At Ren's place, two days had passed since he began designing the vehicle he would use for his long journey. The blueprint was complete, but one major challenge remained—finding the right materials for its components, especially the tires and engine.
Rubber was the ideal choice, but Ren wasn't sure if such a material even existed in this world. If not, he would have to find an alternative with similar elasticity. This wasn't just about building a vehicle—it was about reverse-engineering technology from scratch.
At that moment, Ren heard news that a merchant caravan from the east had arrived in Vermont. Not wanting to waste the opportunity, he immediately headed to the marketplace, hoping to find something useful.
And—
Yep.
Among the various stalls, Ren's eyes caught sight of something interesting. A dark, solid material with a slightly flexible texture, similar to hardened rubber sap.
Excited, he approached the merchant.
