The Spiralling Sewers Instance.
Inspired by roguelike games, a subgenre of role-playing games which emphasised on procedurally generated levels and permanent death of the player character, Jin had used a few ideas from them to create this particularly new dungeon instance.
While the Demon Rats would eventually disappear after enough cultivators had culled their numbers playing this particular new instance, it would give Jin a good amount of data to see if he should continue to expand this instance in the future as well.
As for now, this instance would work by allowing only one cultivator per dungeon instance. They would start from the top where they would find a porthole to descend down into the next, they would encounter those Demon Rats which would be roaming around the sewers.
