Jian Ci is the light. An S-class Esper, his powers ripple with the warmth of a thousand suns, his smile a blinding beacon that draws humanity, and hope, to him like moths to a flame. He is the Sun, a magnetic force of nature, utterly unaware of the abyss that gazes back.Yu Xi is the dark. A shadow with skin, a man who walks through life with a silent, consuming emptiness, broken only by a singular, scorching singularity... Jian Ci.He is the Abyss, a dark constellation orbiting a single star, and his existence is now defined by the answer to one terrifying question.How far are you willing to go for him?Yu Xi’s response, spoken as clearly as a death sentence.“To hell and back.”This is the story of an impossible equation: Light + Darkness = ?It is a love that warps physics and morality, a descent into an obsession so profound it threatens to rip the very fabric of their world.Yu Xi knows their combination is impossible, a contradiction that should result in utter annihilation. Yet, with a quiet, terrifying devotion, he is prepared to burn the world, his own soul included, if it means securing his star.

In the year 2093, mysterious energy known as mana descended upon Earth for the very first time in millions of years. People began to spontaneously awaken, allowing them to gain supernatural abilities, classifications, and affinities.

Simultaneously, dungeons with immaculate treasures and horrid monsters began to appear all over the world, forcing humanity to stand together in order to survive.

Lloyd Elrod was a simple boy at first. He was a boy with no power and little to no social standing, yet that all changed on the day before his awakening ceremony. The day he became what the humans and the other races saw as a monster.

[Welcome to the Void]

It was the day he became a Void Walker. A race capable of growing faster than any other. A race with individuals capable of putting an entire civilization created by a multitude of races on the brink of collapse and walking into the Void itself.

Having become a part of the most wanted race in the universe, Lloyd is forced to hide and fight to keep his freedom. In order to not be restrained by those he once saw as his brethren, he must become strongest.

Will Lloyd be found out? Will he finally earn his freedom and have control of his own fate? Join Lloyd in his journey of joy, sorrow, grief, and pain as he climbs to the top and becomes the most powerful creature in existence.

This is an alternate history. Decades after the fall of the Eastern Jin Dynasty, the world is still in chaos, although there is hope for reunification.
