During the Qianlong period, scholar Liu Wenyuan went to Qingzhou to visit relatives and stayed at Ciyun Nunnery to take shelter from the rain. The ghost in white clothes by the well gave him a bronze mirror, with the words engraved on the back of the mirror: "The past is like smoke, and the reflection becomes evil."
Imprisoned in the mirror is the remnant soul of a spirit fox that has been practicing for three hundred years. Thirty years ago, Bai Wanniang, the daughter of Jinan Tongmen, died suddenly while holding this mirror on her wedding night. The groom went crazy on the spot. In pursuit of the truth, Liu Wenyuan discovered that the resentful ghost in red and the crazy groom in the inn were all chanting the same curse.
When the truth emerged, Liu Wenyuan discovered that all the clues pointed to an old friend he trusted most. And what is reflected in that mirror, is it the substitute's injustice or his own ending?
