Falling into a Disadvantage! Full-Strength Luffy and Teach Using Only a Single Fruit

Science shows that the bones on a human forehead are far harder than the bones on a fist!

The size of Teach's fist was already about the same as Luffy's head, and accompanied by tremendous force, Luffy's face also carried massive kinetic energy. That youthful face was instantly deformed by Teach's punch, but thankfully, because
