Delivery boy Lin Ye never thought that the small blue and white jar he randomly picked up from the flea market would involve him in a turmoil that spanned time and space.
A spoonful of "Wangyou Powder" from ancient times made the ordinary egg drop soup he cooked become "the most delicious taste in the world" sought after by the imperial kitchen. It also caused him to be blocked by a mysterious man in official uniform at the entrance of the alley and bumped into the foggy "back alley".
See how an ordinary person who was forced into a desperate situation by the rent stirred up the storm in ancient times with a spoonful of seasoning, and used fireworks to fight against power and conspiracy.
