Chen Mo, the soldier king who retired due to injury and lost his sense of taste, was forced to return to his hometown and took over the dilapidated restaurant left by his grandfather that was about to close down. He just wanted to live an ordinary life, but unexpectedly discovered that the greasy back door of his home was connected to a bizarre "world of mountains and seas." The customers here are very special: the shy ginseng doll who likes to exchange rare medicinal materials for braised pork, the nine-tailed fox temporary worker who always wants to buy on credit but his tail can be used as top-quality ingredients, and the ignorant mountain spirit who comes to buy milk tea with luminous ore... Chen Mo held an iron spoon in his hand and sighed as he looked at a group of eager "inhuman" customers and the developers who were eyeing the door. He just wanted to cook a meal quietly and regain his sense of taste. How could he become a "hidden boss" who protects the balance between the two worlds and uses human fireworks to heal the hearts of gods and demons?
