I Dress up as the Cannon Fodder Ex-Husband of the Hero of the Starting Point

I traveled through time and became the cannon fodder ex-husband of the male protagonist of a starting point novel. The male protagonist went to extreme lengths for his own plan and was forced to marry me. My mother and I sneered at and bullied the male protagonist every day, and even made him wash my clothes, cook, and carry water for my feet. The male protagonist endured the humiliation, swallowed his anger, and finally succeeded in counterattacking. Then I was cannon fodder. … I decided to change the previous ending. The reason why the male protagonist can make me cannon fodder must be because the male protagonist successfully counterattacked and became the richest man in the world. As long as I defeat the male protagonist and become the richest man in the world first, the male protagonist can no longer use me as cannon fodder. … Later, my plan succeeded. It's just not what I thought. Now I really want the ending to be similar to the one in the book. She works diligently and diligently every day and is bullied by the male protagonist. Purpose: To be a useful person to the country and society
