- Description from Novelupdates

The sky was painted gray forever. The light of the sun was restrained. The darkness of the night was deeper than ever. At such a time, he belonged to a class people didn’t even recognize as ’human’. He was at the bottom of the social stratum, a slave. And when his only family was taken away from him... he no longer had a purpose in life. Yet, he clung to life because of his promise. And he set an impossible goal for himself, just so he’d have an excuse to live. When he finally reached a place he never expected to be, in pursuit of a purpose he expected to fail and die miserably trying to fulfill... he awoke to a night that would change his entire life. He was an insignificant fly, a mere speck in the destruction of the Empire. But he... survived. And, despite being a slave, he gained the blessing of a king. Or rather, the curse...

In the Abyss, all beings are imprisoned, struggling bitterly to survive. One day, in the eternally dark lower world, a young boy has a chance encounter and catches a glimpse of the upper worlds. He is fortunate to witness wonders beyond even the most beautiful dreams. Realizing there are worlds beyond his own, he refuses to settle for mediocrity and vows to ascend to the top step by step.
