With their model airplane completed, Ash and Hermes decide to stun Itsutsu's populace by doing a surprise demonstration at an upcoming event. And stun them they do-immediately, their detractors' mockery dies out as swathes of excited people stumble over each other to volunteer to help with making the final product.Ash isn t about to turn them down. In fact, he has the perfect project for them to start working on: making bricks!From the outside in, the process doesn t seem too difficult: pour clay into a mold, stick it into a hot kiln, and pop out a completed brick. But unfortunately, the gang runs into roadblocks at every turn. Suddenly, they find themselves scrambling to secure a supply of the correct kind of clay, struggling to build kilns that can withstand high temperatures, and delicately navigating the local politics of Itsutsu s craftsman workshops.Still, Ash and his friends don t lose hope. Their dream of building a cornerstone for a new tomorrow? It s just on the horizon!
