Unlike those demon creatures Feng Qing'an met in the forest, who transform into human form using illusion magic, these demon women all possess human bodies. They only retain some racial characteristics that are not human. These characteristics are not in line with their weak demon qi.
From an ordinary perspective, even transformation into a human form is beyond the reach of these low-level creatures, let alone being able to speak. However, right now, within the Ten Thousand Demon Nation, these beings own human bodies that can give birth.
The demons who can transform into humans like this are usually powerful creatures. Of course, beings of special talents, such as the Fox Clan, are capable of transforming into human form despite their weak power. But there should be a limit to how weak one can be.
"Mr. Feng, these are low-quality products. You can look freely but they don't have the right to serve you."
