I said that she would come to my place to watch a movie with her after ten o'clock in the evening. How should she reply when she said it was too late?

Your purpose is to ask her out to the movies and then have in-depth exchanges. It's too late for her to refuse you. Therefore, your reply should think about how to answer it from the perspective of trying to ask her out. Continue to convince her of this reason for resistance. If she doesn't come out at last, you can make an appointment next time.
