Behind the glory of "Journey to the West", there are still a group of forgotten little monsters. They live in Langlang Mountain and work at the lowest level, but they secretly hide a huge dream - to go on the journey to the west again, like their idols, and become indomitable monsters.
Shi Hou'er wants to prove that he is not the most useless monkey, Zhu Xiaofei wants to impress his sweetheart, Sha Xiaotuo just wants to find a clean place to sleep, and the old sparrow-turned-master can't even recite scriptures, but stubbornly believes that "all living beings are equal".
This is not a story about slaying demons, but the stubbornness and warmth of a group of little people. They had nothing but never gave up on each other.
