"Food delivery is the surface, survival and exploration are the core" - the modern takeout career logic (order taking/delivery/service/user relationship) is rigorously implanted into the cruel world of immortality, and through the perspective of Lin San, the protagonist with pseudo-spiritual roots at the bottom, it reveals the daily hardships, knowledge monopoly, interpersonal games and secret darkness under the sect system. The tone of the story is "systematic immortality × professional contrast and cuteness × serious survival and wits", emphasizing pragmatic calculations, outsmarting desperate situations and balancing costs.
