Reincarnated Demon King: Stop the War Train

I've had enough. It's been three days since I was reincarnated into the body of this demon king named Azkel. Everyone in this group of demons was scared to death when they saw me. No matter who they were, they would tremble, and no one dared to look at me. They all agree that I will go on a killing spree if I don't get what I want, but I don't kill people casually. I've never even killed a chicken in my life. Don't look at me like that! I don't even dare to say it. Who can I tell it to? I always felt that once I was exposed, I would be killed. The atmosphere in this court was so suffocating, it was like a prison of mental torture. Who can I chat with? Oh, the chamberlain named Mila seems to be very kind to her, just her, there is no other choice! I hope she never tells anyone. Please, just have a normal chat with me. Please, my spirit is about to collapse...
