Series is most similar to the Korean Style Tower Genre mixed with the Wuxia Genre.
While not of course being the same.
- Post apocalyptic world.
- Seems to be out world, but was hit by the "Nightmare Spell" instead of Towers.
- Pulled into the Spell, those who survive become Awakened with Aspects (traits), Abilities and of course Tiers of strength of them.
- Wuxia path towards divinity like leveling system (but using 7's instead of 9's).
- "First Nightmare", "Second Nightmare" and so on instead of Tribulations like in a Wuxia series.
- Lots of well done battles.
- Good character growth.
- Comic relief moments.
- LOTS of mental and physical torture to the point of being depressing at times.  LOTS of hardships and pain.
- Seemingly overpowered abilities to of course only learn just how much of a frog in a well one really is.....

Seems to be one of the more popular EN Web Novels right now.
Fun read and recommended.

Would like to see proper volume split Epub's if possible.
