Wang Dachui is struck by lightning while making a delivery and lands in a soup pot in the imperial kitchen. The moment he climbs out, the head imperial chef pins him to the ground, accusing him of "breaking into the palace to poison someone." In desperation, he clutches half a string of grilled kidneys and shouts, "This stuff tastes way better than your lousy soup! Try it if you don't believe me!" The head chef takes a bite and freezes on the spot. No one in the Great Yan Dynasty has ever tried "spicy grilling" before, and the aroma is so good it brings tears to his eyes.
