I wandered into a room, there was a strange night that 14 had been placed in the single-sided mirror. On the floor "and then teaches how the arrows should go bigger." Laser pointer has been placed and written notes and had written a small arrow on the floor. A ~ D will be the next way to go anywhere.

Notes on Puzzle
You're given an arrangement of mirrors, and a laser light source. When the laser bounces off the mirrors, it sketches out an arrow, which points in one of the four cardinal directions. A fairly straightforward puzzle, as long as you're used to drawing light paths bouncing off mirrors.
