Back at the secret villa, young master Xue thanks Dr. Edward for teaching him how to use traditional Chinese medicine. He says that if he really wanted to learn Chinese medicine, he should try to help the hospital's patients. The secret villa's owner, lintianhu, promises to chop off the ears of yunfan if the young master succeeds in destroying her. He also says that he'll give him all of the drug trading networks in chuanzang's hometown if he succeeds in killing the old man. The old man, yaksha, says that with his brahmin he doesn't have to worry about killing a pesky bug. He remembers a time when an entire village got infected with sars, a similar strain of influenza, but the government couldn't do anything about it. The entire village was set on fire and the entire region was struck by a pandemic. They need to find the source of the poison and find the herbs that can make the antidote.
