Shen Mei transmigrates into an interstellar beast-world novel starring a powerhouse female lead, becoming a cannon-fodder supporting female character contrasted with the heroine Ning Xue. In the book, she boasts a prominent family background, doting father and brothers, and astonishing talent; apart from a somewhat ordinary appearance, she has advantages everywhere. Just as the mainframe assigns her a beast-husband and her marriage certificate is still warm, the marine era arrives. Land beast-men, once sought after and chased after by all, are reduced to useless beasts overnight, while aquatic beast-men, once reviled and reeking of fishy odors, become sought-after survival guarantees. Shen Mei loses her spiritual power, her land beast-husband cannot enter the sea to hunt and cannot support her. Shen Mei harshly curses the original owner as perverted, but upon opening her eyes, she has transmigrated to the scene where beast-husbands are being sold.
