Basically, Xiao Xun’er is the main love interest of the protagonist, Xiao Yan, in Battle Through the Heavens. She belongs to one of the ancient and main powerhouses, the Gu Clan. Her Gu Clan origin is revealed much later in the story. We also learn that she was sent to the Xiao Clan to obtain the ancient key, which is part of a larger key needed to open an ancient Dao Di’s tomb. Anyone who opens that tomb will be able to inherit Dao Di’s ancestry, thus becoming a Dai Di.

My Thoughts on Xiao Xun’er – Battle Throught the Heavens
The character of Xiao Yan’s sweetheart, and later wife deserves a praise far more than given in the donghua. She is one of the main reason’s the Xiao Yan rose from a helpless teenager to Flame Emperor. She helped him in shadows, and in person when he had no one else to turn to.
Her Dao Di bloodline is a catalist to her rapid cultivation. And unlike most characters she inherited most of her powers, and abilities. Her attachment to the protagonist is no secret to anyone in the continent. Presently, in the donghua, she is staying at Gu Clan, while Xian Yan is heading to his home town to help Yan Alliance who are in a desprate struggle against Hun clan and others. A truly exciting battle, and awesome reunions are going to happen. Thoughts?
