Yun Gui, who lives in seclusion in the mountains, lives alone in a thatched cottage, and life is desolate. On his way up the mountain, he saves Chilan, a nine-tailed fox whose strength has plummeted due to an accident, Xuanji, a down-and-out Demon Lord, and Lin Suwei, who has no immortal power left. Three powerhouses who once shook the three realms take refuge in the humble cabin. Chilan is gluttonous and playful, the Demon Lord is introverted and hardworking, and the fairy does not understand mortal ways and often causes funny incidents. Yun Gui handles three meals a day and mediates the conflicts between them. The high-and-mighty figures of the three realms indulge in the mortal hustle and bustle, and the lonely Yun Gui also gains a bustling and secure sense of belonging.
