When Yao, who fell ill from poison, was able to return to work at the medical office, a large amount of books arrived at Maomao. The sender is an arhat who is a strange soldier. It seems that he has made a large number of Go textbooks and pushed them on Maomao. Contrary to Maomao's idea of selling it because he is not interested, Arhat's book will spread the popularity of Go in the court. On the other hand, in addition to his already busy life, Mr. Jin was extremely busy with reports of poisoning and locust damage by the shrine maidens of Shaou. Meanwhile, Mr. Jin learns that a Go tournament is being planned in the imperial court and goes directly to negotiate with Arhat. Instead of offering the venue in Mr. Jin's name, he persuades him to do the work he has been slacking off.
