On the third day the clan's special egg hatches — but instead of a powerful ninth‑rank member, a man who just transmigrated wakes up transformed into a small koi in the lake. Seven mermaid daughters inspect him, mock his lack of rank, and argue about eating him for spiritual power. He begs for mercy, claiming to be a lucky mascot. Linda insists he could bring good fortune and urges sparing him, while others dismiss luck in favor of strength. As the sisters bicker, the Devouring Evolution System activates, abruptly raising the stakes and leaving his fate undecided.
