As the doctors go over Döshu’s texts, they stumble upon the cause and treatment for the illness. The only way to cure it is for the patient to undergo surgery. Unfortunately, none of the doctors present knew how to perform it. Shürei hears of one who can and remembers that he is an old family friend. Dr. Yö agrees to go to Sa Province and to also train all the doctors along the way. Using Döshu’s texts as an incentive, Shürei gets the Merchant’s guild to agree to send aid as well.
