Am I Not a Primordial Saintly Demon Cultivator?

Xu Yun transmigrates to a world of immortal cultivation and awakens the First-Born System. Every time he does something utterly outrageous, he receives a reward and grows stronger. He wants to be a good person, but with the Great Dao right in front of him, he has no choice but to give in. Yet things often take unexpected turns. “Friend, your soul is incomplete from birth. Let me cleanse it in my Banner of Ten Thousand Spirits, and I’ll return it to you whole.” “Thank you, senior! You destroyed the evil remnant soul inside me. You truly are a benevolent soul!” “Fellow cultivator, I’ve always been kindhearted. I can’t bear to see you suffer. How about I send you into reincarnation with one stroke of my sword, then bring you back in your next life?” “Thank you, fellow cultivator! You helped break the demon’s seal inside me and gave me a new life. I’ll never forget your great kindness!” “Fellow cultivator, the treasure in your hand is too sinister. Let me hold on to it for you while I purge the evil thing inside.” “Your insight is truly remarkable, fellow Daoist, and your righteousness knows no bounds! At a glance, you saw the powerful demonic cultivator lurking within this treasure. You are truly the foremost leader of the righteous path!” After Xu Yun does one outrageous thing after another, he looks back on the path he’s traveled. Everyone he’s tricked is sincerely grateful to him, and he can’t help feeling that something isn’t quite right. Strange. Aren’t I a first-born demonic cultivator? Why are these people so friendly to me, and why do they even revere me as the Lord of Heaven and Earth?
