Ghost Story 2 What's the use of the picture drawn by the cloth bag monk?

Used to collect Cangling postal treasures. Click on the triangle below the mall in the upper right corner to view the collection. There are 4 kinds and 5 kinds of postal treasures in Cangling. Each collection can get one thing at a time. I remember that it was a prop of bone, intelligence, strength and agility +6, just like the East Emperor Bell effect in the package.
