Yang Peng's alien series original science fiction works. The book continues Yang Peng's consistent style of creation—incredible imagination, extraordinary exaggeration, unrepeatable comedy, bizarre plots, sci-fi elements, relaxing, humorous, and thrilling fun. At the same time, courage, integrity, kindness, unity, patriotism, and environmental protection are integrated into the delightful storytelling. The theme is positive, setting a good example for the children.
