I Only Have F-rank Powers, But I'm Forced to Refine Everything

(Slow-burn dark novel, early chapters are slow-paced. The protagonist is occasionally unhinged. This is not a power fantasy. If that's not your thing, don’t read.)

In a single instant, the world was abruptly destroyed, and Han Yang died with it.

Bad news: The world ended, and Han Yang is dead.

Good news: He reincarnated — into a supernatural world!

Bad news: He has F-rank powers and just got kicked out of his family.

Good news: He has a cheat ability… and a second power!

Bad news: The second power is also F-rank.

The protagonist is dark and ruthless, willing to do anything to achieve his goals.

Not for the faint of heart. You’ve been warned.
