How much disaster can a time traveler bring?
-Petunia Riddle tells you.
Note: It is a counter-text, the tone of which is half sadistic in the first half and sadistic in the second half, slightly dark. The main theme of the whole text is how to kill the time-traveling Mary Sue who thinks she is very naughty and kills people all day long with her golden fingers.
Mary Sue also wants to thank you with dignity! Not every Mary Sue finds it fun to torture innocent people to death!
This hafeihaha, Harry is completely destroyed! ! !
