Cultivating Immortality Across Anime Worlds, Starting in Academy City

Academy City possesses technology half a century ahead of the outside world, and has acquired all kinds of names as a result.

The Island of Wisdom, the Treasure Trove of Science, the Cradle of Talent, the Paradise of Magic, the Center of the World, and countless other unbelievable titles. Here, technology is a century ahead of the outside world; here, there are countless individuals with special abilities; here, the fates of people all over the world are in its hands. But above all, this is a school, a school as vast as a city.

After transmigrating into A Certain Magical Index, being taken in by Eastern Taoism, and obtaining the Boundless Fantasy System, the protagonist gains five cultivation methods from the start: Eternal Life, Shrouding the Heavens, The Sun God, Journey to the West, and Infinite Terror. See how he reaches the summit and leads all living beings to become immortals.

It all begins in Academy City. A crossover through the myriad worlds, no saintly heroics, somewhat dark. Enter at your own risk.
