Po's Chi needs to be reharmonized by means of musical kung fu, and time is of the essence, because Po must halt the Yaoguai, who are intent on stealing five musical instruments made by ancient masters in order to fight the darkness. The instruments would play the Eternal Chord (a harmonious song that transformed the earth from darkness and chaos to light and order), and then the wicked goose will use them to play a distorted, inharmonious song called the Anti-Chord which will destroy the world and un-create the universe.
