Xiao Fan, whose parents were both dead and living alone, found the bathroom mirror at home knocked by his grandfather who had been missing for nine years in the middle of the night. After learning that his grandfather traveled to another world and was preparing to rebel, Xiao Fan worked hard to make money to raise soldiers, horses, food and grass for his grandfather in the other world through the realm of space and underworld. Grandpa also passed on Xiao Fan's powers of clairvoyance, mind control, invisibility, teleportation and other powers through the void realm. Relying on the superpower given by his grandfather, Xiao Fan found that he was invincible in the city. Grandpa also succeeded in rebelling in another world by relying on the arms and weapons transmitted by Xiao Fan. Just when Xiao Fan was about to travel to another world to inherit his grandfather's throne, people from the Ninth Security Bureau informed Xiao Fan that there was another hidden reason behind the death of his parents.
