According to legend, a hundred years ago, a fox demon bewitched Lingzi and crashed into Broken Moon Mountain, causing the Corpse Puppet King sealed at the foot of the mountain to haunt and wreak havoc on the world. Since then, humans and foxes have stopped interacting. Qi Yuanbao, a young lady from a cultivator family, sneaked out of her home to wander the streets and accidentally entered Broken Moon Mountain, a forbidden place for humans, and met Changqian, a celestial fox who was cultivating there. In this way, a man and a fox met as if destined at Broken Moon Mountain, revealing a love and oath that had been buried for a hundred years.
