How long our lives could be

Suddenly I heard a clapping noise. It sounded like a creature marching. I quickly ran up the stairs and stared out of the window to the front entrance. A swarm of demons were walking Infront. My eyes widened and I blinked to make sure that I wasn't hallucinating. I opened my eyes to see some of them glaring at me. Suddenly a ring echoed across the building. I walked back and bent over to see. on my left at the first floor, the door fell. Suddenly everyone starting screaming as the demons entered. I looked forwards and realised that a demon was climbing up the stairs. It's swollen arms left a liquid which melted each step. I turned back and ran the corner. I sprinted across the hall in fear. Screams and the sound of blood splattering against the walls could be heard. I looked back to see that the demons had climbed up. In a rash decision, I used fifty percent of my magna to shoot a blast. The demon clawed at it's face, desperately trying to wipe out the flames. I turned back and turned through another corner. Corpses were piled on top of eachother and the murderers ate their flesh, sucking out the blood. Some of them dissected the corpses and stored them in their mouth. I waited until they went and tried to jump over the bodies. I froze as my foot set into the bones. Stains of blood could be seen and bits of flesh remained, stuck onto the bones. I closed my eyes and went across. I encountered another stairway and jumped across. I tried to remember where the garage was. I then felt a tap on my forehead. I looked up to see a small demon chewing on a bit of flesh. I shrieked and ran. I nearly tripped trying to look back. It was on my leg. Shook, I let out the rest of my magna. The blood of others scared me. The creature fell on it's back and frantically waved it's hand before dying. My leg had a severe burn wound on it. What was wrong with these demons. They looked way different than the ones I had seen before. I tried to run, remembering where the garage was, but my leg gave in. I tried to run again in vain. I limped towards where I remembered it was. The whole time I was in fear of being attacked since my magna had ended. When I got there, 4 of the 15 cars were full and the rest had one to five open spots. I climbed up with one leg which took a lot more strength. I looked back to see many others running. Some of the demons found us and began to yell out which drew out many more of those strange demons. The engine began to rumble. One of the cars went. The people started running faster. I then saw Epor. Time seemed to slow down as he reached out. I extended my arm to try to save him. A finger clawed deep into his cheek. I hesitated. In that very second, the demon pulled his head back and he fell. I watched on horror as they clawed of his body. I began to wonder just how long our lives could be.
