Old Ancestor Xue Hu wanted to kill Bi Chen Tian, but at this moment, the dog tail life extending ferret, Mao Li Qiu, appeared.

"Why is this ferret here? Doesn't it stay inside its cave all the time?" Old Ancestor Xue Hu was surprised.

This ferret had a huge origin, it was Giant Sun Immortal Venerable's steed. Giant Sun Immortal Venerable had subdued it in his later years, his motive was clearly to find a lifespan extension method.

The dog tail life extending ferret's dao marks were very numerous and mystical.

As it grew older, the dog tail would shrink as its lifespan decreased. When its lifespan nears its end, the tail would vanish.

Thus, whenever it sensed that its life was ending, it would devour an immemorial desolate beast dog. After consuming it, the dog tail life extending ferret would gain the lifespan of this immemorial desolate beast dog, its tail would grow out and it would continue living.
