The Villainess Empress Became the Heroine of My Script

Jiang Chen transmigrates to a martial arts world and binds to the Script System from the start. As long as he completes the plot of each episode, he can earn System rewards. Script: I Really Didn't Mean to Be the Big Bad. Episode One: Bully the heroine! The heroine turns out to be his junior sister, and she's actually the reincarnation of an evil empress. Episode Two: Shoot the heroine with a hidden arrow! It's not like I want to shoot you with a hidden arrow, but the rewards for following the plot are just too good! Episode Three: The male lead appears. Won't I be dead by the third episode? If that's how it is, then I'll just have to take out the male lead outside the script! Episode N: I really didn't mean to be the big bad! What the hell? Has this character gone completely off the rails? How did the evil empress become an untouchable heroine, while I ended up as the big bad everyone wants to kill?
