At the junction of yin and yang, the mist-shrouded "residence of the past life" is always lit with warm yellow lights. This is the late-night canteen for psychics and ghosts, and it is also the home where Ruan Tansheng grew up. The half-open birthmark of Manzhushahua on her wrist allowed her to see traces of past lives invisible to ordinary people - until the psychics in the third area disappeared one after another, and the devoured remnant souls floated in the black mist overflowing from the bottom of the well.
Lu Chenzhou from the Underground Special Administration Bureau broke into a back alley with a Beidou pattern silver bracelet. The star-shaped mark under his collarbone echoed Ruan Tansheng's birthmark, which kicked off the Lu family's mysterious retreat thirty years ago. When the ginkgo leaves from the past were stained on the back collar of the man's suit, and when the word "Lu" oozed from the missing ear of the bear, Ruan Tansheng discovered that his father had hidden not only the yellow paper winter clothes for the ghost messengers, but also the bloody past related to the "Yin Yang Division Taboo".
The psychic's soul-suppressing bell screams mournfully at the bottom of the well, and the ability collected by the murderer points directly to the secret of the rebirth pattern. When the brass bell rings again at midnight, the person who opens the carved wooden door may be a seductress or a dangerous man with the smell of cedar. And all the clues point to the old wooden sign that says "Residence in the Past Life" - it is not only a warm place in the world, but also the most dangerous crossroads between the Yin and Yang worlds.
