Tie Dan was scurrying around the palace, and although he didn't find the Nine Cauldrons, he did find a secret chamber.
Surrounding him were skeletal remains and blood, a chaotic mess, but the passage to the secret chamber was clean and tidy. It seemed as if all the demons coming and going were blind, not noticing this part of the palace. This must qualify as 'secret'.
So Tie Dan went straight into the palace, pushed the door open, and entered. Inside, he saw a dragon bed and jade carriage adorned with brocades and a canopy, decorated with fragrant herbs, gold, and silver. In the grand hall, a jade dragon relief was holding a Bright Pearl in its mouth, emitting great light that illuminated the lifelike corpse on the bed.
Well, it should be him.
Tie Dan took a closer look, judging from his attire and facial features, he guessed the corpse was likely the Kan Country Master.
