Supreme Alluring Beast Tamer

She was the leader of the killer organization in the 21st century, but because of revenge, she traveled through time to the body of a good-for-nothing young lady in the vast continent. You said that I don't know how to tame animals, but I have an army of millions of monsters. You said that I don't know how to refine weapons, and even I don't like divine weapons. Do you think I can? You said that I don't know how to make elixirs. I want to refine magical elixirs for beasts to eat as jelly beans. Don't you have any medicinal materials? I have space in my pocket, do you think there will be a shortage? You dare to say that I am a waste. I am a magician and a martial arts master, plus a genius in all departments. If I am a waste, then who are you?
