On the Majestic Development of the Young Female Devil

I, Italis, am eight years old, a young female, and a professional demon king. I am 1.2 Meters tall. No one in the world except the brave can be my opponent. Only three of the four kings under me can be my opponent. The twelve demon generals cannot last one round in my hands... Theoretically, no one dares to have an objection to me. But the problem now is that because of my young appearance, my subordinates treat me like a child and do not allow me to participate in any discussions or projects. The regent also treats me with toys, games and snacks. It's not a good idea to attack your own people randomly. How can you make yourself look more dignified? Waiting online, urgent. And what is meat armor? (Single + light hundred, there are people who like the protagonist but no results)
