The old era vanished into thin air, leaving behind countless strange and mysterious buried deep underground. But thousands of years later, the excavation of the relics of the old era by the new era has gradually awakened those unfortunate things...... An unknown side of the world gradually emerges - the flesh and blood remains that pollute reality, dead babies soaked in bottles, puppet dolls sewn from human skin...... Calamity, misfortune, death and fear gradually spread in the corners of the city. Su Bai crossed over and accidentally inherited the ruins of the underworld left over from the old era, and became the only remaining Yin official who started from scratch. The reconstruction of the yin and yang order in this world will start with a small living yin official!
