Transmigrated into the Villain's Senior Brother

I transmigrated into a cultivation novel about a peerless male protagonist and got bound to a System. The System issued a mission: [Find the male protagonist.] Me: "Got it. Find the male protagonist, then cling to his coattails." System: [NO. Find the male protagonist, break his legs, take his golden finger, ruin his opportunities, and steal his romance.] Me: ??? Later, just as the System's missions demanded, I did every evil deed imaginable, stole his opportunities, and took his wife. The male protagonist came after me for revenge. I thought he'd torment me to death, but instead, he tied me up, took my clothes off, and tormented me in bed until I was barely alive. "You stole my wife? Then you can be my wife." Me: ??? This isn't right! . Theme: Freedom is above all.
