[Comprehensive British and American] Technology Killer

Before picking up the man with the metal arm, Elsa lives like a primitive human being; But after the guy who was assigned to his territory disappeared inexplicably, Elsa decided to muster up the courage to go outside and find him. So Elsa, who came to modern society, became a walking murder weapon—— "Why can't I post on Twitter?" "Why can't I get through on the phone?" "Is the weapon broken?" "WIFI? If the WIFI is broken, I'll wipe it!" "J? J? Are you blocking my butler again? Elsa, please restrain yourself!" The male protagonist drags his mechanical arm that cannot move at all, haha. The cp's mouth is clear, the heroine's abilities are weird, and the author's imagination is sick. There are many private settings, please correct me if there are any mistakes. Welcome to communicate, I will save that male god! Pay attention to details and make logic as reasonable as possible. I really don't know enough about life abroad, so some details are vague. Warning: The triggering incident will be cleared up, some people will protect it, and the twins will change the settings... Happy reunion settings Intention:
