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”.

Every human has their Personal Jewel of power, when awakened it can either be an Elemental Jewel or Physical Jewel. They circle the right and left wrists like bracelets of power.

Heavenly Jewels are like the twins born, meaning when both Elemental and Physical Jewels are Awakened for the same person, the pair is known as Heavenly Jewels.

Those who have the Physical Jewels are known as Physical Jewel Masters, those with Elemental Jewels are Elemental Jewel Masters, and those who train with Heavenly Jewels are naturally called Heavenly Jewel Masters.

Heavenly Jewel Masters have a highest level of 12 pairs of jewels, as such their training progress is known as Heavenly Jewels 12 Changes.

Our MC here is an archer who has such a pair of Heavenly Jewels.
