When social animal Lu Xiaochuan stayed up late to review orders, he was abducted by a nine-headed bird courier and transported to the sci-fi version of the "Book of Mountains and Seas" world, and was forced to become a cross-dimensional express reviewer. From then on, his daily life became to mediate the flooded community of Mermen, design a virtual head display for the headless Xingtian, and help Hanba use air conditioning to control the climate of the parallel world. When Taotie swallowed the entire pizza nebula with his dimensional stomach bag, and when the nine-tailed fox's live broadcast of beauty makeup triggered an interstellar beauty war, Lu Xiaochuan led an AI that could tell cold jokes, Xing Tian with a mechanical arm, and a cry-loving shark to crack the code of ancient civilizations while delivering food, and also to fight against a mysterious organization that attempted to destroy the universe with negative reviews. This is a fantasy comedy that transforms the exotic beasts from "The Classic of Mountains and Seas" into couriers and lets social animals deliver food in the interstellar world. When the bizarre order of "delivering magnets to black holes" meets the ultimate mission of "saving the universe with the energy of positive reviews", see how the social animals use their complaints and imagination to carve out a counterattack for express delivery in a dimension where gods fight!
