(This book can also be called "Life Choice Train", the anti-Destiny villain. The book has been restarted, all main lines have been deleted, and the plot has been completely changed. The protagonist has changed gender but remains unchanged and will not marry. Iron-blooded killings and legion training have adopted transgender protagonists. As for the protagonist's ability, it is an ancient artifact, just like the magical girl, but using ancient artifacts to transform, because it is a book about the destiny villain)
50 years ago, our class traveled to this sci-fi post-apocalyptic world, where we were fighting against the insect swarm. There were ten military officers in the empire. In my previous life, I was just a waste. I was framed as a 26-year-old college student with an ordinary appearance in my class. I managed to get into the position of one of the top ten military officers, but I died in the villain's plan. I finally understood that I was just a waste protagonist in the book, and the destiny I had always been proud of was my shackles.
In an accident, I was forced to eat an unknown alien's ovary, but I was reborn 50 years ago and became the queen of that race. In this life, I broke all the fates, and the protagonists here also became women and were recruited into the legion by me. But the truth is far more than that.
No matter when and where, I am the only iron-blooded soldier. Until then, welcome to the train to heaven.
