**Synopsis of Seven Days in the Haunted Ruins**
Chen Xuan, an undertaker at a funeral home, is working the night shift when he mistakenly sells “three long, two short incense sticks” to a corpse in red. From that moment on, he is plunged into a sinister world between yin and yang: the Yin Ruins. This death-filled city resets every seven days. Mythical beasts from the Classic of Mountains and Seas roam its cyberpunk streets, the vengeful spirits of Ming dynasty alchemists manipulate quantum laboratories, and folk taboos become rules that devour the living. Coffins are hidden among convenience-store shelves, the last subway train becomes a funeral procession, and any living person who locks eyes with a ghost for three seconds becomes a “ticket.”
Armed with a Judge’s Brush that can rewrite the Book of Life and Death, Chen Xuan forms a deadly alliance with Lin Xi, a folklorist versed in the Lu Ban Book, and Zhang Jiuzhi, a knife seller who trades on credit and has lost a finger. They discover that every haunted domain hides a bloody sacrifice spanning six centuries: corpses from seven lifetimes of reincarnation lie frozen in a convenience-store freezer, a bronze compass burns memories as fuel, and the AI System “Nuwa” is actually the cybernetic remnant of a Ming dynasty alchemist.
When a countdown tattoo appears on Chen Xuan’s arm, he finally realizes that this so-called “seven-day rebirth” is nothing but a ruse for the Lord of the Ruins to harvest souls. And deep within the Yin Ruins’ quantum celestial palace, his left eye, gouged out three hundred years ago, is gazing at every dying person in the present world…
