It all Started When i was Jogging when i accidentally tripped and died. there, I woke up standing in a Cloud and met an old bearded man who was named GOD, he said: Sin, I accidentally erased your name Instead of the 90 Year-old man who was Living in a Cabin Your name was under it and accidentally erased it, To make it up to you i will send you to another world and give you extraordinary powers, How's that?. I said Sure, I would gladly take your offer to end my boring Life and Start a New Adventurous Life. So there you have it My New Journey Begins.
