I'm looking for a story where the female lead is distant but gentle toward others. She can be cold and bloodthirsty too, as long as she isn't stupid. Anything goes.
There is no cp, the system is very broken, except for being able to travel through time, there are no other functions, and you can't even catch the plot. The heroine is mentally strong and her force level soars quickly. The purpose of torturing a scumbag is: as long as she beats the person until she can't speak, she will win whatever she says!
