After three years of cultivating immortality, Wang Qinghuan is expelled from her sect because she is hopeless at even the most basic sword-flying technique. Just when she has fallen on hard times, she discovers a ten-thousand-year-old spiritual leyline hidden beneath barren land. Using its spiritual soil, she grows ingredients rich in spiritual energy and sets up a humble outdoor restaurant. She possesses a rare Food Spirit Root, the only one to appear in thirty thousand years, and her culinary skills are unrivaled across the three realms. She befriends a spirit beast named Xiao Kui, is secretly protected by her senior brother Rong Nian, and forms a bond with the aloof Demon Venerable Chi Xiao. Even her former adversary, senior sister Liu Ruyan, gradually lets go of her resentment. As she runs her restaurant, she repeatedly faces sabotage and schemes from competitors, as well as underhanded tricks in culinary competitions. Yet she relies not on cultivation but on a single meal to settle disputes and comfort people's hearts. She eventually claims the top spot on the Immortal Realm's culinary rankings, rises to become the God of Cuisine across the three realms, and carves out her own path in the immortal world through the warmth and bustle of everyday cooking.
