Saiunkoku Monogatari 2nd Season EP7 - Wholeheartedness Penetrates Stone

As the doctors go over Dōshu’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. Shūrei hears of one who can and remembers that he is an old family friend. Dr. Yō agrees to go to Sa Province and to also train all the doctors along the way. Using Dōshu’s texts as an incentive, Shūrei gets the Merchant’s guild to agree to send aid as well.
