I Deliver Packages to the Ancients

Blurb 1: Send a world map to Qin Shi Huang, who unified the land. Send Jing Ke a high-carbon steel dagger. Send Huo Qubing, who subdued the Xiongnu, capsules of penicillin. Send Zhou Yu, who loved listening to music, a vinyl record. Send Zu Ti, who rose at the sound of a rooster to train, an alarm clock... Her job at a time-delivery company is to transmigrate through time and fulfill the fantasies people in the year 2821 have about the ancients. Using technology to crush ancient civilizations and feel superior is dull and empty. It is probably one of the few pleasures left to modern people. But she has to experience life as the ancients lived it, and in that world she truly finds something precious: simple family affection, friendship, and peaceful days. Blurb 2: His name now is Zhao Xun. He has had many, many names, but among those countless names, he remembers that his first was Ying Zheng, a member of the Zhao clan. No one can escape the natural cycle of birth, aging, sickness, and death. But there is another kind of immortality. A sorcerer told him that if he took this elixir of immortality, when his body was dying, he could preserve his memories and enter a new body, beginning another life in an endless cycle of reincarnation. Then he discovered that there seemed to be someone else who could also "live forever." He would encounter her once every few lifetimes. He founded a time-delivery company and recruited its one and only time courier. He needed this fascinating person to travel through time and keep him company through his three thousand years of loneliness. Theme: A story about ideals of all kinds
