That hay fork must have been made out of thin and hollow aluminum, or else the kid must have had super strength/magic strengthening or something to make it deform after charging against essentially a brick wall like a crash test dummy, and come out of it unmoved and unfazed. Otherwise, that's not how physics works.

Overall, another pretty annoying chapter showcasing how dimwitted and naive the protagonist is. I hope they get over this speed bump sooner than later.
