Babe I also felt the same way since its been so long since I've read manhwa so my imagination and attention span got ruined but Im not joking once u reach atleast around 260+ of the novel you'll be ON it nonstop even at the start of part 2(I believe 190+ onwards)
Also Lil spoiler
During the chapter 265 well..yeah anyway chapter 300 is where the ANGST really hits like a truck(dw they're all happy at the end anyway and another spoiler once the apocalypse is destroyed powers/systems will be gone too) it was so gut wrenching

I mean I tried reading the novel, but I can't imagine the action in my head. I really want to know what's ahead tho ╥﹏╥
