Su Yuan, a modern social animal, entered the mythical world by mistake. Before he could appreciate the flowers and plants, he was involved in the "apocalyptic crisis" between gods and monsters. He teams up with the cold-tongued mythical beast Qingluan, the former savior Zhao Qi, and the ill-fated ruby demon princess to break through. The story is compact and humorous. The protagonist is clumsy and tongue-tied, but due to a mistake, he becomes the only "key variable" that can save the Three Realms. Mythical heroes, monsters, Nuwa, and Xuanyuan all appear on stage, taking turns to stage hilarious plots and passionate twists. The three-volume story progresses layer by layer, with both the warmth of growth and the depth of the mythological structure, and finally ends successfully with laughter and tears.
