Just like Jacob had said, the meat was indeed not tasty. It was sour and bitter with an awful texture. Furthermore, its texture was terrible as if they were chewing cotton.
However, it was better than starving to death. Jacob had extraordinary abilities right then. Even if he had gone half a month without food, he wouldn't starve to death. He took only a bite before putting down the food in his hand as he no longer had the appetite to eat it.
However, Jurnee was different. She had received special training. What hadn't she eaten in the wild? In comparison, she could accept the meat of that unknown creature.
For people like her, they no longer ate to satisfy their appetite but purely for survival instead. In the words of her instructor, delicious food was merely a trick to the tongue. As agents, they had to adapt to any situation at any time. If they wanted to survive against adversity, they had to learn to consume anything. Only in that way could they save their lives.
