Bang Ding Duotai Xitong, Wo Nanie Shou Shi Xiuluo Chang

To fulfill her deepest wish, Su Yan enters the realm of beasts, only to wake up as a tiny white mouse, bound to a multi-pregnancy system. To level up, she must tame one beastman after another: a battle-scarred leopard warrior, a fierce rabbit beast, and more. Each is terrifyingly strong in beast form and impossibly handsome as a man, and each one hits her right in her soft spots. With a swelling harem and a system that keeps pushing her deeper into this wild love battlefield, Su Yan’s poor heart is about to explode. But she just might turn the tables, seize control of this savage game, and tame the entire realm of beasts for herself. (Source: Webnovel)
