I personally think the best part, and the selling point of this Manhua, is it's a simple plot. There is some kind of system that allows the main protagonist to move from world to world getting revenge on the ML and sometimes FL. However this keeps the plot relatively fresh. You don't drag out unnecessary drama or plot just to keep the story going, it takes exactly the time it needs to complete their mission then they move on to the next world. Obviously that can be a downside as well as you don't get a deep dive into anyone outside of the main character.
But overall great story with even better pacing
