My App, All Customers Are Ghosts

Starting with a delivery rider account, the underworld is in ruins and must be rebuilt through food delivery! While others deliver food for money, I deliver for merit and to reconstruct the netherworld! First order: deliver longevity noodles to a funeral home → [Ding! Yin-Yang Order +1%, unlock ability 'Evil Retribution'!] Second order: deliver spicy blood curd to a female ghost in a haunted house → [Ding! Netherworld Bestiary +1, unlock building 'Eye of Resentment'!] Third order: deliver sacrificial offerings to a false immortal at a mountain temple → [Ding! Netherworld Territory +5%, unlock artifact 'City God's Broken Seal (Fragment)'!] Fourth order: retrieve a police officer's lingering soul from the police station → [Ding! Netherworld Influence +10%, unlock building 'Reincarnation Inn', obtain employee Qin Weiguo ×1!] From then on, the balance between yin and yang in Binhai City was thrown into chaos. Ghost messenger: 'Report! City God, that century-old ghost on the street has been liberated by a deliveryman!' King Yan: 'Report! Master, the new inn on the Yellow Spring Road is run by a rider!' My name is Lin Tian, an ordinary deliveryman, and my goal is to let the netherworld's signal cover the three realms, so that all gods and ghosts will have to use my app to place orders!
