That's the title?
Time-Limited Genius Dark Knight on Webtoon its up to chapter 82 with 83-85 with Fast Pass and you can watch an ad to read those three latest chapters.
Yes that's it thx for the title it slipped my mind.
I knew it was familiar man, that's interesting though, seeing a different perspective
Was it already on chapter 90 here in mangago? Terminally-Ill Genius Dark Knight
Oh, I'm talking about on Webtoon. I mean, you can support the author there or reread it on webtoon.
I think this story is from Nox fon Reinhardt, it's on, asurascans but this time, it's about one of his many friends that was in that necromancer.
