Different things
"I've got it grandpa, please take it." Faust was curious but brings the book that seems to be some kind of manuscript to his grandpa, but Gus didn't take the book, instead he told Faust to read and study the first ten pages.
"Read what it says on the book cover" Gus told Faust.
"Hmmm... Unholy sword arts? That's what it says." Faust reads carelessly while looks up at his grandpa with a questioning expression appearing on his face.
"I'm going to teach you how to use a sword" the words said by his grandpa echos in Faust's ears, while he is mopping the floor with a long broomstick but in place of the brush and stiff fibers, this broom stick has braids of cloth as brush. And when it's soaked in water it gets wet and makes it hard to move the broomstick even on the ground because of the massive amount of weight on the braids and for a kid like Faust it's like tons of weight to move.
