Why is this chapter seems really strange? I feel like there's a lot of characters i missed. I don't even remember this slime and this one envoy appeared in whichever chapter. And this werewolf??
I even reread ryouma arc
IIRC that immortal potion is started as gunpowder as a result.
Yeah, the invention of gunpowder in china is just a mistake from making immortality potion. I can't help but laughed someone drank gunpowder XD
