[Romance skipped] After transmigrating into a cultivation world, the original owner had a noble identity and incredible talent, yet he was a lovesick simp? What does that have to do with me! Simps meet bad ends. I'm not going to be one! And this fiancée of mine is a brother-spoiling sister! No way I'm keeping her! Just as his fiancée shows up to extort him, The Destiny System activates! It can see through other people's fates! Well, would you look at that: this fiancée's fate is toxic, and there's infidelity mixed in! She's threatening me with breaking off the engagement? What a coincidence. I want to break it off even more than you do! Wait, this woman has already secretly pledged herself to the protagonist? Anyone who opposes the protagonist is a villain? Who cares about being a villain? As long as the rewards are good, even gods can be taken down! The Favored Child of Fortune is blessed by the Heavenly Dao? Why would it bless someone who destroys worlds and devours the Heavenly Dao? The Heavenly Dao is sick! Seriously sick! Let me help you get rid of this cancer! If Heaven has no justice, I'll take its place! Change my own fate! Ding! Reward: the supreme cultivation constitution, the Primordial Dao Body! Change my parents' fate, and receive... Jiang Sheng: Wait! Protagonist, don't die yet. I haven't maxed out my rewards! Let me farm just a tiny bit more! His fiancée fell to her knees, sobbing. “Jiang Sheng, I was wrong. We can start over...” Under his fiancée's disbelieving gaze, Jiang Sheng chuckled and swung his sword. “I'll take that reward you brought right to my door!”
