I, the Young Master of the Demon Sect, Have All the Fairies Become My Power Training?

[The villain is cool + the young master of the demon sect + the system is wrongly tied + the saint undercover + the fairy harem + the female lead training + the more you kill, the stronger you become + the misunderstanding of Dihua] Bad news: He traveled through time and became the young master of the Demon Sect who was full of evil and wanted to be hacked to death by the whole world! Good news: there's a cheat! Even worse news: I'm not the one bound by the golden finger! [Host: Shen Qingli (the Holy Maiden of Taichu)] [Task: Within seven days, practice the "Phaseless Demon Sutra" to the first level] [Task reward: Innocent Sword Bone, three hundred years of cultivation] [Penalty for failure: obliterate the host] Xiao Wujin looked at the panel in front of him and fell into deep thought. Golden Finger is very strong, very good, and perfect. The only problem is that my name is not Shen Qingli! How could a righteous saint who came undercover to assassinate me have a system? Etc! It turns out that as long as she completes the task, all the rewards will be sent to my body? Saint, stop pretending to be dead and get up and work overtime! Xiao Wujin: "Take it and practice this "Phaseless Demon Sutra"." Shen Qingli gritted her teeth: "Devil, I am a righteous fairy. I would rather die than practice demonic skills!" Xiao Wujin: "If you don't finish practicing for seven days, you won't be allowed to eat, and you will be dragged out to feed the devil dog!" Shen Qingli (bearing the humiliation): "Okay... I'll practice! When I find out the flaw, I will kill you with one sword!" Mission completed! Three hundred years of cultivation have been released into Xiao Wujin's body! After tasting the sweetness, Xiao Wujin completely ceased to be a human being. [Practice Mission: Kill the Ancient Ten Thousand Souls Blood Demon] [Task reward: Perfect Supreme Sword Heart, Ten Thousand Years of Cultivation] Xiao Wujin: "Go, Saint, chop up the ancient blood demon in front of you!" Shen Qingli's mentality collapsed: "That's your Demon Sect ancestor! You want me to chop him up?!" Xiao Wujin: I'll chop it up if I ask you to!
