Meaningless

"There are infinite stories and there are uncountable number of stories being created every second. How am i supposed to end them all" Silch asks with a bit of confusion. 

"Boy i thought you would be more surprised. There are a finite number of stories in this library not infinite an i believe you got the wrong idea of what a story is." The voice replies with a bit of amazement and disappointment in its mind.

"So there isn't a story about an random atom in a random blade of grass." Silch asks the voice.

"You are too smart and stupid for your age. only living beings contains stories, if there were that types of stories then 99.99% of all these books would be them and---"

"How must i end the stories. Do i need to take the books and write the ending? and how can i end all of them when many are being created every second." Silch asks cutting the voice while it speaks.

"You have all of time in The Library. Even if you die, your soul would end the stories. Do you really believe that your universe wouldn't be destroyed and your universe's time wouldn't end?, All you do is meaning less it will be destroyed, its is fated to. As of how to end them, by opening any book you would travel into them. You would take the role of a character, important or not. And you must end it, you have 2 methods. One is to end it the proper and quicker way, by the death of what the story revolves around. The second method is not recommended as it requires you to end it in a way you see it. you can choose the way in the story as you complete it, or you could chose not to". The voice replies.

" But the task needs to be recognizes by you as one with high difficulty, so you cant chose the method as a leaf falling of tree and landing on the ground. And also the task must be something that will change the main plot of the story, if there is any, so cant set it as you learning an almost impossible trick or lifting a large rock with twice your mass". The voice says, Obviously removing the chance of any exploitation .

"When do i start" Silch says while looking at the books, contemplating which one to chose.

"You can start when you want. You have infinite time at you disposal, The Library is called eternal for a reason but boy, you really are strange. Don't you want to go home, aren't you 14 years old in the time scale of your world, are you not". The voice asks with suspicion.

 "That is not you concert" Silch says with no emotion.

The voice didn't chose to question further and said with a small amount of excitement" You are now a Keeper of Stories."
