Other Daoists make pills with thousand-year-old lingzhi, ten-thousand-year-old cinnabar, and long retreats in immortal mountain caves.
Xu Changsheng makes pills with foot wraps and bathwater, setting up his cauldron in a busy marketplace to refine garbage.
He transmigrates into the Song Dynasty as a Daoist burdened with debt. From the start, all he has is a broken incense burner, but the System tells him: Everything can be refined!
(This is a humorous novel about people mistaking the ordinary for the extraordinary. In a nutshell: while other Daoists are still gathering herbs in the mountains, Xu Changsheng has already used Bianjing's trash to forge a Song Dynasty myth.)
