Ruins, 36th Underground City.
The 36th Underground City of the ruins in Fireflame City is quite a famous one.
This area was among the first batch of underground cities excavated in Fireflame City. It was discovered at the inception of the Adventurer Guild. Many of the other cities from the same batch have been thoroughly explored, yet this one remains almost completely unknown.
Initially, this underground city was no different from others when it was first excavated, and the Adventurer Guild conducted explorations as usual.
Unexpectedly, during the exploration, they discovered a terrifying Undead Giant Beast, the Bone Dragon, inside the city.
Facing such a powerful creature, only seen in tales, ordinary adventurers with mere mortal bodies were no match. When the Undead Dragon Breath carrying an aura of death swept through, any adventurers facing it vanished in an instant.
