I'm in the Righteous Immortal Sect, and You Want Me to Cultivate Demons?

A hundred years ago there was a battle between good and evil. Xuan Tianqing, who was originally a cultivation prodigy, self-destructed his cultivation and fought to the death with the demon elders. However, his cultivation level fell to the acquired realm and his cultivation foundation was completely destroyed. Only Xuan Tianqing himself knows. The demon elder forced him to hit him three times with all his strength before he died, leaving a piece of demonic power in his body at the cost of his own death. If Xuan Tianqing wants to continue practicing and break through the realm, it is not impossible. As long as he practices the dual magic skills left in his body by the demon clan elders. Xuan Tianqing was originally an upright monk, and the rules of the Jade Girl Sect were deeply rooted in his mind. Until the end of the day after tomorrow has arrived. He died of old age alone on Xiao Qingfeng without resorting to practicing magic skills to break through the realm. Xuan Tianqing, who came through the soul, looked at the nine main peaks and the ninety-nine sub-peaks of the Jade Girl Sect, and thought that she had fallen into the land of gentleness. Double cultivation? Magic power? So what? Little did I know. In the entire Jade Girl Sect, all women practice the Jade Girl Heart Sutra and must never lose their virginity... Xuan Tianqing, where should we go?
