Ling Xi, the last "soul-wavers" of the Qingqiu Fox Clan, was born with half a soul-calming bronze bell on the tip of her tail. However, due to the "soul-eating miasma" accidentally placed in the Demon Locking Tower when she was young, the entire clan was eroded by the miasma and turned into a shadow that could only wander in the night fog.
In order to find a way to reverse the situation, Lingxi broke into the human City God's Temple with the remaining half of the fox clan's sacred relic "Moon Soul Scale", and unexpectedly awakened the temple guardian god Shen Yan who had been sleeping for hundreds of years - this god had his bones removed for sealing the great demon. Only the remaining soul was attached to a stone statue with a severed finger in the temple.
