Ch. 502Supply and Demand Are Truth
Kaka escaped the turmoil on Treasure Island and became a senior craftsman in the Resurrection Kingdom, where he and Buji developed the idea of using bone as a structural material. After the Bone Stalk Giants debuted through the Gene Sequence, Kaka and Buji questioned whether Bone Construction still had a future.
- Kaka, a gifted forger on Treasure Island, was pressured to make deadly devices and rejected by the Invention Department, which judged his background and work to be disgraceful.
- Kaka fled Treasure Island with his father and Little Dot when imperial war brought military levies and violence to the island.
- Kaka joined the Resurrection Kingdom as a senior craftsman and met Buji, who argued that broad access to foundational knowledge was essential for the kingdom's progress.
- Kaka and Buji proposed using bone with wood, stone, and metal to build structures and devices, then documented their research in an application to King Raymond.
- King Raymond approved their Bone Construction plan and granted the resources they requested, so Kaka and Buji began assembling a research team.
- The Bone Stalk Giants led by Hero Xidar debuted on the battlefield, and their Gene Sequence strength caused Kaka and Buji to doubt Bone Construction's value.
