Scared crazy! Son, this is obviously fake! I heard this in elementary school! If you go to my old school, you will never go out in your life! We stopped two bodies as soon as we entered the building! The classroom is full of bottles filled with heads and various organs. Sometimes when you don't eat in the morning, you hide behind glassware and eat face to face with your head! Haha, I'm from medical college! Even in very hot summer, the experimental building will be bitterly cold! This is not afraid! It's never too late to see a video taken by someone with a mobile phone next time! It is estimated that Newton's loneliness is called three missing one!
