A Journey Through the Myriad Worlds, Beginning with Kung Fu Panda

Her name is Liang. At the end of the Dao, beyond which there was no path, she became the one and only across the myriad heavens. And yet her presence could be found throughout them all. She created a universe as her home, turned her blood into children, and sent them across the myriad heavens in the hope that they would discover a new path...

Simply put, the protagonist's mother sends him traveling through the myriad heavens to seek a new Dao. (You can ignore this line, since the worlds don't have to keep getting more powerful. He can visit any kind of world, even an ordinary one. The author will just give the protagonist a few scenes of Dao enlightenment.)

The protagonist, Liang Qi, starts out in a beginner's dungeon: Kung Fu Panda. He creates his own martial arts there and becomes invincible, never expecting an enemy from beyond the heavens.

(Zootopia is complete, and White Snake is in progress. These are among the worlds the author has decided to include. The protagonist has a seductive charm, since it makes the story easier to write.)

Multiple heroines. The story begins in Kung Fu Panda. The author wishes to make clear: furry characters; all characters are adults.
