In the ancient Yao Kingdom, the mist-shrouded Qinglan Mountain, and the mysterious deep sea Guixu, three unrelated worlds have their fates intertwined due to a catastrophe. The "shadow" that had been sleeping for three thousand years awakened, the earth trembled, and the seal collapsed. Seven descendants of the secret keeper from the land, the world of immortality, and the abyss were forced to assemble - the emperor who pretended to be dead, the escaped immortal siblings, the double-faced queen of the deep sea, the surviving mute girl and the prince. They must build trust amidst suspicion and betrayal, and find the truth among the broken seals. This is an epic struggle spanning land, sea and air, and a legend about protection, sacrifice and bondage. When the destinies of the three worlds are reconnected and the ancient covenant rings again, the last secret keepers will use their lives and blood to fight for a dawn for this world.
