Magic Pet Emperor Phoenix

I just had a good sleep on my birthday, but when I woke up, I was soaked in a coffin and almost drowned! Let's just accept a world without humans, but what's the situation with these monsters lining up! There's endless food to eat, endless clothes to wear, and endless money to spend, but can someone help me when I'm in trouble? After finally coming out of the human world, who is that woman who looks exactly like me but is stronger than me? If you want to compete with yourself for a man, you really need the strength of a man! She is the weakest heroine in history, but all the demons in the palace let her bully her! She is the weakest heroine in history, yet everyone in the human world respects her like a god! She is the weakest heroine in history, but the Supreme Demon King dotes on her in everything she does in heaven and earth! So this world is indeed a fantasy!
