Overpowered Undead System

*** I do not own this cover image. I repeat I do not own this cover image. Credit to the person who created it, I think it is a really cool picture.. "Riden....Riden come here boy." A little boy came out from a corner and slowly inched towards an old man lying on his deathbed. "Listen, soon the world will change.... I need you to promise me that you will not die nor abandon your humanity when that time comes." "Yes sir yes sir just please don't leave me." Riden squeezed the old man's hands and started crying. "I-I don't want to be alone!" "I'm sorry boy but I have no choice in this matter. But please, just promise me you won't." Riden nodded his head and the old man smiled. His breath getting raspy and his hands start to lose their grip. Riden started crying louder. "Please don't leave me." Riden's voice got lower and lower and soon his cries died out. He turned around and left the small shack they had with a face full of determination. "I promise grandpa, I promise I won't let you down!" ***
