Was That Monkey

From publisher blurb:

Followers of the Monkey King were fiercely dedicated zealots until the end of their lives. When they died, so to did the treasures they carried. The Monkey King, figuring another follower would pick up where the others have left off, was too busy sowing chaos to realize he eventually walked alone.

Several centuries have passed and one of these artifacts has “woken up” in a roadside shrine near where the Heroes make camp. It cries out to its master, who comes calling.
