Reborn from a tragic death in the Soul‑Devouring Maelstrom, pure‑blood golden‑scale siren Seraphina swears vengeance against her traitorous husband Tristan and her fake sister Vanessa. When Tristan, also reborn, publicly breaks their engagement and slanders her at her coming‑of‑age ceremony, Seraphina takes a desperate risk. She travels deep into the abyss to seek offspring from Caspian, the so‑called brutal low‑rank Shadow Siren, who is actually the ancient Abyss Sea God and Ancestor of All Oceans. At the grand sacred ceremony, Vanessa uses dark sorcery to produce a counterfeit golden pearl, while Seraphina gives birth to nine seemingly lifeless black pearls and faces public trial and manhunt. At her most desperate, Caspian arrives in overwhelming power. He exposes Vanessa's true identity as a deep‑sea parasitic eel and defeats Tristan. After absorbing the sea god's divine blood, the nine black pearls hatch into nine god‑level sea beasts mastering ocean laws. Cleared of all false charges, Seraphina punishes the villains and ascends alongside Caspian. Together with their nine divine children, they become the supreme rulers over all seas.
