Sui Sui, the little junior sister of Buzhou Mountain, is ordered by her master to go down the mountain to find five senior brothers and exchange token plates, but she is single-mindedly obsessed with mortal delicacies. Upon first entering Qingyun City, she gets into a conflict with the Zhao family because her meat bun is stepped on, single-handedly flipping a blazing beast carriage, accidentally bringing out the Supreme Token of the Myriad Realms Chamber of Commerce. In order to eat spiritual beast meat for every meal, she comes to Lingyun Immortal Sect, yet suffers contempt due to lacking spiritual roots. Relying on astonishing divine strength, Sui Sui breaks phantom arrays, lifts heavy pillars, defeats battle puppets, and even treats precious elixirs and magical treasures as snacks. As demon sects lurk and hostile immortal sects close in, the senior brothers who secretly protect her also gradually surface.
