Toaru Majutsu no Index: New Testament - Volume 14, Chapter 2: Freeloaders Tend to Grow in Number - Cannibalization.

Fate had never been kind to Ji Ning. Wracked by illnesses and infirm his entire life on Earth, Ji Ning knew early on that he would die as a teenager. What he didn’t know was that there really was such a thing as life after death and that the multiverse was a far larger place than he thought.

A lucky twist of fate meant that Ji Ning was reborn into a world of Immortals and monsters, of Ki Refiners and powerful Fiendgods, a world where Dynasties lasted for millions of years. A world which is both greater… and yet also smaller… than he ever could imagine. He would have the opportunity to join them, and in this life, Ji Ning swore to himself, he would never let himself be weak again! The Era he was born into was a Desolate one, but Ji Ning would make it his era.

It all started when the protagonist downloaded a game called “The Fool (Beta Version)”. Since then, his life has changed.

A simple text adventure game with no graphics, no music, only lines of text and countless options, but every option in the game will affect the player’s fate, because on the opposite side of the game is a real unknown world!

Players cannot enter the different world, nor can they see the scene of the different world. They can only experience what the game characters see and hear every step of the way in the different world through the form of text.

With the progress of the game, not only the rewards in the game can be realized in reality, but also various abnormal creatures in the game began to appear in reality.

Until one day, the game will be tested globally.

An era in which all people explore and hunt treasures in different worlds through “text adventures” is quietly unfolding!
