I'm from the Righteous Sect, and You Want Me to Take on Demonic Disciples?

Su Zhe transmigrated to a fantasy world. He also became the sect master of the Spirit Sword Sect, a fourth-rate minor sect recognized by the Immortal Alliance as an orthodox sect. And he awakened the “Demonic Path System”! “Sure, this is a fourth-rate minor sect, but at least it's an orthodox sect.” “Wait, what do you mean, a Demonic Path System?” “What do you mean, I only get rewards for recruiting disciples with the potential to cultivate the demonic path?” “I lead a respectable orthodox sect! You're telling me to recruit demonic cultivators??” But there was no helping it. The System's rewards were just too good. The first disciple Su Zhe recruited was a prodigy whose Supreme Dao Bone had been dug out. Disciple: “Master, why does this Blood-Burning Art sound so much like a demonic cultivation technique?” Su Zhe: “What demonic technique? Don't talk nonsense! Haven't you heard of getting fired up? Cultivating this technique will get your blood pumping and leave you full of energy!” Disciple: “I see!” Disciple: “Master, this Blood Fiend Art says you have to drink blood to grow stronger. How is that not a demonic cultivation technique?” Su Zhe: “There you go talking nonsense again! What's wrong with drinking blood? Is pig's blood not tasty? What about duck's blood?” Disciple: “Oh! So blood doesn't just mean human blood. I understand, Master!” Su Zhe sighed deeply. “These are perfectly respectable orthodox cultivation techniques. Don't let your imaginations run wild. Focus on your cultivation. That's the true path.” Many years later. Everyone stared in shock at the Spirit Sword Sect's disciples, each one righteous in bearing yet wreathed in black energy. “Come on, the demonic energy is practically spilling out of you. How can you still claim to be an orthodox sect?”
