The Genius At The Swordsmanship Academy

When I opened my eyes, I found myself possessed a character from my own novel.
And not just any character, but Ernas Lanzstein,
the ‘fake genius’ who could only mimic others’ swordsmanship.
I was now trapped in a desperate situation att the Lichtnauer Swordsmanship Academy, where the conspiracy of the six great swordsmanship families unfolds, I must survive as Ernas, the villain despised by everyone.
However, with the awakening of a new ability, I now have the chance to become a true genius, not just a fake one.
