In the apocalyptic wasteland sea, defective white mermaid Xue Ji was utilized by her adoptive father Shen Du. While Atlantis new king Lan Xi was heavily wounded, she stole his SSS-grade genes and conceived his three pure-blood embryos. In her past life, after the embryos matured, Shen Du sliced open her abdomen alive to harvest the eggs, throwing her into a radiation trench to feed mutant sea beasts. Reborn, Xue Ji escaped to Atlantis with the embryos in her belly, publicly shouting out 'I carry your pups' at Lan Xi's enthronement ceremony. At first Lan Xi did not believe it, but his out-of-control body and the bond of blood forced him to face this 'defective product'. The two gradually drew closer through life-and-death struggles, and Xue Ji even discovered the mystery of her own background in the secret realm.
