Yondome wa Iya na Shizokusei Majutsushi - Ch. 73 - Demon King's Blood

[naphack]

She mentioned the 9th seal or something right? Wasn't that like a coffin to seal the demon king that the MC accidentally broke open and consumed the contents/soul of? I thought he gained a weird title or skill or something at the time.

The capital of the Hartner Duchy (I believe it was called Nineland but don't quote me on that, the name barely appears in the novel, usually the location is just implied when talking about happenings within the Hartner family.) is named after one of the champions, Nineroad. Just like Suzuki was called Bellwood because his name uses the kanji for bell and wood, Nineroad's kanji literally read nine roads but I can't quite recall what her actual name was.
And yes, the demon King's blood was sealed under the Hartner family's Castle.

It gets explained eventually but TLDR

Spoiler

Van is what they call a Guider in that world. Basically, some individuals are so influential that they can buff others just by interacting with them. Notice how Van's allies inexplicably gain new powers from out of nowhere. All the Heroes that were summoned to defeat the Demon King were guiders too. And so is Blue Flame Heinz. But as a side effect of this ability, anyone Van guides will be transferred away from Rodcorte's cycle of reincarnation and into Vida's.

Again, this is mentioned much, much later!

That’s an insanely cool detail. Thx for the explanation

I'm up to chapter 394 of the light novel and I don't remember this at all. When was that stated?

I'm quoting based on a comment I read a while ago, I'm probably misremembering it or it could have been incorrect in the first place.

That was another fragment of the demon king, his blood. Van simply integrated it without any issue, so it was glossed over. It would have been impossible for anyone else. Why is the real question that OP was asking.
