Rebirth of the Emperor in the Reverse World

I was once the lord of the cultivators in the immortal realm. But I was reborn into a world where the women worked to earn a living, while the men sat around and looked pretty. Even worse, my body looked like a fat slob! I worked hard to get into shape, but I didn't do it for the benefit of you thirsty women!
