Nezha Palace
Long ago, the temple was used to house the Map of the Ring Samadhi, which was guarded by Nezha and kept behind a powerful seal.
Soon after the Lady Bone Demon revealed herself to Monkey King, he went on a quest to find a weapon strong enough to defeat her for good, which lead him to the Temple of Nezha. After declaring that he needed the map, Monkey King forced his way through the seal, stealing the map and destroying the temple. The fire ring of samadhi is one of the strongest weapon according immortals.
