Rocky had heard of establishing a land base, but he never considered it feasible since he felt certain he lacked the conditions and capabilities required for such a significant undertaking.
However, after occupying Backhill Village, he felt that he could consider this matter now!
The resources in the sky were extremely scarce—it could be said there was nothing but sunlight. However, land was different. It had minerals, forests, crops, and even countless Demons—all of which were resources. In order to obtain these resources to develop and expand Sky City, the idea of a land base was thus conceived.
The purpose of this idea was to establish a base on land that belonged to him, turning it into a dual-core setup alongside Sky City, and then continually supply resources to Sky City, allowing it to grow and develop incessantly.
