My enemies became my companions

Women who were deadly enemies of the protagonist in his past life now become his concubines. Among them are an Empress Dowager who ruled in the emperor’s place, the Demonic Sect’s pure and flawless Saintess, a one-armed sword master ranked ninth in the world, an emotionless Celestial Maiden of Mount Taihua, and the chivalrous, tender-hearted Sword Master of the Spring and Autumn Period. Danger surrounds him as these former foes submit to him in shame and humiliation.
