Pick a Mountain King as Your Wife

Legend has it that on a distant continent, only beasts live here. There is a mountain on the continent that has been shrouded in clouds and mist all year round. There is a "mountain king" in the mountain. No one knows where this king comes from. They only know that he can speak animal language, command the beasts, call him the king, and protect the peace of the continent. I don't know when the beasts discovered that their king's aura could no longer be found on this continent. At the same time, the humans born on this continent over time have become extraordinarily powerful. In order to pursue power, they began to capture a large number of spiritual beasts. Most of the spiritual beasts with low cultivation were unfortunately caught, while the spiritual beasts with intelligence were hiding in the dangerous mountains, waiting for the return of my king. So the story starts from this continent...
