Black blood demon

It was at night when Dennis and his friend where about to sleep they heard a strange voice at their door step but they never mind because they thought it may be their neighbor but spectrum who was one of Dennis friend saw a blood rush into their room then he told his friends to look at the floor, then they saw a blood rushing towards their bed then Benjamin tried pepping through the door then "he saw some people who don't think they are from this planet" he said immediately they heard they climbed up the roof they escaped but as soon as they gotvout of the building they saw so many of them and immediately they start running and shouting for help but no one came out Dennis could run faster than all of them but he stopped and waited for his friend cause he has given them so many gap the demon was following them at their back and they hid in at the back of a tree but it didn't work they continued running until they saw some equipment that they can use to fight the demon but Dennis was so afraid that he told them to drop and run they didn't drop the weapon but they ran faster than they ever did at this point they where too tired to run so they held each other maybe they could move faster than before Dennis who was the fastest carried Benjamin cause he was too tired, Dennis was the oldest among them so he knew how to take care of himself and his friends so he told them not to worry that they would be safe and they where no longer worried but kept on running for their dear life spectrum who could no longer continue fell and asked for water but no one have so Dennis dropped Benjamin and carried him again, so they hide inside an uncompleted building for so long
