I recommend Bringing the System to the Beast World. The protagonist of this novel, Chen Wanwan, jumped off a building and transmigrated to the ancient Beast World. She was surrounded by beastmen. She used her own advantages to become a powerful existence. She carried a portable space and a big steel knife. She challenged the strong people of the tribe, led the beastmen, and lived an extraordinary life in another world. I hope you like this fairy's recommendation. Muah ~😗
