The anti-cold medicine is Shadow Steak, which is difficult to make and cannot be made if the ingredients are correct. The "Shadow Steak" recipe: 20 purple fruits, 8 anesthetics, 3 high-quality meats (need to be fresh! Cooked and dried ones are not good. This is the most difficult part. This meat is not easy to preserve. After killing a large dragon, put it on the dragon and then go home quickly.) 2 mushrooms, 1 potato, 1 carrot and a bottle of water are the best fuel. Use wood instead of igniting powder. Remember to take out the charcoal immediately
