It seems to be a HxH G.I., except for the falling drunks

Junyou is drinking Bep?! Don't tell me she turned Hibiki into a delicious Russian alcohol and is consuming her. Hibiki NOOOOOO!!

It could be a joke - Suntory makes a whisky (which it looks like a bottle of) called Hibiki (same kanji).

Yeah, pretty sure it's an HxH reference of Greed Island. There's a part where Gon punches the world tree to shake all the bugs down and find some kind of special stag beetle, though whether it's silver or not I can't remember.
