I live in the great kingdom of Sri Krishna Devaraya, he don't have any child so he said that whoever finds the one I tell about will be the next king.the entire kingdom was discussing about me and the discussion went viral throughout the kingdom. Everyone wants to know who I am. so I gave them a riddle "My size is as big as an elephant and I weigh absolutely nothing. what am I?". whoever solves this will be the next king.
