After Chen Mo lost his job as a delivery boy, his phone automatically installed an APP that could not be uninstalled - "Abyss Express". The system is forcibly bound, and the delivery scope covers the interface between reality and the indescribable: delivering sedatives to nightmares, delivering contracts for ancient beings, and delivering "things that should not exist" to containment sites. The reward is lifespan, non-common knowledge skills, and a gradually alienated body. Refuse delivery? The system penalty is "cognitive breakdown" - you start to understand things you were never meant to understand. Chen Mo's daily creed: "Don't wonder what's in the package, don't ask who the recipient is, don't think about why you sent it. Just complete the delivery and come back alive." Until he received a special order: to send a "living star seed" to the mouth of the "Sleeping God" three hundred meters underground in the city - and the order notes read: "If this order fails, the real latitude will collapse."
