Autumn Fair
Elaina's grandparents took their chance to fully study the behaviors of the Wild Cows after seeing Elaina tame them. Having a chance to fully study them up close without the need to exterminate them or hide in the distance is a big contribution to the Adventurer's Guild.
Elaina also gave them tips about the Wild Cows. After all, observation alone will not give them the right information, they also need to learn things that others have already uncovered and learned.
As for the reason why they came there, it seems it involves the matter of the Merfolk's attack. Of course, that matter was easily resolved after Elaina and the others gave their testimonies so for the rest of the day, the old couple on the farm just stayed behind to watch and observe the work being done on the farm while also bonding with their granddaughter.
While having a good time with her grandparents, Elaina suddenly felt movements on her belly.
