The Yin-Sealing Coffin: Seventy-Two Corpse Keys

Chen Ping's family has guarded the funeral home for generations. Since childhood, he has been strictly forbidden from going near the morgue at the western end, a room that has never been opened. On the fifteenth day of the seventh month, when the gates of hell swing wide, his father dies unexpectedly, and a strange noise comes from the forbidden room. By a twist of fate, Chen Ping pushes open the door to the abyss: seventy-two bodies covered in white cloth sit upright in unison and bow to him. An ancient corpse with a bronze key lodged in its throat whispers in his ear, “Young master, the appointed hour has come.” The half of a broken key he always wears fits perfectly with the keys in the corpses' throats, ringing with a soul-searing resonance. A terrifying pact, three hundred years in the making, suddenly weighs on his shoulders. Unidentified corpses keep appearing, strange incidents plague the village, and his father has vanished without a trace. Every clue points to an ancient taboo, long forgotten... He must unravel the mystery of the corpses' words and piece together the complete bronze key before the next “appointed hour” arrives. Otherwise, it won't just be the funeral home's doors that open, but the deadly divide between the worlds of yin and yang! Ancient occult arts, sinister folk customs, corpses whispering, truths buried deep... Amid countless eerie shadows, how will he mend broken hearts and guard the final boundary between yin and yang?
