School Again

You have returned to your abandoned school to collect various items as keepsakes (pens, pencils, textbooks, notebooks, etc.). At first, the school seems empty, but soon you realize you are not alone. A blind undead teacher does not like visitors and kills anyone who disturbs the peace of the abandoned school. Although blind, the teacher has excellent hearing. He can hear your footsteps, the doors you open, and the items you drop, so be quiet. Good luck!
