What's the longest time you were hyperfixated on some novel/ webnovel/ webtoon

For me it's tgcf- tian guan ci fu- heaven official's blessings. Super hyperfixated on it since last year and I'm still digging it. Oh and murderer Llewellyn's candlelight dinner invitation, been 6 months.

These are absolute masterpieces. Sometimes I get so excited js by thinking about it to the point I wanna destroy everything
