The film was inspired by the Chinese folktale Legend of the White Snake and was released in China on January 11, 2019.

They find a jade hair pin which brings back some memories when it is then revealed, that the hairpin too is magical.

Her elder sister Verta argues otherwise and says that she will find and return her, whilst also engaging in an insurance policy- if she is not back with Blanca in three days, then the Death Scales embedded in her will explode and kill her.

Later they eventually get to Special Jade Workshop, owned by a fox-demon who makes all types of magical weaponry.

Workshop mistress does turn him into a demon with a dog tail, but warns that Xuan will be of the weakest kind and will never grow stronger, and that humans will likely kill him on sight.

Out of desperation, Blanca uses the magic wand again, absorbing the daoist's powers and turning into her giant demon form.

The Dark General arrives, eager to conquer the snakes, but hearing of Blanca's acquired power, allows Xuan one final attempt to talk to her.

Xuan confesses his love to Blanca and offers her to escape to the lands beyond, living together and without any more humans or wars; she almost subsides, but in the last moment the Dark General's magical trap binds them both to the ground.

Dark General intends to harvest their essence, as he has found the secret of immortality: consuming spirits of demons, making them unable to reincarnate, but prolonging his life and fueling his magic.

Verta manages to trick the General into absorbing her soul first, which also transfers the cursed Death Scales onto him.

With her strength almost gone and no way out of the trap, Blanca uses the jade wand one last time, saving Xuan's spirit and memories in it and escaping with Verta.

In the mid-credit scene, the fox-demon from the shop arrives to the same port delivering a box to a mysterious river monster under the bridge.
