Punishing Gray Raven OST Huaxu (华墟) ( Menu ver) Extended 九龙环城

From the Kowloong Metropolis event. Notably also used in the Lost Chapter event. Composed by AntiGeneral I think the title is a pun. Huaxu (华胥) is one of the titular characters of the event and the pronunciation of the title is Huaxu (华墟) (with different spelling). The song name Huaxu (华墟) possibly means Magnificent Market or Magnificent Village, probably referring to Kowloong. The Kowloong AI character Huaxu (华胥) shares her name with the goddess Huaxu. Second image is actually from Lost Chapter, but the majority of that event reuses music from this event and Nona Ouroboros Original mix: My Punishing Gray Raven Extended OST uploads:
