Honestly the manhwa confuses me so much because things that should've been revealed much later is already being revealed, like Baek Dohyun's talk with Tyra should've been revealed much later after the 90th floor but eh.
If I were to focus on just Tyra's empire attacking the tower then it'd be around 165-166

Does anyone has the link to the novel? I'm really curious about how the story will go
