“Ding! You have a new underworld delivery order.” A shabby phone flashed a blood-red notification. Lin Xuan, a living food-delivery rider, was 22 and had borrowed against his lifespan. He had just thirty days left to live. To extend his life, he had to rise to “Ghost King of Ten Thousand Deliveries” on the Underworld Delivery app and amass one hundred thousand merit points. In the night wind, he picked up his delivery box. A soul-suppressing talisman was stuck to its lid, and in his pocket he carried half a piece of lightning-struck wood passed down from his ancestral master. His goal: deliver ten thousand orders within thirty days and make it back alive.
