The New Slimes, with the Slimes

Suraimu-tachi to Shinshu no Suraimu (スライムたちと新種のスライム)

The Merchant Guild requests from Ryoma a large order of waterproof cloth for the seasonal Quell Frog hunt and he decides to produce them inside the mines and Eliaria accompanies him to practice with her violin. One of his slimes evolve into an iron slime after eating some iron. Eliaria later asks Ryoma makes a small statue of hers. Satisfied with the result, he ends making up statues of all members of the Jamil estate, and they decide to have her take them as a memento for when she leaves for studying, including one of Ryoma. 

Later at the shop, Ryoma learns that sales and profits keep increasing as Bamboo Forest's reputation grows and he realizes that he forgot to give holiday breaks to his employees, who rejoice when he decides to do so. Afterwards, he learns from the Adventurer's Guild that a group of adventurers captured a new kind of slime. As such, he buys it from them. By apprising the slime, he learns that is a blood slime. Watching his progress, the three gods rejoice on their decision of picking Ryoma. Later at home, Eliaria invites Ryoma for a taming magic training session with her family.
