Lich Hand to Destroy Flower (2020)

"Jiang Fei," also known as Red Concubine, is a tale from Pu Songling's "Strange Stories from a Chinese Studio." A young woman has been murdered by a vampire, and Constable Song Yichen investigates the crime scene, discovering a flower mark on the victim's forehead. When Song Yichen is attacked by a tree spirit, Jiang Fei, a flower fairy working on Earth, rescues him and takes him to the Three Heavens. Song Yichen finds an identical flower mark on Aunt Jiang Fei and suspects her of being the killer. Lei Ning'er, leader of the Demon Hunters Clan, helps Song Yichen investigate. She is secretly a tree spirit seeking passage to the Three Worlds to avenge her aunt's death. Lei Ning'er repeatedly frames Concubine Jiang, even killing Feng Yan, who is in love with Song Yichen, to make it appear as though Jiang Fei is guilty.
