The Longevity Express

On the day deliveryman Chen Ping'an delivered his 10,000th package, he received a parcel with “Heaven's Way” listed as the sender. A System activated in his mind: [Immortality System bound. Host will gain eternal life. Mission: Deliver a package to one person who is about to die each week. Each successful delivery adds ten years to your life. Lose one package, and thirty years will be deducted.] He dutifully delivered packages for ten years, almost earning enough for a vial of potion that would end his contract and let him return to an ordinary life. The recipient of his final package was his seventeen-year-old daughter.
