Those monsters have nothing to do with the ones from a decade ago, said Engi.
We'll have to kill the leader to get to the heart of the issue. I believe he dwells in the depths of the Bamboo Heart Pavilion.
Before you face him, you'll need two items.
You must get the Qibanqu Jade and Broken Pieces of Tianqi Sword stolen by the Sakura Wisewood and Nether Blood Princess.
You can find the Sakura Wisewood around the Triangle Temple and the Nether Blood Princess in the Bamboo Heart Pavilion.
The Qibanqu Jade was originally a rare treasure kept inside the temple, and the Heavenly Sword was carried by Master Sakurai when he was alive.
These two treasures can ward off the demons. However, the Qibanqu Jade was stolen, and the Heavenly Sword was destroyed after falling into the wrong hands.
The Broken Pieces must be retrieved and forged together. When the Heavenly Sword is rebuilt, it will once again carry an incredibly strong, holy power.
