You Say I Am Cannon Fodder and I Am Cannon Fodder?

When Si Ruoyi woke up, he was reborn, and returned to the time when he was eighteen years old, when the Si family had not been wronged and all their relatives and friends were present. And this time she could also hear a voice. Her future was actually about being sent to the countryside for seducing a man and eventually dying of a tragic illness. The person's original voice was "a cannon fodder heroine who became a tool in order to advance the relationship between the male and female protagonists." Si Ruoyi could be reborn, so of course she believed what this man said was true, so she decided not only to change the fate of the Si family, but also to rewrite the outcome of the future. But I didn't expect that she was not the only one who was also reborn! What kind of rebirth banquet is this?
