With the rising tide of steam power and machinery, who can come close to being a Beyonder? Shrouded in the fog of history and darkness, who or what is the lurking evil that murmurs into our ears?

Waking up to be faced with a string of mysteries, Zhou Mingrui finds himself reincarnated as Klein Moretti in an alternate Victorian era world where he sees a world filled with machinery, cannons, dreadnoughts, airships, difference machines, as well as Potions, Divination, Hexes, Tarot Cards, Sealed Artifacts…

The Light continues to shine but mystery has never gone far. Follow Klein as he finds himself entangled with the Churches of the world—both orthodox and unorthodox—while he slowly develops newfound powers thanks to the Beyonder potions.

Like the corresponding tarot card, The Fool, which is numbered 0—a number of unlimited potential—this is the legend of “The Fool”.

Mythical Abode Mountain, Cloud’s End Cliff, the most dangerous of Azure Cloud Continent’s four deadly areas. Cloud’s End Cliff’s base is known as the Grim Reaper’s Cemetery.

Over countless years, the number of people that have fallen off this cliff is too high to count. None of them, even three stronger than god masters, whose power could pierce the heavens, have been able to return alive. However, a boy that’s being chased by various people because he alone holds a priceless treasure jumps off the cliff, but instead of dying he wakes up in the body of a boy with the same name in another world!

This is the story of a boy wielding the Sky Poison Pearl, cultivating the strength to oppose heaven and earth, a lord overlooking the world!
