Swing a Sword and Become Stronger (by God Level Chicken Master)

Bai Yu found himself transported to the world of One Piece, where he unexpectedly activated a unique system — the Strongest Swordsman System. Without the need for traditional training, every swing of his sword enhances his skills and might! Embarking on this unconventional path, Bai Yu committed to a daily regimen of sword swinging. In fact, with just one thousand swings, he already awakened the Six Powers, Rokushiki! Throughout history, the legends of the world have sung his praise. None shall get in his way. From this moment forth, Bai Yu's fame will reverberate throughout the pirate world, his name synonymous with unparalleled strength.
