtle Grand Sage was an Undying Demon Soul Third Level demon, which allowed him a certain amount of respect from the Heavenly Charms Grand Sage. However, he disliked actions and preferred a quiet environment. Hence, he rarely did anything. Yet, both the Barren Expanses and the Divine Lands would not underestimate his existence.
