Finally, Leon decides to come clean. Leon had killed the blacksmith that made those knives, after he said that he would make better set of knives than the Seven Stars Knives. Knowing that he cannot let that happen, he stabbed the blacksmith and pushed him off the cliff. When he finally come to his senses, he deeply regrets his actions. His mistake was to tell the elders in the Underworld about the incident.
After encouragement from Mao, he starts in making his dish. Special skills: Removing meat from crabs with knives (picks even the leg clean). Special ingredients: Crab shell (when he picked the crabs, picked the small, inferior ones. The crab meat is stuffed into the shells, and when deep fried, the crispy shell can be eaten). While Leon was busy with his dish, Shan lazed around and even mingled with the judges. Her dish was a bowl of soup and crab omelet.
Then it was tasting time. Shan went first. The judges were not thrilled with her entry. It was a normal fare. However, when the judges tasted Leon’s stuffed crispy crab shells, they spat out the crab while saying that it was the most disgusting thing they have tasted. How could it be? Everyone was surprised. Was it sabotage? But how?
