I Swapped My Husband's Baby for My Mafia Rival's

After the great war between the three clans of Human, Dragon, and Wolf, the Dragon Clan and Wolf Clan were cursed. Pure-blooded descendants of both clans could not inherit full power. To pass down the power of their bloodline, Kings of each generation of Dragon Clan and Wolf Clan would need to be with a Human woman who possessed Blessings. Whoever gave birth to a child of mixed heritage first would have their clan rule the three clans for a hundred years. In my past life, I married the King of Silver Wolves, Silas Hector, who was known to be a gentleman. One year after my marriage, I gave birth to a child who was half Wolf. He inherited full power from his bloodline, and Silas became the ruler of the three clans. The Wolves ruled the world for a hundred years. My sister, Lucia, became enamored by the magnificent Silver Dragon. She married the King of Silver Dragons, but the Dragons were arrogant and unpredictable. In a moment of mad rage, her husband injured her womb and caused her to miscarry. Lucia became barren after that. Lucia went crazy with jealousy for me, and she stabbed me to death during a family reunion. When I opened my eyes next, I had returned to the eve of the wedding organized by the three clans. Lucia was quick to enter the room of Silver Wolf King, Silas, and sleep with him. She was reborn too. However, she had no idea that Silas was a cold-blooded wolf who enjoyed torturing weak Humans.
