My Righteous Sect, You Want Me to Accept Demon Cultivator Disciples?

Su Zhe traveled to a fantasy world. And he became the leader of the Lingjian Sect, a righteous sect certified by the Immortal Alliance and a fourth-rate small sect. And successfully awakened the "Magic System"! "Well, although it is a small fourth-rate sect, it is still a righteous sect." "Wait, what is the magic system?" "What does it mean that only recruiting disciples with demonic cultivation potential can get rewards?" "I am an upright sect, and you want me to recruit demon cultivator disciples??" But there is no way, the system gives too much. … The first disciple Su Zhe accepted was the genius who had his supreme talent dug out. Disciple: "Master, does this "Blood-Burning Kung Fu" sound so much like a demonic technique?" Su Zhe: "What magic technique, nonsense! Haven't you heard of blood boiling? Practicing this technique can make your blood boil and your energy full!" Disciple: "That's it!" … Disciple: "Master, this "Blood Evil Technique" requires drinking blood to become stronger. Isn't this a demonic technique?" Su Zhe: "You're talking nonsense here again! What's wrong with sucking blood? Is it pig blood or duck blood that tastes bad?" Disciple: "Oh! It turns out that blood is not just human blood. Disciple understands!" Su Zhe let out a long sigh: "These are all righteous exercises from the Eight Sutras. Don't think wildly. Practicing hard is the righteous way." … Many years later. Everyone was dumbfounded when they looked at the disciples of Lingjian Sect, who were all upright but full of black energy. "No, the demonic energy has leaked out, and you still say that you are a righteous sect?" …
