After the Marriage Exchange, the Snow Rabbit King Became My Subordinate

In the past life, my sister was bound to the beauty system and married a charming Snow Rabbit King, hoping to dominate the harem with her looks. But who could have imagined that the rabbit tribe has a strong reproductive capacity. After the bridal chamber, she gave birth to litters one after another. Frequent childbirth quickly destroyed her beautiful appearance. The Snow Rabbit King was tired of her marrying someone else, and all the children she gave birth to were thrown into the world by the new queen and turned into spicy rabbit heads. And I was bound to the childbirth system, married to the bloodthirsty and fighting wolf king, and gave birth to the unique Wolverine prince for the wolf clan, firmly sitting on the throne of queen. My sister was jealous that I had a better life than her, so she killed me with a knife in the name of a heart-to-heart talk. When I opened my eyes again, I returned to the day when I was bound to the system, and my sister directly snatched away the childbirth system. "Humph, this time it's my turn to be the noble queen of the wolf tribe." I felt happy, finally I no longer had to be a widow to that stinky wolf.
