Pick up a Novel Heroine and Take Her Home as Your Wife

Help, what should I do if the novel world becomes reality? Each of them is a ruthless person, saying that they want to cross the void and occupy the earth, and first kill the author. The only good thing is that the heroine is not bad looking, worthy of the author's brain that has been lusting after more than ten years. Don't worry, she is a good person and promised to protect the earth. The two of us are worrying about it together, and we don't have a clue yet. How to fix it? ? ?
