I Became the Cannon Fodder Best Friend of the Heroine of the Ancient Sadistic Novel

It's okay, but why can't I post a short review? And isn't this written yet? Why is there no follow-up? The heroine's name is Tianxiu, and the original heroine of the sadistic novel called her Xiu'er. The original sadistic novel is very classic, why should the male protagonist let other people be buried with him, and let the female protagonist of the sadistic novel give birth to hundreds of children? There was a blood feud between the male and female protagonists of the original sadistic novel, so Tianxiu tried hard to ask the female protagonist of the sadistic novel to use her love brain, but I didn't see anything useful. In the end, the female protagonist of the sadistic novel still had a soldier-like appearance. Anyway, the ending is too hasty... It turns out there is a follow-up... The ending is very satisfying. The heroine of the original sadistic novel kills the hero and becomes the empress. It's so cool!
