Zhang Can, a poor lad from Qingya Mountain, has one great dream: to eat steamed buns at every meal. That is, until he meets the down-on-his-luck half-immortal Mr. Su while starving. In exchange for a whole roomful of buns, he pesters the man relentlessly until he takes him as a disciple. Thus begins his absurd life of cultivation, where cultivating immortality means fighting over buns: he practices standing meditation so he can run faster to grab them, learns fire-starting spells so they taste better when roasted, and even gets caught up in the battle for Qingya Snow Fungus because he heard it could be traded for a mountain of buns.
His half-immortal master wants to teach him to fly on a sword, but all he wants to learn is how to deliver buns on one. When a senior sister from the Qingyun Sect brings him a cultivation treasure, his first question is, "How many sweet buns can I trade this pendant for?" When Blackwind Hall assassins come after him, he brandishes a burning pine branch and shouts, "Anyone who dares steal my buns is getting roasted to a crisp!" Even Ahuang the Shiba Inu has been led astray: he cultivates immortality just to chew more dried sweet potatoes, while Heitan the black horse aims to eat sweet potatoes at every meal.
This is a hilarious adventure starring a cultivation crew of foodies: the immortal sect's secret treasure is a bun exchange voucher, sect rivalries are chaotic bun-grabbing brawls, and even the ultimate goal of breaking through Heaven's Gate has become making sure the Celestial Court's bun shop has an unlimited supply. After all, for Zhang Can, the end of the path to immortality has never been ascension. It's buns without end.
