I know they say that Demons can only be killed by either the sun, nichirin blade, or wisteria poison, but I've been thinking, even if the Demons can regenerate from anything, they need to have at least a single cell remianing to regenerate from, as demonstrated by Muzan in the Yorichi flashbacks, when he exploded his bdoy so he could scatter his flesh around before he got disintegrated. So if you used an extremely corrosive substance or a fire that destroyed their cells faster than they could regenerate them, and complete cell destruction were to happen, would they be able to come back from that? I know it's not a plausible option for the heroes to use, since Demon Slayer takes place during the 1920s, but it's interesting to think about how well the Demons' powers would hold up to modern technology. Hell, UV lamps were invented back in the 70s, so I think the author knew what she was doing when she set the timeframe for the setting.
