Hero-in-the-making Veteran Kim Hansoo finally defeated the demon king after 10 years and is now ready to go back to earth. But the admins and teachers failed him in the report card and brought him back repeatedly to take the exam. Multiple times. Now he's an OP Hero/Villain who just wreck havoc anywhere in the guise of hero till he makes it out of there.
Really WILD read. The MC becomes OP as he repeatedly do the exam training and keeps getting good luck. Action-packed, satisfying killings and a very logical MC makes it entertaining. The thing it, it's becoming very draggy in the later chapters in a way, as it seems as though you can't see the plot ending. Or it's just a loop.
