Contrary to the other instances, Jin was extremely confident that there would be no need for any fixes with this last instance and it would be to the liking of the twin shopkeepers Bai Xin and Bai Wan. This was because he literally had handed them his Weapons and Armoury Instances.
But for the two of them, this became a major headache. Bai Xin and Bai Wan would have prefered to become store owners in title, acting as mere of assistants for Jin. The dungeon supplier, however, had other plans in mind and was more than happy to delegate this task to fully concentrate on his dungeons. Begrudgingly, they were currently trying their best to memorise what items were in which section.
Not to be too cruel, Jin did assign some Red Panda NPCs to them if they had any questions and as workers free of charge (for the rest of December at least). The minor difference between then and now was that Jin had revamped the place a little.
