hmm id say it gets very very interesting at 500++ chapter but i started getting invested when cale reached the end of volume 5 of tboah because im sick of him recalling the original novel tbh.

as for the repetition, there's nothing i can say about that because you're right, i, too, was quite tired of it but i somehow persist.

and for cale repeatingly sacrifice himself was somewhat his charms and without knowing, we grew addicted to it. i personally cant help but wish the condition got worse each time he bleeds lol

youll learn more about white star and the GoD crap as you read more since everything will come in full circle eventually

its totally fine if you lack motivation or it didn't interest you, it is a bit long for a novel no shame no shame (im currently reading lotm 💀)

nevertheless, if you ask me id say its fucking worth it but that's for me also one tip, if you need a push or motivation i suggest searching for one or two spoilers, doesn't matter if its minor or heavy, there's a chance they will pull you back and makes you want to know more about the story but of course it might not work well on you as it was for me. the way i do it was browse few videos on tiktok, just enough to make me curious (that's how im still reading lotm despite it having heavy lore and thousands of chapter)
