The heroine Lingsu was born in a declining beast-controlling family. Because of her unique "empathy" beast-controlling talent, she was regarded as an alien by the family and was used as a pawn for the marriage of powerful people. On her wedding day, Lingsu resolutely ran away from the wedding and broke into the dangerous Ten Thousand Beasts Mountains, where she unexpectedly encountered the legendary cruel and bloodthirsty, half-human, half-beast king of beasts - Cang Ye.
The Beast King, who is feared by everyone in the world, shows dependence and possessiveness thanks to Lingsu's unique soothing ability. Lingsu discovered that this so-called beast king was actually the deposed prince of a neighboring country who was poisoned by a strange poison and whose bloodline ran rampant. She used her beast-control skills to heal his wounds and help him regain his sanity, and he regarded her as his only treasure, taking her back to his "lair" and pampering her in every possible way.
The main plot revolves around the female protagonist "taming" the male protagonist, and using the power of the male protagonist's beast king to subdue the alien beasts in the world. Step by step, she slaps her family and fiancé who despised her in the face, and uncovers the shocking conspiracy that caused the male protagonist's bloodline to go berserk and the decline of her family. Finally, she becomes the co-owner of all beasts, and joins hands with the male protagonist who has restored his identity to rule the world. The highlights are the unconventional way of controlling beasts by "using softness to overcome strength", the extreme contrast of the male protagonist from a ferocious beast to a loyal dog, and the refreshing feeling of counterattack by the female protagonist from an abandoned son to a king.
