The History of Using Villains to Defy Destiny

I was originally just a cannon fodder who cooperated with the male protagonist to show off, but I accidentally awakened the villain system. As long as I knock off the halo of the male protagonist and complete the task of supporting my wisdom, I can accumulate merit and return to my own plane. This time I not only want to change my fate of becoming cannon fodder, but also improve the IQ of everyone in the plane and bring the order and rules in the plane back on track.
