This is the story of a little barley that took five thousand years to attain enlightenment and become an immortal. The reason why she became an immortal was because her master said something to her when she was young (when she was clearly still a small and fat barley), "Zhuran, when you become an immortal, my master will come to pick you up."
Ah, this is obviously when the apprentice was young, the master had his eye on this unusual fat barley! Therefore, Zhuran has been going back and forth between the human world and the underworld for the past five thousand years. And the story is what happened during these five thousand years. This is a short article, to be honest, it is a bit sensational, but our little Zhuran is very cute!
