A detective from the Republic of China was hired to investigate the mysterious deaths of many wealthy people in Shanghai. The deceased's faces were peaceful but their internal organs were missing. The clue points to a peep show shop, where the owner claims to be able to take "soul shadows" of people - a mirror personality opposite to himself will appear in the photo. When the detective conducted an in-depth investigation, he found that he had also been filmed, and his exact "doppelgänger" appeared in the mirror. It turns out that the shop owner is the reincarnation of a magician from the Qin Dynasty. He used the fragments of "Stories of Strange Tales" unearthed in Fangmatan to split the human soul into a "yang body" and a "yin body", and used the yin body to devour the yang body to survive. In the end, the detective cooperated with his doppelganger and used the principle of mirror reflection to bite him back.
