*
After the antagonist Demon Lord Yuezheng Yan reborn, he planned to follow the trajectory of his past life, to bloodily cleanse the hypocritical Master at Cloud Nine Peak and exterminate his malevolent original family.
But on the first day of joining the sect, he was hoodwinked by a Senior Sister he had not met in his previous life and ended up at Xiaoyao Peak.
The Senior Sister said, “Join Xiaoyao, and I'll have your back, Junior Brother. All you need to do is be happy.”
Yuezheng Yan nodded and believed her... evil intentions!
3 two-hour periods after joining Xiaoyao, he was buried alive by Lu Xingyan's alchemical explosion that destroyed his Immortal's Cave.
4 two-hour periods after joining Xiaoyao, he was turned into a snowman and had his hair scorched by Lu Xingyan.
12 two-hour periods after joining Xiaoyao, he was brainwashed by Lu Xingyan and even did odd jobs for her.
Whenever he protested, Lu Xingyan would look at him gently, “Senior Sister is doing this for your own good.”
Yuezheng Yan scoffed at this.
Nice try, Lu Xingyan. Do you think I can't hear your mind?
Your mouth says you love me, but your heart and that Old Sixth System scheme every day to stab me to death.
You escape first when the auction house explodes.
You don’t care when your Junior Brother is struck by lightning.
You don't even bother to pull me out when I fall into the water.
Claiming you're tired and need to rest, yet you go off to enact a tearful reunion with the original female lead, your White Moonlight, displaying your deep affection!
You're having a great time.
Leaving me squatting on the ground, digging Poisonous Mushrooms for you until my hand cramps.
Once I return to the Magic Realm, I'll send you to cultivate Magic Lotus!
Yuezheng Yan sullenly returned to the Magic Realm.
Until one day, he overheard a conversation between Lu Xingyan and the Old Sixth System.
Old Sixth: Host, the Little Antagonist has betrayed Xiaoyao Peak and run off to the Magic Realm. We’ll replace him with a more obedient Little Antagonist for you~
Yuezheng Yan: Old Sixth, shut up!
Senior Sister, don't replace me. I'm rolling back right now.
