You didn't mention the Succubus' features. We don't know what color her hair is, what color her eyes are, how tall she is. The same goes for mc. Please write in more detail. Don't just say he is beautiful or handsome[img=recommend]
Succubus Army? This is similar to another novel where the protagonist own a Succubus Army as well and he was transmigrated too.....I think the title is Lord of the People...
