Exploring my own vision of Xianxia Smut with the debut novel, "Immortal Only Accepts Female Disciples"
My pet peeves:
1) I don't think harems should grow too large, too fast. At that point, individuality is lost in the avalanche of free vagina, resulting in flat, emotionless, and boring female characters. New harem members also should not supersede the previous harem members and make them useless.
2) Dialogue that goes no where and only serves to pad word count.
