The Landlord of the Haunted House: I Rely on Folk Rules to Survive

On the first night of my grandfather's seventh year, I inherited the entire old city's haunted houses. What followed was the [Yin Yang Life Rental System] bound to the soul, and the remaining 7 days of Yang life. Rules at the top: The haunted house must be rented out within 72 hours. Those who break the lease will have their souls annihilated. People in the world fear dangerous houses like tigers, and avoid weird things like Yama. Only Lin Yan did the opposite. Yin evil spirits, crying souls in corridors, living evil spirits without an owner... All desperate situations can be overcome by dismantling the rules, using the rules, and editing the rules. Only then did I know: Keep the balance of yin and yang, and suppress evil in the old city.
