There is a "ghost postman" in the world who specializes in delivering "ancient tomb debt deed express" to living people. The resentment of the dead in the tomb condenses into a "debt deed", which if not taken out and delivered, will backfire on the world; and the "debt deed" itself carries a soul-eating curse, and the recipient will be gradually swallowed up by the resentment. If it were you, how would you solve the mystery of this cycle of life and death?
