Travel Between Worlds

A man who asks himself "when will death come" every day in his ordinary life attracts an inexplicable existence. "Are you longing for death? Why?" The boy replied, "The same routine allows me to predict my future life and makes me long for death." "So, how about traveling to other worlds? It's at public expense." The inexplicable existence said. "That's great, but why? I'm just an ordinary one among billions, why me?" The boy asked. "Because it's boring. Immortal me. The long years are boring. But maybe you will bring me a little joy." Inexplicable "Ah, that's really an honor." For the first time in the boy's ordinary life, there was a twist. "Then go ahead. I will give you the right to travel between worlds, give you a slightly higher intelligence than ordinary people, and give you three days to say goodbye to bring me pleasure. But be careful not to die!" The voice was as calm as ever, but with a hint of malice or... Fun. In this way, the young man bid farewell to the ordinary life and embarked on an endless journey.
