Black Moonlight Who Was Reborn as Both Good and Evil

Qu Jingyuan was the sworn brother of the Demon Lord, a dignified little Demon Lord, but he died miserably. He died on the day of his sworn brother's wedding. The demon world was captured by the Immortal Sect, and the entire clan was massacred. The culprit is Xie Fu, the Xuanmen immortal master whom the sworn brother wants to marry. A few months ago, Xie Fu was captured, his golden elixir was melted, his cultivation was completely destroyed, he was imprisoned in the demon world, and was tortured day and night. Qu Jingyuan took pity on him and secretly sent him medicine, food and drinks behind his adopted brother's back, and the two established a friendship. Who would have thought that he would be used by Xie Fu to dig out the heart-protecting scales. On the day when the clan was exterminated, Qu Jingyuan knew that he was seriously injured and could not save himself, so he simply jumped into the Bone Transformation Pond with his adopted brother's body in his arms. But not dead! Reborn! Back to twenty years ago! He even became Xie Fu's little apprentice! Every day, I face the brother-killer/family-killing enemy/the heartless man/sister-in-law, and I still have to kneel down to reply! After assassinating the "Master" overtly and secretly no less than a hundred times, but to no avail, Qu Jingyuan decisively escaped from the Immortal Sect and planned to seek refuge with the Demon Lord. He tried every possible means to persuade the Demon Lord to destroy the Immortal Sect and kill that hypocrite. What a villain! Unexpectedly, at that time, the Demon Lord was lying drunk on the beauty's lap, and he ordered his subordinates: Pull this ugly thing down, chop it into pieces, and feed it to the dogs! Qu Jingyuan:...... Wait, his mature and steady, cool and noble, dedicated and affectionate, and extremely gentle and powerful good sworn brother was acting like this when he was young? In order to prevent the tragedy from happening again, Qu Jingyuan learned from the painful experience and decided to cut off the bad relationship between the Demon Lord and Xie Fu at all costs. Unexpectedly, later on... He became the black moonlight of good and evil. Everyone couldn't love him and went crazy.
